Surface polishing method and surface polishing device of thin-wall long and narrow ceramic tube

Abstract

The invention discloses a surface polishing method and a surface polishing device of a thin-wall long and narrow ceramic tube. According to the invention, automation control is adopted so as to greatly save labor power, improve efficiency and obtain high precision; a low-temperature alloy (with the melting point range of 50-80 DEG C) is adopted as a filling medium to fix and support the thin-wall ceramic tube, so that the defect that a common filling material cannot effectively be filled is overcome; and skin effect under intermediate frequency heating is combined to fast melt the low-temperature alloy to remove the filling material, so that the polished finishing product ratio through the machining is high and the polishing quality is good.

Description

technical field [0001] The invention relates to the field of ceramic tube processing, in particular to a method and device for polishing the surface of a thin-walled narrow ceramic tube. Background technique [0002] For ceramic tubes with a wall thickness of about 1 mm, due to the thinner wall thickness and brittle material, they often break due to local loads during polishing; when the tube is narrow and long or the diameter is large, the local Larger loads also tend to break the pipe. For the polishing of thin-walled and narrow ceramic tubes, manual polishing is mostly used now, which has high labor intensity and low production efficiency; secondly, it is difficult to accurately control the polishing amount during manual operation, and the polishing quality is unstable and the precision is poor; moreover, the polishing process In the process, the polishing powder is flying, the dust is easy to enter the human respiratory tract and skin, and the noise is loud, the product...

[0002] For ceramic tubes with a wall thickness of about 1 mm, due to the thinner wall thickness and brittle material, they often break due to local loads during polishing; when the tube is narrow and long or the diameter is large, the local Larger loads can easily break the pipe

For the polishing of thin-walled and narrow ceramic tubes, manual polishing is mostly used now, which has high labor intensity and low production efficiency; secondly, it is difficult to accurately control the polishing amount during manual operation, and the polishing quality is unstable and the precision is poor; moreover, the polishing process In the middle, the polishing powder is flying, the dust is easy to enter the human respiratory tract and skin, and the noise is loud, the production environment is harsh, endangering human health, and the labor cost is high

For ceramic tubes that require a smooth outer surface, only internal supports can be used to achieve complete polishing of the outer surface. If soft supports, such as sand, are used as internal supports, the support strength is poor, loading and unloading is inconvenient, and time-consuming; Support, only partial support, will inevitably cause uneven clamping force and fragile
