End face superfinishing machine

Abstract

An end face superfinishing machine comprises a rack and a worktable. The worktable is provided with a lower center, an abrasive belt guide rail, an abrasive belt lower clamping plate, an abrasive belt longitudinal driving mechanism, a stand frame, a center guide rail, a center sliding table and a center vertical moving driving mechanism, and the abrasive belt lower clamping plate is provided with a lower U-shaped groove. An abrasive belt upper clamping plate is arranged above the abrasive belt lower clamping plate, and the abrasive belt upper clamping plate is provided with an upper U-shpaed groove. An abrasive belt is arranged between the abrasive belt upper clamping plate and the abrasive belt lower clamping plate in a penetrating mode and provided with a plurality of notches, and the abrasive belt upper clamping plate is further provided with an abrasive belt locking device. The center sliding table is provided with an upper center. A swing sleeve is rotationally installed outside the upper center and internally provided with a fixing hole, and a swing driving mechanism is further arranged outside the swing sleeve. The end face superfinishing machine has the advantages that the end face superfinishing machine is simple and compact in structure, convenient to operate and stable and reliable in overall operation; due to the fact that the abrasion belt is low in hardness and has few impurities, the polishing precision is high, and scraps of step type centrifugal type shaft parts can be avoided.

Description

technical field [0001] The invention relates to an end surface superfinishing machine. Background technique [0002] In the prior art, in the mechanical processing of stepped eccentric shaft parts, because of their eccentricity, a special top structure is required for positioning and clamping to realize the polishing and finishing of the step end face, and the polishing object used for polishing is a grinding wheel, because the grinding wheel The hardness of the grinding wheel is relatively high, and there are impurities inside the grinding wheel. When in use, it not only affects the polishing accuracy, but also destroys the stepped eccentric shaft parts in severe cases, causing the stepped eccentric shaft parts to be scrapped and unusable. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings in the prior art, the present invention provides an end face superfinishing machine with simple and compact structure, convenient use, high polishi...

Problems solved by technology

[0002] In the prior art, in the mechanical processing of stepped eccentric shaft parts, because of their eccentricity, a special top structure is required for positioning and clamping to realize the polishing and finishing of the step end face, and the polishing object used for polishing is a grinding wheel, because the grinding wheel The hardness is relatively high, and the inside of the grinding wheel contains impurities. When in use, it not only affects the polishing accuracy, but also destroys the stepped eccentric shaft parts in severe cases, causing the stepped eccentric shaft parts to be scrapped and cannot be used.
