Specifically, the first drive mechanism includes a rotating shaft 13 fixedly connected to both sides of the pneumatic chuck, a first motor 14 mounted on one side of the frame, a first transmission shaft connected to the first motor via a coupling, a first main gear 15 connected to the first transmission shaft, and a first sub-gear 16 connected to one of the rotating shafts. The two rotating shafts 13 are rotatably connected to the frame 6 and the two support platforms 2, respectively, and the first main gear 15 is meshed with the first sub-gear 16. After the pneumatic chuck 3 clamps the valve plate, the first motor 14 is started to drive the first transmission shaft to rotate, and through the cooperation of the first main gear 15 and the first sub-gear 16, the rotating shaft 13 is driven to rotate, thereby driving the pneumatic chuck 3 to rotate, so as to dump the debris generated during drilling into the waste bin 4.

[0031] The base 1 is connected to a frame 6, and the frame 6 is connected to a box 7 via a lifting mechanism. The lifting mechanism includes a second cylinder 17 mounted on the frame and a first guide rod 18 slidably connected to the frame. The telescopic end of the second cylinder 17 and the lower end of the first guide rod 18 are both connected to the box 7. The second cylinder 17 is controlled to operate to drive the box 7 to rise and fall. The provision of the first guide rod 18 can improve the stability of the lifting of the box 7.

[0032] A rotating column 8 is rotatably connected to one side of the housing 7. A second driving mechanism for driving the rotating column 8 is provided within the housing 7. The second driving mechanism includes a second motor 19 installed within the housing, a second transmission shaft connected to the second motor via a coupling, a second main gear 20 connected to the second transmission shaft, and a second sub-gear 21 connected to the rotating column. The second main gear 20 meshes with the second sub-gear 21. The lower end of the rotating column 8 is connected to a U-shaped mounting bracket 9. When the second motor 19 is started, the second transmission shaft is driven to rotate. The cooperation of the second main gear 20 and the second sub-gear 21 drives the rotating column 8 to rotate, thereby driving the mounting bracket 9 to rotate.

[0033] A first air cylinder 10 is provided on the inner side of one end of the mounting frame 9. A first drill 11 is connected to the telescopic end of the first cylinder 10. The central axis of the first drill 11 coincides with the central axis of the rotating column 8, and the extension of the central axis of the first drill 11 is located at the center of the pneumatic chuck 3.

[0035] The working principle of this embodiment is:

[0036] The valve plate 30 is fixed by the pneumatic chuck 3, and then the position of the second drill rig 12 is adjusted according to the groove position of the sealing groove, and then the second cylinder 17 is controlled to extend to drive the box body 7 to descend, and then the first cylinder 10 is controlled to extend to drive the first drill rig 11 to descend, so that the first drill rig 11 contacts the valve plate, and the center hole 31 is drilled in the center of the valve plate 30 by the first drill rig 11. When the center hole 31 is drilled, the first cylinder 10 contracts to separate the first drill rig 11 from the valve plate 30, and then the second cylinder 17 is controlled to continue to descend to make the second drill rig 12 contact the valve plate 30, and then the second motor 19 is started to drive the rotating column 8 to rotate. When the rotating column 8 rotates, it drives the mounting frame 9 to rotate, so that the second drill rig 12 rotates with the first drill rig 11 as the center, and a sealing groove 32 is opened on the valve plate by the second drill rig 12. Both can be carried out simultaneously, which greatly improves the processing efficiency of the valve plate. After the processing is completed, the first motor 14 is started to drive the rotating shaft 13 to rotate, thereby driving the pneumatic chuck 3 to rotate, so as to dump the debris on the valve plate into the waste bin 4 and discharge it through the discharge pipe 5 to prevent the debris from being scattered everywhere.

[0037] Example 2

[0038] This embodiment differs from Embodiment 1 in that mounting cavities are provided on both sides of the waste bin on the frame 6, within which a third cylinder 28 is mounted. A support plate 29 is connected to the telescopic end of the third cylinder 28, which is located below the pneumatic chuck 3. After the pneumatic chuck 3 secures the valve plate, the third cylinder 28 is controlled to extend, driving the support plate 29 upward. The support plate 29 supports the pneumatic chuck 3, maintaining stability during machining and facilitating valve plate machining. After machining is completed, the third cylinder 28 is controlled to retract, causing the support plate 29 to move away from the pneumatic chuck 3, facilitating flipping of the pneumatic chuck 3 and tilting away debris.
