Description

Technical Field

[0001] The invention relates to the technical field of notebook processing, in particular to an automatic processing device for precision parts of a notebook computer. Background Art

[0002] Notebook computers are also called "portable computers, handheld computers or laptops". They are characterized by a body that is more portable than desktop computers. They are small and easy to carry, usually weighing 1-3 times the weight. The current development trend is to get smaller, lighter and stronger. Since the size of notebook computers is smaller than that of desktop computers, notebook computers are relatively more precise and compact, which prompts the need to process the precision parts of notebook computers before production and processing. When processing the precision parts of notebook computers, CNC machine tools are required;

[0003] CNC machine tools are necessary machines for precision parts processing. They play an irreplaceable role in the processing of precision parts. When CNC machine tools process precision parts, they need to use different tools in sequence to process precision parts, which leads to the need to constantly change different tools for processing. However, when traditional CNC machine tools change tools, they first need to insert the working tool into the inner cavity of the tool magazine, and then adjust the tool magazine until the tool magazine moves the tool to be replaced to the tool outlet, and finally the tool can be replaced and installed. The steps of changing tools are relatively complicated, which causes CNC machine tools to waste a lot of time in the process of changing tools, thereby greatly reducing the production efficiency of precision parts. In addition, when traditional CNC machine tools spray cooling water on the tools, they usually spray it on the surface of the tools and precision parts. For example, when some precision parts need to be turned, it is difficult for cooling water to penetrate into the inner cavity of the processing hole, which causes the inner cavity of the processing hole and the outer wall of the tool to generate a lot of heat when processing the processing hole and cannot be cooled, ultimately shortening the service life of the tool, or causing deviations in the processing of precision parts, making it inconvenient to use.
