Description

one

This invention relates to machine tool making and can be used in () waping machines.

Devices are known for accurately para- metering the working body of the machine, comprising a copier mounted on the rotary cam, on which the working body rests. Such devices are used to obtain a worker. course when moving the node in one direction. Returning to the initial position requires idle 1.

Pel of the invention is an increase in the quality of processing and techno; Logical capabilities due to the exclusion of idling.

The palm is achieved by the fact that the device is equipped with a rack-and-pinion gear with rotational drive and screw stops for limiting travel, an additional eccentric and gears rigidly connected with the eccentrics and the mouth of the box with the rail. Wherein

eccentric eccentrics are shifted in opposite directions and equal in magnitude.

FIG. 1 depicts the proposed device, front view, in FIG. 2 the same kind of saadi.

Claims (2)

The device contains a non-rotary rotary table 1, connected through a ball valve 2. With a driven vaprm 3. Daggali 5 is fixed on the face plate 4, the spindle is 6 s. abrasive tool 7 is installed on the guide rolling. The device also includes a drive 9, through a screw pair 10, moving a support 11, on which on eccentric shafts 12 there is installed a copier 13 connected to spindle 6 via ea 14. On the support 11 there are two screw stops 15. On an axis 16 a rack gear is fixed 17, kinematic connected with shafts 1 2. The rotation of the gear-17 rail is effected, for example, by a pneumatic cylinder 18. The device is also equipped with an indicator 19. The device operates as follows. When you turn on the drive 9, the caliper 11 receives the movement from the screw pair 10. The angle of the copier 13 is set depending on the removed allowance and. It is determined by one of the screw stops 15, which restrict the rotation of the reystestern 17. When moving the support with the cam, the axial movement of the spindle 6 takes place until all the allowance is removed. After that, due to the rotation of the Reiki Gear 17 from the pneumatic cylinder 18, the eccentric shafts 12 are rotated, as a result of which the angle to the side of the copier 13 is reversed. The rake - above the turn 17 is pressed against the second stop 15. At the same time, the spindle 6 is retracted to its original position. The cycle can be repeated during the return stroke of the caliper 11. The device has sufficiently high rigidity, reliability in work and accuracy of movement of the working body 874 Claim 1. Inventory device for precise movement of the working body of the machine, which are movable relative to each other and elastically interconnected a working srgan and a copier mounted on a rotary eccentric, which is different in that, in order to increase the quality of processing and technological capabilities, the device is equipped with the company and screw stops of the stroke, additional eccentric and gears, rigidly connected with the eccentrics and installed with the possibility of kinematic closure with the rail. 2, The device according to Claim 1, in that the eccentric eccentricities are shifted in opposite directions and equal in magnitude.
