Hybrid reinforced grinding method for bearing machining

Abstract

The invention discloses a hybrid reinforced grinding method for bearing machining. The hybrid reinforced grinding method for bearing machining includes the following steps of 1) clamping a bearing tobe processed on an electromagnetic centerless clamp; 2) adjusting the position of a high-speed spray head so as to align the high-speed spray head with the machining surface of the bearing, and adjusting the position of a smearing head to enable bristles of the smearing head to adhere to the machining surface of the bearing; 3) starting the electromagnetic centerless clamp to drive the to-be-machined bearing to rotate; 4) starting a smearing device, and smearing reinforced grinding material on the machining surface of the bearing through a smearing nozzle; and (5) starting a high-pressure spraying device, spraying steel balls on the machining surface of the bearing at a high speed through the high-speed spray head, and directly impacting grinding powder by the high-speed steel balls, so that a reinforced grinding layer is formed on the surface of the bearing. According to the hybrid reinforced grinding method for bearing machining, the grinding material is uniformly distributed on themachining surface of the bearing in a smearing mode, and the reinforced grinding layer is processed on the surface of the bearing in a high-speed collision mode, so that the machining effect is good.

Description

technical field [0001] The invention relates to an intensified grinding method, in particular to a hybrid intensified grinding method for bearing processing. Background technique [0002] With the rapid development of modern industrial technology, all walks of life have higher and higher requirements for the safety, reliability and life of mechanical equipment, such as automobiles, robots, internal combustion engines, ships, metallurgical machinery, coal mining machinery, etc.; among them, bearings are indispensable. The rotating load-bearing body is widely used in modern machinery and equipment, and is called a mechanical joint by the machinery industry. The failure of bearings will not only cause property losses, but also may cause a large number of casualties, so improving the fatigue life of bearings is of great significance. [0003] Among them, some processing methods that use high-speed jet abrasive materials to impact workpieces are proposed in the prior art. For ex...

AI Technical Summary

Problems solved by technology

However, with the continuous improvement of quality and requirements, the above-mentioned intensified processing technology has the following deficiencies: 1. The mixing and distribution of steel balls, grinding powder and grinding liquid is uneven, resulting in the inability to continuously spray abrasives during processing, which affects the processing accuracy

2. The grinding powder is randomly distributed on the steel balls. When spraying, it cannot be guaranteed that the grinding powder is uniformly adhered in front of each impact point, which greatly affects the cutting performance, and also reduces the impact strength of the processing area, resulting in residual pressure. Reduced stress, reduced fatigue resistance
