Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to an assembly fixture. Background Technology

[0002] In the process of vehicle production, prototype vehicles are usually produced first. These prototype vehicles are then tested to determine any design defects or other issues that may exist.

[0003] Since prototype vehicles are not mass-produced, they usually do not have automated production lines. When installing wheels during the production of prototype vehicles, multiple workers are usually required to work together to install the wheels onto the vehicle body.

[0004] However, the wheels are quite heavy, and when installing them, multiple workers need to lift the wheels and repeatedly align them with the vehicle body, making the installation process quite difficult. Summary of the Invention

[0005] The purpose of this application is to provide an assembly fixture designed to solve the problem of difficult wheel installation.

[0006] This application provides an assembly fixture for assembling wheels to a vehicle body. The assembly fixture includes a bracket, a lifting mechanism, and a rotating mechanism. A rotating wheel is provided on the lower side of the bracket. The lifting device is connected to the bracket and is movable vertically relative to the bracket. The rotating mechanism is connected to the lifting mechanism and is used to support the wheel so that the wheel's axis intersects the vertical direction, and to drive the wheel to rotate around its own axis of rotation so that the mounting holes on the wheel are aligned with the mounting studs on the vehicle body.

[0007] According to the above technical means, the lower side of the bracket is equipped with a rotating wheel. The user can push the bracket to make the rotating wheel rotate, thereby pushing the bracket to move. In addition, through the cooperation of the lifting mechanism and the rotating mechanism, when it is necessary to install the wheel, the height of the lifting mechanism can be lowered first, and the wheel can be placed on the rotating mechanism in a simpler and more convenient way. Alternatively, by moving the bracket, the part of the rotating mechanism can be placed under the wheel, and the rotating mechanism can be raised by the lifting mechanism to lift the wheel.

[0008] Then the support can be moved to transport the wheel to the vehicle body. The height of the wheel can be adjusted by the lifting mechanism, and the angle of the wheel can be adjusted by the rotating mechanism to align the wheel with the vehicle body, and then the wheel can be installed on the vehicle body.

[0009] In the above process, no multiple workers are required. A single worker can move the wheel using the assembly fixture and adjust its height and angle through the lifting and rotating mechanisms to align the mounting holes on the wheel with the mounting studs on the vehicle body. This reduces the number of workers needed for wheel assembly, simplifies the process, and facilitates wheel installation onto the vehicle body. Furthermore, compared to manual wheel assembly, it avoids the risk of the wheel falling and other safety hazards for the worker, thus improving overall safety during wheel assembly.

[0010] In some embodiments, the rotating mechanism includes a first rotating rod, a second rotating rod, and a driving member. Both the first and second rotating rods are rotatably connected to the lifting mechanism and arranged along a first horizontal direction. Both the first and second rotating rods are capable of rotating about their own axes relative to the lifting mechanism. The extension directions of both the first and second rotating rods are adapted to be aligned with the axial direction of the wheel and perpendicular to the first horizontal direction. The first and second rotating rods are used to support the wheel, with the wheel supported between the first and second rotating rods. The driving member is connected to the first and / or second rotating rods and is used to drive the first and / or second rotating rods to rotate.

[0011] According to the above-mentioned technical means, compared with fixing the wheel and driving the wheel to rotate by means of grippers, robotic arms, etc., the first rotating rod and the second rotating rod have simple structures, are easy to process the rotating mechanism, and can facilitate the rotating mechanism to drive the wheel to rotate.

[0012] In some embodiments, the rotating mechanism further includes a first support member and a rotating roller, the first support member being connected to the lifting mechanism. A first rotating rod and a second rotating rod are both rotatably connected to the first support member. At least a portion of the first rotating rod and at least a portion of the second rotating rod are located on one side of the first support member in a second horizontal direction, and at least a portion of the first rotating rod and at least a portion of the second rotating rod are used to support a wheel, the second horizontal direction being perpendicular to the first horizontal direction. The rotating roller is rotatably connected to the first support member, the rotating rod being located on one side of the first support member in the second horizontal direction and above the first rotating rod and the second rotating rod. The rotating roller is used to contact the wheel, and the axis of rotation of the rotating roller relative to the first support member is adapted to be aligned radially with the wheel.

[0013] According to the above-mentioned technical means, in the process of adjusting the angle of the wheel by driving one of the first rotating rod and the second rotating rod to rotate through the driving component, the contact between the wheel and the rotating roller can drive the rotating roller to rotate. Compared with the wheel directly contacting the first support component, the friction force on the wheel can be reduced, thereby making it easier for the wheel to rotate and further facilitating the use of the rotating mechanism.

[0014] In some embodiments, the rotating mechanism further includes a base rotatably connected to a first support member, and a rotating roller rotatably connected to the base. The axis of rotation of the base relative to the first support member is adapted to be aligned with the axial direction of the wheel.

[0015] Based on the above-mentioned technical means, the assembly fixture can be made applicable to wheels of different sizes, thereby improving the applicability of the assembly fixture.

[0016] In some embodiments, the number of rotating rollers is multiple, and the multiple rotating rollers are adapted to be arranged circumferentially along the wheel.

[0017] According to the above technical means, the support component can provide support to multiple parts of the wheel in the circumferential direction through multiple rotating rollers, which can further improve the support effect of the rotating mechanism on the wheel, improve the stability of the wheel on the rotating mechanism, and ensure the normal function of the assembly fixture.

[0018] In some embodiments, the lifting mechanism includes a lifting device and a first driving device. The lifting device is slidably connected to the bracket in a vertical direction, and a rotating mechanism is connected to the first lifting device. The first driving device is connected to the bracket and located below the first lifting device, and is used to drive the first lifting device to slide relative to the bracket.

[0019] According to the above-mentioned technical means, the lifting device can be driven to move relative to the support by the first driving device, so that the lifting device can drive the rotating mechanism to rise or fall. The first driving device is located on the lower side of the lifting device, which makes it easier for the first driving device to drive the lifting device to move, thereby simplifying the structure of the first driving device and facilitating the spatial arrangement of the first driving device.

[0020] In some embodiments, the lifting device includes a lifting member and a second support member, the lifting member being slidably connected to a bracket. The second support member is slidably connected to the lifting member in a vertical direction, and a rotating mechanism is connected to the second support member. The lifting mechanism further includes a second driving device, which is connected to the lifting member and / or the bracket, for driving the second support member to slide relative to the lifting member.

[0021] Based on the aforementioned technical means, the height adjustment range of the second support member can be increased, thereby increasing the height adjustment range of the rotating mechanism. This allows the rotating mechanism to move the wheel to different heights, facilitating wheel installation. Simultaneously, when assembly fixtures are not required, the heights of both the second support member and the lifting member can be lowered, thus reducing the space occupied by the assembly fixtures.

[0022] In some embodiments, the second drive device includes a winding device, a first pulley, and a pull rope. The winding device is connected to a bracket; the first pulley is connected to a lifting member and located above the second support member. One end of the pull rope is connected to the winding device, and the other end of the pull rope is connected to the second support member, and the pull rope is wound around the first pulley.

[0023] Based on the aforementioned technical means, the winding device can be mounted on the support frame through the cooperation of the pull rope and the first pulley, thereby facilitating the spatial layout of the second drive device and, consequently, the spatial arrangement and processing of the lifting mechanism. Simultaneously, it reduces the tension on the first pull rope when the second support member is lifted, thus reducing the size of the winding device, facilitating its spatial arrangement, and lowering its cost.

[0024] In some embodiments, the assembly fixture further includes a controller and a pushing device, both electrically connected to the controller, which controls the rotating mechanism to drive the wheel to rotate. The pushing device is adapted to push the wheel toward the vehicle body so that mounting studs on the vehicle body pass through mounting holes on the wheel.

[0025] Based on the aforementioned technical means, the lifting and rotating mechanisms can be controlled by a controller to automatically adjust the height and angle of the wheels, thereby aligning the wheels automatically with the vehicle body. Simultaneously, a pusher can be used to move the wheels, automatically moving them onto the vehicle body.

[0026] In some embodiments, the assembly device further includes a fixing device and a rotating device. The fixing device is connected to the rotating device and is used to fix the nut. The rotating device is connected to a pushing device. The pushing device is adapted to push the wheel, the rotating device, and the fixing device toward the vehicle body so that the mounting stud on the vehicle body passes through the mounting hole on the wheel and the nut on the fixing device. The rotating device is used to drive the fixing device to rotate when the nut on the fixing device is fitted onto the mounting stud on the vehicle body, so that the nut secures the vehicle body and the wheel.

[0027] Based on the above technical means, after the assembly fixture is aligned with the wheel and the car body by the controller and the wheel is moved to the car body, the rotating device and the fixing device can be controlled to screw the nut onto the mounting stud on the car body, thereby automatically fixing the wheel to the car body and realizing automatic wheel assembly. In this way, the worker can realize automatic wheel installation by moving the wheel to the car body by the assembly fixture, which can further simplify the wheel assembly process and facilitate wheel assembly.

[0031] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0032] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0035] Since prototype vehicles are not mass-produced, they usually do not have automated production lines. When installing wheels during the production of prototype vehicles, multiple workers are usually required to work together to install them, and the wheels and the vehicle body need to be aligned repeatedly, which makes the installation of wheels quite difficult.

[0036] Based on this, such as Figures 1 to 4 As shown, this application provides an assembly fixture 10 for assembling wheels to the body of a vehicle. The assembly fixture 10 includes a bracket 3, a lifting mechanism 1, and a rotating mechanism 2.

[0037] The lower side of the support 3 is provided with a rotating wheel 32. The lifting device 11 is connected to the support 3 and can move vertically relative to the support 3.

[0038] The rotating mechanism 2 is connected to the lifting mechanism 1. It is used to support the wheel so that the wheel's axis intersects with the vertical direction, and to drive the wheel to rotate around its own axis of rotation so that the mounting hole on the wheel is aligned with the mounting stud on the vehicle body.

[0039] With the above configuration, the lower side of the bracket 3 is provided with a rotating wheel 32. The user can push the bracket 3 to rotate the rotating wheel 32, thereby moving the bracket 3. With the cooperation of the lifting mechanism 1 and the rotating mechanism 2, when it is necessary to install the wheel, the height of the lifting mechanism 1 can be lowered first, and the wheel can be placed on the rotating mechanism 2 in a simpler and more convenient way. Alternatively, by moving the bracket 3, part of the rotating mechanism 2 can be placed under the wheel, and the rotating mechanism 2 can be raised by the lifting mechanism 1, thereby lifting the wheel.

[0040] Then the support 3 can be moved to transport the wheel to the vehicle body. The height of the wheel can be adjusted by the lifting mechanism 1, and the angle of the wheel can be adjusted by the rotating mechanism 2 to align the wheel with the vehicle body, and then the wheel can be installed on the vehicle body.

[0041] In the above process, no multiple workers are required. A single worker can move the wheel using the assembly fixture 10 and adjust the height and angle of the wheel using the lifting mechanism 1 and the rotating mechanism 2, aligning the mounting holes on the wheel with the mounting studs on the vehicle body. This reduces the number of workers needed for wheel assembly, simplifies the assembly process, and facilitates wheel installation onto the vehicle body. Furthermore, compared to manual wheel assembly, it avoids the risk of the wheel falling and other safety hazards for the worker, thus improving the safety of wheel assembly.

[0042] For example, the intersection of the wheel's axis with the vertical direction can be either the wheel's axis being parallel to the horizontal plane, or there being an angle between the wheel's axis and the horizontal plane.

[0043] In some embodiments, such as Figures 1 to 4 As shown, the rotating mechanism 2 includes a first rotating rod 21, a second rotating rod 22, and a driving member.

[0044] The first rotating rod 21 and the second rotating rod 22 are both rotatably connected to the lifting mechanism 1 and are arranged along a first horizontal direction. Both the first rotating rod 21 and the second rotating rod 22 are capable of rotating relative to the lifting mechanism 1 about their own axis. The extension directions of both the first rotating rod 21 and the second rotating rod 22 are adapted to be aligned with the axial direction of the wheel and perpendicular to the first horizontal direction. The first rotating rod 21 and the second rotating rod 22 are used to support the wheel, with the wheel supported between the first rotating rod 21 and the second rotating rod 22.

[0045] The driving member is connected to at least one of the first rotating rod 21 and the second rotating rod 22, and is used to drive at least one of the first rotating rod 21 and the second rotating rod 22 to rotate.

[0046] It is understandable that both the first rotating rod 21 and the second rotating rod 22 are used to contact the outer peripheral surface of the wheel so that the wheel can be placed on the first rotating rod 21 and the second rotating rod 22.

[0047] This allows the wheel to be placed between the first rotating rod 21 and the second rotating rod 22, providing support for the wheel through the first rotating rod 21 and the second rotating rod 22.

[0048] By setting a driving component, the driving component can drive at least one of the first rotating rod 21 and the second rotating rod 22 to rotate. Taking the driving component driving the first rotating rod 21 to rotate as an example, during the rotation of the first rotating rod 21, the first rotating rod 21 contacts the wheel and can drive the wheel to rotate, thereby adjusting the angle of the wheel.

[0049] At the same time, the wheel can drive the second rotating rod 22 to rotate, thereby reducing the friction between the wheel and the second rotating rod 22, so that the driving component can drive the first rotating rod 21 to drive the wheel to rotate.

[0050] Compared to fixing the wheel with a chuck, robotic arm, etc. and driving the wheel to rotate, the first rotating rod 21 and the second rotating rod 22 have simpler structures, are easier to process with the rotating mechanism 2, and can easily drive the wheel to rotate with the rotating mechanism 2.

[0051] For example, the driving component can be a rotary motor, a hydraulic motor, etc.

[0052] For example, the extension directions of the first rotating rod 21 and the second rotating rod 22 can be parallel to the horizontal plane, in which case the axis of the wheel placed between the first rotating rod 21 and the second rotating rod 22 is parallel to the horizontal plane.

[0053] For example, the extension directions of the first rotating rod 21 and the second rotating rod 22 may form an angle with the horizontal plane. In this case, the axial direction of the wheel placed between the first rotating rod 21 and the second rotating rod 22 also forms an angle with the horizontal plane. The wheel can be supported by a support device or fixed by a fixing device to prevent the wheel from falling off the first rotating rod 21 and the second rotating rod 22.

[0054] For example, the first horizontal direction can be consistent with the arrangement direction of the lifting mechanism 1 and the rotating mechanism 2, or it can be perpendicular to the arrangement direction of the lifting mechanism 1 and the rotating mechanism 2, etc.

[0055] In some other embodiments, the rotating mechanism 2 may also be a rotatable gripper, a robotic arm, etc.

[0056] In some embodiments, such as Figures 1 to 4As shown, the rotating mechanism 2 also includes a first support member 24 and a rotating roller 25. The first support member 24 is connected to the lifting mechanism 1. The first rotating rod 21 and the second rotating rod 22 are both rotatably connected to the first support member 24. At least a portion of the first rotating rod 21 and at least a portion of the second rotating rod 22 are located on one side of the first support member 24 in a second horizontal direction, and at least a portion of the first rotating rod 21 and at least a portion of the second rotating rod 22 are used to support the wheel, and the second horizontal direction is perpendicular to the first horizontal direction.

[0057] The rotating mechanism 2 further includes a rotating roller 25, which is rotatably connected to the first support member 24. The rotating rod is located on one side of the first support member 24 in the second horizontal direction and above the first rotating rod 21 and the second rotating rod 22. The rotating roller 25 is used to contact the wheel, and the axis of rotation of the rotating roller 25 relative to the first support member 24 is adapted to be aligned with the radial direction of the wheel.

[0058] With the above configuration, the rotation axis of the rotating roller 25 relative to the first support member 24 is consistent with the radial direction of the wheel. Thus, when the wheel rotates, the moving direction of the part of the wheel that contacts the rotating roller 25 is perpendicular to the rotation axis of the rotating roller 25, so that the wheel can drive the rotating roller 25 to rotate.

[0059] In this way, while the first support member 24 provides support for the wheel through the first rotating rod 21 and the second rotating rod 22, it can also provide support for the wheel through the rotating roller 25, thereby enabling the rotating mechanism 2 to support the wheel more stably.

[0060] Furthermore, during the process of adjusting the wheel angle by driving one of the first rotating rod 21 and the second rotating rod 22 to rotate through the driving member, the wheel and the rotating roller 25 come into contact, which can drive the rotating roller 25 to rotate. Compared with the wheel directly contacting the first support member 24, the friction force on the wheel can be reduced, thereby making it easier for the wheel to rotate and further facilitating the use of the rotating mechanism 2.

[0061] In some other embodiments, ball bearings can also be provided on the first support member 24. During the rotation of the wheel, the ball bearings are driven to roll and remain stationary, which can also reduce the magnitude of the friction force on the wheel.

[0062] In some embodiments, the rotating mechanism 2 further includes a first mounting sleeve 27 and a second mounting sleeve 28, both of which are connected to the lower side of the first support member 24 and located at both ends of the first support member 24 in the first horizontal direction.

[0063] The axial direction of the first mounting sleeve 27 is aligned with the axial direction of the first rotating rod 21. The first rotating rod 21 passes through the first mounting sleeve 27 and is rotatably connected to it. The axial direction of the second mounting sleeve 28 is aligned with the axial direction of the second rotating rod 22. The second rotating rod 22 passes through the second mounting sleeve 28 and is rotatably connected to it.

[0064] In this way, the first rotating rod 21 and the second rotating rod 22 can be installed by the first mounting sleeve 27 and the second mounting sleeve 28 respectively. Compared with opening holes or slots in the first support member 24, the machining difficulty of the rotating mechanism 2 can be simplified and the machining of the rotating mechanism 2 can be facilitated.

[0065] In some embodiments, such as Figures 1 to 4 As shown, the rotating mechanism 2 also includes a base 26, which is rotatably connected to the first support member 24, and the rotating roller 25 is rotatably connected to the base 26.

[0066] The axis of rotation of the base 26 relative to the first support 24 is adapted to be aligned with the axis of the wheel.

[0067] With the above configuration, by rotating the base 26 relative to the first support member 24, the direction of the rotation axis of the rotating roller 25 can be adjusted. Thus, when assembling wheels of different sizes using a conversion jig, the rotation axis of the rotating roller 25 can be aligned with the radial direction of the wheel by rotating the base 26, so that different wheels can drive the rotating roller 25 to rotate, thereby ensuring that the friction force on the wheel is reduced by rotating the roller 25.

[0068] This allows the assembly fixture 10 to be adapted to wheels of different sizes, thereby improving the applicability of the assembly fixture 10.

[0069] In some other embodiments, the rotating roller 25 may also be directly rotatably connected to the first support member 24. Alternatively, the base 26 may also be fixed to the first support member 24.

[0070] In some embodiments, such as Figures 1 to 4 As shown, there are multiple rotating rollers 25, which are adapted to be arranged circumferentially along the wheel.

[0071] In this way, during the process of installing the wheel through the assembly fixture 10, the support member can provide support to multiple parts of the wheel in the circumferential direction through multiple rotating rollers 25, which can further improve the support effect of the rotating mechanism 2 on the wheel, improve the stability of the wheel on the rotating mechanism 2, and ensure the normal function of the assembly fixture 10.

[0072] In some other embodiments, the plurality of rotating rollers 25 may also be arranged along a first horizontal direction.

[0073] For example, the extension directions of the first rotating rod 21 and the second rotating rod 22 form an angle with the horizontal plane, and are located in the same plane as the direction from the lifting mechanism 1 to the rotating mechanism 2. Along the direction from the lifting mechanism 1 to the rotating mechanism 2, the distance between the first rotating rod 21 and the second rotating rod 22 and the ground gradually increases.

[0074] After the wheel is placed on the first rotating rod 21 and the second rotating rod 22, the wheel will gradually tilt towards the first support member 24. Under the action of gravity, the wheel can abut against the rotating roller 25 and will not tilt away from the first support member 24, thus enabling the rotating mechanism 2 to support the wheel more stably.

[0075] In some embodiments, the first support member 24 includes a first frame, and the square shape may be composed of rods, tubes (e.g., round tubes, square tubes), etc.

[0076] For example, the shape of the first frame can be square, triangle, etc.

[0077] Compared to support plates, the first frame has higher structural strength and occupies less space. It also makes it easier to install other components onto the first frame, thus facilitating the processing and use of the first support member 24.

[0078] In some examples, the first frame is made of square steel. Square steel is less expensive and easier to process.

[0079] In some other embodiments, the first support member 24 may also be a support plate, support block, etc.

[0080] In some embodiments, such as Figures 1 to 4 As shown, the lifting mechanism 1 includes a lifting device 11 and a first driving device 12. The lifting device 11 is slidably connected to the support 3 in the vertical direction, and the rotating mechanism 2 is connected to the lifting device 11. The first driving device 12 is connected to the support 3 and is located below the lifting device 11, and is used to drive the lifting device 11 to slide relative to the support 3.

[0081] With the above configuration, the lifting device 11 can be moved relative to the bracket 3 by the first driving device 12, so that the lifting device 11 can drive the rotating mechanism 2 to rise or fall. The first driving device 12 is located on the lower side of the lifting device 11, which makes it easier for the first driving device 12 to drive the lifting device 11 to move, thereby simplifying the structure of the first driving device 12 and facilitating the spatial arrangement of the first driving device 12.

[0082] For example, the first drive device 12 can be an air pump, a hydraulic rod, etc.

[0083] In some other embodiments, the first drive device 12 may also be located on one side of the lifting device 11 in the horizontal direction.

[0084] In some embodiments, such as Figures 1 to 4 As shown, the lifting device 11 includes a lifting member 111 and a second support member 112. The lifting member 111 is slidably connected to the bracket 3. The second support member 112 is slidably connected to the lifting member 111 in the vertical direction, and the rotating mechanism 2 is connected to the second support member 112.

[0085] The lifting mechanism 1 also includes a second drive device 13, which is connected to at least one of the lifting member 111 and the bracket 3, and is used to drive the second support member 112 to slide relative to the lifting member 111.

[0086] With the above configuration, while the lifting member 111 is driven to rise and fall relative to the bracket 3 by the first driving device 12, the second support member 112 can also be driven to rise and fall relative to the lifting member 111 by the second driving device 13. This increases the height adjustment range of the second support member 112, thereby increasing the height adjustment range of the rotating mechanism 2, so that the rotating mechanism 2 can drive the wheel to move to different heights, which is convenient for the installation of the wheel.

[0087] At the same time, when the assembly fixture 10 is not needed, the height of the second support member 112 and the lifting member 111 can be reduced simultaneously, thereby reducing the space occupied by the assembly fixture 10, so as to facilitate the storage and movement of the assembly fixture 10, and further facilitate the use of the assembly fixture 10.

[0088] In some other embodiments, the second support 112 may also be fixed together with the lifting member 111.

[0089] In some embodiments, such as Figures 1 to 4 As shown, the second drive device 13 includes a winding device 131, a first pulley 133, and a pull rope 132. The winding device 131 is connected to the bracket 3. The first pulley 133 is connected to the lifting member 111 and is located above the second support member 112. One end of the pull rope 132 is connected to the winding device 131, and the other end of the pull rope 132 is connected to the second support member 112, and the pull rope 132 is wound around the first pulley 133.

[0090] In this way, the winding device 131 can be used to wind and stretch the rope 132 to apply tension to the second support member 112, thereby driving the second support member 112 and the rotating mechanism 2 to rise. Similarly, the winding device 131 can be used to release the rope 132 to lower the second support member 112 and the rotating mechanism 2.

[0091] By using the pull rope 132 and the first pulley 133, the winding device 131 can be mounted on the bracket 3. Compared to directly mounting the winding device 131 on the lifting member 111, this facilitates the spatial arrangement of the winding device 131, thereby facilitating the spatial layout of the second drive device 13 and, consequently, the spatial arrangement and processing of the lifting mechanism 1.

[0092] Meanwhile, by setting the first pulley 133, compared to the winding device 131 being directly connected to the second support member 112 via the pull rope 132, the tension on the first pull rope 132 when driving the second support member 112 to rise can be reduced. This reduces the amount of force required to be output by the winding device 131, allowing for the selection of a lower-power winding device 131, reducing its size, facilitating its spatial arrangement, and lowering its cost.

[0093] In some other embodiments, the winding device 131 may be directly connected to the lifting member 111, or the second driving device 13 may include an air pump, a hydraulic rod, etc., which may be directly connected to the lifting member 111 to drive the second support member 112 to move relative to the lifting member 111.

[0094] In some embodiments, such as Figures 1 to 4 As shown, the second drive device 13 further includes a second pulley 134 and a third pulley 135. The second pulley 134 is connected to the lifting member 111 and is located below the first pulley 133. The third pulley 135 is connected to the lifting member 111 and is located above the second pulley 134. The pull rope 132 is sequentially wound around the first pulley 133, the second pulley 134, and the third pulley 135.

[0095] With the above arrangement, the pull rope 132 is simultaneously wound around the first pulley 133, the second pulley 134, and the third pulley 135, which can further reduce the tension on the portion of the pull rope 132 between the second support member 112 and the third pulley 135, the portion of the pull rope 132 between the third pulley 135 and the second pulley 134, the portion of the pull rope 132 between the second pulley 134 and the first pulley 133, and the portion of the pull rope 132 between the first pulley 133 and the winding device 131.

[0096] This can further reduce the amount of force required to output the winding device 131, thereby allowing the use of a winding device 131 with lower power, further reducing the size of the winding device 131, further facilitating the spatial arrangement of the winding device 131, and further reducing the cost of the winding device 131.

[0097] In some other embodiments, the second pulley 134 may also be connected to the second support 112 or the bracket 3. Alternatively, the second drive may include more pulleys, such as a fourth pulley, a fifth pulley, etc.

[0098] In some embodiments, such as Figures 1 to 4 As shown, the bracket 3 includes a base 31, a first mounting rod 33, a second mounting rod 34, a first support rod 35, and a second support rod 36.

[0099] The first drive device 12 includes an air pump, and both the air pump and the winding device 131 are connected to the base 31. A first mounting rod 33 and a second mounting rod 34 are both connected to the base 31 and are arranged in a direction perpendicular to the arrangement direction of the rotating mechanism 2 and the lifting mechanism 1. A first support rod 35 is connected to the first mounting rod 33, and a second support rod 36 is connected to the second mounting rod 34. Both the first support rod 35 and the second support rod 36 extend along the arrangement direction of the lifting mechanism 1 and the rotating mechanism 2.

[0100] The rotating wheel 32 includes a first rotating wheel 32, a second rotating wheel 32, a third rotating wheel 32, and a fourth rotating wheel 32. The first and second rotating wheels 32 are rotatably connected to the lower side of the base 31 and are located at both ends of the base 31 in a direction perpendicular to the arrangement direction of the rotating mechanism 2 and the lifting mechanism 1. The third rotating wheel 32 is rotatably connected to the lower side of the end of the first support rod 35 away from the base 31, and the fourth rotating wheel 32 is rotatably connected to the lower side of the end of the second support rod away from the base 31.

[0101] By making the first support rod 35 and the second support rod 36 extend along the arrangement direction of the lifting mechanism 1 and the rotating mechanism 2, and by enabling the bracket 3 to contact the ground through the first rotating wheel 32, the second rotating wheel 32, the third rotating wheel 32 and the fourth rotating wheel 32, the bracket 3 can provide more stable support for the lifting mechanism 1 and the rotating mechanism 2, avoid the assembly fixture 10 from tilting, and ensure the normal use of the assembly fixture 10.

[0102] In some embodiments, such as Figures 1 to 4 As shown, the first mounting rod 33 and the second mounting rod 34 extend vertically. The first mounting rod 33 has a first sliding groove, the opening of which faces the second mounting rod 34, and the first sliding groove extends vertically to the upper end of the first mounting rod 33. The second mounting rod 34 has a second sliding groove, the opening of which faces the first mounting rod 33, and the second sliding groove extends vertically to the upper end of the second mounting rod 34.

[0103] The lifting component 111 includes a first slide rod 1111 and a second slide rod 1112. Both the first slide rod 1111 and the second slide rod 1112 extend vertically. The first slide rod 1111 slides in a first slide groove, and the second slide rod 1112 slides in a second slide groove.

[0104] The first slide rod 1111 is provided with a third slide groove, the opening of which faces the second slide rod 1112. The second slide rod 1112 is provided with a fourth slide groove, the opening of which faces the first slide rod 1111.

[0105] The second support member 112 includes a second frame 1121, a third slide rod 1122, and a fourth slide rod 1123. The third slide rod 1122 is located between the first slide rod 1111 and the second slide rod 1112, and the fourth slide rod 1123 is located between the third slide rod 1122 and the second slide rod 1112. The third slide rod 1122 has a first sliding post on the side facing the first slide rod 1111, and the first sliding post at least partially extends into the third slide groove. The fourth slide rod 1123 has a second sliding post on the side facing the second slide rod 1112, and the second sliding post at least partially extends into the fourth slide groove.

[0106] The second frame 1121 is located on the side of the lifting member 111 facing the rotating mechanism 2, and is connected to both the third slide rod 1122 and the fourth slide rod 1123. The rotating mechanism 2 is connected to the second frame 1121.

[0107] With the above configuration, the first slide rod 1111 and the second slide rod 1112 can slide within the first slide groove and the second slide groove respectively, thereby enabling the lifting member to move relative to the support 3. The first sliding column and the second sliding column can slide within the third slide groove and the fourth slide groove respectively, thereby enabling the third slide rod 1122 and the fourth slide rod 1123 to slide relative to the first slide rod 1111 and the second slide rod 1112, and thus enabling the second support member 112 to move relative to the lifting member 111.

[0108] In some embodiments, such as Figures 1 to 4 As shown, the lifting component 111 also includes a first connecting rod 1113 and a second connecting rod 1114. The first connecting rod 1113 is connected between the upper end of the first slide rod 1111 and the upper end of the second slide rod 1112, and the third pulley 135 is connected to the lower side of the first connecting rod 1113.

[0109] The second connecting rod 1114 is connected between the lower end of the first slide rod 1111 and the lower end of the second slide rod 1112, and the second pulley 134 is connected to the upper side of the second connecting rod 1114.

[0110] In this way, the third pulley 135 and the second pulley 134 can be supported by the first connecting rod 1113 and the second connecting rod 1114 respectively.

[0111] In some embodiments, such as Figure 3 As shown, the bracket 3 also includes a third connecting rod 37, which connects the upper end of the first mounting rod 33 and the upper end of the second mounting rod 34. The first pulley 133 is connected to the lower side of the third connecting rod 37.

[0112] This allows the first pulley 133 to be supported via the third connecting rod 37.

[0113] In some embodiments, such as Figures 1 to 4 As shown, the conversion fixture also includes a fourth connecting rod 4 and a fifth connecting rod 5, both of which extend along the arrangement direction of the lifting mechanism 1 and the rotating mechanism 2, and in a direction perpendicular to the arrangement direction of the rotating mechanism 2 and the lifting mechanism 1. Both the fourth connecting rod 4 and the fifth connecting rod 5 are connected between the first frame and the second frame 1121.

[0114] In this way, the first frame and the second frame 1121 can be connected together by the fourth connecting rod 4 and the fifth connecting rod 5, thereby fixing the rotating structure and the lifting mechanism 1.

[0115] In some embodiments, such as Figure 3 , Figure 4 As shown, the bracket 3 also includes a handle 38, which is connected to the side of the bracket 3 away from the rotating mechanism 2.

[0116] This allows the worker to hold the handle 38 to push the assembly fixture 10, making it easy for the worker to move the assembly fixture 10 and for the worker to use the assembly fixture 10.

[0117] In some embodiments, such as Figures 1 to 4 As shown, the assembly fixture 10 also includes a controller 6 and a pushing device. The rotating mechanism 2 and the pushing device are both electrically connected to the controller 6. The controller 6 is used to control the rotating mechanism 2 to drive the wheel to rotate so that the mounting hole on the wheel is aligned with the mounting stud on the vehicle body.

[0118] The pushing device is adapted to push the wheel toward the vehicle body so that the mounting studs on the vehicle body pass through the mounting holes on the wheel.

[0119] In this way, the lifting mechanism 1 and the rotating mechanism 2 can be controlled by the controller 6 to automatically adjust the height and angle of the wheels so that the wheels are automatically aligned with the vehicle body. At the same time, the pusher can be used to move the wheels, thereby automatically moving the wheels onto the vehicle body.

[0120] This further simplifies the wheel assembly process and makes wheel assembly more convenient.

[0121] In some examples, both the controller 6 and the actuation device are connected to the first frame.

[0122] For example, the actuating device can be a linear motor, an air pump, a hydraulic rod, etc.

[0123] In some embodiments, such as Figures 1 to 4As shown, the assembly device also includes a fixing device and a rotating device. The fixing device is connected to the rotating device and is used to fix the nut. The rotating device is connected to the pushing device.

[0124] The pushing device is adapted to move the wheel, the rotating device and the fixing device toward the vehicle body so that the mounting studs on the vehicle body pass through the mounting holes on the wheel and the nuts on the fixing device.

[0125] The rotating device is used to drive the fixing device to rotate when the nut on the fixing device is fitted onto the mounting stud on the vehicle body, so that the nut secures the vehicle body and the wheels.

[0126] In this way, after the assembly fixture 10 is aligned with the wheel and the car body by the controller 6 and the wheel is moved to the car body, the rotating device and the fixing device can be controlled to screw the nut onto the mounting stud on the car body, thereby automatically fixing the wheel to the car body and realizing automatic wheel assembly. Thus, the worker can move the wheel to the car body by the assembly fixture 10 to realize automatic wheel installation, which can further simplify the wheel assembly process and facilitate wheel assembly.

[0127] For example, the rotating device can be a rotary motor, a hydraulic motor, etc.

[0128] In some embodiments, both the first rotating rod 21 and the second rotating rod 22 are equipped with pressure sensors. The pressure sensors can detect the magnitude of the pressure on the first rotating rod 21 and the second rotating rod 22, thereby determining whether the wheel is properly loaded.

[0129] In some embodiments, the controller 6 has a memory function, which can save vehicle model data, etc. When the assembly fixture 10 is used for the second time, the corresponding vehicle model can be selected, so that the assembly fixture 10 is automatically adjusted to the corresponding position, thereby further facilitating the installation of wheels.

[0130] For example, vehicle model data may include the vehicle's wheelbase, track width, wheel mounting coordinates, height of lifting mechanism 1, and nut preload, etc.

[0131] By determining the preload of the nut, it can be determined whether the nut is installed correctly, thus ensuring the proper assembly of the wheel.

[0132] In some embodiments, the vehicle body may be equipped with calipers. Before moving the wheel via the assembly fixture 10, the corresponding mounting bolts can be pre-positioned in the calipers. The vehicle body may also include locking components (e.g., electromagnetic locks, retaining pins, etc.), which are controlled by a control element to lock the mounting bolts, thus securely fixing them within the calipers.

[0133] Specifically, the threaded section of the mounting bolt can extend approximately 10-30mm from the end of the caliper to facilitate insertion of the mounting bolt into the mounting hole on the wheel.

[0134] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0135] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
