SU1207642A1 - Collet chuck - Google Patents

Description

The invention relates to metalworking and can be used to fix thin-walled parts on automatic lathes and lathe turning machines.

The purpose of the invention is to increase the reliability of fastening by providing uniform clamping force.

Fig, 1 shows the cartridge, a general view; FIG. 2 is a section A-A in FIG. one.

The collet chuck consists of a clamping collet 1 located inside the housing 2, a clamping element; 15 is shown to the left of the clamping collet I

it in the form of an elastic thin-walled sleeve 3, crimped in cross section and placed inside the clamping collet 1. The number of the corrugations of the sleeve is a multiple of the number of petals 4 of the clamping collet 1

and at least maybe six. From the end, the cartridge is closed with the cap 5. The separator 6 with longitudinal slits and petals bent outwards prevents the sleeve 3 from axial movement. Sleeve 3 may be filled with a hollow and filled with a plastic material, such as a hydroplastic. The sleeve 3 may be reinforced with an elastic material, such as rubber.

The cartridge works as follows.

When driving drive t gi Sne

also moves to the left. Interacting with the cone of the housing 1, the clamping collet 1 moves in the radial direction and through the sleeve 3 fastens the thin-walled part 7.
