Description

A metallographic sample polishing equipment

technical field

The utility model relates to the technical field of sample polishing, in particular to a metallographic sample polishing device.

Background technique

In order to observe the metallographic structure, we usually firstly polish the metal and then polish it to prepare the metallographic sample. At present, the commonly used grinding and polishing means are mainly to manually grind on different types of sandpaper in sequence, and then use gauze on a polishing machine to polish. When using sandpaper for manual polishing of the sample, it is often easy to cause the sample to be worn out; , there will be a situation where the sample flies out; in addition, manual grinding of samples, at most two at a time, is inefficient.

Utility model content

The purpose of this utility model is to provide a metallographic sample polishing equipment, which can be installed with several different types of sandpaper, can perform polishing operations on several samples at the same time, and mechanically clamp the samples to avoid the appearance of the samples. The situation of grinding deviation improves work efficiency.

In order to achieve the above purpose, the utility model provides the following technical solutions: a metallographic sample polishing equipment, including: a shell, a polishing disc, parallel guide rails, characterized in that: there is a grinding work position on the shell, and a test The sample placement slot; the grinding disc is divided into several concentric square discs; the parallel guide rails are connected at both ends of the shell, and the position can be adjusted perpendicular to the direction of the shell; a spring is connected between the sample sliding link and the sample fixture; The specimen holder is equipped with screws above.

The beneficial effects of the utility model are as follows: there are several sandpapers of different types on one grinding disc, and the grinding operation can be carried out at the same time; at the same time, as the grinding progresses, the sample becomes smaller, and the spring can automatically give the loading force, which avoids the grinding of the sample. It is free from the sandpaper surface; in addition, it is also equipped with a sample holder to ensure the flatness of the sample during the grinding process.

detailed description

In order to better understand the utility model, below in conjunction with accompanying drawing and embodiment, specific embodiment is described in further detail, referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 and 4; Metallographic sample of the present utility model Polishing equipment, including a housing 1, a grinding disc 2, a parallel guide rail 3, etc. The housing 1 is provided with a sample placement groove 6, and the position of the parallel guide rail 3 is adjusted so that each sliding guide rail is located on each different type of sandpaper. Above, rotate the screw (a) to fix it; use the sample clamp 7 to fix the metal sample 9, and install a spring 8 with a suitable force to make the metal sample close to the surface of the sandpaper, and the screw (a) is used to fix the parallel guide rail With the case, screws (b) and (c) are used to fix the metal specimen above the specimen holder. Holding the sample slide connecting rod 4 and moving in a direction parallel to the parallel guide rails, multiple samples fixed on the sample holder 7 start to be polished at the same time.

In this example, three sandpapers are used to grind the sample, the grinding disk is divided into three concentric square disks, the sandpaper is cut to be consistent with the size of the three square disks, and the three sandpapers are cut from the inside according to the order of the models from small to large using square rings. Fix the sample on the grinding disc outside, adjust the position of the parallel guide rail, rotate the screw of the sample fixture to fix the sample, install a spring with a suitable force, so that the sample is close to the sandpaper; some samples to be ground can be placed on the Place the sample in the slot; hold the sample sliding connecting rod, and the polishing process of the sample can be started.

Wherein, the sample sliding link 4 can be connected with multiple sliding guide rails 5, and multiple samples can be polished at the same time as required.

Wherein, the parallel guide rail 3 is fixed on the casing by screws, and the position of the parallel guide rail can be changed on the casing.

Wherein, the spring 8 can automatically load the force during the polishing process of the sample, which will not cause the sample to break away from the sandpaper.
