[0007] According to a further technical solution, drive motors are installed at the front and rear ends of the workbench, and the output end of the drive motor is connected to the tool body.

[0008] The tool body is driven by a driving motor to process the workpiece.

[0009] According to a further technical solution, an opening is provided in the middle of the second transparent baffle, and the size of the opening is larger than the diameter of the tool body.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] The utility model discloses a safety protection type milling machine which is mainly used in the scene of workpiece processing.

[0029] In this embodiment, during the workpiece processing, the workpiece is first placed on the workbench 2, and the workpiece is fixed by extending the fixing rod of the cylinder above the workbench 2. At this time, the shielding mechanism 3 is in a retracted state, and the third transparent baffle 305 is retracted inside the second transparent baffle 304, and the second transparent baffle 304 is retracted inside the first transparent baffle 303. At this time, the multi-stage telescopic cylinder 307 is driven to extend, prompting the connecting block 306 to drive the third transparent baffle 305 to move upward, and the third transparent baffle 305 slides out of the second transparent baffle 304, and then drives the second transparent baffle 304 to move upward. The workpiece is then slid out from the first transparent baffle plate 303 to achieve the unfolding effect, and the driving motor 4 is then started to drive the tool body 5 to process the workpiece. During the processing, the tool body 5 contacts the workpiece at high speed to generate flying debris. At this time, two sets of unfolded shielding mechanisms 3 are installed at the front and rear ends above the workbench 2 to block the flying debris and prevent damage to the staff operating and observing the machine nearby. After the workpiece is processed, the multi-stage telescopic cylinder 307 is driven to contract, causing the shielding mechanism 3 to contract and reset as a whole, so that the processed workpiece above the workbench 2 can be picked up.

[0030] Reference Figure 2 and Figure 3 In a preferred embodiment, an opening 6 is provided in the middle of the second transparent baffle 304, and the size of the opening 6 is larger than the diameter of the tool body 5;

[0031] Supplementary explanation: After the shielding mechanism 3 is fully unfolded, the position of the opening 6 on the second transparent baffle 304 is flush with the position of the tool body 5 , which facilitates the tool body 5 to pass through the opening 6 to process the workpiece on the workbench 2 .

[0032] Reference Figure 3 , Figure 4 and Figure 5 In a preferred embodiment, a thread groove 7 is provided at both left and right ends below the first transparent baffle 303 and at the front side of the connecting seat 301, a bolt 8 is threadedly connected inside the thread groove 7, a slide groove 10 is provided at the upper end of the connecting block 306, a sheath 11 is slidably connected inside the slide groove 10, a spring 12 is connected to the side of the sheath 11 away from the third transparent baffle 305, and a limiting groove 9 is provided above the left and right ends of the third transparent baffle 305;

[0033] In this embodiment, after the shielding mechanism 3 is used for a long time, the surfaces of the first transparent baffle 303, the second transparent baffle 304 and the third transparent baffle 305 will be worn, and the process of processing the workpiece is unclear when observed from the outside. At that time, the bolt 8 is taken out from the thread groove 7 to remove the fixation of the first transparent baffle 303 and the connecting seat 301, and then the sheath 11 is pushed to both sides to cause the sheath 11 to slide out of the limiting groove 9 on the third transparent baffle 305, and the restriction of the connecting block 306 on the third transparent baffle 305 is released. At this time, the first transparent baffle 303 and the third transparent baffle 305 can be removed with the second transparent baffle 304. After replacing the new baffle, the first transparent baffle 303 is inserted into the slot 302 of the connecting seat 301 and fixed by the bolt 8. The third transparent baffle 305 is fixed by squeezing the sheath 11 by the spring 12 to be embedded in the limiting groove 9. In this way, the baffle replacement is completed for subsequent use.

[0034] Working principle: When in use, during the workpiece processing, the workpiece is first placed on the workbench 2, and the workpiece is fixed by extending the fixing rod of the cylinder above the workbench 2. At this time, the shielding mechanism 3 is in a retracted state, and the third transparent baffle 305 is retracted inside the second transparent baffle 304, and the second transparent baffle 304 is retracted inside the first transparent baffle 303. At this time, the multi-stage telescopic cylinder 307 is driven to extend, prompting the connecting block 306 to drive the third transparent baffle 305 to move upward, and the third transparent baffle 305 slides out of the second transparent baffle 304, and then drives the second transparent baffle 303 to move upward. 04 slides out from the first transparent baffle 303, thereby achieving the expansion effect, and then the drive motor 4 is started to drive the tool body 5 to process the workpiece. During the processing, the tool body 5 contacts the workpiece at high speed to generate flying debris. At this time, two sets of expanded shielding mechanisms 3 are installed at the front and rear ends above the workbench 2 to block the flying debris and prevent damage to the staff operating and observing the machine. After the workpiece is processed, the multi-stage telescopic cylinder 307 is driven to contract, so that the shielding mechanism 3 is contracted and reset as a whole, so that the processed workpiece above the workbench 2 can be picked up.
