[0002] A hub bearing is a key component between an automobile wheel hub and an axle. It plays a crucial role during vehicle driving. Specifically, the hub bearing can not only support the wheel, but also allow the wheel to rotate freely on the axle. Moreover, the hub bearing can well withstand the vertical load and lateral force from the vehicle weight.

[0003] A hub bearing usually includes structures such as an inner flange, an outer flange, and a bearing body. The inner flange and the outer flange are usually annular. To manufacture a hub bearing, after producing the aforementioned components, it is also necessary to detect components such as the inner flange and the outer flange to meet the assembly requirements. Typically, whether it is the inner flange or the outer flange, at least two items need to be detected, namely inner end face detection and flange tooth detection. Usually, existing general-purpose eddy current detection equipment is used to detect components, and eddy current detection characteristics are used for detection and flaw detection.

[0004] When using existing general-purpose eddy current detection equipment to detect components, workers need to hold and rotate the components, and also need to adjust the position of the components from time to time. Workers are involved more in the above-mentioned component detection, and the efficiency is not high. Summary of the Invention In order to improve the detection efficiency, this application provides an eddy current detector for hub bearings.

Detailed Embodiment

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0026] An embodiment of the present application discloses a hub bearing eddy current detector, which is used to improve the detection efficiency of parts. In this embodiment, taking the detection of a ring-shaped part, such as an outer flange, as an example.

[0027] Referring to Figure 1 , the hub bearing eddy current detector includes a workbench 1. A frame 11 is installed on the workbench 1. A first manipulator 12 is installed on the frame 11. The first manipulator 12 is provided with a clamping and rotating mechanism 2. The clamping and rotating mechanism 2 can clamp the part and drive the part to rotate. A second manipulator 13 is provided on the workbench 1. A detection mechanism 3 is installed on the second manipulator 13. The detection mechanism 3 can perform inner end face detection and flange tooth detection on the rotating part. The workbench 1 is also provided with a feeding mechanism 4 for feeding and placing the part on the clamping and rotating mechanism 2 and a discharging mechanism 5 for discharging the part.

[0028] First, use the feeding mechanism 4 to place the part on the clamping and rotating mechanism 2, then use the clamping and rotating mechanism 2 to drive the part to rotate. At this time, drive the second manipulator 13 and the detection mechanism 3 to perform inner end face detection and flange tooth detection on the part, and then drive the discharging mechanism 5 to discharge the part.

[0029] The structures involved in the above action sequence will be described in turn: Referring to Figure 1 and Figure 2 , the feeding mechanism 4 includes a belt conveyor 41 installed on the workbench 1. The belt conveyor 41 is used to receive the parts transferred from the previous process for part feeding. The specific structure of the belt conveyor 41 is the prior art, so it will not be elaborated here. A clamping part 42 is installed on the detection mechanism 3. The clamping part 42 is a clamping cylinder. A rubber pad 43 is provided on the clamping end of the clamping part 42. The rubber pad 43 can protect the shape of the part.

[0030] After the belt conveyor 41 transfers the parts from the previous process to one side of the second manipulator 13, drive the second manipulator 13 to drive the clamping part 42 to move to clamp the parts on the belt conveyor 41 onto the clamping and rotating mechanism 2 to complete the feeding.

[0031] Referring to Figure 3 and Figure 4 , the clamping and rotating mechanism 2 includes a driving and rotating part 21. The driving and rotating part 21 is preferably a rotary cylinder. The driving and rotating part 21 is installed on the first manipulator 12. A supporting seat 22 for placing the part is installed on the output end of the driving and rotating part 21. A clamping assembly 23 is installed on the supporting seat 22. The clamping assembly 23 can maintain / release the clamping of the part.

[0032] Referring to Figure 3 and Figure 4, Specifically, the supporting base 22 includes a bottom plate 221 connected to the driving and rotating member 21. A plurality of support rods 222 are connected to the upper end of the bottom plate 221. A support ring 223 for placing components is connected to the plurality of support rods 222. The clamping assembly 23 is installed on the support ring 223. A clamping adjustment member 224 is installed on the upper end of the bottom plate 221. The clamping adjustment member 224 is a two-jaw cylinder. The clamping adjustment member 224 is located below the support ring 223 and is used to further clamp the components and adjust the position of the components.

[0033] Refer to Figure 4 and Figure 5 , the support ring 223 includes a receiving hole 2231 in the middle for placing components; the clamping assembly 23 includes a plurality of sliding members 231. The plurality of sliding members 231 are evenly distributed along the circumferential direction of the support ring 223. The installation structures of each sliding member 231 are the same. Taking the installation structure of one of the sliding members 231 as an example: a sliding groove 2232 is formed in the inner wall of the support ring 223 corresponding to each sliding member 231. The sliding member 231 is slidably connected to the sliding groove 2232. One end of the sliding member 231 is located in the receiving hole 2231; a spring 232 is further provided in the sliding groove 2232. One end of the spring 232 is connected to the sliding member 231, and the other end is connected to the support ring 223; when the component is inserted into the receiving hole 2231, the sliding member 231 will move away from the receiving hole 2231 under the action of friction, and at this time the spring 232 is compressed. Specifically, the sliding member 231 includes a sliding block 2311 slidably connected to the sliding groove 2232. The sliding block 2311 includes an upper inclined portion 2312 and a lower inclined portion 2313 at one end close to the receiving hole 2231. Both the upper inclined portion 2312 and the lower inclined portion 2313 are inclined inward away from the spring 232.

[0034] The manipulator II 13 and the clamping member 42 insert the component and place it in the receiving hole 2231. The component entering the receiving hole 2231 will squeeze the sliding member 231 to move away from the receiving hole 2231, and the spring 232 is compressed. The spring 232 will provide a squeezing force for the sliding member 231 to complete the clamping of the component; the driving clamping adjustment member 224 further clamps the component and adjusts the position at the same time.

[0035] Using the elasticity of the spring 232 to enable the sliding member 231 to clamp the component can prevent structural damage to the component and cause deformation of the component. In this application, due to double clamping, it is not necessary to set too large a clamping force for the clamping adjustment member 224 to ensure the stability of the component.

[0036] Refer to Figure 2, the inspection mechanism 3 includes a connecting plate 31 which is installed on the second manipulator 13. An eddy current detector 32, a lighting member 33 and a CCD camera 34 are installed on the second manipulator 13. The eddy current detector 32 only needs to approach the component and move along one side of the component to complete the inspection of the component. The specific structures and inspection logics of the eddy current detector 32, the lighting member 33 and the CCD camera 34 are all prior arts, so they will not be elaborated here.

[0037] Referring to Figure 6 , the blanking mechanism 5 includes a first belt conveyor 51, a second belt conveyor 52 and a third belt conveyor 53 arranged on the workbench 1. The first belt conveyor 51 is used for blanking qualified products, the second belt conveyor 52 is used for blanking unqualified products with inner end face inspection, and the third belt conveyor 53 is used for blanking unqualified products with flange tooth inspection.

[0038] The implementation principle of the hub bearing eddy current detector in the embodiment of the present application is as follows: After the belt conveyor 41 transfers the components from the previous process to one side of the second manipulator 13, the second manipulator 13 is driven to drive the clamping member 42 to move to clamp the components on the belt conveyor 41 and place them into the receiving hole 2231. The components entering the receiving hole 2231 will squeeze the sliding member 231 to move away from the receiving hole 2231, and the spring 232 is compressed. The spring 232 will provide a squeezing force for the sliding member 231 to clamp the components; the clamping and positioning member 224 is driven to further clamp and position the components at the same time; the driving member 21 is driven and cooperated with the second manipulator 13 and the eddy current detector 32 to complete the inspection of the components; then after the clamping and positioning member 224 releases the clamping of the components, the second manipulator 13 and the clamping member 42 are driven to clamp and classify the components and place them on one of the first belt conveyor 51, the second belt conveyor 52 and the third belt conveyor 53 to complete blanking.
