Portable semi-automatic grinding and polishing equipment

Abstract

The invention discloses portable semi-automatic grinding and polishing equipment which is used for carrying out grinding and polishing pretreatment on a test sample. The portable semi-automatic grinding and polishing equipment comprises a mounting base, a fixed device and a turnplate, wherein the turnplate is rotatably arranged on the mounting base, the fixed device consists of a stand, a manual regulating device and a clamping mechanism connected with the manual regulating device, the manual regulating device is arranged on the stand which is detachably arranged on the mounting base, the test sample is fixed by the clamping mechanism, the manual regulating device drives the clamping mechanism to drive the test sample to approach or be away from the turnplate, and the turnplate carries out grinding and polishing pretreatment on the test sample. the portable semi-automatic grinding and polishing equipment is simple in structure, simple and convenient to operate, small in occupied space, safe and stable, and capable of carrying out portable semi-automatic grinding and polishing, improves the test sample preparation efficiency and qualification, and increases the practicability.

Description

technical field [0001] The invention relates to the technical field of sample grinding and polishing equipment, in particular to a portable semi-automatic grinding and polishing equipment with simple structure and easy use. Background technique [0002] The rapid development of modern industry puts forward higher requirements for product quality. In order to ensure safety and profit, more and more products must undergo failure analysis and prevention. Grinding and polishing machines are often used in the failure analysis and testing of metal materials and components. The microstructure analysis or metallographic analysis can only be carried out after the sample is ground and polished before sample preparation, and the grinding and polishing machine is also suitable for electronic components. Samples are prepared for structural analysis of devices. Grinding and polishing the sample pre-treatment sample preparation is an important testing process, only the preparation of qual...

Problems solved by technology

[0004] However, after a long time of use, the automatic working head has high failure rate, low precision, poor grinding and polishing effect, and the prepared grinding and polishing surface is uneven, so it is impossible to prepare qualified samples; on the other hand, the designed automatic grinding and polishing machine only Automatic grinding and polishing of samples with regular shapes and fixed sizes cannot meet the market demand for diverse sample materials. For example, it is difficult to clamp small samples, the sample cannot be clamped firmly, and the automatic working head is easy to be damaged. Therefore, the practicability is limited. Restrictions; the price of automatic grinding and polishing machines is more than ten times the price of manual grinding and polishing machines, which cannot be widely used and cannot achieve the purpose of improving efficiency

The defects in the automatic grinding and polishing machine of the prior art are: 1, the sample is clamped with poor stability

2. The practicability of the equipment is not high

3. The qualified rate of the prepared samples is low
