Large-size axial ultrasound-assisted end face grinding abrasive disk

Abstract

The invention discloses a large-size axial ultrasound-assisted end face grinding abrasive disk. The large-size axial ultrasound-assisted end face grinding abrasive disk comprises an outer cover, an inner cover, a coil cover, a base disk and multiple ultrasound vibration blocks. The base disk is in a concentric circle shape, a coil is arranged at the lower end of the base disk, and a motor spindle is installed in a center hole of the coil in a connected manner. The ultrasound vibration blocks are evenly distributed in the circumferential direction of the base disk and comprise ultrasound transducers, amplitude-change poles and abrasion blocks. A motor drives the base disk to rotate. Ultrasound signals are transmitted to the amplitude-change poles from the coil at the lower end of the base disk through an electric brush on the motor, and the amplitude-change poles drive the abrasive blocks to axially vibrate relative to the base disk. As the large-size axial ultrasound-assisted end face grinding abrasive disk can be used for ultrasound-assisted end face grinding and ultrasound-assisted lapping and polishing, batched ultrasound end face grinding, lapping and polishing on large parts can be achieved, and the machining efficiency and the machining accuracy of the parts are greatly improved.

Description

technical field [0001] The invention relates to a grinding disc device, in particular to a large-size axial ultrasonic-assisted end face grinding grinding disc. Background technique [0002] With the development of science and technology, brittle optical materials such as optical glass, artificial crystal, and ceramics have been widely used, and are often used to make precision optical components. Its superior physical, chemical and mechanical properties are being used more and more widely in aerospace, aviation, automobile, metallurgy, machining and other fields. However, due to the high brittleness and poor machinability of such materials, especially ceramic materials and some crystal materials have high hardness, processing is more difficult. Traditional grinding methods have low processing efficiency and processing accuracy, severe tool wear, and high processing costs, which limit the further application of these materials. Therefore, it is urgent to develop a processi...

Problems solved by technology

[0004] However, in the ultrasonic vibration-assisted grinding process, due to the characteristics of the ultrasonic vibration device itself, the ultrasonic vibration can only be applied to smaller workpieces or tools, and it is difficult to achieve ultrasonic vibration of large-sized grinding discs or workpieces.
