Bearing ring channel ultra-fine grinding device

Abstract

The invention relates to a bearing ring channel ultra-fine grinding device, and relates to the technical field of bearing machining. The device comprises a base and a driving mechanism disposed on thebase, and the base is provided with a spindle box, a workpiece compaction device, a channel position adjustment sliding table and a pendulum shaft device. The driving mechanism is connected to and provides a power source for the spindle box and the pendulum shaft device, the spindle box is disposed opposite to the workpiece compaction device, and a to-be-machined bearing ring is disposed betweenthe spindle box and the workpiece compaction device. The pendulum shaft device is arranged on and fixedly connected with the upper surface of the channel position adjustment sliding table. One end ofthe pendulum shaft device is provided with an ultra-fine head provided with oilstone. The pendulum shaft device controls the ultra-fine head to swing. The ultra-fine head is located above the bearingring between the main shaft box and the workpiece compaction device and is used for machining the bearing ring. The channel position adjustment sliding table adjusts the relative position of the pendulum shaft device and the to-be-machined bearing ring. Machining of a bearing ring channel is more accurate through the ultra-fine head, and the machining quality of the bearing ring channel is improved.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a deep groove ball bearing ferrule channel superfinishing device with more precise control. Background technique [0002] Bearings are the most widely used components. The groove is the most important working surface of the bearing when it is running. Its shape accuracy and surface quality have an important impact on the bearing's running accuracy, life, vibration and noise performance. The groove is located on the surface of the deep groove ball bearing ring, its shape is a torus, and its axial section is a circular arc. [0003] Superfinishing is a traditional grinding process, referred to as superfinishing. The working method of superfinishing is to press the whetstone floatingly on the surface of the workpiece with a certain pressure and make small high-frequency oscillations. At the same time, the surface of the workpiece is fed relative to the whetstone. Super...

Problems solved by technology

[0004] The grinding of the groove of the deep groove ball bearing ring is generally carried out on a super-finishing machine. The structure of the existing super-finishing machine is complicated, the operation is inconvenient, and the machining accuracy is difficult to improve. Because the groove of the deep groove ball bearing ring The required accuracy is continuously improved, and the processing requirements for the ultra-finishing machine are also increased accordingly.
