Description

Technical Field

[0001] The present invention relates to the technical field of welding processing tooling, and specifically to a welding processing tooling for automotive half - shaft machining and its operation method. Background Art

[0002] The automotive half - shaft is a core component of the transmission system, responsible for transmitting the power of the gearbox to the wheels to drive the vehicle. Depending on the driving mode of the vehicle (front - wheel drive, rear - wheel drive, four - wheel drive), the layout and structure of the half - shaft will vary.

[0003] During the welding process, it is usually necessary to ensure that the weld seam is evenly heated and fully fused to guarantee the welding strength. However, when the automotive half - shaft cannot rotate after being fixed in the tooling, the staff can only try to complete the welding by adjusting the position and angle of the welding torch. This approach not only increases the operation difficulty but also may lead to uneven heating of the weld seam, resulting in welding defects such as slag inclusion and lack of fusion, seriously affecting the welding quality. Therefore, a welding processing tooling for automotive half - shaft machining and its operation method are proposed to address the above problems. Summary of the Invention

[0035] An operation method of a welding treatment tooling for automobile half shaft processing, this method uses the above-mentioned welding treatment tooling for automobile half shaft processing, and the method is as follows:

[0036] S1: Fit the side wall of the end cover 11 with the rotating disk 3 and place it between multiple abutting blocks 6, then rotate the threaded rod 5 to move the abutting block 6 to clamp the end cover 11, and then the end cover 11 can rotate with the rotating disk 3;

[0037] S2: Insert the shaft tube 13 between a pair of second arc-shaped blocks 19, and rotate the bidirectional threaded rod 16 to shorten the distance between the second arc-shaped blocks 19 to clamp the shaft tube 13;

[0038] S3: Rotate the gear 27 to drive the T-shaped plate 25 to move in the T-shaped groove 24, the T-shaped plate 25 will drive one end of the shaft tube 13 on the second support rod 12 to fit with the side wall of the end cover 11, and then weld the connection between the end cover 11 and the shaft tube 13.

[0039] Working principle: after the staff fits the side wall of the end cover 11 with the rotating disk 3, the staff rotates the threaded rod 5 to change the spacing between the stop blocks 6, so that the stop blocks 6 can clamp the end cover 11. Then the staff can clamp the shaft tube 13 on the second support rod 12 through the clamping piece and rotate it. After the shaft tube 13 and the end cover 11 are in contact, the staff can rotate the rotating disk 3 to drive the end cover 11 to rotate, and then weld the end cover 11 when it rotates, which reduces the operating difficulty of the staff and improves the welding quality. The staff rotates the bidirectional threaded rod 16, so that the bidirectional threaded rod 16 can shorten the distance between a pair of L-shaped blocks 17. The L-shaped block 17 then drives the first arc block 18 to move, so that when the shaft tube 13 is placed in the rotating member, the first arc block 18 can clamp the shaft tube 13. Under the action of the rotating member, the shaft tube 13 can be rotated in the clamped state. The second arc block 19 is in the arc groove. After the staff places the shaft tube 13 between a pair of second arc blocks 19, they rotate the bidirectional threaded rod 16 to clamp the shaft tube 13 between the second arc blocks 19. Then, the staff lifts the square block 20 to disengage it from the first square groove of the second arc block 19. In this way, the second arc block 19 can drive the shaft tube 13 to rotate in the first arc block 18. The staff pulls the round rod 21, and one end of the round rod 21 can be separated from the clamping groove 23 of the slider 14. At this time, the staff can lift the slider 14 to disengage from the second square groove, so that the components on the slider 14 are separated from the second support rod 12 along with the slider 14, and the second arc blocks 19 of different sizes can be easily replaced on the second support rod 12, so as to fix different types of shaft tubes 13.

After the shaft tube 13 is clamped by the second arc block 19, the staff can rotate the rotating rod 28 to drive the gear 27 to rotate, so that the rotation of the gear 27 drives the T-shaped plate 2 5 moves in the T-slot 24, so that the staff can drive one end of the shaft tube 13 to abut against the side wall of the end cover 11 by rotating the rotating rod 28, which is convenient for the staff to weld the connection between the end cover 11 and the shaft tube 13. Through a pair of L-shaped clamping blocks 30 on the abutting block 6, the L-shaped clamping block 30 can be separated from and inserted into the fixing block 29, and the abutting blocks 6 with different arcs can be replaced on the fixing block 29, which is convenient for fixing end covers 11 of different models. Since the top end of the second support rod 12 is in an arc shape, the second support rod 12 can lift the shaft tube 13 before the second arc block 19 clamps the shaft tube 13, which is convenient for the staff to clamp the shaft tube 13.
