Abstract

The invention provides a polishing clamp device for metallographic structure analysis and a working method of the polishing clamp device. The polishing clamp device comprises a base, a first connection piece, a second connection piece, a test sample clamping device and an outer shell, wherein the shell is arranged on the outer portion of the test sample clamping device. The base is fixed to a box body of a polishing machine, the first connection piece is fixedly connected with the base, one end of the second connection piece is movably connected with a first connection piece, the other end of the second connection piece is movably connected with the outer shell, and the test sample clamping device is arranged in the outer shell and connected with the outer shell. The device has the advantages that the polishing clamp device is adopted to replace manual operation, so that the work efficiency is greatly improved; positive pressure is stably and elastically provided through springs, so that the polishing test sample is stressed uniformly, the polished surface is balanced, and the polishing quality is improved; the problem about the design of a polishing clamp on the polishing machine is solved, and the polishing clamp device is convenient to disassemble and flexible to adjust.

Description

technical field [0001] The invention relates to the technical field of metallographic sample preparation, in particular to a metallographic structure analysis polishing jig device arranged on a polishing machine and a working method thereof. Background technique [0002] Metallographic sample preparation technology is an important link in the observation of the microstructure of metal materials. It is a basic skill for material researchers to prepare qualified metallographic samples quickly, conveniently and efficiently. At present, when materials researchers prepare metallographic samples, the researchers can still polish the samples by hand when the samples are large. If the samples are relatively small, it will take time and effort for the researchers to polish by hand and the polishing effect is not ideal. [0003] Usually, for small samples, metallographic samples are often prepared by mosaic method, which mainly inlays small samples on the lower surface of a regular cy...

Problems solved by technology

[0004] Although material researchers have invented a mechanical clamping metallographic polishing device, it is necessary to manually hold the metallographic polishing device for polishing during the polishing process, so the metallographic polishing fixture device only plays the role of fastening the sample and does not It cannot play the role of independent clamping. To complete the metallographic preparation, it is necessary to manually hold the metallographic polishing device with the sample.

Such a metallographic polishing clamping device needs to occupy the worker's time, and also makes the worker unable to leave to do other things during the polishing process, and because the polishing time is usually relatively long under normal circumstances, the person holding the polishing clamp is in a fatigued state , affecting the work efficiency of its staff

[0005] For the mosaic metallographic preparation of small samples, there are many domestic products with different structures, and most of them are manually operated fixtures. The installation and operation are more complicated, and the product design cost is high, but the ideal polishing effect cannot be achieved.

The design of the mechanical clamping metallographic polishing device of this kind of product has not achieved the purpose of simplicity, convenience and high efficiency, and the production efficiency is low, the force of the polishing process is uneven, and the safety performance is low.

Its main disadvantage is that the designed metallographic polishing device cannot operate independently, and it is necessary to manually hold the metallographic polishing fixture to complete the metallographic preparation
