Description

Technical Field

[0001] This invention relates to the field of flange processing, specifically to a fully automatic flange processing device. Background Technology

[0002] A flange is a disc-shaped part, usually used in pairs. There are bolt holes on the flange. The two flanges are installed on both sides of the interface of the pipe or equipment to be connected, and the bolt holes are aligned. Then, a gasket is inserted between the flanges, and finally the bolts are tightened. When tightening the bolts, the force should be applied evenly in the diagonal direction to deform the gasket and fill the tiny gaps on the flange sealing surface, thereby achieving the purpose of sealing.

[0003] Flange processing is the process of turning raw materials into pipe connection parts that meet specifications. The core is to ensure dimensional accuracy and sealing performance. Before processing, raw materials such as carbon steel and stainless steel are selected according to the working conditions. The materials are cut by flame cutting, forging and other methods, leaving machining allowance. The forged blanks need to be annealed to eliminate internal stress. The core process is divided into roughing and finishing. Roughing is done on a lathe to turn the end face, outer circle and inner hole to remove most of the allowance. Finishing focuses on precision turning the sealing surface to ensure the roughness and flatness requirements. Then, the bolt holes are machined by a drilling machine to ensure positional accuracy and indexing accuracy.

[0004] The flange surface has several through holes for mounting bolts for fixing. In the existing technology, during the processing of the flange, drilling operations are required. First, the drilling positions of the flange are marked, and then the positions are adjusted one by one before drilling. However, the position adjustment process is mostly done manually, which is prone to certain errors. Moreover, before adjusting the position, the flange limit needs to be contacted, and after adjustment, it needs to be fixed again. The above operations result in low flange processing efficiency. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a fully automatic flange processing device to solve the technical problems mentioned above in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic flange processing device, comprising a device body, an installation chamber, and a limiting column, wherein the installation chamber is provided at the upper end of the device body, and the limiting column is movably installed inside the installation chamber; The limiting post has multiple sets of movable cylinders movably installed inside, and these sets of movable cylinders are staggered. Each set of movable cylinders has a telescopic post movably installed on its inner wall, and the outer walls of the telescopic posts are threadedly connected to the inner walls of the movable cylinders. The limiting post has multiple sets of limiting plates movably installed on its outer wall, and one end of each limiting plate is connected to one end of each telescopic post. The limiting plates can synchronously move radially to limit movement from the inner wall of the flange. The main body of the device has a first connecting shaft movably installed inside. The center end of the first connecting shaft is provided with a one-way bearing. One end of the first connecting shaft is linked to the subsequent transmission structure through a toothed synchronous belt, and the other end of the first connecting shaft is connected to the limiting post through gear meshing. The device body is equipped with a mounting frame on its upper end, and a first drive motor is mounted on the upper end of the mounting frame. A first drive shaft is mounted on the output end of the first drive motor. A movable column is mounted on the outer wall of the first drive shaft, and the outer wall of the first drive shaft is threadedly connected to the inner wall of the movable column. A drilling device is mounted on one end of the movable column, and a connecting rod is mounted on the outer wall of the movable column. The connecting rod is linked to the first connecting shaft through a gear transmission mechanism via a toothed plate.

[0007] By adopting the above technical solution, the problem of low flange processing efficiency is solved. The flange is placed on the outer end of the limiting post, and multiple sets of limiting plates cooperate to fix the flange from the inner wall. After the drilling operation is completed at one end of the flange, the drilling device moves upward, driving the limiting post to rotate, which in turn drives the multiple sets of limiting plates to rotate, so that the flange rotates around the limiting post as the center, thereby adjusting the flange drilling position. The other end of the flange moves to the lower end of the drilling device, improving the convenience of adjusting the flange drilling area, thereby improving the flange processing efficiency and reducing the workload of the workers.

[0008] The invention is further configured such that a second drive motor is installed inside the limiting column, a second drive shaft is installed at the output end of the second drive motor, and multiple sets of drive bevel gears are installed on the outer wall of the second drive shaft. Each of the multiple sets of movable cylinders has a second movable bevel gear installed at one end. The multiple sets of movable cylinders are linked sequentially by a toothed synchronous belt to achieve synchronous rotation of the multiple sets of movable cylinders. The inner walls of the multiple sets of movable cylinders are threadedly connected to the outer walls of the corresponding telescopic columns to drive the multiple sets of limiting plates to synchronously rotate radially.

[0009] Preferably, the second drive motor starts, driving the second drive shaft to rotate, which in turn drives multiple sets of drive bevel gears to rotate. These multiple sets of drive bevel gears mesh with multiple sets of second movable bevel gears, causing them to rotate. This, in turn, drives multiple sets of movable cylinders, which are connected to each other via toothed synchronous belts. The inner walls of these movable cylinders are threadedly connected to the outer walls of multiple sets of telescopic columns, causing them to move. This displacement of the telescopic columns, in turn, drives multiple sets of limiting plates to move. These limiting plates cooperate to limit and fix the flange.

[0010] The present invention is further configured such that a toothed plate is installed at one end of the connecting rod, and a transmission shaft is movably installed inside the main body of the device via a bearing. A transmission gear and a transmission bevel gear are respectively installed at both ends of the transmission shaft, and the transmission gear is meshed with the toothed plate.

[0011] Preferably, the connecting rod moves downward, causing the toothed plate to move downward. The toothed plate meshes with the transmission gear, causing the transmission gear to rotate, which in turn drives the transmission shaft to rotate, and then drives the transmission bevel gear to rotate.

[0012] The present invention is further configured such that a movable shaft is movably mounted below the transmission shaft inside the main body of the device via a bearing, a first movable bevel gear is mounted on the upper end of the movable shaft, and the first movable bevel gear is meshed with the transmission bevel gear, and a toothed synchronous belt is provided at one end of the movable shaft to connect the first linkage shaft.

[0013] Preferably, the transmission bevel gear rotates and meshes with the first movable bevel gear, so the first movable bevel gear rotates, thereby driving the movable shaft to rotate. The movable shaft is connected to the first connecting shaft through a toothed synchronous belt, so one end of the first connecting shaft rotates.

[0014] The present invention is further configured such that a connecting gear is installed at the other end of the first connecting shaft, a limiting gear is installed on the outer wall of the limiting post, and the limiting gear is meshed with the connecting gear.

[0015] Preferably, the other end of the first connecting shaft rotates, thereby driving the connecting gear to rotate. The connecting gear meshes with the limiting gear, thereby driving the limiting post to rotate.

[0016] The present invention is further configured such that multiple sets of mounting boxes are movably installed inside the main body of the device corresponding to the outer area of ​​the flange, and multiple sets of second connecting shafts are movably installed inside the main body of the device via bearings. One set of second connecting shafts is connected to the movable shaft via a toothed synchronous belt, and the multiple sets of second connecting shafts are sequentially linked by toothed synchronous belts. The ends of the multiple sets of second connecting shafts away from the movable shaft extend into the interior of the multiple sets of mounting boxes, and each end is fixedly installed with a connecting bevel gear.

[0017] Preferably, the movable shaft rotates, and the movable shaft and a set of second connecting shafts are connected by toothed synchronous belts. Thus, when a set of second connecting shafts rotates, multiple sets of second connecting shafts are connected by toothed synchronous belts, thus driving multiple sets of connecting bevel gears to rotate.

[0018] The present invention is further configured such that each of the multiple sets of mounting boxes has a limiting shaft and a telescopic rod movably installed inside, and the outer walls of the multiple sets of limiting shafts are threadedly connected to the inner walls of the multiple sets of telescopic rods. Each of the multiple sets of limiting shafts has a limiting bevel gear installed at one end, and the multiple sets of limiting bevel gears are meshed with multiple sets of connecting bevel gears. Each of the multiple sets of telescopic rods has a clamping plate installed at one end of the outer wall of the multiple sets of mounting boxes.

[0019] Preferably, multiple sets of linkage bevel gears rotate, and the multiple sets of linkage bevel gears are respectively meshed with multiple sets of limiting bevel gears. Therefore, the multiple sets of limiting bevel gears rotate, thereby driving multiple sets of limiting shafts to rotate. The outer walls of the multiple sets of limiting shafts are respectively threadedly connected to the inner walls of multiple sets of telescopic rods. Therefore, the multiple sets of telescopic rods are displaced, thereby driving multiple sets of clamping plates to displace.

[0020] The present invention is further configured such that the clamping surfaces of the multiple sets of limiting plates and the multiple sets of clamping plates are provided with an anti-slip buffer layer, wherein the anti-slip buffer layer is one of a rubber pad layer, a silicone pad layer or a polyurethane pad layer.

[0021] Preferably, multiple sets of limiting plates and multiple sets of clamping plates work together to clamp and fix the flange, and the anti-slip buffer layer further improves the stability of the flange after clamping and fixing.

[0022] The invention is further configured such that a material discharge trough is provided at the upper end of the main body of the device, a dust collection box is installed inside the main body of the device, and an air pump is provided inside the dust collection box. A first suction pipe and a second suction pipe are installed at the dust collection port of the dust collection box. A first bracket and a second bracket are installed at the upper end of the main body of the device. A first suction plate is installed at one end of the first bracket, and one end of the first suction pipe is connected to the first suction plate. A second suction plate is installed at one end of the material discharge trough, and one end of the second suction pipe is connected to one end of the second suction plate.

[0023] Preferably, the air pump inside the dust collection box is activated, which generates suction inside the first and second suction pipes, thereby generating suction on the first and second suction plates. The first suction plate absorbs the dust and debris generated by the drilling device drilling the flange. After the drilling device drills a hole at one end of the flange, some of the dust and debris falls into the material chute, where the second suction plate absorbs the dust.

[0024] The present invention is further configured such that a first air outlet pipe and a second air outlet pipe are installed at the air outlet of the dust collection box, a first air outlet plate is installed at one end of the second bracket, and one end of the first air outlet pipe is connected to the first air outlet plate, and a second air outlet plate is installed at the other end of the material discharge chute, and one end of the second air outlet pipe is connected to the second air outlet plate.

[0025] Preferably, the dust collection box discharges airflow through the first air outlet pipe and the second air outlet pipe respectively, and then the airflow is discharged through the first air outlet plate and the second air outlet plate. The first air outlet plate cleans the drilled holes of the flange, so that the residual waste on the inner wall of the flange hole falls into the material discharge trough. Then the second air outlet plate blows the waste inside the material discharge trough to the area of ​​the second dust collection plate, improving the convenience of waste absorption inside the material discharge trough.

[0026] In summary, the present invention has the following main beneficial effects: 1. This invention solves the problem of low flange processing efficiency by setting a limiting post and limiting plates. The flange is placed on the outer end of the limiting post, and multiple sets of limiting plates cooperate to fix the flange from the inner wall. After the drilling operation is completed at one end of the flange, the drilling device moves upward, driving the limiting post to rotate, thereby driving the multiple sets of limiting plates to rotate, so that the flange rotates around the limiting post as the center, thereby adjusting the drilling position of the flange. The other end of the flange moves to the lower end of the drilling device, improving the convenience of adjusting the drilling area of ​​the flange, thereby improving the flange processing efficiency and reducing the workload of the workers.

[0027] 2. This invention comprises a material discharge trough, a dust collection box, a first dust suction plate, a second dust suction plate, a first air outlet plate, and a second air outlet plate. When the air pump inside the dust collection box is activated, suction is generated inside the first and second dust suction pipes, which in turn generates suction on the first and second dust suction plates. The first dust suction plate absorbs the dust and debris generated by the drilling device during the drilling operation on the flange. After the drilling device drills a hole at one end of the flange, some of the dust and debris falls into the material discharge trough. The second dust suction plate then collects the dust from inside the material discharge trough. After the flange drilling position is adjusted, the drilling device moves downward to drill holes at the other end of the flange. At the same time, the dust collection box discharges airflow through the first and second air outlet pipes. The airflow then passes through the first and second air outlet plates. The first air outlet plate cleans the drilled holes on the flange, causing residual debris inside the holes to fall into the material chute. The second air outlet plate then blows the debris from the material chute to the second dust collection plate area, improving the convenience of debris absorption inside the material chute.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of the present invention will now be described.

[0032] Please refer to a fully automated flange processing device. Figure 1 - Figure 8 The device includes a main body 1, an installation chamber 17, and a limiting post 18. The installation chamber 17 is provided at the upper end of the main body 1, and the limiting post 18 is movably installed inside the installation chamber 17. Multiple sets of movable cylinders 23 are movably installed inside the limiting column 18, and the multiple sets of movable cylinders 23 are staggered. Telescopic columns 25 are movably installed on the inner walls of the multiple sets of movable cylinders 23, and the outer walls of the multiple sets of telescopic columns 25 are threadedly connected to the inner walls of the multiple sets of movable cylinders 23. Multiple sets of limiting plates 26 are movably installed on the outer wall of the limiting column 18, and one end of the multiple sets of limiting plates 26 is connected to one end of the multiple sets of telescopic columns 25. The multiple sets of limiting plates 26 can synchronously move radially to limit from the inner wall of the flange. A first connecting shaft 14 is movably installed inside the main body 1 of the device. A one-way bearing 15 is provided at the center end of the first connecting shaft 14. One end of the first connecting shaft 14 is linked to the subsequent transmission structure through a toothed synchronous belt, and the other end of the first connecting shaft 14 is connected to the limiting column 18 through gear meshing. A mounting bracket 2 is installed on the upper end of the main body 1 of the device. A first drive motor 3 is installed on the upper end of the mounting bracket 2. A first drive shaft 4 is installed on the output end of the first drive motor 3. A movable column 5 is installed on the outer wall of the first drive shaft 4, and the outer wall of the first drive shaft 4 is threadedly connected to the inner wall of the movable column 5. A drilling device 6 is installed on one end of the movable column 5. A connecting rod 7 is installed on the outer wall of the movable column 5, and the connecting rod 7 is linked to the first connecting shaft 14 through a toothed plate and gear transmission mechanism.

[0033] Please see Figure 4 - Figure 5 A second drive motor 20 is installed inside the limiting post 18. A second drive shaft 21 is installed at the output end of the second drive motor 20. Multiple sets of drive bevel gears 22 are installed on the outer wall of the second drive shaft 21. Each of the multiple sets of movable cylinders 23 has a second movable bevel gear 24 installed at one end. The multiple sets of movable cylinders 23 are linked sequentially by a toothed synchronous belt to achieve synchronous rotation of the multiple sets of movable cylinders 23. The inner walls of the multiple sets of movable cylinders 23 are threaded to the outer walls of the corresponding telescopic posts 25 to drive the multiple sets of limiting plates 26 to synchronously move radially. The second drive motor 20 is started, driving the second drive shaft 21 to rotate. This causes multiple sets of drive bevel gears 22 to rotate. The multiple sets of drive bevel gears 22 are respectively engaged with multiple sets of second movable bevel gears 24. Therefore, the multiple sets of second movable bevel gears 24 rotate, thereby driving multiple sets of movable cylinders 23. The multiple sets of movable cylinders 23 are respectively connected by toothed synchronous belts, so the multiple sets of movable cylinders 23 rotate. The inner walls of the multiple sets of movable cylinders 23 are respectively threaded to the outer walls of multiple sets of telescopic columns 25, so the multiple sets of telescopic columns 25 are displaced, thereby driving multiple sets of limiting plates 26 to displace. The multiple sets of limiting plates 26 cooperate to limit and fix the flange.

[0034] Please see Figure 4A toothed plate 8 is installed at one end of the connecting rod 7. A transmission shaft 9 is movably installed inside the main body 1 via bearings. A transmission gear 10 and a transmission bevel gear 11 are respectively installed at both ends of the transmission shaft 9. The transmission gear 10 is meshed with the toothed plate 8. When the connecting rod 7 moves downward, it causes the toothed plate 8 to move downward. The toothed plate 8 meshes with the transmission gear 10, so the transmission gear 10 rotates, thereby driving the transmission shaft 9 to rotate, and then driving the transmission bevel gear 11 to rotate.

[0035] Please see Figure 4 - Figure 6 Inside the main body 1 of the device, a movable shaft 12 is movably mounted below the transmission shaft 9 via a bearing. A first movable bevel gear 13 is mounted on the upper end of the movable shaft 12, and the first movable bevel gear 13 is meshed with the transmission bevel gear 11. The movable shaft 12 is connected to one end of the first connecting shaft 14 by a toothed synchronous belt. When the transmission bevel gear 11 rotates, it meshes with the first movable bevel gear 13, thus causing the first movable bevel gear 13 to rotate, thereby driving the movable shaft 12 to rotate. The movable shaft 12 is connected to the first connecting shaft 14 via a toothed synchronous belt, so one end of the first connecting shaft 14 rotates.

[0036] Please see Figure 4 A connecting gear 16 is installed at the other end of the first connecting shaft 14, and a limiting gear 19 is installed on the outer wall of the limiting post 18. The limiting gear 19 is meshed with the connecting gear 16. The other end of the first connecting shaft 14 rotates, thereby driving the connecting gear 16 to rotate. The connecting gear 16 is meshed with the limiting gear 19, thereby driving the limiting post 18 to rotate.

[0037] Please see Figure 4 - Figure 6 Multiple mounting boxes 27 are movably installed inside the main body 1, corresponding to the outer area of ​​the flange. Multiple sets of second connecting shafts 28 are movably installed inside the main body 1 via bearings. One set of second connecting shafts 28 is connected to the movable shaft 12 via a toothed synchronous belt. The multiple sets of second connecting shafts 28 are linked sequentially via toothed synchronous belts. The ends of the multiple sets of second connecting shafts 28 away from the movable shaft 12 extend into the multiple sets of mounting boxes 27, and each end is fixedly installed with a connecting bevel gear 29. When the movable shaft 12 rotates, the movable shaft 12 is connected to the set of second connecting shafts 28 via toothed synchronous belts. Therefore, when the set of second connecting shafts 28 rotates, the multiple sets of second connecting shafts 28 are connected to each other via toothed synchronous belts, thus driving the multiple sets of connecting bevel gears 29 to rotate.

[0038] Please see Figure 6 - Figure 7Each of the multiple mounting boxes 27 has a movably mounted limiting shaft 30 and a telescopic rod 32. The outer walls of the multiple limiting shafts 30 are threadedly connected to the inner walls of the multiple telescopic rods 32. Each of the multiple limiting shafts 30 has a limiting bevel gear 31 installed at one end, and the multiple limiting bevel gears 31 are meshed with multiple connecting bevel gears 29. Each of the multiple telescopic rods 32 has a clamping plate 33 installed at one end of the outer wall of the multiple mounting boxes 27. When the multiple connecting bevel gears 29 rotate, they mesh with the multiple limiting bevel gears 31. Therefore, when the multiple limiting bevel gears 31 rotate, they drive the multiple limiting shafts 30 to rotate. Since the outer walls of the multiple limiting shafts 30 are threadedly connected to the inner walls of the multiple telescopic rods 32, the multiple telescopic rods 32 are displaced, which in turn drives the multiple clamping plates 33 to displace.

[0039] Please see Figure 4 - Figure 7 The clamping surfaces of the multiple sets of limiting plates 26 and multiple sets of clamping plates 33 are all provided with anti-slip buffer layers. The anti-slip buffer layers are one of rubber pads, silicone pads or polyurethane pads. The multiple sets of limiting plates 26 and multiple sets of clamping plates 33 work together to clamp and fix the flange. The setting of the anti-slip buffer layers further improves the stability of the flange after clamping and fixing.

[0040] Please see Figure 2 - Figure 8 The device body 1 has a material discharge chute 34 at its upper end. A dust collection box 37 is installed inside the device body 1, and an air pump is installed inside the dust collection box 37. A first suction pipe 38 and a second suction pipe 40 are installed at the dust collection port of the dust collection box 37. A first bracket 35 and a second bracket 36 are installed at the upper end of the device body 1. A first suction plate 39 is installed at one end of the first bracket 35, and one end of the first suction pipe 38 is connected to the first suction plate 39. A second suction plate 41 is installed at one end of the material discharge chute 34, and one end of the second suction pipe 40... Connected to one end of the second suction plate 41, the air pump inside the dust collection box 37 is started, causing suction to be generated inside the first suction pipe 38 and the second suction pipe 40, thereby generating suction on the first suction plate 39 and the second suction plate 41. The first suction plate 39 absorbs the dust and debris generated by the drilling device 6 drilling the flange. After the drilling device 6 drills a hole at one end of the flange, some of the dust and debris falls into the material chute 34, and the second suction plate 41 absorbs the dust inside the material chute 34.

[0041] Please see Figure 2 - Figure 8The dust collection box 37 is equipped with a first air outlet pipe 42 and a second air outlet pipe 44 at its air outlet. A first air outlet plate 43 is installed at one end of the second bracket 36, and one end of the first air outlet pipe 42 is connected to the first air outlet plate 43. A second air outlet plate 45 is installed at the other end of the material discharge chute 34, and one end of the second air outlet pipe 44 is connected to the second air outlet plate 45. The dust collection box 37 discharges airflow through the first air outlet pipe 42 and the second air outlet pipe 44 respectively. Then, the airflow is discharged through the first air outlet plate 43 and the second air outlet plate 45. The first air outlet plate 43 cleans the drilled holes of the flange, so that the residual waste on the inner wall of the flange hole falls into the material discharge chute 34. Then, the second air outlet plate 45 blows the waste inside the material discharge chute 34 to the area of ​​the second dust suction plate 41, improving the convenience of waste absorption inside the material discharge chute 34.

[0042] The working principle of this invention is as follows: When the operator uses this device to process the flange, the operator places the flange material on the upper end of the device body 1, and the center area of ​​the flange is placed on the outer end of the limiting column 18. Then, the second drive motor 20 is started, driving the second drive shaft 21 to rotate, thereby driving multiple sets of drive bevel gears 22 to rotate. The multiple sets of drive bevel gears 22 are respectively meshed with multiple sets of second movable bevel gears 24, so the multiple sets of second movable bevel gears 24 rotate, thereby driving multiple sets of movable cylinders 23. The multiple sets of movable cylinders 23 are respectively connected by toothed synchronous belts, so the multiple sets of movable cylinders 23 rotate. The inner walls of the multiple sets of movable cylinders 23 are respectively threaded to the outer walls of multiple sets of telescopic columns 25, so the multiple sets of telescopic columns 25 are displaced, thereby driving multiple sets of limiting plates 26 to displace. The multiple sets of limiting plates 26 cooperate to limit and fix the flange. After the flange is fixed in place, the first drive motor 3 and the air pump inside the dust collection box 37 are started, which drives the first drive shaft 4 to rotate. The outer wall of the first drive shaft 4 is threadedly connected to the inner wall of the movable column 5, so the movable column 5 moves downward, thereby driving the drilling device 6 and the connecting rod 7 to move downward, and then driving the toothed plate 8 to move downward. When the toothed plate 8 moves downward, it meshes with the transmission gear 10, causing the transmission gear 10 to rotate. This rotation drives the transmission shaft 9 to rotate, which in turn drives the transmission bevel gear 11 to rotate. The transmission bevel gear 11 meshes with the first movable bevel gear 13, causing the first movable bevel gear 13 to rotate. This rotation drives the movable shaft 12 to rotate. The movable shaft 12 is connected to the first connecting shaft 14 and a set of second connecting shafts 28 via toothed synchronous belts. Therefore, one end of the first connecting shaft 14 and the set of second connecting shafts 28 rotate. When the toothed plate 8 moves downward, it drives the end of the first connecting shaft 14 close to the movable shaft 12 to rotate. However, due to the one-way locking characteristic of the one-way bearing 15, the end of the first connecting shaft 14 away from the movable shaft 12 does not rotate. When the toothed plate 8 moves upward, the one-way bearing 15 unlocks, and the end of the first connecting shaft 14 away from the movable shaft 12 rotates synchronously with the other end. When a set of second linkage shafts 28 rotates, multiple sets of second linkage shafts 28 are connected to each other by toothed synchronous belts. Therefore, the rotation of multiple sets of second linkage shafts 28 drives multiple sets of linkage bevel gears 29 to rotate. The multiple sets of linkage bevel gears 29 are respectively engaged with multiple sets of limiting bevel gears 31. Therefore, the rotation of multiple sets of limiting bevel gears 31 drives multiple sets of limiting shafts 30 to rotate. The outer walls of multiple sets of limiting shafts 30 are respectively threaded to the inner walls of multiple sets of telescopic rods 32. Therefore, the multiple sets of telescopic rods 32 are displaced, thereby driving multiple sets of clamping plates 33 to displace. The multiple sets of clamping plates 33 synchronously approach the flange radially and clamp and fix it from the outer wall of the flange, further improving the stability of the flange. After the flange is further limited and fixed, the movable column 5 drives the drilling device 6 to continue to move downward, and the drilling device 6 performs drilling operations on the flange. When the air pump inside the dust collection box 37 is started, it generates suction inside the first suction pipe 38 and the second suction pipe 40, which in turn generates suction inside the first suction plate 39 and the second suction plate 41. The first suction plate 39 absorbs the dust and debris generated by the drilling device 6 drilling the flange. After the drilling device 6 drills a hole at one end of the flange, some of the dust and debris falls into the material chute 34. The second suction plate 41 absorbs the dust inside the material chute 34. After the drilling operation is completed at one end of the flange, the first drive motor 3 drives the first drive shaft 4 to rotate in the opposite direction, thereby causing the movable column 5 and the drilling device 6 to move upward, thereby causing the connecting rod 7 and the toothed plate 8 to move upward, and then causing the multiple sets of clamping plates 33 to move, releasing the limiting and fixing of the multiple sets of clamping plates 33 on the flange. When the toothed plate 8 moves upward, it drives the other end of the first connecting shaft 14 to rotate, thereby driving the connecting gear 16 to rotate. The connecting gear 16 meshes with the limiting gear 19, thereby driving the limiting post 18 to rotate, which in turn drives multiple sets of limiting plates 26 to rotate, and then drives the flange to rotate around the limiting post 18 as the center, thereby adjusting the flange drilling position. The other end of the flange moves to the lower end of the drilling device 6, and at the same time, the already drilled area of ​​the flange moves to the lower end of the first air outlet plate 43. After the flange drilling position is adjusted, the drilling device 6 moves downward to drill holes at the other end of the flange. At the same time, the dust collection box 37 discharges air through the first air outlet 42 and the second air outlet 44 respectively. Then the air is discharged through the first air outlet plate 43 and the second air outlet plate 45. The first air outlet plate 43 cleans the drilled holes of the flange, so that the residual waste on the inner wall of the flange hole falls into the material discharge trough 34. Then the second air outlet plate 45 blows the waste inside the material discharge trough 34 to the area of ​​the second dust suction plate 41, improving the convenience of waste absorption inside the material discharge trough 34.
