Automatic abrasive disc switch device of metallographic grinder

Abstract

The invention discloses an automatic abrasive disc switch device of a metallographic grinder. The device comprises an automatic disc replacing system, a grinder main control table, a disc library mechanism and a rack, wherein the automatic disc replacing system, the grinder main control table and the disc library mechanism are fixed on the rack respectively; the grinder main control table controls automatic operation of the whole device; when an abrasive paper disc or a polishing disc of the grinder needs to be replaced, corresponding signals are transferred to step motors, and the step motors respond to corresponding signals to control the left-right movement and rotation of a control mechanism, control the up-down movement and rotation of a clamping mechanism and control the clamping and placing of a clamp holder so as to realize automatic replacement of the abrasive paper disc and the polishing disc of the grinder; and according to the automatic abrasive disc switch device, an idle center belt of disc abrasive paper of a disc grinder is fully used, the structure is simple and easy to operate, the abrasive disc can be accurately clamped, the working time of experimenters can be shortened, and the working strength of experimenters is alleviated, and the operation efficiency of the metallographic grinder is effectively improved.

Description

technical field [0001] The invention relates to an automatic device for a grinding machine, in particular to an automatic switching device for sand discs of a metallographic grinding machine. Background technique [0002] The metallographic grinder is an important equipment in the preparation process of metallographic samples. The preparation process of metallographic samples includes sample sampling, inlaying, polishing, coarse grinding, fine grinding, polishing, corrosion, etc., among which the fine grinding of samples The important equipment used for rough grinding and polishing is the metallographic grinder, and polishing is the most time-consuming and labor-intensive step in the entire metallographic sample preparation process. Due to the needs of metallographic research, various types of metallographic There are more and more grinding machine products, and with the advancement of technology, the degree of automation is getting higher and higher. In terms of grinding ma...
