Embodiment Construction

[0021] A new method for expanding the sample holder of the laboratory automatic sample grinding machine involved in the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0022] Such as figure 1 As shown, the method for expanding the rectangular hole slot fixture of the automatic sample grinding machine includes the following steps:

[0023] 1. Measure the length, width and height of the hole groove, the spacing of the fastening nuts, and the diameter of the fastening nuts for the rectangular sample fixture of the Struers automatic grinding machine. The values ​​are: 94mm, 54mm, 17mm, 40mm, 7mm.

[0024] 2. If it is a non-circular sample, select the φ45mm mounting machine aperture according to the shape of the rectangular sample fixture hole (the sample hole size of the Struers rectangular sample fixture is 94mm*54mm, which is suitable for placing a φ45mm mounting sample. The mounting machine aperture It is...

Abstract

The invention discloses a method for expanding a rectangular sample clamp of an automatic sample grinding machine for a laboratory. The method is characterized by comprising the following steps of measuring the relevant size of the rectangular sample clamp of the automatic sample grinding machine; measuring the gap size in the width direction of a hole groove after a circular sample is placed in;determining the size of a clamping block, and manufacturing the clamping block; punching a fixing hole in the clamping block; putting the manufactured clamping block and the circular sample into the hole groove together and performing fixation; and performing operation and sample preparation according to an automatic equipment flow. By the method provided by the invention, the use limitation of the rectangular clamp is expanded, the utilization rate of the clamp is improved, the requirement of preparation of samples in different shapes is met, and the money for purchasing corresponding clampsfor clamping the samples in different shapes is reduced.

Description

technical field [0001] The invention belongs to the technical field of laboratory material analysis and detection, and relates to an expansion method for a sample fixture of an automatic sample grinding machine. Background technique [0002] In response to the needs of current technological development and innovation, the manufacturing industry has higher and higher requirements for the quality of materials and products produced, and stricter requirements for the inspection of mechanical and physical properties of products leaving the factory. The metallographic inspection of high-end products is included in the performance inspection The proportion is getting higher and higher. In order to reduce human factors in the inspection, it is necessary to use an automatic sample grinding machine for sample preparation. The automatic sample grinding equipment uses standard or customized fixtures to fix the sample, and then performs mechanical sample preparation. High-end products gen...
