    (54) DEVICE FOR DIRECTED SUPPLY OF AUXILIARY SUBSTANCE
    The invention relates to a device for the directional supply of an auxiliary substance (cb), in particular, to a tool cutting area or tool insertion areas, for example at machine tools G. Machines are known for which the nozzles from which the explosive comes out are located around the spindle carrying The nozzle tool is movably mounted and can be individually displaced manually, so that the outgoing jet can be directed to the wetted position. The disadvantage is that the jet of all or individual nozzles must be adjusted manually or for each nozzle separately, serving the machine, in accordance with the process of processing and its continuation. Therefore, automatic operation of the machine is impossible. Consequently, it is proposed (DE-OS2 437 739) the movement of a movable supply pipe for additional substance by a motor controlled depending on the movement of the supply of working grease from the machine. Provided that, before starting treatment, the feed pipe is directed in such a way that the outgoing coolant stream can get to the front body of the drilling tool, it is possible to adjust the feed pipe so that mainly the coolant stream is directed to the tool penetration zone . However, a prerequisite for this is taking into account the length of the drilling tool and its use for positioning the feed line before starting the drilling process. For this, the proposed price for machine tools with a tool changer device is provided for a gauge that measures the length of the tool, the tool in the magazine in the ready state. The positioning of the probe is memorized, and the storage device turns off the adjusting motor if the positioning of the supply line does not correspond to the positioning of the probe. Thus, the automatic mode of operation of the machine. : The disadvantage is the necessary expenses for the sensing device and for further processing in this way of the obtained information. Moreover, sufficiently accurate information for the adjusting mechanism can be obtained only for drills and similar tools. For example, in cutting heads, the information obtained by probing cannot be used to accurately establish the supply pipeline to the cutting area of the tool. Obviously, the proposed solution is not intended for this. As for the degree of use, it turns out that it is not profitable to use only one separate supply pipe, in particular, when high-pressure explosives are supplied, since a lot of explosives bounce off the wetted area without impact, and in addition, when drilling, explosives can enter the drilled hole only at intervals, which is due to the shape of the drill, namely, when the groove of the drill is briefly released in place, on which the second stream of auxiliary substance falls. The possibility of simultaneous and in the case of both manual and automatic rearrangement of several nozzles illustrates the solution offered by the copyright certificate SU56580a. Here, the central ring has a single guide slide, in which there is a pin connected to a rotatable nozzle. The guide slide is angled relative to the axis of rotation of the nozzle. When the ring is rotated, the guideway shifts the axle tangentially relative to the nozzle support, due to which it rotates around its own axis of rotation. Taking into account the permissible dimensions, this solution allows for turning the nozzles only to a relatively small angle of rotation, as a result of which the jet of explosives can reach only a relatively small area. However, for example, on milling machines, tools are used whose dimensions in the direction of the axis of which are different, such as drills and disk mills. The direction of the explosive jet to the cutting zone of both the drill and the disk cutter requires a relatively large angle of rotation of the nozzle. Further, the rotation of the nozzle leads to different angles of contact of the jet BB on the instrument, due to which, depending on the angle, more or fewer explosives bounce off the instrument without affecting, and only part of it acts on the instrument. In addition, with an increase in the acute angle between the axis of the nozzle and the axis of the tool, the movement of the nozzle occurs at a smaller angle if the angle of impact of the jet of explosives on the tool continuously follows the shifting cutting and cutting zone. Thus, a mechanism with very precise control is required. The disadvantage of this solution is that it allows only the joint movement of all nozzles. For applications in which different jets of explosives fall on different zones, for example, on a tool or product, the solution is not applicable. The disadvantages of the known solution are caused by the use of the control part common to all nozzles and the fact that the change in the position of the nozzles occurs by turning. The use of a guide link for turning the trunnion allows only a small angle of rotation with acceptable sizing. The purpose of the invention is to achieve optimal use of the auxiliary substance and in multi-blade tools - by means of its directed feeding to the zone of application; the distribution of the auxiliary substance also over large surfaces, for example, feeding to the zone of axial section, as well as to certain areas of the workpiece to cool them, or through the entire free length of longer instruments; the creation of a device serviced manually or automatically, which directs one or more jets of the auxiliary substance to points located at different distances relative to the front end of the spindle, and the explosive jet falls either at a different angle, or the angle of the jet should pass a relatively large range of angles. Explosive jets must be re-installed either jointly or separately. The entire structure of the device should not allow the change of the corresponding jet of explosives due to the forces that occur when the explosives are supplied under high pressure. The goal is achieved by the fact that at least one of the nozzles is a follower element of a crank or screw mechanism, the leading element of which is rotated or pivoted around the axis of the product spindle or around an axis parallel or radially at any angle, either manually or mechanically. to this axis. In this case, the nozzle can move depending on the geometrical ratios of the transfer in (. Or on the headstock radially relative to the axis of the spindle, with the radial plane of motion located at any distance to the center of rotation of the spindle of the product, or it rotates around the axis intersecting the axis of the spindle According to the invention, by means of a crank mechanism, the nozzle is hingedly connected to its connecting rod. The crank is designed as a gear wheel with a pin reinforced on the side of the end face. Compound nozzle rod as its pivotal connection with the crank pin, the crank occurs via a hinge.
    Each nozzle has such a transmission. It is driven either directly from the gear, so that each nozzle has a separate drive, or by a central drive wheel, which is located predominantly concentric with the machine tool spindle and drives a gear wheel so that several nozzles are actuated together with one central drive.
    If the solution according to the invention is made using a screw mechanism, the nozzle is rigidly connected to its nut or via a swivel lever mechanism. This nut is provided with a gear wheel. 3 In this case, the drive is provided either directly for this gear, as a separate drive of one nozzle, or through a central drive wheel, as a drive of several nozzles.
    It is advisable to use crankshaft and crank mechanisms that drive in a single nozzle, performed according to different parameters (thread stroke, crank dimensions), so that the original movement of the central drive wheel leads to different large movements of individual nozzles.
    Another design of the device is obtained due to the fact that individual or all nozzles have a different inclination of the axis of their nozzle channel with respect to the spindle axis of the product during the initial position of the drive wheel. The principle of operation of the device is described by the following examples of performance;
    FIG. 1 shows a rotary nozzle as a driven member of a crank mechanism; on f. 2 radially movable nozzle as a driven element of the crank-connecting rod mechanism; in fig. 3 - rotary nozzle as a driven element of the screw mechanism; in fig. 4 - radially movable nozzle as a driven element of the screw mechanism.
    The nozzle 1 is installed around the axis 2 (Fig. 1) and with the help of a ball joint 3 in the connecting rod 4 of the curvature-studded mechanism, the eccentric disk of which is made in the form of a gear wheel 5 and with a front side of the crank of the crank b. Through another ball
    7-hinge connecting rod. 4 is pivotally connected to the crank pin 6. The gear being driven around the axis 8 engages another gear made in the form of a conical wheel S, which is designed as a central drive wheel located concentrically with the axis 10 of the spindle of the product.
    If the bevel wheel 9 rotates at a certain angle around
    With axis 10, the gear 5 also rotates around its axis a, a, and the pin of crank 6 drives p in a circular arc. Pivotally connected to the crank pin
    5 6 the connecting rod 4 transfers the resulting linear movement through the ball NAR 3 to the opposite end of the nozzle 1 from the nozzle hole, for which it rotates around axis 2.
    0 However, the movement of the crankshaft gear mechanism can be carried out separately, without a central driving wheel, in this case, a bevel wheel 9, by connecting the drive
    5 and the axis 8 of the gear wheel 5. The nozzle 11 (Fig. 2) is depicted as a driven member of a crank drive mechanism, moved forward in a guide 12 located in the front end face
    Q of headstock 13. The nozzle is connected to bar 14, with which the connecting rod 15 of the crank-hinge mechanism is pivotally connected.
    On the other hand, the connecting rod 15 is pivotally connected to the pin of crank 16,
     which is associated with a gear wheel 17 configured as an eccentric disk.
    The gear wheel 17 engages its teeth with the teeth of the other tooth. of the inner wheel 18 serving as a central driving wheel located coaxially with the axis 10 of the spindle of the product ..,
    The movement of the central drive wheel 5, (the gear wheel 18), around the axis 10 causes the gear wheel 17 to rotate, thereby moving the pin of the crank 16 along a circular arc. Thus, through the connecting rod 15 0 on the ton 14, the linear movement is transmitted to the nozzle 11 connected to the pull 14, due to which it moves in the guide 12.
    The nozzle 19 as a driven element of the screw mechanism is rotatable located on the jAH .Ha axis 20 and opposite to the nozzle opening end is movably connected to the hard 21, which on the other hand is connected to the nut of the main rotor 22

    its axis 24 causes the nut 22 to move in a linear motion, which is transmitted through the lever mechanism to the end of the nozzle 19 and causes it to rotate around the axis 20. The nozzle 25 (fig. F) rigidly connects to the carrier nut 26 27. The screw 27 rotates and rests on supports 28 and 29 and bears a gear wheel, here is a conical ZO wheel, the latter engages with another eubchaty wheel 31, which serves as a central drive wheel, which can be rotated around the axis 10 of the working spindle. The nozzle 25 is installed with the possibility of moving in on the control 32, located at the end of the headstock 33. To connect the supply pipe 34, the nozzle 25 has a connecting part 35, the channel 36 of which enters the channel 37 of the nozzle 25. If it is necessary to rearrange the nozzle 25 , the central drive wheel, (conical wheel 31), rotates around axis 10, and due to the rotation of the tapered wheel 30 also rotates the screw 27, as a result of which the nut 26 performs a single movement, which due to the rigid connection between a nut 26 and a nozzle 25 Directly to the nozzle 25 and scrolling its movement in the guide 32. For each of these and other possible embodiments of the invention, it is possible to drive a curved spike-and-connecting rod or screw mechanism related to each nozzle as through a central drive post with a joint drive of several nozzle mechanisms, and for each nozzle mechanism separately using a drive acting on the crank and screw directly. The drawings do not show the preferred design of linearly movable nozzles 11 and 25, about which they are made with an inclination to the axis 10 of the spindle from the divider, in this case jets the explosive on the product received by the spindle of the product with a constant angle this value. If the nozzle 11 or 25 moves in the guide 12 and 32, the jet of explosives hits the tool or product closer or farther from the end of the headstock 13 or 33, but always with the same angle. This angle is chosen taking into account the optimum use of the auxiliary substance, so that the smallest possible amount of the auxiliary substance bounces off the tool or product without affecting them. ; As a result, the pollution of the environment, the load on the housing or the air conditioning unit of closed machines is reduced. In addition, an optimal supply of explosives is better supported by the machining process. With constant repetitive identical production tasks, the nozzles can receive a different inclination to the axis of the working spindle, due to which the explosive jet of each nozzle in the area of its contact with the tool or product is used optimally. This is possible both for linearly displaceable nozzles and for rotating nozzles. In addition, the rotated nozzles can be moved in a large range of rotation, so that the area of contact with the jet of explosives can be located both in the entire length of the tool and in a certain place of the tool that needs to be cooled intensively. Due to the possible separate drive of the nozzle, it can also be used, for example, to lubricate the surfaces of the machine, for example, to eliminate accumulations of chips that form thermal zones. To do this, it is necessary to constantly move the rotating nozzle over the entire range of rotation. At the expense of a separate drive, it is possible to select a specific position of each nozzle relative to the tool or product, so that a different number of nozzles can meet various requirements in the part of the supply of the auxiliary substance. This has a good choice of the combinations of both nozzle drives and the possibilities of their movement. The invention allows both manual and automatic alignment of individual or several jets of auxiliary substance both by means of a central and a separate drive. Due to this, depending on the work program of the machine and in accordance with the requirements of the machining process, manual OR can take place automatically feeding the auxiliary substance in the cutting area of the tool into the product and to other places on the tool, product and machine tool. In this way, optimal maintenance of the manufacturing process and the use of an auxiliary substance are carried out. As a result, it is possible to operate the machine with maintenance with fewer or no personnel. Claim 1.
