Description

Technical Field

[0001] This utility model belongs to the field of tire assembly technology, specifically referring to a tire auxiliary assembly device. Background Technology

[0002] After the wheel is manufactured, it is assembled separately from the tire. Before the car is assembled, the tire and wheel need to be assembled first, and then the entire wheel is installed on the car.

[0003] Existing assembly methods mainly rely on multiple devices to complete the process. Typically, the wheel hub needs to be fixed first, and then the tires need to be assembled. Clamping and pressing need to be performed independently, and linkage operation cannot be achieved. The overall equipment occupies a large area and has low resource utilization. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a tire auxiliary assembly device, which effectively solves the problem that wheel hub locking and tire pressing cannot be completed simultaneously.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a tire auxiliary assembly device, including a support base, a support frame fixed on the support base, a placement platform at the center of the support base, and a limiting rod arranged at equal intervals around the placement platform on the support base, the limiting rod being vertical at the bottom and inclined outward at the top;

[0006] The support frame has a vertically mounted cylinder at its top. The output end of the cylinder is connected to a fixed frame. A top plate is fixed to the bottom of the fixed frame. L-shaped external frames are fixed to both sides of the top plate. A wedge-shaped push plate is installed at the bottom of the external frame. A connecting plate slides horizontally on the limiting rod. A clamping block is fixed to one end of the connecting plate, and a wedge-shaped push block is fixed to the other end. The inclined surface of the push block matches the inclined surface of the push plate.

[0007] Preferably, a horizontal bar is slidably passed through the limiting rod, one end of the horizontal bar is fixed to the pushing block, and a spring is sleeved on the horizontal bar, with both ends of the spring fixed to the pushing block and the limiting rod.

[0008] Preferably, the wedge-shaped inclined plane of the push plate and the push block has an inclination angle of 45-60°.

[0009] Preferably, a rotary motor is installed above the top plate, a rotating plate is fixedly connected to the output end of the rotary motor, and pressing wheels are installed around the bottom of the rotating plate.

[0010] Preferably, the side of the clamping block that contacts the wheel hub is provided with an anti-slip rubber layer.

[0011] Preferably, the pressing wheel is made of nylon and the rim width is greater than the tire bead thickness.

[0012] Preferably, the support base is provided with a receiving groove for the push plate to pass through.

[0013] The beneficial effects of the above-mentioned structure are as follows: the tire is initially limited by four sets of limiting rods with a vertical bottom and an inclined top. With the unique wedge-shaped push plate-push block structure, when the cylinder drives the top plate and the outer frame to move downward, the push plate squeezes the push block, and the push block drives the clamping block to quickly clamp and fix the wheel hub. At the same time, the cylinder drives the pressing wheel downward to squeeze the tire, thus completing the entire process of wheel hub fixing and tire assembly at the same time, improving the utilization rate of resources.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, the present invention proposes a tire auxiliary assembly device, including a support base 1, a support frame 2 fixed on the support base 1, a placement platform 3 at the center of the support base 1, and a limiting rod 4 evenly spaced around the placement platform 3 on the support base 1. The limiting rod 4 is vertical at the bottom and tilted outward at the top.

[0022] like Figure 1 , 2 As shown in Figure 4, the support frame 2 has a vertically mounted cylinder 5 at its top. The output end of the cylinder 5 is connected to a fixed frame 6. The bottom of the fixed frame 6 is fixed with a top plate 7. The top plate 7 has L-shaped external frames 8 fixed on both sides. The bottom of the external frames 8 is equipped with a wedge-shaped push plate 9. A connecting plate 10 slides horizontally on the limiting rod 4. One end of the connecting plate 10 is fixed with a clamping block 11, and the other end is fixed with a wedge-shaped push block 12. The inclined surface of the push block 12 matches the inclined surface of the push plate 9. The inclination angle between the wedge-shaped inclined surface of the push plate 9 and the push block 12 is 45-60°. The side of the clamping block 11 that contacts the wheel hub is provided with an anti-slip rubber layer to increase the stability of the clamping. The support base 1 is provided with a receiving groove 18 for the push plate 9 to pass through, providing a certain amount of movement space. A horizontal bar 13 slides horizontally through the limiting rod 4. One end of the horizontal bar 13 is fixed to the push block 12. A spring 14 is sleeved on the horizontal bar 13. The two ends of the spring 14 are fixed to the push block 12 and the limiting rod 4.

[0023] like Figure 1 , 2 As shown in Figure 4, a rotary motor 15 is installed above the top plate 7. A rotating plate 16 is fixedly connected to the output end of the rotary motor 15. Pressing rollers 17 are installed around the bottom of the rotating plate 16. The pressing rollers 17 are made of nylon, and their rim width is greater than the tire bead thickness, ensuring that the pressing rollers 17 completely cover and evenly press the tire bead area during assembly. This allows the tire to fit better with the rim, avoiding situations where some areas are not pressed properly or the pressing is uneven.

[0024] In practical use, place the wheel hub on the placement platform 3 of the device, ensuring that the wheel hub is in the center position of the four sets of limit rods 4. Place the tire steadily on the wheel hub, aligning the tire with the wheel hub. Activate cylinder 5, which drives the top plate 7, the fixing frame 6, and the outer frame 8 to move downwards. The push plate 9 at the bottom of the outer frame 8 also descends. As the push plate 9 descends, the wedge-shaped push plate 9 contacts the push block 12 and gradually squeezes the push block 12. The push block 12 slides horizontally under the guidance of the crossbar 13 and the connecting plate 10, driving the clamping block 11 to move towards the wheel hub. The clamping block 11 clamps the wheel hub tightly. During this process, the spring 14 is compressed, providing a certain amount of buffering and adaptive clamping force until the wheel hub is securely fixed.

[0025] After the wheel hub is fixed, continue to control cylinder 5 to move the top plate 7 and the rotary motor 15, rotating plate 16 and pressing wheel 17 mounted on the top plate 7 further downward until the pressing wheel 17 contacts the top of the tire. Start the rotary motor 15, which drives the rotating plate 16 and pressing wheel 17 to rotate. During the rotation, the pressing wheel 17 applies uniform pressure to the tire, pushing the tire to gradually fit tightly against the wheel hub, thus completing the assembly process.

[0026] After assembly, first turn off the rotary motor 15, then control the cylinder 5 to drive the top plate 7 and each component to rise and reset, loosen the clamping block 11, and take out the assembled tire and wheel hub.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
