[0002] Tire bolt assembly is an important assembly process in wheel hub unit production lines. Bolt feeding is a key step in the assembly of automotive wheel hub units. Optimizing the bolt feeding mechanism to make feeding more convenient and faster, and improving wheel hub unit production efficiency and pass rate, is the goal pursued by the wheel hub unit assembly equipment manufacturing industry.

[0003] Chinese patent CN220761572U discloses a bolt feeding device that can accurately position bolts by setting positioning blocks and positioning grooves, and can also effectively prevent bolts from moving. This allows the clamping mechanism to clamp bolts more accurately and quickly, thereby enabling faster connection to the next process and improving the production efficiency of subsequent processes.

[0004] Although the above solution can clamp and move the bolts arranged on the vibratory feeding plate through the clamping mechanism, there are many types of tire bolts due to differences in length, thread specifications, and surface treatment. The vibratory feeding plate only has the function of arranging bolts, which can easily lead to bolts of different sizes in the unloading position, affecting the installation quality of the wheel hub unit.

[0005] Therefore, this utility model provides a bolt feeding device for wheel hub units to solve the above problems. Utility Model Content

[0022] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0023] A bolt feeding device for a wheel hub unit includes a base plate 1 and a vibrating unloading platform 2. The output end of the vibrating unloading platform 2 is fixedly connected to a feeding plate 3. The vibrating unloading platform 2 is an existing structure that uses a combination of rotation and vibration to arrange the bolts. The feeding plate 3 has a moving groove 4, which transports the arranged bolts in an inverted manner in the moving groove 4, that is, the bolt head is above the feeding plate 3, while the bolt shank is in the moving groove 4.

[0024] The feeding plate 3 is fixedly connected to a fixing ring 5, which is located at the feeding end of the feeding plate 3. The fixing ring 5 has a feeding port 6, which has a certain angle with the connection between the feeding port 6 and the connection between the feeding plate 3 and the fixing ring 5. The base plate 1 is rotatably connected to a support pipe 7, and a conveying plate 8 is fixedly connected to the support pipe 7. The conveying plate 8 is located inside the fixing ring 5. The conveying plate 8 has a material groove 9 arranged in a circular array. When the support pipe 7 rotates, it will position the material groove 9 at the connection between the feeding plate 3 and the fixing ring 5, thereby connecting the moving groove 4 and the material groove 9. The bolts arranged in the moving groove 4 are then transported into the material groove 9. The bolts are fed by rotating the conveying plate 8.

[0025] In this embodiment, a feeding assembly is provided inside the support tube 7. The feeding assembly includes a fixing plate 10 fixedly connected to the base plate 1, an electric push rod 11 fixedly connected to the fixing plate 10, and a feeding push plate 12 fixedly connected to the telescopic end of the electric push rod 11.

[0026] When the conveying plate 8 rotates the bolts via the material trough 9, the bolts are directly conveyed to the discharge port 6. The output shaft of the electric push rod 11 drives the discharge push plate 12 to move, and the unqualified bolts in the material trough 9 are discharged through the discharge port 6.

[0027] A CCD detector 18 is provided on one side of the fixed ring 5. A fixed frame 19 is fixedly connected to the base plate 1. An adjusting bolt 20 is rotatably connected to the fixed frame 19. A mounting seat 21 is threadedly connected to the adjusting bolt 20. The CCD detector 18 is mounted on the mounting seat 21. A guide rod 22 is fixedly connected inside the fixed frame 19. One end of the mounting seat 21 is slidably connected to the guide rod 22.

[0028] By rotating the adjusting bolt 20, the mounting base 21 moves on the adjusting bolt 20 via the guide rod 22, thereby moving the CCD detector 18 to the detection position. The CCD detector 18 takes pictures of the bolts in the material trough 9 and judges the appearance and length of the bolts. Suitable bolts are transported to the loading position, while unqualified bolts are transported to the unloading position for unloading.

[0029] The base plate 1 is equipped with a drive assembly for rotating the support tube 7, and the support tube 7 drives the transport plate 8 to rotate to complete the loading and unloading of bolts.

[0030] In this embodiment, the drive assembly includes a motor 15 mounted on the base plate 1, a first pulley 16 mounted on the output shaft of the motor 15, a second pulley 17 fixedly connected to the support tube 7, and the second pulley 17 being drively connected to the first pulley 16.

[0031] The four material slots 9 on the conveying plate 8 correspond to the loading position, detection position, feeding position and unloading position in sequence. The output shaft of the motor 15 drives the first pulley 16 to rotate. Under the transmission action of the first pulley 16 and the second pulley 17, the second pulley 17 drives the support tube 7 to rotate 90 degrees counterclockwise. This can move the bolt at the loading position to the detection position for detection. If the detection is qualified, it will rotate another 90 degrees and be fixed for feeding. If the detection is unqualified, it will rotate another 90 degrees and then rotate another 90 degrees to move the bolt to the unloading position for feeding.

[0032] In this embodiment, a support 13 is fixedly connected to the base plate 1, and a collection box 14 is placed on the support 13. The collection box 14 is located below the discharge port 6. The unqualified bolts discharged from the discharge position can be collected through the collection box 14.
