Problems solved by technology

[0003] The purpose of the present invention is to solve the complex structure, inconvenient adjustment, small use range and high cost of the existing metallographic sample fixture, as well as the manual grinding and polishing of the metallographic sample, the finger is easy to be injured, the sample is polished, and the polishing quality is not good. Guaranteed, the sample is easy to fly out during the grinding process and the processing efficiency is low. An adjustable metallographic sample fixture is designed, which can effectively prevent the damage of the sandpaper opponent and greatly improve the processing efficiency. It is also easy to operate, easy to adjust, and easy to use. Wide range and low cost

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as Figure 1-3 shown.

[0020] An adjustable metallographic sample fixture, which includes a left upper splint 1, a left lower splint 2, a right upper splint 3 and a right lower splint 4, between the left lower splint 2 and the left upper splint 1, between the right lower splint 4 and the right upper splint 3 and The upper left splint 1 and the upper right splint 3 are all inserted into each other and then connected by rivets 8 so as to realize the relative rotation between the two; The tension spring 7; the ends of the left lower splint 2 and the right lower splint 4 have an outwardly protruding arc structure 10, and extra fingers can be placed on it when the sample is polished and polished. For long-term grinding and polishing work Can greatly reduce hand fatigue, more in line with the concept of ergonomics, more humane. In addition, th...

Abstract

An adjustable metallographic sample clamp comprises an upper left clamping board (1), a lower left clamping board (2), an upper right clamping board (3) and a lower right clamping board (4); the lower left clamping board (2) and the upper left clamping board (1) are connected through a rivet (8); the lower right clamping board (4) and the upper right clamping board (3) are connected through a rivet (8); the upper left clamping board (1) and the upper right clamping board (3) are connected through a rivet (8); a tension spring (7) is arranged between the lower left clamping board (2) and the lower right clamping board (4); an adjusting board (5) is installed on the lower left clamping board (2) and the lower right clamping board (4) through a T-type groove and can move up and down in the T-type groove; a pressure board (6) is arranged on the adjusting board (5); and force of fingers is evenly transmitted to the adjusting board (5) through the pressure board (6), so that the surface of a sample is stressed evenly. The adjustable metallographic sample clamp is simple in structure, convenient to operate, easy to adjust, high in work efficiency and low in cost.

Description

technical field [0001] The invention relates to an adjustable metallographic sample clamp, in particular to an auxiliary metallographic sample clamping mechanism for preparing a metallographic sample, which belongs to the field of mechanical engineering. Background technique [0002] Metallographic analysis is one of the main means of experimental research on metal materials, and the reliability and accuracy of experimental results largely depend on the quality of metallographic sample preparation. At this stage, there are mainly three methods for the preparation of metallographic samples: ① Hold the sample directly by hand to grind and polish it on sandpaper and a polishing machine, but this method has problems for small samples. The problem that the fingers are easily scratched by the sandpaper when the sample is polished, has caused certain injuries to the person, and the sample will be crooked due to the uneven force of the fingers, which cannot ensure the surface qualit...
