Abstract

The invention relates to auxiliary devices of metalworking machines and is intended to obtain automatic adjustment of the stroke of the movable working member when processing parts of different configurations. The purpose of the invention is to improve the performance and accuracy of the positioning of the cutting headstock by introducing an additional sensor into the control device with the condition that the sensors are displaced relative to each other in a direction parallel to the axis of symmetry of the cam. The cutting machine command device contains a cam 1 and a command device 8 interacting with it with a sensor 10, which are connected to a movable part of a clamping device 2 including a prism 12 for the product 11, as well as a cutting head 5. The command device 8 is equipped with a sensor 9 so that the sensors 9 and 10 are displaced relative to each other in a direction parallel to the axis of symmetry of cam 1 and mounted with the possibility of adjusting the distance between them. 2 Il. l. 5 00 j th J Pu ..- /

Description

The invention relates to auxiliary devices of metalworking machines and is an improvement of the device according to the author. No. 837631.

The purpose of the invention is to increase the pro-, productivity and accuracy of the positioning of the cutting headstock by introducing an additional sensor into the size of the workpiece 11, taking into account the working stroke reserve.

The device with the condition of displacement of the sensors is the feed of the headstock (Vpj,) (Fig. 2). At the same time, the coil is relative to each other along the distance between the peripheral surface parallel to the axis of symmetry by the bone of the disk 6 and the workpiece 11 is equal to the cam.

The distance between peripheral one 11 is pressed against the prism 12. On the rod, the surface of the disk 6 and the workpiece 11 7 has divisions corresponding to 40 and the size b of the runaway disk 6 from the diameter of the saw blade 6. of preparation.

The device works as follows.

When clamping the workpiece 11, the movable part of the device 2 occupies a position corresponding to the diameter of the workpiece 11, the cam 1 at the same time moves with the clamping device 2 and occupies a position at which the distance between the working edges 3 and 4 in the direction of movement of the commander 8 cutting grandma 5 dl given
