Description

Technical Field

[0001] This utility model relates to the field of automobile tire assembly technology, and more specifically, to a tire mounting and positioning device. Background Technology

[0002] Tire mounting and positioning equipment is a device used to assist in the handling and installation of tires. It typically consists of a robotic arm, grippers, and a movable base. The robotic arm can extend and rotate flexibly, the grippers can firmly hold the tire, and the movable base allows the device to be moved to different positions. This device reduces the labor intensity of manual tire handling and installation, improves work efficiency, and also reduces errors and safety accidents that may be caused by manual operation.

The base assembly includes a base and a first slide rail and a second slide rail vertically fixed on the base. The fork arm assembly includes a sliding frame and a first fork arm and a second fork arm connected to the same side of the sliding frame. The sliding frame is slidably connected to the first slide rail and the second slide rail. The first fork arm and the second fork arm are located at the same height and are parallel and spaced apart. The first fork arm and the second fork arm are used to place the tire to be installed. The lifting drive device is used to drive the sliding frame to slide up and down along the first slide rail and the second slide rail. The tire mounting and lifting device provided by this utility model can maintain a vertical, non-compressed state when the tire to be installed is placed on the first fork arm and the second fork arm, and can then freely rotate and adjust the position of the tire to be installed until the bolt holes on the tire are aligned with the bolts on the wheel hub.

[0004] However, this tire lifting device has the following drawbacks: it can only move and lift tires, and cannot position and fix tires of different sizes, which affects work efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tire mounting and positioning device to solve the problem that the prior art can only move and lift tires, but cannot position and fix tires of different specifications.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a tire mounting and positioning device, comprising...

[0007] The bracket has a hydraulic cylinder fixedly connected to its exterior. A top plate is fixedly connected to the drive end of the hydraulic cylinder. Two pull plates are movably connected to the exterior of the top plate. A connecting plate is movably connected to the end of each pull plate away from the top plate. A fixing rod is fixedly connected to the inner wall of the connecting plate. A rotating rod is rotatably connected to the inner wall of the connecting plate. A slider is fixedly connected to the exterior of the connecting plate. Two fixing columns are fixedly connected to the exterior of the bracket. An adjustment assembly for adjusting subsequent components is slidably connected to the inner wall of the fixing columns.

[0008] The adjusting assembly includes an adjusting rod, with two slide bars slidably connected to the inner wall of the adjusting rod. Each slide bar has a pressure plate slidably connected to its inner wall. A pressure column is fixedly connected to one end of each pressure plate, and a spring is fixedly connected to the end of each pressure plate away from the pressure column. A fixing block is fixedly connected to the outside of the adjusting rod. A support rod is rotatably connected to the inner wall of the fixing block. A support block is fixedly connected to the end of the support rod away from the fixing block. Sliding plates are fixedly connected to both ends of the support block. A spring is fixedly connected to the end of each sliding plate away from the support block. A cone is slidably connected to the outside of the sliding plate. A cone is movably connected to the outside of the cone. A washer is fixedly connected to the outside of the cone.

[0009] The gasket is fixedly connected to the outside of the cone, and the support block is slidably connected to the inner wall of the gasket.

[0010] The outer side of the sliding plate is slidably connected to the inner wall of the gasket, and one end of the spring away from the pressure plate is fixedly connected to the inner wall of the adjusting rod.

[0011] The pressure column is slidably connected to the inner wall of the slide bar, and the outer side of the connecting plate is in contact with the outer side of the bracket.

[0012] The fixed rod is slidably connected to the inner wall of the bracket, and the rotating rod is slidably connected to the inner wall of the bracket.

[0013] The slider is slidably connected to the inner wall of the bracket, and the fixing rod is fixedly connected to the outside of the slider.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, the car tire is placed between two rotating rods, and then the hydraulic cylinder is activated to push the top plate upward. The top plate pulls the connecting plate through the connected pull plate, causing the connecting plate to move in the direction of the hydraulic cylinder. As the connecting plate moves horizontally, it also drives the fixed rod and the rotating rod to move. During the movement, the two rotating rods will squeeze the tire. Since the rotating rods will rotate when they contact the tire, the tire will move to the top of the rotating rods. This can push the tire and improve work efficiency.

[0016] In the above solution, by setting an adjustment component, pinching the two sliders causes the sliders, along with a pair of springs, to press against the pressure plate in the pressure column. Since the pressure column is inside the two sliders, the springs deform to allow the sliders to move. At this point, the sliders are no longer locked inside the fixed column, and the adjustment rod can be moved to position them according to the center hole of the car tire. During positioning, cone one and cone two are locked in the center hole of the tire. Since cone one and the shim together form a cone shape, and because cone two and cone one are opened by the pressure of the spring on the support block, cone two and cone one are fixed when they enter the center hole. The shim increases the friction to achieve a tight fit during fixing, improving stability during tire installation. Attached Figure Description

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] As attached Figure 1 To be continued Figure 5 An embodiment of this utility model provides a tire mounting and positioning device, including...

[0026] Support frame 1 serves as the fundamental support structure for the entire equipment, ensuring its overall stability. A hydraulic cylinder 2 is externally fixed to support frame 1. The hydraulic cylinder 2 is a crucial component for power output, generating thrust or pull force through hydraulic pressure. A top plate 3 is fixedly connected to the drive end of the hydraulic cylinder 2. When the hydraulic cylinder 2 operates, the extension and retraction of its drive end causes the top plate 3 to move accordingly, thus controlling its position. Two pull plates 4 are externally movably connected to the top plate 3. Power is transmitted through the pull plates 4 as the top plate 3 moves. This movable connection between the pull plates 4 and the top plate 3 allows for relative movement within a certain range, ensuring flexible power transmission. A connecting plate 5 is movably connected to the end of each pull plate 4 furthest from the top plate 3. The pull plates 4 transmit power to the connecting plates 5, which move under the influence of the pull plates 4. This movable connection also ensures the flexibility and adjustability of the connecting plates 5.

[0027] A fixing rod 6 is fixedly connected to the inner wall of the connecting plate 5. The fixing rod 6 is fixed to the inner wall of the connecting plate 5, providing a certain connection and fixation function, ensuring a relatively stable positional relationship between the connecting plate 5 and other components. A rotating rod 7 is rotatably connected to the inner wall of the connecting plate 5. The rotating rod 7 rotates within the inner wall of the connecting plate 5. This structure is a key component for compressing and pushing the tire. When the rotating rod 7 contacts the tire, it rotates, thereby moving the tire. A slider 8 is fixedly connected to the outside of the connecting plate 5. The slider 8 provides guidance and support for the movement of the connecting plate 5, allowing the connecting plate 5 to slide along the support 1 in a specific direction, ensuring the stability and accuracy of the movement. Two fixing columns 9 are fixedly connected to the outside of the support 1. The fixing columns 9 provide installation and fixing positions for subsequent adjustment components and cooperate with the adjustment components to realize the adjustment function of the equipment.

[0028] The adjustment assembly includes an adjustment rod 10, which is the main component of the assembly. Its movement adjusts the position of the equipment to accommodate different tire installation requirements. Two slide bars 11 are slidably connected to the inner wall of the adjustment rod 10. These slide bars 11 allow for positional adjustment within the adjustment rod 10. Pressure plates 12 are slidably connected to the inner walls of both slide bars 11. These pressure plates 12, in cooperation with the slide bars 11, control and adjust the pressure column 13, thereby affecting the equipment's tire positioning and installation. A pressure column 13 is fixedly connected to a nearby end of the pressure plate 12. The pressure column 13 moves under the influence of the pressure plate 12, adjusting the engagement between the slide bars 11 and the fixed column 9, thus controlling the movement of the adjustment rod 10. A spring 14 is fixedly connected to the end of the pressure plate 12 away from the pressure column 13. The spring 14 will deform when the pressure plate 12 moves. Its function is to provide a certain elastic force to the pressure plate 12 so that the pressure plate 12 can return to its original position after being subjected to external force, thus ensuring the accuracy and stability of adjustment.

[0029] A fixing block 15 is fixedly connected to the outside of the adjusting rod 10. The fixing block 15 is fixed to the outside of the adjusting rod 10, providing a fixed connection point for the support rod 16, so that the support rod 16 can be stably connected to the adjusting rod 10. The support rod 16 is rotatably connected to the inner wall of the fixing block 15. The support rod 16 rotates on the inner wall of the fixing block 15. This rotatable connection allows the support rod 16 to be adjusted in angle according to actual conditions during operation to adapt to different working requirements. A support block 17 is fixedly connected to the end of the support rod 16 away from the fixing block 15. The support block 17 moves under the drive of the support rod 16. It is an important component connecting cone 1 20 and cone 2 21, and plays a supporting and force-transmitting role. Sliding plates 18 are fixedly connected to both ends of the support block 17. The sliding plates 18 slide on the inner wall of the gasket 22, providing guidance and support for the movement of the support block 17, ensuring the stability and accuracy of the movement of the support block 17.

[0030] A spring 19 is fixedly connected to the end of the sliding plate 18 away from the support block 17. The spring 19 deforms when the sliding plate 18 moves, and its elastic force keeps cones 20 and 21 open, thus fixing the tire's center hole. Cone 20 is slidably connected to the outside of the sliding plate 18. Cone 20 moves under the drive of the sliding plate 18 and cooperates with cone 21 to lock into the tire's center hole, achieving tire positioning. Cone 21 is movably connected to the outside of cone 20. Their relative movement allows for opening and closing actions to adapt to different tire center hole sizes and shapes. A washer 22 is fixedly connected to the outside of cone 21. The washer 22 increases the friction between cone 21 and the tire's center hole, allowing cones 20 and 21 to fit more tightly when fixing the tire, improving stability.

[0031] The gasket 22 is externally fixed to the outside of cone 20. This connection allows the gasket 22, cone 20, and cone 21 to form a stable integral structure, working together to fix the tire. The support block 17 is externally slidably connected to the inner wall of the gasket 22. The sliding of the support block 17 on the inner wall of the gasket 22 can drive cone 20 and cone 21 to move, thereby achieving the positioning and fixation of the tire center hole.

[0032] The sliding plate 18 is externally slidably connected to the inner wall of the pad 22. The sliding of the sliding plate 18 on the inner wall of the pad 22 provides guidance and support for the movement of the support block 17, ensuring the accuracy and stability of the movement of cone 1 20 and cone 2 21. The end of the spring 14 away from the pressure plate 12 is fixedly connected to the inner wall of the adjusting rod 10. This connection method allows the spring 14 to provide elastic force when the pressure plate 12 moves, ensuring that the pressure plate 12 can return to its original position, thereby achieving stable control of the engagement relationship between the slide bar 11 and the fixed post 9.

[0033] The pressure column 13 is externally slidably connected to the inner wall of the slide bar 11. The sliding of the pressure column 13 on the inner wall of the slide bar 11 allows the pressure plate 12 to press and adjust the slide bar 11 through the pressure column 13, thereby controlling the engagement relationship between the slide bar 11 and the fixed column 9. The outer side of the connecting plate 5 is in contact with the outer side of the bracket 1. This contact relationship allows the connecting plate 5 to slide along the outer side of the bracket 1 when moving, ensuring the stability and accuracy of the movement of the connecting plate 5.

[0034] The fixed rod 6 is externally slidably connected to the inner wall of the bracket 1. The sliding of the fixed rod 6 on the inner wall of the bracket 1 provides guidance and support for the movement of the connecting plate 5, enabling the connecting plate 5 to maintain a relatively stable position during movement. The rotating rod 7 is externally slidably connected to the inner wall of the bracket 1. The sliding of the rotating rod 7 on the inner wall of the bracket 1 ensures that the rotating rod 7 can work stably when squeezing and pushing the tire, and also allows the position of the rotating rod 7 to be adjusted according to actual needs.

[0035] The slider 8 is externally slidably connected to the inner wall of the bracket 1. The sliding of the slider 8 on the inner wall of the bracket 1 provides stable guidance and support for the movement of the connecting plate 5, enabling the connecting plate 5 to move accurately on the bracket 1 along a specific direction. The fixing rod 6 is externally fixedly connected to the outside of the slider 8. This connection method allows the fixing rod 6 and the slider 8 to form a stable integral structure, working together when the connecting plate 5 moves to ensure the stability and accuracy of the movement of the connecting plate 5.

[0036] The working process of this utility model is as follows:

[0037] First, by placing the car tire between the two rotating rods 7, the hydraulic cylinder 2 is activated to push the top plate 3 upward. The top plate 3 pulls the connecting plate 5 through the connected pull plate 4, causing the connecting plate 5 to move in the direction of the hydraulic cylinder 2. As the connecting plate 5 moves horizontally, it also drives the fixed rod 6 and the rotating rod 7 to move. During the movement, the two rotating rods 7 will squeeze the tire. Since the rotating rod 7 will rotate when it contacts the tire, the tire will move above the rotating rod 7. This pushes the tire and improves work efficiency.

[0038] By pinching the two sliders 11, the sliders 11, along with the spring 14, press the pressure plate 12 connected to the pressure column 13. Since the pressure column 13 is inside the two sliders 11, the spring 14 deforms to allow the two sliders 11 to move. At this time, the sliders 11 are no longer locked inside the fixing column 9, and can be positioned according to the center hole of the car tire by moving the adjusting rod 10. During positioning, cone 1 20 and cone 21 are locked in the center hole of the tire. Since the shape of cone 1 20 and the pad 22 is a cone, and because cone 21 and cone 1 20 are opened by the spring 29 pressing the support block 17, cone 21 and cone 21 are fixed when they enter the center hole. The pad 22 increases the friction to achieve a tight fit during fixing, which improves the stability during the tire rotation process.
