[0002] In the motorcycle manufacturing process, the swingarm is a crucial component, significantly impacting the motorcycle's stability and handling performance. The welding quality of the swingarm directly affects its strength and reliability; therefore, precise clamping and positioning of the swingarm during the welding process is of paramount importance.

[0003] Currently, the clamping and positioning devices used in motorcycle swingarm welding operations have some significant shortcomings. On the one hand, most existing devices have relatively fixed structures and lack flexibility. This makes it difficult for the devices to adapt quickly to different models and specifications of motorcycle swingarms, requiring extensive adjustments or even replacements, which undoubtedly increases production preparation time and costs. For example, for swingarms with special shapes or sizes, traditional devices may not provide suitable support and positioning points, affecting welding accuracy. On the other hand, existing devices also have problems with ease of operation. The complex structure requires operators to spend considerable time and effort on clamping and adjustment, reducing production efficiency. In summary, existing clamping and positioning devices for motorcycle swingarm welding have certain deficiencies in terms of flexibility and ease of operation, failing to adequately meet the needs of motorcycle swingarm welding production. Therefore, this application proposes a clamping and positioning device for motorcycle swingarm welding to solve the above problems. Utility Model Content

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a clamping and positioning device for welding a motorcycle swing arm includes a main support 1. The main support 1 consists of a main support rod 6, a fixed shaft 7, an anti-detachment stop post 8, and a mounting plate 9. The fixed shaft 7 is fixedly installed on the upper end of the main support rod 6, the anti-detachment stop post 8 is fixedly installed on the upper end of the fixed shaft 7, and the mounting plate 9 is fixedly installed on the lower end of the main support rod 6. Several rotating support arms 2 are rotatably mounted on the fixed shaft 7. Each rotating support arm 2 consists of a mounting square post 10, a receiving support tube 11, and fixing bolts 12. The mounting square post 10 is fixedly installed on one end of the receiving support tube 11, and the fixing bolts 12 are fixed to the other end. A telescopic support arm 3 is installed on one side wall of the storage support tube 11. The telescopic support arm 3 consists of a telescopic support plate 13, a connecting plate 14, and an internally threaded sleeve 15. The telescopic support plate 13 is fixedly installed on the inner end of the connecting plate 14, and the internally threaded sleeve 15 is fixedly installed on the outer end of the connecting plate 14. A fixing component 4 is installed on the internally threaded sleeve 15. The fixing component 4 consists of a threaded rod 16, a pressure plate 17, and a handle 18. The pressure plate 17 is rotatably installed on the lower end of the threaded rod 16, and the handle 18 is inserted into the upper part of the threaded rod 16. The support arm 3 is constructed by a main support 1, a rotating... The clamping and positioning device, consisting of the rotating support arm 2, the telescopic support arm 3, and the fixing assembly 4, can flexibly adjust the angle of the rotating support arm 2 according to the shape and size of different models and specifications of motorcycle swing arms. By rotating the rotating support arm 2 on the fixed shaft 7, the angle of each rotating support arm 2 can be adjusted around the fixed shaft 7. Simultaneously, the telescopic support arm 3 can extend and retract within the storage support tube 11. By adjusting the extension length of the telescopic support plate 13 within the storage support tube 11, the overall length of the telescopic support arm 3 is changed, thereby adapting to the fixing requirements of different parts of the motorcycle swing arm and achieving precise positioning. The different positions of the motorcycle swing arm meet the clamping requirements of swing arms of different sizes, effectively solving the problem that the existing device has a fixed structure and is difficult to adapt to different swing arms, greatly reducing the preparation time and cost of motorcycle swing arm production. In addition, the device is easy to operate. The operator can fix or loosen the telescopic support arm 3 by turning the fixing bolt 12, and drive the threaded rod 16 to move up and down in the internal threaded sleeve 15 by turning the handle 18, so that the pressure plate 17 can press or loosen the motorcycle swing arm. The entire clamping and adjustment process is simple and quick, reducing the workload of the operator and improving production efficiency.

[0020] Specifically, the mounting plate 9 on the main support 1 is fixedly mounted on the upper end of the welding workbench 5 by bolts. The mounting column 10 on the rotating support arm 2 has a mounting shaft hole 19 that passes through it vertically. The mounting column 10 is rotatably mounted on the fixing shaft 7 on the main support 1 through the mounting shaft hole 19. Several mounting columns 10 on the rotating support arms 2 are stacked together. A threaded hole 20 is opened on one side wall of the receiving support tube 11, passing through it both inside and outside. Fixing bolts 12 are installed in the threaded hole 20. The telescopic support plate 13 on the telescopic support arm 3 is inserted into the receiving support tube 11 on the rotating support arm 2. The connecting plate 14 is located on the outside of the receiving support tube 11. The threaded rod 16 on the fixing assembly 4 is mounted on the internal threaded sleeve 15 on the telescopic support arm 3. Inside, the pressure plate 17 is located below the internal threaded sleeve 15, and the handle 18 is located above the internal threaded sleeve 15. When several mounting columns 10 on the rotating support arms 2 are stacked together, two adjacent mounting columns 10 are pressed tightly together. At the same time, the length of the fixed shaft 7 matches the height of the stacked mounting columns 10, thereby preventing the rotating support arms 2 from moving longitudinally on the fixed shaft 7. The mounting shaft hole 19 on the mounting column 10 is clearance-fitted with the fixed shaft 7, allowing the mounting column 10 to rotate around the fixed shaft 7, while also preventing the rotating support arms 2 from moving laterally on the fixed shaft 7. After the pressure plate 17 on the fixing assembly 4 presses on the motorcycle swing arm to complete the fixing, due to the reverse force, the rotating support arms 2 and the fixed shaft 7 will abut against each other and be fixed. At this time, the rotating support arms 2 will not easily rotate around the fixed shaft 7 as an axis under the action of external force.

[0021] In use, first, fix the main support 1 to the welding workbench 5 with bolts using the mounting plate 9. Simultaneously, place the motorcycle swing arm on the upper end of the welding workbench 5. Then, according to the shape and size of the motorcycle swing arm, rotate the rotating support arm 2 to adjust its angle around the fixed shaft 7. After determining the angle, loosen the fixing bolt 12, thus disengaging the fixing bolt 12 from the telescopic support plate 13 on the telescopic support arm 3. At this point, the fixation of the telescopic support arm 3 is released. Next, move the telescopic support arm 3, causing the telescopic support plate 13 to extend and retract within the storage support tube 11, thereby adjusting the length of the telescopic support arm 3 to accommodate different parts of the swing arm. To fix the position, after the movable telescopic support arm 3 is adjusted, tighten the fixing bolt 12 so that the fixing bolt 12 abuts against the fixed telescopic support plate 13, thereby fixing the position of the movable telescopic support arm 3. Finally, move the motorcycle swing arm to the corresponding position, and then turn the handle 18 to drive the threaded rod 16 to move downward in the internal threaded sleeve 15, so that the pressure plate 17 presses the motorcycle swing arm, thereby completing the fixing of the motorcycle swing arm. After the motorcycle swing arm is welded, the handle 18 can be turned in the opposite direction, so that the threaded rod 16 moves upward in the internal threaded sleeve 15, thereby causing the pressure plate 17 to disengage from the motorcycle swing arm, and finally the motorcycle swing arm can be removed.

[0022] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
