Abstract

The invention relates to a batch automatic grinding tool for a small diameter cylindrical sample. The batch automatic grinding tool comprises a base; the base is provided with at least one semi-open sample hole for holding the to-be-ground sample; the central angle of the solid part of each semi-open hole is greater than 180 degrees; and the inner diameter of the solid parts is in dynamic fit withthe outer diameter of the corresponding to-be-ground sample. The sample preparation efficiency is greatly improved, by machining the sample holes of different sizes, and the multiple types of samplescan be ground simultaneously; and the sample holes are blocked through side baffles, the operation is convenient, and the cost is low. Therefore, the problem of grinding of small cylindrical samples,especially gas-containing steel samples is solved, the working efficiency of processing personnel can be greatly improved, and the uniformity, precision and stability of the surface of workpieces areensured.

Description

technical field [0001] The invention specifically relates to a batch automatic grinding tool for small-diameter cylindrical samples, which belongs to the field of tooling and fixtures for grinding the outer circular surface of small cylindrical samples, and is mainly suitable for short and thin small gas content samples in steel. Specimen clamping fixture. Background technique [0002] The hydrogen content of gaseous elements in steel is tested independently, while oxygen and nitrogen are tested together. According to GB / T223.82-2007, GB / T20124-2006 and other relevant standards, gas element samples in steel should be taken as long strip samples of appropriate size, and the most common ones are processed into small cylindrical samples (commonly known as gas samples) ). Surface coatings, moisture, dust, and other forms of contamination must be removed prior to analysis of samples. [0003] In the prior art, gas samples are mostly cut by wire cutting, and the surface of the ...
