Longitudinal polishing device

Abstract

The invention discloses a longitudinal polishing device which comprises a base plate, a first guide rail pair, a second guide rail pair and a protective cover, the first guide rail pair and the second guide rail pair are fixed to the base plate, a polishing assembly is arranged at the top of the first guide rail pair, a clamping assembly is arranged at the top of the second guide rail pair, an automatic tensioning assembly is arranged on a side surface of the polishing assembly, a first ball screw pair is arranged at the bottom of the polishing assembly, a second ball screw pair is arranged at the bottom of the clamping assembly, and the bottom of the protective cover is fixedly connected with the top of the base plate. According to the polishing device, through the arrangement of the first guide rail pair and the first ball screw pair, the polishing assembly can move in the linear direction so that a workpiece is longitudinally polished, the longitudinal polishing effect is good, lines are neat and parallel, and line intersection can be avoided; and through the arrangement of an upper abrasive belt disc and a lower abrasive belt disc, an abrasive belt can be replaced so that the abrasive belts used for polishing the workpieces are in the same state, and the difference of the polishing effect is avoided.

Description

technical field [0001] The invention relates to the technical field of polishing equipment for test samples of metal mechanical properties. Specifically, vertical throwing equipment. Background technique [0002] Longitudinal polishing belongs to a processing technology for test samples of metal mechanical properties. It is required to polish the sample along the force direction of the test, that is, longitudinal polishing. It is required that the polishing textures be parallel to each other and along the axial direction of the sample; the traditional The lathe is a rotary polishing, and its polishing lines are perpendicular to the direction of the force, which cannot meet the requirements of the sample. However, the quality of manual longitudinal polishing is unstable and is easily limited by the operator's technical level. The polishing lines are not parallel and appear to intersect each other. And in the polishing process, it is difficult to control the polishing force a...
