Semi-automatic polishing machine for laboratory

Abstract

The invention discloses a semi-automatic polishing machine for a laboratory. The semi-automatic polishing machine for the laboratory comprises a base; a workbench is fixedly installed on one side of the top of the base; two symmetrically arranged sliding grooves are formed in the top of the workbench; a clamping plate is installed in each sliding groove in a sliding manner; a through hole is formed in one side of each clamping plate; the inner walls of the two sides of each through hole are each provided with a limiting groove; a same sliding table is installed in the two limiting grooves located in the same clamping plate in a sliding manner; a stepping motor is fixedly installed on the top of each sliding table; a lead screw is welded to an output shaft of each stepping motor; a positioning plate is installed on the outer side of each lead screw in a threaded manner; the bottoms of the positioning plates are welded to the top of the workbench; and the two clamping plates are both located between the two positioning plates. The semi-automatic polishing machine for the laboratory is high in practical performance, simple in structure, convenient to operate, capable of withdrawing the arc-shaped clamping plates into the through holes as required, so that a cylindrical or rectangular polished piece can be conveniently clamped, and use is greatly convenient for people.

Description

Technical field [0001] The invention relates to the technical field of semi-automatic polishing machines, in particular to a semi-automatic polishing machine for laboratory use. Background technique [0002] There are many types of polishing machines used in the laboratory. When polishing samples, they are often hand-held and pressed against the surface of the sample to polish repeatedly. In this method, the stability of the sample is insufficient and it is prone to danger. After retrieval, the authorized announcement number Provide a semi-automatic polishing machine for the patent document of CN104889861B. This design includes base, ball screw, guide rail, screw nut, column, beam, hand wheel, crank, connecting block, polishing machine support plate, polishing machine, fixture , Worm gear lifting platform, the column is fixedly connected to the screw nut, the screw nut is connected with the ball screw used for the front and rear lateral feed movement on the base, the cross beam i...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned design still has deficiencies. The polished samples often used in the laboratory have a cylindrical or rectangular structure, but the above-mentioned design is not convenient for clamping the cylindrical polished samples, and it is not convenient to use two Different shapes of polishing samples are used to switch the fixture, which makes it inconvenient for people to clamp the polishing samples, which is not conducive to people's use. Therefore, we propose a semi-automatic polishing machine for laboratories to solve the above problems.
