Surface machining method for sealing plug of crossed roller bearing

Abstract

The invention relates to the field of bearings, and particularly discloses a surface machining method for a sealing plug of a crossed roller bearing . According to the surface machining method, a finishing machine is adopted, wherein the finishing machine comprises a driving assembly, a supporting assembly and a pressing assembly; the driving assembly comprises a power module and a transmission module, the transmission module comprises a transmission rod, and one end of the transmission rod is an adapter end; the pressing assembly comprises a fixed base and a pressing rod, and one end of the pressing rod is an abutting end; during machining, a sealing plug to be machined is placed on the working surface, and a V-shaped notch of the sealing plug is aligned and matched with the adapter end of the transmission rod; the pressing rod is released, and the pressing rod and the transmission rod jointly press the sealing plug, so as to clamp the sealing plug; the power module works and drives the transmission rod and the sealing plug to rotate; and the surface of the sealing plug is machined through external grinding equipment. According to the surface machining method, the sealing plug can be efficiently and reliably clamped, and the machining efficiency is high.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a surface processing method for a plug of a crossed roller bearing. Background technique [0002] Crossed roller bearings are a kind of bearings with cross-arranged balls. Compared with conventional roller bearings, crossed roller bearings can bear loads in all directions. The pressure under the action is small, and it has good structural rigidity and structural stability. [0003] There are two assembly methods for crossed roller bearings, one of which divides the inner ring and / or outer ring and fixes them again after the rolling elements are assembled; the other assembly method is to open mounting holes for the inner ring and / or outer ring , the rolling body is loaded from the mounting hole, and after the assembly is completed, the sealing plug 11 is used for sealing, that is, as figure 1 and figure 2 form shown. [0004] Crossed roller bearings require high precision. For crossed...

AI Technical Summary

Problems solved by technology

There are multiple disassembly and assembly processes between the plug 11 and the bearing ring 1

[0005] During the installation of the plug, the problem of interference between the plug and the installation hole is often encountered, and it is difficult to assemble the plug. Due to the high requirements on the surface accuracy and installation accuracy of the plug, it is impossible to force the assembly

At this time, it is necessary to carry out surface processing on the plug, but because the size of the plug is too small, it is difficult to clamp and process.
