Horseshoe-shaped part machining positioning device and machining method thereof

Abstract

The invention discloses a horseshoe-shaped part machining and positioning device and a machining method thereof. The clamping and positioning device comprises a clamp body, positioning pins, a clamping assembly, a pressing plate assembly and a positioning cover plate, wherein the clamp body is used for clamping a part, and a part cavity, fixing screw holes and positioning pin holes are formed in the clamp body; the positioning pins are vertically arranged in the corresponding positioning pin holes when the part is machined; the clamping assembly is used for clamping a to-be-machined part arrangement piece; the pressing plate assembly is used for fixing the clamp body and a machine tool; and the positioning cover plate is used for clamping and positioning the part arrangement piece when the appearance surface of the part is machined. According to the horseshoe-shaped part machining and positioning device and the machining method thereof, the part is reasonably analyzed, a tool clamp is designed, positioning and clamping are converted, the scientific and reasonable machining method is applied, the problem in production is solved, and the production efficiency is greatly improved; and resource allocation is optimized, the production cost is reduced, and the production period is ensured.

Description

technical field [0001] The invention relates to a processing method of a horseshoe-shaped part of military equipment. Background technique [0002] Such as figure 1 Shown is a horseshoe-shaped part of a certain type of military equipment, which is a microwave part with a large number and is arrayed on the antenna. The existing processing technology scheme adopts ordinary milling machine, wire cutting, hydraulic (mold), fitter and other technological processes. The four sides of the ordinary milling machine are milled to ensure the dimensions of the six sides, and the wire cutting processing is formed with a unilateral oil pressure margin. The production of hydraulic molds, from The initial mold design, process, material preparation, processing, assembly, mold trial, final hydraulic product, and finally fitter scribing and drilling. [0003] There are following defects in this processing technology: [0004] a. The surface roughness of the wire-cut forming parts is uneven,...

AI Technical Summary

Problems solved by technology

[0006] c. The precision of the fitter's manual scribing and punching is low, and it is easy to be out of tolerance and low in efficiency

[0007] The above overall process is complex, with low processing efficiency, long cycle time and high cost. At the same time, it involves the production of a complete set of molds, which has high cost and long cycle time, which has become a bottleneck affecting the production progress of the complete machine assembly.
