Description

Technical Field

[0001] This application relates to the technical field of bearing riveting, and in particular to a riveting device and wheel hub bearing riveting equipment. Background Technology

[0002] In the manufacturing process of wheel hub bearings, riveting is required (such as the assembly of wheel hub bearing cages). Riveting makes the bearing unit more tightly packed and generates good preload, improving its reliability and lifespan. However, riveting carries the risk of scratching the surface of the wheel hub bearing. Therefore, good riveting head design and reasonable process parameters are key to improving riveting quality.

[0003] In existing technologies, after the wheel hub bearing is processed in the front-end process, it is transferred to the riveting station of a riveting device, where it is riveted using a riveting head. After riveting, it is then transferred to the rear-end process for the next step. However, such riveting devices typically use either a push-type or conveyor belt transfer method when transferring wheel hub bearings. The push-type transfer method causes sliding friction between the lower surface of the wheel hub bearing and the worktable surface, making the lower surface of the bearing prone to scratches. The conveyor belt transfer method has low positioning accuracy and requires an additional positioning mechanism, increasing equipment investment costs. Therefore, there is an urgent need for a riveting device to reduce the risk of scratches on wheel hub bearings during transfer and to improve the accuracy of wheel hub bearing transfer. Summary of the Invention

[0004] To reduce the risk of scratches on wheel hub bearings during transfer and to improve the accuracy of wheel hub bearing transfer, this application provides a riveting device and a wheel hub bearing riveting equipment.

[0005] Firstly, the riveting device provided in this application adopts the following technical solution:

[0006] A riveting device includes a transfer table, a riveting head, and a transfer mechanism. The transfer table has a riveting station, and the riveting head is disposed at the riveting station. The transfer mechanism includes a mounting plate, a lifting assembly for driving the mounting plate to move up and down, and a translation assembly for driving the mounting plate to move horizontally. The mounting plate is slidably mounted on one side of the transfer table. A first clamping seat and a second clamping seat are slidably mounted on the mounting plate. The mounting plate is provided with a first driving member for driving the first clamping seat and the second clamping seat to move closer to or further away from each other. The first clamping seat and the second clamping seat are each connected to a first clamping block, and a first clamping area is formed between the two first clamping blocks. The first clamping block has a clamping arc surface for abutting against the outer peripheral wall of the wheel hub bearing flange.

[0007] By adopting the above technical solution, after the wheel hub bearing is processed in the front-end process, it is placed on the transfer table. The translation component forces the mounting plate to move closer to the transfer table, then drives the first and second clamping seats to move closer together to clamp the wheel hub bearing. Next, the lifting component forces the lifting plate to rise, carrying the wheel hub bearing away from the surface of the transfer table. Then, the mounting plate can be driven to move along the conveying direction of the transfer table, transferring the wheel hub bearing to the riveting station for riveting operations. The lifting component ensures that the wheel hub bearing does not contact the transfer table surface during transfer, reducing the possibility of scratches on the bearing surface. Simultaneously, when the first and second clamping seats clamp the wheel hub bearing, the clamping arc surface of the first clamping block adapts to the outer peripheral wall of the wheel hub bearing flange, providing a positioning effect and improving the accuracy of the wheel hub bearing transfer.

[0008] Optionally, the clamping arc surface is provided with a support portion, and the top wall of the support portion forms a support surface for supporting the wheel hub bearing flange.

[0009] By adopting the above technical solution, when the first clamping block of the first clamping seat and the second clamping seat clamps the flange of the wheel hub bearing, the support surface of the support part supports the bottom of the flange of the wheel hub bearing, reducing the possibility of the wheel hub bearing slipping during the transfer process.

[0010] Optionally, the transfer table has a flaw detection station located at the rear end of the riveting station. The flaw detection station is equipped with a first probe for flaw detection on the surface of the wheel hub bearing. Multiple first and second clamping seats are arranged along the conveying direction of the transfer table, and the multiple first clamping seats and multiple second clamping seats are staggered to form multiple first clamping areas. The distance between the center of the riveting station and the center of the flaw detection station is adapted to the distance between the centers of two adjacent first clamping areas.

[0011] By adopting the above technical solution, the distance between the center of the riveting station and the center of the flaw detection station is adapted to the distance between the centers of two adjacent first clamping areas. This allows the wheel hub bearing in the first clamping area to be transferred to the riveting station for riveting when it is riveted, while the wheel hub bearing in the adjacent first clamping area (which has already been riveted) can be transferred to the flaw detection station for flaw detection. This allows the riveting head and the probe to work simultaneously, improving overall work efficiency.

[0012] Optionally, a first connecting strip connects two adjacent first clamping seats, and a second connecting strip connects two adjacent second clamping seats; the first driving component includes a driving gear, a first driving rack, a second driving rack, and a driving cylinder, the driving gear is rotatably mounted on the mounting plate, the first driving rack is disposed on the first clamping seat, the second driving rack is disposed on the second clamping seat, and the first driving rack and the driving gear, as well as the second driving rack and the driving gear, are meshed and transmitted; the driving cylinder is disposed on the mounting plate, and the piston rod of the driving cylinder is connected to the second clamping seat.

[0013] By adopting the above technical solution, multiple first clamping seats are connected into a whole by a first connecting strip, and multiple second clamping seats are connected into a whole by a second connecting strip. When clamping the wheel hub bearing, the second clamping seats are slidably driven by a drive cylinder. Under the action of the drive gear, the first drive rack, and the second drive rack, the multiple first clamping seats and the multiple second clamping seats can move synchronously, enabling the first clamping seats and the corresponding second clamping seats to clamp the wheel hub bearing, thus improving the operational convenience of the overall structure.

[0014] Optionally, the flaw detection station is equipped with a mounting base, which is connected to a base plate and a top plate respectively. The base plate is used for placing the bearing, and the first probe is set on the bottom wall of the top plate. The mounting base is equipped with a flipping assembly for flipping the wheel hub bearing.

[0015] By adopting the above technical solution, after the wheel hub bearing is riveted, it is transferred to the base plate of the mounting seat, and its upper surface can be inspected by the first probe; then the wheel hub bearing is flipped by the flipping assembly, so that the first probe can inspect its lower surface, thereby improving the comprehensiveness of the wheel hub bearing inspection.

[0016] Optionally, the flipping assembly includes a rotating disk, clamping bars, a second driving member, and a rotating member. The rotating disk is rotatably mounted on the mounting base. Two clamping bars are provided, and both clamping bars are slidably mounted on the rotating disk, forming a second clamping area between the two clamping bars. The second driving member is provided on the mounting base to drive the two clamping bars to move closer to each other, and the rotating member is provided on the mounting base to drive the rotating disk to rotate.

[0017] By adopting the above technical solution, after the wheel hub bearing is transferred to the base plate and the upper surface is inspected, the two clamping bars are forced to move closer to each other by the second driving component to clamp and fix the wheel hub bearing. Then, the rotating disk is driven to rotate, which can realize the wheel hub bearing flipping over and improve the operation convenience of the overall structure.

[0018] Optionally, a return spring is provided between the clamping bar and the rotating disk. The return spring normally forces the two clamping bars to move away from each other. The second driving component includes a push block, a lead screw, and a motor. Two push blocks are provided, each corresponding to one of the two clamping bars. Each push block is slidably mounted on the side wall of the mounting base. The lead screw is rotatably connected to the mounting base and is threaded through the two push blocks in sequence. The thread direction between the lead screw and the two push blocks is set to be opposite. The motor is mounted on the mounting base, and the output shaft of the motor is coaxially connected to the lead screw. When the two push blocks approach each other, the two push blocks push their respective corresponding clamping bars to reduce the second clamping area.

[0019] By adopting the above technical solution, under normal conditions, the two clamping bars are separated from each other by the action of the return spring, so as to facilitate the transfer of the wheel hub bearing from the transfer table to the base plate. After the wheel hub bearing is transferred to the base plate and the upper surface is inspected, the screw is driven to rotate, which drives the two pushing blocks to move closer to each other, so that the two pushing blocks push their respective clamping bars, enabling the two clamping bars to clamp and fix the wheel hub bearing on the base plate.

[0020] Optionally, the mounting base is provided with two limiting blocks on the side wall near the rotating disk, and two embedding holes are formed between the two limiting blocks. The two embedding holes are correspondingly set with two pushing blocks. When the two clamping bars clamp the wheel hub bearing, the pushing block moves into the corresponding embedding hole, and the two pushing blocks and the two limiting blocks combine to form a limiting ring surrounding the two clamping bars.

[0021] By adopting the above technical solution, the two pushing blocks approach each other, causing the two clamping strips to clamp and fix the wheel hub bearing. The two pushing blocks and the two limiting blocks combine to form a ring-shaped limiting ring. This allows the inner circumferential wall of the limiting ring to keep the two clamping strips in place when the rotating disk rotates, thus maintaining the clamping effect of the two clamping strips on the wheel hub bearing. This reduces the possibility of the two clamping strips loosening when the rotating disk rotates, which could cause the wheel hub bearing to fall off, and improves the overall flipping effect of the structure.

[0022] Optionally, both the base plate and the top plate are slidably mounted on the mounting base to enable lifting and lowering. The outer peripheral wall of the rotating disk is provided with a guide ring groove, and guide balls are connected to the side walls of both the base plate and the top plate. The guide balls are slidably embedded in the guide ring groove. The rotating disk is elliptical and has a major axis and a minor axis. When the major axis of the rotating disk rotates from the horizontal direction to the vertical direction, the base plate and the top plate move away from each other. When the major axis of the rotating disk rotates from the vertical direction to the horizontal direction, the base plate and the top plate move closer to each other.

[0023] By adopting the above technical solution, the guide ring groove and guide ball are arranged in series with the rotating disk, bottom plate, and top plate. This allows the rotating disk to force the bottom and top plates away from each other when the long axis of the rotating disk rotates from horizontal to vertical, providing clearance for the wheel hub bearing to be flipped and reducing the possibility of interference between the wheel hub bearing and the bottom plate during the flipping process. After the wheel hub bearing completes the flipping action, the bottom and top plates can move closer together, allowing the bottom plate to support the wheel hub bearing again, and the top plate to bring the first probe closer to the wheel hub bearing. This keeps the distance between the first probe and the wheel hub bearing within a reasonable range, thereby improving the flaw detection effect.

[0024] Secondly, the wheel hub bearing riveting equipment provided in this application adopts the following technical solution:

[0025] A wheel hub bearing riveting device includes a riveting worktable and the aforementioned riveting device.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Through the transfer mechanism, after the wheel hub bearing is processed in the previous stage, it is placed on the transfer table. A translation component forces the mounting plate to move closer to the transfer table, then drives the first and second clamping seats to move closer together to clamp the wheel hub bearing. Next, a lifting component forces the lifting plate to rise, carrying the wheel hub bearing away from the surface of the transfer table. Then, the mounting plate can be driven to move along the conveying direction of the transfer table, transferring the wheel hub bearing to the riveting station for riveting operations. The lifting component ensures that the wheel hub bearing does not contact the transfer table surface during transfer, reducing the possibility of scratches on the bearing surface. Simultaneously, when the first and second clamping seats clamp the wheel hub bearing, the clamping arc surface of the first clamping block adapts to the outer peripheral wall of the wheel hub bearing flange, providing a positioning effect and improving the accuracy of the wheel hub bearing transfer.

[0028] 2. With the addition of the flipping assembly, after the wheel hub bearing is riveted, it is transferred to the base plate of the mounting seat, and its upper surface can be inspected by the first probe; then the wheel hub bearing is flipped by the flipping assembly, so that the first probe can inspect its lower surface, thereby improving the comprehensiveness of the wheel hub bearing inspection.

[0029] 3. By setting the limiting blocks, the two pushing blocks move closer to each other, driving the two clamping strips to clamp and fix the wheel hub bearing. The two pushing blocks and the two limiting blocks combine to form a ring-shaped limiting ring. When the rotating disk rotates, the inner circumferential wall of the limiting ring can keep the two clamping strips in place, so that the two clamping strips maintain the clamping effect on the wheel hub bearing. This reduces the possibility that the two clamping strips will loosen when the rotating disk rotates, which could cause the wheel hub bearing to fall off, and improves the overall flipping effect of the structure.

[0040] The following combination Figures 1-9 This application will be described in further detail.

[0041] Example 1: This application discloses a riveting device.

[0042] Reference Figure 1 , Figure 2 A riveting device includes a transfer table 1, a riveting head 2, and a transfer mechanism 3. In this embodiment, the transfer table 1 is elongated, and the wheel hub bearing is transported along the length of the transfer table 1. The transfer table 1 has a riveting station 11 and a flaw detection station 12, with the flaw detection station 12 located at the rear end of the riveting station 11. The riveting head 2 is installed at the riveting station 11 for riveting the wheel hub bearing, and a first probe 13 for flaw detection of the wheel hub bearing surface is installed in the flaw detection station 12. The first probe 13 can be a vision camera (both the riveting head 2 and the first probe 13 are prior art, and their structures will not be described in detail here).

[0043] Reference Figure 3 , Figure 4The transfer mechanism 3 is used to transfer the wheel hub bearing. The transfer mechanism 3 includes a mounting plate 31, a lifting assembly, and a translation assembly. The mounting plate 31 is slidably mounted on one side of the transfer platform 1. The mounting plate 31 is elongated, and both ends of the mounting plate 31 extend along the length of the transfer platform 1. The lifting assembly is used to drive the mounting plate 31 to move up and down. The lifting assembly includes a lifting plate 34 and a lifting cylinder 35. The lifting plate 34 is located at the bottom of the mounting plate 31, and the lifting cylinder 35 is mounted at the bottom of the lifting plate 34. The piston rod of the lifting cylinder 35 is fixedly connected to the bottom wall of the lifting plate 34. When the piston rod of the lifting cylinder 35 extends outward, the lifting plate 34 is lifted upward. When the piston rod of the lifting cylinder 35 retracts inward, the lifting plate 34 moves downward.

[0044] The translation assembly is used to drive the mounting plate 31 to move. The translation assembly includes a sliding plate 36, a first translation cylinder 37 and a second translation cylinder. The sliding plate 36 is slidably mounted on the top wall of the lifting plate 34 so that it can slide along the width direction of the transfer table 1. The first translation cylinder 37 is installed between the lifting plate 34 and the sliding plate 36. When the first translation cylinder 37 is activated, it can drive the sliding plate 36 to slide along the width direction of the transfer table 1.

[0045] Mounting plate 31 is slidably mounted on sliding plate 36 so that it can slide along the length direction of transfer table 1. Second translation cylinder (not shown in the figure) is installed between sliding plate 36 and mounting plate 31. When the second translation cylinder is activated, it can drive mounting plate 31 to slide along the length direction of transfer table 1.

[0046] Reference Figure 3 , Figure 4 A first clamping seat 311 and a second clamping seat 312 are slidably mounted on the mounting plate 31. Multiple first clamping seats 311 and second clamping seats 312 are spaced apart along the length direction of the mounting plate 31 (i.e., along the conveying direction of the transfer table 1). The multiple first clamping seats 311 and multiple second clamping seats 312 are arranged in an alternating manner. A first clamping block 313 is fixedly installed on the side of each first clamping seat 311 and each second clamping seat 312 near the riveting station 11. A first clamping area 314 is formed between the first clamping block 313 of the first clamping seat 311 and the first clamping block 313 of the adjacent second clamping seat 312. Multiple first clamping seats 311 and multiple second clamping seats 312 are combined to form multiple first clamping areas 314.

[0047] It should be noted that, in this embodiment, the distance between the center of the riveting station 11 and the center of the flaw detection station 12 is adapted to the distance between the centers of two adjacent first clamping areas 314; the side wall of the first clamping block 313 near the first clamping area 314 has a clamping arc surface 315, which is used to abut against the outer peripheral wall of the wheel hub bearing flange. A support portion 316 is provided protruding from the clamping arc surface 315, and the support portion 316 is integrally formed with the first clamping block 313. The top wall of the support portion 316 forms a support surface 317 for supporting the wheel hub bearing flange.

[0048] Reference Figure 4 , Figure 5 A first connecting strip 32 connects two adjacent first clamping seats 311, and multiple first clamping seats 311 are connected in series through multiple first connecting strips 32 to form a whole. A second connecting strip 33 connects two adjacent second clamping seats 312, and multiple second clamping seats 312 are connected in series through multiple second connecting strips 33 to form a whole. The mounting plate 31 is provided with a first driving member 4, which is used to drive the first clamping seats 311 and adjacent second clamping seats 312 to move closer or further apart, so as to expand or shrink the first clamping area 314.

[0049] The first driving component 4 includes a driving gear 41, a first driving rack 42, a second driving rack 43, and a driving cylinder 44. The driving gear 41 is rotatably mounted on the mounting plate 31. The first driving rack 42 is fixedly mounted on the bottom wall of one of the first clamping seats 311, and the second driving rack 43 is fixedly mounted on the bottom wall of one of the second clamping seats 312. The first driving rack 42 and the driving gear 41, as well as the second driving rack 43 and the driving gear 41, are meshed and drive each other. The length directions of both the first driving rack 42 and the second driving rack 43 are parallel to the length direction of the mounting plate 31. The driving cylinder 44 is mounted on the mounting plate 31, and the piston rod of the driving cylinder 44 is fixedly connected to one of the second clamping seats 312.

[0050] The implementation principle of Embodiment 1 of this application is as follows: After the hub bearing is processed in the front-end process, it is placed on the transfer table 1. The sliding plate 36 drives the mounting plate 31 to move closer to the transfer table 1, and then drives the first clamping seat 311 and the second clamping seat 312 to move closer to each other to clamp the flange of the hub bearing. Next, the lifting plate 34 is forced to rise to remove the hub bearing from the surface of the transfer table 1; then the mounting plate 31 can be driven to move along the conveying direction of the transfer table 1 to transfer the hub bearing to the riveting station 11 for riveting operation. The lifting plate 34 and the sliding plate 36 are designed so that the hub bearing does not contact the table surface of the transfer table 1 during the transfer process, reducing the possibility of scratches on the surface of the hub bearing during the transfer process.

[0051] Meanwhile, when the first clamping seat 311 and the second clamping seat 312 clamp the wheel hub bearing, the clamping arc surface 315 of the first clamping block 313 is adapted to the outer peripheral wall of the wheel hub bearing flange, which can play a positioning role for the wheel hub bearing and improve the accuracy of wheel hub bearing transfer.

[0052] Example 2: This application discloses a riveting device.

[0053] The difference between the riveting device disclosed in this application and Embodiment 1 is that:

[0054] Reference Figure 6 , Figure 7 In this embodiment, the flaw detection station 12 is fixedly installed with a mounting base 5. The mounting base 5 is equipped with a bottom plate 51 and a top plate 52 on the side wall near the mounting plate 31. The top plate 52 is located on top of the bottom plate 51. The upper surface of the bottom plate 51 is used to place the riveted wheel hub bearing. The first probe 13 is installed on the bottom wall of the top plate 52 (the first probe 13 is not shown in this embodiment). The mounting base 5 is provided with a flipping assembly 6 for flipping the wheel hub bearing.

[0055] The flipping assembly 6 includes a rotating disk 61, clamping bars 62, a second driving component, and a rotating component. A rotating shaft 612 is fixedly connected to the center of the rotating disk 61, and the rotating shaft 612 is rotatably mounted on the mounting base 5. The rotating disk 61 is rotatably mounted on the side wall of the mounting base 5 near the mounting plate 31 via the rotating shaft 612. Two sliding grooves 613 are formed on the surface of the rotating disk 61. Two clamping bars 62 are provided and corresponding to the two sliding grooves 613. One end of each clamping bar 62 is slidably mounted in the corresponding sliding groove 613. A return spring 622 is installed between each clamping bar 62 and the rotating disk 61. The return spring 622 normally forces the two clamping bars 62 to move away from each other.

[0056] Each clamping bar 62 has a second clamping block 623 fixedly installed at the end away from the rotating disk 61. The structure of the second clamping block 623 is the same as that of the first clamping block 313, and its structure will not be described in detail here. The specific structure of the second clamping block 623 is the same as that of the first clamping block 313. A second clamping area 621 for clamping the wheel hub bearing flange is formed between the second clamping blocks 623 of the two clamping bars 62.

[0057] Reference Figure 6 , Figure 8Each clamping bar 62 extends from one end away from the second clamping block 623 to the side of the rotating disk 61 near the mounting base 5. A second driving member is disposed on the mounting base 5 to drive the two clamping bars 62 to move closer to each other. In this embodiment, the second driving member includes a push block 63, a lead screw 64, and a motor 65. The side wall of the mounting base 5 near the rotating disk 61 is provided with a mounting groove 55. Both ends of the lead screw 64 are rotatably mounted in the mounting groove 55, and both ends of the lead screw 64 extend along the length direction of the transfer table 1. There are two push blocks 63, which are correspondingly arranged with the two clamping bars 62. Each push block 63 is connected to a connecting frame 631. The end of the connecting frame 631 away from the push block 63 extends into the mounting groove 55. The lead screw 64 passes through the connecting frames 631 of the two push blocks 63 in sequence. Both push blocks 63 are slidably mounted in the mounting groove 55 of the mounting base 5 through their respective connecting frames 631.

[0058] In this embodiment, the lead screw 64 and the connecting brackets 631 of the two push blocks 63 are both threaded (threads are not shown in the figure), and the threads between the lead screw 64 and the connecting brackets 631 of the two push blocks 63 are set to opposite directions (that is, when the lead screw 64 rotates, the two push blocks 63 can move closer to each other or further away from each other). The motor 65 is fixedly installed on the side wall of the mounting base 5, and the output shaft of the motor 65 extends into the mounting groove 55 and is coaxially connected to the lead screw 64. When the two push blocks 63 move closer to each other, the two push blocks 63 push their respective corresponding clamping bars 62 to reduce the second clamping area 621.

[0059] Reference Figure 8 Two limiting blocks 53 are fixedly installed on the side wall of the mounting base 5 near the rotating disk 61. Two insertion ports 531 are formed between the two limiting blocks 53. The two insertion ports 531 are correspondingly set with two pushing blocks 63. When the two clamping bars 62 clamp the wheel hub bearing, the pushing blocks 63 move into the corresponding insertion ports 531. In this embodiment, the shapes of the two limiting blocks 53 and the two pushing blocks 63 are all set to arc shape. When the two pushing blocks 63 are respectively inserted into the corresponding insertion ports 531, the two pushing blocks 63 and the two limiting blocks 53 combine to form a limiting ring surrounding the two clamping bars 62.

[0060] A rotating component is mounted on the mounting base 5 to drive the rotating shaft 612 of the rotating disk 61 to rotate. The rotating component can be a motor 65 or a rotary cylinder. In this embodiment, the rotating component is a rotary cylinder (not shown in the figure). The rotary cylinder is mounted on the mounting base 5, and the rotating end of the rotary cylinder is connected to the rotating shaft 612.

[0061] Reference Figure 6 , Figure 7It should be noted that in this embodiment, the bottom plate 51 and the top plate 52 are slidably installed on the side wall of the mounting base 5 near the rotating disk 61 so that they can be raised and lowered. The outer peripheral wall of the rotating disk 61 is provided with a guide ring groove 611. The side wall of the bottom plate 51 and the side wall of the top plate 52 are both fixedly connected with guide balls 54. The guide balls 54 of the bottom plate 51 and the guide balls 54 of the top plate 52 are slidably embedded in the guide ring groove 611.

[0062] The rotating disk 61 is elliptical and has a major axis and a minor axis (the major and minor axes of an ellipse are common knowledge and will not be elaborated on here, nor are they specifically marked in the figure). When the major axis of the rotating disk 61 rotates from the horizontal direction to the vertical direction, the bottom plate 51 and the top plate 52 move away from each other; when the major axis of the rotating disk 61 rotates from the vertical direction to the horizontal direction, the bottom plate 51 and the top plate 52 move closer to each other.

[0063] To improve the stability of the base plate 51, in other embodiments, a spring can be added between the base plate 51 and the mounting base 5. The spring provides support to the base plate 51, thereby reducing the weight borne by the guide ball 54 of the base plate 51 and reducing the possibility of structural deformation of the guide ball 54 of the base plate 51.

[0064] The implementation principle of Embodiment 2 of this application is as follows: After the hub bearing is transferred to the base plate 51 and the upper surface of the hub bearing is inspected by the first probe 13, the two push blocks 63 are driven to move closer to each other, so as to force the second clamping blocks 623 of the two clamping bars 62 to clamp and fix the hub bearing. Then, the rotating disk 61 is driven to rotate, so as to drive the hub bearing to flip over, so that the first probe 13 can inspect the lower surface of the hub bearing.

[0065] The guide ring groove 611 and guide ball 54 are arranged in series with the rotating disk 61, the bottom plate 51 and the top plate 52, so that when the long axis of the rotating disk 61 rotates from the horizontal direction to the vertical direction, the rotating disk 61 can force the bottom plate 51 and the top plate 52 to move away from each other, providing clearance space for the wheel hub bearing to be flipped, and reducing the possibility of interference between the wheel hub bearing and the bottom plate 51 during the flipping process.

[0066] During the rotation of the rotating disk 61, the two pushing blocks 63 and the two limiting blocks 53 combine to form a ring-shaped limiting ring. This allows the inner circumferential wall of the limiting ring to keep the two clamping bars 62 in place when the rotating disk 61 rotates. This ensures that the two clamping bars 62 maintain their clamping effect on the wheel hub bearing, reducing the possibility that the two clamping bars 62 may loosen and cause the wheel hub bearing to fall off when the rotating disk 61 rotates, and improving the overall flipping effect of the structure.

[0067] Example 3: This application discloses a riveting device.

[0068] The difference between the riveting device disclosed in this application and embodiment 2 is that:

[0069] Reference Figure 9 A side plate 7 is installed in the flaw detection station 12. The side plate 7 is located on one side of the base plate 51. A second probe (not shown in the figure) is installed on the side wall of the side plate 7 near the base plate 51. The second probe is used to detect flaws on the outer peripheral wall of the wheel hub bearing. The second probe is a vision camera.

[0070] In this embodiment, a rotating plate 8 is rotatably mounted on the upper surface of the base plate 51. A hub bearing is placed on the rotating plate 8 and is coaxial with the rotating plate 8. Two sliding strips 511 are slidably mounted on the upper surface of the base plate 51. The two sliding strips 511 are correspondingly arranged with two clamping strips 62. A pushing strip 512 is fixedly installed on the top wall of each sliding strip 511. The pushing strip 512 is arranged vertically. The upper end of the pushing strip 512 is used for the clamping strip 62 to push. When the two clamping strips 62 approach each other, the clamping strip 62 pushes the pushing strip 512 of the corresponding sliding strip 511 to force the corresponding sliding strip 511 to slide along its own length direction.

[0071] A linkage gear (not shown in the figure) is coaxially fixed to the outer peripheral wall of the rotating plate 8. A linkage rack (not shown in the figure) is fixed to the side wall of each sliding bar 511 near the rotating plate 8. The length direction of the linkage rack is consistent with the length direction of the sliding bar 511. The linkage racks of the two sliding bars 511 are meshed with the linkage gears so that when the two clamping bars 62 move closer or further away from each other, the rotating plate 8 can drive the hub bearing to rotate around its own central axis.

[0072] The implementation principle of Embodiment 3 of this application is as follows: After the wheel hub bearing is placed on the rotating plate 8 and the upper surface of the wheel hub bearing is inspected by the first probe 13, the two clamping bars 62 are driven to move closer to each other to clamp the wheel hub bearing. During the sliding process, the clamping bars 62 push the corresponding sliding bars 511, thereby forcing the rotating plate 8 to rotate so that the second probe can perform comprehensive inspection of the peripheral wall of the wheel hub bearing. After the clamping blocks of the two clamping bars 62 are clamped in the wheel hub bearing, the wheel hub bearing can be flipped over to facilitate the final inspection of the lower surface of the wheel hub bearing, thereby improving the comprehensiveness of the inspection of the wheel hub bearing.

[0073] Example 4: This application discloses a wheel hub bearing riveting device.

[0074] A wheel hub bearing riveting device includes a riveting worktable and a riveting device as described above, with a transfer table 1 fixedly installed on the upper surface of the riveting worktable.

[0075] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
