After the wheel hub reaches the second inspection station 20, the second inspection station 20 inspects the center hole diameter, cap groove diameter, and cap groove depth of the wheel hub. The third inspection station 30 inspects the bolt hole position, PCD pitch circle concentricity with the center hole, and bolt hole diameter of the wheel hub. The marking station 40 marks the good wheel hubs after the inspection is completed.

[0031] In this embodiment, the wheel hub online dimension inspection machine further includes a transverse pressing component 50 and a frame 60. The first inspection station 10, the second inspection station 20, the third inspection station 30 and the marking station 40 are arranged sequentially along the length direction of the frame 60.

The transverse pressing component 50 can press down and position the wheel hub so that the wheel hub can be stably inspected at the first inspection station 10, the second inspection station 20 and the third inspection station 30.

[0032] Specifically, the transverse pressing assembly 50 of this embodiment includes a transverse module 51, a pressing module 52, and a pressing block 53. The transverse module 51 is arranged along a first direction. The transverse module 51 drives the pressing module 52 along the first direction. The pressing module 52 drives the pressing block 53 to press down and position the wheel hub. When the wheel hub reaches the corresponding detection station, the transverse module 51 drives the pressing module 52 above the wheel hub. The pressing module 52 then drives the pressing block 53, and the pressing block 53 presses down and positions the wheel hub.

[0033] Specifically, in this embodiment, the transverse module 51 is a servo motor module, the pressing module 52 is a drive cylinder, and the pressing block 53 is provided with a pressing protrusion 531 to press and position the wheel hub. The pressing protrusion 531 on the pressing block 53 can cooperate with the wheel hub to accurately press and position the wheel hub.

[0034] Combination Figure 1 and Figure 2As shown, the first inspection station 10 includes a first conveyor line 11 and several cameras 12 located above the first conveyor line 11. In this embodiment, the cameras 12 include 3D cameras and CCD cameras, thereby identifying and measuring the wheel shape, wheel height, and wheel offset of the wheel hub. The second inspection station 20 includes a second conveyor line 21 and a coordinate measuring machine 22 located above the second conveyor line 21. In this embodiment, the coordinate measuring machine 22 uses a probe to perform contact testing on the wheel hub, thereby measuring the diameter of the center hole and the diameter of the cap groove of the wheel hub. The third inspection station 30 includes a third conveyor line 31 and a visual image flash tester 32 located above the third conveyor line 31. In this embodiment, the visual image flash tester 32 is used to inspect the position of the bolt holes, the concentricity of the PCD pitch circle and the center hole, and the diameter of the bolt holes of the wheel hub. The marking station 40 includes a fourth conveyor line 41 and a marking machine 42. The fourth conveyor line 41 conveys the wheel hub, and the marking machine 42 marks the wheel hub. When the inspection result of the wheel hub is qualified, the marking machine 42 marks it.

The positioning cylinder 71 drives the positioning carrier plate 72 closer to the wheel hub, and the positioning protrusions 721 enter the holes of the wheel hub to position the wheel hub. When the wheel hub reaches the first inspection station 10, the positioning cylinder 71 of the positioning component 70 lifts the positioning carrier plate 72, so that the positioning protrusions 721 enter the wheel hub to position the wheel hub so that the wheel hub can be inspected subsequently.

[0037] In this embodiment, the second inspection station 20 also includes an inspection platform 23, a second conveyor line 21 and a coordinate measuring machine 22, all of which are installed on the inspection platform 23. In this embodiment, the inspection platform 23 is a marble platform so that the coordinate measuring machine 22 can inspect the wheel hub.

The clamping assembly 80 includes a clamping module 81 and two sets of clamping wheels 82 arranged opposite to each other. The clamping module 81 drives one set of clamping wheels 82, while the other set of clamping wheels 82 is fixed on the fourth conveyor line 41. When the two sets of clamping wheels 82 come close together, they clamp and position the wheel hub. In this embodiment, the clamping module 81 is a linear module that drives one set of clamping wheels 82. The two sets of clamping wheels 82 clamp and position the wheel hub so that the marking machine 42 can perform marking operations on the wheel hub.

[0039] In practical use, the wheel hub online dimensional inspection machine of this embodiment continuously inspects wheel hubs through a first inspection station 10, a second inspection station 20, a third inspection station 30, and a marking station 40 set sequentially, and marks good wheel hubs. It realizes online dimensional inspection of parameters such as hole depth, center hole diameter, and center hole concentricity of the wheel hub, which greatly improves the inspection efficiency of wheel hubs. No manual operation is required in this process, avoiding the occurrence of human error. Therefore, while improving the inspection efficiency of wheel hubs, it can also ensure the inspection accuracy of wheel hubs.
