Description

Technical Field

[0001] This utility model relates to the field of metallographic sample preparation and polishing technology, specifically to a metallographic sample surface polishing device. Background Technology

[0002] Polishing is a key step in metallographic sample preparation. The purpose of polishing is to remove the fine grinding marks left on the sample surface after fine grinding, and to obtain a bright mirror surface so that the metallographic structure can be observed and measured under a microscope. Current technology usually uses a metallographic sample polishing machine for polishing.

[0003] When polishing metallographic specimens, the operator needs to hold the metallographic specimen with the polishing surface facing the polishing wheel. If the operator is not careful, the metallographic specimen may slip off, causing damage to the specimen.

[0004] Therefore, we propose a metallographic sample preparation and surface polishing device. Utility Model Content

Fixing plates are vertically embedded and installed on both sides of the top of the polishing machine body. The upper part of both sides of the polishing machine body has a first moving slot for mounting the gantry frame. The gantry frame is slidably connected to the polishing machine body.

[0008] The gantry frame has a groove on one side for mounting a mounting plate. A fastener is fastened to the mounting plate on the side of the gantry frame away from the groove. The mounting plate is a vertically arranged rectangular plate structure. A sliding plate is vertically connected to the center of the side of the mounting plate near the groove. A sliding groove adapted to the sliding plate is provided in the center of the inner wall of one side of the groove.
