一种机床砂轮拆卸工装

Abstract

本实用新型涉及机床技术领域，尤其涉及一种机床砂轮拆卸工装，本实用新型机床砂轮拆卸工装与砂轮驱动结构联合设计为一体结构，其主要由安装板、定位凸环、轴向推送组件、周向旋转组件和砂轮构件构成，砂轮构件由砂轮基块和设有其外侧的打磨圈构成，砂轮基块开设有椭圆穿槽、圆形定位槽和椭圆卡槽，椭圆卡槽和椭圆穿槽呈90度错位；当需要拆卸时，先利用轴向推杆来推动椭圆卡块从椭圆卡槽中脱离，再利用周向旋转组带动椭圆卡块相对于砂轮构件旋转90度，即可利用吸盘机械手快速将砂轮构件拆卸取下，反之可进行砂轮构件的安装操作，整体拆装操作便捷，无需拆卸螺丝等紧固件，拆卸效率较高，利于实现自动化拆装。

Claims

1. A machine tool grinding wheel dismounting tool, characterized by, Includes mounting plate, positioning cam, axial push assembly, circumferential rotation assembly, and grinding wheel component; The grinding wheel component consists of a grinding wheel base block and a grinding ring with its outer side. An elliptical through groove is opened through the interior of the grinding wheel base block. A circular positioning groove and an elliptical retaining groove are opened on both sides of the grinding wheel base block, respectively. The elliptical retaining groove and the elliptical through groove have the same cross-sectional shape and are offset at 90 degrees. The mounting plate is equipped with a positioning protrusion ring that mates with the circular positioning groove. The mounting plate is also equipped with an axial pushing component and a circumferential rotating component. The axial pushing component has an elliptical locking block that can be axially displaced. The shape of the elliptical locking block matches the shape of the elliptical locking groove. The circumferential rotating component can drive the elliptical locking block to rotate circumferentially.
