Cup type grinding wheel trimming device

Abstract

A cup-shaped wheel dresser relates to a non-sphere processing grinding wheel; the wheel dresser provides a cup-shaped wheel dresser; the height and inclination of the wheel dresser are adjustable and the wheel dresser has the oscillating function. The wheel dresser is equipped with a base, an oscillating arm support saddle, an oscillating arm rotary shaft, a dressing grinding wheel, a grinding wheel panel, a main shaft, a main shaft band wheel box, servo motors, transmission mechanisms, a screw, a bolt, a supporting round stick, a triangle support saddle, runners and a numerically controlled system. The oscillating arm is equipped on the base and the oscillating arm base is connected with the oscillating arm rotary shaft. The grinding wheel is connected with the main shaft and the grinding wheel is installed on the main shaft; the main shaft is connected with the main shaft band wheel box; the first servo motor is connected with the main shaft by the first transmission mechanism and the second servo motor is connected with the oscillating arm rotary shaft by the second transmission mechanism. The bottom of the main shaft band wheel box is connected with the triangle support saddle and fixed on the triangle supported saddle; the bolt is equipped under the triangle support saddle and the triangle support saddle is connected with the oscillating arm; the screw is equipped on the oscillating arm and the triangle support saddle is linked with the lower end of the screw; the triangle support saddle and the oscillating arm are equipped with runners and the numerically controlled system is connected with the servo motors.

Description

technical field [0001] The invention relates to a grinding wheel for processing aspheric surfaces, in particular to a special cup-shaped grinding wheel dresser with adjustable height and inclination angle and swing function. Background technique [0002] At present, diamond grinding wheels are usually used for grinding optical materials. The diamond grinding wheel used for grinding aspheric surfaces can be divided into four types according to the shape of the outer peripheral section: flat grinding wheel, inclined (round table) grinding wheel, arc grinding wheel and spherical grinding wheel. Grinding not only requires grinding precision, but also requires grinding efficiency. Grinding wheel is a key component of grinding. In addition to its own structure, the modification method of the machined surface is also an important factor affecting the grinding performance of the grinding wheel. The purpose of shape modification is to eliminate the shape errors and surface defects o...

Problems solved by technology

However, the modification mechanism of the cup-shaped grinding wheel mainly depends on the abrasive removal of the bond by the abrasive, which causes a large loss of the grinding wheel dresser and requires a more complicated special modification device. These factors limit its precision and Application range in ultra-precision grinding
