Hydraulic semi-automatic constant-pressure grinding and polishing equipment

Abstract

The invention discloses hydraulic semi-automatic constant-pressure grinding and polishing equipment which is used for preliminarily grinding and polishing test samples and comprises a mounting seat, fixing devices and turntables. The turntables are rotationally arranged on the mounting seat, each fixing device comprises a support, a first driving device and a clamping mechanism connected with the driving device, both each first driving device and the corresponding clamping mechanism are mounted on the corresponding support, the supports are detachably arranged on the mounting seat, the test samples are fixedly clamped by the claming mechanisms, the first driving devices drive the clamping mechanisms to drive the test samples to approach to the turntables or leave away from the turntables, and the test samples are preliminarily ground and polished by the turntables. The hydraulic semi-automatic constant-pressure grinding and polishing equipment has the advantages that the hydraulic semi-automatic constant-pressure grinding and polishing equipment is simple in structure and small in occupied space, can be operated easily and conveniently and is safe, stable and portable, the test samples can be automatically ground and polished by the hydraulic semi-automatic constant-pressure grinding and polishing equipment, the test sample manufacturing efficiency and qualification can be improved, and the practicality of the hydraulic semi-automatic constant-pressure grinding and polishing equipment can be enhanced.

Description

technical field [0001] The invention relates to the technical field of sample grinding and polishing equipment, in particular to a hydraulic semi-automatic constant-pressure grinding and polishing equipment with simple structure, easy use, and portability, which realizes automatic grinding and polishing to prepare samples. 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 ...

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
