Abstract

TOOL STORE, containing a disk with sockets for tool holders, in which each socket is equipped with a spring-loaded cam covering the collar of the mandrel, and two clamps installed with the ability to interact with key grooves on the backing of the armature, characterized in that, in order to improve reliability By reducing the wear of the retainers, the cam is placed between the retainers with the possibility of blocking the exit of the retainers from the disc when the Mandrel is removed.

Description

 .one

FIELD: machine tool industry.

The aim of the invention is to increase the reliability of the shop by reducing the wear of the retainers interacting with the key grooves of the collar of the tool holder.

FIG. 1 shows a schematic of a tool magazine, a general view; in fig. 2 - tool magazine slot with mandrel; fig.Z - the same, without mandrel; in fig. A - section A-A in FIG. 2; in fig. 5 is a section BB in FIG. 3

The tool magazine contains a disk I with sockets 2 for tool holders 3. Each socket 2 is equipped with a spring-loaded cam 4 and two clamps 5 that enter key slots on the collar of the mandrel 3. Clamps 5 can be recessed by spindle keys 6 in slot 7 of the disk. The retainers 5 are pressed by the springs 9. The retainers 5 are held by turning the parts 10.

The cams 4 are pressed by the springs 1 and can be shifted along the groove, 12 up to the stop 13..

Tool shop works as follows.

If mandrel 3 is installed in slot 2, clamps 5 are inserted into the key grooves on the mandrel shoulder under the action of springs 9. Cam 4 covers mandrel shoulder 3. Springs 11 through cam 4 press the surface of mandrel slots to clamps 5, ensuring reliable and accurate mounting of mandrel in the nest shop.

When the mandrel is removed, the spindle 7 slides over the cone of the mandrel 3. In this case, the keys 6 of the spier 7 will enter

keyways on the collar of the mandrel and insert the retainers 5 into the recesses 8 of the disc, pressing the spring 9. The spindle 7 clamps the cone of the mandrel 3 and freely pulls it out of the slot by a horizontal stroke. When the mandrel 3 leaves the slot 2, the cam 4 moves to the right under the action of the spring 9 along the groove 12 up to the stop 13 and blocks the output of the latches 5 from the recesses 8 of the disc). In this position, the clips 5 remain as long as the socket is empty.

When the mandrel is inserted into the socket, the cam 4 covers the shoulders of the mandrel 3 and moves together with the mandrel to align the axis of the mandrel with the axis of the socket. When the cam 4 moves to the left, the output for the clips 5 from the recesses 8 of the disc is released. Under the action of the springs 9, the clips 5 are inserted into the key grooves on the collar of the mandrel when they are released by the keys 6 of the spindle 7. The tool is fixed in the socket.

The advantages of the proposed device are in reducing the wear of the clamps due to the fact that each time the mandrel is inserted into the tool magazine slot, friction of the locking surfaces of the mandrel of the mandrel is prevented when they are inserted. With this, the wear of the spring is reduced, since with each change of tool one cycle of expansion - compression is eliminated. This is achieved due to the fact that the cuff is located between two latches with the possibility of blocking the exit of the latches from the recesses of the disk when the instrument is removed and the latches remain recessed while the socket is empty.
