Abstract

The invention relates to an ultrasonic vibration auxiliary magnetic composite fluid polishing device. The polishing device comprises an electric spindle and a polishing head, the polishing head is composed of a piezoelectric ceramic ring, a permanent magnet and a polishing wheel, the polishing wheel is composed of a functional layer and a connecting layer, the functional layer and the connecting layer are welded and fixed, and the polishing wheel is fixedly connected with the electric spindle through the connecting layer; the permanent magnet is wrapped in an insulating coating and sintered in the piezoelectric ceramic ring, so that the magnetic composite fluid is adsorbed on the outer surface of the piezoelectric ceramic ring under the action of a magnetic field of the permanent magnet and is used for polishing an original grating, and the piezoelectric ceramic ring is fixedly connected with the polishing wheel through resin silica gel; an electric brush is arranged in the electric spindle, generated alternating current is connected with the piezoelectric ceramic ring through a circuit line channel arranged in the functional layer to form a loop, and thus ultrasonic vibration is generated. The polishing device is simple in structure, and the material removal rate and the polishing quality of the magnetic composite fluid on the surfaces of various workpieces are improved.

Description

technical field [0001] The invention relates to a polishing device, in particular to an ultrasonic vibration-assisted magnetic composite fluid polishing device for surface polishing of various materials. Background technique [0002] As one of the highly competitive cutting-edge manufacturing technologies, the ultra-precision manufacturing of grating components has always attracted the attention of various countries. As the core component of many optical instruments, it is widely used in the fields of spectral analysis, precision measurement and aerospace ships. However, during the manufacturing process of the grating element, it is easy to form micro-defects and pollution of different degrees on the surface, which reduces the processing quality of the grating element and limits the use efficiency of the grating element to a certain extent. microdefects. In this context, making full use of the technical advantages of the flow adaptability of the magnetic composite fluid on ...
