Description

one

The invention relates to the processing of materials by cutting, in particular, to devices for securing parts to machine tools.

The aim of the invention is the expansion of technological capabilities by securing parts of various configurations through the use of a removable multi-faceted insert with a locking device.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 - a versatile interchangeable liner with a prismatic locking device; in fig. 4 - the same, side view; FIG. 5 is a multi-faceted, replaceable liner with a pin fixture; FIG. in fig. 6 - the same, side view; in fig. 7 - a many-sided replaceable insert with a U-shaped fixing device in the form of a bracket; in fig. 8 - the same, side view; in fig. 9 - device for fixing the l-shaped plate, general view; in fig. 10 is the same when fixing the bracket, a general view.

The clamping device comprises a power cylinder 1. At the end of the rod 2, the tip 3 is installed with the possibility of rotation around the rod 2 and moving along it. The swinging lever A is pivotally mounted on the tip 3 and the stand 5 located on the plate 6. The device has clamping elements. One clamping element is designed as pin 7, hinged

on the end of the free arm of the lever 1, and the other in the form of a removable multifaceted liner 8, provided with a locking element 9 and placed in the slot 10 can be rotated to the longitudinal axis of the plate 6.

The slot 10 is a multi-faceted hole made in the plate 6, partially closed at the bottom by two plates 11. The plate 6 has an arcuate groove 12 designed to rotate the stand 5 relative to the axis of the power drive through working discs 13. The clamping device 6 is attached to the machine table ( not shown). The metal 14 is machined with tool 15.

The device works as follows.

In the slot 10, the required replaceable insert 8 is installed, orienting it in such a way that the place of processing the part 14 laid in the element 9 is under the processing tool 15. In this case, the lever is directed so that pin 7 of the clamping part 14 does not interfere processing process. Then the power drive is turned on and the clamping force is transmitted from the power cylinder 1 by means of the tilting lever 4 through point 7 to the workpiece 14. The angle of the insert 8 relative to the longitudinal axis of the plate 6 is selected depending on the type of workpiece 14.
