DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Embodiment 1, refer to Figures 1 to 2A wheel hub grabbing arm comprises a connecting seat 1, a fixed grabbing frame 2 is welded to the outer wall of one side of the connecting seat 1, and the inner walls at both ends of the fixed grabbing frame 2 are rotatably connected with movable grabbing plates 3, a grabbing cylinder 4 is hinged between the fixed grabbing frame 2 and the movable grabbing plate 3, and the inner walls of the fixed grabbing frame 2 and the movable grabbing plate 3 are respectively installed with symmetrically distributed first positioning wheels 5 and second positioning wheels 6.

[0023] In this embodiment, when the fixed grabbing frame 2 moves to the vicinity of the wheel hub, the movable grabbing plate 3 is pushed by the two grabbing cylinders 4. The grabbing cylinders 4 push the movable grabbing plate 3 to be close to the wheel hub, and rely on the positioning of the first positioning wheel 5 and the second positioning wheel 6 to fix the wheel hub between the fixed grabbing frame 2 and the movable grabbing plate 3, thereby realizing automatic grabbing of the wheel hub, which is fast and convenient and saves manpower.

[0024] Example 2, refer to Figure 3 A hub grabbing arm, a connecting seat 1 is fixedly connected to the outer wall of one side with a rotating cylinder 7, and the piston rod of the rotating cylinder 7 is fixedly connected to a connecting plate 8, and a bottom plate 9 is welded to the outer wall at the bottom of the connecting plate 8.
