Technical Field

[0001] This utility model relates to the field of bicycle manufacturing technology, specifically a bicycle frame processing device. Background Technology

[0002] Bicycles are typically small, two-wheeled land vehicles. Riders power themselves by pedaling, making them a green and environmentally friendly mode of transportation. Bicycles can replace walking, are environmentally friendly, and do not pollute the environment, aligning with modern low-carbon and environmentally friendly concepts. They also provide exercise, making them an ideal mode of transportation with multiple benefits. The frame is the skeleton of the bicycle, bearing the greatest weight of the rider and cargo. After welding, bicycle frame components require localized fine polishing and painting.

[0003] According to the authorized announcement number CN210099749U, an improved bicycle frame processing device is disclosed. The processing device is set below the bicycle frame. The bicycle frame is composed of a connecting tube, a triangle I welded to one side of the connecting tube, and two triangles II welded to the other side of the connecting tube. The triangle I is located on the bisecting plane of the included angle between the two triangles II.

[0004] In the process of developing this utility model, the inventors discovered that at least the following problems remain unresolved in the prior art: the aforementioned example uses support mechanism I and support mechanism II to adjust their positions using sliders, thereby providing limiting support for the vehicle frame. However, during use, it is inconvenient to adjust the processing angle of the vehicle frame, and the use of multiple support mechanisms makes operation cumbersome and results in limited stability.

[0005] Therefore, we propose a bicycle frame processing device that can solve the above problems. Utility Model Content

Detailed Implementation

[0020] Please see Figs. 1-3 This utility model provides a technical solution: a bicycle frame processing device, including a processing table 1 and a frame support tube 25. A limiting post 11 is vertically and rotatably connected to the middle of the upper surface of the processing table 1. The upper end of the limiting post 11 is inserted into the frame support tube 25. It also includes a fixing mechanism for driving inner support bars 13 to fix the frame support tube 25. The fixing mechanism includes four sets of inner support bars 13 pressed against the inner wall of the frame support tube 25 and an air pump 15. The four sets of inner support bars 13 are vertically and equidistantly distributed on the outside of the limiting post 11. An air guide groove 2 is vertically formed inside the limiting post 11, and piston grooves 21 are equidistantly formed on the outside of the air guide groove 2. A piston 22 is slidably connected inside the piston groove 21. A fixing rod 23 is horizontally fixed on the side of the piston 22 away from the air guide groove 2. One end of the fixing rod 23 is fixedly connected to the outside of the inner support bar 13. A connecting groove 14 is opened inside the lower end of the processing table 1. The limiting post 11 is rotatably connected to the inner wall of the top of the connecting groove 14 through a sealed bearing. The bottom end of the air guide groove 2 is connected to the connecting groove 14. The air outlet pipe 16 of the air pump 15 is connected to the connecting groove 14. The limiting post 11 vertically penetrates the middle of the limiting plate 12 and is fixedly connected to the limiting plate 12. The limiting plate 12 is horizontally placed on the upper surface of the processing table 1.

[0021] In this technical solution, the upper end of the limiting post 11 is vertically inserted into the frame support tube 25 to be processed. The limiting post 11 is supported by the horizontal limiting plate 12 on the outside. The air pump 15 is controlled by the corresponding controller to work and inflate the connecting groove 14 through the air outlet pipe 16. Then, the air is inflated into the piston groove 21 through the air guide groove 2 inside the limiting post 11. As the air pressure in the piston groove 21 increases, the piston 22 in the piston groove 21 can be pushed away from the air guide groove 2. The fixing rod 23 can push the four sets of inner support bars 13 on the outside of the limiting post 11 away from the limiting post 11 and press against the inner wall of the frame support tube 25, thereby limiting and fixing the frame. It should be noted that there is a sealing ring on the outside of the piston 22, which can improve the sealing performance of the connection between the piston 22 and the piston groove 21.

[0022] In this embodiment, a rotating mechanism is used to drive the frame support tube 25 to rotate. The rotating mechanism includes a drive motor 32 for driving the frame support tube 25 to rotate. An installation groove 3 is provided above the connecting groove 14. The lower end of the limiting post 11 vertically passes through the middle of the large gear 31 and is fixedly connected to the large gear 31. A small gear 33 is fixedly installed on the shaft end of the drive motor 32. The small gear 33 meshes with the large gear 31. The drive motor 32 is fixedly connected to one side of the inner wall at the bottom of the installation groove 3.

[0023] In this technical solution, the drive motor 32 is controlled by the corresponding controller to drive the small gear 33 to rotate in the mounting groove 3. The large gear 31 drives the limit post 11 to rotate, thereby driving the frame support tube 25 fixedly connected to the upper end of the limit post 11 to rotate, which facilitates the adjustment of the frame processing angle.

[0024] In this embodiment, an exhaust pipe 17 is installed through the inner wall of the connecting groove 14 on the side away from the exhaust pipe 16. An electromagnetic valve 18 is installed inside the exhaust pipe 17. A spring 24 is installed on the side of the piston 22 away from the air guide groove 2. The spring 24 is sleeved on the outside of the fixing rod 23.

[0025] In this technical solution, after the frame is processed, the control solenoid valve 18 is opened, and the compressed air in the piston groove 21 can be discharged through the exhaust pipe 17. Through the elastic force of the spring 24 on the side of the piston 22 away from the air guide groove 2, the piston 22 can be pushed closer to the air guide groove 2. Through the fixing rod 23, the four sets of inner support bars 13 can be pulled closer to the limiting post 11 and separated from the inner wall of the frame support tube 25, thereby releasing the limiting fixation of the frame support tube 25, and the processed frame can be removed.

[0026] When using a bicycle frame processing device, the upper end of the limiting post 11 is vertically inserted into the frame support tube 25 to be processed. The horizontal limiting plate 12 on the outside of the limiting post 11 can limit and support the frame. The corresponding controller controls the air pump 15 to work, and air is injected into the piston groove 21 through the air outlet pipe 16, the connecting groove 14 and the air guide groove 2. As the air pressure in the piston groove 21 increases, it can push the piston 22 in the piston groove 21 away from the air guide groove 2. The fixing rod 23 can push the four sets of inner support bars 13 on the outside of the limiting post 11 away from the limiting post 11 and press them against the inner wall of the frame support tube 25, thereby limiting and fixing the frame. The control drive motor 32 is activated, which drives the pinion 33 to rotate. The pinion 33, via the large gear 31, drives the limit post 11 to rotate, thereby causing the frame support tube 25, which is fixedly connected to the upper end of the limit post 11, to rotate. This facilitates the adjustment of the frame's machining angle. After the frame is machined, the control solenoid valve 18 is opened, allowing compressed air to be discharged from the piston groove 21 via the exhaust pipe 17. The spring force of the spring 24 on the side of the piston 22 away from the air guide groove 2 pushes the piston 22 closer to the air guide groove 2. The fixing rod 23 pulls the four sets of inner support bars 13 closer to the limit post 11 and separates them from the inner wall of the frame support tube 25, thereby releasing the limiting fixation of the frame support tube 25.
