Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and provides a tooling for installing wheels. Background Technology

[0002] Some rail vehicles use rubber-tired wheels. The installation of rubber-tired wheels differs fundamentally from the installation of traditional bogie wheelsets. Rubber-tired urban rail vehicles lack track positioning, requiring higher positioning accuracy and more integrated assembly. A central hole is located on the rubber wheel for mounting on the axle. A ring of fastening holes surrounds the central hole, with corresponding holes on the axle. When installing the rubber wheel onto the axle, its position needs to be adjusted to align the holes on the rubber wheel with those on the axle, and then secured with bolts.

[0003] Currently, when installing rubber wheels, a mounting fixture is required for support to adjust their position in the vertical plane. However, during actual operation, it was found that although the holes of the rubber wheel are aligned with those of the axle, the stability of the rubber wheel on the mounting fixture is poor. The rubber wheel inevitably tilts, causing the axis of the rubber wheel's shaft hole to not coincide with the axis of the axle's mounting shaft, resulting in an angle between them and poor alignment. When pushing the rubber wheel onto the axle to fit its shaft hole onto the axle's mounting shaft, the misalignment of the axes makes installation difficult, requiring repeated manual adjustments to the tilt angle of the rubber wheel. Otherwise, scratches or dents may be created on the surface of the shaft hole or mounting shaft, affecting the fit accuracy between the rubber wheel and the axle.

[0004] Therefore, how to solve the problem of poor alignment between the shaft hole of the rubber wheel and the mounting shaft of the axle when installing the rubber wheel in related technologies has become an important technical problem to be solved by those skilled in the art.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] The following is combined with Figures 1 to 2 This invention describes a tooling for installing wheels.

[0023] like Figures 1 to 2 As shown, the wheel installation fixture provided in this embodiment of the present invention includes a body 1, a support device, a tilt adjustment device, and a position adjustment device.

[0024] Specifically, the fuselage 1 serves as a support, and the support device, tilt adjustment device, and position adjustment device are all located on the fuselage 1. The fuselage 1 has lateral, longitudinal, and vertical dimensions; the lateral dimension of the fuselage 1 is as follows: Figure 1 The direction indicated by x in the middle, the longitudinal direction of body 1 is as follows: Figure 1 The direction indicated by y in the middle, the vertical direction of body 1 is as follows Figure 1 The direction indicated by z. Among the transverse, longitudinal, and vertical directions of body 1, any two are perpendicular to each other.

[0025] The support device includes a mounting base 2 and a pair of support arms 3.

[0026] Mounting base 2 is provided on body 1, and a pair of support arms 3 are provided on mounting base 2. The axis of the pair of support arms 3 is arranged along the longitudinal direction of body 1, and the pair of support arms 3 are distributed at intervals along the transverse direction of body 1. The wheel is placed upright on the pair of support arms 3, and the circumferential side of the wheel abuts against the pair of support arms 3.

[0027] A tilt adjustment device is installed on the mounting base 2 and is used to adjust the angle between the wheel and the reference surface, which is perpendicular to the vertical direction of the machine body 1. By adjusting the angle between the wheel and the reference surface, the tilt angle of the wheel can be adjusted, thereby adjusting the angle between the wheel axis and the axle axis.

[0028] The position adjustment device is capable of adjusting the position of the mounting base 2 at least in the lateral and vertical directions of the body 1 to adjust the position of the wheels.

[0029] When installing the wheel onto the axle, the wheel is placed upright on a pair of support arms 3. The position of the mounting base 2 is adjusted by the position adjustment device according to the position of the axle and the position of each hole on the axle, so that the wheel axle hole is aligned with the mounting shaft of the axle.

[0030] Then, based on the axle axis direction, the tilt angle of the wheels is adjusted using the tilt adjustment device to make the wheel axis coincide with the axle axis.

[0031] Then, move the body 1 longitudinally, or adjust the position of the mounting base 2 longitudinally along the body 1 using the position adjustment device, so that the wheel is close to the axle and mounted on the axle. Finally, tighten the connection.

[0032] With this configuration, when installing rubber wheels on the axle of a rail vehicle, the rubber wheels serve as the aforementioned wheels. During the installation process, the tilt adjustment device can adjust the tilt angle of the rubber wheels, ensuring that the axis of the rubber wheels coincides with the axis of the axle. This ensures the alignment of the rubber wheels and the axle, thereby solving the problem of poor alignment between the shaft hole of the rubber wheels and the mounting shaft of the axle in related technologies.

[0033] Furthermore, during the process of fastening the rubber wheel to the axle with bolts, the wheel mounting fixture in this embodiment supports the rubber wheel, corrects the dynamic balance of the rubber wheel, maintains the alignment of each hole of the rubber wheel with each hole of the axle, and ensures that parameters such as the torque of the fastening bolts and the balance of the rubber wheel meet the standards.

[0034] The following descriptions all use rubber tires as wheels and are installed on the axles of rail vehicles.

[0035] In this embodiment of the invention, the tilt adjustment device includes a stop mechanism and a contact mechanism.

[0036] The stop mechanism is located between a pair of support arms 3. The end of the rubber wheel near the support arm 3 interacts with the stop mechanism. The stop mechanism can restrict the longitudinal movement of the end of the rubber wheel near the support arm 3 along the body 1, so as to prevent the rubber wheel from sliding off the pair of support arms 3 along the longitudinal direction of the body 1.

[0037] The abutting mechanism is located above the stop mechanism. The abutting mechanism abuts against the end of the rubber wheel furthest from the support arm 3, and also against the side of the rubber wheel closest to the machine body 1. The abutting mechanism includes an abutting member 4, which can reciprocate longitudinally along the machine body 1. By adjusting the position of the abutting member 4 along the longitudinal direction of the machine body 1, the position of the end of the rubber wheel furthest from the support arm 3 along the longitudinal direction of the machine body 1 can be adjusted, thereby adjusting the tilt angle of the rubber wheel.

[0038] In this embodiment, the abutment mechanism also includes a support rod 5 and an adjusting rod 6.

[0039] The axis of the support rod 5 is arranged vertically along the body 1, and the first end of the support rod 5 is connected to the mounting base 2. The axis of the adjusting rod 6 is arranged longitudinally along the body 1, and the adjusting rod 6 is located at the second end of the support rod 5, and the position of the adjusting rod 6 along the longitudinal direction of the body 1 is adjustable. The abutment 4 is located at the end of the adjusting rod 6 away from the body 1.

[0040] The support rod 5 serves as a support, ensuring that the abutment 4 and the stop mechanism have a certain height difference along the vertical direction of the body 1. The position of the abutment 4 can be adjusted by adjusting the position of the adjusting rod 6 relative to the support rod 5.

[0041] Specifically, an internal thread is provided at the second end of the support rod 5, with the axis of the internal thread oriented longitudinally along the machine body 1. An external thread is provided on the adjusting rod 6, which is adapted to the internal thread to allow the adjusting rod 6 to be threadedly connected to the second end of the support rod 5. By turning the adjusting rod 6, the abutment 4 can be displaced longitudinally along the machine body 1.

[0042] In a specific embodiment, the abutting member 4 includes an abutting plate, which is rotatably disposed at the end of the adjusting rod 6. The side of the abutting plate away from the adjusting rod 6 is the abutting surface, used to abut against the rubber wheel.

[0043] The abutment plate's rotation axis relative to the adjusting rod 6 is at least along the transverse direction of the machine body 1, allowing the angle of the abutment plate relative to the reference surface to be adjusted. This allows the tilt angle of the abutment plate to match the tilt angle of the rubber wheel, ensuring contact between the abutment plate and the rubber wheel surface, increasing the contact area between the abutment plate and the rubber wheel, and providing stability to the rubber wheel.

[0044] Specifically, during the rotation of the abutment plate relative to the adjusting rod 6, the included angle between the abutment plate and the reference surface is controlled to be at least within the range of 67° to 113°.

[0045] In some embodiments, the abutment plate is connected to the end of the adjusting rod 6 by a universal connector, so that the abutment plate can rotate universally relative to the adjusting rod 6, thereby improving the flexibility and adaptability of the abutment plate.

[0046] In this embodiment of the utility model, the stopping mechanism includes a first stopping member 7 and a second stopping member 8. Both the first stopping member 7 and the second stopping member 8 are disposed on the mounting base 2, and the second stopping member 8 is located on the side of the first stopping member 7 away from the mounting base 2.

[0047] The surface of the first stop 7 furthest from the mounting base 2 is the first stop surface, and the surface of the second stop 8 facing the first stop 7 is the second stop surface. The first and second stop surfaces are spaced apart along the longitudinal direction of the machine body 1. The space between the first and second stop surfaces is used for the rubber roller to enter. Through the interaction between the first stop 7 and the rubber roller, and the interaction between the second stop 8 and the rubber roller, the position of the lower end of the rubber roller can be restricted.

[0048] To ensure the rubber wheel can smoothly enter between the first stop 7 and the second stop 8, and to ensure that the tilt angle of the rubber wheel can be adjusted, the distance between the first stop surface and the second stop surface needs to be slightly greater than the thickness of the rubber wheel, where the thickness of the rubber wheel is its dimension along its own axis. In other words, when the rubber wheel is located between the first stop 7 and the second stop 8, there should be a certain gap between the rubber wheel and the first stop surface or between the rubber wheel and the second stop surface, allowing the rubber wheel a certain amount of movement between the first stop 7 and the second stop 8.

[0049] When the rubber wheel is positioned between the first stop 7 and the second stop 8, the position of the abutment 4 is adjusted longitudinally along the body 1 so that the abutment 4 abuts against the rubber wheel in a direction away from the first stop 7. The rubber wheel, under the force of the abutment 4, abuts against the second stop 8. When the rubber wheel abuts against the second stop 8 under the force of the abutment 4, the upper end of the rubber wheel tilts in a direction away from the body 1. Under the action of the first stop 7, excessive tilting of the rubber wheel is limited, causing only a small angle of tilt. Thus, the stability of the rubber wheel, placed upright on the support device, can be ensured by the combined actions of the abutment 4, the second stop 8, and the first stop 7. When the rubber wheel needs to be transported, for example, from the rubber wheel storage area to the vicinity of the axle, the abutment 4, the first stop 7, and the second stop 8 can be used to stabilize the upright rubber wheel.

[0050] It should be noted that the rubber wheels are generally placed upright when installed onto the axle. In this embodiment, the rubber wheels are also placed upright when the wheel installation fixture transports them. Therefore, when transporting the rubber wheels to the axle accessories using the wheel installation fixture, there is no need to significantly adjust the wheel's angle, reducing the operator's workload and improving operational safety.

[0051] When the rubber wheel is transported to the vicinity of the axle, the position of the abutment 4 is adjusted longitudinally along the body 1 so that the abutment 4 moves in the direction close to the first stop 7. At this time, the upper end of the rubber wheel is tilted in the direction close to the body 1 and leans against the first stop 7 and the abutment 4. The second stop 8 is used to restrict the lower end of the rubber wheel from sliding in the direction away from the first stop 7 to prevent the rubber wheel from slipping off the support arm 3.

[0052] Then, the position of the rubber wheel is adjusted along the transverse and longitudinal directions of the machine body 1 using the position adjustment device, and the rubber wheel is rotated around its own axis to align the shaft hole of the rubber wheel with the mounting shaft of the axle, and to align each hole of the rubber wheel with each hole of the axle. During this process, when the rubber wheel is leaning against the first stop 7 and the abutment 4, it is convenient to rotate the rubber wheel as needed, and it can avoid interference between the upper end of the rubber wheel and the components above the axle.

[0053] In a further embodiment, the second stop surface can be made perpendicular to the longitudinal direction of the machine body 1. This can prevent the rubber wheels from tilting at an excessive angle during transportation, thus avoiding the problem of the rubber wheels tipping over.

[0054] Meanwhile, the first stop surface is parallel to the transverse direction of the body 1, the first stop surface and the second stop surface are set at an angle, and the distance between the first stop surface and the second stop surface gradually increases along the direction closer to the abutment mechanism.

[0055] The inclined first stop surface can increase the tilt angle range of the rubber wheel to a certain extent, thus increasing the adjustment range of the tilt angle of the rubber wheel. When the rubber wheel leans against the first stop surface, the upper end of the rubber wheel abuts against the abutment 4. The abutment 4 provides auxiliary support for the rubber wheel, which can still ensure the stability of the rubber wheel during the position adjustment process.

[0056] Align the shaft hole of the rubber wheel with the mounting shaft of the axle, and align each hole of the rubber wheel with each hole of the axle. Then, adjust the position of the abutment 4 along the longitudinal direction of the machine body 1 according to the axis of the axle to adjust the tilt angle of the rubber wheel so that the axis of the rubber wheel coincides with the axis of the axle.

[0057] The angle between the first stop surface and the reference surface is 80°~90°. Specifically, the angle between the first stop surface and the reference surface can be 87°. When adjusting the position of the mounting base 2 and the rubber wheel by the position adjustment device, the stability of the rubber wheel can be ensured, and the positional deviation between the shaft hole of the rubber wheel and the mounting shaft of the axle can be avoided.

[0058] In some embodiments, the first stop 7 and the second stop 8 are fixed relative to each other, and the distance between the first stop surface and the second stop surface is fixed.

[0059] In other embodiments, the first stop 7 and the second stop 8 are movably connected, so that the distance between the first stop surface and the second stop surface is adjustable to accommodate rubber wheels of different thicknesses.

[0060] Specifically, a first connecting rod is provided on the side of the first stop 7 near the second stop 8. The axis of the first connecting rod is arranged along the longitudinal direction of the machine body 1. Multiple first connecting holes are provided on the first connecting rod, and these holes are spaced apart along the axis of the first connecting rod. A second connecting rod is provided on the side of the second stop 8 near the first stop 7. The axis of the second connecting rod is arranged along the longitudinal direction of the machine body 1. Multiple second connecting holes are provided on the second connecting rod, and these holes are spaced apart along the axis of the second connecting rod. The first and second connecting rods overlap, and the first and second connecting holes correspond to each other. The first and second connecting rods are connected together using two bolts. By adjusting the overlap size of the first and second connecting rods as needed, so that the first connecting holes on the first connecting rod correspond to the second connecting holes at different positions on the second connecting rod, the distance between the first and second stop surfaces can be adjusted.

[0061] In this embodiment of the invention, the support arm 3 includes a support arm body and a roller.

[0062] The axis of the support arm body is set along the longitudinal direction of the machine body 1. One end of the support arm body is fixedly connected to the mounting base 2, and the other end of the support arm body is suspended in the air. The roller is rotatably sleeved on the outside of the support arm body, and the roller is parallel to the axis of the support arm body relative to the axis of the support arm body.

[0063] Each pair of support arms 3 has a roller. When the rubber wheel is placed on the pair of support arms 3, the rubber wheel contacts the roller of the pair of support arms 3. When a torque is manually applied to the rubber wheel, causing the rubber wheel to rotate around its own axis, the roller can adapt to rotate around the support arm body. The rolling friction between the rubber wheel and the roller can reduce the rotational resistance of the rubber wheel, improve the efficiency of adjusting the rotation of the rubber wheel, and reduce the labor intensity of the operator.

[0064] In this embodiment, the position adjustment device includes a transition connector 9, a first drive mechanism, and a second drive mechanism.

[0065] The transition connector 9 is disposed between the mounting base 2 and the body 1. The transition connector 9 is disposed on the body 1 in a reciprocating manner along the vertical direction of the body 1, and the mounting base 2 is disposed on the transition connector 9 in a reciprocating manner along the transverse direction of the body 1.

[0066] The first drive mechanism is disposed between the transition connector 9 and the body 1. The first drive mechanism is used to drive the transition connector 9 to slide back and forth relative to the body 1 so as to adjust the position of the mounting base 2 and the rubber wheel along the vertical direction of the body 1.

[0067] The second drive mechanism is disposed between the mounting base 2 and the transition connector 9. The second drive mechanism is used to drive the mounting base 2 to slide back and forth relative to the transition connector 9 so as to adjust the position of the mounting base 2 and the rubber wheel along the lateral side of the body 1.

[0068] In this embodiment, the first drive mechanism includes a lifting shaft 10, a lifting cylinder 11, a sprocket 12, and a chain 13.

[0069] The axis of the lifting shaft 10 is set along the transverse direction of the machine body 1, and the lifting shaft 10 can move vertically along the machine body 1.

[0070] The lifting cylinder 11 is located between the lifting shaft 10 and the machine body 1, and the axis of the lifting cylinder 11 is arranged vertically along the machine body 1. When the lifting cylinder 11 is running, it can drive the lifting shaft 10 to move vertically along the machine body 1.

[0071] The sprocket 12 is rotatably mounted on the lifting shaft 10, and the axis of rotation of the sprocket 12 relative to the lifting shaft 10 is parallel to the axis of the lifting shaft 10. The chain 13 is wound around the outside of the sprocket 12 and meshes with the sprocket 12 for transmission. The first end of the chain 13 is connected to the bottom end of the machine body 1, and the second end of the chain 13 is connected to the transition connector 9.

[0072] When the lifting cylinder 11 extends, it drives the lifting shaft 10 to rise vertically along the machine body 1. The distance between the lifting shaft 10 and the bottom of the machine body 1 increases, and the first end of the chain 13 rises, thereby driving the transition connector 9 to rise.

[0073] When the lifting cylinder 11 retracts, it drives the lifting shaft 10 to descend vertically along the body 1. The distance between the lifting shaft 10 and the bottom of the body 1 decreases, and the first end of the chain 13 descends, thereby causing the transition connector 9 to descend under its own weight and the action of the mounting base 2, support arm 3, and rubber wheel.

[0074] The aforementioned lifting cylinder 11 can be designed as a hydraulic cylinder driven by a hydraulic pump, or it can be designed as a jack structure.

[0075] The forces acting on both ends of chain 13 are equal, and the resultant force of its force on sprocket 12 is vertically downward along the machine body 1, and this resultant force passes through the center of sprocket 12. Since the central axis of sprocket 12, the central axis of lifting shaft 10, and the central axis of lifting cylinder 11 are located in the same plane, the force acting on lifting cylinder 11 is along its own axis. Lifting cylinder 11 is not subject to bending moment, which improves its stability and extends its service life.

[0076] A pair of sprockets 12 are provided, with their central axes coinciding. The pair of sprockets 12 are distributed at both ends of the lifting shaft 10. Each sprocket 12 corresponds to a chain 13, and each chain 13 is connected to the transition connector 9, which increases the number of connection points between the first drive mechanism and the transition connector 9 and can improve the stability of the transition connector 9.

[0077] To improve operational safety and aesthetics, the wheel mounting fixture in this embodiment also includes a protective cover, which is placed over the outside of the first drive mechanism.

[0078] Specifically, the protective cover includes a rigid protective net and a flexible protective cloth. The rigid protective net is fixedly installed on the side of the first driving mechanism away from the stop mechanism, and the flexible protective cloth is installed on the side of the first driving mechanism close to the stop mechanism.

[0079] The flexible protective fabric can be folded or stretched elastically. The first end of the flexible protective fabric is connected to the upper end of the body 1, and the second end is connected to the transition connector 9. When the transition connector 9 rises vertically along the body 1, the flexible protective fabric contracts or folds; when the transition connector 9 descends vertically along the body 1, the flexible protective fabric stretches or unfolds. The transition connector 9 can be located at any position, and the flexible protective fabric is present on the side of the first drive mechanism near the stop mechanism, effectively and adequately protecting and isolating the first drive mechanism.

[0080] In this embodiment, the second drive mechanism includes a linear bearing, a lead screw and nut transmission assembly, and a rotary handle 16.

[0081] A linear bearing is disposed between the mounting base 2 and the transition connector 9, with its axis positioned laterally along the machine body 1. A pair of linear bearings are provided, their axes parallel and spaced apart vertically along the machine body 1. The mounting base 2 is mounted to the transition connector 9 via the pair of linear bearings, allowing the mounting base 2 to slide relative to the transition connector 9 along the lateral direction of the machine body 1 while preventing rotation of the mounting base 2 relative to the transition connector 9.

[0082] The lead screw and nut drive assembly is positioned between the mounting base 2 and the transition connector 9. The lead screw of the lead screw and nut drive assembly is rotatably connected to the transition connector 9, and the nut of the lead screw and nut drive assembly is connected to the mounting base 2. One end of the lead screw of the lead screw and nut drive assembly is connected to the rotary handle 16. By rotating the rotary handle 16, the lead screw can be rotated relative to the transition connector 9, thereby causing the mounting base 2 to slide laterally along the machine body 1.

[0083] It should be noted that, under the driving action of the first drive mechanism, the longitudinal movement distance of the transition connector 9 along the body 1 ranges from 50 to 1285 mm. Under the driving action of the second drive mechanism, the transverse movement distance of the mounting base 2 along the body 1 is less than 800 mm.

[0084] In some embodiments, a traveling mechanism is provided on the body 1, which drives the body 1 to move at least longitudinally along the body 1 so that when installing the rubber wheel, the rubber wheel with the hole aligned can be brought close to the axle, so that the rubber wheel is hung on the mounting shaft of the axle.

[0085] In other embodiments, the position of the mounting base 2 is adjusted along the longitudinal direction of the body 1 by a position adjustment device. Specifically, the body 1 includes a base and a frame, the lateral direction of the base is the lateral direction of the body 1, the longitudinal direction of the base is the longitudinal direction of the body 1, and the vertical direction of the base is the vertical direction of the body 1. The support device, the transition connector 9, the first drive mechanism, and the second drive mechanism are all disposed on the frame.

[0086] The frame and the base are slidably connected, and the sliding direction of the frame relative to the base is along the longitudinal direction of the base. The position adjustment device also includes a third drive mechanism, which is disposed between the frame and the base, and can drive the frame to move relative to the base.

[0087] The third drive mechanism can be, but is not limited to, a gear and rack drive or a screw and nut drive structure.

[0088] In some implementations, the traveling mechanism includes a pair of omnidirectional wheels 14 and a pair of directional wheels 15, with the central axes of the pair of directional wheels 15 coinciding. The omnidirectional wheels 14 and directional wheels 15 are distributed longitudinally along the body 1. The arrangement of the omnidirectional wheels 14 allows the body 1 to also turn, thereby changing the direction of displacement of the body 1.

[0089] A handle 17 is provided on the machine body 1 to facilitate the operator to apply force and push and pull the tooling used for installing wheels.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
