Technical Field
[0001] This utility model relates to the field of drilling device technology, and in particular to a drilling device for pipes used in bicycle production. Background Technology
[0002] Bicycles, also known as pedal bikes or bicycles, are usually small two-wheeled land vehicles. Bicycle production is a systematic project involving design, material selection, component manufacturing, assembly, quality inspection and final sales. The tubing used in bicycle production is a key material that constitutes the core structure of the frame, fork and other components. Its performance directly affects the weight, rigidity, comfort and durability of the bicycle. In the process of bicycle production, the bicycle tubing also needs to be drilled.
[0003] In existing technologies, drilling devices are mostly designed to clamp the tube externally to fix it. However, in scenarios where drilling is required at multiple angles, each time the drilling angle is changed, the fixed tube must be disassembled, rotated to the required angle, and then re-clamped. This cumbersome process not only significantly reduces drilling efficiency and increases production cycle and cost, but also makes it difficult to ensure that the tube is accurately fixed in the same position each time during multiple disassembly and re-clamping. In other words, it cannot be guaranteed that the re-clamped tube will remain concentric with the previous clamping, which may affect drilling accuracy and product quality. Therefore, it is necessary to improve the tube drilling device for bicycle production to solve the above problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figure 1 - Figure 6 This utility model provides an embodiment of a pipe drilling device for bicycle production, including a workbench 1, a drilling assembly mounted on the workbench 1, a clamping frame 21 fixedly connected to the workbench 1, a rotating frame 22 rotatably connected inside the clamping frame 21, a guide rod 23 fixedly connected inside the rotating frame 22, a rotating bracket 24 rotatably connected to the clamping frame 21, a rotating roller 215 rotatably connected inside the rotating bracket 24, a fixing plate 210 fixedly connected to the side of the clamping frame 21 away from the rotating frame 22, a screw 211 threadedly connected inside the fixing plate 210, a pressing block 212 fixedly connected to the bottom of the screw 211, a rubber anti-slip pad 213 fixedly connected to the bottom of the pressing block 212, and a rotating handwheel 214 fixedly connected to the screw 211. The guide rod 23 is located inside the rotating bracket 24, and the rotating frame 22 rotates to drive the rotating bracket 24 to rotate. The screw 211 drives the rubber anti-slip pad 215 fixedly connected to the rotating bracket 24. The pressing block 212 of the sliding pad 213 moves to clamp pipes of different diameters. After the pipe is rotated, the angle of the pipe is adjusted. After the angle is adjusted, the pipe is fixed by the cooperation of the screw 211, the pressing block 212 and the rubber anti-slip pad 213, thus adjusting the angle of the pipe and preventing the pipe from rotating during drilling, thereby improving the accuracy and stability of drilling. The drilling assembly drives the first threaded rod 315 to rotate through the first motor 32, so that the sliding frame 33 moves on the worktable 1 to adjust the horizontal direction of the drill bit 314. The second motor 35 drives the second threaded rod 36 to rotate, so that the sliding block 37 moves on the sliding frame 33 for preliminary vertical adjustment. The third motor 39 drives the third threaded rod 310 to rotate, so that the slider 311 moves on the fixed rod 38 to complete the fine adjustment of the drilling position, improve the drilling accuracy, meet the drilling needs of different positions of bicycle pipes, and improve practicality.
[0025] Please see Figure 2 - Figure 4In this embodiment, the clamping frame 21 has a matching circular groove at the corresponding position of the rotating frame 22. The rotating frame 22 rotates inside the circular groove of the clamping frame 21. The circular groove on the clamping frame 21 matches the rotating frame 22, providing a stable rotation track for the rotating frame 22, making the rotating frame 22 more stable during rotation, reducing shaking, and ensuring the rotation accuracy of the rotating frame 22. This, in turn, ensures more accurate angle adjustment of the connected rotating bracket 24 and the pipe. The rotating frame 22 has a matching through groove at the corresponding position of the rotating bracket 24. The rotating bracket 24 is set inside the through groove of the rotating frame 22. The through groove on the rotating frame 22 provides reasonable installation space for the rotating bracket 24, allowing the rotating bracket 24 to be stably set inside the rotating frame 22. When the rotating frame 22 rotates, the rotating bracket 24 can rotate in coordination, improving practicality. The rotating bracket 24 has a matching through groove at the corresponding position of the smooth rod 23. The smooth rod 23 is set inside the rotating frame 22. Inside the through groove of the movable support 24, the extension and retraction of the hydraulic telescopic rod 26 drives the rotating frame 22 to rotate inside the clamping frame 21, thereby driving the three sets of rotating supports 24 to rotate. This facilitates concentric clamping of pipes of different diameters, improving the practicality of the device. A rotating seat 25 is rotatably connected to the clamping frame 21. A hydraulic telescopic rod 26 is fixedly connected inside the rotating seat 25. A rotating block 29 is fixedly connected to the telescopic end of the hydraulic telescopic rod 26. A fixed ear 27 is fixedly connected to the rotating frame 22. A limit rod 28 is fixedly connected to the side of the fixed ear 27 away from the clamping frame 21. The rotating block 29 is rotatably connected to the limit rod 28. After clamping pipes of different diameters, the angle of the pipe is adjusted by rotating the pipe. After the angle is adjusted, the pipe can be fixed by the cooperation of the screw 211, the pressing block 212 and the rubber anti-slip pad 213, thereby adjusting the angle of the pipe and preventing the pipe from rotating during drilling, thus improving the accuracy and stability of drilling.
[0026] Please see Figure 5 - Figure 6In this embodiment, the drilling assembly includes a fixed frame 31 fixedly connected to the top of the worktable 1, a first motor 32 fixedly connected to the worktable 1, a first threaded rod 315 fixedly connected to the output end of the first motor 32, a sliding frame 33 slidably connected inside the worktable 1, a connecting plate 34 fixedly connected to the inner side of the sliding frame 33, a second motor 35 fixedly connected to the top of the sliding frame 33, a second threaded rod 36 fixedly connected to the output end of the second motor 35, a sliding block 37 slidably connected to the sliding frame 33, a fixed rod 38 fixedly connected to the inner side of the sliding block 37, a third motor 39 fixedly connected to the sliding block 37, and a fixed rod 38 fixedly connected to the third motor. The third threaded rod 310 at the output end of the 39th column, the slider 311 slidably connected to the fixed rod 38, the fourth motor 312 fixedly connected to the top of the slider 311, the rotating rod 313 fixedly connected to the output end of the fourth motor 312, and the drill bit 314 fixedly connected to the bottom of the rotating rod 313, the first threaded rod 315 rotatably connected to the inside of the worktable 1, the sliding frame 33 threadedly connected to the outside of the first threaded rod 315, the second threaded rod 36 rotatably connected to the inside of the sliding frame 33, the sliding block 37 threadedly connected to the outside of the second threaded rod 36, the third threaded rod 310 rotatably connected to the inside of the sliding block 37, and the slider 311 threadedly connected to the third threaded rod 39. Externally, the rotating rod 313 is rotatably connected to the inside of the slider 311. The rotating first threaded rod 315 drives the sliding frame 33 to move, the rotating second threaded rod 36 drives the sliding block 37 to move, and the rotating third threaded rod 310 drives the slider 311 to move. The rotating rod 313 drives the drill bit 314 to rotate. The first motor 32 drives the first threaded rod 315 to rotate, causing the sliding frame 33 to move on the worktable 1, achieving horizontal adjustment of the drill bit 314. The second motor 35 drives the second threaded rod 36 to rotate, allowing the sliding block 37 to move on the sliding frame 33 for initial vertical adjustment. The third motor 39 drives... The third threaded rod 310 rotates, causing the slider 311 to move on the fixed rod 38, completing the fine adjustment of the drilling position, improving the drilling accuracy, meeting the drilling needs of different positions of bicycle tubing, and improving practicality. The fixed frame 31 is provided with scale bars, which are distributed sequentially on the fixed frame 31 and the fixed rod 38. The scale bars on the fixed frame 31 and the fixed rod 38 provide an intuitive reference for adjusting the drilling position. The operator can accurately judge the moving distance of the sliding frame 33 and the slider 311 according to the scale on the scale bar, thereby achieving precise control of the position of the drill bit 314.During the adjustment process, there is no need to rely on experience for estimation, which reduces human error, improves the accuracy of drilling position, and ensures that the drilling quality of bicycle tubes meets production requirements. The sliding frame 33 has a matching through groove at the corresponding position of the sliding block 37. The sliding block 37 slides inside the through groove of the sliding frame 33. The through groove on the sliding frame 33 matches the sliding block 37, providing a stable guiding effect for the movement of the sliding block 37. This ensures that the sliding block 37 can slide smoothly along the direction of the through groove on the sliding frame 33, and avoids the sliding block 37 from deviating or shaking during the movement.
[0027] During operation, the bicycle tubing to be processed is first passed through the clamping frame 21. Then, the hydraulic telescopic rod 26 is extended, and the rotating block 29 at its telescopic end rotates on the limiting rod 28 of the fixing lug 27 on the rotating frame 22. Simultaneously, this pushes the rotating frame 22 to rotate within the circular groove of the clamping frame 21. Since the smooth rod 23 inside the rotating frame 22 passes through the through groove of the rotating bracket 24, the rotation of the rotating frame 22 causes the rotating bracket 24 to rotate synchronously. This facilitates the concentric clamping of bicycle tubing of different diameters, and the rotating roller 21, which is rotatably connected inside the rotating bracket 24... 5. To facilitate the rotation of the bicycle tube after it is clamped, the angle of the bicycle tube can be adjusted. After adjustment, the handwheel 214 on the screw 211 is rotated, causing the screw 211 to be threaded into the fixing plate 210 and move downwards. This moves the pressing block 212 and the rubber anti-slip pad 213 at the bottom downwards simultaneously until the rubber anti-slip pad 213 is firmly pressed against the surface of the tube, fixing and securing the tube to prevent it from sliding freely during subsequent drilling operations and preventing rotation during drilling. This improves the convenience of angle adjustment when drilling bicycle tubes. Then, the operator starts the first motor 32. The output end of the third motor 39 drives the first threaded rod 315 to rotate, causing the sliding frame 33, which is threaded onto the first threaded rod 315, to slide within the worktable 1, thus enabling the drill bit 314 to move horizontally. The operator can precisely control the movement distance of the sliding frame 33 through the scale strip on the fixed frame 31. After the sliding frame 33 is in place, the second motor 35 starts, and its output end drives the second threaded rod 36 to rotate, causing the sliding block 37, which is threaded onto the second threaded rod 36, to slide within the through groove of the sliding frame 33, completing the initial vertical adjustment of the drill bit 314. Then, the third motor 39 starts, and its output end... The third threaded rod 310 is rotated, causing the slider 311, which is threaded onto the third threaded rod 310, to slide on the fixed rod 38 for fine adjustment of the drilling position. The scale bar on the fixed rod 38 can help the operator accurately control the movement distance of the slider 311. Then, the fourth motor 312 is started, and its output end drives the rotating rod 313 to rotate, causing the drill bit 314 at the bottom of the rotating rod 313 to rotate at high speed. During the rotation of the drill bit 314, the second motor 35 is controlled to drive the sliding block 37 to move downward, so that the drill bit 314 gradually approaches and contacts the surface of the pipe, completing the drilling operation.
[0028] Through the above steps, for pipes of different diameters, after clamping, the pipe can be directly rotated to adjust the required drilling angle. Once the angle is determined, the screw 211 is rotated, causing the pressing block 212 and the bottom rubber anti-slip pad 213 to move downwards. The rubber anti-slip pad 213 is used to contact the surface of the pipe to fix the pipe, thereby locking the adjusted angle. In this way, the pipe can be prevented from rotating during drilling, ensuring the accuracy and stability of drilling, and there is no need to repeatedly disassemble and re-clamp the pipe. This simplifies the operation process, improves the convenience of operation, and improves the drilling efficiency of the pipe. This solves the problem that repeated disassembly and re-clamping are required when drilling at multiple angles, which leads to cumbersome operation, low efficiency, and difficulty in ensuring repeatability and positioning accuracy, thus affecting product quality.
