The fork bottom fixing seat has a third groove for the bottom end of the left body and the bottom end of the right body to be embedded. The output ends of the two fork top clamping cylinders can respectively clamp the top end of the left body and the top end of the right body. The left side of the fork left fixing seat and the right side of the fork right fixing seat are both provided with push cylinders, which can bring the fork left fixing seat and the fork right fixing seat closer to each other.

[0005] The present invention is further configured such that: a flat fork connecting block abutment and a flat fork connecting block clamping cylinder are provided between the left flat fork body fixing seat and the right flat fork body fixing seat. In use, one side of the flat fork connecting block is pressed by the output end of the flat fork connecting block clamping cylinder, and the other side abuts against the flat fork connecting block abutment.

[0006] The present invention is further configured such that magnetic blocks are provided in the first groove and the second groove.

[0007] The present invention is further configured such that the push cylinder is a pneumatic cylinder.

[0008] In summary, this utility model has the following beneficial effects:

[0009] This invention achieves precise positioning of the left and right sides of the flat fork and the connecting block through groove fitting, magnetic block adsorption, and clamping cylinder fixation, reducing manual adjustment time. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.

[0011] In the diagram: 1. Base plate; 2. Left side mounting bracket for the flat fork; 3. Right side mounting bracket for the flat fork; 4. Bottom mounting bracket for the flat fork; 5. Top clamping cylinder for the flat fork; 6. Push cylinder; 7. Connecting block stop for the flat fork; 8. Clamping cylinder for the flat fork connecting block; 9. Third groove. Detailed Implementation

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] Example: A welding fixture for a motorcycle swingarm, such as... Figure 1 As shown, the left and right body fixing seats of the flat fork are symmetrically arranged on both sides of the base plate 1 and are slidably connected to the base plate 1 via slide rails, allowing them to move laterally along the base plate 1 to accommodate flat forks of different sizes. The left body fixing seat 2 has a first groove that matches the surface of the left body of the flat fork, and the right body fixing seat 3 has a second groove that matches the surface of the right body of the flat fork. The groove shapes fit the outline of the flat fork to enhance positioning stability. The bottom fixing seat 4 of the flat fork is located in the middle of the base plate 1, and its third groove 9 is used to embed into the bottom ends of the left and right bodies of the flat fork to ensure that the bottom ends of the two are aligned. Two clamping cylinders are provided, located above the top ends of the left and right bodies of the flat fork, respectively, and press down to fix the top ends of the flat fork through the output end to prevent displacement during welding.

[0014] A push cylinder 6 (preferably a pneumatic cylinder) is provided on the left side of the left body fixing seat 2 and the right side of the right body fixing seat 3 of the flat fork. The push cylinder 6 drives the left and right fixing seats to move towards the middle, so that the left and right bodies of the flat fork fit tightly against the flat fork connecting block, ensuring symmetry and uniform welding gap.

[0015] When in use, the left side of the flat fork is inserted into the first groove, the right side of the flat fork is inserted into the second groove, and the bottom ends of the left and right sides of the flat fork are inserted into the third groove 9 of the flat fork bottom fixing seat 4; the push cylinder 6 is activated to drive the left and right fixing seats to move towards the middle, so that the bottom ends of the left and right sides of the flat fork are aligned and close to the flat fork connecting block; then the flat fork top pressing cylinder 5 is activated to press down the output end to fix the top ends of the left and right sides of the flat fork; at the same time, the flat fork connecting block pressing cylinder 8 presses one side of the connecting block, and the other side contacts the abutment block to complete the positioning of the connecting block.

[0016] After positioning, welding is performed. The magnetic attraction force and the pressure of the clamping cylinder work together to prevent the parts from shifting. After welding, the clamping cylinder and push cylinder 6 are released, and the finished product is removed.

[0017] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
