[0038] Description of usage method: Preparation work:

[0039] Carefully carry the equipment to the working area where the rear axle welding is to be carried out. Select a spacious, obstacle-free and well-ventilated site to ensure safety and convenient operation during the welding process.

[0040] When placing the equipment, pay special attention to the contact situation between the welding support platform 1 and the ground to ensure that all four support points can land stably without obvious shaking or tilting.

[0041] Adjust the height:

[0042] Carefully observe whether the equipment is level. If the ground is uneven, each height-adjustable support foot 6 needs to be adjusted individually.

[0043] Hold the lever 19 with your hand and rotate it clockwise or counterclockwise. When rotating, apply appropriate force to avoid damaging the components due to excessive force.

[0044] While rotating the lever 19, observe the level state of the equipment until the entire welding support platform 1 is level, ensuring that the equipment can remain stable during subsequent welding operations.

[0045] Install the rear axle:

[0046] Carefully lift the rear axle of the electric tricycle and accurately place it on the rear axle welding equipment 4.

[0047] During the process of placing the rear axle, carefully align it with the positioning marks or reference lines on the rear axle welding equipment 4 to ensure the accurate position of the rear axle, so as to guarantee the welding accuracy and quality.

[0048] Adjust the welding height:

[0049] When operating the manual hydraulic pump 15, apply pressure slowly and evenly to avoid sudden strong operations that may damage the equipment components or cause deviations in the welding position.

[0050] As the secondary hydraulic rod equipment 14 expands and contracts, closely observe the rotation of the upper U-shaped support frame 8 and the lower U-shaped support frame 9.

[0051] Ensure that during the rotation process, the support plate body 3 always remains parallel to the horizontal plane. Tools such as a level can be used for auxiliary observation. If there are deviations, fine-tune the manual hydraulic pump 15 in a timely manner to ensure the stability of the rear axle welding equipment 4 and the accuracy of the welding position.

[0052] Perform welding:

[0053] Confirm that the parameter settings of the rear axle welding equipment 4 are correct, such as welding current, voltage, welding speed, etc.

[0054] After starting the rear axle welding equipment 4, the operator should wear protective equipment such as safety glasses and gloves and stand in a safe position for welding operations.

[0055] During the welding process, always pay attention to the welding quality. If there are any abnormalities, stop welding immediately and make adjustments.

[0056] The device is equipped with an easy-to-operate manual hydraulic pump 15, through which the height of the rear axle welding device 4 can be accurately controlled. This design allows the user to easily adjust the device to a suitable working height according to welding requirements, thereby improving the accuracy and efficiency of welding.

[0057] During the process of adjusting the height of the rear axle welding device 4, the support plate 3 is always kept parallel to the horizontal plane. This design not only enhances the stability of the device during operation, but also reduces potential risks caused by tilt or imbalance, thereby ensuring the safety of the operator.

[0058] Each support leg 5 of the device is provided with a height-adjustable support foot 6 at the end, which can be adjusted individually to adapt to uneven ground. This flexibility ensures that the welding support platform 1 can be quickly adjusted to a horizontal state even when the ground conditions are not ideal, ensuring the smooth progress of the entire welding process.

[0059] The design of the manual hydraulic pump 15 is simple and intuitive, and users can quickly learn and operate it without complex training. At the same time, the maintenance of the hydraulic system is relatively simple, reducing production delays caused by equipment failure.

[0060] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
