[0022] A control panel 15 is fixedly mounted on one side surface of the right side panel 2 .

[0023] See also Figure 1 and Figure 2 In this embodiment, the detection assembly includes a positioning plate 5 fixedly mounted on the movable end of the hydraulic cylinder 4, a detection member is disposed on the lower surface of the positioning plate 5, and guide members are disposed on both side surfaces of the positioning plate 5.

[0024] Among them, the detection part includes a fixed cylinder 6 fixedly installed on the lower surface of the positioning plate 5, a positioning rod 8 is fixedly installed on the inner top wall of the fixed cylinder 6, and a plurality of infrared rangefinders 7 are fixedly installed on the inner wall of the fixed cylinder 6, and the output ends of the plurality of infrared rangefinders 7 face one side of the positioning rod 8.

[0025] Since the distance between the infrared rangefinder 7 and the positioning rod 8 is fixed, when the automobile wheel hub blocks the light emitted by the infrared rangefinder 7, the radius of the automobile wheel hub can be calculated, thereby obtaining the diameter of the automobile wheel hub.

[0026] It should be noted that the distance between the infrared rangefinder 7 and the positioning rod 8 is greater than 73 centimeters.

[0027] It should be noted that the infrared rangefinder 7 is a prior art, and its specific structure and working principle are not described in detail herein.

[0028] Secondly, the guide member includes guide rods 16 fixedly mounted on both sides of the top plate 3, the other ends of the two guide rods 16 are fixedly connected to the upper surface of the base 1, the surfaces of the two guide rods 16 are slidably sleeved with guide blocks 9, and the other ends of the two guide blocks 9 are fixedly connected to the surface of the positioning plate 5. The positioning plate 5 is guided by the guide blocks 9, so that the positioning plate 5 can be stably moved vertically.

[0029] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the clamping member includes an axial rod 10 fixedly mounted on the upper surface of a workbench 14. The axial rod 10 is located directly below the positioning rod 8 and has an alignment groove on its upper surface that is the same size as the positioning rod 8. An annular groove is provided on the surface of the axial rod 10. An airbag 11 is fixedly mounted on the inner wall of the axial rod 10. A plurality of support plates 12 are fixedly mounted on the other side surface of the airbag 11. A rubber pad is fixedly mounted on the side surface of the plurality of support plates 12 away from the airbag 11. An air pump 13 is fixedly mounted on the upper surface of the base 1. An air pipe extending to the interior of the workbench 14 and connected to the interior of the airbag 11 is fixedly mounted on the output end of the air pump 13.

[0030] By providing the airbag 11, when the airbag 11 expands, it can drive the support plate 12 to move, so that the device can fix the axis of the automobile wheel hub of different sizes.

[0031] Among them, a plurality of rubber bands 17 in annular shape are slidably inserted inside the plurality of support plates 12 .

[0032] By providing the rubber band 17 , a plurality of support plates 12 can be always fixedly connected together.

[0033] The working principle of the above embodiment is as follows: the staff places the automobile wheel hub on the workbench 14 so that the axial rod 10 passes through the axis of the automobile wheel hub, and the air pump 13 is started to inflate the airbag 11, so that the airbag 11 expands, so that the support plate 12 can move, thereby fixing the automobile wheel hub. At this time, the hydraulic cylinder 4 is started, thereby driving the positioning plate 5 to move downward, so that the fixing tube 6 is sleeved on the automobile wheel hub. At this time, the automobile wheel hub blocks the light emitted by the infrared rangefinder 7, so that the control panel 15 obtains the distance from the infrared rangefinder 7 to the surface of the automobile wheel hub. Since the distance between the infrared rangefinder 7 and the positioning rod 8 is fixed, the radius of the automobile wheel hub can be converted to obtain the diameter of the automobile wheel hub. Through the above operation, the staff only needs to place the automobile wheel hub on the workbench 14 to detect the diameter of the automobile wheel hub.
