DETAILED DESCRIPTION OF EMBODIMENTS

Embodiment 1

(5) The present invention is further illustrated as follows in combination with the drawings and specific embodiments.

(6) As shown in FIG. 1 and FIG. 2, the self-adaptive hub burr removing device according to the present invention is composed of a workbench 1, columns 2, a brush 3, a spindle 4, a spindle box 5, a cross beam 6, a spindle motor 7, a controller 8, a clamp 10, a parallel robot 11, a displacement sensor 12 and other components. The columns 2 are fixedly connected to the workbench 1, the cross beam 6 is connected to the columns 2 by bolts or guide rails, and the position of the cross beam 6 is adjustable along the columns 2. The spindle box 5 is connected to the cross beam 6, and can translate on the cross beam 6. The spindle 4, the spindle motor 7 and the controller 8 are arranged on the spindle box 5. The brush 3 is connected to the end of the spindle 4. The displacement sensor 12 is arranged inside the brush 3, and the specific type and quantity of the displacement sensor 12 can be selected according to actual needs. The displacement sensor 12 can feed back position information of the surface of a hub 9 approaching thereto in real time. The hub 9 is fixed to the parallel robot 11 by the clamp 10. The parallel robot 11 can implement precise adjustment, and can perform real-time posture adjustment according to the instruction of the controller 8 to ensure that the brush 3 is always in close contact with the back cavity of the hub, thereby achieving a good burr removing effect.
