Description

Technical Field

[0001] This invention relates to the field of drilling devices, and more particularly to a metal tube drilling device. Background Technology

[0002] In modern engineering and manufacturing, steel pipes are an indispensable material, widely used in construction, manufacturing, and various other fields. This is because steel pipes possess excellent strength, durability, and versatility, making them one of the core materials for many engineering projects. However, to meet the needs of different applications, steel pipes often need to be processed to change their shape and size for connection, fixing, or other specific purposes. One common processing requirement is drilling holes in the steel pipes.

[0003] Patent application number CN202320668786.9 discloses a steel pipe drilling machine, including a base and two clamping mechanisms. A steel pipe is arranged between the clamping mechanisms, and a drilling mechanism is arranged at the bottom of the steel pipe. The two ends of the steel pipe are fixed together by the clamping mechanisms. The drilling mechanism is used to drill holes in the steel pipe. However, this type of drilling machine cannot automatically rotate the steel pipe. When drilling holes in different positions of the steel pipe, it is necessary to manually rotate the steel pipe and then fix it again, resulting in low drilling efficiency.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a metal tube drilling device.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a metal tube drilling device, comprising a frame, on which a conveying screw and a slide rod are mounted. The conveying screw is driven to rotate by a conveying motor. A slide table is threadedly connected to the conveying screw, and the slide rod passes through and is slidably connected to the slide table. A support plate is fixed to the slide table, and a turntable rotatably connected to the support plate is mounted on the support plate. The turntable is driven to rotate by a rotary motor. Multiple fixing devices are evenly fixed to the turntable. Each fixing device includes a slide rail fixed to the turntable, a slider slidably connected to the corresponding slide rail on each slide rail, a fixing block fixed to each slider, and a fixing rod fixed to each slider. A fixing plate rotatably connected to the turntable is also mounted on the turntable. The fixed plate has arc-shaped grooves at positions corresponding to the fixed rods. The fixed rods pass through the grooves and are slidably connected to them. The fixed plate is driven to rotate by a fixed motor. A support block is also fixed on the frame. A limit block is provided above the support block. The limit block has a limit hole that penetrates the limit block. Hydraulic cylinders are fixed on the frame on both sides of the limit block. The piston rods of the hydraulic cylinders are fixed to the limit blocks. A lifting screw and a support rod are also provided on the frame. The lifting screw is driven to rotate by a lifting motor. A sliding plate is threadedly connected to the lifting screw. The support rod passes through the sliding plate and is slidably connected to it. A drilling motor is fixed on the sliding plate. A drill bit is fixed at the output end of the drilling motor.After the steel pipe to be drilled passes through the positioning tube and the support tube, and then through the fixing holes on the fixing plate and the turntable, the fixed motor drives the gear to rotate. Because the gear meshes with the arc-shaped rack on the fixing plate, the fixing plate rotates at a certain angle when the gear rotates. Since the sliding groove on the fixing plate has an arc structure, the fixing rod passes through the sliding groove and slides in connection with it. When the fixing plate rotates, the sliding groove drives the slider to move on the slide rail, and each fixing block moves closer to the steel pipe. After each fixing block contacts the steel pipe, it fixes the steel pipe. After the steel pipe is fixed by the fixing blocks, the conveying motor drives the conveying screw to rotate. During operation, the slide moves in the direction of the lead screw, the fixed block moves with the slide, and the steel pipe moves with the fixed block. When the position on the steel pipe to be drilled reaches directly below the drill bit, the hydraulic cylinder is activated, the piston rod on the hydraulic cylinder shortens, and the limit block moves, fixing the steel pipe to the support block. After the steel pipe is fixed, the drilling motor drives the drill bit to rotate at high speed, and the lifting motor drives the lifting lead screw to rotate. When the lifting lead screw rotates, the slide moves in the direction of the lifting lead screw, the drill bit descends, and after passing through the limit hole, the drill bit contacts the steel pipe to perform the drilling operation. After the steel pipe is drilled, the lifting motor drives the lifting lead screw to reverse. As the drill bit rotates, it rises and separates from the steel pipe. The hydraulic cylinder restarts, extending the piston rod and separating the limit block from the steel pipe. The conveyor motor then drives the conveyor screw to rotate, causing the steel pipe to move again. The next drilling position on the steel pipe is once again below the drill bit, and drilling is performed again. When the steel pipe needs to be rotated at a certain angle, the rotary motor drives the turntable to rotate by a certain angle. The fixed block rotates with the turntable, and the steel pipe rotates by a certain angle, moving the steel pipe back to the designated position for drilling again. Furthermore, as the slide moves forward... After a certain distance, the steel pipe is fixed by the limiting blocks, and the fixed motor drives the gear to rotate in the opposite direction by a certain angle, separating each fixing block from the steel pipe. Then, the conveying motor drives the conveying screw to rotate in the opposite direction, and the slide moves away from the drill bit. When the slide moves to the appropriate position, the steel pipe is fixed again by the fixing blocks, and the steel pipe is moved again to meet the drilling needs of longer steel pipes. This device can perform drilling operations at multiple positions on the steel pipe and can rotate the steel pipe by a certain angle to meet the drilling needs of different positions on the steel pipe, and it can also meet the drilling needs of longer steel pipes.

[0008] Preferably, baffles are fixed obliquely on the frame above the conveying screw and slide bar.

[0009] Preferably, a main pulley is fixed at the output end of the rotary motor, and a driven pulley is fixed on the turntable. The driven pulley is connected to the main pulley via a synchronous belt.

[0010] Preferably, the fixing block has an arc-shaped structure. The arc-shaped fixing block increases the contact area with the steel pipe.

[0011] Preferably, a positioning tube is fixed on one side of the frame of the slide table, and a support tube is fixed on one side of the frame of the support block. The positioning tube and the support tube provide positioning and support for the steel pipe.

[0012] Preferably, a water spray pipe is also fixed on the frame on one side of the drill bit, and the end of the water spray pipe is connected to a water pump in the water tank. When the drill bit drills a hole in the steel pipe, water is sprayed onto the drill bit through the water spray pipe to cool it down and prevent the drill bit from being damaged by overheating.

[0013] Preferably, a water receiving tray is also fixed on the frame below the support block, and the bottom of the water receiving tray is connected to a collection box via a water pipe. Cooling water falls into the water receiving tray and is collected.

[0014] Preferably, a gear is fixed to the output end of the fixed motor, and an arc-shaped rack is fixed to the fixed plate, the rack meshing with the gear.

[0015] Compared with existing technologies, the present invention has the following advantages:

[0016] This device can perform drilling operations at multiple locations on a steel pipe, and can rotate the steel pipe at a certain angle to meet the drilling needs at different locations on the steel pipe, and can also meet the drilling needs of longer steel pipes. Attached Figure Description

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0025] Example 1:

[0026] like Figures 1 to 5As shown, this embodiment discloses a metal tube drilling device, including a frame 1. A lead screw 2 and a slide bar 3 are mounted on the frame 1. The lead screw 2 is driven to rotate by a conveying motor 5. A slide table 6 is threadedly connected to the lead screw 2. The slide bar 3 passes through the slide table 6 and is slidably connected to the slide table 6. A support plate 7 is fixed on the slide table 6. A turntable 8 is rotatably connected to the support plate 7. The turntable 8 is driven to rotate by a rotary motor 20. Multiple fixing devices 9 are evenly fixed on the turntable 8. Each fixing device 9 includes a slide rail 10 fixed on the turntable 8. Each slide rail 10 has a slider 11 slidably connected to the corresponding slide rail 10. Each slider 11 has a fixing block 12 fixed on it. Each slider 11 has a fixing rod 13 fixed on it. The turntable 8 also has a fixing plate 14 rotatably connected to it. The fixing plate 14 is connected to the fixing rod 13. 3. Arc-shaped grooves 16 are provided at corresponding positions. The fixing rod 13 passes through the grooves 16 at the corresponding positions and is slidably connected to the grooves 16. The fixing plate 14 is driven to rotate by the fixing motor 18. The frame 1 is also fixed with a support block 26. A limit block 27 is provided above the support block 26. A limit hole 28 is provided on the limit block 27. Hydraulic cylinders 29 are fixed on both sides of the frame 1. The piston rod ends of the hydraulic cylinders 29 are fixed to the limit block 27. The frame 1 is also provided with a lifting screw 30 and a support rod 31. The lifting screw 30 is driven to rotate by the lifting motor 32. A sliding plate 33 is provided on the lifting screw 30 and is threadedly connected to the lifting screw 30. The support rod 31 passes through the sliding plate 33 and is slidably connected to the sliding plate 33. A drilling motor 34 is fixed on the sliding plate 33. A drill bit 35 is fixed at the output end of the drilling motor 34.After the steel pipe to be drilled passes through the positioning tube 24 and the support tube 25, and then through the fixing plate 14 and the fixing hole 15 on the turntable 8, the fixed motor 18 drives the gear 19 to rotate. Since the gear 19 meshes with the arc-shaped rack 17 on the fixed plate 14, the fixed plate 14 rotates a certain angle when the gear 19 rotates. Since the slide groove 16 on the fixed plate 14 has an arc structure, the fixing rod 13 passes through the slide groove 16 and slides in connection with the slide groove 16. When the fixed plate 14 rotates, the slide groove 16 drives the slider 11 to move on the slide rail 10. Each fixing block 12 moves closer to the steel pipe. After each fixing block 12 contacts the steel pipe, it fixes the steel pipe. After the steel pipe is fixed by the fixing blocks 12, it is transported by the conveyor belt. The motor 5 drives the conveying screw 2 to rotate. When the conveying screw 2 rotates, the slide table 6 moves in the direction of the conveying screw 2, and the fixing block 12 moves with the slide table 6. The steel pipe moves with the fixing block 12. When the position to be drilled on the steel pipe reaches directly below the drill bit 35, the hydraulic cylinder 29 is activated. The piston rod on the hydraulic cylinder 29 shortens, and the limit block 27 moves. The limit block 27 fixes the steel pipe on the support block 26. After the steel pipe is fixed, the drilling motor 34 drives the drill bit 35 to rotate at high speed, and the lifting motor 32 drives the lifting screw 30 to rotate. When the lifting screw 30 rotates, the slide plate 33 moves in the direction of the lifting screw 30, and the drill bit 35 descends. After the drill bit 35 passes through the limit hole 28, it contacts the steel pipe. Drilling is performed on the steel pipe. After drilling is completed, the lifting motor 32 drives the lifting screw 30 to rotate in the opposite direction, the drill bit 35 rises and separates from the steel pipe, the hydraulic cylinder 29 starts again, the piston rod on the hydraulic cylinder 29 extends, the limit block 27 separates from the steel pipe, and the conveying motor 5 drives the conveying screw 2 to rotate again, the steel pipe moves again, and the next drilling position on the steel pipe reaches below the drill bit 35 again, and the drilling operation on the steel pipe is performed again. When it is necessary to rotate the steel pipe to a certain angle, the rotary motor 20 drives the turntable 8 to rotate to a certain angle, the fixing block 12 rotates with the turntable 8, the steel pipe rotates to a certain angle, and the steel pipe is moved to the designated position again, and the steel pipe is drilled again. The operation involves moving the slide 6 forward a certain distance, then fixing the steel pipe with the limit block 27, and driving the gear 19 to rotate in the opposite direction by the fixed motor 18, separating each fixed block 12 from the steel pipe. Then, the conveying motor 5 drives the conveying screw 2 to rotate in the opposite direction, moving the slide 6 away from the drill bit 35. When the slide 6 moves to the appropriate position, the steel pipe is fixed again with the fixed block 12, and the steel pipe is moved again to meet the drilling requirements of longer steel pipes. This device can perform drilling operations at multiple positions on the steel pipe and can rotate the steel pipe at a certain angle to meet the drilling requirements of different positions on the steel pipe, and it can also meet the drilling requirements of longer steel pipes.

[0027] Both the lead screw 2 and the slide bar 3 are equipped with inclined baffles 4 on the frame 1. The baffles 4 prevent dust and metal shavings from falling onto the lead screw 2.

[0028] Among them, the output end of the rotary motor 20 is fixed with a main pulley 21, and the turntable 8 is fixed with a driven pulley 22. The driven pulley 22 is connected to the main pulley 21 through a synchronous belt 23.

[0029] The fixing block 12 has an arc-shaped structure. The arc shape of the fixing block 12 increases the contact area with the steel pipe.

[0030] A positioning tube 24 is fixed on the frame 1 on one side of the slide table 6, and a support tube 25 is fixed on the frame 1 on one side of the support block 26. The positioning tube 24 and the support tube 25 provide positioning and support for the steel pipe.

[0031] Among them, a gear 19 is fixed at the output end of the fixed motor 18, and an arc-shaped rack 17 is fixed on the fixed plate 14, with the rack 17 meshing with the gear 19.

[0033] This embodiment discloses a metal pipe drilling device. Based on the structure and principle of Embodiment 1, this embodiment also has a water spray pipe 36 fixed on the frame 1 on one side of the drill bit 35. The end of the water spray pipe 36 is connected to a water pump in a water tank. When the drill bit 35 drills a hole in a steel pipe, water is sprayed onto the drill bit 35 through the water spray pipe 36 to cool the drill bit 35 and prevent it from being damaged by overheating.

[0034] A water collection tray 37 is fixed on the frame 1 below the support block 26, and the bottom of the water collection tray 37 is connected to the collection box through a water pipe. Cooling water falls into the water collection tray 37 and is collected.
