Pneumatic type reinforcing machining equipment for machining bearing outer ring rolling way

Abstract

The invention discloses pneumatic type reinforcing machining equipment for machining a bearing outer ring rolling way. The pneumatic type reinforcing machining equipment comprises a reinforcing machining module and a grinding feed module. The grinding feed module comprises a high-pressure feed module. The reinforcing machining module comprises a machining box and a reinforcing machining mechanism.The reinforcing machining mechanism comprises a clamping mechanism and a peripheral jet mechanism. The peripheral jet mechanism comprises a peripheral nozzle and a rotary driving motor. The peripheral nozzle comprises a feed end and a distribution end. The distribution end is arranged in the center of a clamped bearing outer ring. An inner cavity of the feed end forms a feed channel. One end of the feed channel communicates with a tail end feed pipeline of the high-pressure feed module. The other end of the feed channel communicates with the distribution end. A plurality of jet channels are formed in the distribution end. The head ends of the jet channels communicate with the feed channel. The tail ends of the jet channels extend to the exterior of the distribution end. The reinforcing machining equipment can conduct reinforcing machining on the bearing outer ring rolling way and is especially suitable for machining an outer ring rolling way of a micro bearing.

Description

technical field [0001] The invention relates to a strengthening grinding processing device, in particular to a pneumatic strengthening processing equipment used for processing a bearing outer ring raceway. Background technique [0002] Bearings are the basic parts of most mechanical equipment, and also the support point of power and movement, which directly affects the running performance of the entire equipment and the realization of expected functions. Most of the bearings of high-end bearings are imported. According to the "Thirteenth Five-Year Plan", the state clearly proposes to focus on promoting my country's bearing manufacturing technology and quality level to adapt to the "four highs" (high precision, high speed, high load) of bearing applications. , high reliability) development requirements. Bearing damage will not only cause property damage, but may also lead to a large number of casualties, so it is of great significance to improve the bearing fatigue life. [0...

AI Technical Summary

Problems solved by technology

The damage of the bearing will not only cause property loss, but also may cause a large number of casualties, so it is of great significance to improve the fatigue life of the bearing

[0003] Existing intensified grinding machines can only perform intensified grinding on the raceway of the inner ring of the bearing. For example, the application publication number is CN104942664A, which discloses an intensified grinding machine for bearings. The workpiece is processed after mixing. This method cannot process the outer ring raceway of the bearing, especially the outer ring raceway of the miniature bearing.
