A new patent from Dalian Best Bearing: surface grinder that enhances the positioning stability of bearing processing

Dalian Best Bearing Co., Ltd. has obtained a patent authorization entitled “A surface grinder for bearings that is easy to position”, the patent number is CN 221774093 U, and the application time is December 2023.

The patent abstract states that this new technology relates to a surface grinder for bearing processing, in particular, a device capable of simplifying the positioning process. The device includes a basic workbench, on which a positioning system is installed, the system comprising an integrated clamping module and an outer ring positioning module. The integrated clamping module consists of a suspension plate, which is connected to a support structure, on which a stabilizing fastening element is mounted, and the stabilizing fastening element is connected to a telescopic rod, on which a connecting sleeve is mounted, and an articulated shaft is mounted in the connecting sleeve, and a symmetrically arranged limit pressure block is provided at each end of the articulated shaft.


This invention uses the action of the telescopic rod in the integrated clamping module to make the two limit clamps open outward and press downward, thereby fully fixing the bearing placed on the workbench in the vertical direction. In this way, the grinding operation on the outer surface of the bearing can be completed in cooperation with the grinding assembly, improving the stability of the bearing positioning, preventing the position of the bearing from changing during the processing, and ensuring the safety and smoothness of the processing process.
