[0047] Reference Figure 1 and Figure 3 As shown, an auxiliary tooling for tire assembly according to an embodiment of the present invention includes: a feeding mechanism 100, a swinging mechanism 300, a rotating mechanism 400, and a mounting part 500.

[0048] The feeding mechanism 100 is used to support the wheel hub 200.

[0049] The swing mechanism 300 includes a swing arm 310 and a first drive unit 320. The swing arm 310 is rotatably disposed around a first axis, and the first drive unit 320 is connected to the swing arm 310 for driving the swing arm 310 to rotate around the first axis.

[0050] The rotating mechanism 400 includes a rotating part 410 and a second driving part 420. The rotating part 410 is rotatably connected to the end of the swing arm 310 away from the first axis about a second axis. The second driving part 420 is connected to the rotating part 410 and is used to drive the rotating part 410 to rotate about the second axis relative to the swing arm 310.

[0051] The mounting part 500 is connected to the rotating part 410. The mounting part 500 can rotate synchronously with the rotating part 410. The mounting part 500 is provided with a connection structure for connecting the hub 200.

[0052] The first drive unit 320 can drive the swing arm 310 to rotate to the loading position. When the swing arm 310 is in the loading position, such as Figure 1 and Figure 2 The mounting part 500 is connected to the feeding mechanism 100 so that the mounting part 500 can be connected to the wheel hub 200 supported on the feeding mechanism 100 via a connecting structure. Furthermore, after the wheel hub 200 is mounted on the mounting part 500, the first drive part 320 can drive the swing arm 310 to rotate so that the wheel hub 200 is separated from the feeding mechanism 100 by a certain distance, facilitating the installation of the rubber ring. After the wheel hub 200 is detached from the feeding mechanism 100, the feeding mechanism 100 can be used to support the rubber ring.

[0053] In this embodiment of the auxiliary tooling for tire assembly, the first drive unit 320 drives the swing arm 310 to rotate until it aligns with the loading mechanism 100. Then, the wheel hub 200 is loaded onto the loading mechanism 100, aligning the connection structure between the wheel hub 200 and the mounting part 500. The mounting part 500 and the wheel hub 200 are connected via the connection structure. Then, the first drive unit 320 drives the swing arm 310 to rotate, causing the wheel hub 200 mounted on the mounting part 500 to move a certain distance away from the loading mechanism 100. Leave space for the rubber ring, then activate the second drive unit 420 to drive the rotating unit 410 to rotate slowly, causing the wheel hub 200 to rotate slowly. The rubber ring is then fed onto the feeding mechanism 100 and placed at an angle onto the wheel hub 200. As the wheel hub 200 rotates slowly, the rubber ring is slowly assembled onto it. After assembly, the swing arm 310 is rotated again to align with the feeding mechanism 100, and the wheel hub 200 is then removed from the mounting part 500. This structural design not only makes operation convenient but also ensures high assembly efficiency by using rotation to connect the wheel hub 200 and the rubber ring.

[0054] In some embodiments of this utility model, such as Figure 1 As shown, the auxiliary tooling for tire assembly also includes a fixed frame 800, a swing arm 310 rotatably mounted on the fixed frame 800 about a first axis, and a first drive unit 320 connected between the fixed frame 800 and the swing arm 310. It is conceivable that the first drive unit 320 can be a pneumatic cylinder or a hydraulic cylinder.

[0055] Based on the above embodiments, it is conceivable that the first axis may be parallel to the second axis or may not be parallel. In this embodiment, the first axis and the second axis are parallel and both extend horizontally.

[0056] Reference Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the connection structure includes a plurality of connection holes 501, which are evenly arranged around the second axis. At least some of the connection holes 501 are used to align with the bolt holes 201 of the hub 200 and install the bolt assembly 600 to fix the hub 200 to the mounting part 500. Obviously, after the hub 200 is installed on the mounting part 500, the center line of the hub 200 is collinear with the second axis, that is, when the rotating part 410 rotates, it can drive the hub 200 to rotate around its own axis.

[0057] In this embodiment, by providing connection holes 501, the existing structure (bolt holes 201) of the wheel hub 200 can be used to connect the mounting part 500 (mounting bolt assembly 600), while ensuring the stability and reliability of the connection. In addition, by providing multiple connection holes 501, it can be adapted to the installation of wheel hubs 200 of various specifications (the size of the distribution circle of bolt holes 201 on wheel hubs of different specifications must remain unchanged).

[0058] It is understandable that the position of the feeding mechanism 100 should satisfy the following: when the swing arm 310 is in the feeding position, after the hub 200 is fed onto the feeding mechanism 100, the hub 200 can adjust its posture so that at least two bolt holes 201 on it are aligned with at least two connection holes 501 on the mounting part 500.

[0059] Understandably, without compromising structural strength, the number of connecting holes 501 should be as large as possible to accommodate more wheel hubs 200.

[0060] Understandably, bolt assembly 600 includes bolts, nuts, and washers.

[0061] Reference Figure 1 and Figure 3 As shown, in some embodiments of this utility model, the feeding mechanism 100 includes a base 110 and a plurality of support rollers 120. The plurality of support rollers 120 are arranged horizontally side by side, and their arrangement direction is perpendicular to the second axis; the support rollers 120 are rotatably mounted on the base 110, the rotation axis of the support rollers 120 is parallel to the second axis, and the support rollers 120 protrude upward from the base 110 to support the hub 200.

[0062] In this embodiment, by rotating the support roller 120, after the swing arm 310 is rotated to the loading position, the hub 200 can be placed on the support roller 120. By rotating the hub 200, the bolt holes 201 on the hub 200 are aligned with the connecting holes 501 on the mounting part 500, thereby improving the convenience of operation.

[0063] Reference Figure 3 As shown, in some embodiments of this utility model, the feeding mechanism 100 further includes a guide portion 130. The guide portion 130 is fixed to one side of the base 110 along the arrangement direction of the plurality of support rollers 120. The upper end of the guide portion 130 has a guide surface 131. The guide surface 131 extends downward from the top of the base 110 away from the base 110, so that when the hub 200 is fed onto the support rollers 120, it can be guided by the guide surface 131, thereby reducing labor intensity.

[0064] Reference Figure 3 and Figure 4As shown, in some embodiments of the present invention, the rotating part 410 includes a rotating shaft 412 and a turntable 413. The rotating shaft 412 is rotatably connected to the swing arm 310 and connected to the second drive part 420. The axis of the rotating shaft 412 is collinear with the second axis. The turntable 413 is coaxially fixed to the end of the rotating shaft 412 away from the swing arm 310.

[0065] It is conceivable that the second drive unit 420 could be a geared motor that directly drives the rotating shaft 412 to rotate. Of course, the second drive unit 420 could also be a structure consisting of a motor plus a gear transmission mechanism, a belt transmission mechanism, or a chain transmission mechanism. These are conventional technical means, so they will not be elaborated on here.

[0066] Reference Figures 4 to 6 As shown, in some embodiments of this utility model, the turntable 413 is provided with a mounting hole 411 extending parallel to the second axis, and the mounting hole 411 is through-hole; the mounting part 500 includes a mounting plate 510 and a mounting post 520. The mounting plate 510 is provided with the above-mentioned connection structure, that is, a connecting hole 501 is provided on the mounting plate 510, the mounting plate 510 is attached to the turntable 413, the mounting post 520 extends parallel to the second axis, the mounting post 520 is fixed to the side of the mounting plate 510 facing the turntable 413, and passes through the mounting hole 411, and is installed through the mounting hole 411. The mounting post 520 is engaged with the mounting hole 411 to radially limit the mounting portion 500 relative to the turntable 413. The mounting post 520 is provided with a locking hole 521 extending perpendicular to the second axis. The locking hole 521 is located on the side of the turntable 413 away from the mounting plate 510. A locking mechanism 700 is mounted on the turntable 413. The locking mechanism 700 is partially inserted into the locking hole 521 to axially limit the mounting portion 500 relative to the turntable 413, thereby fixing the mounting portion 500 to the turntable 413. In addition, the locking mechanism 700 can be adjusted to be separated from the locking hole 521.

[0067] In this embodiment, the above-described structure is used to achieve a detachable connection between the mounting part 500 and the rotating part 410, thereby facilitating the replacement of the mounting part 500; and further facilitating the replacement of mounting parts 500 of different specifications (the distribution circle size of the multiple connecting holes 501 of different specifications of mounting parts 500 is different) to adapt to the installation of more specifications of wheel hubs 200.

[0068] It is conceivable that multiple sets of mounting holes 411, mounting posts 520, and locking mechanisms 700 can be provided.

[0069] Reference Figures 4 to 6As shown, in some embodiments of this utility model, the locking mechanism 700 includes a locking rod 710 and an elastic part 720. The locking rod 710 is slidably mounted on the turntable 413 in a direction perpendicular to the second axis, and the locking rod 710 is used to partially insert into the locking hole 521; the elastic part 720 is disposed between the turntable 413 and the locking rod 710, and is used to apply an elastic force toward the locking hole 521 to the locking rod 710, and the elastic force is distributed perpendicular to the second axis. By adopting the above-described structure, the disassembly and assembly of the mounting part 500 can be made more convenient. When it is necessary to disassemble the mounting part 500, simply pull the locking rod 710 to move it against the elastic force of the elastic element until it is separated from the locking hole 521, and then the mounting part 500 can be removed from the turntable 413 of the rotating part 410.

[0070] Reference Figures 4 to 6 As shown, in some embodiments of this utility model, a mounting base 430 is fixedly provided on the turntable 413. The mounting base 430 is used to slide the locking rod 710. The locking rod 710 has a boss 711 at the middle of its length direction. The boss 711 is located on the side of the mounting base 430 near the locking hole 521. The elastic part 720 is set as a compression spring. The compression spring is sleeved on the locking rod 710. The compression spring is located on the side of the boss 711 away from the locking hole 521, and its two ends abut against the boss 711 and the mounting base 430 respectively. The structure is stable and reliable.

[0071] Reference Figures 4 to 6 As shown, in some embodiments of this utility model, the mounting base 430 defines a mounting cavity 431, and the boss 711 and the compression spring are both located within the mounting cavity 431. On the one hand, the mounting cavity 431 can provide a certain radial limit for the boss 711, improving the reliability of the installation of the locking rod 710. On the other hand, it can also reduce the contact between the compression spring and the external environment, improving its service life. It is understood that the mounting cavity 431 is opened on the side near the locking hole 521, and the mounting base 430 is provided with a through hole on the side of the mounting cavity 431 away from the locking hole 521 for the locking rod 710 to pass through.

[0072] In some specific embodiments, the mounting base 430 is configured as a cylindrical structure.

The pull plate 730 is configured to be operable to move the locking rod 710 away from the locking hole 521, thereby facilitating the operator to pull the locking rod 710.

[0074] In some specific embodiments, refer to Figures 4 to 6As shown, the pull plate 730 has a sleeve hole for fitting onto the locking rod 710. The locking rod 710 is threadedly connected to a limit nut 740 on the side of the pull plate 730 away from the mounting base 430. In a further embodiment, two mounting holes 411, two mounting posts 520, and two locking mechanisms 700 are provided. The two locking mechanisms 700 are arranged in parallel, that is, the locking rods 710 of the two locking mechanisms 700 are distributed in parallel. In addition, the two locking rods 710 are connected to a pull plate 730 at the same time, so that the operator can pull the pull plate 730 to move the two locking mechanisms 700 simultaneously to lock the mounting part 500, which is very convenient to operate.

[0075] Reference Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the mounting portion 500 is provided with a protective pad 530 for contacting the side of the hub 200. Specifically, the protective pad 530 is attached to the surface of the mounting plate 510 away from the mounting post 520, and the protective pad 530 has clearance holes corresponding one-to-one with the connection holes 501. Obviously, the protective pad 530 can be fixed to the mounting plate 510 with screws.
