Rotation body surface static pressure abrasive flow finishing machining device and machining method

Abstract

The invention belongs to the technical field of surface finishing, and particularly relates to a rotation body surface static pressure abrasive flow finishing machining device and machining method. The device comprises a box body, a feeding system used for supplying abrasive materials to the box body, a rotating device and a rack, the feeding system and the box body form a circulation loop through a feeding pipeline and a returning pipeline so that the box body conducts dead-corner-free and efficient finishing machining on the outer surface of a rotation body to be machined in an isostatic pressing pressure field through the adaptability of the flow abrasive materials to the shape, the bottom of the box body is detachably connected with a rotating device, the rotating device comprises a speed regulating motor and a rotating shaft, and an end part of the rotating shaft extends into the box body. According to the device, the defects that time and labor are consumed and the efficiency is low in the complex surface finishing machining process of a conventional rotation body workpiece are overcome.

Description

technical field [0001] The invention belongs to the technical field of surface finishing in mechanical processing, and in particular relates to a static pressure abrasive flow finishing device and a processing method for the surface of a rotating body. Background technique [0002] The existing mechanical manufacturing technology puts forward higher requirements. In many cases, it is necessary to finish the high-quality surface of the parts to meet their performance; for the surface of the rotating body with a regular shape, it is generally carried out by cylindrical grinding. Surface processing; when the configuration of the rotary surface is more complex, it is necessary to carry out precision grinding on the abrasive tool to adapt to the surface shape of the workpiece. On the one hand, it will increase the difficulty of processing and increase the cost. Abrasives that meet the needs cannot achieve the finishing effect on the rotating surface with more complex configuratio...
