The flange and the axle head are fixed together by welding, and the flange is fixedly installed on the bridge tube. Currently, when welding and fixing the axle head to the flange, due to the lack of a special tooling for positioning between the flange and the axle head, after the axle head is welded to the flange, the coaxiality between the axle head and the flange is relatively low. After being assembled with the brake drum, it is likely to be in a state where it cannot rotate. Therefore, a special welding tooling for positioning between the flange and the axle head is needed to ensure the welding coaxiality between the flange and the axle head. Summary of the Utility Model

The connecting sleeve is fixedly installed at the left end of the positioning sleeve, and the positioning mechanism is installed at the left end of the connecting sleeve. The positioning mechanism is used to position the flange. The positioning sleeve, the connecting sleeve and the positioning mechanism are coaxial. The positioning hole on the positioning sleeve is adapted to the outer diameter of the axle head. When welding between the flange and the axle head, place the bridge tube on the support, then pass the axle head through the positioning hole of the positioning sleeve and press against the left end of the flange. Then, position the flange through the positioning mechanism to make the axle head and the flange coaxial. Then, fix and weld the flange and the axle head through an external welding device. Since the axle head passes through the positioning hole of the positioning sleeve, and the positioning hole on the positioning sleeve is adapted to the outer diameter of the axle head, the axle head is coaxial with the positioning sleeve. Since the positioning sleeve, the connecting sleeve and the positioning mechanism are coaxial, the coaxiality of the flange and the axle head during welding can be ensured through the positioning mechanism. It can ensure that the flange and the axle head are always in a coaxial state during welding, improve the coaxiality of the flange and the axle head after welding, is convenient to use, and has high reliability.

[0005] Preferably, the positioning mechanism includes a positioning disk and multiple groups of positioning pins. The positioning disk is fixedly installed at the left end of the connecting sleeve, and multiple groups of positioning pins are fixedly installed at the left end of the positioning disk. The multiple groups of positioning pins are circumferentially distributed around the axis of the positioning sleeve. When welding the flange and the shaft head, insert the multiple groups of positioning pins on the positioning disk into the multiple mounting holes on the flange. Then, pass the shaft head through the positioning hole of the positioning sleeve and make it close to the right end of the flange. After that, the worker can weld the contact part between the flange and the shaft head through an external welding mechanism. By inserting multiple groups of positioning pins into multiple mounting holes on the flange, the coaxiality between the flange and the shaft head is ensured. At the same time, relative rotation between the flange and the shaft head during the welding process is prevented, improving the welding accuracy and reliability.

[0006] Preferably, it further includes a handle. The handle is fixedly installed at the upper end of the connecting sleeve. With the above setting, the worker can grasp the handle to move the connecting sleeve, which is convenient for carrying.
