Description

Workpiece clamp for polishing machine for polishing round step mirror surface

Technical Field

The utility model relates to a polishing equipment technical field specifically is a work piece holder for burnishing machine of circular step mirror surface of polishing.

Background

Polishing refers to a process of reducing the roughness of a workpiece surface by mechanical, chemical, or electrochemical actions to obtain a bright, flat surface. The method is to carry out modification processing on the surface of a workpiece by using a polishing tool and abrasive particles or other polishing media. Polishing does not improve the dimensional accuracy or geometric accuracy of the workpiece, but aims to obtain a smooth surface or a mirror surface gloss, and sometimes also serves to eliminate gloss (matting). Polishing wheels are commonly used as polishing tools. The polishing wheel is generally made of a laminate of a plurality of layers of canvas, felt or leather, both sides of which are clamped by metal disks, and the rim of which is coated with a polishing agent formed by uniformly mixing micro-powder abrasive and grease, etc. During polishing, a polishing wheel rotating at a high speed (the peripheral speed is more than 20 m/s) presses a workpiece, so that the abrasive material rolls and cuts the surface of the workpiece in a micro-scale manner, a bright processed surface is obtained, and the surface roughness can reach Ra0.63-0.01 microns generally; when a non-greasy matte polish is used, the shiny surface can be matted to improve appearance. When the bearing steel balls are produced in large scale, a roller polishing method is often adopted. The chemical polishing of steel parts can be used as a pretreatment process of protective and decorative electroplating and also can be used as a pretreatment process of chemical film formation such as phosphorization blue. If the paint is directly applied without electroplating or chemical film forming, the paint can be sprayed with amino varnish or acrylic varnish, and has better protective and decorative effects after being dried. If the paint is dipped in the antirust passivation water solution before the paint spraying, the corrosion resistance can be further improved. The workpiece needs to be fixed by using a clamp in the polishing process.

The traditional clamp is usually fixedly arranged at a certain position and cannot turn over a workpiece in the use process, so that the workpiece needs to be taken down from the clamp for fixing again when the workpiece needs to be turned over and polished, the clamp is troublesome, and a lot of dust is generated in the polishing process and floats in the air, so that the dust is easily sucked into a suction cavity by workers, and the damage to the body is great.
