An anti-rotation plane is arranged on the long mandrel at one end of the boss of the cylinder.

And a tightening sleeve for assisting in mounting the part to be processed is arranged on the cylinder of the long mandrel.

The tightening sleeve is of a cylindrical structure, and the inner hole opening is of a conical structure, so that a part to be machined can be conveniently and rapidly introduced and tightened in the inner hole of the tightening sleeve. When the compression nut is screwed down, the open washer extrudes the part group to be processed to enter the inner hole of the tightening sleeve and tighten the part group to be processed, the compression nut is locked, and finally the tightening sleeve is taken out.

The opening gasket is a ring body with a semicircular inner hole and a groove formed in one side, and the groove is convenient for fast mounting and dismounting when a part to be processed is mounted and dismounted.

By adopting the technical scheme, compared with the prior art, the clamping device effectively solves the clamping problem in the process of grinding the excircle of the open bearing ring part, not only effectively improves the clamping efficiency, but also ensures that the clamping is firmer, the form and position tolerance is easier to control, and meanwhile, the quality is stable, thereby effectively improving the production efficiency.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The utility model relates to a grinding processing device of an outer circle of an open bearing ring, which comprises a long mandrel 1, wherein during manufacturing, a central hole 1.1 used for being installed on an outer circle grinding machine is respectively manufactured at two ends of the long mandrel 1, a cylinder 1.2 used for installing a part group 6 to be processed and consisting of parts 5 to be processed is simultaneously manufactured on the long mandrel 1, a boss 1.3 is manufactured at one end of the cylinder 1.2, a compression nut 3 is connected to the long mandrel 1 at the other end of the cylinder 1.2 through threads, and the part group 6 to be processed is pressed and held on the cylinder 1.2 of the long mandrel 1 through an open gasket 2 installed on the long mandrel 1 by the compression nut 3; in order to prevent the long mandrel 1 from naturally rotating and loosening when a part 5 to be processed is processed and installed, an anti-rotation plane 1.4 which is convenient to assemble and disassemble and is clamped into a chuck of a grinding machine to prevent the long mandrel 1 from rotating and loosening is manufactured on the long mandrel 1 at one end of a boss 1.3 of a cylinder 1.2; in order to more conveniently mount the part 5 to be processed and ensure the processing quality of the part to be processed, a tightening sleeve 4 for assisting in mounting the part 5 to be processed is manufactured on a cylinder 1.2 of the long mandrel 1 (note, if the tightening sleeve 4 is not provided, the part 5 to be processed is opened, so that a gap is not easy to tighten, and the processing quality is difficult to ensure), the tightening sleeve 4 can be manufactured into a cylindrical structure, and an inner orifice of the tightening sleeve is manufactured into a conical structure, so that the part to be processed can be rapidly introduced into and tightened in an inner hole of the tightening sleeve 4; the split washer 2 is made into a ring body with a semicircular inner hole and a groove formed in one side, the groove is convenient for fast assembling and disassembling when a part to be processed is assembled and disassembled, the split washer 2 is used for compressing a workpiece, and the opening (or the groove) is used for fast assembling and disassembling.
