Description

In-situ automatic and fast chip removal device for CNC machining

technical field

The invention relates to an in-position automatic fast chip removal device for numerical control machining, which is used for parts that need to be paused and removed for chip blowing during the drilling and milling process.

Background technique

Nowadays, the processing of parts is getting closer and closer to automation, but for some machined parts, it cannot be fully automated, such as tapping and milling. After the first process is completed, there will often be a lot of waste. If it is not timely Cleaning up waste will cause great harm to processing: waste will remain in the hole when drilling. If the waste is not disposed of in time, the tap will easily break during tapping, which will increase the cost virtually. And the accuracy and quality of the thread will be affected to a certain extent; more waste chips will be generated during the milling process, and the waste chips that are not cleaned up in time will seriously affect the surface processing quality. Therefore, after the first process is processed, the waste must be removed. At present, there is no corresponding automatic machine for removing waste chips, and almost all of them use air guns to remove waste chips manually. The degree and method of removing waste chips for parts with different precision requirements are also different: for workpieces with low precision requirements Most of the time, the machine tool is suspended, and the waste chips are removed inside the machine tool with an air gun, but not all of them are removed; for workpieces requiring high precision or tapping workpieces, the parts must be disassembled and blown at the designated waste chip disposal site. crumbs. And all are done manually, which is not only time-consuming and laborious, but also the environment is harsh during the chip blowing process, and there is a certain degree of potential safety hazard.
