Description

Technical Field

[0001] The utility model relates to the technical field of CNC machine tool processing equipment, in particular to a CNC machine tool spindle cleaning and blowing structure. Background Art

[0002] At present, when CNC machine tools are processing products, the chips generated are generally discharged into the chip conveyor as the workpiece rotates and the cutting fluid is flushed, and then transported to the chip removal trolley through the chip conveyor; usually, the chips on the workpiece surface cannot be completely discharged, and some chips will remain on the workpiece surface. The chips remaining on the workpiece surface are difficult to clean automatically.

[0003] There are two main existing solutions to the above problems: First, after the workpiece is processed, the operator uses an air gun or water gun to manually blow or flush away the chips remaining on the workpiece surface; when the processing time of a workpiece is long and the amount of chips is large, more chips will remain on the workpiece surface, which requires pausing in the middle of the processing and cleaning the chips on the workpiece surface. In addition, the time of opening and closing the CNC machine tool door will seriously affect the processing efficiency and increase the extra workload for the operator; Second, a cleaning and blowing structure is directly added to the outside of the spindle shield, but the cleaning and blowing structure lacks effective protection in the processing environment and occupies the machine tool space. In the processing scenario, it will shorten the spindle's movement stroke. In severe cases, the cleaning and blowing structure may also interfere with the workpiece.

[0004] Therefore, designing a CNC machine tool spindle cleaning structure that can achieve effective protection, save internal space of the machine tool, will not interfere with the workpiece, shorten processing time, and improve processing efficiency is a problem that needs to be solved urgently at this stage.
