[0023] Embodiment 2:

[0024] like Figure 1 and Figure 2As shown, a protective dust removal mechanism 7 is installed between the outer surface of the machine head 6 and the upper surface of the third connection frame 4. The protective dust removal mechanism 7 includes a transparent protective cover 71 slidably mounted on the outer surface of the machine head 6. A vacuum cleaner 72 is fixedly mounted on the upper surface of the third connection frame 4.

The operation of the vacuum cleaner 72 can absorb the smoke and dust generated during processing, and then purify it through the air purifier 74 to avoid air pollution and improve the protective effect, thereby solving the problem that the existing machining center can only perform splash protection but cannot process smoke and dust, thereby reducing practicality.

[0025] Embodiment 3:

[0026] like Figure 1 and Figure 3 As shown, a cleaning mechanism 8 is installed on the upper surface of the workbench 1, and the cleaning mechanism 8 includes a rectangular frame 81 fixedly connected to the upper surface of the workbench 1, a screw rod 82 is rotatably connected to one side of the inner part of the rectangular frame 81, a scraper 83 is threadedly connected to the outer surface of the screw rod 82 and is slidably connected to the inner wall of the rectangular frame 81, and the lower surface of the scraper 83 is in contact with the upper surface of the workbench 1.

The operation of the vacuum cleaner 72 can suck away the smoke and dust generated during processing, and then purify it through the air purifier 74 to avoid air pollution and improve the protection effect, thereby solving the problem that the existing machining center can only provide splash protection but cannot process the smoke and dust, thereby reducing practicality. When the workbench 1 needs to be cleaned, it is only necessary to start the motor 84. The rotation of the motor 84 drives the screw rod 82 to rotate, and the scraper 83 is driven back and forth by the thread to scrape the debris that falls on the workbench 1 and drop it into the collection frame 92 through the discharge chute 91. There is no need for manual cleaning of the table surface, which reduces the workload, thereby solving the problem that the existing machining center is convenient for collecting table surface debris but still requires manual wiping and cleaning, which increases the workload.
