Material-collecting fixture for thermal simulation compression sample during linear cutting and bisecting

Abstract

The invention relates to a material-collecting fixture for a thermal simulation compression sample during linear cutting and bisecting. The material-collecting fixture comprises a hollow rectangular frame body (1a) and a pressure bar component (2) arranged in the rectangular frame body, wherein a longitudinal centering notch (1e) is formed at one end of the rectangular frame body; a through hole (1f) with internal threads is formed in the center of the other end of the rectangular frame body; the pressure bar component comprises a transmission screw rod (2g); one end of the transmission screwrod passes through the through hole (1f) and is in threaded connection with the rectangular frame body; a stepped penetrating cover (2h) is fixedly sleeved at the other end, near the end head (2k), of the transmission screw rod; a cylindrical sleeve (2a) is sleeved on the penetrating cover; one end, near the stepped penetrating cover, of the cylindrical sleeve is opened; an end cover (2a1) is arranged at the other end of the cylindrical sleeve; and a compression spring (2b) is arranged between the end head (2k) and the cylindrical sleeve. The original external cylindrical surface clamping is changed into end face laminated clamping and the end faces are matched with each other well, so the clamping stability is improved and batch processing is realized.

Description

technical field

[0001] The invention relates to a collection fixture for wire cutting and bisection of a sample, in particular to a collection fixture for wire cutting and bisection of a thermally simulated cylindrical compressed sample. Background technique

[0002] In the field of material analysis, using molybdenum wire to cut a cylindrical metal sample compressed by a thermal simulation compressor (hereinafter referred to as a thermal simulation compression sample) in half is the best way to cut the thermal simulation compression sample ( Figure 12 ) The mechanical processing procedure set by the metallographic analysis of the fault structure. The shape of the sample is relatively small, with a diameter of 1.5cm and a length of 1.5cm. The cutting precision is relatively high, and the processing error is required to be within 0.2mm.

[0003] Existing wire-cutting jigs can only use the method of clamping the cylindrical surface to perform wire-cutting on the above-mention...
