A kind of brush type metal workpiece surface strengthening grinding processing equipment and method

Abstract

The invention discloses a brushing type metal workpiece surface intensive grinding processing equipment and method. The processing equipment includes a rotating clamping device, a mixing brushing device and a high-pressure spraying device. The mixing brushing device includes a mixing mechanism and a brushing mechanism. The brushing mechanism includes a brushing housing, a rotating wheel brush and a second rotating drive mechanism; the rotating wheel brush is rotatably connected in the brushing housing, and its outer surface is provided with bristles distributed along the circumference; The bottom of the inner cavity of the brush housing is provided with a material storage space, and the side wall of the inner cavity of the brushing housing is provided with an escape port for preventing the bristles from extending to the processing surface of the workpiece; the rotating wheel brush is located above the material storage space , the path through which the free ends of the bristles turn intersects with the storage space. The invention can not only ensure more uniform effect and better quality of the enhanced grinding process, but also prevent the pollution caused by the diffusion of abrasive materials in the working environment, and at the same time prevent the processed surface of the workpiece from being oxidized.

Description

technical field [0001] The invention relates to a metal workpiece surface strengthening processing device and method, in particular to a brushing type metal workpiece surface strengthening grinding processing device and method. Background technique [0002] In the 21st century, mechanical equipment has filled every aspect of human life, ranging from nanoscale motors to rocket planes that reach the sky. The fatigue life and reliability of mechanical equipment directly affect its safety performance. Even tiny cracks may lead to huge disasters and incalculable consequences. Therefore, it is of great significance to improve the fatigue strength and life of mechanical parts. [0003] In the prior art, some processing methods that use high-speed jet abrasive materials to impact workpieces are proposed. For example, the application for invention with the application publication number of CN101733707A proposes a new processing method for enhanced grinding. The target surface to be ...

AI Technical Summary

Problems solved by technology

[0005] 1. The mixing and distribution of steel balls, grinding powder and grinding liquid is uneven, which leads to the inability to continuously spray abrasives during processing, which affects the processing accuracy

[0006] 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

[0007] 3. The grinding powder is directly sprayed and released into the atmosphere, and the density of suspended particles in the processing area increases, which pollutes the environment and seriously affects the health of the operators. At the same time, this part of the grinding powder cannot be recycled, resulting in a decrease in the utilization rate of the grinding powder

[0008] 4. During processing, if the mixing ratio of the abrasive liquid is small, and it is accelerated to a high-speed state together with the mixed abrasive, it may not be able to adhere to the processing surface, so that the processing surface of the workpiece is directly exposed to the air, which may easily cause the processing surface to be damaged. Oxidation occurs, the surface strengthening layer is weakened, the processing efficiency is reduced, and the quality needs to be improved
