Auxiliary equipment for surface treatment of samples

Abstract

The invention relates to auxiliary equipment for surface treatment of samples. The auxiliary equipment comprises an index sleeve, a screw, a nut, a chuck and a support. The first end of the screw is fixedly connected with the index sleeve, the second end of the screw is fixedly connected with the tail of the chuck, and the head of the chuck is used for clamping and fixing the to-be-treated sample.The nut is in threaded connection with the screw, and the first end of the nut is sleeved with the index sleeve. The knife rest is of a cavity body structure with openings formed in the two ends, theouter wall of the second end of the nut is fixedly connected with the knife rest, and the chuck and part of the screw are arranged in a cavity body of the knife rest and can move relative to the cavity body. Scale marks for indicating the movement distance of the screw relative to the cavity body are arranged on the index sleeve and the nut. The equipment is simple in structure, low in cost and easy and convenient to operate, mechanical grinding and polishing of the metallographic samples with small sizes and high precision can be achieved, and the abrasion amount is controllable.

Description

technical field [0001] The invention belongs to the technical field of metallographic sample polishing experiments, and in particular relates to a sample surface treatment auxiliary equipment. Background technique [0002] In the physical and chemical laboratory, it is often necessary to observe the microstructure of the specimen sample, so it is also necessary to perform surface treatment such as grinding and polishing of the sample in order to observe its microstructure. [0003] In today's major universities and laboratories, the preparation of metallographic samples is mainly based on traditional manual grinding, that is, the experimenter holds the sample and directly presses it on the sample grinding and polishing equipment for surface treatment of the sample. However, the precision of the traditional method is low, and the operation requirements for the operator are high, and the process is cumbersome, time-consuming and labor-intensive. Moreover, there are many uncer...
