Metallographic cold-inlaying device capable of adjusting inlaying position and angle of sample

Abstract

The invention discloses a metallographic cold-inlaying device capable of adjusting inlaying position and angle of a sample. The device comprises a base, wherein an inlaying sample die is arranged in the middle of the upper top surface of the base, a stand column is arranged at the edge of the upper top surface, a fixing sleeve is connected to the front end of the upper part of the stand column, a butterfly connecting nail penetrates through the fixing sleeve, and the lower end of the butterfly connecting nail is connected with a frame; the frame is formed by a connecting sleeve and at least one strut welded with the outer wall of the connecting sleeve, each strut is provided with a ball-twisting stretching jaw, and the lower end of the ball-twisting stretching jaw is arranged in the inlaying sample die. By utilizing the device, the inlaying position and angle of the sample can be freely adjusted, and the device is especially suitable for observing experiment occasion with small samples and irregular shapes and suitable for metallographic observation in an experiment occasion having angle requirement on the sample, thus meeting different observation requirements of detectors; multiple samples can be clamped in one time of inlaying, fixing positions and angles of different sample do not interfere each other, the detection efficiency is improved, and thus the device is more suitable for large-batch daily detection work.

Description

technical field [0001] The invention belongs to a metallographic cold mounting device, in particular to a metallographic cold mounting device with adjustable sample mounting positions and angles. Background technique [0002] In the process of preparing metallographic samples, many samples are difficult to grind and polish directly due to their small size and irregular shape, so sample mounting is required. The inlaid samples are not only convenient for grinding and polishing, but also can improve work efficiency. The commonly used methods of sample mounting include mechanical mounting method and resin mounting method. The resin mounting method can be divided into hot pressing mounting method and cold mounting method. The cold mounting method is more suitable for samples that do not allow heating, soft or low melting point metals, samples with complex shapes, porous samples, etc. [0003] When the observation surface of the sample is small or the shape of the sample is irr...

Problems solved by technology

With this design, the fixation of the sample will be strictly limited by the position of the sample hole, and the relative position and angle of the sample in the mounting mold cannot be freely changed

Invention patent 201420502419.2 discloses a "thin slice metallographic inlay sample fixture", which can only mount one thin slice sample at a time and the position of the thin slice sample cannot be adjusted
