[0031] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Embodiment 1

[0032] As Figures 1-3 shown, a vertical milling machine with a protective function includes a base 1.

[0033] A protective cover 3 is fixed to the top of the base 1 by bolts. A placement frame 2 is provided on one side of the protective cover 3. A sealing plate 12 is in transmission cooperation with the outside of the protective cover 3 through a driving component. The driving component includes a second motor 10, a guide rod 15 and a lead screw 16. Sliders 13 are fixedly connected to both sides of the sealing plate 12. One of the sliders 13 is slidably connected to the outer wall of the guide rod 15, and the other slider 13 is threadedly connected to the outer wall of the lead screw 16. The guide rod 15 is fixedly connected to the opposite sides of the base 1 and the protective cover 3. The lead screw 16 is rotatably connected to the opposite sides of the base 1 and the protective cover 3. The second motor 10 is fixed to the top of the protective cover 3 by bolts, and the output shaft of the second motor 10 is fixedly connected to one end of the lead screw 16 through a coupling.

[0034] Start the second motor 10 to drive the lead screw 16 to rotate, so as to drive the sealing plate 12 to lift and lower by means of the slider 13. When the sealing plate 12 is located at the placement frame 2, the placement frame 2 is blocked, so that the protective cover 3 forms a closed space to prevent waste chips from splashing. When the sealing plate 12 leaves the placement frame 2, the workpiece to be processed can be placed into the protective cover 3 through the placement frame 2 for milling processing.

[0035] By providing the protective cover 3 and the sealing plate 12 in this device, and using the sealing plate 12 to block the placement frame 2, the protective cover 3 forms a closed space, realizing all-round protection and avoiding damage to workers caused by the splashing of waste chips.

[0036] Referring to Figure 3 and Figure 4 , pleated telescopic tubes 11 are fixedly connected to both the top and bottom of the slider 13, and the pleated telescopic tubes 11 are located outside the lead screw 16.

[0037] The other end of one of the pleated telescopic tubes 11 is fixedly connected to the lower surface of the top of the protective cover 3 , and the other end of the other pleated telescopic tube 11 is fixedly connected to the top of the base 1 .

[0038] A screw rod 16 is provided at one end of the two pleated telescopic tubes 11 close to the slider 13 .

[0039] The pleated telescopic tube 11 is used to shield the screw rod 16 to prevent dust from falling onto the surface of the screw rod 16. When the slider 13 rises and falls, the two pleated telescopic tubes 11 are squeezed and stretched alternately. When the pleated telescopic tube 11 is squeezed, the internal air is discharged through the air holes 17. When the pleated telescopic tube 11 is stretched, the volume of its inner cavity increases, thereby generating negative pressure, and sucking in the outside air again, thereby forming a fixed air circulation to assist heat dissipation.

[0040] The device is provided with a pleated telescopic tube 11, which can shield the screw rod 16 to prevent dust from falling on the surface of the screw rod 16. The pleated telescopic tube 11 can also replace the internal air during the telescopic process to form a fixed air circulation, thereby discharging the heat generated by the friction between the screw rod 16 and the slider 13.

[0041] In this embodiment, the base 1 is fixedly connected to the top of the inner side of the protective cover 3 with a hydraulic rod 4 and a fuselage 7, the top of the fuselage 7 is fixedly connected to a motor 9, and the output end of the motor 9 is fixedly connected to a milling tool 8 through a coupling.

[0042] The telescopic end of the hydraulic rod 4 is fixedly connected with a lifting plate 6, and the lifting plate 6 is slidably matched with the side wall of the fuselage 7, and the top of the lifting plate 6 is matched with a sliding plate 5 through a set of linear displacement mechanisms, and the top of the sliding plate 5 is matched with a bearing plate 21 through another set of linear displacement mechanisms. The two sets of linear displacement mechanisms have the same structure and are arranged perpendicular to each other. In this embodiment, the specific structure of the linear displacement mechanism is not limited, and it can be an electric slide rail-slider, a screw-slider, etc. The above are all prior arts and are well known to those skilled in the art, so they are not described in detail.

[0043] Place the workpiece to be processed on the top of the carrying plate 21, start the hydraulic rod 4 to drive the lifting plate 6 to move up and down to change the height of the workpiece, and use two sets of linear displacement mechanisms to change the front, back, left and right positions of the workpiece. After the position adjustment is completed, start the motor 9 to drive the milling tool 8 to perform milling operations on the workpiece.

[0044] In this embodiment: When machining a workpiece, start the second motor 10 to drive the sealing plate 12 to rise, then place the workpiece on the top of the bearing plate 21, use the hydraulic rod 4 and two sets of linear displacement mechanisms to change the position of the bearing plate 21 and the workpiece. After the position adjustment is completed, start the second motor 10 to drive the sealing plate 12 to descend to seal the placement frame 2 to prevent waste chips from splashing. Subsequently, start the first motor 9 to drive the milling cutter 8 to machine the workpiece. Embodiment 2

[0045] A vertical milling machine with a protection function. In this embodiment, the following improvements are made on the basis of Embodiment 1, as Figures 1-6 shown:

[0046] A limiting plate 14 is fixedly connected to the side wall of the protective cover 3. An electrode A 19 and an electrode B 20 are fixedly connected inside the limiting plate 14. A conductive sheet 18 cooperating with the electrode A 19 and the electrode B 20 is fixedly connected to the bottom of one of the sliders 13.

[0047] The electrode A 19 and the electrode B 20 are connected in series in the power supply circuit of the first motor 9.

[0048] In this embodiment: When the slider 13 descends to seal the placement frame 2, the conductive sheet 18 contacts the electrode A 19 and the electrode B 20, enabling the first motor 9 to be powered on.

[0049] By setting the conductive sheet 18, the electrode A 19 and the electrode B 20 in this device, after the conductive sheet 18 follows the slider 13 to descend and contacts the electrode A 19 and the electrode B 20, the first motor 9 is powered on. And at this time, the slider 13 has sealed the placement frame 2, ensuring that the first motor 9 can be started to drive the milling cutter 8 for cutting operations only when the protective cover 3 is in a closed state, increasing the operation safety.

[0050] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
