Metallographic phase grinding sample pressure adjusting device and metallographic phase grinding and polishing device and method

Abstract

The invention relates to the technical field of metallographic phase grinding, in particular to a metallographic phase grinding sample pressure adjusting device and a metallographic phase grinding and polishing device and method. The metallographic phase grinding sample pressure adjusting device comprises a fixed rod, a rotary connection rod and a sample clamping mechanism which are all sequentially connected; the sample clamping mechanism comprises an adjusting sleeve, a pin shaft arranged in the adjusting sleeve, a fastener installed at the upper end of the pin shaft, a spring arranged on the pin shaft in a sleeving manner and pressed in the adjusting sleeve through the pin shaft, and a sample clamping sleeve detachably installed at the lower end of the pin shaft and used for clamping a metallographic phase sample. The metallographic phase grinding and polishing device comprises the metallographic phase grinding sample pressure adjusting device, a cushion plate, a grinding and polishing disk and a motor. During grinding and polishing, firstly, pressure is preset, and then by adjusting the fastener of the pin shaft to be connected with the adjusting sleeve, the pressure is loaded onto the metallographic phase sample. According to the metallographic phase grinding sample pressure adjusting device and the metallographic phase grinding and polishing device and method, one or more metallographic phase samples can be pre-ground and polished on the same equipment, and pressure acting on the samples is adjustable and can be automatically released.

Description

technical field [0001] The invention relates to the technical field of metallographic grinding, in particular to a metallographic grinding sample pressure regulator, metallographic grinding and polishing equipment and a grinding and polishing method. Background technique [0002] During the development and research of metal materials such as steel and non-ferrous alloys, it is usually necessary to observe and analyze the microstructure of the material. The first thing to be completed is the sample acquisition-grinding-polishing-corrosion process. Whether a metallographic sample with a smooth surface and a qualified corrosion can be obtained directly determines the accuracy of material analysis. At the same time, in an actual study of metal structure and properties, it is necessary to grind and polish as many as hundreds or even more metallographic samples, especially for hard quenched steel, nickel-based alloys or soft magnesium alloys, aluminum alloys, etc. For non-ferrous...

Problems solved by technology

This method of sample preparation is difficult to adapt to today's large amount of practical research with high sample preparation requirements

However, although the new automatic grinding and polishing equipment can achieve efficient and fast sample preparation, the equipment is expensive, and it takes tens to hundreds of yuan to prepare a sample, so it is difficult to promote and use it in large quantities in enterprises and general universities.
