Specifically, the material taking platform 12 is provided with a groove, the positioning arc plate 13 is slidably mounted in the groove, the bottom of the positioning arc plate 13 is provided with a positioning cylinder 14, and the top of the positioning arc plate 13 is provided with a taper. The top of the positioning arc plate 13 is excessively directed towards the center of the circle, so that a certain taper is formed. When the wheel rim shell is conveyed to the material taking platform 12, a sensor on the material taking platform 12 detects a signal, the controller controls the conveying belt 11 to stop running, meanwhile, the positioning air cylinder 14 jacks up the positioning arc plate 13, the taper at the top of the positioning arc plate 13 guides the inner wall of the wheel rim shell to a certain extent, and finally, the wheel rim shell is positioned to a position to be grabbed by utilizing the diameter of the positioning arc plate 13, and at the moment, the outer wall of the positioning arc plate 13 is attached to the inner wall of the wheel rim shell. When the feed conveyor 11 is started and the end position sensor fails to detect the wheel rim housing for a long period of time, a signal is sent to the controller reporting that the work piece is empty, which is replenished by the operator.
The manipulator 2 has three degrees of freedom at least, the manipulator 2 can adopt a frame type manipulator structure driven by a screw transmission or synchronous belt mechanism, and also can adopt a numerical control robot with high degree of freedom, the manipulator structure driven by the screw transmission or synchronous belt mechanism is suitable for workpieces with larger weight, and the numerical control robot is suitable for workpieces with lighter weight and narrower processing position.

The diameter of the clamping head 21 is slightly smaller than that of the central hole of the bottom surface of the wheel rim shell. When the jaws 22 are in the initial state, the jaws 22 are retracted inside the collet 21. When the wheel rim shell needs to be grabbed, the mechanical arm 2 drives the chuck 21 to be inserted into the center hole of the wheel rim shell, the chuck motor 23 drives the ring gear to rotate through the driving gear, so that the claw 22 is screwed out of the chuck 21, the claw 22 is contacted with the inner bottom surface of the wheel rim shell, and the wheel rim shell is lifted and transported. When the transfer is completed, the chuck motor 23 is controlled to rotate reversely, and the clamping jaws 22 are retracted into the chucks 21 again.
