    The invention relates to the management of metal-cutting machines and is intended to create additional rotational movement of the helical gear product of the gear in the tooth-machining δ machine, controlled by electronic-forced movement, operating by the method of helical rolling and having random 'drives for rotating the tool and product. 10
    A device for electronic control of a hobbing machine is known, in which the cutter shaft and the product shaft form pulse sequences depending on the number of revolutions, having a certain ratio for a certain number of teeth of the milled gear in order to achieve a solid gear, and dividers or multipliers of pulse sequences are provided. Both 20 sequences of pulses are compared with each other and from the comparison a control signal is generated to regulate the drives of the product, so that there is a forced movement of the drive of the product 25 depending on the drive of the cutter. To obtain the additional rotational motion necessary for a helical product, additional pulses are created, which are added by addition or subtraction to one sequence of pulses [11.
    The disadvantage of this device is the low speed and accuracy of the device.
    Closest to the proposed device is the stump control of a gear grinding machine with an electrically controlled spindle drive of the product, which uses the known method of creating additional pulses to create additional rotational movement of the helical gear, a device containing sensors connected through actuators to the inputs of actuators .
    In this device, the measurement of the carriage path of the product is carried out indirectly, i.e. through the ball screw assembly, in which the ball screw
    833174 screw is connected to a pulse speed converter. The generated pulses are fed through the frequency divider circuit to a coordination circuit containing a digital-to-analog converter, to which the instrument pulses created depending on the number of revolutions are fed, i.e. grinding wheel and products [2].
    A disadvantage of the known device is that when using a ball screw assembly for measuring the path, at best, an error in transmission from 0.002 to 0.003 mm, which is too large to grind the sides of 15 teeth of particularly precise gears, should be considered. Other inaccuracies arise from the fact that the coordination scheme compares the directly divided by frequency pulse train of the product pulses, the multiplied and divided pulse sequence of the carriage of the product and the multiplied and divided pulse sequences of the tool with the pulse sequence of the product.
    The purpose of the invention is to improve the accuracy of the working speed of the device,
    The goal is achieved in that the device for controlling the machine tool for machining helical product comprising a first encoder, the second encoder, the outputs of which are connected to the controller, the third pulse generator, whose output is connected to the regulator, introduced pulse generator 35 constant cha- simplicity, to the output of which a divider is connected, a counter connected to the share and to the third pulse sensor, a second divider, which is connected on one side to the counter through the first element And, 40 . controlled by the third pulse sensor, and which is connected to the pulse generator on the other side, the third divider is connected to the third pulse sensor, the outputs of the second and third divider are connected to the second element And, and the outputs of the third pulse sensor pulsed by the generators of the third divider are connected to the third AND element, while the second and third AND elements are connected · to the OR element, the OR element is connected to the fourth AND element, controlled by the third pulse sensor, and the control input is third a divider connected to the output of the OR.
    The drawing shows a functional diagram of the device.
    The device contains a digital-to-analog converter 1 with output 2, the first pulse sensor 3 (angle of rotation of the tool) with output 4, the engine 5, the second pulse sensor 6 with output 7, controller 8 with output 9, the third pulse sensor 10 with outputs 11 and 12, installation body 13, differential 14, reversible switch 15 with outputs 16 and 17, memory unit 18 with outputs 19 and 20, multipliers 21 and 22 with outputs 23 and 24, respectively, OR element 25 with outputs 26 and 27, constant frequency pulse generator 28, divider 29, counter 30, memory unit 31, first element 32 AND, second th divider 33, second element 34 AND, element 35 OR with output 36, fourth elements 37 AND, third divider 38 with input 39, third element 40 AND, counter 41 with outputs 42 and 43 and setting element 44.
    To grind helical cylindrical wheels, it is necessary to create an additional rotational movement for it, which can be carried out in a well-known manner by means of a mechanical differential gear equipped with interchangeable gears, or mainly. by creating additional pulses coming to the controller 8. The device for the specified creation and supply of pulses that cause additional rotational motion, called the electronic differential. To create the necessary travel information about the carriage movement, a well-known digital system is provided. measuring the path, consisting of an optical scale and a read head attached to it, with the optical scale mounted on the carriage and the reading head mounted on the caliper body. The read head generates 3 ^ pulses depending on the path. Thus, the measurement of the movement of the carriage and thus the gear κο / ggca is carried out directly on the carriage, i.e. without the aid of mechanical transmission elements such as a gear rack and pinion, ball screw and ball nut, gear, etc. For this reason, there are virtually no mechanical sources of error.
    Travel information comes from the sensor 10 in the form of 1% pulses to the electronic differential 14. The last data is entered that is necessary for the ratio of the carriage movement to the additional rotational movement, namely the module tn, the number of teeth χ and the angle of inclination of the teeth (d subjected to grinding of the helical gear , the double radius of the pitch circle of which is, as is well known, u-z / cos | b · 5 The data mentioned are called the factor Ί).
    At the same time, in order to create additional rotational motion, there should be (A certain ratio of the number of pulses of the actual value 1 ^ of the product to the number of scale pulses created depending on the path, each time per unit of time. This ratio represented by factor 1z is calculated as follows
    Iv /
    B · ’_ w *
    - ————----- 6-ih a,
    -Itmzq, where I w - the number of pulses of the product per unit time;
    - the number of scale pulses per unit time;
    N w is the number of product pulses per revolution;
    Oh - the constant of the scale (the number of pulses per meter).
    Thus, the correct ratio is obtained by calculating and setting factor b.
    To enter factor b into the electronic differential 14, an adjusting organ 13 is provided. Taking into account factor t), including the direction of the helix of the teeth and the direction of feed of the carriage, the pulses are processed in the electronic differential 14, and, as indicated below, a preselected multiplication is also carried out 1 m track pulses in order to increase the resolution of the path measurement.
    The signal obtained by processing in the electronic differential 14 enters in the form of a train of pulses 1 ^ * 1) to controller 8, in which the train of pulses Tdd-b is superimposed on the train of pulses Ις mounted on the instrumental spin. Actually, the sensor 3 in order to create a signal that influences the engine 5 of the product and creates in a very precise way the necessary additional rotational movement, in comparison with the pulse sequence I of the drive of the product. According to the method used in the device, it is created at the beginning of each interval limited by two successive scale pulses p -1 of intermediate ones during the varying periods of the pulse repetition of the optimoscale is carried out with a uniform distribution. . feed speed kareg6
    QCD in a temporarily, at least approximately uniform sequence, a fixed constant number of intermediate pulses — in other words, a pre-selectable multiplication of the scale pulses G m of the sensor 10 by a certain factor p is made so that the corresponding number of pulses of the frequency can be input. with respect to the distances between the strokes of the scale of the path measurement system, not in steps, but gradually, the corresponding distances p-1 of the intermediate pulses for a certain of the first period (.I), sequences of scale pulses. are determined according to the invention on the basis of measurements of the previous period (i-1) · The carriage sensor 10, which moves in both directions of the gear axis, transmits travel information in the form of 1 m pulses arriving at block 18 memory.
    These pulses Ϊ | λ are also supplied to the OR element 25.
    Pulse generator 28 generates pulses of constant frequency, comprising, for example, 1 ΜΠι. The frequency pulses are fed to the input of the divider 29, which reads the incoming pulses and, after reaching a certain number of pulses, gives one pulse to an additionally turned on counter 30. In this case, the partial factor of the divider is equal to the aforementioned factor P of the multiplication of scale pulses сов. Λ . It can fluctuate approximately in the range of 4-64, and for factors below 4 the obtained increase in the resolution of large-scale pulses plays almost no role, and for factors above 64 complex electronic equipment is required and pulsed-scale collisions do not allow high expanding ability.
    In the counter 30, used for measurement -. periods, output pulses of the divider. 29, i.e. frequency pulses / p are read continuously until the next large-scale pulse appears. At this point, the content from the counter is overwritten in block 31. For this, the output of the counter 30 is connected to the first input of the 32 And element, and the second input of the 32 And element is connected to the output element 25 OR. The supply of scale pulses resets the readings of the divider 29 and simultaneously the counter 30. Thus, in each period (I) the scale pulse and divided by the factor p, the number of frequency pulses £ 4 are read and stored in block 31, where they are barely stored -; of the next period 1 4gl (And +1) and only the scale impulse I (And + 1), following the causing pulse of the scale I w (h), causes the content to be transferred from counter 30 to block 31 and at the same time returns 15 counter 30 in the starting position in order to start a new counting conductive successive scale pulses and intermediate pulses are distances in each period and uniform scale pulses based on a previous certain period.
    The output pulses of the divider 33 are supplied through an AND element 34, an OR element 35, and to two AND elements 37, and depending on the switching position of the block 18, to one of the outputs 19 and 20.
    In order to achieve exactly the p-1 intermediate pulses at the beginning of each period of scale pulses in such a way that for each longer period there is a break in the generation of pulses for each more than one cycle.
    From block 31, the content from the counter enters another divider 33, which counts 20 incoming pulses of constant frequency and, after reaching the number of pulses from the pulse generator 28, produces an output pulse, after which it returns to its original position 25, starts reading again until the number is reached B, again gives an output pulse, etc., ; Thus, the frequency of the output pulses of the divider 33 is £ a = f l C and can change 30 in accordance with the available in a short period unnecessary intermediate pulses of an increased frequency V you immediately immediately after the start of the next moment contain the counter number of the previous period of large-scale pulses. On the other hand, the content from the divider 33 consists of read ^ during the period 1 4dl and divided by a constant number p of pulses of the pulse generator 28 of the frequency, i.e. it makes up
    The current period is provided along with element 34 AND and element 35 OR divider 38 and element 40 AND with three inputs. The counting input of the divider 38 is connected to the output of the OR element 35. The control input of the divider 38 for its return to the zero position is connected to the output of the element 25 OR. The output of the divider 39 is connected to the input of the element 34 AND to the input of the element 40 I.
    The output pulses of the divider 33 pos / usually go through the element 34 AND and the element 35 OR to the input of the divider 38. As soon as the divider 38 reaches the capacity ~ p ~, it blocks the element 34 I. Only at the next scale pulse the divider 38 frees the element 34 And so that he is returning under the influence of scale and pulse to the zero position.
    Therefore, the driver 33 have output pulses of the following frequency de45
    Where
    - frequency of large-scale pulses.
    Thus, the output pulses of the divider 33 form a sequence of pulses whose frequency is equal to the frequency of the scale pulses multiplied by a constant factor p. In other words, a sequence of scale pulses with p -1 intermediate pulses between, however, if the divider 38 at the arrival of the next scale pulse I has not yet reached capacity p, then when this next scale pulse arrives, the pulses of the frequency pulse generator 28 arrive in the form of correcting pulses I k to element 35 OR. Thus, the divider 38 continues to read until it reaches the capacitance P, after which it blocks the element 40 And and returns to the zero position. Since the pulse frequency of the pulse generator 28 is much higher than the frequency / s of the output pulses of the divider 33, the pulses of the pulse generator 28 are transmitted long before the output pulse of the counter 33 after the large-scale stroke 42 and 43. However, the division of the pulse.
    To set the value of the additional rotational movement of the gear-product, one should take into account its data, 5 for example, module Ж, the number of teeth z and the angle of inclination of the teeth β, and multiply the incoming pulse train of the divider 33 by the corresponding factor b, which is less than 1. For this include adjustable multipliers 21 and 22, which are equipped with an adjusting body 44. The number of bits of the multipliers 21 and 22 determines the accuracy of the device. In this case, it is advisable to provide 18 15 binary digits. The reversing switch 15 can be switched by means of the adjusting body 44 in order to take into account the direction of the helix of the product - the gear wheel, i.e. direction 20 of the angle of inclination of the teeth r. The reversing switch 15 has two outputs 42 and 43 related to the direction ^ of additional rotational movement of the gear wheel, with one output 43 25 representing a channel for direct rotation, and the other output 42 a channel for reverse rotation of the gear product. If, for example, the adjusting body 44 has an output signal with 30 one binary level, then the output 23 is connected via a reversing switch 15 to the output 43, and the output 24 is connected to the output 47. In the case of the output of the adjusting body 44 with another binary level 35 the output 23 is connected to the output 42, and the output 24 to the output 43. The pulse-incremental information I'40 located on one of the outputs 43 and 42 about the position of the product carriage is then divided in order to prepare a signal for the controller 8 of the forced control system izheniem so that the controller 8 is supplied to the coarse position 45 is not notified in the form of digital-incremental, or rather in analog position notification can be carried out by any other factor. The content of the counter 41 is fed to a digital-to-analog converter 1 connected to it and issuing the corresponding analog signal to the regulator 8.
    The proposed device allows to increase the cutting speed and the accuracy of the processing of the sides of the teeth by the method of screw rolling.

A disadvantage of the known device is that when using a wap ball screw for measuring the track, it should be considered at best a transmission error of 0, OO2 to 0.003 mm, which is too large for side grinding sides of the teeth of particularly precise gears.

To grind helical gears, you need to create it has an additional rotational movement, which can be carried out in a well-known way through {; / 1 mechanical differential gear equipped with interchangeable gears, or advantageously. by creating additional pulses to the controller 8. The device for this creation and supply of pulses that cause an additional rotational motion is called an electronic differential. A well-known digital system is provided to create the necessary travel information about carriage movement. measuring the path, consisting of an optical scale and an adapter that connects to it, with the optical scale attached to the carriage and the coupling head attached to the support body. The reading head creates, depending on the path, the impulse L i. Thus, the measurement of the movement of the carriage and thus the gear is carried out directly on the carriage, i.e. without the assistance of mechanical transmission elements, such as a toothed rack and she- stubble, a ball spindle and a gear nut, etc. For this reason, there are almost no mechanical sources of error. The traveling information comes from the sensor 10 in the form of pulses T to the electronic differential 14. In the latter, the data necessary for the relation of the movement of the carriage to the additional rotational movement is entered, namely 58 module tn, number of teeth 2 and the angle of the teeth inclination (b subjected to grinding helical gear wheel, the dividing radius of the pitch circle of which is, as is well known, ui-g / cos. The afore-mentioned data is called the factor tj. In order to create an additional rotational motion, there must be a definite relative Determining the number of pulses of the actual value of 1 product to the number of scale impulses created depending on the path 1 each time per unit of time. This ratio represented by factor b is calculated as follows .. It is mxo, LL where 1 is the number of pulses of the product per unit of time; INV - the number of scaled pulses per unit of time, the number of pulses of the product per revolution, O - constant scale (number of pulses per meter). Thus, the correct ratio is obtained by calculating and setting the factor b. To enter the factor b into the electronic differential 14, an adjusting body 13 is provided. Considering the fact b. Including the direction of the helical line of teeth and the direction of the carriage feed, the pulses 1 (the oscillator is processed in the electronic differential 14, and, as indicated below, selectable multiplication of track pulses 1 | "And for the whole $ 1x increase the resolving power of the path measurement. The signal obtained by processing in the electronic differential 14 arrives in the form of a sequence of pulses to the controller 8, in which The impulse efficiency Tjvv is superimposed on the sequence of pulses Ig installed on the instrument spindle of Sensor 3 in the circuits, creating, by comparison with the sequence of pulses of the I drive of the product, a signal affecting the motor 5 of the product and creating the additional alternating movement in a very precise way. is created with the beginning of each interval, limited by two successive large-scale pulses 46 l in a temporary, "at least near In a friendly, uniform and sequential manner a certain constant number of intermediate pulses — In other words, a pre-selected multiplication of the scale pulses Gdd of the sensor Yu by a certain factor p is carried out in such a way that the corresponding number of p -1 intermediate pulses are input during varying pulse repetition frequency periods 1, The optical scale is carried out with as uniform a distribution as possible. Since the speed of movement of the carriage feed varies with respect to the distance between the strokes of the scale of the path measurement system, not jumps, but gradually, the corresponding distances p − 1 of intermediate pulses during a certain period 1 ,, (. And) successively large scale pulses 1e. Are determined according to the invention on the basis of the previous period .. (and -1). A carriage sensor, U, which moves in both directions of the gear axis, transmits the travel information in the form of 1 dd pulses to memory 18. These 1c pulses, in addition, are transmitted to element 25 OR, Pulse generator 28 generates a pulse of a constant frequency, for example, 1 MPx, Frequency pulses. - enter the input of the divider 29, which reads incoming pulses and, after reaching a certain number of pulses, gives one pulse to the additionally impacted AOR counter. The partial factor of the divider is equal to the aforementioned factor P of multiplication of the scale pulses 1.D, It can fluctuate approximately within 4-64, moreover, for a fact (fow is lower than 4,. The resulting increase in the resolution of large-scale pulses plays almost no role, and for factors above 64 a complex electronic obsrudovo-niya and (shvbki pulsed The scale does not allow high spreading capacity, In the counter 30, which serves for measuring periods, the output pulses of the divider, 29, i.e., the frequency pulses f / p are continuously measured until the next large-scale impulse 1. At this moment, the content from the counter is rewritten in block 31. For this, the output of the AO counter is connected 7S3 to the first input of element 32 AND, and the second input of element 32 AND is connected to the output of element 25 OR, the feed of the scale impulses 1 resets the divider 29 n simultaneous) counting 30. T In this way, in each period - (jw d) a large-scale pulse and, divided by a factor p, the number of frequency pulses are read and stored in block 31, where they are stored for a next period (AND + 1) and only the large-scale pulse 1 (), the next for the invoking scaling pulse 1d (I), it starts transmitting the content from the counter 30 to the block 31 and at the same time returns the counter 30 to its initial position in order to start the new counting cycle. From block 31, the content from the DZ counter goes to another divider 33, counting incoming pulses of a constant frequency j, and after reaching the number of pulses coming from the pulse generator 28, issuing an output pulse, after which it returns to its original position, t, gives the output pulse again, etc. So, the frequency of the output pulses of the divider 33 is {a -, C and can be changed in accordance with the content currently available from the counter 30 to the previous period and large impulses. On the other hand, the content of the divider 33 consists of readings during period I and divided by an equal number p of pulses of a pulse generation 28 frequency f, i.e. it is C-T .. rIw4 Therefore, the output pulses of the divider 33 have the following frequency P -1-1 4. . -p p and with S xd, 4 where is the frequency of large-scale pulses. Thus, the output pulses of the divider 33 form a sequence of pulses, the frequency of which is equal to the multiplying frequency by a constant factor p of the frequency of the scale pulses. In other words, a sequence of large-scale pulses with p-1 intermediate pulses between 4, two successive pulses next to each other, with the distances of the intermediate pulses being equal in each period of the large-scale pulses on the basis of the previous period. The output pulses of the divider 33 go through element 34 AND, element 35 OR, and two elements 37 AND, depending on the position / position of the block 18, to one of outputs 19 and 20. In order to achieve exactly p-1 intermediate pulses at the beginning for each period of scale impulses in such a way that for each longer period there is an interruption in the generation of impulses, for each shorter period additional excess intermediate impulses of the lower frequency are introduced immediately after the beginning of the next period s are along with element 34 AND element 35 OR divider 38 and element 4О AND with three inputs. The counting input of the divider 38 is connected to the output of element 35 OR. The control input of the divider 38 to return it to the zero position. Connected to the output of the element 25 OR. The output of the divider 39 is connected to the input of the element 34 And to the input of the element 4O I. The output pulses of the divider 33 after- |; usually blunt through element 34 AND and element 35 OR to the input of divider 38. As soon as divider 38 has reached capacity p, it locks element 34 I. Only at the next scale impulse 1y, divider 38 releases element 34 and in such a way that it returns Scale pulse to zero position. However, if divisor 38 arrives at the next large-scale impulse I / not of capacitance p, then the arrival of this next scale is impu. Ls pulses of the frequency generator 28 frequency come in the form of corrective pulses 1. to the element 35 OR. Thus, the divider 38 continues to read until now, until it reaches the capacitance p, after which it locks the 4O AND element and returns to the zero position. Since the frequency of the pulses of the pulse generator 28 is much higher than the frequency j / s. Of the output pulses of the divider 33, the pulses of the pulse generator 28 are transmitted long before the appearance of the output pulse. 96 pulse count 33 after a massive pulse. To set the additional rotational motion of the product of a gear wheel, its data module Un, number of teeth z and angle of inclination of teeth p should be taken into account and multiply the incoming sequence of pulses of divider 33 by the corresponding factor b1 which is less than 1. For this, adjustable multipliers 21 and 22, which are provided with a setting body 44. The number of bits of the multipliers 21 and 22 determines the accuracy of the device. In this case, it is advisable to provide 18 binary bits. The reversing switch 15 can be switched by means of an adjusting member 44 in order to take into account the direction of the helix of the product — the toothed wheel, i.e. the direction of the angle of inclination of the teeth p. The reversing switch 15 has two outputs 42 and 43 relating to the direction of additional rotational movement of the gear product, one output 43 being a channel for direct rotation, and the other output 42 is a channel for reverse rotation of a gear wheel. If, for example, installation authority 44 has an output signal with one binary level, then output 23 is connected via a reversing switch 15 with output 43, and output 24 is connected to a high-voltage connector 47. In the case of an output signal of the installation authority 44 with another binary-35 level output 23 is connected to output 42, and output 24 is connected to output 43. The digital-increment information IO on the position of the product carriage, I, which is present in one of the outputs 43 and 42 as pulse sequences, is then subdivided for the purpose of preparing a signal for the system 8 regulator control forced movement in such a way that the controller 8 is given a rough notification45 of the position in digital-incremental form, and more precisely, notification of the position in analog form. This unit is drying with the help of the counter 41, which in this example considers the execution from zero to. a certain constant number p-1 and then forming a transverse impulse to one short-circuit connected to controller 8 and V4O with stroke 42 and 43. However, the subdivision can be realized using any other factor. The content of the counter 41 is supplied to a digital-to-analog converter 1 connected to it and outputting the corresponding analog signal to the controller 8. The proposed device allows to increase the cutting speed and the accuracy of the side surfaces of the teeth according to the method of screw rolling, Invention 1.
