Description

A grinding wheel corrector

technical field

The invention relates to a grinding wheel corrector, in particular to a grinding wheel corrector with simple structure, convenient operation and use, and high correcting precision.

Background technique

Grinding wheel machine is a commonly used machining equipment, usually used for grinding various tools or plates, etc., which often leads to a large loss of grinding wheel, and the phenomenon of uneven thickness and width of the grinding wheel directly leads to the failure of the tool For normal maintenance, low precision of grinding parts, etc., it is necessary to use a diamond correction knife to regularly dress the grinding wheel. Generally, a hand-held diamond correction knife is used to correct the rotating grinding wheel, but due to the small holding force, the diamond correction knife often follows the grinding wheel. The correction surface changes, so the grinding wheel correction is not only low in efficiency, poor in accuracy, but also time-consuming and laborious in correction operations.

A Chinese patent discloses a grinding wheel corrector for a cork cylindrical grinder (CN201389800Y), which consists of a base frame fixed on the bed and a corrector body. The grinding wheel tool holder is installed on the corrector body, and the corrector body slides with a linear guide rail. Connection, the corrector body is connected with the transmission system. The transmission system is composed of a double nut mechanism, a motor, a reducer and a transmission screw. The double nut mechanism is fixed on the corrector body and screwed with the transmission screw. One end of the transmission screw is connected to the The output terminal of the reducer of the motor is connected. This device clamps the correcting tool by setting the tool holder on the corrector, and the tool holder is linearly guided by the transmission screw to improve the correction accuracy of the grinding wheel, but the structure of the device is complicated, and the correcting tool in this device does not have a positioning device. The positioning is only based on the transmission screw, and the thread backlash on the transmission screw will cause the correction tool to shake, the positioning accuracy of the correction tool is low, and the correction accuracy is poor. At the same time, the correction tool cannot be fed radially along the grinding wheel, so outside the correction wheel It is necessary to change the relative position of the bracket and the grinding wheel several times for the edge surface and both sides, and the change of the machining reference will reduce the correction accuracy and correction efficiency of the grinding wheel.
