Fluid abrasive finishing processing device and finishing method for tubular workpieces

Abstract

A fluid abrasive finishing device for tubular workpieces and a finishing method thereof, which belong to the technical field of parts inner surface polishing, and solve the technical problem that abrasives enter the gap between workpieces and fixtures. The device includes a frame, a hydraulic cylinder, a pusher For material cylinder and pipe workpiece fixture, guide rail is set on the right side of the upper surface of the frame, the left support frame is set above the left side of the frame, and the right support frame reciprocates horizontally along the guide rail; the lower hydraulic cylinder is fixed and installed on the horizontal direction On the frame below the right support frame, the pipe workpiece is clamped in the inner cavity of the pipe workpiece fixture, the left and right ends of the pipe workpiece fixture are oppositely provided with rubber pads, and the left end of the left rubber pad is installed on the left extrusion tube Among them, the left end of the right rubber pad is installed in the right extrusion pipe, the left end of the pipe workpiece is installed in the left rubber pad, and the right end of the pipe workpiece is installed in the right rubber pad. The invention can make all the abrasives enter into the pipe workpiece to be processed, the processing effect is obvious, and the end surface effect does not occur at both ends of the pipe workpiece.

Description

technical field [0001] The invention belongs to the technical field of inner surface polishing of parts, and in particular relates to a fluid abrasive finishing device and a finishing method for pipe workpieces. Background technique [0002] With the development of the manufacturing industry and the diversification of social needs, the demand for high-quality smooth surfaces of products is becoming more and more extensive, and the requirements for the effect of finishing parts are getting higher and higher. A large number of round tube parts, such as aero-engine fuel pipes and other thin round tube parts, have high finishing requirements for low-roughness and smooth surfaces in specific applications, especially the roughness value is required to be reduced to Ra0. 1 or less. Although electrolytic and chemical polishing methods can achieve lower surface roughness, serious environmental pollution and other problems make it difficult to use on a large scale. Therefore, it is u...
