Description
Technical Field
[0001] This utility model relates to the field of wheel hub marking technology, specifically to an automatic marking device for automotive wheel hub unit assembly parameters. Background Technology
[0002] During the wheel hub manufacturing process, each wheel hub needs a unique identification number, similar to a person's ID number. This number serves two purposes: firstly, it facilitates wheel hub identification; secondly, it allows for tracing the wheel hub's production process when quality issues arise, enabling quick and easy identification of the root cause of the problem. Currently, most aluminum wheel hubs are marked manually, which is inefficient, has a high failure rate, and results in inconsistent marking positions, making it difficult to achieve unified tracking and management.
[0003] A search revealed a Chinese patent with publication number CN211942621U, which discloses a wheel hub marking device. The device uses a conveying mechanism to transport the measured wheel hub to a positioning mechanism for clamping, and then uses a marking mechanism to mark the measured positions, thereby ensuring more accurate marking positions. The positioning mechanism also facilitates rapid wheel hub positioning and improves marking efficiency.
[0004] The above solution uses clamping structures on both sides of the hub to fix the hub in the marking state. However, since there is no limiting structure in the direction of the hub's movement on the transmission roller, it is very easy for the hub to move too much on the transmission roller and move away from the clamping structure, causing the hub to be out of the correct marking position, thus affecting the marking quality of the hub.
[0005] Therefore, this utility model provides an automatic marking device for automotive wheel hub unit assembly parameters to solve the above problems. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, this utility model provides an automatic marking device for automotive wheel hub unit assembly parameters. This device solves the problem that, since there is no limiting structure in the direction of wheel hub movement on the transmission roller, the wheel hub is prone to move excessively on the transmission roller, causing it to move away from the clamping structure. This results in the wheel hub not being in the correct marking position, thus affecting the marking quality of the wheel hub.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] An automatic marking device for automotive wheel hub unit assembly parameters includes a conveyor frame, a conveyor roller, and a laser marking assembly. Two upright plates are fixedly connected to the conveyor frame, and a fixed plate is provided below the conveyor frame, with both ends of the fixed plate fixedly connected to the two upright plates respectively. A barrier bar and two clamping rods are provided above the fixed plate. The fixed plate is provided with a lifting assembly for raising and lowering the barrier bar and an adjusting assembly for adjusting the distance between the two clamping rods. The fixed plate is also provided with a drive assembly, which is kinetically connected to the lifting assembly and the adjusting assembly.
[0009] Preferably, the laser marking assembly includes a support frame fixedly connected to the conveyor frame, and a laser marking machine is mounted on the support frame.
[0010] Preferably, the lifting assembly includes a screw rotatably connected to a fixed plate, and the bottom end of the blocking bar is threadedly connected to the screw.
[0011] Preferably, a linkage block is fixedly connected to the barrier bar, a guide rod is slidably connected to the linkage block, and one end of the guide rod is fixedly connected to the fixing plate.
[0012] Preferably, the adjusting assembly includes two racks disposed on one side of the screw, each rack having a support fixedly connected to it, and the bottom ends of the two clamping rods being fixedly connected to the two support seats respectively.
[0013] Preferably, the fixing plate has two guide grooves, and a slider is slidably connected in each of the two guide grooves. The top ends of the two sliders are respectively fixedly connected to two racks.
[0014] Preferably, the drive assembly includes a motor fixedly connected to a fixed plate, the output shaft of the motor is equipped with a gear and a first pulley, the gear meshes with two racks, a second pulley is fixedly connected to the screw, and the second pulley is connected to the first pulley via a belt drive.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. By setting up a linkage structure between the blocking bar and the clamping bar, and using the motor-driven gear and pulley to synchronously control the lifting component and the distance adjustment component, the hub can be automatically blocked and clamped on the conveyor roller. After the blocking bar is raised, it can accurately limit the movement of the hub and avoid marking deviation caused by excessive conveying. At the same time, the clamping bar can quickly clamp the hub through rack and pinion transmission to ensure the stability of the hub during marking, significantly improving the uniformity and accuracy of the marking position, and solving the problems of low efficiency and high failure rate of manual operation.
[0017] 2. The synchronous movement of the barrier arm lifting and the clamping arm adjusting is achieved through a gear, rack, and pulley assembly, reducing manual intervention. The guide rod and slider structure enhance the stability of the barrier arm and rack movement, avoiding positioning deviations caused by mechanical vibration. This not only improves marking efficiency but also reduces the failure rate caused by human error, meeting the standardized management requirements of wheel hub mass production.

The laser marking assembly includes a support frame 4 fixedly connected to the conveyor frame 1, and a laser marking machine 5 is installed on the support frame 4.
[0025] The support frame 4 is located at the marking position of the wheel hub. The laser marking machine 5 is an existing structure that uses laser technology to mark the surface of the wheel hub.
[0026] Two upright plates 3 are fixedly connected to the conveyor frame 1. A fixed plate 6 is provided below the conveyor frame 1, and the two ends of the fixed plate 6 are fixedly connected to the two upright plates 3 respectively.

The fixed plate 6 is provided with a lifting component for raising and lowering the barrier bar 7 and an adjusting component for adjusting the distance between the two clamping rods 8.
[0027] In this embodiment, the lifting assembly includes a screw 12 rotatably connected to the fixed plate 6, and the bottom end of the barrier rod 7 is threadedly connected to the screw 12. The barrier rod 7 is raised and lowered by utilizing the threaded connection between the barrier rod 7 and the screw 12. When the barrier rod 7 is lowered, the hub can pass on the conveyor roller 2, and when the barrier rod 7 is raised, it can limit the hub on the conveyor roller 2.
[0028] The barrier arm 7 is fixedly connected to a linkage block 14, and a guide rod 15 is slidably connected to the linkage block 14. One end of the guide rod 15 is fixedly connected to the fixed plate 6. The linkage block 14 slides on the guide rod 15 to guide the barrier arm 7 to move up and down.
[0029] In this embodiment, the pitch adjustment assembly includes two racks 18 disposed on one side of the screw 12. Each rack 18 is fixedly connected to a support seat 19. The bottom ends of the two clamping rods 8 are respectively fixedly connected to the two support seats 19. When the racks 18 move, the support seats 19 will drive the clamping rods 8 to move synchronously.
[0030] Two guide grooves 16 are provided on the fixed plate 6. A slider 17 is slidably connected in each of the two guide grooves 16. The top of the two sliders 17 is fixedly connected to two racks 18 respectively. The racks 18 drive the sliders 17 to slide in the guide grooves 16 to improve the stability of the racks 18 during movement.
[0031] The fixed plate 6 is also equipped with a drive assembly, which is connected to the lifting assembly and the adjusting assembly. The drive assembly includes a motor 9 fixedly connected to the fixed plate 6. The output shaft of the motor 9 is equipped with a gear 10 and a first pulley 11. The gear 10 meshes with two racks 18.

[0032] The output shaft of motor 9 drives the second pulley 13 to rotate, and the second pulley 13 drives the screw 12 to rotate synchronously through the transmission connection between the first pulley 11 and the second pulley 13. At this time, the output shaft of motor 9 also drives the gear 10 to rotate, and causes the two racks 18 to move towards each other. That is, the two racks 18 drive the clamping rod 8 to move through the support seat 19 to complete the clamping and positioning of the hub. At the same time, the blocking rod 7 moves upward and moves the top of the blocking rod 7 above the conveyor roller 2 to block the hub.
