Description

Technical Field

[0001] This utility model belongs to the field of mechanical welding technology, specifically relating to a welding fixture for motorcycle parts. Background Technology

[0002] The motorcycle frame is an important safety component of a motorcycle. It has the functions of bearing weight, protecting against impacts, and supporting and fixing most of the motorcycle's accessories. Therefore, motorcycle frames have high requirements for rigidity and strength to ensure the safety and stability of the motorcycle.

[0003] Most of the welding equipment currently available on the market for assembling and splicing motorcycle frames is a fixed structure. When the model of the motorcycle frame to be welded is different, the fixture needs to be changed. The fixture and its components can be operated by the welding equipment through the connection between the fixture and the welding platform.

[0004] By adjusting the welding platform at multiple angles and coordinating with the welding robot, the weldable parts and their quality can be guaranteed.

[0005] Chinese patent document with application number CN202411464885.0 discloses a rotary positioner auxiliary welding system and its auxiliary welding method, including a transfer device, a welding device, and an auxiliary device that can fix the chassis suspension. The auxiliary device includes a main frame that can rotate around a vertical axis, and side supports that are arranged opposite to each other on both sides of the main frame and can rotate around a horizontal axis. The clamping and welding of the scissor chassis can be performed simultaneously.

[0006] Further research by the applicant revealed that due to structural issues, the platform for adjusting the angle of the workpiece and fixture in the technical solution was not stable enough, making the placement plate for placing the fixture and parts unstable. The placement plate was prone to shaking or even shifting during the driving and flipping process, which was not conducive to the coordination between welding robots and affected the quality of component welding.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A welding fixture for motorcycle parts, comprising:

[0009] A transposition table, the transposition table including a transposition frame and several sets of secondary longitudinal frames connected to the inner side of the transposition frame and distributed along the length direction of the transposition table;

[0010] A rotating mechanism is symmetrically arranged on both sides of the switching platform. The rotating mechanism has a rotating disk, and a main cross frame is connected between the two rotating disks.

[0011] A limiting mechanism, cooperating with the secondary longitudinal frame, the limiting mechanism being symmetrically distributed on both sides of the main transverse frame and arranged along the length direction of the main transverse frame; and

[0012] The pressing mechanism is symmetrically distributed on both sides of the transposition frame and connected to the main cross frame. The pressing mechanism has a pressing block that acts on the upper surface of the transposition platform.

[0013] Furthermore, the limiting mechanism includes a limiting arm with one end connected to the side of the main crossbeam and the other end extending outward from the main crossbeam, and a limiting block acting on the bottom of the secondary longitudinal frame is connected to the top of the limiting arm.

[0014] Furthermore, the cross-section of the limiting block is U-shaped.

[0015] Furthermore, a rubber pad is provided on the contact surface between the limiting block and the secondary longitudinal frame.

[0016] Furthermore, the pressing mechanism also includes a drive source and a linkage structure, and the pressing block is connected to the drive source through the linkage structure.

[0017] Furthermore, each side has two sets of pressing mechanisms, which are connected to the main crossbeam via pressing frames.

[0018] Furthermore, the transposition platform also includes a transposition plate connected to the transposition frame, and the transposition plate has a plurality of mounting holes.

[0019] Furthermore, the rotating mechanism includes a support frame and a power source.

[0033] like Figure 1 - Figure 6As shown, a welding fixture for motorcycle parts according to this utility model includes a shifting table 1, a rotating mechanism 2, a limiting mechanism 3, and a pressing mechanism 4.

[0034] The transposition table 1 includes a transposition frame 10 and several sets of secondary longitudinal frames 11 connected to the inner side of the transposition frame 10 and distributed along the length of the transposition table 1.

[0035] The rotating mechanism 2 is symmetrically arranged on both sides of the transposition table 1. The rotating mechanism 2 has a rotating disk 20, and a main cross frame 21 is connected between the two rotating disks 20.

[0036] The rotating mechanism 2 includes a support frame 22 and a power source 23. The support frame 22 provides support for the upper components, and the power source 23 is a motor, with its rotating disk 20 connected to the output end of the motor. This motor is not merely a motor; it also includes a corresponding gearbox transmission structure.

[0037] The limiting mechanism 3 cooperates with the secondary longitudinal frame 11. The limiting mechanism 3 is symmetrically distributed on both sides of the main transverse frame 21 and is arranged along the length of the main transverse frame 21. This arrangement makes the connection between the pressing mechanism 4 and the secondary longitudinal frame and the transposition frame more stable.

[0038] The pressing mechanism 4 is symmetrically distributed on both sides of the transposition frame 10 and connected to the main cross frame 21. The pressing mechanism 4 has a pressing block 40 that acts on the upper surface of the transposition table 1.

[0039] By using a limiting mechanism 3 and a pressing mechanism 4, the sides of the secondary longitudinal frame 11 and the shifting frame 10 are fixed respectively, so that the entire shifting platform 1 can rotate stably under the action of the rotating mechanism 2. This allows the fixtures and components connected to the upper part of the shifting platform 1 to move along a predetermined control path / angle, resulting in higher quality cooperation with the welding robot 5 and improved welding quality of the workpiece.

[0040] like Figure 5 , Figure 6 As shown, the limiting mechanism 3 includes a limiting arm 30 with one end connected to the side of the main crossbeam 21 and the other end extending outward from the main crossbeam 21. A limiting block 31 acting on the bottom of the secondary longitudinal frame 11 is connected to the top of the limiting arm 30.

[0041] It should be noted that the limiting block 31 has a concave cross-section. This design ensures that the secondary longitudinal frame is securely connected within the notch in the limiting block 31, preventing wobbling.

[0042] A rubber pad (not shown in the figure) is provided on the contact surface between the limiting block 31 and the secondary longitudinal frame 11. The rubber pad is provided to avoid scratches that may be caused by hard contact between the secondary longitudinal frame 11 and the limiting block 31, and at the same time increase the friction between the two.

[0043] The pressing mechanism 4 also includes a drive source 41 and a connecting rod structure 42. The pressing block 40 is connected to the drive source 41 through the connecting rod structure 42.

[0044] It should be noted that the structure of the linkage structure 42 will vary depending on the drive source 41. The drive source 41 can be a motor, a screw mechanism, or other structures with telescopic functions, such as a cylinder. There are no specific restrictions, as long as it can drive the lower pressure block 40 to move closer to or further away from the upper end of the shift frame 10.

[0045] This fixture allows for angle adjustment of the workpiece's position to ensure precision and efficiency in the welding process. By rotating the workpiece, the welding robot's welding head can easily reach various welding points, making it particularly suitable for welding complex shapes or large workpieces. Precise positioning and stable movement reduce welding defects.

[0046] To further increase the stability of the pressing mechanism 4 on the transposition table 1, there are two sets of pressing mechanisms 4 on each side. The pressing mechanism 4 is connected to the main cross frame 21 through the pressing frame 43.

[0047] The transposition table 1 in this embodiment also includes a transposition plate 12 connected to the transposition frame 10, and the transposition plate 12 has a plurality of mounting holes 120. The mounting holes 120 are threaded holes, and the fixtures can be connected and installed through the mounting holes 120.

[0048] This fixture should also include a control system for the equipment's movement, typically a PLC or CNC system. The control system includes drive devices such as servo motors, and may also include devices such as speed reducers, couplings, bearing assemblies, and sensor components. Multiple drive devices can be connected to different structures to be driven.

[0049] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
