Description

Technical Field

[0001] This utility model relates to an automatic tire and wheel hub installation mechanism, belonging to the technical field of tire installation equipment. Background Technology

[0002] A wheel rim is a cylindrical metal component mounted on an axle, supporting the tire's inner contour. It's also called a wheel rim, steel rim, wheel, or rim wheel. A tire is a ring-shaped, elastic rubber product that rolls on the ground and is mounted on various vehicles or machinery. Tires are typically mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and guaranteeing vehicle performance. Both electric vehicles and automobiles require tires and wheel rims. The wheel rim provides rotation and support, while the tire withstands deformation, load, and extreme temperatures. Therefore, tires and wheel rims are essential components of a wheel. Currently, most tire and wheel rim assembly is done manually, a method that is labor-intensive and inefficient. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic tire and wheel hub installation mechanism with high installation efficiency.

[0004] To achieve this objective, the technical solution adopted by this utility model is: An automatic tire and wheel hub mounting mechanism includes a worktable and a frame located on the worktable. It also includes a wheel hub mold on the worktable, a drive motor, a first cylinder on the frame, and a tire-mounting roller connected to the first cylinder. A wheel hub is positioned on the wheel hub mold, and a tire is concentrically placed on the wheel hub. The wheel hub mold, the wheel hub, and the tire are rotated by the drive motor. The first cylinder drives the tire-mounting roller to move downwards. During the downward movement, the tire-mounting roller continuously compresses the rotating tire, causing the tire to be fitted onto the outside of the wheel hub.

[0005] As a further optimization of the above technical solution: the tire-loading roller is frustum-shaped, and the tire-loading roller includes a small-diameter end face, a large-diameter end face and an inclined side face. The large-diameter end face of the tire-loading roller is located close to the wheel hub, and the inclined side face of the tire-loading roller is in contact with the tire. When the tire-loading roller moves down and squeezes the tire, the inclined side face causes the tire to tilt under force.

[0006] As a further optimization of the above technical solution, it also includes a fixed shaft connected to the first cylinder and a tire pressing roller rotatably mounted on the fixed shaft via a bearing. The tire is tilted by the inclined side of the tire pressing roller, and the tire bead of the tire is tilted upward and tangent to the outer peripheral surface of the tire pressing roller. When the wheel hub bottom mold drives the wheel hub and the tire to rotate, the friction between the tire bead and the tire pressing roller causes the tire bead to drive the tire pressing roller to rotate relative to the fixed shaft.

[0007] As a further optimization of the above technical solution, it also includes a second cylinder located on the frame and a pressure block connected to the second cylinder. The second cylinder drives the pressure block to move down and contact the wheel hub and press the wheel hub. After the pressure block presses the wheel hub, the wheel hub begins to rotate.

[0008] As a further optimization of the above technical solution, it also includes a top tire cylinder located on the worktable and a top tire roller connected to the top tire cylinder. The top tire cylinder drives the top tire roller to move, so that the top tire roller presses against the side of the tire.

[0009] As a further optimization of the above technical solution: the inner side of the wheel hub end cover is provided with several protruding reinforcing ribs, the top of the wheel hub bottom mold is fixed with a positioning surface by screws, and several positioning grooves corresponding to the reinforcing ribs are provided on the positioning surface. When the wheel hub is placed on the wheel hub bottom mold, the reinforcing ribs enter the positioning grooves.

[0010] As a further optimization of the above technical solution: the top surface of the wheel hub bottom mold is provided with a positioning protrusion with the same diameter as the inner hole of the wheel hub, and both sides of the wheel hub are provided with multiple threaded holes for installing end caps. The wheel hub bottom mold is provided with multiple positioning holes corresponding to the threaded holes, and a positioning pin is placed in each positioning hole. When the wheel hub is placed on the wheel hub bottom mold, the positioning protrusion is engaged in the inner hole of the wheel hub, and the top surface of the positioning pin is inserted into the threaded hole.

[0011] As a further optimization of the above technical solution, it also includes a sliding plate and several guide posts, the guide posts passing through the sliding plate, and the two ends of the guide posts being fixed to the workbench and the top of the frame, respectively. The piston rod of the first cylinder is fixed to the sliding plate, and the tire loading roller and the fixed shaft are respectively connected to the sliding plate through connecting plates.

[0012] As a further optimization of the above technical solution, the workbench is also equipped with a lamp for illumination.

[0013] Compared with existing technologies, this utility model achieves automatic tire-rim installation by moving the tire-loading roller downwards and continuously squeezing the rotating tire, reducing manual intervention, increasing installation efficiency, and making the installation process simple, reliable, and labor-saving. The tire tilts due to the pressure of the tilted side of the tire-loading roller, and the tire bead tilts upwards and is tangent to the outer circumference of the tire-pressing roller. When the rim mold drives the rim and tire to rotate, the friction between the tire bead and the tire-pressing roller causes the tire bead to rotate relative to the fixed axis, thus avoiding direct contact between the tire bead and the rim during rotation and preventing scratches on the tire bead edge. The second cylinder drives the pressure block to move downwards and contact the rim, pressing the rim firmly. The pressure block prevents the rim from moving up and down during rotation. The top tire roller presses down on the side of the tire to assist in tire installation. The positioning between the rim and the rim mold is achieved by using the reinforcing ribs on the rim and the positioning grooves on the positioning surface, or by using a positioning protrusion inserted into the inner hole of the rim and the top of the positioning pin inserted into the threaded hole, ensuring that the rim rotates synchronously with the rim mold.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0018] like Figure 1-3 As shown, an automatic tire and wheel hub mounting mechanism includes a workbench 1 and a frame 11 located on the workbench 1. It also includes a wheel hub mold 2 located on the workbench 1, a drive motor, a first cylinder 6 located on the frame 11, and a tire-loading roller 5 connected to the first cylinder 6. A wheel hub 8 is positioned on the wheel hub mold 2, and a tire 9 is concentrically placed on the wheel hub 8. The wheel hub mold 2, the wheel hub 8, and the tire 9 are rotated by the drive motor. The first cylinder 6 drives the tire-loading roller 5 to move downwards. During the downward movement, the tire-loading roller 5 continuously compresses the rotating tire 9, thus installing the tire 9 onto the outside of the wheel hub 8. This achieves automatic installation of the tire 9 onto the wheel hub 8, reducing manual intervention, increasing installation efficiency, and making the installation process simple, reliable, and labor-saving. The tire 9 in this invention specifically refers to a vacuum-sealed run-flat tire, but it can also be applied to other types of tires.

[0019] In the above technical solution: the tire roller 5 is frustum shaped and includes a small diameter end face, a large diameter end face 51 and an inclined side face 52. The large diameter end face 51 of the tire roller 5 is located close to the wheel hub 8. The inclined side face 52 of the tire roller 5 is in contact with the tire 9. When the tire roller 5 moves down and squeezes the tire 9, the inclined side face 52 causes the tire 9 to tilt due to the force.

[0020] The above technical solution also includes a fixed shaft 41 connected to the first cylinder 6 and a tire pressure roller 4 rotatably mounted on the fixed shaft 41 via bearings. The tire 9 is tilted by the inclined side 52 of the tire roller 5, and the tire bead of the tire 9 is tilted upward and tangent to the outer peripheral surface of the tire pressure roller 4. When the wheel hub mold 2 drives the wheel hub 8 and the tire 9 to rotate, the friction between the tire bead and the tire pressure roller 4 causes the tire bead to drive the tire pressure roller 4 to rotate relative to the fixed shaft 41, thereby avoiding the tire bead from directly contacting the wheel hub 8 during rotation and causing the tire bead to be scratched, and avoiding damage to the edge of the tire bead.

[0021] The above technical solution also includes a second cylinder 7 located on the frame 11 and a pressure block 3 connected to the second cylinder 7. The second cylinder 7 drives the pressure block 3 to move down and contact the hub 8 and press the hub 8. After the pressure block 3 presses the hub 8, the hub 8 starts to rotate. The pressure block 3 prevents the hub 8 from moving up and down during rotation.

[0022] The above technical solution also includes a top tire cylinder 10 located on the workbench 1 and a top tire roller 12 connected to the top tire cylinder 10. The top tire cylinder 10 drives the top tire roller 12 to move, so that the top tire roller 12 presses against the side of the tire 9 to assist in the installation of the tire 9.

[0023] In the above technical solution: the inner side of the end cap of the wheel hub 8 is provided with several protruding reinforcing ribs 81, and the top of the wheel hub bottom mold 2 is fixed with a positioning surface 21 by screws. The positioning surface 21 is provided with several positioning grooves 22 corresponding to the reinforcing ribs 81. When the wheel hub 8 is placed on the wheel hub bottom mold 2, the reinforcing ribs 81 enter the positioning grooves 22 to position the wheel hub 8 and the wheel hub bottom mold 2, ensuring that the wheel hub 8 rotates synchronously with the wheel hub bottom mold 2. In this utility model, there are a total of 6 reinforcing ribs 81 on the end cap of the wheel hub 8. Therefore, the positioning surface 21 on the wheel hub bottom mold 2 is provided with six positioning grooves 22 corresponding to the screws. When the number and position of the reinforcing ribs 81 on the wheel hub 8 change, the screws are loosened to disassemble and replace the positioning surface 21, ensuring that the positioning grooves 22 on the positioning surface 21 correspond to the reinforcing ribs 81 on the wheel hub 8.

[0024] The above technical solution also includes a sliding plate 13 and several guide posts 14. The guide posts 14 are inserted through the sliding plate 13, and the two ends of the guide posts 14 are respectively fixed on the workbench 1 and the top of the frame 11. The piston rod of the first cylinder 6 is fixed to the sliding plate 13. The tire loading roller 5 and the fixed shaft 41 are respectively connected to the sliding plate 13 through the connecting plate.

[0025] In the above technical solution: the workbench 1 is also equipped with a lamp 15 for lighting.

[0026] The working process of this utility model is as follows: The wheel hub 8 is placed on the wheel hub base mold 2, so that the reinforcing rib 81 on the end cap of the wheel hub 8 is located in the positioning groove 22 of the positioning surface 21, thus positioning the wheel hub 8 on the wheel hub base mold 2; the tire 9 is placed on the wheel hub 8 in a centered position; the second cylinder 7 drives the pressure block 3 to move down and contact the wheel hub 8, pressing it firmly; then, the drive motor drives the wheel hub base mold 2, the wheel hub 8, and the tire 9 to rotate synchronously; the first cylinder 6 drives the tire-loading roller 5 to move down, and during the downward movement of the tire-loading roller 5, it continuously compresses the rotating tire 9. Tire 9 is tilted by the inclined side 52 of the tire mounting roller 5, and the tire bead of tire 9 is tilted upward and tangent to the outer circumference of the tire pressing roller 4, avoiding direct contact between the tire bead and the rim 8 during rotation and thus preventing scratches. The tire mounting roller 5 continues to move downward and press the tire 9 to install it between the tire 9 and the rim 8. During the above process, the tire-lifting cylinder 10 drives the tire-lifting roller 12 to move, so that the tire-lifting roller 12 presses down on the tire 9 to assist in the installation of the tire 9, until the tire 9 is completely fitted onto the outside of the rim 8, completing the installation of the tire 9. After the tire installation is completed, the tire-lifting cylinder 10 drives the tire-lifting roller 12 to move backward and reset, the first cylinder 6 drives the tire mounting roller 5 and the tire pressing roller 4 to move upward and reset, the second cylinder 7 drives the pressure block 3 to move upward and reset, the rim bottom mold 2 stops rotating, and the rim 8 moves upward to detach the rim 8 from the rim bottom mold 2. Example 2

[0027] This embodiment is largely similar to the previous embodiment in terms of technical solution. The differences will be described in detail, while the contents that are the same in both will not be repeated here.

[0028] The top surface of the wheel hub mold 2 is provided with a positioning protrusion with the same diameter as the inner hole of the wheel hub 8. Both sides of the wheel hub 8 are provided with multiple threaded holes 82 for installing end caps. The wheel hub mold 2 has multiple positioning holes corresponding to the threaded holes 82, and a positioning pin is placed in each positioning hole. When the wheel hub 8 is placed on the wheel hub mold 2, the positioning protrusion engages with the inner hole of the wheel hub 8, and the top of the positioning pin inserts into the threaded hole 82, completing the positioning between the wheel hub 8 and the wheel hub mold 2, ensuring that the wheel hub 8 rotates synchronously with the wheel hub mold 2.
