Description

Grinding and polishing clamping device

Technical Field

The invention relates to the field of grinding and polishing, in particular to a grinding and polishing clamping device.

Background

The model grinding and polishing technology is a very common surface treatment technology, surface retreatment is usually needed after model manufacturing and processing are completed, appearance roughness is caused by improper treatment, and even performance of the model is affected, so that grinding and polishing treatment needs to be carried out on the model.

The polishing machine plays a very important role in actual production and experiments, and particularly in the experimental stage, when a novel surface texture is processed, a processing surface needs to be polished and cleaned firstly.

The traditional polishing machine has the problems of low processing efficiency, lack of a matched sample clamping device, unstable processing precision and processing quality and the like.

The patent application No. 201810181749.9 discloses a clamping device for clamping a sample during polishing of a polishing machine, which comprises an upper base, a lower base, a reciprocating motion frame, a pressure spring supporting seat, a pressure spring supporting rod, a pressure spring pressing rod, a sleeve, a material storage box, a pressing cover guide rod, a driving hook and a clamping assembly; the extrusion of the grinding paste is controlled by utilizing the balance principle of the friction force borne by the sample and the spring force of the pressure spring, and when the friction force is decomposed and is greater than the spring force of the pressure spring, the lower base slides and finally drives the pressing cover to slide downwards, so that the grinding paste is extruded; when the friction force is decomposed and is smaller than the spring force, the pressure spring pushes the pressure spring compression rod to return and finally drives the compression cover to slide upwards, and therefore the grinding paste is stopped being extruded; the polishing disc is repeatedly circulated, so that a proper amount of grinding paste is always stored on the friction surface between the polishing disc and the sample, the sample is effectively, stably and firmly clamped during polishing, and the polishing precision and the polishing quality are improved.

The structure of the patent is complex, and how to utilize a simple device to realize effective, stable and firm clamping of the sample during polishing is the problem solved by the research of the application.
