Description

Technical Field

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

[0002] The bicycle frame is the core load-bearing component. Bicycle frames are mostly made of lightweight materials such as aluminum alloy and carbon fiber. During the transition between various processes, the frame needs to be frequently rotated at multiple angles to ensure convenient operation on all processing surfaces. Therefore, the frame rotation device has become a key auxiliary equipment on the bicycle production line.

[0003] Traditional clamping methods often employ single-point clamping, lacking effective anti-slip design. During the flipping process, the frame is prone to slippage and displacement due to vibration or uneven clamping force, affecting processing accuracy and posing safety hazards. Therefore, to address these issues, improve frame production efficiency and quality, and reduce waste, this utility model was developed. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a vehicle frame assembly tilting device, comprising: a support structure and a tilting motor. The tilting motor is fixedly connected to the outer wall of the support structure. A clamping structure is fixedly connected to the rotating shaft of the tilting motor. The clamping structure includes a stabilizer frame. The outer wall of the stabilizer frame is fixedly connected to the rotating shaft of the tilting motor. A drive motor is fixedly connected to the outer wall of the stabilizer frame. A gear is fixedly connected to the output shaft of the drive motor. A rack is symmetrically meshed on the outer wall of the gear. A clamping block is fixedly connected to the outer wall of the rack. An anti-slip strip is fixedly connected to the outer wall of the clamping block.

[0005] Preferably, the clamping block adopts an L-shaped structure, the inner wall of the rack is slidably connected to the outer wall of the stabilizer, the outer wall of the gear is rotatably connected to the inner wall of the stabilizer, and the anti-slip strip is made of rubber.

[0006] Preferably, the support structure includes a base, which is fixed to the ground by bolts. A bidirectional lead screw is rotatably connected to the inner wall of the base, a handle is fixedly connected to the outer wall of the bidirectional lead screw, and sliders are symmetrically threaded to the outer wall of the bidirectional lead screw.

[0007] Preferably, a support frame is rotatably connected to the top of the slider, and a fixed structure is rotatably connected to the end of the support frame away from the slider.

[0008] Preferably, the fixing structure includes a fixing plate, the outer wall of which is slidably connected to the inner wall of the base.

[0009] Preferably, a support plate is fixedly connected to the top of the fixing plate, and a reinforcing plate is fixedly connected between the fixing plate and the support plate.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model features a clamping structure with symmetrical gear and rack transmission. When the drive motor rotates the gears, the racks on both sides slide synchronously, allowing for flexible adjustment of the clamping block spacing according to the frame width. Combined with the enveloping design of the L-shaped clamping blocks, it can stably clamp bicycle frames of different diameters and shapes. The rubber anti-slip strips on the outer wall of the clamping blocks directly adhere to the frame surface, increasing frictional resistance and effectively solving the problem of frame slippage and displacement caused by vibration or uneven clamping force during the flipping process.

[0011] 2. This utility model, by setting up a support structure, allows the slider to move synchronously closer or further away by rotating the handle, thereby adjusting the height and support position of the fixed structure. It is suitable for bicycle frames of different sizes and heights. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0015] Example: Please see Figure 1 - Figure 2This utility model provides a technical solution: a frame assembly flipping device, including: a support structure 1 and a flipping motor 2. The outer wall of the support structure 1 is fixedly connected to the flipping motor 2. The rotating shaft of the flipping motor 2 is fixedly connected to a clamping structure 3. The clamping structure 3 includes a stabilizer 31. The outer wall of the stabilizer 31 is fixedly connected to the rotating shaft of the flipping motor 2. The outer wall of the stabilizer 31 is fixedly connected to a drive motor 32. The output shaft of the drive motor 32 is fixedly connected to a gear 33. The outer wall of the gear 33 is symmetrically meshed with a rack 34. The outer wall of the rack 34 is fixedly connected to a clamping block 35. The outer wall of the clamping block 35 is fixedly connected to an anti-slip strip 36. The clamping block 35 adopts an L-shaped structure. The inner wall of the rack 34 is slidably connected to the outer wall of the stabilizer 31. The outer wall of the gear 33 is rotatably connected to the inner wall of the stabilizer 31. The anti-slip strip 36 is made of rubber. First, the frame assembly to be flipped is placed in the support area inside the stabilizer 31 to ensure that the frame is in contact with the reference surface of the stabilizer 31. The drive motor 32 in the clamping structure 3 is activated. The output shaft of the drive motor 32 drives the gear 33 to rotate. Because the gear 33 meshes symmetrically with the rack 34, the rotation of the gear 33 synchronously drives the racks 34 on both sides to slide along the outer wall of the stabilizer 31. During the movement of the racks 34, the clamping blocks 35 fixed to them move closer to the frame. Since the clamping blocks 35 adopt an L-shaped structure, they can form a wrap-around clamping from the side of the frame. At the same time, the anti-slip strips 36 on the outer wall of the clamping blocks 35 will tightly adhere to the surface of the frame, increasing frictional resistance and preventing slippage. After the clamping blocks 35 clamp the frame, the tilting motor 2 is activated. The rotating shaft of the tilting motor 2 drives the entire clamping structure 3 to rotate, realizing the tilting operation of the frame assembly.

[0016] Please see Figure 3 The support structure 1 includes a base 11, which is fixed to the ground by bolts. A double-acting lead screw 12 is rotatably connected to the inner wall of the base 11, and a handle 13 is fixedly connected to the outer wall of the double-acting lead screw 12. A slider 14 is symmetrically threaded to the outer wall of the double-acting lead screw 12, and a support frame 15 is rotatably connected to the top of the slider 14. A fixing structure 16 is rotatably connected to the end of the support frame 15 away from the slider 14. First, the base 11 is fixed to the designated position on the ground by bolts to ensure the overall stability of the support structure 1. According to the size and height requirements of the frame to be tilted, the handle 13 on the outer wall of the double-acting lead screw 12 is rotated, and the handle 13 drives the double-acting lead screw 12 to rotate on the inner wall of the base 11. Because the double-acting lead screw 12 and the slider 14 are symmetrically threaded, when the double-acting lead screw 12 rotates, it drives the sliders 14 on both sides to move synchronously closer or further away from the inner wall of the base 11. During the movement of slider 14, the support frame 15 connected to the top rotates and changes angle. The end of support frame 15 away from slider 14 pushes the fixing structure 16 to slide along the inner wall of base 11, thereby adjusting the height of fixing structure 16 so that fixing structure 16 can accurately adapt to the support requirements of the frame and provide stable support for subsequent flipping.

[0017] Please see Figure 4 The fixing structure 16 includes a fixing plate 161, the outer wall of which is slidably connected to the inner wall of the base 11. A support plate 162 is fixedly connected to the top of the fixing plate 161, and a reinforcing plate 163 is fixedly connected between the fixing plate 161 and the support plate 162. When the support frame 15 in the support structure 1 is adjusted to the target position, the fixing plate 161 will slide along the inner wall of the base 11 to a support point that matches the frame under the push of the support frame 15. At this time, the support plate 162 on the top of the fixing plate 161 provides support for the frame. Since the reinforcing plate 163 is fixedly connected between the fixing plate 161 and the support plate 162, the reinforcing plate 163 can effectively distribute the frame weight borne by the support plate 162, preventing the fixing plate 161 and the support plate 162 from deforming due to concentrated force.

[0018] Working principle: In use, the base 11 is first fixed to the designated position on the ground with bolts to ensure the overall stability of the support structure 1. Based on the size and height requirements of the frame to be flipped, the handle 13 on the outer wall of the bidirectional lead screw 12 is rotated, causing the bidirectional lead screw 12 to rotate on the inner wall of the base 11. Because the bidirectional lead screw 12 and the slider 14 are symmetrically threaded, the rotation of the bidirectional lead screw 12 drives the sliders 14 on both sides to move synchronously closer to or further away from the inner wall of the base 11. During the movement of the sliders 14, the angle of the top-rotating support frame 15 changes. The end of the support frame 15 away from the slider 14 pushes the fixing structure 16 to slide along the inner wall of the base 11, thereby adjusting the height of the fixing structure 16 so that it can accurately adapt to the support requirements of the frame, providing stable support for subsequent flipping. The frame assembly to be flipped is first placed in the support area inside the stabilizer 31, ensuring that the frame is in contact with the reference surface of the stabilizer 31. The drive motor 32 in the clamping structure 3 is activated. The output shaft of the drive motor 32 drives the gear 33 to rotate. Because the gear 33 and the rack 34 are symmetrically meshed, the rotation of the gear 33 will synchronously drive the racks 34 on both sides to slide along the outer wall of the stabilizer 31. During the movement of the racks 34, the clamping blocks 35 fixed to them will move closer to the frame. Since the clamping blocks 35 adopt an L-shaped structure, they can form a wrap-around clamping from the side of the frame. At the same time, the anti-slip strips 36 on the outer wall of the clamping blocks 35 will closely adhere to the surface of the frame, increasing the frictional resistance and preventing slippage. After the clamping blocks 35 clamp the frame, the tilting motor 2 is activated. The rotating shaft of the tilting motor 2 drives the entire clamping structure 3 to rotate, realizing the tilting operation of the frame assembly. When the support frame 15 in the support structure 1 is adjusted to the target position, the fixing plate 161 will slide along the inner wall of the base 11 to the support point that matches the frame under the push of the support frame 15. At this time, the support plate 162 on the top of the fixed plate 161 provides support for the frame. Since the fixed plate 161 and the support plate 162 are fixedly connected by the reinforcing plate 163, the reinforcing plate 163 can effectively distribute the frame weight borne by the support plate 162 and prevent the fixed plate 161 and the support plate 162 from deforming due to concentrated force.
