Demounted combination-type metallographic specimen high-efficient grinding and polishing clamp

Abstract

The invention discloses a demounted combination-type metallographic specimen high-efficient grinding and polishing clamp. The demounted combination-type metallographic specimen high-efficient grinding and polishing clamp is characterized in that one end of each of four connection rods (2) is inserted into a corresponding peripheral hole in a square-shaped central connection block (1), and the other ends of the four connection rods (2) are separately connected with a magnetic suction disc (7), so that the clamp of a cross-shaped integral structure is formed; holes for placing metallographic specimen clamping components are formed in each connection rod (2); during a specimen grinding and polishing process, well-clamped metallographic specimen clamping components are placed in the holes, and are fixed through screws (5) in the metallographic specimen clamping components. By using the demounted combination-type metallographic specimen high-efficient grinding and polishing clamp, metallographic specimens do not need to be grabbed by hand directly during a metallographic specimen preparation process, so that the problem that the specimen preparation quality is not stable enough when the specimens are held by hand and the like are solved.

Description

technical field [0001] The invention belongs to the field of experimental equipment, and relates to a high-efficiency grinding and polishing fixture for metallographic samples, in particular to a detachable and combined metallographic sample high-efficiency grinding and polishing fixture suitable for simultaneous grinding and polishing of multiple metallographic samples. Background technique [0002] Metallographic analysis is one of the important means of experimental research on metal materials, and the basis of metallographic analysis is to prepare metallographic samples that can meet the microstructure analysis. As we all know, the metallographic sample preparation process is a very tedious process. At present, due to the lack of special metallographic sample grinding and polishing fixtures, samples can only be hand-held and only one sample can be processed during sample preparation. Due to the instability of manual control, the grinding and polishing quality of metallo...
