Description

Technical Field

[0001] The invention relates to the technical field of tire assembly, in particular to a large automobile tire retaining ring press assembly machine. Background Art

[0002] A tire retainer is a metal ring-shaped component, typically made of high-quality carbon steel or alloy steel, shaped to match the tire's edge profile. The structure and size of the tire retainer vary depending on the tire type and usage scenario. The tire retainer is a crucial safeguard against the tire coming off the wheel hub during operation. Without a tire retainer or improperly installed, the tire may come off the wheel hub due to centrifugal force, inertia, and other factors during driving, especially when encountering bumps, sudden braking, or sharp turns. This can lead to serious safety accidents.

[0003] In existing tire retainer installation methods, manual installation is often the most common method. However, when it comes to large vehicles, their tires have significant characteristics, such as large size and heavy weight. For such large tires, manual installation alone is extremely difficult, and a specialized press machine is usually required.

[0004] Existing tire retainer presses have the following problems when installing large automobile tire retainers: large automobile tires of different specifications and models have different pressure tolerances, but the pressure control systems of some presses are not accurate; the pressure device has inertia, and when it stops after reaching the set value, the sensor response time and the inertia of the device itself will cause the pressure to continue to be applied for a certain distance. At this time, if the pressure exceeds the tire's tolerance limit, it will cause damage to the tire; it is inconvenient to limit and protect the pressure applied to the tire during the press installation process.

[0005] In view of this, the present invention provides a large automobile tire retaining ring press assembly machine. Summary of the Invention

[0006] The purpose of the present invention is to provide a large automobile tire retaining ring press to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned object, the present invention provides a large automobile tire retainer ring press, comprising a chassis, a vertical plate provided on one outer wall of the chassis, a base fixedly connected to the outer wall of the vertical plate near the bottom, a slide groove provided near both ends of the vertical plate, and a support assembly provided between the base and the interior of the vertical plate slide groove;

[0008] The support assembly includes a workbench, the end of the workbench is provided with a snap-fit piece inside the vertical plate slide groove, a long groove is provided near the center of the vertical plate, a press-fit assembly is provided between the chassis and the vertical plate long groove, the press-fit assembly is located above the workbench, and wheels are placed on the top of the workbench;

[0009] The workbench is used to support the wheel, and the pressing assembly is used to press the retaining ring inside the wheel. When the pressing assembly presses downward and touches the tire surface, it pushes the wheel and the workbench downward for compression. When the workbench passes the fastener, the retaining ring will be installed inside the wheel under the drive of the pressing assembly. If the pressing assembly continues to press downward, it will drive the workbench downward for compression to release the pressure.

[0010] As a further improvement of the present technical solution, the support assembly further includes a guide column, which is fixedly connected to the bottom of the workbench and movably connected to the inside of the base.

[0011] As a further improvement of this technical solution, a first elastic member is fixedly connected between the bottom of the workbench and the top of the base, the first elastic member surrounds the outer wall of the guide column, and a snap fastener is provided between one end of the workbench and the inside of the slide groove of the vertical plate.

[0012] As a further improvement of the present technical solution, the fastener includes a slider, and the two sliders are respectively slidably connected to the two sliding grooves of the vertical plate, and the sliders are fixedly connected to the workbench.

[0013] As a further improvement of this technical solution, a groove is provided near the center of the inner wall of the vertical plate slide, a clamping block is movably connected inside the groove of the vertical plate slide, and a second elastic member is fixedly connected between the clamping block and the inside of the vertical plate groove.

[0014] As a further improvement of the present technical solution, the upper and lower outer walls of the clamping block close to one end of the vertical plate slide groove are both beveled, and the clamping block is movably connected between the vertical plate slide groove and the inside of the vertical plate groove.

[0015] As a further improvement of the present technical solution, the pressing assembly includes a cylinder, which is fixedly connected to the inside of the chassis, and a support plate is fixedly connected to the top of the cylinder. The support plate is movably connected between the long grooves of the vertical plates, and a pressure head is fixedly connected to one end of the support plate close to the workbench. The pressure head is located directly above the workbench, and a magnetic suction cup is provided at the bottom of the pressure head.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this large-scale automobile tire retaining ring press machine, when the press-fitting assembly begins to descend and accurately presses on the tire surface, the tire and the workbench will move downward due to the transfer of force. During this process, the workbench moves downward and gradually moves to the position of the fastener. At this time, the workbench will be stuck under the action of the fastener. This brief jam allows the press-fitting assembly to instantly press the retaining ring into the tire, ensuring that the retaining ring can be quickly and accurately installed inside the tire, improving the efficiency and accuracy of installation.

[0018] 2. In this large-scale automobile tire retaining ring press, after the retaining ring is installed, due to the certain reaction time of the sensor and the inertia generated by the movement of the device itself, the interaction of these two factors is very likely to cause pressure to continue to be applied to the tire after the retaining ring is installed. At this time, the support assembly will continue to move downward under the pressure of the pressing assembly. During this downward movement, the contraction force generated by the support assembly can effectively release the pressure of the pressing assembly, avoiding the risk of tire damage due to excessive pressure, thereby reducing the repair costs caused by tire damage.

[0033] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0036] For examples, see Figures 1-8 As shown, the purpose of this embodiment is to provide a large automobile tire retainer ring press, including a chassis 1, a vertical plate 10 is provided on the outer wall of one side of the chassis 1, a base 11 is fixedly connected to the outer wall of the vertical plate 10 near the bottom, a slide groove is provided inside the vertical plate 10 near both ends, and a support assembly 12 is provided between the base 11 and the inside of the slide groove of the vertical plate 10;

[0037] The support assembly 12 includes a workbench 120. The end of the workbench 120 is located inside the slide groove of the vertical plate 10 and is provided with a fastener 123. A long groove is provided near the center of the vertical plate 10. A press-fit assembly 13 is provided between the chassis 1 and the long groove of the vertical plate 10. The press-fit assembly 13 is located above the workbench 120. Wheels are placed on the top of the workbench 120.

[0038] The workbench 120 is used to support the wheel, and the press-fitting assembly 13 is used to press the retaining ring into the wheel. When the press-fitting assembly 13 presses downward and touches the tire surface, it pushes the wheel and the workbench 120 downward to compress. When the workbench 120 passes the fastener 123, the retaining ring is installed inside the wheel under the drive of the press-fitting assembly 13. If the press-fitting assembly 13 continues to press downward, it drives the workbench 120 downward to release the pressure.

[0039] The improvement of this embodiment is that: in the tire retaining ring press machine, the press assembly 13 descends and presses the retaining ring into the tire; when the press assembly 13 contacts the tire surface and continues to press downward, the support assembly 12 begins to elastically deform under the pressure of the press assembly 13;

[0040] When the workbench 120 moves to the position of the fastener 123, a jam occurs. During this critical stage, the press-fitting assembly 13 uses this jam to continuously apply downward pressure, thereby accurately and quickly pressing the retaining ring into the tire, achieving rapid installation of the retaining ring. Once the retaining ring is successfully installed in the tire, if the press-fitting assembly 13 continues to apply downward pressure, the support assembly 12 will continue to move downward under this pressure. During this process, the downward contraction force of the support assembly 12 can effectively release the pressure of the press-fitting assembly 13, thereby preventing damage to the tire caused by the continued pressure of the press-fitting assembly 13.

[0041] Therefore, through the elastic action of the support assembly 12, the pressure is automatically adjusted at different stages of the retaining ring installation, which not only ensures the installation speed, but also prevents excessive pressure from damaging the tire after the installation is completed, improves the installation quality and safety, and reduces the risk of tire damage and maintenance costs.

[0042] First, the specific structure of the support assembly 12 is disclosed. The support assembly 12 also includes a guide post 121, which is fixedly connected to the bottom of the workbench 120 and movably connected to the interior of the base 11. A first elastic member 122 is fixedly connected between the bottom of the workbench 120 and the top of the base 11. The first elastic member 122 surrounds the outer wall of the guide post 121. A snap member 123 is provided between one end of the workbench 120 and the interior of the slide groove of the vertical board 10.

[0043] See Figure 4As shown, the workbench 120 is clamped inside the slide groove of the vertical plate 10 by the fastener 123, and the upward telescopic elastic force of the first elastic member 122 pushes the workbench 120 to move upward to the end of the slide groove of the vertical plate 10. The movement of the workbench 120 drives the guide column 121 to extend and retract inside the base 11, and the stability and balance of the workbench 120 are improved by the guide column 121.

[0044] The fastener 123 includes a slider 1230, and the two sliders 1230 are respectively slidably connected to the two slide grooves of the vertical plate 10, and the sliders 1230 are fixedly connected to the workbench 120; a groove is provided near the center of the inner wall of the slide groove of the vertical plate 10, and a clamping block 1231 is movably connected inside the groove of the slide groove of the vertical plate 10, and a second elastic member 1232 is fixedly connected between the clamping block 1231 and the interior of the groove of the vertical plate 10; the upper and lower outer walls of the clamping block 1231 near one end of the slide groove of the vertical plate 10 are both beveled, and the clamping block 1231 is movably connected between the slide groove of the vertical plate 10 and the interior of the groove of the vertical plate 10;

[0045] See Figure 5 and Figure 7 As shown, when the tire is not placed on the workbench 120, the workbench 120 drives the slider 1230 to move upward under the elastic force of the first elastic member 122, so that the slider 1230 moves to the top of the slide groove of the vertical plate 10. At this time, the second elastic member 1232 drives the clamping block 1231 to extend from the inside of the groove of the vertical plate 10 to the inside of the slide groove, so that the clamping block 1231 is located between the groove of the vertical plate 10 and the inside of the slide groove;

[0046] See Figure 8 As shown, when a tire is placed on top of the workbench 120, the workbench 120 is acted upon downward by the weight of the tire, causing the first elastic member 122 to contract slightly. The elastic coefficient of the first elastic member 122 is relatively large. According to Hooke's law, F=kx (F is the elastic force, and x is the deformation of the elastic member). For example, an elastic member made of high-hardness rubber or a special alloy has a relatively large elastic coefficient. If the tire is placed on such an elastic member, when subjected to the tire's weight G, x=G / k can be obtained from G=kx. The larger the elastic coefficient k, the smaller the deformation x, that is, the contraction pressure exerted on the elastic member by the weight of the tire is relatively small. Therefore, after the tire is placed on the workbench 120, although the workbench 120 drives the slider 1230 to move downward a certain distance, the slider 1230 is still located on top of the clamping block 1231.

[0047] See Figure 9As shown, when the press-fitting assembly 13 drives the retaining ring to move downward, when the press-fitting assembly 13 and the retaining ring touch the tire, the tire and the workbench 120 are compressed downward by the continuous downward pressure of the press-fitting assembly 13, so that the slider 1230 moves downward. When the slider 1230 passes the block 1231, the slider 1230 pushes the block 1231 along the inclined surface of the block 1231, so that the block 1231 contracts into the groove of the vertical plate 10, compressing the second elastic member 1232. At this time, the slider 1230 continues to move downward, and when it passes through the block 1231 and pushes it, the workbench 120 is stuck. Due to the stuck workbench 120, the press-fitting assembly 13 instantly presses the retaining ring into the tire.

[0048] See Figure 9 As shown, after the retaining ring is installed inside the tire, the continuous downward pressure of the pressing assembly 13 drives the workbench 120 and the slider 1230 to move downward continuously. At this time, the slider 1230 is located below the block 1231, and the block 1231 is reset between the slide groove and the inside of the groove of the vertical plate 10 under the elastic force of the second elastic member 1232; at this time, the continuously decreasing pressure of the workbench 120 will drive the first elastic member 122 to continuously contract, and the pressure of the pressing assembly 13 is dispersed by the contraction force of the first elastic member 122, so as to avoid that after the retaining ring is installed in the tire, if the sensor response time and the inertia of the pressing assembly 13 itself cause the pressure to continue to be applied, it is easy to over-squeeze the tire and cause damage to the tire.

[0049] Next, the specific structure of the press-fitting assembly 13 is disclosed. The press-fitting assembly 13 includes a cylinder 133, which is fixedly connected to the inside of the chassis 1. A support plate 132 is fixedly connected to the top of the cylinder 133. The support plate 132 is movably connected between the inner portions of the long grooves of the vertical plate 10. A pressing head 130 is fixedly connected to one end of the support plate 132 close to the workbench 120. The pressing head 130 is located directly above the workbench 120, and a magnetic suction cup 131 is provided at the bottom of the pressing head 131.

[0050] See Figure 2 、 Figure 3 and Figure 6 As shown, the piston rod of the cylinder 133 drives the support plate 132 to move up and down, and the moving force of the support plate 132 drives the pressure head 130 to move up and down, and the pressure head 130 drives the magnetic suction cup 131 to move up and down, pressing the retaining ring inside the tire;

[0051] The magnetic suction cup 131 will absorb retaining rings of different sizes through its own suction force. The working principle of the magnetic suction cup 131 is as known to those skilled in the art. When the magnetic suction cup 131 is close to the tire retaining ring, the retaining ring is within the range of the magnetic field generated by the magnetic suction cup 131. The magnetic field will cause the free electrons inside the retaining ring to move under the action of the magnetic field, thereby generating tiny currents (eddy currents). These eddy currents will interact with the magnetic field, causing the retaining ring to be subjected to electromagnetic suction and firmly adsorbed on the surface of the electromagnetic suction cup 131, thereby achieving adsorption and fixation. Through the action of magnetic force, the retaining ring can be firmly adsorbed on mechanical equipment or workpieces without the use of traditional fasteners such as screws and nuts. This connection method not only simplifies the installation and disassembly process, but also reduces the loss of components and improves work efficiency.

[0052] In summary, the working principle of this solution is as follows:

[0053] In the tire retainer press machine, in the initial state, when the tire is not placed on the workbench 120, the elastic force of the first elastic member 122 pushes the workbench 120; after the workbench 120 is subjected to the force, it drives the slider 1230 to move upward until the slider 1230 reaches the top position of the slide groove of the vertical plate 10; at the same time, the second elastic member 1232 plays a role, driving the clamping block 1231 to expand and contract between the groove of the vertical plate 10 and the slide groove. At this time, the clamping block 1231 is exactly located between the groove of the vertical plate 10 and the inside of the slide groove; during the movement of the workbench 120, the guide column 121 will expand and contract accordingly inside the base 11. This process effectively improves the stability of the workbench 120 and makes its force more balanced;

[0054] When the tire is placed on top of the workbench 120, the workbench 120 begins to move downward due to the weight of the tire, causing the first elastic member 122 to slightly contract. During this process, although the workbench 120 also moves the slider 1230 downward a certain distance, the slider 1230 remains on top of the clamping block 1231.

[0055] Subsequently, the piston rod of the cylinder 133 starts to move the support plate 132 up and down. The movement of the support plate 132 in turn drives the pressure head 130 up and down, and the movement of the pressure head 130 in turn drives the magnetic chuck 131 up and down. When the magnetic chuck 131 drives the retaining ring to move downward and contact the tire, the downward pressure of the retaining ring further compresses the tire and the workbench 120 downward. As the workbench 120 moves downward, the first elastic member 122 continues to contract, and the slider 1230 also moves downward.

[0056] When the slider 1230 passes the clamping block 1231, the slider 1230 pushes the clamping block 1231 along the inclined surface of the clamping block 1231, causing the clamping block 1231 to retract into the groove of the vertical plate 10. During this process, the second elastic member 1232 is compressed. At this time, the slider 1230 continues to move downward. At the moment of passing the clamping block 1231, the workbench 120 is stuck. At the moment when the workbench 120 is stuck, the downward force continuously exerted by the magnetic suction cup 131 can accurately press the retaining ring into the tire.

[0057] When the retaining ring is successfully installed inside the tire, the continuous downward pressure of the magnetic suction cup 131 will drive the workbench 120 and the slider 1230 to continue to move downward; at this time, the slider 1230 moves to the bottom of the block 1231, and the block 1231 is reset under the elastic force of the second elastic member 1232, and is again located between the slide groove and the inside of the groove of the vertical plate 10; in this case, the pressure generated by the continuous downward movement of the workbench 120 will cause the first elastic member 122 to continue to contract, and the contraction force of the first elastic member 122 can effectively disperse the pressure of the press-fitting assembly 13; this can avoid the situation where the pressure is continuously applied due to the delay in the sensor response time and the inertia of the press-fitting assembly 13 after the retaining ring is installed, thereby preventing the tire from being excessively squeezed and damaged;

[0058] When the cylinder 133 drives the support plate 132 to move upward, thereby causing the pressure head 130 and the magnetic suction cup 131 to return upward, the workbench 120 and the tire lose the downward pressure; at this time, the first elastic member 122 rebounds upward, driving the workbench 120 to move upward, and the slider 1230 also moves upward; when the slider 1230 passes the block 1231, the upward impact of the slider 1230 will cause it to push the block 1231 along the inclined surface of the lower end of the block 1231, so that the block 1231 shrinks again into the groove of the vertical plate 10; when the slider 1230 smoothly passes the block 1231 and moves above it, the block 1231 rebounds and returns to the position between the slide groove of the vertical plate 10 and the inside of the groove again; at this point, the slider 1230 drives the workbench 120 to complete the upward return, preparing for the installation of the retaining ring of the next tire.
