Description

Technical Field

[0001] The utility model relates to the technical field of wheel rim processing, in particular to a clamping and positioning mechanism of a wheel rim wire locking and positioning machine. Background Art

[0002] The electric wheel is composed of a rim, a hub and spokes. The hub is located inside the rim, and the two are at the same center. The spokes are connected between the hub and the rim. The rim contacts the ground to play a rolling role for the electric vehicle. There are multiple spokes, which surround the outer periphery of the hub and are connected to the rim to strengthen the support when the vehicle is driving. When making the wheel, first put the rim on the workbench, then put the hub at the center of the rim, and then connect the spokes one by one between the hub and the rim. During assembly, due to the lack of reasonable positioning tooling, the rim and the hub are positioned.
