SU1523255A1 - Arrangement for clamping sleeve - Google Patents

Abstract

The invention relates to a machine tool industry, in particular for fixing cylindrical moving parts such as sleeves, quilts, etc., and allows increasing the service life of the device and simplifying its design. The device consists of clamping elements placed in the bore of the housing 1 and made in the form of two wedge pairs consisting of conjugated inner 2 and outer 3 half-rings, each of which is formed by eccentrically arranged cylindrical surfaces of supporting strips that keep the inner 2 half-rings from sliding the surface of the sleeve 15, and the drive mechanism. Under the influence of the drive mechanism, the outer half rings enter the space between the bore of the case and the inner half rings, pressing them against the sleeve. 1 il.

The invention relates to a machine tool, Depending on the direction of rotation

in particular, clamping or unclamping takes place for fixing the cylindrical pens 14

moving parts such as sleeves, pinolgilz 15. When clamping threaded sleeves 9

and so on and 10 are removed from each other, and, as an effect of the invention, is an increase in the period of 5 at the surface of the slot on the axis 8, the service of the device and the simplification of it are confined to the outer semiring 3 between the destructions.

The drawing shows the device, the cross-section.

The device consists of two wedge pairs placed in the bore of the case 1, consisting of the inner (additional) half-rings 2 and the outer (main) half-rings 3. The outer surface A of the half-rings 3 is displaced relative to the inner

the point in the housing 1 and the inner semi-rings 2, which, being kept from sliding on the outer surface of the sleeve 15 through the axles 5 by the supporting bars 6 and 7, are displaced in the radial direction and clamping the sleeve 15 with their inner surface.

When unclamping sleeve 15 threaded

surface B by the amount of eccentricity; 15 bushes 9 and 10 approach each other and are affected by theta e. The outer surface B and the inner-opposite surface of the slot on

axis 8, the outer semicircles 3 are weakened, while the inner semicircles 2, the surface G of the semirings are also displaced relative to each other by the value of eccentricity e. The axis II of surface G coincides with the axis of surface A, and the axis II-II of surface B coincides with the axis of surface B. Surfaces B and C have the same radius R.

In the ram 4 half-rings 2 are mounted

Claims (1)

Invention Formula A device for clamping sleeves containing clamping elements placed axes 5 with the body bores entering the slots between 25 bore and slats 6 and 7 made in racks. Between the canals are semirings, the outer surface of the outer (main) semirings 3 inside the axle is eccentric relative to the inner axis 8, which interact with the surface, and the thickened the ends threaded bushings 9 and 10 with a variety of-mounted to move straightened and placed in the ras-. opposite to each other, characterized by the point of the housing 1. In the end holes 30 so that, in order to increase the service life of the sleeves 9 and 10, the studs 11 are inserted, the co-devices and simplify its design, Others with their other ends are included in the grooves with an additional pair covers 12. Sleeves 9 and 10 screwed half circles, the outer surface of which on the threaded cheeks of the drive shaft 13, which is offset relative to the inner surface of the end of which is fixed to the handle 14. by an eccentricity value equal to The device works as follows. 35, the magnitude of the eccentricity of the main half-turn. additional half-rings coincide with the axis of the outer surface of the main half-rings, and the inner surface of the main semi-circular movement of the drive shaft 13, which through the threaded necks transmits the translational movement of the threaded sleeves 9 and 10, which keeps from the wire 0 and the outer surface of the additional shafty 11, inserted into the slots of the roof 12. body semirings have the same radius and their axes coincide. the point in the housing 1 and the inner semi-rings 2, which, being kept from sliding on the outer surface of the sleeve 15 through the axles 5 by the supporting bars 6 and 7, are displaced in the radial direction and clamping the sleeve 15 with their inner surface. When unclamping sleeve 15 threaded 20 radially, unclamp sleeve 15. Invention Formula body semirings have the same radius and their axes coincide.
