Description

The invention relates to machine tool industry and can be used in the processing of parts such as shafts in fixed centers on grinding machines.

The purpose of the invention is to simplify the design.

Figure 1 shows a device with a lead part in the form of a spherical washer; in Fig.2 - section aa in Fig.1; in Fig.Z - section bB in Fig.1.

The automatic towing device comprises a stationary body 1, which is attached to the front headstock 2 of the grinding machine.

The fixed center A is inserted in the fixed spindle.

In the stationary housing 1 there are two longitudinal grooves G, and inside the housing there is a movable clamp 5 made in the form of a sleeve located in the bearings 6.

In the housing 1 there is a lead device in the form of a washer 7 with lead elements made in the form of fingers 8 located on the end face.

The clamp 5 contacts the spherical washer 7 and engages with a key 9 mounted on the rotary faceplate 10.

In the grooves of the clip are crackers 11,

A guide casing 12 is put on the fixed housing 1, which, with two bayonet grooves D, engages with the cylindrical part of the crackers 11 and is connected to them by nuts 13.

A drive 14 and a support 15 are fixedly mounted on the front headstock 2, with respect to which a lever 16 is pumped, connected to the drive rod 14 and the cylindrical parts of the crackers 11.

When processing parts 17 of small diameter, the drive elements can be made in the form of a collet 18,

The device operates in automatic mode as follows.

Part 17 is mounted on the fixed center 4 and is pressed by the tailstock of the grinding machine (not shown), while the clamp 5 is in the extreme

left provisions. After pressing the tailstock receives a signal to the drive 14 and the clamp 5 together with the casing 12 and the spherical washer 7 through the lever 16 moves to the right, capturing the part 17

end fingers 8 or collet clamp 18.

After that, a signal is supplied to the rotational drive of the faceplate 10. The faceplate 10 rotates, transmits by means of a key 9

rotation on the clamp 5, the driving element 8 or 18 and then on the workpiece 17.

Part 17 is released in reverse order.

The design of the proposed device can significantly simplify the design of the towing devices of this type, while there is a high reliability.

Claims (3)

1. An automatic towing device, in the housing of which there is a fixed center and a washer with towing Elements installed with the possibility of axial movement through the clamp and connected to the rotation drive, which is related to the fact that, with In order to simplify the design, the clamp is made in the form of a sleeve located in the bearings with rusks placed in its grooves, designed to communicate with the axial movement drive inserted into the device, which carries the lever system. 2. Device pop. 1, characterized in that the outer surface of the washer is made spherical, and the lead elements are in the form of fingers located on the end face. 3. The device according to claims 1 and 2, with the exception that the drive elements are made in the form of a collet. Fig.Z Editor Compiled by L. Vasiliev Tehred M. Morgenthal Corrector M. Keretsman
