Abstract

The invention relates to mechanical engineering and can be used to fasten bush-like parts on circular grinding machines. The aim of the invention is to increase reliability. Item 15 is installed on the split part of the elastic sleeve 11, the flange 10 of which is located in the housing 7, and the sleeve itself is mounted on the conical part of the fixed center 1 and connected to the housing 7 by means of a finger 12 placed on the blind end of the housing, while the diameter of the flange of the elastic sleeve 11 less than the diameter of the cylindrical part of the fixed center 1. After installation of the part 15, the movable center 16 is moved to the left, while the elastic sleeve 11 is centered, sliding toward the cone of the fixed center, and its cut part is unclamping, clamping the part. 1 il.

The invention relates to mechanical engineering and can be used to fasten bush-like parts on circular grinding machines.

The purpose of the invention is to increase reliability.

The drawing shows the device, the axial section.

On the fixed center 1 there is a supporting sleeve 2 with a collar 3 and a screw 4, on which bearings 5 are mounted, which are retained from axial displacement by retaining rings 6. On the outer rings of the bearings there is a device case 7. The bearings are closed with a protective washer 8 and locked with a retaining ring 9. The inner end of the housing 7 has the ability to contact the flange 10 of an elastic sleeve 11 mounted on the conical part of the fixed center 1. The flange 10 of the elastic sleeve 11 is placed inside the body 7 and connected by means of a finger 12 mounted at the blind end of the housing entering the groove of the said flange with the housing 7, the flange diameter being less than the diameter of the cylindrical part of the fixed center 1. On the outer surface of the housing 7, there is a lead finger 13, with the same finger 14, which is screwed into the threaded hole of the machine's face plate. On the split part of the elastic sleeve 11, the workpiece 15 is placed, and in the center hole of the split part a cone of the moving center 16 enters.

Driving device works as follows.

The movable center 16 is retracted to the right, the part 15 is mounted on the sleeve 11, then the moving center 16 is moved to the left, while its cone enters the center hole of the split part of the sleeve 11, leads the axis of the latter to

The Q line of the machine centers, the thrust sleeve 11 itself thrust onto the center 1 cone and its flange retracts from the blind end of the body 7, at the same time the part of the elastic sleeve 11 expands and secures part 15. At the end of processing, the moving center moves to the center cone 1 and rests against the flange 10 on the end of the housing 7, with this, the volume of the sleeve is compressed, allowing the processed part to be removed.

Claims (1)

Invention Formula 5. A driver device comprising a housing located on a fixed center and a driver element, characterized in that, in order to increase reliability, the driver element is designed as an elastic sleeve installed axially on the conical part of the center, the flange of which is designed to interact with the inner end of the case and connected with it by a finger inserted into the device, wherein the diameter of the sleeve flange is smaller than the diameter of the cylindrical part of the center. 0 0 five
