Embodiment Construction

[0024] The present invention will be described in more detail below with reference to the accompanying drawings.

[0025] Such as figure 1 , figure 2 As shown, a method for grinding and polishing the inner surface of a thick-walled ceramic tube comprises the following steps:

[0026] a. Clamp the thick-walled ceramic tube 7 on the three-jaw chuck 8 of the grinding and polishing device for the inner surface of the thick-walled ceramic tube, and use a concentricity measuring instrument to ensure the eccentricity with the rotating shaft;

[0027] b. Place two permanent magnets 5 with a size of 45*45*20 on both ends of the pole frame 6 with N-S or S-N magnetic poles, and the two permanent magnets 5 attract each other to form a magnetic circuit with respect to the magnetic poles. Simultaneously adjust the distance between the magnetic pole frame 6 and the thick-walled ceramic tube 7 so that the two permanent magnets 5 and the outside of the thick-walled ceramic tube 7 maintain a...

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...
