Longitudinal polishing equipment for shaft parts

Abstract

The invention provides longitudinal polishing equipment for shaft parts. The equipment is a platform for the longitudinal automatic polishing of the shaft parts. The longitudinal polishing equipment comprises a worktable, a tailstock guide rail, a clamping chuck, a workpiece, a detection device, a tailstock, a moving mechanism, a polishing belt motor, a protective shield, a polishing feed motor, apolishing belt, a feeding guide rail, a detection device driving motor and a main shaft driving motor. The longitudinal polishing equipment for rod pieces, provided by the invention, is used for thelongitudinal polishing of the rod pieces, and improves the surface accuracy of the rod pieces. Main components are arranged on the worktable. The equipment is provided with the protective shield; theworkpiece is fixed to a work position through the clamping chuck and the tailstock; the detection device reciprocates and scans the workpiece for generating a processing start position; after polishing once, the position of the polishing belt changes once; the polishing feed motor is used for controlling the polishing feed rate; and after polishing once, the polishing belt returns, and the processing position of the workpiece changes for polishing until the entire workpiece is polished. The longitudinal polishing equipment can realize the automatic polishing of the surfaces of the shaft parts.

Description

technical field [0001] The patent of the invention belongs to the technical field of automatic surface finishing of shaft parts, and in particular relates to a longitudinal polishing equipment for shaft parts. Background technique [0002] Surface polishing of shaft parts refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and flat surface. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but for the purpose of obtaining a smooth surface or mirror luster, and can also improve the mechanical properties of the surface of shaft parts. [0003] The mechanical tensile rod test is mainly used to determine many important mechanical properties such as elasticity, strength, plasticity, strain hardening and toughness of the material. The surface quality of the tensile test piece is very strict, and the surface of the tensile rod needs t...

Problems solved by technology

At present, the polishing treatment of the surface of the stretching rod is mainly done manually. The work intensity is high, and there are harmful inhalants such as dust in the working environment. The quality of manual polishing depends on the experience of the workers, and the quality is difficult to guarantee.
