Abstract

SUMMARY OF THE INVENTION: The device comprises a housing, a rubbing element 11, a collet for clamping a tool 5, made with a threaded shank, and a plunger 2, made in the form of a sleeve. Moreover, not a threaded shank mounted nut 10, abutting with the bottom of the sleeve. 2 Il.

Description

The invention relates to a friction-mechanical coating. ''

The aim of the invention is to simplify the design.

In FIG. 1 shows a device for fractional-mechanical coating, general view; in FIG. 2 - also, a section.

The proposed device includes a housing 1, which houses a piston 2 with a sleeve 3 and a spring 4. The plunger 2 has the ability to move freely along the housing 1. Inside the sleeve 3 is a collet 5 with a threaded shank. Collet 5 has the ability to move freely along the sleeve 3 under the influence of a nut 6 screwed onto the shank. The pin 7 prevents rotation of the collet 5 relative to the sleeve 3, and the key 8 is prevented from turning the plunger 2 relative to the housing 1. Risks 9 are applied to the housing 4 and the key 8 to determine the compression force of the spring 4. To regulate the preliminary compression of the spring 4, the bottom of the housing 1 is made in the form nuts 10. Tool 11, representing a wire of unlimited length, is inserted into the hole of the collet 5 from the side of the opposite workpiece 12. To facilitate the use of the device, the nut 6 can be equipped with a handle 13. The bottom of the sleeve 14 dnaznacheno also for the extraction nut 6 during disassembly and installation at its assembly.

The device is used as follows.

After fixing the device to the tool holder of the lathe, turning the nut 6, screw the sleeve 3 inside. In this case, the collet is opened and tool 11 is inserted into its hole 5 so that its front part protrudes 3 ... 6 mm beyond the collet 5, after which nut 6 is rotated in the opposite direction. Bearing in the bottom of the sleeve 14, it moves the collet 5 towards the plunger 10 ra, as a result of which the tool 11 is jammed. Then the device is led to the rotating part 12 until the compression of the spring provides the required pressure of the tool 11 on the part 15 12, which is controlled by risks 8. After wear of the protruding part of the tool 11, the device is removed from the part 12, unclench the collet and move the tool to the part, providing its desired protrusion 20 above the collet. Clamping the tool in the collet, continue the coating process.

Using the proposed device simplifies the design and expands its scope.
