Description

Technical Field

[0001] This utility model relates to the technical field of tire rim pressing devices, specifically an adjustable tire rim pressing equipment. Background Technology

[0002] Wheels are an important component of a car's driving system. They are in direct contact with the ground and play crucial roles such as supporting the car body, transmitting driving and braking forces, and cushioning road impacts.

[0003] Currently, pressing equipment is required to press tire rims during wheel assembly. However, commonly used pressing devices cannot press tire rims of different sizes, and the tire and rim experience severe friction during pressing, which can easily lead to poor sealing. For example, CN115782465A discloses a locking rim tire assembly device, which includes a frame, a tire support plate for supporting the tire, and a lower mounting plate located below the tire support plate; a rim lifting device, which includes a rim positioning ring for positioning the rim and a lifting actuator mounted on the lower mounting plate for lifting the rim positioning ring.

[0004] As can be seen from the above-mentioned disclosed scheme, the pressing equipment can only assemble tire rims of fixed size when in use, which limits its applicable scope. However, using a commonly used tire changer to disassemble and assemble the tire will cause wear on the rim groove, which in turn will result in poor sealing at the tire rim seal. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable tire rim pressing device to solve the problems of limited applicability and poor sealing after pressing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable tire rim pressing device, comprising a pressing device body, the pressing device body including a worktable, a positioning column fixedly connected to the surface of the worktable, a rim slidably connected to the surface of the positioning column, the bottom of the rim movably connected to the surface of the worktable, a pressing mechanism fixedly connected to the surface of the worktable, the pressing mechanism including a guide column, the bottom of the guide column fixedly connected to the surface of the worktable, a sliding groove opened on the side of the guide column, a lifting arm slidably connected to the inner wall of the sliding groove, a rotating component provided at one end of the lifting arm, an adjusting mechanism fixedly connected to the bottom of the rotating component, and a pressing block fixedly connected to the bottom of the adjusting mechanism. Through the provided adjusting seat, adjusting screw, adjusting block, and pressing rod, the horizontal movement position of the pressing block can be adjusted, thereby facilitating the pressing block to press tire rims of different sizes, increasing the applicability of the pressing device. Furthermore, through the provided rotary motor and turntable, the pressing block can avoid contact and wear with the rim groove, ensuring the sealing performance of the pressed tire rim.

[0007] Preferably, one end of the guide post is fastened to the top plate by screws, and a lifting motor is fixedly installed on the surface of the top plate. The output end of the lifting motor is fixedly connected to a lifting screw, and the surface of the lifting screw is threadedly connected to the surface of the lifting arm. The lifting screw can precisely control the lifting height of the lifting arm through the thread, avoiding excessive compression of the tire by the pressing block.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a technical solution: an adjustable tire rim pressing device, including a pressing device body 1. The pressing device body 1 includes a worktable 13, and a positioning post 11 is fixedly connected to the surface of the worktable 13. One end of the positioning post 11 is provided with a tapered part, which facilitates insertion into the center hole of the rim 12, allowing for quick positioning of the rim 12. The rim 12 is slidably connected to the surface of the positioning post 11, and the bottom of the rim 12 is movably connected to the surface of the worktable 13. A pressing mechanism 2 is fixedly connected to the surface of the worktable 13. The pressing mechanism 2 can press down on the tire bead portion by applying downward pressure, thereby deforming it and pressing it into the rim groove, thus completing the pressing of the rim 12 and the tire. The pressing mechanism 2 includes a guide post 21, which is used to adjust the downward pressing position of the pressing block 4, while avoiding excessive compression of the tire. The tire is damaged, and manual pressing is not required, reducing the labor intensity of the user. The bottom of the guide post 21 is fixedly connected to the surface of the workbench 13. The side of the guide post 21 has a sliding groove 22. One end of the lifting arm 26 is T-shaped and is slidably connected to the inner wall of the sliding groove 22, which can ensure the stability of the lifting position of the lifting arm 26. The inner wall of the sliding groove 22 is slidably connected to the lifting arm 26. One end of the lifting arm 26 is provided with a rotating component. The rotating component can drive the pressing block 4 to rotate and squeeze the tire. The bottom of the rotating component is fixedly connected to the adjustment mechanism 3. The adjustment mechanism 3 is used to adjust the distance between the pressing block 4 and the positioning post 11, so as to press the rims 12 and tires of different sizes. The bottom of the adjustment mechanism 3 is fixedly connected to the pressing block 4. The top of the pressing block 4 is fixedly connected to one end of the pressing rod 39. The pressing block 4 is used to squeeze the tire downward.

[0018] One end of the guide post 21 is fastened to the top plate 23 by screws. A lifting motor 24 is fixedly installed on the surface of the top plate 23. A lifting screw 25 is fixedly connected to the output end of the lifting motor 24. The surface of the lifting screw 25 is threadedly connected to the surface of the lifting arm 26. The lifting screw 25 can precisely control the lifting height of the lifting arm 26 through the thread, avoiding excessive compression of the tire by the pressing block 4. The rotating component includes a rotating motor 27. One end of the rotating motor 27 is fixedly connected to the surface of the lifting arm 26. A rotating shaft is fixedly connected to the output end of the rotating motor 27. A turntable 28 is fixedly connected to one end of the rotating shaft. The rotating motor 27 is interlocked with the lifting motor 24 to ensure that the pressing block 4 starts rotating after being pressed down to the set height. The turntable 28 can drive the pressing block 4 to rotate, thereby causing the pressing block 4 to rotate and compress the tire once, so that the tire bead is completely inserted into the rim groove.

[0019] The adjustment mechanism 3 includes an adjustment seat 31, the surface of which is fixedly connected to the bottom of the turntable 28. An adjustment groove 32 is opened at the bottom of the adjustment seat 31, and an adjustment screw 34 is rotatably connected to the inner wall of the adjustment groove 32. The adjustment screw 34 can adjust the position of the pressing block 4 by thread, which not only avoids the pressing block 4 from contacting the rim groove, but also facilitates pressing of tire rims 12 of different sizes. A rotating wheel 35 is fixedly connected to one end of the adjustment screw 34, and an adjustment block 36 is threadedly connected to the surface of the adjustment screw 34. A pressing rod 39 is fixedly connected to the bottom of the adjustment block 36. The surface of the adjustment block 36 is slidably connected to the inner wall of the adjustment groove 32, which ensures the rotational stability of the pressing rod 39.

[0020] The side of the adjusting block 36 is fixedly connected with symmetrical limiting rods 37. The surface of the limiting rods 37 is slidably connected with guide grooves 33. The limiting rods 37 achieve bidirectional locking through the guide grooves 33. The surface of the limiting rods 37 is threadedly connected with fastening knobs 38. The limiting rods 37 and fastening knobs 38 can lock the adjustment position of the adjusting block 36 to prevent the adjusting block 36 from moving arbitrarily. The two sides of the pressing block 4 are provided with first arc-shaped edges 42 and second arc-shaped edges 43. The bottom of the pressing block 4 is provided with an arc-shaped bottom 41. The arc-shaped bottom 41, the first arc-shaped edges 42 and the second arc-shaped edges 43 can reduce the wear of the pressing block 4 on the tire.

[0021] The working principle of this device is as follows: First, place the wheel rim 12 on the surface of the workbench 13, ensuring the positioning pin 11 is inserted upwards into the center hole of the wheel rim 12 to prevent it from sliding on the workbench 13. Then, place the tire downwards onto the wheel rim 12. Next, rotate the adjusting screw 34 counterclockwise to move the pressing rod 39 to the right, increasing the distance between the pressing block 4 and the positioning pin 11. Stop rotating the adjusting screw 34 once the pressing block 4 has moved to the right and is no longer directly above the outer edge of the wheel rim 12. Finally, manually tighten the screw clockwise. Turn knob 38, then start the lifting motor 24, causing the lifting screw 25 to rotate clockwise, which in turn drives the lifting arm 26 to move downward. The downward movement of the lifting arm 26 causes the pressing block 4 to press down on the tire bead position, causing the pressed position to deform downward and get stuck in the rim groove of the rim 12. Then stop the lifting motor 24, and then start the rotary motor 27. The rotary motor 27 drives the turntable 28 to rotate. The rotation of the turntable 28 causes the pressing block 4 to rotate along the tire and press the tire bead, so that the entire tire bead is completely stuck in the rim groove, completing the pressing of the rim 12 and the tire.
