[0012] By adopting the above technical solution, the first chip collection box can collect the waste chips generated when drilling on the first processing table, and the second chip collection box can collect the debris generated when drilling on the second processing table, which facilitates the subsequent manual cleaning of the debris.
[0013] As a further description of the above technical solution:
[0014] The mounting frame is fixedly connected to the side wall with two fixing brackets.
[0015] By adopting the above technical solution, the mounting bracket is used to provide an installation position for the second motor and the slide bar.

When drilling switchgear parts placed on the second processing table, the operator can remove the drilled switchgear parts from the first processing table and replace them with unprocessed switchgear parts. After the switchgear parts on the second processing table are processed, the first motor drives the drive sprocket to rotate, which in turn drives the chain drive, causing the second connecting block to move closer to the first motor. This, in turn, moves the first processing table closer to the first motor. Simultaneously, the chain drive moves the first connecting block away from the first motor, which in turn moves the sliding table away from the first motor. During this movement, the fixed rod is located at the guide groove. The guide groove causes the fixed rod to move downwards when it reaches the middle of the guide groove, which in turn causes the connector, connecting column, and second processing table to move downwards. This causes the second processing table and the first processing table to be offset at the center position. When the second processing table moves to the leftmost end, the first processing table moves to the rightmost end. At this time, the drill bit can directly process the switch cabinet parts on the first processing table. The operator can also remove the drilled switch cabinet parts from the second processing table and place new parts on them. The processing flow is faster and the drilling efficiency can be improved. Compared with the existing drilling device, when loading and unloading, it is necessary to wait for the current workpiece to be processed, manually disassemble → clean → clamp the new workpiece → reposition, and the single loading and unloading takes about 2-5 minutes. The idle time of the equipment accounts for as high as 40%-60%, which leads to poor drilling efficiency. This high and low voltage switch cabinet drilling device can shorten the loading and unloading time, thereby improving the drilling efficiency. Attached Figure Description

[0038] Reference Figure 1-6This utility model provides a drilling device for high and low voltage switchgear: It includes a mounting frame 1, with two first slide rails 2 fixedly connected to the upper surface of the mounting frame 1. A first processing table 3 is slidably mounted on the upper surface of the first slide rails 2. Two connecting plates 4 are fixedly connected to the inner bottom of the mounting frame 1. Two second slide rails 5 are fixedly connected to the upper surface of the connecting plates 4. A sliding table 6 is slidably mounted on the upper surface of the second slide rails 5. A second processing table 7 is provided above the sliding table 6. Four connecting columns 8 are fixedly connected to the lower surface of the second processing table 7.

A guide groove 13 is provided on the side wall of the fixing plate 12. The fixing rod 11 is located inside the guide groove 13. A first motor 14 is fixedly connected to the side wall of the mounting frame 1. A drive sprocket 15 is fixedly connected to the output end of the first motor 14. Five driven sprockets 16 are movably installed on the inner wall of the mounting frame 1. The drive sprockets 15 and the driven sprockets 16 are connected by a chain 17. A first connecting block 18 is fixedly connected to the outer wall of the chain 17. The first connecting block 18 is fixedly connected to the side wall of the sliding table 6. A second connecting block 19 is fixedly connected to the outer wall of the chain 17. The second connecting block 19 is fixedly connected to the lower surface of the first processing table 3. When drilling is being performed on the switch cabinet parts placed on the second processing table 7, the operator can remove the drilled switch cabinet parts from the first processing table 3 and place an unprocessed switch cabinet part on top. After the switch cabinet parts on the second processing table 7 are finished, the first motor 14 drives the drive sprocket 15 to rotate, which in turn drives the chain 17 to move the second connecting block 19 toward the first motor 14, thereby moving the first processing table 3 toward the first motor 14. At the same time, the chain 17 drives the first connecting block 18 to move away from the first motor 14, thereby moving the sliding table 6 away from the first motor 14. During the movement, because the fixed rod 11 is located in the guide groove 13, This causes the fixed rod 11 to move down when it moves to the middle of the guide groove 13, which in turn causes the connector 10, the connecting column 8, and the second processing table 7 to move down, so that the second processing table 7 and the first processing table 3 are offset at the center position. When the second processing table 7 moves to the leftmost end, the first processing table 3 moves to the rightmost end. At this time, the drill bit 33 can directly process the switch cabinet parts on the first processing table 3. The operator can also remove the drilled switch cabinet parts on the second processing table 7 and put new parts on it. The processing flow is faster and the drilling efficiency can be improved. The upper surface of the sliding table 6 is provided with a moving groove 9. There are four moving grooves 9. The connecting column 8 is located inside the moving groove 9. The moving groove 9 can provide space for the connecting column 8 to move.
[0039] A first chip collection box 20 is fixedly connected to the lower surface of the first processing table 3, and a second chip collection box 21 is fixedly connected to the lower surface of the second processing table 7. The first chip collection box 20 can collect the waste chips generated during drilling on the first processing table 3, and the second chip collection box 21 can collect the debris generated during drilling on the second processing table 7, facilitating subsequent manual cleaning of the debris. Two fixing frames 22 are fixedly connected to the side wall of the mounting frame 1. The fixing frames 22 provide mounting positions for the second motor 23 and the slide bar 26. The second motor 23 is fixedly connected to the side wall of the front fixing frame 22. A first lead screw 24 is fixedly connected to the output end of the second motor 23. A first sliding block 25 is threaded onto the outer surface of the first lead screw 24. The operation of the second motor 23 can drive the first lead screw 24 to rotate, thereby controlling the first sliding block 25 to move left and right, and thus driving the drill bit 33 to move left and right. A slide bar is fixedly connected to the inner wall of the rear fixing frame 22. 26. A first sliding block 25 is fitted on the outer surface of the slide rod 26. The slide rod 26 is used to support and limit the first sliding block 25. A third motor 27 is fixedly connected to the side wall of the first sliding block 25. A second lead screw 28 is fixedly connected to the output end of the third motor 27. A second sliding block 29 is threadedly connected to the outer surface of the second lead screw 28. When the third motor 27 is working, it can drive the second lead screw 28 to rotate, thereby driving the second sliding block 29 to move back and forth, and thus the drill bit 33 to move back and forth. A hydraulic cylinder 30 is fixedly connected to the lower surface of the second sliding block 29. A moving plate 31 is fixedly connected to the extended end of the hydraulic cylinder 30. A fourth motor 32 is fixedly connected to the lower surface of the moving plate 31. The drill bit 33 is fixedly connected to the output end of the fourth motor 32. When the hydraulic cylinder 30 is working, it can drive the moving plate 31 to move up and down, thereby driving the fourth motor 32 and the drill bit 33 to move up and down. When the fourth motor 32 is working, it can drive the drill bit 33 to rotate to drill.
[0040] Working principle: When drilling holes in the switch cabinet parts placed on the second processing table 7, the operator can remove the drilled switch cabinet parts from the first processing table 3 and place an unprocessed switch cabinet part on top. After the switch cabinet parts on the second processing table 7 are processed, the first motor 14 drives the drive sprocket 15 to rotate, which in turn drives the chain 17 to move the second connecting block 19 closer to the first motor 14, thereby moving the first processing table 3 closer to the first motor 14. At the same time, the chain 17 drives the first connecting block 18 to move away from the first motor 14, thereby moving the sliding table 6 away from the first motor 14. The device moves away from the first motor 14. During this movement, the fixed rod 11 is located in the guide groove 13, causing it to move downwards when it reaches the middle of the guide groove 13. This causes the connecting piece 10, the connecting column 8, and the second processing table 7 to move downwards, just enough to make the second processing table 7 and the first processing table 3 offset at the center position. When the second processing table 7 moves to the leftmost end, the first processing table 3 moves to the rightmost end. At this time, the drill bit 33 can directly process the switch cabinet parts on the first processing table 3. The operator can also remove the drilled switch cabinet parts from the second processing table 7 and put on new parts. The processing flow is faster and the drilling efficiency can be improved.
