Magnetic grinding and polishing method and device of inner surface of thick-wall ceramic pipe

Abstract

The invention discloses a magnetic grinding and polishing method and device of the inner surface of a thick-wall ceramic pipe. The method includes the steps that the thick-wall ceramic pipe is clamped to a three-claw chuck; one permanent magnet is placed at one end of a magnetic pole frame in an N-S mode, and another permanent magnet is placed at the other end of the magnetic pole frame in an S-N mode; magnetic grinding materials are prepared; the prepared magnetic materials are adsorbed to a V-type magnet, and the V-type magnet to which the magnetic materials are adsorbed is placed into the thick-wall ceramic pipe; magnetic grinding particles collide with one another and are squeezed mutually on the inner surface of a ceramic pipe body to polish the inner surface. The magnetic grinding and polishing device comprises a base, a variable-speed motor, a cam, a connecting rod, the permanent magnets, the magnetic pole frame, the three-claw chuck, a connecting shaft, a connecting shaft bearing, an adjustable-speed motor, a variable-speed stating switch, an adjustable-speed starting switch, a moving platform, a guide rail, the magnetic grinding materials and the V-type magnet. Linear reciprocating motion and magnetic abrasive finishing processing are adopted, and high-precision grinding and polishing of the inner surface of the ceramic pipe can be achieved through the flexibility of a magnetic abrasive finishing brush.

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
