A magnetic grinding and polishing method and device for the inner surface of a thick-walled ceramic tube

Abstract

The invention discloses a magnetic grinding and polishing method and device for the inner surface of a thick-walled ceramic tube. The method comprises: clamping the thick-walled ceramic tube on a three-jaw chuck; placing two permanent magnets with N-S or S-N magnetic poles respectively At both ends of the magnetic pole frame; prepare magnetic abrasives; adsorb the prepared magnetic abrasives on a V-shaped magnet, and place the V-shaped magnets adsorbed with magnetic abrasives into the thick-walled ceramic tube; magnetic abrasive particles are placed on the inner surface of the ceramic tube. Rubbing and squeezing each other to achieve polishing of the inner surface. The device includes: base, variable speed motor, cam, connecting rod, permanent magnet, magnetic pole frame, three-jaw chuck, connecting shaft, connecting shaft bearing, speed regulating motor, variable speed start switch, speed regulation start switch, mobile platform, guide rail , magnetic abrasives and V-shaped magnets. The present invention adopts linear reciprocating motion magnetic grinding process, and utilizes the flexibility of the magnetic grinding brush to perform high-precision grinding and polishing on the inner surface of the ceramic tube.

Description

technical field [0001] The invention relates to a method and device for polishing the inner surface of a ceramic tube, in particular to a magnetic grinding and polishing method and device for the inner surface of a thick-walled ceramic tube Background technique [0002] With the continuous development of industrial technology, the requirements for technology are getting higher and higher. The large thick-walled ceramic tube produced by the enterprise needs to polish the inner surface of the large thick-walled ceramic tube during the production process to improve the overall quality of the workpiece. However, since ceramics are hard and brittle materials, processing is very difficult, and its final processing accuracy and surface processing quality directly affect the performance of the workpiece. At present, manual polishing is mainly used for polishing the inner surface of ceramic tubes in China. However, manual polishing is difficult to polish the inner surface of ceramic...

Problems solved by technology

However, since ceramics are hard and brittle materials, processing is very difficult, and its final processing accuracy and surface processing quality directly affect the performance of the workpiece.

At present, the domestic polishing of the inner surface of ceramic tubes mainly adopts manual polishing process, but manual polishing method is difficult to polish the inner surface of ceramic tubes, the production efficiency is low, the surface polishing uniformity is poor, and a large number of operators are required
