Description

The invention of otnostis to metalworking, namely to the processing of holes with cutting and deforming pulling, with the imposition of longitudinal oscillations on the past. By OCHOBHOKV auth. St. № 742058 from BeckieH: cartridge for fastening the wires, equipped with a spring-loaded sleeve and a mechanism for fastening the wires, which are widened on the body, made in the form of a wedge and two shoulders lever, hinged in the sleeve flj The disadvantage of the well-known cartridge is the mounting process in the chuck of retraction of holes with superimposed oscillations on the spacing. The purpose of the invention is to automate the process of fastening the stretch. The goal is achieved by an end-to-end groove, the angle between the intersection of the planes of which is 20-160, FIG. 1 depicts a cartridge, OSNTIC VIEW, FIG. 2 - drawn from the tailings -. , one, made in the form of a truncated n g Ramida; on r. 3 - view B per g ,, 2; in fig. 4 shows section A-A in FIG. 2; in fig. 5 - section of the stop with a Y - shaped groove. The cartridge consists of a housing 1, on which a lashing lash 2 is seated, a spring in the axial direction with a return spring 3. In the longitudinal groove of the sleeve 2 there is a mechanism for pressing the campus axially in the axial direction, consisting of a flying lever 4 fixed on axis 5 in the sleeve 2 and one connected with one wedge b, and the second with the body of 1 cartridge. In the opening of the housing 1, the distance rings 7 and the stop 8 are installed with a V-shaped groove for accommodating: i the stem of broach 9, which is made in the form of a truncated taramida 10 in height, at the base of which lies a rectangle with a ratio a to b from 2s3 to 1: 3. On the ribs lying in the plane of one of the large garnias of the 1-1 pyramid, bevels 12 and 13 are made at an angle C to this face (from 30 to 60). The stop 8 is fixed relative to the body 1 of the cartridge and the wedge 6 of the mechanism for clamping the body to the body in axial alignment with the screw 14. A key 15, pressed into the body of the driver, fixes the position of the clamping sleeve. with respect to the body. Threaded

a part of the housing is screwed on the cover 16, which presses the return spring 3 and serves as a stop for the flexible sleeve. To reliably orient the spigot and to prevent it from being jammed in the V - shaped stop. Re 8 the angle between the intersecting planes 17 and 18 should be from 20 to 160.

The cartridge works as follows. At the end of the return stroke of the carriage of the stretching cup, the clamping sleeve 2 abuts against the end of the base plate of the machine tool or on a special stop mounted on the base plate and is displaced relative to the housing 1.

In this case, the clamping sleeve 2 will actuate the broken lever 4 of the clamp-lowering mechanism of the slide to the housing in the axial direction, the wedge 6 of which will take such a position that it will not interfere with the removal and installation of the slide into the opening of the housing 1. Thereafter 9 is installed in the opening of the housing 1 and under the action of the aperture-clamping carriage is pressed in axial direction to the stop 8 with a V-shaped groove installed and fixed by a screw 14 in the opening of the housing 1 Due to the interaction of one of the bevels 12 or 13, made under on a large H on one of the large faces 11 of the pyramidal part of the shank of the shank, with intersecting planes 17 and 18 forming a V-shaped groove in the stop 8, the pull-in shank is installed in the V-shaped groove of the stop 8 and takes a strictly oriented position relative to the body 1 the chuck and the wedge 6 of the mechanism for clamping the pulling to the body 1 in

axial direction irrespective of the initial position of the shank of the pulling in the opening of the housing 1. This position is adjusted by turning the stop 8 in the opening of the housing 1 so that the wedge 6 of the pressing mechanism of the pulling to the housing 1 in the axial direction can enter the groove made on the shank pulling and clamping the body axially. After that, the extension shank occupies a strictly oriented position relative to the body 1 of the cartridge and the wedge 6 of the mechanism for pressing the body to the body 1 in the axial direction, the carriage

5 long glass begins to make the labor movement. When this clamping sleeve 2 is moved to its original position under the action of the possibility of. gate spring 3 moves wedge 6

0 of the mechanism for pressing the body to the body 1 in the axial direction. Wedge 6 presses the broach against the anvil 8 in the axial direction, thereby carrying out a rigid fastening of the broach in the body 1 of the cartridge.

Formula of the invention

Cartridge for fastening the protector St. 742058, characterized in that, in order to automate the fastening process, the abutment is made with a V-shaped groove, the angle between the intersecting planes of which is 20-160.
