When the electric push rod 28 extends, the blanking plate can slide from one side of the through hole 4 to the other side of the through hole 4. During this process, the pump cover 30 discharged from the through hole 4 is dialed onto the operation platform 3.

[0033] The above-mentioned drilling device includes a base 20 provided on an operation platform 3. The base 20 is located on the side of the through hole 4. A vertical arm 21 is connected to the base 20, and a swing arm 22 is connected to the vertical arm 21. The swing arm 22 can be lifted and lowered along the length direction of the vertical arm 21. A spindle box 23 is provided on the horizontal guide rail of the swing arm 22. The spindle box 23 can move along the length direction of the guide rail. A drill bit 24 is installed on the spindle of the spindle box 23. When the swing arm 22 is lifted and lowered along the length direction of the vertical arm 21, the distance between the lower end of the drill bit 24 and the pump cover can be controlled.

A baffle 26 is connected to the free end of the telescopic rod 25. The telescopic rod 25 can lock its length after being stretched to the required length. The length of the telescopic rod 25 can be adjusted according to the thickness of the cover plate to be drilled. When the baffle 26 contacts the upper surface of the operation platform 3, the drill bit 24 just drills through the topmost cover plate.

[0035] Refer to Figure 5 As shown in the figure, when implementing the pump cover drilling and processing device in this embodiment, first open the side door and assemble a suitable bottom lining plate 9 according to the size of the pump cover 30 to be processed. Then adjust the first connecting component and the second connecting component to make the bottom area of the placement area 13 of the pump cover 30 equal to the bottom area of the pump cover 30 to be drilled. Then close the side door and move the drilling device downward. When the baffle of the limiting component contacts the operation platform 3, the drilling device completes the drilling of the topmost pump cover 30. Then move the drilling device in the opposite direction until the drill bit 24 moves above the material feeding device. Then start the electric push rod 28 and the hydraulic cylinder 6. When the hydraulic cylinder 6 lifts the pump cover 30 that has completed drilling to the through hole 4 and removes it, at the same time, the upper surface of the next pump cover 30 to be processed is flush with the upper surface of the operation platform 3. The material feeding plate 29 can move to dial the pump cover 30 that has completed drilling onto the operation platform 3. Then move the drilling device downward again and repeat the above operations.

[0036] Refer to Figure 6As shown, as another embodiment of the present utility model, the above-mentioned limit assembly is removed, and a mold 31 is placed between two adjacent pump covers. The mold 31 is provided with a through hole, and the position of the through hole on the mold 31 corresponds to the position of the hole to be drilled on the pump cover. When implementing the device in this embodiment, when the drilling device finishes drilling the uppermost pump cover 30, due to the arrangement of the through hole on the mold 31, the drill bit 24 idles, and the operator can judge whether the drilling of the pump cover 30 has been completed. Then, the hydraulic cylinder 6 lifts the pump cover 30 that has completed drilling together with the mold 31 below this pump cover out through the through port 4. The upper surface of the next pump cover 30 to be drilled is just flush with the upper surface of the operation platform. The material shifting plate 29 shifts the pump cover 30 that has completed drilling together with the mold 31 below this pump cover onto the operation platform 3. Then, the drilling device is moved downward again, and the above operation is repeated.
