Description

Technical Field

[0001] This application relates to the field of automotive manufacturing technology, and in particular to an auxiliary installation device for tires and wheels in automobile production. Background Technology

[0002] In the automotive manufacturing industry, tire and wheel installation is a crucial process. Traditional tire and wheel installation relies primarily on manual labor, requiring workers to expend considerable physical effort to precisely fit the tire onto the wheel and press it in place. This method is not only inefficient, but its installation accuracy is also affected by worker skill and fatigue, making it difficult to guarantee consistency. With the rapid development of the automotive industry and the ever-increasing demands for production efficiency and product quality, traditional manual installation methods are increasingly unable to meet the needs of large-scale, high-quality production.

[0003] A search revealed Chinese Patent Publication No. CN214560704U, which discloses an auxiliary installation device for tires and wheel hubs in automobile production. The device includes a support base, a placement platform above the support base, a movable support plate below the placement platform, and two support columns below the movable support plate. The bottom of each support column is fixedly connected to the top of the support base, and the two support columns are connected by a connecting plate. The connecting plate and the movable support plate are connected by a lifting assembly. Two limiting plates are fixedly connected to the bottom of the placement platform, penetrating the movable support plate. A sliding groove is provided on the side of each support column away from the connecting plate. This auxiliary installation device for tires and wheel hubs in automobile production belongs to the field of assembly technology. It facilitates the movement of the entire device and allows for easy adjustment of the height of the placement platform. When the wheel hub is placed directly on top of the placement platform, a spring provides cushioning.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: These devices largely rely on manual or simple mechanical structures for positioning, lacking precise alignment control between the tire edge and the rim mounting surface, which can easily lead to installation deviations or localized stress concentrations. The fit between the tire and the rim requires uniform pressure application; traditional equipment struggles to automatically adjust pressure according to tire specifications and lacks elastic cushioning and adaptive limiting functions, potentially damaging the tire or rim surface. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a tire and wheel hub auxiliary installation device for automobile production.

[0006] This application provides an auxiliary installation device for tires and rims in automobile production, which adopts the following technical solution: an auxiliary installation device for tires and rims in automobile production includes a base, a rim body is provided on the top of the base, and an auxiliary component is provided on one side of the base;

[0007] The auxiliary component includes a transverse slide rail, a motor mounting plate, a second servo motor, a bidirectional lead screw, a first support arm, and a tire pressure roller. The transverse slide rail is located on one side of the wheel hub body, and the motor mounting plate is fixedly installed on one side of the transverse slide rail. A dovetail groove is formed inside the transverse slide rail. The second servo motor is fixedly installed on one side of the motor mounting plate, and the bidirectional lead screw is fixedly installed at the output end of the second servo motor. The first support arm is threaded onto one side of the bidirectional lead screw, and the tire pressure roller is movably installed on one side of the first support arm.

[0008] Through the above scheme, the lateral slide rail and the two-way lead screw work together to achieve synchronous reverse movement of the two support arms, and the tire pressure roller precisely controls the tire pressing angle.

[0009] Optionally, the auxiliary component further includes a second support arm, a limiting plate, a limiting post, an auxiliary roller, a limiting ring, and a spring. The second support arm is threaded onto one side of the bidirectional lead screw. A limiting plate is fixedly connected to one side of the second support arm. A hole is opened through the top of the limiting plate, and a limiting post is movably installed inside the hole. An auxiliary roller is movably installed at the bottom of the limiting post. A limiting ring is fixedly connected to one side of the limiting post. A spring is fixedly connected to the top of the limiting ring. The spring is sleeved on one side of the limiting post and is fixedly connected between the limiting ring and the limiting plate.

[0010] The above scheme, in conjunction with the auxiliary roller, forms an elastic limiting structure to ensure balanced pressure during tire installation.

[0011] Optionally, the auxiliary component further includes a sliding sleeve housing, an internally threaded slide rod, a one-way lead screw, and a first servo motor. The sliding sleeve housing is fixedly installed on one side of the base. An internally threaded slide rod is movably installed inside the sliding sleeve housing. A one-way lead screw is threaded into the internal thread of the internally threaded slide rod. The one-way lead screw is fixedly installed at the output end of the first servo motor. The first servo motor is fixedly installed inside the sliding sleeve housing.

[0012] The above solution uses a servo motor to drive a lead screw to adjust the height of the component, and a dovetail slide structure to ensure lateral movement stability.

[0013] Optionally, the first support arm and the second support arm are symmetrically arranged around the bidirectional lead screw, and the tire pressure roller and the limiting plate are symmetrically arranged around the bidirectional lead screw.

[0014] Through the above scheme, the symmetrical movement of the two support arms forms a clamping mechanism, which synchronously adjusts the relative position of the tire pressure roller and the auxiliary roller.

[0015] Optionally, the auxiliary roller is movably connected to the top of the hub body.

[0016] The above solution increases friction through the anti-slip layer on the roller surface, and enables the bearing structure to rotate flexibly, effectively guiding the tire installation trajectory.

[0017] Optionally, the tire pressure roller is movably connected to the top of the wheel hub body.

[0018] The above solution uses wear-resistant materials to make tire pressing rollers, which are combined with servo motors to achieve adjustable tire pressing operation.

[0019] Optionally, one end of the internally threaded slide rod extends to the outside of the slide sleeve housing and is movably connected to a support block, the bottom of which is fixedly connected to the top of the base.

[0020] The above solution enhances the rigidity of the equipment through a multi-point support structure, and the adjustable screw system enables precise height positioning.

[0021] Optionally, the auxiliary roller is movably mounted on the bottom of the limiting post via a bearing, and the outer surface of the auxiliary roller is provided with a rubber anti-slip layer.

[0022] The above solution uses a buffer system composed of a limit ring and a spring to effectively absorb assembly impact and ensure the stability of equipment operation.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] 1. This utility model comprises a transverse slide rail, a second servo motor, a bidirectional lead screw, a first support arm, a tire pressure roller, a second support arm, and auxiliary rollers. The second servo motor drives the bidirectional lead screw to rotate, causing the first and second support arms to move symmetrically along the dovetail groove of the transverse slide rail. This movement simultaneously moves the tire pressure roller and the auxiliary roller closer to or further away from the wheel hub. The tire pressure roller applies uniform pressure to the tire edge, while the auxiliary roller supports the inner side of the tire. The synchronous movement of the bidirectional lead screw achieves tire positioning and pressing, thus enabling the device to precisely press and stably support the tire edge during installation through bidirectional lead screw transmission and a symmetrically distributed roller structure, improving the wheel hub-tire fit accuracy.

[0025] 2. This utility model, through the inclusion of a sliding sleeve housing, an internally threaded sliding rod, a one-way lead screw, a first servo motor, a limiting post, a limiting ring, and springs, uses the first servo motor to drive the one-way lead screw to rotate, causing the internally threaded sliding rod to slide up and down along the sliding sleeve housing, thus adjusting the overall height of the auxiliary assembly to accommodate wheel hubs of different sizes. Simultaneously, the limiting post is elastically connected to the limiting plate via a spring, allowing the auxiliary roller to adaptively float with the undulations of the tire surface. This maintains contact pressure with the tire through the spring's elastic force while avoiding wear caused by rigid contact. Therefore, this device achieves height adjustment via a lead screw and nut transmission and utilizes an elastic support structure for flexible auxiliary positioning of tires of different sizes, improving the equipment's versatility and installation stability.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] Please see Figure 1 A tire and wheel hub auxiliary installation device for automobile production includes a base 1, a wheel hub body 2 is provided on the top of the base 1, and an auxiliary component 3 is provided on one side of the base 1.

[0034] Please see Figures 2 to 4Auxiliary component 3 includes a transverse slide rail 305, a motor mounting plate 306, a second servo motor 307, a bidirectional lead screw 308, a first support arm 309, and a tire pressure roller 310. The transverse slide rail 305 is located on one side of the wheel hub body 2. The motor mounting plate 306 is fixedly installed on one side of the transverse slide rail 305. A dovetail groove is opened inside the transverse slide rail 305. The second servo motor 307 is fixedly installed on one side of the motor mounting plate 306. The bidirectional lead screw 308 is fixedly installed at the output end of the second servo motor 307. The first support arm 309 is threaded onto one side of the bidirectional lead screw 308. The tire pressure roller 310 is movably installed on one side of the first support arm 309.

[0035] The first support arm 309 and the second support arm 311 are symmetrically arranged with the bidirectional lead screw 308 as the center, and the tire pressure roller 310 and the limiting plate 312 are symmetrically arranged with the bidirectional lead screw 308 as the center.

[0036] The tire pressure roller 310 is movably connected to the top of the wheel hub body 2.

[0037] The auxiliary component 3 also includes a second support arm 311, a limiting plate 312, a limiting post 313, an auxiliary roller 314, a limiting ring 315, and a spring 316. The second support arm 311 is threaded onto one side of the bidirectional lead screw 308. The limiting plate 312 is fixedly connected to one side of the second support arm 311. A hole is opened through the top of the limiting plate 312, and the limiting post 313 is movably installed inside the hole. The auxiliary roller 314 is movably installed at the bottom of the limiting post 313. The limiting ring 315 is fixedly connected to one side of the limiting post 313. The spring 316 is fixedly connected to the top of the limiting ring 315. The spring 316 is sleeved on one side of the limiting post 313 and is fixedly connected between the limiting ring 315 and the limiting plate 312.

[0038] The auxiliary roller 314 is movably connected to the top of the hub body 2.

[0039] The auxiliary roller 314 is movably mounted on the bottom of the limiting post 313 via a bearing, and the outer surface of the auxiliary roller 314 is provided with a rubber anti-slip layer.

[0040] The auxiliary component 3 also includes a sliding sleeve housing 301, an internally threaded slide rod 302, a one-way lead screw 303, and a first servo motor 304. The sliding sleeve housing 301 is fixedly installed on one side of the base 1. The internally threaded slide rod 302 is movably installed inside the sliding sleeve housing 301. The one-way lead screw 303 is threaded into the internal thread of the internally threaded slide rod 302. The one-way lead screw 303 is fixedly installed at the output end of the first servo motor 304. The first servo motor 304 is fixedly installed inside the sliding sleeve housing 301.

[0041] One end of the internally threaded slide bar 302 extends to the outside of the slide sleeve housing 301 and is movably connected to a support block. The bottom of the support block is fixedly connected to the top of the base 1.

[0042] Further explanation is needed regarding the auxiliary component 3. Its main function is to provide precise positioning, pressure application, and adaptive adjustment during the installation of the car tire and rim, ensuring efficient and stable contact between the tire and rim. This component, through the cooperation of components such as the transverse slide rail 305, the bidirectional lead screw 308, and the second servo motor 307, achieves symmetrical synchronous movement of the tire pressure roller 310 and the auxiliary roller 314. The second servo motor 307 drives the bidirectional lead screw 308 to rotate, causing the first support arm 309 and the second support arm 311 to move towards or away from each other along the dovetail groove of the transverse slide rail 305, thereby driving the tire pressure roller 310 to apply uniform pressure to the tire edge. The auxiliary roller 314 simultaneously supports the inner side of the tire. The two work together to complete the initial positioning and edge pressing of the tire, improving the contact accuracy.

[0043] Meanwhile, the auxiliary component 3, through a height adjustment structure consisting of a sliding sleeve housing 301, a one-way lead screw 303, and a first servo motor 304, can adjust the vertical height of the entire auxiliary component 3 according to the size difference of the wheel hub body 2. The first servo motor 304 drives the one-way lead screw 303 to rotate, causing the internal threaded slide rod 302 to slide up and down, thus adapting to different wheel hub specifications. In addition, the auxiliary roller 314, through the elastic connection structure of the limiting post 313 and the spring 316, can adaptively float with the undulations of the tire surface. It can maintain stable contact with the tire through the elastic force of the spring 316, and avoid damage caused by rigid compression, ensuring uniform pressure and flexible controllability during installation. The auxiliary component 3, through the combination of mechanical transmission and elastic support, achieves precise assistance in tire installation, effectively improving installation efficiency and quality, and reducing the difficulty of manual operation.

[0044] The implementation principle of an auxiliary installation device for tire and wheel hub in automobile production according to an embodiment of this application is as follows:

[0045] First, wheel hub positioning and component initialization: The wheel hub body 2 is placed on the base 1 and fixed. After the equipment is started, the auxiliary component 3 drives the one-way screw 303 through the first servo motor 304 in the sliding sleeve housing 301, so that the internal threaded slide bar 302 drives the entire auxiliary component 3 to the initial height, ensuring that the tire pressure roller 310 and the auxiliary roller 314 are aligned with the top of the wheel hub, and preparing for subsequent operations.

[0046] Secondly, height adaptive adjustment: According to the specifications of the tire to be installed, the first servo motor 304 drives the one-way lead screw 303 to rotate again, and the internal thread slide rod 302 slides up and down along the sleeve housing 301 to precisely adjust the vertical height of the auxiliary component 3, so that the position of the tire pressure roller 310 and the auxiliary roller 314 matches the height of the mounting surface of the wheel hub body 2, adapting to wheel hubs of different sizes.

[0047] Next, lateral symmetrical movement and positioning: the second servo motor 307 starts and drives the bidirectional lead screw 308 to rotate. Since the first support arm 309 and the second support arm 311 are respectively threaded onto the two ends of the bidirectional lead screw 308, the two move symmetrically towards each other along the dovetail groove of the lateral slide rail 305, driving the tire pressure roller 310 and the auxiliary roller 314 to approach the wheel hub body 2 synchronously until the rollers contact the tire edge and inner side, completing the initial positioning.

[0048] Next, flexible pressing and dynamic adaptation: the tire pressing roller 310 applies uniform pressure to the tire edge, while the auxiliary roller 314 adheres to the inner side of the tire through the bearing at the bottom of the limiting post 313. At this time, the spring 316 between the limiting ring 315 on the limiting post 313 and the limiting plate 312 provides elastic buffering, allowing the auxiliary roller 314 to float adaptively with the undulations of the tire surface. This maintains stable contact pressure while avoiding rigid compression that could damage the tire, ensuring that the pressing process is uniform and flexible.

[0049] Finally, the reset and cycle operation: after the tire and rim are fully in contact, the second servo motor 307 drives the bidirectional lead screw 308 in the reverse direction, so that the tire pressure roller 310 and the auxiliary roller 314 move symmetrically away from the rim. The first servo motor 304 drives the auxiliary component 3 to reset to the initial height, completing one installation process and waiting for the next set of rim and tire installation tasks.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
