Description

Technical Field

[0001] This utility model relates to the field of wheel hub spinning machine technology, specifically to a wheel hub spinning machine ejection structure. Background Technology

[0002] A wheel rim is a cylindrical metal component mounted on an axle that supports the tire from within its inner contour. It is also called a wheel rim, steel rim, wheel hub, or tire rim. Wheel rims come in many varieties depending on their diameter, width, molding method, and materials.

[0003] Currently, some existing wheel hub spinning machines use ejection structures that push the wheel hub out from the top of the spinning table by pressing the hub spokes from inside the hub. However, some wheel hub spokes are relatively narrow, resulting in a relatively small contact area between the ejection structure and the hub spokes. This can cause the surface of the hub spokes to deform due to relatively high pressure when the hub is ejected, leading to damage to the hub spokes, affecting product quality, and causing inconvenience in use. Therefore, we propose an ejection structure for wheel hub spinning machines to solve or improve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hub spinning machine ejection structure, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: it includes a hub spinning machine body, a bearing column fixed to the bottom of the inner surface of the hub spinning machine body, a second hydraulic rod fixed to the top of the hub spinning machine body, a clamping plate rotatably mounted on the top of the output shaft of the second hydraulic rod via a rotating shaft, a first drive motor fixed to the top of the bearing column, a spinning table fixed to the top of the output shaft of the first drive motor, and an ejection assembly disposed inside the bearing column.

[0006] Furthermore, the component includes a threaded rod rotatably mounted inside the support column via a bearing, a connector slidably mounted inside the support column, a second drive motor fixed to the inner surface of the support column via a mounting bracket, a first gear fixed to the top of the output shaft of the second drive motor, and a second gear fixed to the surface of the threaded rod, with the second gear meshing with the first gear.

[0007] Furthermore, the ejection assembly also includes a connecting bottom ring fixed to the surface of the connector, a buffer fixed to the top of the connecting bottom ring, a spring fixed to the top of the connecting bottom ring, and an ejection ring fixed to the top of the spring and the buffer.

[0008] Furthermore, a first hydraulic rod is fixed to the top of the hub spinning machine body, and a spinning component is fixed to the top of the output shaft of the first hydraulic rod.

[0009] Furthermore, two sets of first hydraulic rods are symmetrically fixed on the top of the hub spinning machine body, and the number of spinning components is the same as the number of first hydraulic rods.

[0010] Furthermore, a silicone cushioning pad is fixed to the top of the ejector ring.

[0011] Compared with the prior art, this utility model has the following advantages: By setting the ejection component, when it is necessary to eject the hub from the top side of the spinning table, the bottom of the hub can be pushed by the ejection component to eject the hub from the top side of the spinning table, without pushing the hub spokes. This avoids the problem that the contact area between the ejection structure and the hub spokes is relatively small due to the relatively narrow width of the hub spokes, which may cause the surface of the hub spokes to deform due to relatively large pressure when ejecting the hub, resulting in damage to the hub spokes. This improves product quality and is relatively convenient to use. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4The machine includes a hub spinning machine body 1. A first hydraulic rod 2 is fixed to the top of the hub spinning machine body 1. Two sets of the first hydraulic rod 2 are symmetrically fixed to the top of the hub spinning machine body 1. A spinning component 4 is fixed to the top of the output shaft of the first hydraulic rod 2. The first hydraulic rod 2 can drive the spinning component 4 fixed to the top of the output shaft to move. The number of spinning components 4 is the same as the number of first hydraulic rods 2. The spinning component 4 is existing technology known in the market and will not be described in detail here. A bearing column 11 is fixed to the bottom of the inner surface of the hub spinning machine body 1. The bearing column 11... The surface is provided with a sliding groove. The second hydraulic rod 3 is fixed to the top of the hub spinning machine body 1. The clamping plate 5 is rotatably mounted on the top of the output shaft of the second hydraulic rod 3 via a rotating shaft. The second hydraulic rod 3 can drive the clamping plate 5 fixed at the top of the output shaft to move. The clamping plate 5 is located between the two sets of spinning components 4 and on one side of the top of the support column 11. The first drive motor 12 is fixed to the top of the support column 11. The spinning table 6 is fixed to the top of the output shaft of the first drive motor 12. The first drive motor 12 can drive the spinning table 6 fixed at the top of the output shaft to rotate. The ejection assembly is set inside the support column 11.

[0019] The assembly includes a threaded rod 13 rotatably mounted inside a support column 11 via a bearing, and a connector 17 slidably mounted inside the support column 11. The threaded rod 13 passes through the interior of the connector 17 and is threadedly connected to it. The connector 17 is located inside a groove on the surface of the support column 11. A second drive motor 14 is fixed to the inner surface of the support column 11 via a mounting bracket. A first gear 15 is fixed to the top of the output shaft of the second drive motor 14. The second drive motor 14 can drive the first gear 15 fixed to the top of the output shaft to rotate. A second gear 16 is fixed to the surface of the threaded rod 13 and meshes with the first gear 15. When the first gear 15 rotates, it drives the meshing second gear 16 to rotate. When rotated, the fixed threaded rod 13 rotates, which in turn moves the threaded connector 17. The ejector assembly also includes a connecting bottom ring 8 fixed to the surface of the connector 17. When the connector 17 moves, it moves the fixed connecting bottom ring 8. A buffer 9 is fixed to the top of the connecting bottom ring 8; several sets of buffers 9 are fixedly arranged circumferentially on the top of the connecting bottom ring 8. The buffer 9 is existing technology and will not be described in detail here. A spring 10 is fixed to the top of the connecting bottom ring 8; several sets of springs 10 are fixedly arranged circumferentially on the top of the connecting bottom ring 8. When the connecting bottom ring 8 moves, it moves the fixed buffers 9 and springs 10. A limit rod is fixed to the top of the connecting bottom ring 8. A limiting rod is fitted onto the surface of the limiting rod, which restricts the position of the spring 10 to prevent it from bending when deformed. A push-out ring 7 is fixed to the top of the spring 10 and the buffer 9. One end of the limiting rod is inserted into the push-out ring 7 and slidably connected to it. When the connecting bottom ring 8 moves, causing the buffer 9 and spring 10 to move, the buffer 9 and spring 10 will move the top-fixed push-out ring 7. When the push-out ring 7 is obstructed, it will stop moving. At this time, the connecting bottom ring 8 will continue to move and compress the spring 10, causing it to deform and applying a certain force to the push-out ring 7. The greater the deformation of the spring 10, the greater the force applied by the spring 10 to the push-out ring 7, thus causing the push-out ring 7 to press against the bottom of the wheel hub. The applied force gradually increases and is relatively linear, thus avoiding the ejector ring 7 from applying a large force to the bottom of the hub at once, which would cause the hub to deform. When the ejector ring 7 can continue to move, the spring 10 can push the ejector ring 7 to move. The damper 9 can buffer the moving speed of the ejector ring 7, preventing the spring 10 from pushing the ejector ring 7 to move quickly, causing the hub pushed by the top of the ejector ring 7 to move too fast and detach from the top of the ejector ring 7. This prevents the hub from falling from the top side of the spinning table 6 and being damaged. It is relatively convenient to use. The top of the ejector ring 7 is fixed with a silicone buffer pad, which can buffer the contact between the ejector ring 7 and the surface of the hub, preventing the surface of the ejector ring 7 from directly contacting the surface of the hub and causing damage to the surface of the hub.

[0020] Working principle: When a wheel hub needs to be spun, the wheel hub to be spun is placed on top of the spinning table 6. The second hydraulic rod 3 then moves the clamping plate 5 closer to the top of the spinning table 6, thus clamping and fixing the wheel hub on top of the spinning table 6. The first drive motor 12 then rotates the spinning table 6, causing the wheel hub on top to rotate, and the wheel hub to rotate the clamping plate 5. The first hydraulic rod 2 then pushes the spinning component 4 to one side of the wheel hub to perform the spinning operation, completing the spinning process. After spinning, the second hydraulic rod 3 moves the clamping plate 5 in the opposite direction, moving it away from the spinning table 6. At this time, the second drive motor 14 drives the first gear 15 to rotate, which in turn drives the second gear 16 to rotate. The second gear 16 drives the threaded rod 13 to rotate. When the threaded rod 13 rotates, it drives the connecting piece 17 to move. When the connecting piece 17 moves, it drives the connecting bottom ring 8 to move. When the connecting bottom ring 8 moves, it drives the spring 10 and the buffer 9 to move. When the spring 10 and the buffer 9 move, they drive the ejection ring 7 to move. This causes the ejection ring 7 to move to the bottom of the hub and push the hub towards the top of the spinning table 6. This pushes the hub away from the surface of the spinning table 6 and moves it towards the top of the spinning table 6, thus ejecting the hub from the top of the spinning table 6. There is no need to push the hub spokes, which avoids the problem that the relatively narrow width of the hub spokes results in a relatively small contact area between the ejection structure and the hub spokes. This avoids the problem that the surface of the hub spokes may deform due to relatively large pressure when the ejection structure ejects the hub, resulting in damage to the hub spokes. This improves product quality and makes it more convenient to use.
