Tubular workpiece fluid abrasive finishing device and finishing method thereof

Abstract

The invention relates to a tubular workpiece fluid abrasive finishing device and a finishing method thereof, belongs to the technical field of part inner surface polishing, and solves the technical problem that abrasive enters a gap between a workpiece and a clamp. The device comprises a rack, a hydraulic cylinder, a pushing cylinder and a tubular workpiece clamp, and a guide rail is arranged on the right side of the upper surface of the rack; a left supporting frame is arranged above the left side of the rack, a right supporting frame horizontally reciprocates along the guide rail, and a lower hydraulic cylinder is fixedly installed on the rack below the right supporting frame in the horizontal direction; and a tubular workpiece is clamped in an inner cavity of the tubular workpiece clamp, rubber pads are oppositely arranged at the left end and the right end of the tubular workpiece clamp, the left end of the left rubber pad is installed in a left material extruding pipe, the left endof the right rubber pad is installed in a right material extruding pipe, the left end of the tubular workpiece is installed in the left rubber pad, and the right end of the tubular workpiece is installed in the right rubber pad. According to the device, all grinding materials can enter a to-be-machined tubular workpiece, the machining effect is obvious, and the end face effect cannot be generatedat the two ends of the tubular 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...
