Automatic Dressing Device for Diamond Grinding Wheel

Abstract

The invention discloses an automatic dressing device for a diamond grinding wheel, which is mainly composed of a workbench, a chuck, and a cylinder body. The chuck is fixed under the upper top plate of the workbench. The gear (12), the large bevel gear is connected with the slider (15), the transducer (9), the horn (13) and the diamond pen (14) are installed on the slider, and the transducer is connected with the ultrasonic generator , the ball screw is connected to the servo motor through the static support plate, the guide shaft is connected to the upper cylinder and the static support plate through the dynamic support plate, the three-phase asynchronous motor is connected to the grinding wheel (23) through the main shaft, and one end of the circuit board is connected to the The proximity switch is connected, and the other end is connected with the servo motor and the three-phase asynchronous motor respectively. The invention can realize the ultrasonic elliptical vibration of the diamond pen, improve the processing efficiency and precision of the grinding wheel, enhance the rigidity and stability of the cutting system, prolong the service life of the diamond pen, and is more suitable for dressing of the hard grinding wheel.

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
