Description

Technical Field

[0001] This utility model relates to the field of wheel hub pickling technology, and more specifically, it relates to a wheel hub pickling and mounting robot. Background Technology

[0002] In the production of automobile wheels, after the wheel turning process is completed, the wheels need to be pickled to remove the oxide film on the surface of the wheels using an acidic cleaning agent. Most existing automobile wheel production workshops are intelligent workshops, and most processes are operated by robots. Robots are also used when pickling the wheels. The robots hang the wheels that need to be pickled and move the hung wheels into the acidic cleaning agent for cleaning.

[0003] However, during the pickling process of the wheel hub, because the robot hangs the wheel hub with corresponding hooks, the contact point between the wheel hub and the hooks cannot come into contact with the acid, resulting in the pickling of the area between the wheel hub and the hooks. This prevents the wheel hub from being fully pickled. In addition, during the pickling process, in order to ensure the cleaning effect of the wheel hub, the robot will move the hooks and the wheel hub inside the acid cleaning agent, causing the acid cleaning agent to flow on the surface of the wheel hub. During the movement, the wheel hub will shake and collide with the side wall of the cleaning tank, which can easily cause damage to the wheel hub. Utility Model Content

[0016] Compared with the prior art, this utility model provides a wheel hub pickling and mounting robot, which has the following beneficial effects:

[0017] 1.

After the wheel hub has been acid-washed for a period of time, the second drive mechanism drives the second gear ring and the second circular plate to rotate, causing the three second clamping plates to clamp the wheel hub with the three first clamping plates.

[0029] Please see Figures 1-5A wheel hub pickling and mounting robot includes a robot body 1, a connecting column 2 mounted on the robot body 1, a circular seat 3 fixedly connected to the connecting column 2, three first hanging rods 4 and three second hanging rods 5 evenly slidably arranged at the bottom end of the circular seat 3, six sliding grooves 20 provided at the bottom end of the circular seat 3, and sliding blocks 21 slidably arranged inside two of the sliding grooves 20. The bottom ends of the six sliding blocks 21 are respectively fixedly connected to the top ends of the three first hanging rods 4 and the three second hanging rods 5, so that the three first hanging rods 4 and the three second hanging rods 5 slide on the circular seat 3. Six fixing rods 22 are fixedly connected to the sliding blocks 21. Six fixed rods 22 are slidably engaged with six sliding blocks 21 to ensure stable sliding of the sliding blocks 21 within the sliding groove 20. Three first hanging rods 4 and three second hanging rods 5 are staggered. The bottom ends of the three first hanging rods 4 are all fixedly connected to a first clamping plate 6, and the bottom ends of the three second hanging rods 5 are all fixedly connected to a second clamping plate 7. A fixed post 8 is fixedly connected to the middle of the bottom end of the circular block 3. A first circular plate 9 and a second circular plate 10 are rotatably connected to the outside of the fixed post 8. A partition 23 is provided between the first circular plate 9 and the second circular plate 10 to separate them and ensure that the blocks are aligned. The first circular plate 9 serves as a support. A support plate 24 is fixedly connected to the bottom end of the fixed column 8. Multiple support columns 25 are arranged in a circular array at the top of the support plate 24. Each of the multiple support columns 25 is rotatably connected to a ball bearing 26. The top of each ball bearing 26 contacts the bottom end of the second circular plate 10, facilitating support for the second circular plate 10 and ensuring stable rotation of the first circular plate 9 and the second circular plate 10 on the fixed column 8. Each of the first circular plate 9 and the second circular plate 10 is provided with three guide grooves 11. The six guide grooves 11 are respectively slidably engaged with three first hanging rods 4 and three second hanging rods 5. A first toothed ring 12 and a second toothed ring 13 are fixedly connected to the outside of the first circular plate 9 and the second circular plate 10, respectively.

A through groove 27 is provided at the position corresponding to the three second hanging rods 5 on the first circular plate 9, and a through groove 27 is provided at the position corresponding to the three first hanging rods 4 on the second circular plate 10. During the rotation of the first circular plate 9, collisions with the three second hanging rods 5 and the three first hanging rods 4 are avoided.

[0030] Specifically, the first drive mechanism drives the first gear ring 12 and the first circular plate 9 to rotate, causing the three hanging rods to move the three first clamping plates 6 towards the side closer to the wheel hub, thus clamping the wheel hub with the three first clamping plates 6. After the wheel hub has been acid-washed for a period of time, the second drive mechanism drives the second gear ring 13 and the second circular plate 10 to rotate, causing the three second clamping plates 7 to clamp the wheel hub. Then, the first drive mechanism drives the first gear ring 12 and the first circular plate 9 to rotate in the opposite direction, causing the three first clamping plates 6 to separate from the wheel hub. This allows the contact points between the three first clamping plates 6 and the wheel hub to come into contact with the acidic cleaning agent, thus enabling acid washing of the contact points between the three first clamping plates 6 and the wheel hub, facilitating a comprehensive acid washing of the wheel hub. When mounting the wheel hub, the first drive mechanism drives the three first hanging rods. The three first clamping plates 6 and 4 move to clamp and fix the wheel hub, or the three second hanging rods 5 and three second clamping plates 7 move through the second drive mechanism to clamp and fix the wheel hub through the three second clamping plates 7. During the process of the robot body 1 moving the wheel hub inside the acidic cleaning agent, the wheel hub can be prevented from shaking, collision with the side wall of the cleaning tank, and manual damage to the wheel hub can be avoided. The first drive mechanism moves the three first hanging rods 4 and three first clamping plates 6, which facilitates the adjustment of the distance between the three first clamping plates 6. The second drive mechanism moves the three second hanging rods 5 and three second clamping plates 7, which facilitates the adjustment of the distance between the three second clamping plates 7. This makes it easy to clamp and fix wheel hubs of different models, improving its practicality.

The first gear 16 meshes with the first gear ring 12 to facilitate driving the first gear ring 12 and the first round plate 9 to rotate.

[0032] Specifically, the first motor 14 drives the gear to rotate, the first gear 16 drives the first gear ring 12 and the first circular plate 9 to rotate, and the rotation of the first circular plate 9 drives the first hanging rod 4 to move through the guide groove 11. At the same time, the first hanging rod 4 slides under the circular seat 3 to adjust the distance between the three first hanging rods 4, thereby adjusting the distance between the three first clamping plates 6.

[0033] Please see Figure 1 and Figure 2 The second drive mechanism includes a second motor 17. A second mounting base 18 is fixedly connected to the side end of the round base 3. The second motor 17 is mounted on the second mounting base 18. A second gear 19 is fixedly connected to the output end of the second motor 17. The second gear 19 meshes with the second gear ring 13 to facilitate driving the second gear ring 13 and the second round plate 10 to rotate.

[0034] Specifically, the second motor 17 drives the gear to rotate, the second gear 19 drives the second gear ring 13 and the second circular plate 10 to rotate, and the rotation of the second circular plate 10 drives the second hanging rod 5 to move through the guide groove 11. At the same time, the second hanging rod 5 slides under the circular seat 3 to adjust the distance between the three second hanging rods 5, thereby adjusting the distance between the three second clamping plates 7.

[0035] In summary, when using the overall equipment:

[0036] The first and second drive mechanisms respectively drive the first circular plate 9 and the second circular plate 10 to rotate, causing the three first clamping plates 6 and the three second clamping plates 7 to move to their outermost positions. Then, the robot body 1 moves the three first clamping plates 6 and the three second clamping plates 7 to the outside of the hub that needs to be acid-washed. Then, the first motor 14 drives the gear to rotate, and the first gear 16 drives the first gear ring 12 and the first circular plate 9 to rotate. The rotation of the first circular plate 9 drives the first hanging rod 4 to move through the guide groove 11, and at the same time, the first hanging rod 4 slides under the circular seat 3 to adjust the spacing between the three first hanging rods 4, so that the three first clamping plates 6 clamp and fix the hub. Then, the robot body 1 moves the hub into the cleaning tank containing acid cleaning agent, and the hub is acid-washed by the acid cleaning agent. During this process, the robot body 1 drives the wheel hub to shake and pickle inside the acidic cleaning agent. After pickling for a period of time, the second motor 17 drives the gear to rotate, the second gear 19 drives the second gear ring 13 and the second circular plate 10 to rotate. The rotation of the second circular plate 10 drives the second hanging rod 5 to move through the guide groove 11, and at the same time, the second hanging rod 5 slides under the circular seat 3 to adjust the distance between the three second hanging rods 5, so that the three second clamping plates 7 clamp the wheel hub. Then, the first motor 14 drives the gear to rotate in the opposite direction, the first gear 16 drives the first gear ring 12 and the first circular plate 9 to rotate. The rotation of the first circular plate 9 drives the first hanging rod 4 to move through the guide groove 11, and at the same time, the first hanging rod 4 slides under the circular seat 3 to separate the three first clamping plates 6 from the wheel hub. Then, the wheel hub continues to be pickled.
