Portable metallographic phase automatic sample grinding device

Abstract

The invention relates to a portable metallographic phase automatic sample grinding device. The device comprises a base body, a supporting unit, a sample grinding unit, a pressing unit, a cleaning unit and a control unit; the top of the base body is provided with a sunken machining face; a power transmission unit is installed between two opposite installation edges of the base body; the supporting unit comprises a guide rail frame and supporting frames, and the guide rail frame is erected over the power transmission unit through the supporting frames at the two ends; the sample grinding unit comprises a transmission shaft driving motor protection box, a transmission shaft driving motor, a main transmission shaft, an auxiliary transmission shaft and a plurality of groups of sample grinding conveyor belt assemblies arranged between the main transmission shaft and the auxiliary transmission shaft side by side; the pressing unit comprises a horizontal position adjusting device, a height adjusting device and a sample pressing block; the cleaning unit comprises a water spraying pipe base, a water spraying pipe and a water outflow switch; and the control unit comprises a controller, at least one first control switch and at least one second control switch. The portable metallographic phase automatic sample grinding device, automatic grinding and station changing work of a metallographic specimen are achieved by multiple pieces of belt type abrasive paper and the height adjusting device. The automatic grinding device is simple in structure, rapid, efficient and low in cost.

Description

technical field [0001] The invention relates to laboratory equipment for materials subject, in particular to a portable metallographic automatic sample grinding device, which belongs to the technical field of laboratory sample processing equipment. Background technique [0002] Metallographic structure observation is a work that is often involved in scientific research in materials science. Among them, metallographic sample preparation is an indispensable step, which is related to the success or failure of metallographic structure observation. There are two main methods of grinding samples at present, one is to grind samples with manual sandpaper, and the other is to use a sample grinder to grind samples by metallography, but both methods have shortcomings. The grinding efficiency of the sample grinding method using manual sandpaper is low, the grinding effect is not good, and the work intensity is high.

AI Technical Summary

Problems solved by technology

There are two main ways of grinding samples at present, one is manual sandpaper grinding, and the other is metallographic grinding using a grinding machine, but both methods have deficiencies

The grinding efficiency of the manual sandpaper grinding method is low, the grinding effect is not good, and the work intensity is high

Using the existing sample grinding machine for metallographic grinding can improve work efficiency, but it needs to be manually held, which greatly reduces the safety, and the metallographic grinding may be skewed due to uneven force during operation. Sandpaper needs to be replaced after several grindings, which greatly delays the time

In order to solve the above problems, there is now a sample grinding machine that does not need to be hand-held on the market. The number of meshes of the ring sandpaper increases from the inside to the outside, and there is no need to manually hold the sample when grinding the sample, which greatly improves the work efficiency and safety. However, due to Grinding samples under different meshes requires manual change of station, which is cumbersome to operate, and the pressure between the sample and the sandpaper is manually regulated by the screw, and the accuracy is not high
