Description

Technical Field

[0001] The utility model relates to the technical field of automobile wheel hub detection, in particular to an automobile wheel hub eddy current detection device. Background Art

[0002] Existing inspection methods for automobile wheel hubs usually include two methods: manual inspection and mechanical automatic inspection. Mechanical automatic inspection usually uses a transverse cylinder to control two jaws at the same time. The two jaws control loading and unloading respectively. The two jaws are continuously moved by the transverse cylinder to achieve synchronous loading and unloading. Since the distance between the two jaws is fixed, when one of the jaws is located at the inspection station, the other jaw is just located at the loading end / unloading end. After the unloading jaw grabs the inspected workpiece, the loading jaw located at the loading end of the workpiece is still a certain distance away from the inspection station. When the inspection time is fixed, the moving time of the loading jaw within this stroke determines the shortest time required for workpiece inspection, thereby reducing the efficiency of workpiece inspection.

[0003] Therefore, it is urgent to propose an automobile wheel hub eddy current testing device that can shorten the moving time of the feeding clamp. Utility Model Content

The feeding connecting plate 42 is fixedly connected to a feeding lifting cylinder 43. The output rod of the feeding lifting cylinder 43 is provided with a feeding clamp 44.

[0041] The material unloading component 5 includes a material unloading lifting cylinder 51 arranged on the material unloading connecting plate 32, and the output rod of the material unloading lifting cylinder 51 is provided with a material unloading clamping claw 52.

[0042] Specifically, a detection manipulator 7 is provided on the upper surface of the frame 1 , and an eddy current probe is provided on the detection manipulator 7 .

[0043] In one embodiment, the eddy current probe can be connected to a pressure sensor to implement overpressure and collision shutdown alarms.

[0044] Specifically, the upper surface of the frame 1 is provided with a detection station 8 and a standard sample station. The detection station 8 is arranged between the loading end and the unloading end of the frame 1. The standard sample station is arranged close to the unloading end of the frame 1. A standard sample workpiece is arranged on the standard sample station.

[0045] In one embodiment, the inspection station 8 includes a pneumatic rotary chuck.

[0046] Before the formal test, the standard sample workpiece on the standard sample station is grabbed by the unloading clamp 52 to the testing station 8, and the testing robot 7 moves the eddy current probe to the corresponding position walking track to perform sensitivity calibration.

[0047] Specifically, it also includes a conveying mechanism 9, which includes a loading conveyor line 91, an OK unloading conveyor line 92 and an NG unloading conveyor line 93.

[0048] If the inspection result of the workpiece to be inspected meets the requirements, the unloading clamp 52 places the workpiece to the loading end of the OK unloading conveyor line 92; if the inspection result of the workpiece to be inspected does not meet the requirements, the unloading clamp 52 places the workpiece to the loading end of the NG unloading conveyor line 93.

[0049] In order to facilitate the switching of the unloading position of the unloading clamp 52 between the OK unloading conveyor line 92 and the NG unloading conveyor line 93, as a further improvement, the unloading component 5 also includes a switching cylinder 53, the OK unloading conveyor line 92 and the NG unloading conveyor line 93 are arranged in the same line, the switching cylinder 53 is fixedly set on the unloading connecting plate 32, the output rod of the switching cylinder 53 is parallel to the feeding direction of the OK unloading conveyor line 92 and the NG unloading conveyor line 93, and the output rod of the switching cylinder 53 is fixedly connected to the unloading lifting cylinder 51.

[0050] The working principle of the utility model is:

[0051] When the previous workpiece is placed on the inspection station 8 by the loading clamp 44, the loading clamp 44 is located directly above the inspection station 8 and at one end of the movable bottom plate 3 close to the loading end of the frame 1, and the unloading clamp 52 is located directly above the loading end of the OK unloading conveyor line 92 or the NG unloading conveyor line 93, and then the large traverse cylinder 21 moves toward the loading end of the frame 1 until the loading clamp 44 is located directly above the loading conveyor line 91. At this time, the unloading clamp 52 is located Right above the inspection station 8, the loading clamp 44 then grabs the next workpiece while the unloading clamp 52 grabs the previously inspected workpiece. Then, the large traverse cylinder 21 moves toward the unloading end of the frame 1 while the small traverse cylinder 33 also moves toward the unloading end of the frame 1. Since the loading clamp 44 moves toward the unloading end of the frame 1 faster than the unloading clamp 52, the unloading clamp 52 has not yet reached the OK conveyor line or When the loading jaws 44 are directly above the loading end of the NG unloading conveyor line 93, the loading jaws 44 have arrived directly above the inspection station 8. At this time, the loading jaws 44 will continue to move toward the unloading end of the frame 1 driven by the large transverse cylinder 21. In order to ensure that the loading jaws 44 are always directly above the inspection workpiece to facilitate the loading jaws 44 to place the workpiece to be inspected on the inspection station 8, the small transverse cylinder 33 moves toward the loading end of the frame 1 at the same speed as the large transverse cylinder 21 to offset the influence of the large transverse cylinder 21 on the loading jaws 44. Finally, the loading jaws 44 place the workpiece to be inspected on the inspection station 8, while the unloading jaws 52 move to directly above the loading end of the OK unloading conveyor line 92 or the NG unloading conveyor line 93 and place the previously inspected workpiece on the loading end of the OK unloading conveyor line 92 or the NG unloading conveyor line 93. At this time, the unloading of the previous workpiece and the loading of the next workpiece are completed.
