Problems solved by technology

[0003] In the prior art, the step of grinding the sample is usually that the students themselves hold the cylindrical metal sample and put it on the rotating grinding disc, slowly grind it, and constantly observe the grinding condition of the surface, which often leads to problems, that is, The students hold the samples in their hands, but the grinding disc rotates very fast, and sometimes the samples may fly out of their hands, which is very dangerous to the students themselves and the surrounding environment; at the same time, the grinding is entirely dependent on manpower, which also reduces the workload. s efficiency

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 , 2 As shown, a device for grinding metallographic experimental samples includes a base 1, a grinding disc 6, a sample locking mechanism 4, and a water tank 7. A support rod 2 is arranged on the upper surface of the base 1, and the support rod 2 has two sections, which are respectively The vertical section of the vertical state, and the horizontal section of the horizontal state, the top of the vertical section is connected with the leftmost side of the horizontal section, and the elastic hard connecting rod 3 is fixedly connected to the bottom of the rightmost side of the horizontal section. The connecting rod 3 is an elastic material, which can change its shape and maintain its shape when it is not stressed;

[0018] The sample locking mechanism 4 is connected to the bottom of the elastic hard connecting rod 3. On the upper surface...

Abstract

The invention discloses a device for polishing a metallographic experimental sample. A support rod is arranged on the upper surface of a base, the support rod totally comprises two sections, the top end of a vertical section is connected with the leftmost side of a horizontal section, and an elastic hard connecting rod is fixedly connected to the bottom of the rightmost side of the horizontal section, and made of an elastic material, so that the shape of the elastic hard connecting rod can be changed and the form of the elastic hard connecting rod can be kept while not subjected to force; a sample locking mechanism is connected to the bottom of the elastic hard connecting rod, a circular groove is formed in the upper surface of the base and beside the support rod, a circular grinding discof which the diameter is smaller than that of the groove is arranged concentrically in the groove, and the grinding disc is driven to rotate through a motor; a water tank is arranged on the base, andthe water tank pumps cooling water out from the water tank through a water pump, and a water pipe is drained, thereby being capable of cooling the surface of the grinding disc. The safety of the sample using the device disclosed by the invention can be effectively improved, and the sample does not fly out; in addition, the polishing efficiency is further improved.

Description

technical field [0001] The invention relates to an experimental device, in particular to a device for grinding metallographic experimental samples. Background technique [0002] In the teaching of the heat treatment course, students need to be taught to observe the metallographic structure of the metal sample. To observe the metallographic structure, students need to grind the surface of the metal sample until the surface is smooth and then soak it in aqua regia for corrosion. [0003] In the prior art, the step of grinding the sample is usually that the students themselves hold the cylindrical metal sample and put it on the rotating grinding disc, slowly grind it, and constantly observe the grinding condition of the surface, which often leads to problems, that is, The students hold the samples in their hands, but the grinding disc rotates very fast, and sometimes the samples may fly out of their hands, which is very dangerous to the students themselves and the surrounding e...
