Description

Technical Field

[0001] This invention belongs to the field of assembly tooling technology, and specifically relates to a wheel hub mounting tooling. Background Technology

[0002] Spoked wheels typically refer to a wheel structure consisting of a central hub, radially arranged spokes, and an outer rim. Dozens of thin spokes "pull" the rim to the hub through tension, rather than relying on the rigidity of the material itself. Compared to a one-piece wheel, it is lighter in weight for the same strength. The elasticity of the spokes can absorb minor vibrations from the road surface. If the rim wobbles or a spoke breaks, it can be repaired by adjusting the tension or replacing the individual spoke, without having to replace the entire wheel. However, existing spoke installations rely on manual loading and fastening with fasteners. This manual approach affects the tightness of the fastening, resulting in inconsistent spoke tightness and making it difficult to achieve uniformity in factory-produced products. Therefore, obtaining wheel hub installation fixtures is crucial. Summary of the Invention

Several wedge-shaped protrusions are fixed on the inner ring, with a first inner ring hole and a second inner ring hole on each side of the wedge-shaped protrusions.

[0004] The hub fixing assembly includes a base and a concentrically arranged disk and ring rotatably connected to the base. The base is fixed with a plurality of first slide rails and a plurality of second slide rails. The disk has a plurality of first guide rails, and the ring has a plurality of second guide rails. A first protrusion cooperating with the first guide rail is fixed on a first slider sliding on the first slide rail, and a second protrusion cooperating with the second guide rail is fixed on a second slider sliding on the second slide rail. The assembly also includes a base, which is rotatably connected to the base. A third tooth is formed on the outer wall of the base, and a third motor is fixed on the base. The output shaft of the third motor is fixed with a third gear meshing with the third tooth.

[0005] The inner walls of the first and second protrusions are connected by several springs to positioning pins; and / or, the inner wall of the second protrusion has an outward arc-shaped protrusion; and / or, several of the first protrusions are joined together to form a cone, the outer wall of the cone being stepped; or joined together to form a circular triangle, the outer wall of the circular triangle having a certain curvature and a certain strength, which can achieve a stable expansion force.

[0006] One method includes a connector and a first lifting cylinder. The fastening assembly and the spoke limiting assembly are installed on the connector so that the fastening assembly and the spoke limiting assembly are located on the outer side of the outer ring and the inner side of the inner ring of the hub. The connector is fixed on the first lifting cylinder. The first lifting cylinder drives the fastening assembly and the spoke limiting assembly to leave or enter the spoke installation and fastening station. It also includes a spoke pre-installation station and a fastener pre-installation station, which are the processes preceding the spoke installation and fastening stations. A first three-axis robotic arm and a second three-axis robotic arm are fixed on the base. A gripping cylinder is fixed to the end of the first three-axis robotic arm. The gripping cylinder grips the spokes and inserts them into the first inner ring hole of the inner ring and the first outer ring hole of the outer ring. A first guide block is fixedly connected to the base between the disc and the ring through a second lifting cylinder. A first guide channel is opened on the first guide block to adapt to the first angle spokes between the first inner ring hole and the first outer ring hole. The second three-axis robotic arm installs the fasteners onto the first angle spokes that pass through the first outer ring hole. A second guide block is fixedly connected to the base between the disc and the ring via a third lifting cylinder. A second guide channel is opened on the second guide block to adapt to the second angle spoke between the second inner ring hole and the second outer ring hole. The second three-axis robotic arm installs the fastener onto the second angle spoke that passes through the second outer ring hole.

[0007] The outer end of the connector is fixed to the vertically arranged first connector by the first vertical cylinder. The fastening assembly includes a rotary motor and a locking screw head fixedly connected to the output shaft of the rotary motor. A first horizontal cylinder is fixed on the first connector. A first vertical plate is fixed on the output end of the first horizontal cylinder. The rotary motor is rotatably connected to the first vertical plate. A second horizontal cylinder is fixed on the first vertical plate. The output end of the second horizontal cylinder is rotatably connected to the outer wall of the rotary motor. The inner end of the connector is fixed to the vertically arranged second connector by the second vertical cylinder. A third horizontal cylinder is fixed on the second connector. The output end of the third horizontal cylinder is fixedly connected to the second vertical plate. The spoke limiting assembly includes a limiting plate rotatably connected to the second vertical plate. A fourth horizontal cylinder is fixed on the second vertical plate.

[0008] It also includes a bracket, the first lifting cylinder is fixed on the bracket, a steering cylinder is fixed to the output end of the first lifting cylinder, and the output end of the steering cylinder is fixedly connected to the connecting member.

[0009] The second method also includes a longitudinal lifting cylinder, which is fixed to the lower end of the base. It also includes a fixed vertical bracket with several fastening components spirally distributed on the vertical bracket. The first fastening component adapted to the first angle spoke and the second fastening component adapted to the second angle spoke are arranged at intervals. The longitudinal lifting cylinder extends out of the vertical bracket. After the first three-axis robotic arm and the second three-axis robotic arm complete the pre-installation of the spokes and fasteners, the longitudinal lifting cylinder descends and the base rotates intermittently to realize the spiral descent of the hub fixing component, so as to realize the fastening installation of the fasteners.

[0010] This invention has a simple structure. Through the linkage of mechanical structures, it can realize the automatic feeding of spokes and the operation of limiting and locking fasteners, which can improve production efficiency, ensure assembly accuracy, reduce reliance on manual labor and labor intensity, and adapt to the needs of modern large-scale manufacturing.

[0011] Traditional manual spoke installation is time-consuming, inefficient, and makes it difficult to ensure that the installation angle, tension, and position of each spoke are completely consistent. Using a three-axis robotic arm for feeding enables precise spoke positioning and continuous feeding, significantly reducing assembly time per unit while ensuring consistency across batches of products.

[0012] Manual labor is not only physically demanding, but also carries the risk of workplace injuries due to repetitive movements. Automated systems can replace manual labor in highly repetitive and precise assembly tasks, reducing reliance on skilled workers.

[0013] Modern wheel hubs are becoming increasingly complex, demanding extremely high assembly precision. This invention can ensure that each spoke is subjected to uniform force by preset control parameters such as spoke insertion angle and tightening torque, thus avoiding wheel rim wobble or spoke breakage caused by human error.

[0018] The inner walls of the first protrusion 108 and the second protrusion 110 are connected to positioning pins 119 by a plurality of springs 118; and / or, the inner wall of the second protrusion 110 is provided with an outward arc protrusion; and / or, a plurality of the first protrusions 108 are joined together to form a cone, the outer wall of the cone being stepped; or joined together to form a round triangle, the outer wall of the round triangle having a certain curvature and a certain strength, capable of achieving stable expansion force.

[0019] One method includes a connector 201 and a first lifting cylinder 202. The fastening component 3 and the spoke limiting component 2 are installed on the connector 201 so that the fastening component 3 and the spoke limiting component 2 are located outside the outer ring 602 and inside the inner ring 601 of the hub 6. The connector 201 is fixed on the first lifting cylinder 202. The first lifting cylinder 202 drives the fastening component 3 and the spoke limiting component 2 to leave or enter the spoke installation and fastening position. It also includes a spoke pre-installation station and a fastener pre-installation station, which are the processes preceding the spoke installation and fastening stations. A first three-axis robotic arm and a second three-axis robotic arm are fixed on the base 111. A gripping cylinder is fixed to the end of the first three-axis robotic arm. The gripping cylinder grips the spoke and inserts it into the first inner ring hole of the inner ring and the first outer ring hole of the outer ring 602. A first guide block 203 is fixedly connected to the base 111 between the disc 101 and the ring 102 through a second lifting cylinder. A first guide channel is opened on the first guide block 203 to adapt to the first angle spoke 603 between the first inner ring hole and the first outer hole. The second three-axis robotic arm installs the fastener onto the first angle spoke 603 that passes through the first outer ring hole. A second guide block 204 is fixedly connected to the base 111 between the disc 101 and the ring 102 via a third lifting cylinder. The second guide block 204 has a second guide channel to accommodate the second angle spoke 604 between the second inner ring hole and the second outer ring hole. The second three-axis robotic arm installs fasteners onto the second angle spoke 604 that passes through the second outer ring hole. The diameter of the inner ring hole decreases sequentially from the center to the outside, and the diameter of the outer ring hole decreases sequentially from the outside to the center to facilitate spoke insertion.

[0020] Since there are spokes with two angles on both sides of the hub 6, spokes with the first angle are inserted between the first inner ring hole and the first outer ring hole, and spokes with the second angle are inserted between the second inner ring hole and the second outer ring hole.

[0021] The outer end of the connector 201 is fixed to the vertically arranged first connector 206 by the first vertical cylinder 205. The fastening assembly 3 includes a rotary motor 304 and a locking screw head 301 fixedly connected to the output shaft of the rotary motor 304. A first horizontal cylinder 302 is fixed on the first connector 206. A first vertical plate 303 is fixed on the output end of the first horizontal cylinder 302. The rotary motor 304 is rotatably connected to the first vertical plate 303. A second horizontal cylinder 207 is fixed on the first vertical plate 303. The output end of the second horizontal cylinder 207 is rotatably connected to the rotary motor 304. The outer wall of the rotating motor 304; the inner end of the connector 201 is fixed by the second vertical cylinder to the vertically arranged second connector 209, the second connector 209 is fixed with a third horizontal cylinder 210, the output end of the third horizontal cylinder 210 is fixedly connected to the second vertical plate 211, the spoke limiting assembly 2 includes a limiting plate 212 rotatably connected to the second vertical plate 211, the second vertical plate 211 is fixed with a fourth horizontal cylinder 213, the output head of the fourth horizontal cylinder 213 is rotatably connected to the limiting plate 212, and the limiting plate 212 is provided with a limiting protrusion to block the inner ring hole.

[0022] It also includes a bracket 214, the first lifting cylinder 202 is fixed on the bracket 214, the output end of the first lifting cylinder 202 is fixed with a steering cylinder 215, and the output end of the steering cylinder 215 is fixedly connected to the connector 201.

[0023] When put into use, the first guide block 203 rises, then the first three-axis robotic arm passes through the first angle spoke 603, the second three-axis robotic arm installs the fasteners, the hub 6 fixing component 1 rotates intermittently by a certain angle, then the first lifting cylinder 202 drives the connecting piece 201 to descend, the first transverse cylinder 302 and the third transverse cylinder 210 extend to achieve limit and screw locking movement. At this time, the first three-axis robotic arm still passes through the next first angle spoke 603, then the connecting piece 201 rises, the hub 6 fixing component 1 rotates intermittently by a certain angle, and after the first angle spoke 603 and fasteners have completed one round of loading, the work stops, but the connecting piece 201 will control the screw locking head 301 to tighten the first few fasteners again to increase installation stability.

[0024] After the first angle spoke 603 is installed, the steering cylinder 215 turns the spoke. Then the second lateral cylinder 207 and the fourth lateral cylinder 213 work to convert the angle of the spoke limiting component 2 and the fixing component. Then the first guide block 203 descends and the second guide block 204 rises. The entire device is converted to the installation angle of the second angle spoke 604. The above operation can then be performed.

[0025] After the spokes on one side are installed, the hub 6 is flipped over to install the spokes on the other side.

[0026] The second method also includes a longitudinal lifting cylinder 501, which is fixed to the lower end of the base 401. It also includes a fixed vertical support 502, on which several fastening components 3 are spirally distributed. The first fastening component 3 adapted to the first angle spoke 603 and the second fastening component 3 adapted to the second angle spoke 604 are spaced apart. The longitudinal lifting cylinder 501 extends out of the vertical support 502. After the first and second three-axis robotic arms complete the pre-installation of the spokes and fasteners, the longitudinal lifting cylinder 501 descends, and the base 111 rotates intermittently, realizing the spiral descent of the hub 6 fixing component 1 to achieve the fastening installation of the fasteners. In this method, a magnetic structure can be fixed to the inner ring 601. The protruding part at the end of the spoke can be attracted by the magnetic structure, thus enabling pre-installation. The cross-section of the protruding part at the end is hexagonal, preventing rotation when the fasteners are locked.

[0027] This invention has a simple structure. Through the linkage of mechanical structures, it can realize the automatic feeding of spokes and the operation of limiting and locking fasteners, which can improve production efficiency, ensure assembly accuracy, reduce reliance on manual labor and labor intensity, and adapt to the needs of modern large-scale manufacturing.

[0028] Traditional manual spoke installation is time-consuming, inefficient, and makes it difficult to ensure that the installation angle, tension, and position of each spoke are completely consistent. Using a three-axis robotic arm for feeding enables precise spoke positioning and continuous feeding, significantly reducing assembly time per unit while ensuring consistency across batches of products.

[0029] Manual labor is not only physically demanding, but also carries the risk of workplace injuries due to repetitive movements. Automated systems can replace manual labor in highly repetitive and precise assembly tasks, reducing reliance on skilled workers.

[0030] Modern wheel hubs have increasingly complex structures, requiring extremely high assembly precision. This invention can ensure that each spoke is subjected to uniform force by preset control parameters such as spoke insertion angle and tightening torque, thus avoiding wheel rim wobble or spoke breakage caused by human error.

[0031] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
