    The device for measuring the engagement lead of the thread of a screw-like work piece, such as a hob, for example, includes a spindle for rotating the work piece about an axis, a measuring slider movable transversely to the axis and terminated with a feeler which is in sliding contact with a flank of the thread of the work piece whereby the path of movement of the measuring slider is angularly adjustable, a sliding carriage supporting either the measuring slider or the work piece to impart a relative axial displacement therebetween, a tachometer generator coupled to the axially movable sliding carriage to generate a signal proportional to the speed of the axial displacement, a sinusoidal potentiometer mechanically coupled to the measuring slider and to an angle measuring and adjusting device to adjust the angular position corresponding to the base lead angle of the thread of the work piece, the output of the tachometer generator being connected via the sine potentiometer to the electromotor for dirving the measuring slider so that the transverse feed of the latter is proportional to its relative axial displacement whereby the deviations from the preset lead angle are continuously recorded.

    Dig a sine ruler according to known trigonometric dependencies. The purpose of the invention is to simplify the setup. The goal is achieved by the fact that the mechanism for synchronizing the movements of the longitudinal and transverse carriages is made in the form of a screw driver of a transverse carriage, an adjustable electric motor associated with the aforementioned screw propeller, two tachogenerators connected with screw engines of a longitudinal and transverse carriage proportional to the amplifier, inputs which are connected with the mentioned tachogenerators, and the output is with an adjustable electric motor, and the unit of proportionality, made in the form of A potentiometer connected between the tachogenerator of the screw driver of the longitudinal carriage and the proportional amplifier. The adjustment is also simplified due to the fact that the sinus potentiometer is kinematically connected with the rotary block of the transverse carriage guides. The proportional amplifier is four-quadrant. allowing reversing of both the direction of rotation of the adjustable motor and the torque without changing the direction of rotation. FIG. 1 schematically shows the proposed device; in fig. 2 is a diagram illustrating geometrical relationships in measuring the main step. The device for measuring the main pitch of the screw threads comprises a base 1, a spindle headstock 2 mounted on the bases with a spindle 3, a tailstock k with a rear center 5, a spindle drive consisting of an electric motor 6 with a gear pair 7 and 8, a longitudinal carriage 9, screw a longitudinal carriage motor 10, a longitudinal carriage synchronization mechanism with a spindle rotation made in the form of a guitar 11 gears, a swivel block 12 transverse carriage guides with an angular limb 13, a transverse carriage T with measuring head Coy 15 screw propeller 16, the transverse carriage and legal for trade regulator motor 17 driving the transverse carriage. 54 The device also includes a mechanism for synchronizing movements of the longitudinal and transverse carriages, containing a tachogenerator 18, kinematically associated with a screw propulsion of a longitudinal carriage, an intermediate amplifier 19, a proportional coefficient unit, made in the form of a sinus potentiometer 20, a second tachogenerator 21, kinematically connected with screw propulsion transverse carriage, and a proportional amplifier 22, the inputs of which are connected to tachogenerators, and the output - with an adjustable drive motor transversely th carriage. The device also includes a setpoint potentiometer 23 for manually controlling the movements of the transverse carriage. The device works as follows. The controlled part (a worm to or a worm cutter) is clamped between the spindle 3 and the rear center 5. The guitar 11 gears of the synchronization mechanism for moving the longitudinal carriage are adjusted to the specified axial pitch P of the controlled worm (Fig. 2). The rotary block 12 of the transverse carriage guide is rotated by the Uprofil angle of the thread, the angle of rotation is marked along limb 13. Then the measuring tip of the measuring head 15 is brought into contact with the profile of the monitored thread at the beginning of the working section of the profile (point A in Fig. 2). This completes the preparation for the measurement. To perform the measurements, the spindle drive motor 6 is turned on, the part to be monitored comes into rotation, and the longitudinal carriage 9 moves with a predetermined pitch of the screw movement due to the transfer of motion through the guitar 11 and the screw propeller 10. In order to measure the main pitch, so that the transverse carriage 1k moves along the side of the thread profile at a speed V sin, where V is the speed of axial movement of the longitudinal carriage. In this case, for one turn of the screw, the transverse carriage moves by the amount y and the measuring tip goes to point B. The measuring head shows the deviations of Pcosjf, i.e. main step.
    The movements of the longitudinal and transverse carriages are synchronized by a proportional amplifier 22, the inputs of which are connected to tachogenerators 18 and 21, are connected respectively to the screw drivers of the longitudinal and transverse carriages, and the tachogenerator 21 is connected to the proportional amplifier directly, and the tachogenerator 18 is connected via a sinus potentiometer 20 (and, if necessary, intermediate amplifier 19), which ensures the input to the input of a proportional amplifier signal V, sin. The proportional amplifier feeds the adjustable motor 17 so that the ratio V is maintained, i.e. synchronization needed.
    The sine potentiometer 20 is kinematically connected with the rotary block 12 of the transverse carriage guides 12, which simplifies adjustment because when the desired position of the transverse carriage is set (J, the necessary proportionality factor () is automatically set).
    The proportional amplifier 22 is four-quadrant. It can work with any polarity of incoming signals and allow reversal of both rotation and load. With this design, it is possible to perform measurements both with the right and with the left rotation of the object being monitored without any changeover.
