Embodiment 1

[0035] Such as figure 2 and Figure 5 As shown, a compound polishing method and device, firstly determine the initial polishing stiffness required by the polishing disc 1 according to the process parameters of the workpiece to be polished, and adjust the magnetic field of the ring electromagnet 2 through the shunt device 6 in the control box The strength makes the corresponding area of ​​the polishing disc 1 reach the initial grinding stiffness, Figure 5 Center 1-1 is the corresponding initial rigidity area on the polishing disc 1. Then set the magnetic field intensity of equal gradient reduction in other areas of the annular electromagnet 2 of the circumferential array on the base 3, so that the corresponding areas of the grinding and polishing disc 1 present different stiffnesses, Figure 5Among them, 1-2 and 1-3 are the areas with different stiffnesses on the polishing plate 1, and the stiffness of the polishing plate 1 gradually decreases from the area 1-1 to the area ...

Embodiment 2

[0037] Such as figure 2 and Figure 6 As shown, a compound polishing method and device, compared with Embodiment 1, this embodiment makes four kinds of different magnetic field regions correspondingly distributed on the polishing disk 1 by adjusting the magnetic field strength of the ring electromagnet 2, and the polishing disk 1 Corresponding to four different rigidity areas 1-4, 1-5, 1-6, 1-7 respectively, 1-4 is the initial grinding rigidity area required by the grinding and polishing disc 1 determined according to the processed parts, 1-5, 1-6, 1-7 are the rigidity areas on the grinding and polishing disc 5 corresponding to the magnetic field with equal gradient reduction, then the rigidity of the grinding and polishing disc 1 from the area 1-4 to the area 1-5 to the area 1-6 to the area 1-7 slowing shrieking. Before work, the base 4 is fixed on the CNC machine tool, the workpiece 9 is fixed on the workpiece fixture 8, and the polishing spindle 7 is installed on the CNC...

Abstract

The invention relates to a composite grinding and polishing method and device and aims to solve the problems of long polishing time, low efficiency and the like of a single magnetic field. The composite grinding and polishing method is provided and comprises the following steps that a grinding and polishing main shaft and a grinding and polishing disc are installed on a numerical control machine tool, and annular electromagnets arranged on a base in a circumferential array manner are fixed to the lower portion of the grinding and polishing disc; and magnetic fields of different areas of the grinding and polishing disc are adjusted through the annular electromagnets, so that the rigidity of the different areas of the grinding and polishing disc is different, and efficient grinding and polishing of parts are achieved. The invention further provides the composite grinding and polishing device which mainly comprises the annular electromagnets, the base, the grinding and polishing disc, thecontrol box, the grinding and polishing main shaft and the like. The annular electromagnets are distributed on the base in the circumferential array manner and arranged below the grinding and polishing disc, and the current of the annular electromagnets can be independently controlled. According to the composite grinding and polishing method and device, the rigidity of the corresponding areas onthe grinding and polishing disc can be adjusted by adjusting the magnetic fields of the annular electromagnets in different areas, grinding and polishing integrated machining of a workpiece is achieved, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lapping and polishing devices, in particular to a composite lapping and polishing method and device. Background technique [0002] At present, my country has carried out deep research on magnetorheological polishing technology. Magnetorheological polishing technology has the advantages of high processing precision, stable material removal rate, strong surface modification ability, and small subsurface damage. However, as the abrasive for magnetorheological polishing, magnetorheological fluid requires additional devices and the process is cumbersome. In addition, the magnetic field applying device is single and difficult to control. [0003] As a new type of intelligent material, magnetorheological elastomers not only have the technical characteristics of controllability, reversibility, and high response speed, but also have unique characteristics such as good stability compared with ordinary magnetorheol...
