Description

The invention relates to mechanical engineering, mainly metalworking, and can be used in devices for fastening workpieces to metal cutting machines.

The aim of the invention is to expand technological capabilities by increasing the range of sizes of blanks without increasing the dimensions of the device in height.

Figure 1 shows a device for fixing blanks, a General view; figure 2 - a view of figure 1; in Fig.3 - view B in Fig.1;

The device for securing the workpieces contains a rack 1 connected by a threaded connection to the bolt 2. The head of the bolt 2 is designed to interact with the movable cap

3. Rusk 4 is designed to attach the device to a device (not shown). On the cap 3 there are protrusions arranged to each other at an angle of 120 ° and distributed over the height of the cap 3 with a step equal to the course of the latter.

The device operates as follows.

A workpiece (not shown) is installed under one of the protrusions of the movable cap, and when the clamping bolt 2 is rotated, the movable cap 3 moves axially and clamps the workpiece to the surface at 5.

The increase in the control range without increasing the overall height of the device is ensured by stepwise arranged and deployed at an angle of 120 ° relative to each other protrusions, i.e., the use of the proposed device allows to expand its technological capabilities.

Claims (3)

1 1 The invention relates to mastic-building, mainly metalworking, and can be used in devices for fixing workpieces on metal-cutting machines. The aim of the invention is the expansion of technological capabilities by increasing the range of sizes of blanks without increasing the size of the device in height. Figure 1 shows a device for securing blanks, a view; figure 2 is a view of And figure 1; on fig.Z - view B in figure 1; A tool for securing the boot contains a stand 1 connected by a threaded connection with a bolt 2. The head of the bolt 2 is designed to interact with the movable cap 3. Rusk 4 is designed to attach the device to a device (not shown). On the cap 3, the protrusions are arranged, which are located to each other at an angle of 120 ° and distributed along the height of the cap 3 with a step equal to the course of the latter. The device works in the following way. A blank (not shown) is placed under one of the protrusions of the MOVING 6 cap and while rotating; With the pressing bolt 2, the movable cap 3 moves in the axial direction and clamps the blank to the surface of the fixture. Increasing the range of adjustment without increasing the overall height of the device is ensured by staggered protrusions arranged and turned at an angle of 120 relative to each other, i.e., the use of the proposed device allows to expand its technological capabilities. Claims An apparatus for securing blanks, comprising a stand with a clamping bolt and a movable cap with a protrusion, characterized in that, in order to expand technological capabilities by increasing the range of sizes of fixed blanks without increasing the overall dimensions of the device in height, two additional protrusions are made on the cap, and protrusions are located to each other at an angle of 120 ° and distributed over the height of the cap with a step equal to the course of the latter.
