Ceramic tube inner surface polishing device and method

Abstract

The invention relates to the technical field of ceramic tube inner surface ultra-precision machining, in particular to a ceramic tube inner surface polishing device and method. The ceramic tube inner surface polishing device comprises a lathe, a magnetism gathering device, a peripheral magnetic pole, a peripheral magnetic pole support, an auxiliary magnetic pole, an L-shaped bevel gear angle rotator, a transmission shaft, an auxiliary magnetic pole support, a high-speed motor, a high-speed motor bracket and a photoelectric limit switch. The magnetism gathering device, the peripheral magnetic pole and the peripheral magnetic pole support are fixed to a sliding box a of the lathe. The high-speed motor, the transmission shaft, the L-shaped bevel gear angle rotator and the auxiliary magnetic pole are connected in sequence and are fixed to a sliding box b of the lathe. A ceramic tube generates rotational motion under the action of the lathe. The high-speed motor drives the auxiliary magnetic pole to rotate. The auxiliary magnetic pole and the peripheral magnetic pole synchronously conduct axial feeding. Magnetic grinding particles and the inner surface of the ceramic tube part move relatively, so that ultra-precision machining of the inner surface of the ceramic tube is completed. The ceramic tube inner surface polishing device is high in machining precision and can be widely applied to polishing of inner surfaces of ceramic tubes.

Description

technical field [0001] The invention relates to the technical field of ultra-precision machining of the inner surface of a ceramic pipe fitting, in particular to a polishing device and a polishing method for the inner surface of a ceramic pipe. Background technique [0002] With the rapid development of high-end high-tech industries such as aerospace, medical treatment, and petroleum, various new types of parts have emerged as the times require. The technical requirements for parts are getting higher and higher, not only to ensure the dimensional accuracy of the parts, but also to have better microscopic surface morphology, corrosion resistance and fatigue resistance. Ceramics have excellent properties such as high hardness, high corrosion resistance, stable chemical properties, and low-temperature superplasticity, and are increasingly used in scientific fields. However, due to its high hardness and brittleness, it is easy to produce cracks and defects during processing, an...

Problems solved by technology

In order to improve the efficiency of magnetic grinding, auxiliary polishing tools are usually added inside the pipe fittings to increase the magnetic induction intensity in a certain space, thereby increasing the grinding pressure of magnetic abrasive particles. The rigidity of the magnetic particle brush is improved and the trajectory of the magnetic abrasive particles is single during grinding. Deep scratches are easy to appear on the surface after processing, the surface quality is not easy to control, and the processing effect is not ideal.
