Automatic diamond grinding wheel trimming device

Abstract

The invention discloses an automatic diamond grinding wheel trimming device which is mainly composed of a working table, a chuck and a cylinder body. The chuck is fixed below an upper top plate of the working table and comprises a small bevel gear (11) and a big bevel gear (12) which are meshed with each other. The big bevel gear is connected with a sliding block (15). An energy converter (9), an amplitude-change pole (13) and a diamond stylus (14) are arranged on the sliding block. The energy converter is connected with an ultrasonic generator. A ball screw penetrates through a fixed supporting plate to be connected with a servo motor. A guide shaft penetrates through a movable supporting plate to be connected with an upper cylinder body and the fixed supporting plate. A three-phase asynchronous motor is connected with a grinding wheel (23) through a main shaft. One end of a circuit board is connected with a proximity switch, and the other end of the circuit board is respectively connected with the servo motor and the three-phase asynchronous motor. By means of the automatic diamond grinding wheel trimming device, ultrasonic elliptic vibration of the diamond stylus can be achieved, machining efficiency and machining accuracy of the grinding wheel are improved, rigidity and stability of a cutting system are enhanced, the service life of the diamond stylus can be prolonged, and the automatic diamond grinding wheel trimming device is relatively suitable for trimming grinding wheels made of hard materials.

Description

technical field [0001] The invention relates to a multi-point ultrasonic elliptical vibration automatic dressing device for a diamond grinding wheel, which belongs to the technical field of mechanical processing. Background technique [0002] At present, the commonly used grinding wheel dressing methods at home and abroad generally have the disadvantages of low dressing efficiency, low dressing precision and high dressing cost for high-hardness difficult-to-machine grinding wheels. In addition, for this type of grinding wheel, the commonly used efficient dressing methods also have their own characteristics. Although the ELID on-line electrolytic dressing method can make it in the real-time control dressing stage, so that the grinding wheel can obtain higher dressing accuracy, but the processing equipment is too large and the processing cost is high. The dressing of the cup-shaped grinding wheel mainly depends on the abrasives that fall off from the cup-shaped grinding wheel...

AI Technical Summary

Problems solved by technology

Single-point ultrasonic grinding wheel dressing is to apply ultrasonic vibration to a single diamond pen or grinding wheel. This type of dressing device has a simple structure and is easy to operate. However, during the dressing process, the diamond pen needs to withstand large cutting force and cutting heat. time limit

In addition, due to the weak rigidity of the output shaft of the motor in the single-point ultrasonic grinding wheel dressing device, it is difficult to meet the design requirements for the final dressing accuracy of the grinding wheel
