Deep groove ball bearing inner ring machining device and method

Abstract

The invention discloses a deep groove ball bearing inner ring machining device. The deep groove ball bearing inner ring machining device comprises a clamping mechanism, an inner grinding mechanism and an outer grinding mechanism, the clamping mechanism comprises a rotating cylinder, the rotating cylinder is rotationally connected with a first machine frame through a bearing, the rotating cylinder is connected with the output end of a first motor through a transmission mechanism, a plurality of chucks used for clamping workpieces are arranged at the left end of the rotating cylinder, the chucks are integrally in an arc shape, a first linear driving mechanism used for driving the chucks to move in the radial direction of the rotating cylinder is arranged on the rotating cylinder, the inner grinding mechanism comprises an inner grinding disc arranged in the interior of the rotating cylinder, the inner grinding disc and the rotating cylinder are coaxially arranged, a plurality of inner grinding heads are arranged on the periphery of the inner grinding disc, the outer faces of the inner grinding heads are arc faces, and a third linear driving mechanism used for driving the inner grinding heads to move in the radial direction of the inner grinding disc is arranged on the inner grinding disc. According to the device, a ball groove and an oil groove of the bearing inner ring workpiece are jointly ground through an internal and external double grinding method, internal and external pressure of the bearing inner ring workpiece can be balanced as far as possible through pressure control of the internal and external grinding heads, and abnormal deformation of machining of the outer circle face of the bearing inner ring workpiece is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, more specifically, it relates to a deep groove ball bearing inner ring processing device. Background technique [0002] There are many factors that cause bearing failure. According to relevant foreign statistics, bearing failure due to insufficient lubrication and improper lubrication account for about 37%, while bearing failure due to pollution accounts for about 21%. Therefore, adopting the correct oil supply arrangement and ensuring the cleanliness of the oil are one of the necessary means to ensure the stable and normal operation of the system. At present, the commonly used oil supply arrangement includes three structures, one is the side spray oil supply arrangement, the other is the impeller radial oil collector ring oil supply arrangement, and the other is the ordinary ring lubrication oil supply arrangement. Among them, ordinary under-ring lubrication and impeller radial oi...

Problems solved by technology

[0003] The invention provides a deep groove ball bearing inner ring processing device, which solves the problem in the related art that when the ball groove of the outer circular surface of the bearing inner ring is processed, the workpiece of the bearing inner ring is only subjected to force on one side, resulting in abnormal deformation beyond the processing requirements. technical problem
