Grinding device with controllable contact range for excircles of shafts

Abstract

The invention relates to the field of shaft grinding, in particular to a shaft outer circle grinding device with a controllable contact range, which comprises a clamping rotating device for transversely fixing a shaft workpiece and a multi-surface grinding device for synchronously grinding the end surface and the outer circle surface of the shaft workpiece, the multi-face grinding device is arranged on a second movable sliding table and comprises a frame body, a belt type grinding mechanism, a disc type grinding set and a surface attaching mechanism used for attaching the belt type grinding mechanism to the outer circle face of the shaft workpiece. According to the grinding device, the belt type grinding mechanism and the disc type grinding set are arranged, the belt type grinding mechanism is promoted to be attached to the outer circle face of the shaft workpiece through the surface attaching mechanism, the outer circle face and the step end face of the shaft workpiece are ground at the same time, the grinding effect on the shaft workpiece is improved, and the grinding precision is improved.

Description

technical field [0001] The invention relates to the field of shaft grinding, in particular to a grinding device with a controllable contact range of the outer circle of a shaft. Background technique [0002] At present, when grinding the outer surface of the shaft workpiece, it is not only necessary to process the outer surface, but also the end surface. For example, the stepped shaft has steps, and the surface of the steps needs to be ground. The traditional method is to place the grinding wheel obliquely, and the grinding wheel The outer circle is trimmed into a 90-degree profile, and the outer circle and end face are ground. In this way, the grinding wheel has a high stop and correction frequency, which reduces the work efficiency and the grinding accuracy is not good. [0003] The currently disclosed Chinese patent CN202121201088.5 is a shaft cylindrical grinding device, including a fuselage, a grinding disc, and a clamping assembly. A laterally movable worktable and a l...

Problems solved by technology

[0004] According to the above-mentioned patent, the patent grinds the outer circular surface and the step surface of the shaft workpiece by grinding the outer cylindrical grinding surface and the two end faces of the grinding ring, but the grinding ring of the patent and the shaft workpiece The contact area of ​​the surface is too small, resulting in poor grinding effect. Therefore, there is a need for a grinding device that can control the contact area with the shaft workpiece
