The fifth buffer 722 may play a role in buffering and protecting the second sliding block 72, and the sixth limiting member 723 may play a role in limiting the second sliding block 72, so as to limit the stroke of the second heating member 8 in the X-axis direction.

In an embodiment, please refer to fig. 2 and fig. 6, as a specific implementation of the welding apparatus provided in the embodiment of the present application, the welding apparatus further includes a second clamping seat 40 for cooperating with the material clamping claw 31 to clamp the sidewall of the oil tank; the second clamping seat 40 is mounted on the second sliding block 72, and the second clamping seat 40 is spaced apart from the second heating member 8. With this structure, the second chuck 40 can be disposed to face the material-holding claw 31 by the driving of the traverse unit 7. When weldment 33 welds, second grip slipper 40 can realize pressing from both sides tightly the oil tank lateral wall with the cooperation of pressing from both sides material claw 31, and then improves the welding effect between weldment 33 and the oil tank, avoids rocking of oil tank to influence welding quality.

In an embodiment, referring to fig. 2, as a specific implementation of the welding apparatus provided in the embodiment of the present application, the first supporting arm 2 and the second supporting arm 3 are located at the same side of the supporting plate 1, and the first supporting arm 2 and the second supporting arm 3 are distributed in a central symmetry manner around the center of the supporting plate 1. In particular, the first support arm 2 and the second support arm 3 are both in an "L" configuration. Through "L" type structural design, the inside of being convenient for first support arm 2 and second support arm 3 by the through-hole on the oil tank stretch into to the oil tank realizes the welding operation to the oil tank is inside. This structure, locate the homonymy of backup pad 1 with first support arm 2 and second support arm 3, at the in-process of adjusting first support arm 2 and second support arm 3, only need through 9 rotatory backup pads 1 of robotic arm can to reducible backup pad 1's removal or rotation stroke, and then improve welding efficiency.

The application provides a welding equipment's concrete welding step as follows:

1. the oil tank supported and transported by the assembly line is positioned and fixed by the positioning mechanism;

2. the mechanical arm 9 drives the supporting plate 1 to enable one end, provided with the first heating member 21, of the first supporting arm 2 to extend into the oil tank, and the first heating member 21 heats the welding position; at the same time, the second heating member 8 heats the solder 33 on the clamping claw 31. Specifically, the second power member 30 drives the first support arm 2 to move, the power unit 5 drives the first clamping seat 10 to move, so that the first clamping seat 10 is close to the first heating member 21, the first clamping seat 10 and the first heating member 21 clamp the side wall of the oil tank, and the first heating member 21 heats the welding position in the oil tank. The drive unit 4 drives the second support arm 3 to move, and the lifting unit 6 drives the second heating member 8 to move, so that the clamping claw 31 is close to the second heating member 8, the second heating member 8 heats the welding member 33 on the clamping claw 31, the synchronous operation of oil tank heating and welding member 33 heating is realized, and the welding efficiency is further improved.

3. The mechanical arm 9 continues to drive the support plate 1, so that the end, provided with the first heating element 21, of the first support arm 2 is pulled out from the inside of the oil tank, the end, provided with the clamping claw 31, of the second support arm 3 extends into the inside of the oil tank, and the welding is realized after the welding piece 33 is aligned with the welding position by the clamping claw 31. Specifically, the traverse unit 7 drives the second gripper base 40 to move along the X axis so that the second gripper base 40 is aligned with the gripper jaw 31. After one end of the second support arm 3 provided with the clamping claw 31 extends into the oil tank and is aligned with the welding position, the driving unit 4 drives the second support arm 3 to move, the lifting unit 6 drives the second clamping seat 40 to move, so that the clamping claw 31 and the second clamping seat 40 are close to each other, the clamping claw 31 is matched with the second clamping seat 40 to clamp the side wall of the oil tank, and the welding piece 33 is welded with the welding position.

4. The robot arm 9 drives the support plate 1 again to pull out the end of the second support arm 3 provided with the material clamping claw 31 from the inside of the oil tank. The welded oil tank can be transported to the next station by the assembly line.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
