[0038] Usage description:

[0039] When using the rear axle welding bracket, first, the operator holds the handle 8 and rotates it. This action drives the screw rod 7 to rotate in the nut 6. As the screw rod 7 rotates, since its front end is connected to the joint bearing seat 12, and the joint bearing seat 12 is fixed to the front end of the sliding rod body 10, and the sliding rod body 10 slides on the auxiliary sliding sleeve body 9, it will push the sliding rod body 10 to move, thereby accurately adjusting the position of the movable positioning pulley 11.

[0040] During the adjustment process, since the extension directions of the auxiliary support plate 4 and the sliding rod body 10 are parallel to the extension directions of the screw rod 7 and the movable positioning pulley 11, this parallel structural design provides a stable guide for the movement of the movable positioning pulley 11, ensuring that it will not deviate or shake during the movement, and can withstand the pressure of the rear axle pipe and remain stable during use.

[0041] After the position of the movable positioning pulley 11 is adjusted, the rear axle pipe to be welded is placed between the fixed positioning pulley 13 and the movable positioning pulley 11 that has been adjusted into place.

[0042] Next, the operator starts the secondary electric telescopic rod 17 by operating the controller 24 on the rear side of the support platform 1. The secondary electric telescopic rod 17 begins to extend, and its telescopic portion drives the pressure sensor 18, the transmission plate body 19, the guide slide rod body 20, the auxiliary plate body 21 and the pressing type positioning pulley 22 to move downward together. When the pressing type positioning pulley 22 contacts and presses down on the rear axle tube, the pressure sensor 18 will monitor the pressing force applied to the rear axle tube in real time and transmit the data to the controller 24.

[0043] The controller 24 will intelligently control the telescopic action of the secondary electric telescopic rod 17 according to the preset pressure value range and the received real-time pressure data. If the pressure is too low, the controller 24 will control the secondary electric telescopic rod 17 to continue to extend and increase the pressing force; if the pressure is too high, the controller 24 will control the secondary electric telescopic rod 17 to retract and reduce the pressing force.

[0044] After ensuring the stable clamping and appropriate pressure of the rear axle tube, the welding operation can be started. After the welding is completed, the controller 24 will stop the work of the electric telescopic rod 17, and the push-type positioning pulley 22 will rise to release the rear axle tube.

[0045] After welding is completed, the operator can take out the welded rear axle pipe and prepare for the next step of processing or inspection.

[0046] The entire use process is highly automated, and the operation steps are simple and clear. It can easily adapt to both large and small rear axle pipe welding operations, significantly improving the efficiency and quality of rear axle welding while ensuring stability and safety during the welding process.

[0047] Precise adjustment: By holding the handle 8 and rotating it, the user can precisely adjust the position of the mobile positioning pulley 11. This design allows the user to easily adapt to rear axle tubes of different diameters, thereby greatly improving the practicality of the device.

[0048] Stability: The extension direction of the auxiliary support plate 4 and the sliding rod 10 is parallel to the extension direction of the screw rod 7 and the movable positioning pulley 11, which ensures that there will be no deviation or shaking during the movement. In addition, this structural design can withstand the pressure of the rear axle pipe during use and remain stable, thereby ensuring the accuracy of the welding process.

[0049] Automatic control: The controller 24 is used to start the secondary electric telescopic rod 17, driving the push-type positioning pulley 22 to move downward until it contacts the rear axle tube. This automatic step improves the stability of the welding process and reduces human errors.

[0050] Real-time monitoring: The pressure sensor 18 is installed at the lower part of the telescopic part of the secondary electric telescopic rod 17 to monitor and feedback the pressing force in real time. This design allows the user to understand the pressure on the rear axle pipe in real time during the welding process and make corresponding adjustments.

[0051] Uniform pressure distribution: The controller 24 adjusts the telescopic length of the electric telescopic rod 17 according to the feedback from the pressure sensor 18 to ensure that the rear axle tube is subjected to uniform and appropriate pressure during the welding process.

[0052] 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.
