Abstract

The invention provides a metallographic specimen preparation device. The metallographic specimen preparation device comprises a dividing head rotating motion mechanism, a transverse horizontal reciprocating linear motion mechanism and a vertical direction reciprocating linear motion mechanism. A dividing head of the dividing head rotating motion mechanism is in direct contact with three uniformlydistributed floating cylindrical rollers without the requirement of coaxiality, four small grooves are uniformly distributed on the excircle surface of the dividing head, spring pins are embedded in the small grooves every time the dividing head rotates for 90 degrees to realize the accurate dividing of the dividing head on 4*90 degrees. The vertical direction reciprocating linear motion mechanismdrives a ball screw nut pair by a servo motor, can accurately control the distance of a sliding plate in the vertical direction, can accurately control the grinding dosage, and ensures the effects ofgrinding and polishing. The transverse horizontal reciprocating linear motion mechanism can enable a specimen to fully cover sandpaper by adjusting the lengthening or shortening of a front transversearm, the utilization rate of the sandpaper is greatly improved, and the cost is reduced. The metallographic specimen preparation device is simple in structure, stable in operation, accurate in transmission, uniform in grinding, high in efficiency and good in flexibility.

Description

technical field [0001] The invention relates to the field of sample preparation devices, in particular to a metallographic sample preparation device. Background technique [0002] Metallographic analysis plays an important role in the field of metal material research. The properties of metal materials can be studied by analyzing the microstructure of metal materials. With the continuous improvement and development of detection equipment such as metallographic microscopes and electron microscopes, metallographic analysis has gradually advanced to a higher level. In order to meet the needs of this development, the metal material sample preparation technology and equipment should also have corresponding development. Sample preparation is an important premise and basis for microstructure testing. First, a sample that can reflect the real structure of the material to be tested must be prepared, and "pseudo-tissue" cannot be formed due to improper operation in the sample preparat...
