The invention relates to mechanical engineering and can be used in automatic systems of machine tools and is additional to authsv. No. 1137395.

The purpose of the invention is to expand the functionality.

FIG. 1 shows a schematic of the device, the total VTS, nafig. 2-view A nafig. 1, fig. 3 view of Bna of FIG. one .

A device for simultaneous control of several moving elements comprises a spring-loaded pivoting rod 2 installed in the housing 1 with the drivers 3 fixed on it, coupled with the pins 4 of the moving elements 5, a bracket 6 rigidly connected to one of the moving elements 5 and the spring 7 turning Datang 2 is installed between the bracket 6 and the leash 3, performed with two projections 8 and 9.

Each moving element 5 is provided with a spring-loaded pusher 11 and a hinged-lever part 12, whose swing axis 13 is located on the pusher 11, movably mounted in its axial bore 10, with the pin 4 of each moving element 5 rigidly mounted on its hinged-lever part 12.

The spring 7 passes through the axis of symmetry of the swivel rod 2 and turns the latter, and with it the leads .3 towards the hydraulic cylinders 15 all the way from the pins 4 into the protrusions 8 through vodka 3. The signal flag 18 turns with the rod 2 interacts with switch 20, which gives a signal. Details are clamped. If at least one workpiece 21 is missing at the machining position when clamping (Fig. 2), the corresponding pusher 11 under the action of the spring 22 protrudes beyond the clamping end 23 of the corresponding bracket 6. At the same time, the corresponding pivot lever pivots on the part 12 relative to the second axis 14, and pin 4 attached to it, resting against the protrusion 8 of the corresponding driver 3, prevents the full rotation of the rod 2 and, therefore, the flag 18, which is rigidly connected to Mr. 18, does not reach the end switch 20.

functionality by providing not only control of the end positions of the moving elements 5, but also the presence of blanks 21 in the machining positions.

It is operated with switches 19 and 20. Pushers 11 are mated with workpieces 21 of workpieces and preloaded by springs 22. Elements 5 are mated with workpieces 21 with their clamping ends 23.

The device works as follows.

In the initial position, the oil is fed into the cavities of the 17 hydraulic cylinders 15. The displacing elements 5 and the bracket 6 are extended. Under the action of the spring 7, the rod 2 and the drivers 3 are rotated from the hydraulic cylinders and contacts

After loading the blanks 21 to the machining position {and the pressure is applied to the cavities 16 of the hydraulic cylinders 15. The elements 5 and the bracket 6 move to the extreme right position (Fig. 3), the pushers 11, contacting the blanks 21, sink into the elements 5, turning the corresponding chip. the way the hinge part 12 relative to the axes of the swing 13 and 14.

The spring 7 passes through the axis of symmetry of the swivel rod 2 and turns the latter, and with it the leads .3 towards the hydraulic cylinders 15 all the way from the pins 4 into the ledges 8 of the leads 3. The signal flag 18, turning together with the rod 2, interacts with switch 20, which gives the signal details are clamped. If at least one workpiece 21 is not at the machining position when clamping (Fig. 2), the corresponding pusher 11 under the action of the spring 22 protrudes beyond the clamping end 23 of the corresponding bracket 6. At the same time, the corresponding pivot-lever part 12 rotates relative to the second axis 14, and the pin 4 fixed on it, resting against the protrusion 8 of the corresponding leash 3, prevents the rod 2 from turning completely, and consequently, the flag 18 rigidly connected with it does not reach the end switch 20.
