[0019] A grabbing device for forging a wheel hub comprises a frame 1, a clamping mechanism 7 is installed on the frame 1 through a driving mechanism, the driving mechanism can drive the clamping mechanism 7 to move horizontally and lift, the clamping mechanism 7 comprises a sleeve 8, a threaded seat 9 is arranged on the upper part of the sleeve 8, a threaded rod 13 is connected to the threaded seat 9, a conical block 10 is arranged in the sleeve 8, the diameter of the lower end of the conical block 10 is smaller than the diameter of the upper end, a rotating seat 11 is arranged on the upper part of the conical block 10, a rotating disc 12 is rotatably arranged in the rotating seat 11, and a threaded rod 13 is arranged at the lower part of the sleeve 8. The end extends into the sleeve 8 and is connected to the turntable 12, the upper end of the threaded rod 13 is connected to the handwheel 14, the side of the sleeve 8 is penetrated by a sliding arm 16, the outer periphery of the sleeve 8 is connected to a support plate 18 above the sliding arm 16, and the support plate 18 is provided with a movable hole 19, the upper part of the sliding arm 16 is connected to a sliding rod 20, the upper end of the sliding rod 20 passes through the movable hole 19 and is connected to a mounting block 21, a spring 22 is connected between the mounting block 21 and the sleeve 8, and the inner end of the sliding arm 16 is against the outer periphery of the conical block 10.

[0020] The clamping mechanism 7 is moved to the top of the wheel hub by the driving mechanism, and then the clamping mechanism 7 is driven to descend so that part of it enters the wheel hub. The threaded rod 13 is rotated by the hand wheel 14, and the threaded rod 13 rotates in the threaded seat 9 to descend, thereby driving the conical block 10 to move downward. During the descent of the conical block 10, it will move outward against the sliding arm 16, so that the outer end of the sliding arm 16 is against the inner wall of the wheel hub, thereby fixing the wheel hub from the inside. After the clamping mechanism 7 is transported to the appropriate position by the driving mechanism, the threaded rod 13 is rotated in the opposite direction, so that the conical block 10 rises in the sleeve 8, and the sliding arm 16 will move inward under the action of the spring 22 to reset, thereby loosening the wheel hub.

[0021] Preferably, a movable hole 29 is opened on the support plate 18, and the movable hole 29 is located on the outside of the movable hole 19. A sliding rod 26 is passed through the movable hole 29. The lower end of the sliding rod 26 is connected to a clamping block 25, and the upper end of the sliding rod 26 is connected to a rack 24.
