Description

Technical Field

[0001] This utility model relates to the field of positioning mechanism technology, specifically a positioning mechanism for assembling automobile tires and wheel hubs. Background Technology

[0002] As we all know, a car wheel hub is a cylindrical metal component inside a car tire that supports the tire around its axle. In simple terms, it is the part of the wheel where the axle is mounted. When assembling and using a tire, the car wheel hub needs to be positioned and installed, usually through an assembly positioning mechanism.

[0003] Existing automotive tire and wheel hub assembly and positioning mechanisms have significant limitations: their core positioning components are mostly fixed connection structures, forming an inseparable whole with the main body of the equipment. When positioning wheel hubs of different sizes is required, the positioning mechanism cannot be flexibly disassembled and replaced according to the wheel hub specifications, and can only be adapted to a single or limited range of wheel hub models. This design makes it difficult for the equipment to match the positioning requirements of different sizes when facing diverse production needs, which seriously limits the applicability of the equipment and reduces its overall practicality and production flexibility.

[0005] To address the shortcomings of existing technologies, this utility model provides an automobile tire and wheel hub assembly and positioning mechanism.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism for assembling automobile tires and hubs, comprising a base plate, a positioning mechanism, and a body. The base plate has a support seat at its bottom, and several support seats are provided. The positioning mechanism includes a frame, a T-block, a square block, a T-slot, a cylinder, a circular plate, a limiting post, a threaded groove, a threaded rod, a limiting cylinder, a telescopic cylinder, a connecting plate, and a limiting frame. The top of the frame contacts the bottom of the base plate. One end of the T-block is connected to the frame. The T-slot is formed on the square block, and the other end of the T-block extends into the T-slot. The top of the square block is connected to the cylinder. One end of the cylinder is connected to the bottom plate, and the other end of the cylinder passes through the bottom plate. The circular plate is fixedly connected to the outer wall of the cylinder. One end of the limiting post is connected to the top of the bottom plate, and the other end of the limiting post is connected to the bottom of the circular plate. The body is disposed on the outer wall of the cylinder, and the bottom of the body contacts the top of the circular plate.

The output end of the telescopic cylinder is connected to one end of the connecting plate, and the other end of the connecting plate is connected to the limiting frame. One end of the limiting frame passes through the bottom plate and contacts the frame.

[0008] To improve the wear resistance, the present invention is improved by providing a wear-resistant layer at the bottom of the support base, and the wear-resistant layer is fixedly connected to the bottom of the support base.

[0021] 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.

[0022] Please see Figure 1-4 A positioning mechanism for assembling automobile tires and wheel hubs includes a base plate 1, a positioning mechanism 3, and a body 14. The base plate 1 has a support seat 2 at its bottom, and several support seats 2 are provided. The positioning mechanism 3 includes a frame 4, a T-block 5, a square block 6, a T-slot 7, a cylinder 8, a circular plate 9, a limiting post 10, a threaded groove 11, a threaded rod 12, a limiting cylinder 13, a telescopic cylinder 15, a connecting plate 16, and a limiting frame 17. The top of the frame 4 contacts the bottom of the base plate 1. One end of the T-block 5 is connected to the frame 4. The T-slot 7 is formed on the square block 6, and the other end of the T-block 5 extends into the T-slot 7. The top of the square block 6 is connected to one end of the cylinder 8, and the other end of the cylinder 8 extends into the T-slot 7. One end of the circular plate 9 passes through the base plate 1 and is fixedly connected to the outer wall of the cylindrical plate 8. One end of the limiting post 10 is connected to the top of the base plate 1 and the other end of the limiting post 10 is connected to the bottom of the circular plate 9. The body 14 is disposed on the outer wall of the cylindrical plate 8 and the bottom of the body 14 contacts the top of the circular plate 9. The threaded groove 11 is formed on the cylindrical plate 8. The threaded rod 12 is disposed on the limiting cylinder 13. The telescopic cylinder 15 is disposed on the side of the base plate 1. The output end of the telescopic cylinder 15 is connected to one end of the connecting plate 16 and the other end of the connecting plate 16 is connected to the limiting frame 17. One end of the limiting frame 17 passes through the base plate 1 and contacts the frame 4.

[0023] Working principle: After placing the equipment in the designated position, the support base 2 provides stable support for the overall structure. Then, the equipment is connected to the external mains power supply, and the equipment can be started by operating the controller 18 on the front of the base plate 1.

[0024] like Figure 1As shown, the worker first inserts the body 14, which matches the size of the cylinder 8, into the outer wall of the cylinder 8, so that the bottom of the body 14 fits against the top of the circular plate 9; then screws the threaded rod 12 into the threaded groove 11 of the cylinder 8, so that the limiting cylinder 13 moves down along the outer wall of the cylinder 8 until the bottom of the limiting cylinder 13 is in close contact with the top of the body 14, thereby completing the axial limiting of the body 14 and preventing it from moving up and down during the assembly process. At this time, the worker can carry out the subsequent assembly operation of the tire and the wheel hub based on this positioning state (the specific assembly steps are common knowledge in this field and will not be described here).

[0025] When it is necessary to adapt to different sizes of the body 14, the operation procedure is as follows: First, unscrew the threaded rod 12 and remove the limiting cylinder 13 to remove the body 14 from the cylinder 8. Then, start the telescopic cylinder 15 to drive the connecting plate 16 to retract the limiting frame 17 upwards until the limiting frame 17 is completely retracted into the base plate 1, releasing the lateral limitation on the frame 4. Then, push the frame 4 so that the T-shaped block 5 on the frame 4 slides and separates along the T-shaped groove 7 of the block 6, and remove the frame 4. Finally, lift the cylinder 8 upwards to separate it from the through hole of the base plate 1. The circular plate 9 will simultaneously detach from the limiting post 10, thus completing the disassembly of the cylinder 8. When replacing it, select a cylinder 8 that matches the size of the body 14 to be positioned (this structure comes with various specifications of cylinder 8). Install it by reversing the above steps to restore the positioning function (the specific installation steps are well known to those skilled in the art and will not be described in detail here).

[0026] To further enhance the wear resistance of the support base 2 and adapt to the needs of long-term placement and frequent movement of the equipment, in this embodiment, a wear-resistant layer is fixedly connected to the bottom of the support base 2. This wear-resistant layer is tightly attached to the bottom of the support base 2, and the stable connection structure ensures that it is not easily detached under long-term stress. The wear-resistant layer effectively reduces frictional loss when the bottom of the support base 2 contacts the ground. Especially when the equipment is moved, its position adjusted, or it is placed on rough ground for a long time, it can reduce the risk of structural deformation of the support base 2 due to wear, thereby extending the service life of the support base 2, ensuring the overall stability of the equipment placement, and indirectly improving the long-term reliability of the positioning mechanism.

[0027] To further enhance the wear resistance of the support base 2 and adapt to the long-term use requirements of the equipment in different ground environments, in this embodiment, the wear-resistant layer at the bottom of the support base 2 is specifically made of PVC material. PVC material has excellent wear resistance and impact resistance, and its molecular structure is stable, effectively resisting frictional wear generated when the support base 2 comes into contact with the ground. Especially when the equipment is moved and adjusted or placed on rough ground for a long time, it can significantly reduce deformation and damage to the bottom of the support base 2 due to wear. At the same time, the PVC material has high fixing strength to the bottom of the support base 2, is not easy to fall off, and can maintain the stability of wear resistance for a long time, thereby extending the service life of the support base 2, ensuring the overall stability of the equipment, and providing a reliable foundation for the accurate operation of the positioning mechanism.

[0028] To facilitate efficient equipment operation and improve the ease of control over key components, in this embodiment, an integrated controller 18 is provided on the front of the base plate 1. The controller 18 establishes a stable electrical connection with the telescopic cylinder 15. The controller 18 can precisely control the telescopic movement of the telescopic cylinder 15 through preset programs or manual operation commands, realizing the rising and retracting and lowering locking functions of the limit frame 17. This design eliminates the cumbersome steps of traditional manual operation, allowing operators to complete the operation without bending over or walking around the equipment. This not only shortens the operation response time but also reduces the movement deviation caused by uneven manual operation force, ensuring more precise cooperation between the limit frame 17 and the frame 4. This provides a reliable control guarantee for the rapid disassembly and switching of the positioning mechanism.

[0029] To further enhance the overall stability of the equipment and ensure structural stability during positioning operations, in this embodiment, several support seats 2 at the bottom of the base plate 1 are symmetrically distributed. The support seats 2 are uniformly and symmetrically arranged with the central axis of the base plate 1 as a reference, which can evenly distribute the overall weight of the equipment to each support point, avoiding localized settlement or tilting due to concentrated force. This symmetrical layout can effectively resist minor external impacts or lateral forces generated during operation, reducing equipment shaking and providing a stable bearing foundation for the positioning mechanism 3, cylinder 8, and other components above. This ensures that the main body 14 maintains its preset posture throughout the positioning process, thereby improving the accuracy and reliability of tire and wheel hub assembly positioning.

[0030] To further improve the connection stability of the positioning mechanism and ensure the matching accuracy between the frame and the block, in this embodiment, the T-block 5 and the T-slot 7 adopt a precise matching design. Their cross-sectional dimensions and shapes are perfectly matched. After the T-block 5 is embedded in the T-slot 7, it can form a tightly fitting sliding connection structure, which not only eliminates the lateral swaying caused by excessive gaps, but also avoids the jamming problem caused by dimensional deviations. This matching relationship can evenly transfer the load when the frame 4 is under force, reduce local stress concentration, and at the same time ensure that the T-block 5 slides smoothly along the preset trajectory in the T-slot 7, providing a stable guide for the disassembly and assembly of the cylinder 8, thereby enhancing the stability of the overall structure in the positioning operation and ensuring the accuracy and reliability of the tire and wheel hub assembly process.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
