External cylindrical superfinishing machine

Abstract

The invention provides an external cylindrical superfinishing machine. The machine comprises a frame, a workbench and an abrasive belt, wherein a transverse guide rail, a transverse sliding table, a transverse motion driving mechanism, a longitudinal guide rail, a longitudinal sliding table and a longitudinal motion driving mechanism; a headstock, a headstock center and a rotary driving mechanism are arranged on one side of the transverse sliding table; a tailstock, a sleeve, a tailstock center and a center adjustment mechanism are arranged on the other side of the transverse sliding table; an abrasive belt rack, an abrasive belt driving shaft, an abrasive belt driven shaft, an abrasive belt motor, a rolling abrasive belt wheel, a releasing abrasive belt wheel, a polishing wheel, a polishing wheel rack and a polishing motor are arranged on the transverse sliding table; one end of the abrasive belt winds the releasing belt wheel, and the other end of the abrasive belt moves around the polishing wheel and is fixedly arranged on the releasing abrasive belt wheel. The external cylindrical superfinishing machine has the beneficial effects of simple and compact structure, convenience in operation, integral operation stability and reliability and high processing accuracy, and cannot cause scrap of axial parts.

Description

technical field [0001] The invention relates to an outer circle superfinishing machine. Background technique [0002] In the prior art, high-precision cylindrical grinders are generally used for high-precision machining of the outer circular surface of shaft parts, and high-precision cylindrical grinders generally use grinding wheels for processing, because the hardness of the grinding wheel is relatively large, and the grinding wheel There are impurities inside, which not only affect the machining accuracy, but also damage the shaft parts in serious cases, causing the shaft parts to be scrapped. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a superfinishing machine for outer circles that has a simple and compact structure, is convenient to use, has high machining accuracy, and does not cause shaft parts to be scrapped. [0004] The technical solution of the present invention to so...
