Flip-type sample clamping device for metallographic grinding and polishing machine

Abstract

The utility model relates to a flip-type sample clamping device of a metallographic grinding and polishing machine. The composition of the device includes: an overturn frame, a slideway shaft, a slideway pin, a shaft support, a balance weight, a baffle, a lock piece, a lock pin, a clamping nut and a sample holder; the overturn frame is composed of a flip plate and a shaft sleeve It is welded; the slideway shaft is a horizontally arranged fixed shaft for installing the overturning frame; the slideway pin is a standard set screw with a cylindrical end, which is installed in the threaded hole in the middle of the overturning frame; the balance weight is a cuboid , installed on the rear of the flip frame; the sample frame is welded by threaded rods and fixture plates, and is installed at the front long hole of the flip frame. The fixture plate is disc-shaped and welded on the lower part of the threaded rods , for mounting the specimen. The structure of the device is simple, without changing the structure of the original grinding and polishing machine, and both columnar and plate-shaped samples can be conveniently clamped; moreover, during the grinding and polishing process, the state of the grinding and polishing surface of the sample can be observed by turning over the device. No need to disassemble the sample.

Description

technical field [0001] The invention relates to a sample clamping device which can be added to an ordinary metallographic grinding and polishing machine. Background technique [0002] The ordinary metallographic grinding and polishing machine uses the motor to drive the grinding and polishing disc to rotate to grind the sample, which has the advantages of simple structure, low manufacturing cost and long service life. However, the sample clamping of ordinary metallographic grinding and polishing machines requires manual operation of holding the sample for a long time, which is labor-intensive and low in sample preparation efficiency, and the high-speed grinding and polishing disc is easy to fly the sample and hurt people, posing a safety hazard. [0003] In recent years, some sample holding devices for metallographic grinding and polishing machines have been developed at home and abroad. However, these sample holding devices have some disadvantages, for example: some device...

AI Technical Summary

Problems solved by technology

However, these sample holding devices have some disadvantages, for example: some devices have complex structure and high manufacturing cost; Holds standard cylindrical specimens, the shape of the specimen is limited

Moreover, when the sample holding device of most metallographic grinding and polishing machines needs to observe the grinding and polishing effect of the sample during the grinding and polishing process, the sample can only be disassembled to observe the state of the grinding and polishing surface, and then reinstalled to continue grinding and polishing , very troublesome
