Positive and negative blade electrodes alternated type electrorheological buffing device

Abstract

The invention relates to a positive and negative blade electrodes alternated type electrorheological buffing device. The device comprises a motor, a coupler, a supporting rod, a rotation shaft, a positive electrode conductive cylinder, an insulation cylinder, a blade insulation sleeve, negative electrode buffing blades, positive electrode buffing blades and the like, wherein the negative electrode buffing blades and the lower end of the rotation shaft are fixed to form a negative electrode, and the contact position between the negative electrode and the positive electrode conductive cylinder is insulated by the blade insulation sleeve; the positive electrode buffing blades and the positive electrode conductive cylinder are fixed to form a positive electrode, the positive electrode and the rotation shaft are fixed through the blade insulation sleeve, and the positive electrode and the negative electrode buffing blades are alternatively distributed; an annulus brush is placed in a brush sleeve groove and closely contacted with the positive electrode conductive cylinder. After energization, electrorheological buffing liquids distributed between the positive electrode buffing blades and the negative electrode buffing blades are subjected to electrorheology effects to form a flexible buffing head, and workpieces are buffed by the flexible buffing head driven by the blades. According to the positive and negative blade electrodes alternated type electrorheological buffing device, by means of the streamline blades and alternatively distributed electric fields, high shearing speeds are achieved, and electrorheological buffing efficiency is effectively improved.

Description

technical field [0001] The invention relates to a polishing tool, in particular to an electrorheological polishing tool of positive and negative alternating blade electrodes, which belongs to the field of ultra-precision optical surface processing tools. Background technique [0002] With the development of optoelectronic communication technology, the size of optoelectronic device components is gradually reduced. There is a large demand for micro-optical aspheric lenses with lower surface roughness in the optoelectronic industry products, which promotes the research on new methods of aspheric lens processing. Traditional polishing tools are mainly polishing discs. When processing tiny ultra-precision three-dimensional workpieces or molds, due to the tiny surface size of the polished workpieces, it is difficult to manufacture tiny polishing molds and gather abrasives stably in the processing area, so traditional polishing methods cannot meet the processing requirements. In ...
