Description

Technical Field

[0001] The invention belongs to the technical field of alumina ceramic processing, and in particular relates to a ceramic tube shell automatic turning detection system and a working method thereof. Background Art

[0002] The vacuum interrupter is the core component of medium and high voltage power switches. It is widely used in power, switchgear, high voltage power transmission and transformation industries due to its excellent electrical, thermal and mechanical properties. The alumina ceramic shell is one of the key parts of the vacuum interrupter. The current production process of the alumina shell consists of powder preparation, pressing, turning and high temperature sintering. The turning process of the blank is particularly important for the dimensional accuracy and quality of the ceramic shell after sintering.

[0003] Generally speaking, in the existing turning process of ceramic tube shells, manual work is responsible for loading and unloading ceramic blanks on lathe fixtures. Manual measurement of blank processing dimensions and manual adjustment of turning program parameters are performed to start batch CNC turning processing. After turning is completed, manual repair of blank surfaces is performed one by one and centralized transportation is carried out to the blowing platform. Manual holding of blanks is performed with high-pressure air guns to blow away the dust on the surface of parts, and then they are placed on the transfer vehicle after meeting the requirements.

[0004] The traditional turning process of alumina ceramic shells mainly relies on manual work such as product size measurement and adjustment, workpiece reciprocating handling, lathe loading and unloading, blank clamping, and surface dust blowing and cleaning. The labor intensity is high, the dependence is strong, and the processing equipment has low mechanical and automation levels, and the operation quality is unstable during continuous production.

[0005] For example, in the prior art, a fully automatic alumina ceramic vacuum tube shell forming production device and method provided by the Chinese invention patent with publication number CN117719048A includes a material conveying mechanism, a forming mechanism, a transmission mechanism, a stamping mechanism, a gripping mechanism, a turning mechanism, and a placement platform. The material conveying mechanism conveys the powder to the forming mechanism, and the forming mechanism enters the stamping mechanism through the transmission mechanism for stamping and forming, and then is transported to the turning mechanism through the gripping mechanism for surface processing, and finally placed on the placement platform. However, due to the characteristics of alumina ceramic materials - low strength of the blank and dust from turning powder, the blank is prone to cracking, reciprocating handling and collision during the lathe turning process of the existing device. At the same time, the manual measurement of the size is unstable, and the processing size fluctuates, which greatly affects the product processing quality of the alumina ceramic tube shell. At the same time, the lathe turning process and the surface soot blowing process cannot be closed for processing, the workshop site is full of dust, and the control is difficult. The site environment is dirty and messy, and the dust in the process site environment is easy to have an adverse effect on the health of the staff. Summary of the invention
