[0033] Example 1

[0034] like Figure 1-2 As shown, this utility model embodiment provides a quick assembly tooling for wheel rim end caps, used to set two end cap units at both axial ends of an iron ring 83. The quick assembly tooling for wheel rim end caps includes two locking units and two suction units. The two suction units are respectively located on the side of the two end cap units that are close to each other. The two locking units are respectively inserted into the shaft holes of the two end cap units and are detachably connected to the two suction units on the inner side of the two end cap units, so as to lock the two suction units on the side of the two end cap units that are close to each other and to block the shaft holes of the two end cap units.

[0035] When the two end cap units are respectively sealed and fastened to the two axial ends of the iron ring 83, the two suction units can be suctioned together.

[0036] In this embodiment, the quick assembly fixture for the rim end cap includes a locking unit and two suction units. The two suction units are located on the side of the two end cap units that are close to each other. The two locking units are respectively inserted into the shaft holes of the two end cap units and are detachably connected to the two suction units on the inner side of the two end cap units, which facilitates the assembly and disassembly of the two end cap units and the two suction units. The detachable connection of the two suction units on the inner side of the two end cap units can lock the two suction units on the side of the two end cap units that are close to each other and seal the shaft holes of the two end cap units. After the shaft holes of the two end cap units are sealed, the electrophoretic liquid and paint can be prevented from entering the inner side of the rim end cap through the shaft holes. The two end cap units are respectively sealed and fastened to the axial ends of the iron ring 83, which can prevent the electrophoretic liquid and paint from entering the inner side of the rim end cap through the mating points between the two end cap units and the axial ends of the iron ring 83.

[0037] Specifically, the two suction units are a first suction cup 11 and a second suction cup 12, the two locking units are a first locking unit and a second locking unit, and the two end cap units are a first end cap unit 81 and a second end cap unit 83.
