Description

Technical Field

[0001] This utility model relates to the field of bicycle tube drilling technology, specifically a multi-hole precision drilling device for bicycle tube processing. Background Technology

[0002] A bicycle, also known as a pedal bike or cyclist, is typically a small, two-wheeled land vehicle. Riders power it by pedaling, making it a green and environmentally friendly mode of transportation. In the bicycle manufacturing industry, tubing, as a core component of the frame, directly affects the frame assembly precision and overall structural strength through its drilling and machining accuracy.

[0003] A bicycle tube drilling device, disclosed in CN207655953U, comprises an electric push rod, a G-clamp, a moving block, a rack, a gear, a drive motor, and a drill bit. The bicycle tube is clamped by the G-clamp, and the moving block is rotated by the meshing of the rack and gear, so that the drill bit is aligned with the position to be drilled on the bicycle tube. The electric push rod drives the clamped bicycle tube to descend and be drilled by the drill bit.

[0004] The bicycle tube drilling device uses a G-clamp to hold and fix the bicycle tube. However, the G-clamp requires frequent adjustment of the pressure head position to fit the curved surface of the tube, and different diameter tubes require different sized pressure heads, which affects work efficiency. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a multi-hole precision drilling device for processing bicycle tubing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-hole precision drilling device for processing bicycle tubing, comprising a drilling frame, a lifting mechanism arranged around the drilling frame, a clamping mechanism arranged on the front of the lifting mechanism, a bicycle tubing body arranged inside the clamping mechanism, a hydraulic cylinder fixedly connected to the top of the inner side of the drilling frame, a lifting frame fixedly connected to the bottom of the hydraulic cylinder, a servo motor fixedly connected to the inner side of the lifting frame, a drill rod fixedly connected to the bottom of the servo motor, and a limit rod fixedly connected to the back of the top of the lifting frame, the limit rod being slidably connected to the inner side of the drilling frame; The clamping mechanism includes a load-bearing plate disposed on the front of the lifting mechanism. A protective frame is fixedly connected to the bottom of the load-bearing plate. A bidirectional threaded rod is rotatably connected to the inner side of the protective frame. A rotating disk is fixedly connected to the front of the bidirectional threaded rod. A threaded plate is threadedly connected to the outer side of the bidirectional threaded rod. A linkage plate is fixedly connected to the top of the threaded plate. A movable plate is fixedly connected to the top of the linkage plate. A V-shaped clamping plate is fixedly connected to the inner side of the movable plate. A slider is fixedly connected to the inner side of the linkage plate.

[0007] Preferably, the inner side of the protective frame is provided with a groove corresponding to the movement trajectory of the threaded plate, and the threaded plate is slidably connected inside the groove. Through the groove, the threaded plate can slide inside the protective frame.

[0008] Preferably, the inner side of the load-bearing plate is provided with a moving groove corresponding to the movement trajectory of the slider, and the slider is slidably connected inside the moving groove. Through the moving groove, the slider can slide inside the load-bearing plate, and the slider can limit the linkage plate.

[0009] Preferably, the V-shaped clamp is disposed on the periphery of the bicycle tube body, and the inner side of the V-shaped clamp is in close contact with the periphery of the bicycle tube body. The V-shaped clamp can clamp and fix bicycle tube bodies of different sizes, making the bicycle tube body more stable when drilling.

[0010] Preferably, the lifting mechanism includes a fixed frame, which is fixedly connected to the middle of the outer periphery of the drilling frame. A one-way threaded rod is rotatably connected to the inner side of the fixed frame. A rotating disk is fixedly connected to the top of the one-way threaded rod. A threaded block is threadedly connected to the outer periphery of the one-way threaded rod. The threaded block is slidably connected to the inner side of the fixed frame. A linkage rod is fixedly connected to the front of the threaded block.

[0011] Preferably, the inner side of the threaded block has a circular hole corresponding to the position of the drilling frame, and the threaded block is slidably connected to the inner side of the circular hole. Through the circular hole, the threaded block can slide around the drilling frame, making the threaded block more stable during the lifting and lowering process.

[0012] Preferably, the protective frame has a fixing groove on the front corresponding to the position of the linkage rod. The linkage rod is slidably connected inside the fixing groove and fixedly connected to the back end of the load-bearing plate. Through the fixing groove, when the threaded block moves, it can drive the linkage rod to move up and down.

[0013] Compared with the prior art, this utility model provides a multi-hole precision drilling device for processing bicycle tubing, which has the following advantages: This multi-position precision drilling device for bicycle tubing processing uses a clamping mechanism driven by a bidirectional threaded rod to bring the threaded plates and linkage plates on both sides closer together. This allows the V-shaped clamping plate to fit tightly against the outer periphery of the bicycle tubing, adapting to the clamping requirements of tubing of different diameters. The device is equipped with a protective frame slide groove for guiding the threaded plate and a load-bearing plate movement groove for guiding the slider, preventing tubing from shifting during clamping. This provides a stable foundation for subsequent precision drilling and reduces hole diameter deviation or hole position shift caused by tubing swaying.

[0014] This multi-position precision drilling device for bicycle tubing processing utilizes a lifting mechanism that employs a one-way threaded rod and a threaded block for threaded engagement. A rotating disc drives the threaded block and linkage rod to stably raise and lower the load-bearing plate, easily adjusting the relative height between the tubing and the drill rod. Simultaneously, a hydraulic cylinder drives the lifting frame and drill rod to rise and fall vertically. A limit rod guides the lifting frame, ensuring the drill rod drills vertically. This combination enables multi-position processing of tubing at different heights and positions, eliminating the need for frequent disassembly and reassembly of the tubing and improving processing efficiency.

A protective frame 27 is fixedly connected to the bottom of the load-bearing plate 29. A bidirectional threaded rod 25 is rotatably connected to the inner side of the protective frame 27. A rotating disk 28 is fixedly connected to the front of the bidirectional threaded rod 25. A threaded plate 26 is threadedly connected to the outer side of the bidirectional threaded rod 25. A linkage plate 24 is fixedly connected to the top of the threaded plate 26. A movable plate 22 is fixedly connected to the top of the linkage plate 24. A V-shaped clamping plate 21 is fixedly connected to the inner side of the movable plate 22. A slider 23 is fixedly connected to the inner side of the linkage plate 24.

[0021] Furthermore, a groove corresponding to the movement trajectory of the threaded plate 26 is provided on the inner side of the protective frame 27, and the threaded plate 26 is slidably connected inside the groove. Through the groove, the threaded plate 26 can slide inside the protective frame 27.

[0022] Furthermore, a moving groove corresponding to the movement trajectory of the slider 23 is provided on the inner side of the load-bearing plate 29, and the slider 23 is slidably connected inside the moving groove. Through the moving groove, the slider 23 can slide inside the load-bearing plate 29, and the slider 23 can limit the linkage plate 24.

[0023] Furthermore, a V-shaped clamp 21 is provided on the periphery of the bicycle tube body 1, and the inner side of the V-shaped clamp 21 is in close contact with the periphery of the bicycle tube body 1. The V-shaped clamp 21 can clamp and fix bicycle tube bodies 1 of different sizes, making the bicycle tube body 1 more stable when drilling. Example 2

[0024] Please see Figure 1-4 Furthermore, based on Embodiment 1, the lifting mechanism 7 further includes a fixed frame 74, which is fixedly connected to the middle of the outer periphery of the drilling frame 5. A one-way threaded rod 72 is rotatably connected to the inner side of the fixed frame 74. A rotating disk 71 is fixedly connected to the top of the one-way threaded rod 72. A threaded block 73 is threadedly connected to the outer periphery of the one-way threaded rod 72. The threaded block 73 is slidably connected to the inner side of the fixed frame 74. A linkage rod 75 is fixedly connected to the front of the threaded block 73.

[0025] Furthermore, the inner side of the threaded block 73 is provided with a circular hole corresponding to the position of the drilling frame 5, and the threaded block 73 is slidably connected to the inner side of the circular hole. Through the circular hole, the threaded block 73 can slide on the outer side of the drilling frame 5, making the threaded block 73 more stable during the lifting and lowering process.

[0026] Furthermore, the protective frame 27 has a fixing groove on the front corresponding to the position of the linkage rod 75. The linkage rod 75 is slidably connected inside the fixing groove and is fixedly connected to the back end of the load-bearing plate 29. Through the fixing groove, when the threaded block 73 moves, it can drive the linkage rod 75 to move up and down.

[0027] In actual operation, when this device is used, when it is necessary to drill holes in the bicycle tube body 1, the bicycle tube body 1 is placed on top of the load-bearing plate 29, and the operator manually rotates the rotating disk 28, so that the rotating disk 28 drives the bidirectional threaded rod 25 to rotate, so that the bidirectional threaded rod 25 drives the threaded plate 26 and the linkage plate 24 to move, so that the linkage plate 24 drives the V-shaped clamping plate 21 to move through the moving plate 22, so that the V-shaped clamping plate 21 can clamp and fix the bicycle tube body 1. After clamping the bicycle tube body 1, the operator rotates the rotary disk 71, causing the rotary disk 71 to drive the one-way threaded rod 72 to rotate. The one-way threaded rod 72 drives the threaded block 73 and the linkage rod 75 to move upward, allowing the linkage rod 75 to drive the load-bearing plate 29 to move upward. The load-bearing plate 29 can then drive the clamped bicycle tube body 1 to rise and fall, bringing the bicycle tube body 1 closer to the drill rod 3. The operator then turns on the servo motor 6 switch and the hydraulic cylinder 8 switch, causing the hydraulic cylinder 8 to push the lifting frame 4 and the servo motor 6 downward. This causes the three servo motors 6 to drive the three drill rods 3 downward, allowing the three drill rods 3 to drill holes in the top of the bicycle tube body 1. Because the bicycle tube body 1 is clamped by the V-shaped clamp 21, its position is less likely to shift during drilling, making the drilling position more precise.
