Abstract

The invention relates to a machine tool industry and can be used for fixing tools in a CNC metalworking machine shop, as well as in automatic machines in which a tool magazine moves in a loop with an actuating unit. The purpose of the invention is to increase reliability. When installing the tool holder 1 in the machine spindle 8, the magazine 3 moves towards the spindle, inserting the taper shank of the tool holder 1 into the hole of the spindle 8. Since the fingers 7 stop the movement of the sleeve 4, and hence the tool holder 1, the latter does not reach the stop in the cone 8 machine tool. Therefore, an axial movement of the tool holder in the direction of the spindle occurs by an amount equal to half the gap formed between the conical surfaces of the tool holder 1 and the cover 6, which is achieved by appropriate adjustment of the magazine stroke. 3 il.

FIG. 2

The invention relates to a machine tool industry and can be used for fixing tools in a CNC metalworking machine shop, as well as in automatic machines in which a tool magazine moves in a loop with an actuating unit.

The purpose of the invention is to increase reliability.

FIG. 1 shows the device, a general view (the tool is not installed in the spindle), a general view; in fig. 2 - the position of parts of the device in an intermediate position (the tool is installed in the spindle, but not clamped); in fig. 3 - the same, in the working position (the tool is installed in the spindle and clamped).

A multi-operation machine includes a tool fixture in a magazine. The fixture contains a tool holder 1 installed in the slot 2 of the magazine 3. The socket contains a sleeve 4, which is freely mounted in the opening of the magazine, and a fixed lid, which have conical surfaces which are mutually attached to each other.

The sleeve 4 at the end has evenly spaced grooves in which the springs 5 are placed, with the other end entering the similar grooves of the lid 6.

On the collar, the instrument holder 1 is tapered along a side, the sides of which correspond to the conical surfaces of the sleeve 4 and the socket 2, adjacent to them.

In the holes of the sleeve 4, evenly around the circumference, fingers 7 are mounted, which freely pass through the holes in the socket. When installing the tool holder 1, the fingers 7 abut against the fixed end 9 of the body of the headstock.

The device works as follows.

In the non-working position (Fig. 1), when the tool is not installed in the spindle 8, the tool holder 1 with its conical pivot rests against the conical height of the socket, and on the other hand under the action of the springs 5 is compressed by the conical surface of the movable sleeve 4.

When installing the tool holder 1 (Fig. 2) in the machine spindle 8, the magazine 3 moves towards the spindle, inserting the taper shank and tool holder 1 into the hole of the spindle 8. Fingers 7 abut against the end 9 of the spindle head body and, overcoming the force of the springs 5,

stop the movement of the sleeve 4 relative to the spindle 8, and with it the movement of the tool holder 1. A gap forms between the conical surface of the socket 2 and the conical surface adjacent to it of the tool holder 1. At this time, the magazine 3 stops (it is in its final position).

further, using a tool clamping mechanism (not shown), the tool holder 1 (FIG. 3) is clamped in the machine spindle 8. Since the fingers 7 stop the movement of the sleeve 4 and, therefore, the tool holder 1, the latter does not reach the stop in the cone of the spindle 8 of the machine. Therefore, there is an axial movement of the tool holder in the direction of the spindle by an amount equal to half the gap, which is formed between the conical

instrumental holder 1 and cover 4 surfaces, which is achieved by appropriate adjustment of the magazine stroke.

In this case, a gap is formed on both sides of the conical toolbar 1, completely freeing it from

store supports.
