Description

Technical Field

[0001] This utility model relates to the technical field of tire manufacturing, and specifically to a solid tire wheel clamping device. Background Technology

[0002] Solid tires, due to their superior physical and mechanical properties, such as puncture resistance, high-temperature resistance, wear resistance, and the fact that they never burst, maintain stable and reliable operation under harsh working conditions and heavy loads, significantly improving operational safety and equipment availability. Therefore, solid tires are widely used in low-speed, high-load industrial vehicles (such as forklifts, aerial work platforms, airport towing vehicles, and port handling equipment) and stationary heavy machinery.

[0003] Currently, solid tires are mainly divided into two categories: bonded and non-bonded. Bonded solid tires are made by directly vulcanizing and bonding rubber material to a metal wheel (usually a steel rim or a spoked integral wheel). This structure has outstanding advantages such as high load-bearing capacity, minimal settlement deformation, no damage to the ground, and convenient installation. It is particularly suitable for applications requiring high stability and ground protection, such as aerial work platforms and cleanroom handling equipment, and is therefore favored by many OEMs.

[0004] However, in the actual production process of bonded solid tires, the molding process places high demands on the clamping and positioning of the wheels. Existing technologies generally rely on specialized tooling fixtures to fix the wheels, ensuring the coaxiality and positional accuracy of the wheel and mold during vulcanization. With the continuous expansion of downstream applications, OEMs are exhibiting a highly diversified trend in wheel structure design: wheels used by different manufacturers, and even different models from the same manufacturer, lack uniform standards in terms of spoke structure, number and distribution of mounting holes, center hole size, rim width, and outer diameter. This directly results in a wide variety of wheel types and complex specifications suitable for bonded solid tires.

[0005] Against this backdrop, the traditional "one product, one clamp" dedicated clamping mode has revealed significant drawbacks: on the one hand, in order to meet the production needs of multiple varieties and small batches, enterprises need to stock a large number of dedicated clamps, resulting in high tooling costs; on the other hand, in actual production, frequent clamp changes not only prolong the changeover time and reduce the flexibility and overall efficiency of the production line, but also significantly increase the labor intensity of operators.

[0006] More seriously, due to the lack of standardized positioning benchmarks for some wheels, the existing clamping methods are unable to achieve rapid, accurate, and reliable repeated positioning, which in turn affects the quality of vulcanization molding and may even lead to defects such as product eccentricity and poor adhesion.

[0007] Furthermore, in current production processes, wheel loading typically relies on manual operation. Manual wheel placement is not only inefficient but also makes it difficult to guarantee accurate positioning every time. Workers need to adjust the wheel's position based on experience to ensure precise alignment with the clamp. This manual adjustment method is prone to introducing errors, resulting in wheels not being fully aligned, thus affecting subsequent clamping results. Especially when handling wheels of various sizes, manual placement is even more difficult and has a higher error rate, further reducing production efficiency and increasing the scrap rate.

[0008] Therefore, existing technologies still need further development. Utility Model Content

[0009] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a solid tire wheel clamping device to solve the technical problems of existing solid tire wheel clamping devices relying on manual placement of wheels during the loading process, making it difficult to ensure that the wheels are accurately positioned to the center of the clamp each time, resulting in low positioning accuracy and insufficient automation.

[0010] To achieve the above-mentioned technical objectives, according to one aspect of this utility model: a solid tire wheel clamping device is provided, comprising: a clamping mechanism and a feeding mechanism. The clamping mechanism has a support portion and a clamping portion. The clamping portion is adjustablely disposed on the support portion along the radial direction of the wheel. The support portion and the clamping portion form a clamping space for clamping the wheel. The clamping portion is used to abut against the inner wall of the wheel, so that the clamping size of the clamping space can be adjusted by adjusting the position of the clamping portion relative to the support portion. The feeding mechanism has a feeding portion and an identification portion. The feeding portion is movably disposed for conveying and placing the wheel on the clamping mechanism. The feeding portion is communicatively connected to the identification portion, and the identification portion is used to identify the specification information of the wheel placed on the feeding portion. The feeding portion adjusts the position of the wheel relative to the support portion according to the specification information of the wheel identified by the identification portion, so that when the feeding portion moves to the clamping position, the support portion and the clamping portion are located inside the inner cavity of the wheel.

[0011] Furthermore, the solid tire wheel clamping equipment also includes a controller, which is communicatively connected to the feeding unit and the identification unit respectively. The controller is used to obtain the wheel specification information identified by the identification unit and control the feeding unit to perform actions based on the obtained wheel specification information, so as to adjust the position of the wheel on the feeding unit relative to the support unit.

[0012] Furthermore, the feeding mechanism includes: an identification structure, which is fixedly set at a preset scanning position to form an identification part; a feeding structure, which is movably set to form a feeding part; the feeding structure has a supporting part, which is movably set in the vertical direction and is used to support the wheel, and adjust the height position of the wheel according to the specification information of the wheel identified by the identification structure; wherein, when it is necessary to identify the wheel on the feeding structure, the feeding structure drives the wheel to move to the preset scanning position so that the identification structure can identify the specification information of the wheel.

[0013] Furthermore, the feeding structure includes: a mounting base and multiple rollers, the multiple rollers being rotatably mounted on the bottom of the mounting base to drive the mounting base to move; a lifting part, the lifting part being vertically and vertically mounted on the mounting base; two support frames, the two support frames being spaced apart on the lifting part along the width direction of the mounting base, the two support frames being located on the same side of the lifting part; a receiving space adapted to the outer contour of the wheel is formed between the two support frames, the receiving space being used to place the wheel; the two support frames forming the support part of the feeding mechanism.

[0014] Furthermore, the clamping mechanism includes: a support plate, rotatably disposed; the support plate is provided with multiple guide grooves, the multiple guide grooves are evenly spaced along the circumferential direction of the support plate, and the multiple guide grooves extend along the radial direction of the wheel; multiple clamping blocks, the multiple clamping blocks are disposed one-to-one with the multiple guide grooves, and each clamping block is movably inserted into the guide groove along the extension direction of the guide groove; the multiple clamping blocks form the clamping part of the clamping mechanism; and a drive assembly, the drive assembly is drivenly connected to the multiple clamping blocks respectively, and the drive assembly is used to drive the multiple clamping blocks to move synchronously.

[0015] Furthermore, the driving component includes: a movable member, movably arranged along a preset direction; and multiple links, each link corresponding to a multiple clamping block, with one end of each link hinged to the corresponding clamping block and the other end of each link hinged to the movable member; so that when the movable member moves along the preset direction, each clamping block is driven to move synchronously through each link.

[0016] Furthermore, the movable component includes: a movable shaft, which is movably disposed along a preset direction; a positioning component, which is fixed on the movable shaft and located at the end of the movable shaft near the support plate; and the ends of each connecting rod away from the corresponding clamping block are hinged to the positioning component.

[0017] Furthermore, the driving component also includes: a first driving member, which is drivingly connected to the moving member, and the first driving member is used to drive the moving member to move along a preset direction.

[0018] Furthermore, the positioning component has a positioning body and multiple sliding parts, the multiple sliding parts are spaced apart along the circumferential direction of the positioning body, and each sliding part protrudes from the positioning body. Each sliding part is corresponding to each connecting rod, and the end of each connecting rod away from the corresponding clamping block is hinged to the corresponding sliding part. The clamping mechanism also includes: a support shaft, which extends along a preset direction and is rotatably arranged. The support shaft is connected to a support disk. The support shaft has a moving channel extending along the preset direction and multiple guide holes communicating with the moving channel. The multiple guide holes are spaced apart on the side wall of the support shaft along the circumferential direction, and each guide hole is corresponding to a multiple sliding part. At least a portion of the moving shaft and the positioning body are movably inserted into the moving channel along the preset direction, and each sliding part is inserted into the corresponding guide hole.

[0019] Furthermore, the clamping mechanism also includes: a pressure sensor, which is disposed on one of the clamping blocks and located on the end face of the corresponding clamping block that contacts the wheel, and the pressure sensor is used to detect the clamping force applied by the clamping block to the wheel; or, multiple anti-scratch components, which are disposed one-to-one with the multiple clamping blocks, each anti-scratch component is installed on the end face of the corresponding clamping block that contacts the wheel, and each clamping block contacts the inner wall of the wheel through the corresponding anti-scratch component.

[0020] Beneficial effects: The solid tire wheel clamping device provided by this utility model, using its technical solution, includes a clamping mechanism and a feeding mechanism. The clamping mechanism is used to stably clamp the wheel and has a support part and a clamping part. The support part serves as a basic load-bearing structure, providing support for the wheel. The clamping part is adjustablely mounted on the support part along the radial direction of the wheel and can abut against the inner wall of the wheel. The support part and the clamping part together form a clamping space for clamping the wheel. By adjusting the radial position of the clamping part relative to the support part, the outer diameter of the clamping space, i.e., the clamping size, can be changed, thereby adapting to wheels with different inner diameter specifications and achieving self-centering, damage-free internal support clamping. The feeding mechanism is used to automatically transport and precisely position the wheel at the clamping station. The feeding mechanism has a feeding part and an identification part. The feeding part is movably mounted and used to transport and place the wheel on the clamping mechanism. The loading section is connected to the identification section. The identification section is used to identify the specification information of the wheel placed on the loading section. The loading section adjusts the position of the wheel relative to the support section according to the specification information of the wheel identified by the identification section, so that when the loading section moves to the clamping position, the support section and the clamping section are located in the inner cavity of the wheel, thereby facilitating the smooth unfolding of the clamping section and reliable clamping of the wheel.

[0021] Therefore, by setting up a feeding mechanism and having it work in conjunction with the clamping mechanism, automatic identification and adaptive positioning of solid tire wheels of different specifications are achieved. Specifically, the identification unit in the feeding mechanism can acquire the specification information of the wheel located on the feeding unit in real time, such as inner diameter and height. The feeding unit dynamically adjusts the spatial position of the wheel relative to the support unit based on this information, ensuring that when the wheel moves to the clamping position, the support unit and clamping unit of the clamping mechanism accurately enter the inner cavity of the wheel. Furthermore, the clamping mechanism uses a radially adjustable clamping unit in conjunction with the support unit to form a variable-diameter clamping space. The clamping unit directly abuts against the inner wall of the wheel and unfolds synchronously, achieving self-centering and uniformly stressed internal support clamping; at the same time, the degree to which the clamping unit protrudes from the support unit can be automatically adjusted according to the specific size of the wheel, that is, the diameter of the clamping space can be dynamically adjusted to adapt to various wheel models. This design significantly improves the versatility and flexibility of the equipment, allowing for quick switching of clamping operations for different wheel specifications without manual intervention or replacement of special fixtures, greatly improving production efficiency, and is especially suitable for intelligent production scenarios with multiple varieties and small batches. Furthermore, combined with the precise alignment function of the feeding unit of the feeding mechanism, the entire clamping process has high repeatability and positioning accuracy, effectively avoiding scratches on the wheel surface or edges caused by positional deviations. The overall structure is compact and reliable in operation, ensuring clamping stability while also protecting the workpiece, providing a reliable positioning benchmark for subsequent processes. This solid tire wheel clamping equipment effectively solves the technical problems of existing solid tire wheel clamping equipment that rely heavily on manual wheel placement during the feeding process, making it difficult to ensure that the wheel is accurately positioned to the center of the clamp each time, resulting in low positioning accuracy and insufficient automation.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] Please see Figures 1 to 6 According to an embodiment of the present invention, a solid tire wheel clamping device is provided, comprising: a clamping mechanism 1 and a feeding mechanism 2. The clamping mechanism 1 has a support portion and a clamping portion. The clamping portion is adjustablely disposed on the support portion along the radial direction of the wheel 100. The support portion and the clamping portion form a clamping space for clamping the wheel 100. The clamping portion is used to abut against the inner wall of the wheel 100, so that the clamping size of the clamping space can be adjusted by adjusting the position of the clamping portion relative to the support portion. The feeding mechanism 2 has a feeding portion and an identification portion. The feeding portion is movably disposed for conveying and placing the wheel 100 on the clamping mechanism 1. The feeding portion is communicatively connected to the identification portion, and the identification portion is used to identify the specification information of the wheel 100 placed on the feeding portion. The feeding portion adjusts the position of the wheel 100 relative to the support portion according to the specification information of the wheel 100 identified by the identification portion, so that when the feeding portion moves to the clamping position, the support portion and the clamping portion are located inside the inner cavity of the wheel 100.

[0026] As can be seen, the solid tire wheel clamping device provided by this utility model includes: a clamping mechanism 1 and a feeding mechanism 2. The clamping mechanism 1 is used to stably clamp the wheel 100. The clamping mechanism 1 has a support part and a clamping part. The support part serves as a basic load-bearing structure to provide support for the wheel 100. The clamping part is adjustablely disposed on the support part along the radial direction of the wheel 100 and can abut against the inner wall of the wheel 100. The support part and the clamping part together form a clamping space for clamping the wheel 100. By adjusting the radial position of the clamping part relative to the support part, the outer diameter (i.e., clamping size) of the clamping space can be changed, thereby adapting to wheels 100 with different inner diameter specifications and achieving self-centering, damage-free internal support clamping. The feeding mechanism 2 is used to automatically transport and precisely position the wheel 100 at the clamping station. The feeding mechanism 2 has a feeding part and an identification part. The feeding part is movably disposed for transporting and placing the wheel 100 on the clamping mechanism 1. The loading section is communicatively connected to the identification section. The identification section is used to identify the specification information of the wheel 100 placed on the loading section. The loading section adjusts the position of the wheel 100 relative to the support section according to the specification information of the wheel 100 identified by the identification section, so that when the loading section moves to the clamping position, the support section and the clamping section are located in the inner cavity of the wheel 100, thereby facilitating the smooth unfolding of the clamping section and reliable clamping of the wheel 100.

[0027] Therefore, by setting up the feeding mechanism 2 and having it work in conjunction with the clamping mechanism 1, automatic identification and adaptive positioning of solid tire wheels of different specifications are achieved. Specifically, the identification unit in the feeding mechanism 2 can acquire the specification information (such as inner diameter, height, etc.) of the wheel 100 located on the feeding unit in real time. The feeding unit dynamically adjusts the spatial position of the wheel 100 relative to the support unit based on this information, ensuring that when it moves to the clamping position, the support unit and clamping unit of the clamping mechanism 1 accurately enter the inner cavity of the wheel 100. Furthermore, the clamping mechanism 1 uses a radially adjustable clamping unit in conjunction with the support unit to form a variable-diameter clamping space. The clamping unit directly abuts against the inner wall of the wheel 100 and unfolds synchronously, achieving self-centering and uniformly stressed internal support clamping; at the same time, the degree to which the clamping unit protrudes from the support unit can be automatically adjusted according to the specific size of the wheel 100, that is, the diameter of the clamping space is dynamically adjusted, thereby adapting to various models of wheels 100. This design significantly enhances the versatility and flexibility of the equipment, allowing for rapid switching between clamping operations for different wheel specifications without manual intervention or replacement of specialized fixtures. This greatly improves production efficiency, making it particularly suitable for intelligent production scenarios involving multiple varieties and small batches. Furthermore, combined with the precise alignment function of the feeding mechanism 2, the entire clamping process boasts high repeatability, effectively preventing scratches on the wheel surface or edges caused by positional deviations. The overall structure is compact and reliable, ensuring both clamping stability and workpiece protection, providing a reliable positioning benchmark for subsequent processes. This solid tire wheel clamping equipment effectively solves the technical problems of existing solid tire wheel clamping equipment, which relies heavily on manual wheel placement during the feeding process, making it difficult to ensure that the wheel is accurately positioned in the center of the fixture each time, resulting in low positioning accuracy and insufficient automation.

[0028] The aforementioned "wheel specifications" can be understood as key parameters characterizing the geometric dimensions and / or structural features of wheel 100, especially the inner diameter dimensions directly related to clamping compatibility. Specifically, this may include, but is not limited to, the following: Wheel inner diameter (i.e., rim inner cavity diameter): As the core parameter that determines the radial adjustment of the clamping part, it directly affects the setting of the clamping space; Wheel outer diameter: Used to determine the support height or center position of the wheel in order to adjust the vertical positioning of the feeding mechanism or support and ensure that the wheel is placed stably; Wheel width (axial dimension): used to help determine whether the wheel is properly positioned in the axial direction, or to control the axial travel of the clamping mechanism; Wheel type or model code: can be linked to a preset clamping parameter database to automatically call the corresponding clamping strategy and positioning parameters.

[0029] Specifically, the solid tire wheel clamping equipment also includes a controller, which is communicatively connected to the feeding unit and the identification unit. The controller is used to obtain the specification information of the wheel 100 identified by the identification unit, and to control the feeding unit to perform actions based on the obtained specification information of the wheel 100, so as to adjust the position of the wheel 100 on the feeding unit relative to the support unit.

[0030] By adopting the above-described structure and establishing communication connections between the controller and the loading and identification units, intelligent control of the clamping process is achieved. The controller can acquire the specification information (such as inner diameter and height) of the wheel 100 identified by the identification unit in real time, and automatically calculate the required positioning position of the wheel 100 based on a preset algorithm or parameter database. This allows for precise control of the loading unit to perform corresponding moving or lifting actions, dynamically adjusting the spatial posture of the wheel 100 relative to the support unit. This design eliminates manual judgment and adjustment, significantly improving the automation level and response speed of the clamping preparation stage. Simultaneously, since the positioning action is driven in a closed loop by the controller based on the actual identification results, clamping misalignment caused by human error or specification misjudgment is avoided. This not only improves repeatability but also effectively prevents interference or uneven clamping between the clamping mechanism and the wheel, thus ensuring the integrity of the wheel surface and the reliability of the clamping. The overall system responds quickly and controls precisely, providing strong support for the flexible and unmanned production of multi-specification solid tire wheels.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the feeding mechanism 2 includes: an identification structure 3, which is fixedly set at a preset scanning position to form an identification part; and a feeding structure 4, which is movably set to form a feeding part. The feeding structure 4 has a supporting part, which is movably set in the vertical direction. The supporting part is used to support the wheel 100 and adjust the height position of the wheel 100 according to the specification information of the wheel 100 identified by the identification structure 3. When it is necessary to identify the wheel 100 on the feeding structure 4, the feeding structure 4 drives the wheel 100 to move to the preset scanning position so that the identification structure 3 can identify the specification information of the wheel 100.

[0032] By adopting the above structural setup, the identification structure 3 is fixedly set at the preset scanning position, while the loading structure 4 is designed to be movable, and the supporting part of the loading structure 4 is designed to move vertically, thus forming a collaborative working mechanism of "moving workpiece, fixed identification". This layout avoids the complex wiring, signal interference, and vulnerability risks associated with installing precision identification components on the loading structure 4, significantly improving the stability and service life of the identification system. Simultaneously, during operation, the loading structure 4 first transports the wheel 100 to the fixed preset scanning position, where the precisely positioned and environmentally stable identification structure 3 efficiently and accurately collects the wheel 100's specification information (such as inner diameter and height). After identification, the supporting part moves vertically according to the wheel 100's specification information, thereby adjusting the wheel 100's vertical height to ensure precise alignment with the clamping mechanism 1 when the loading structure 4 moves the wheel 100 to the clamping position. This design not only ensures identification accuracy but also simplifies the overall structure and reduces manufacturing and maintenance costs.

[0033] Furthermore, the identification structure 3 includes a support base 31 and an identification element 32. The support base 31 is fixedly installed, and the identification element 32 is installed on the support base 31. The identification element 32 is used to identify the specification information of the wheel 100 placed on the feeding structure 4.

[0034] Optionally, the identification element 32 is an optical scanning detection element.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, the feeding structure 4 includes: a mounting base 41 and multiple rollers 42, the multiple rollers 42 being rotatably disposed at the bottom of the mounting base 41 to drive the mounting base 41 to move; a lifting part 43, the lifting part 43 being vertically and vertically disposed on the mounting base 41; two support frames 44, the two support frames 44 being spaced apart on the lifting part 43 along the width direction of the mounting base 41, the two support frames 44 being located on the same side of the lifting part 43; a receiving space adapted to the outer contour of the wheel 100 is formed between the two support frames 44, the receiving space being used to place the wheel 100; the two support frames 44 forming the support part of the feeding mechanism 2.

[0036] With the above-described structure, multiple rollers 42 are rotatably mounted on the bottom of the mounting base 41, enabling the entire feeding structure 4 to move smoothly and with low resistance along the track or the ground, facilitating the efficient transport of the wheel 100 to the preset scanning and clamping positions. The lifting unit 43 is integrated into the mounting base 41, and two support frames 44 are spaced apart along the width of the mounting base 41 on the same side of the lifting unit 43, together forming the support portion of the feeding mechanism 2. The lifting unit 43 drives the two support frames 44 to rise and fall synchronously in the vertical direction, thereby adjusting the height position of the wheel 100 placed on the two support frames 44. Simultaneously, the accommodating space formed between the two support frames 44 is adapted to the outer contour of the wheel 100, ensuring not only that the wheel 100 remains stable and does not shift during transportation and positioning, but also automatically achieving radial alignment when the wheel 100 is placed on the support frame 44. Therefore, when the feeding structure 4 moves to the clamping position, only the height of the wheel 100 needs to be adjusted by the lifting part 43, without the need for additional position correction in the X-axis or Y-axis direction, which significantly simplifies the positioning control logic and improves the system response speed and operational reliability.

[0037] Furthermore, the two support frames 44 are arranged symmetrically with their sides (i.e., inner sides) tilted to form a V-shaped or arc-shaped support surface, which is adapted to the outer contour of the wheel rim of the wheel 100. When the wheel 100 is placed on the support frame 44, it automatically slides to the symmetrical center position of the two support surfaces under the action of gravity, thereby achieving radial self-centering.

[0038] Among them, such as Figure 2 As shown, arrow A points in the direction of the width of mounting base 41.

[0039] Specifically, such as Figures 3 to 5 As shown, the clamping mechanism 1 includes: a support disk 5, which is rotatably disposed; the support disk 5 forms a support portion of the clamping mechanism 1; the support disk 5 is provided with a plurality of guide grooves 50, which are evenly spaced along the circumferential direction of the support disk 5, and all the guide grooves 50 extend along the radial direction of the wheel 100 (i.e., the radial direction of the support disk 5); a plurality of clamping blocks 6, which are disposed one-to-one with the plurality of guide grooves 50, and each clamping block 6 is movably inserted into the guide groove 50 along the extension direction of the guide groove 50; the plurality of clamping blocks 6 form a clamping portion of the clamping mechanism 1; and a drive assembly 7, which is drivenly connected to the plurality of clamping blocks 6, and the drive assembly 7 is used to drive the plurality of clamping blocks 6 to move synchronously.

[0040] By adopting the above-mentioned structural configuration, guide grooves 50 are evenly distributed circumferentially and extend radially on the rotatable support plate 5, and multiple clamping blocks 6 are slidably assembled into the guide grooves 50 one by one. The drive assembly 7 drives them to move synchronously. This not only ensures that each clamping block 6 moves strictly along the radial direction of the wheel 100, achieving high-precision self-centering clamping and effectively improving clamping coaxiality and repeatability, but also avoids uneven loading or workpiece damage caused by uneven force. At the same time, the rotatable design of the support plate 5 allows the clamped wheel 100 to rotate with it, facilitating continuous operation in subsequent processes. The overall structure has good rigidity, strong synchronization, and stable operation, taking into account clamping reliability, workpiece protection, and process adaptability.

[0041] Furthermore, the support plate 5 is provided with a plurality of positioning blocks 11, which are arranged at intervals along the circumference of the support plate 5 and located on the side of the support plate 5 closer to the wheel 100; while each guide groove 50 is provided on the side of the support plate 5 away from the wheel 100. The positioning blocks 11 are used to contact the spokes of the wheel 100 to perform circumferential positioning of the wheel 100, thereby ensuring the accuracy and repeatability of the clamping position.

[0042] Specifically, such as Figure 3 and Figure 5 As shown, the drive assembly 7 includes: a movable member 71, which is movably arranged in a preset direction; and multiple connecting rods 72, which are arranged one-to-one with multiple clamping blocks 6. One end of each connecting rod 72 is hinged to the corresponding clamping block 6, and the other end of each connecting rod 72 is hinged to the movable member 71. This is so that when the movable member 71 moves in the preset direction, each clamping block 6 is driven to move synchronously through each connecting rod 72.

[0043] With the above-described structure, each connecting rod 72 is hinged between the moving part 71 and the corresponding clamping block 6. When the moving part 71 moves linearly in a preset direction, the synchronous pushing and pulling action of the connecting rods 72 forces all clamping blocks 6 to radially expand or retract synchronously along the guide groove 50 on the support plate 5. This structure achieves high consistency in multi-point clamping through simple mechanical linkage, ensuring synchronous movement and uniform force distribution of each clamping block 6 without the need for an independent drive unit, effectively avoiding clamping eccentricity or local overload. Simultaneously, the hinged connection allows for a certain angle compensation, adapting to assembly tolerances and improving the smoothness and durability of the mechanism's operation. The overall structure is compact, responsive, and highly reliable, significantly enhancing the stability and adaptability of the clamping process.

[0044] Furthermore, such as Figure 5As shown, the movable component 71 includes: a movable shaft 711, which is movably arranged along a preset direction; a positioning component 712, which is fixed on the movable shaft 711 and is located at one end of the movable shaft 711 near the support plate 5; and the ends of each connecting rod 72 away from the corresponding clamping block 6 are hinged to the positioning component 712.

[0045] With the above-described structure, the positioning element 712 is fixed to the end of the moving shaft 711 near the support plate 5, serving as a unified hinge fulcrum for multiple connecting rods 72. This design concentrates the connections of the dispersed connecting rods 72 onto a single rigid positioning element, simplifying the assembly structure and ensuring that each connecting rod 72 experiences uniform force and synchronized movement under the drive of the moving shaft 711. This effectively avoids transmission errors or mechanism jamming caused by dispersed connection points. Simultaneously, the positioning element 712's proximity to the support plate 5 shortens the force transmission path, improves transmission rigidity and response accuracy, and makes the radial movement of the clamping block 6 more stable and reliable, further ensuring the coaxiality and repeatability of the wheel 100 clamping.

[0046] Furthermore, the drive assembly 7 also includes a first drive member, which is drively connected to the moving member 71, and is used to drive the moving member 71 to move along a preset direction.

[0047] Optionally, the first driving component is a cylinder.

[0048] Furthermore, the controller is also communicatively connected to the first drive component. When the loading structure 4 moves to the clamping position, the controller automatically calculates the required clamping dimensions based on the specification information of the wheel 100 (such as inner diameter and height) obtained by the recognition unit (i.e., recognition structure 3), and controls the stroke or output force of the first drive component accordingly, driving the moving component 71 to move along a preset direction. This, in turn, drives each clamping block 6 to simultaneously unfold to the target position via the connecting rod 72, ensuring that each clamping block 6 fits tightly against the inner wall of the wheel 100. This closed-loop control mechanism achieves integrated intelligent clamping of "recognition-decision-execution-feedback": it not only ensures moderate clamping force and accurate positioning, but also adapts to different wheel specifications, avoiding workpiece damage due to excessive clamping or slippage due to insufficient clamping. At the same time, since the clamping action is triggered on demand by the controller, the system response is faster and the cycle time is more compact, significantly improving the automation level, operational safety, and production flexibility of the equipment.

[0049] Specifically, such as Figures 3 to 5As shown, the positioning member 712 has a positioning body and a plurality of sliding parts 7121. The plurality of sliding parts 7121 are spaced apart along the circumferential direction of the positioning body, and each sliding part 7121 protrudes from the positioning body. Each sliding part 7121 is correspondingly arranged with each connecting rod 72. The end of each connecting rod 72 away from the corresponding clamping block 6 is hinged to the corresponding sliding part 7121. The clamping mechanism 1 also includes a support shaft 8, which extends along a preset direction and is rotatably arranged. The support shaft 8 is connected to the support disk 5 to allow passage. The support shaft 8 drives the support disk 5 to rotate; the support shaft 8 is provided with a moving channel 81 extending in a preset direction, and a plurality of guide holes 82 connected to the moving channel 81. The plurality of guide holes 82 are spaced apart on the side wall of the support shaft 8 in the circumferential direction, and the plurality of guide holes 82 are correspondingly provided with a plurality of sliding parts 7121; wherein, at least a part of the moving shaft 711 and the positioning body are movably inserted in the moving channel 81 in the preset direction, and each sliding part 7121 is inserted in the corresponding guide hole 82.

[0050] By adopting the above-described structure, multiple sliding parts 7121, which are circumferentially spaced and protrude from the positioning body, are provided on the positioning member 712. Each sliding part 7121 passes through a corresponding guide hole 82 on the side wall of the support shaft 8. At the same time, the moving shaft 711 and the positioning body are accommodated in the moving channel 81 inside the support shaft 8. This not only exposes part of the structure of the sliding part 7121 outside the support shaft 8, making it easy to hinge with the corresponding connecting rod 72, but also achieves high-precision composite constraint on the moving member 71: on the one hand, the guide hole 82 restricts the radial displacement and circumferential rotation of the sliding part 7121, ensuring that the positioning member 712 maintains a stable posture during axial movement, effectively preventing the connecting rod 72 from jamming or uneven force due to swaying; on the other hand, this structure completely decouples the linear motion of the moving member 71 from the rotational motion of the support shaft 8 (and the connected support disk 5)—the support shaft 8 can rotate freely to drive the wheel 100 to rotate, while the moving shaft 711 only slides axially to drive the clamping action, without interfering with each other. This design not only significantly improves the accuracy and reliability of the synchronous unfolding of the clamping block 6, but also avoids the wear, vibration or positioning drift problems caused by motion coupling in traditional structures. The overall mechanism is rigid, runs smoothly and has a long service life, providing a solid guarantee for solid tire wheels to achieve high-precision rotation operations in the clamped state.

[0051] Furthermore, the clamping mechanism 1 also includes a base 10, which is fixedly installed, and the support shaft 8 is rotatably inserted inside the base 10.

[0052] Furthermore, the base 10 includes: an equipment connection part 101 and a bushing 102. The equipment connection part 101 is used for fixed connection with the molding equipment. The bushing 102 is installed on the equipment connection part 101 and is located at the bottom of the equipment connection part 101. The support shaft 8 is rotatably inserted into the bushing 102.

[0053] Furthermore, a bearing is provided inside the bushing 102, through which the support shaft 8 is rotatably supported in the bushing 102.

[0054] Furthermore, the clamping mechanism 1 also includes a second driving member, which is drivenly connected to the support shaft 8 to drive the support shaft 8 to rotate.

[0055] Optionally, the second driving component is a motor.

[0056] Specifically, such as Figure 6 As shown, the clamping mechanism 1 also includes a pressure sensor 9, which is disposed on one of the clamping blocks 6 among a plurality of clamping blocks 6, and the pressure sensor 9 is located on the end face of the corresponding clamping block 6 that contacts the wheel 100. The pressure sensor 9 is used to detect the clamping force applied by the clamping block 6 to the wheel 100.

[0057] With the above-described structure, a pressure sensor 9 is integrated on the end face of one of the clamping blocks 6 that contacts the wheel 100, for real-time detection of the clamping force applied by the clamping block 6 to the wheel 100. Since multiple clamping blocks 6 move synchronously through the drive assembly 7 and are structurally symmetrical, the clamping force measured at a single point can effectively characterize the overall clamping state. This design achieves closed-loop force feedback control of the clamping process: on the one hand, it prevents excessive clamping force from causing surface damage or deformation of the wheel 100; on the other hand, it avoids insufficient clamping force causing slippage or displacement of the wheel 100 during subsequent rotation or processing. Simultaneously, only one sensor is needed to meet monitoring requirements, balancing system reliability and cost-effectiveness, and providing precise and safe force control for automated clamping.

[0058] Optionally, there is at least one pressure sensor 9. The number of pressure sensors 9 can be adjusted according to the actual situation. One pressure sensor 9 is provided on one clamping block 6.

[0059] Optionally, when a pressure sensor 9 is provided on the clamping block 6, the pressure sensor 9 is communicatively connected to the controller. The controller acquires the clamping force signal detected by the pressure sensor 9 in real time, and dynamically adjusts the output pressure of the first driving component (such as a cylinder) accordingly, so that the clamping force is always maintained within a safe range that is compatible with the material and specifications of the wheel 100—ensuring sufficient clamping reliability while effectively preventing damage to the rim surface or structural deformation due to overload.

[0060] In addition, this pressure feedback mechanism can also serve as a safety protection function: when the system detects an abnormal decrease in clamping force (e.g., wheel 100 coming loose or not being properly clamped), the controller can immediately trigger an emergency stop command to stop the equipment from running, thus avoiding equipment damage or safety accidents caused by workpiece falling off, and significantly improving the overall intelligence level and operational safety of the machine.

[0061] In addition to the pressure sensor 9 on the clamping block 6, the clamping mechanism 1 also includes multiple anti-scratch components, each corresponding to one of the clamping blocks 6. Each anti-scratch component is installed on the end face of the corresponding clamping block 6 that contacts the wheel 100, and each clamping block 6 contacts the inner wall of the wheel 100 through its corresponding anti-scratch component. This structural arrangement, by using anti-scratch components, allows the clamping block 6 to indirectly contact the inner wall of the wheel 100 via these components. This design effectively avoids the metal clamping block directly pressing against the wheel surface, significantly reducing the risk of scratches, indentations, or coating damage, and is particularly suitable for solid tire wheels where high inner wall surface quality is required. Furthermore, the anti-scratch components are typically made of elastic, wear-resistant materials (such as polyurethane or nylon), which not only have good cushioning and friction performance but also improve clamping stability. In addition, as consumable parts, the anti-scratch components can be replaced individually, resulting in low maintenance costs and extending the service life of the clamping blocks and the entire machine, thus balancing workpiece protection, clamping reliability, and equipment economy.

[0062] In addition, the end faces of each clamping block 6 that contact the inner wall of the wheel 100 can be structurally optimized, for example, by adjusting their contour shape or surface texture (such as setting embossed textures, knurling, anti-slip grooves or high-friction coatings, etc.) to increase the friction between them and the wheel 100, thereby improving clamping stability and preventing the wheel from slipping or shifting during rotation or processing.

[0063] Optionally, the working process of the solid tire wheel clamping equipment is as follows: First, the feeding structure 4 moves to the wheel placement station, and the wheel 100 is placed on the support frame 44 of the feeding structure 4 by mechanical equipment or manual labor. Then, the feeding structure 4 drives the wheel 100 to the preset scanning position, and the recognition structure 3 scans and recognizes the wheel 100 to obtain the specification information of the wheel 100 (such as inner diameter, outer diameter, width or model).

[0064] After identification is completed, the identification structure 3 transmits the acquired wheel 100 specification information to the controller. The controller controls the lifting part 43 of the feeding structure 4 to lift and lower according to the information, thereby driving the support frame 44 and the wheel 100 to move in the vertical direction, adjusting the height position of the wheel 100 so that the axis of the wheel 100 is coaxially aligned with the axis of the support plate 5.

[0065] After the height adjustment is completed, the loading structure 4 transports the wheel 100 to the clamping position. When the wheel 100 reaches this position, the support plate 5 and multiple clamping blocks 6 are already located in the inner cavity of the wheel 100.

[0066] Once the wheel 100 is accurately in place, the controller activates the first drive component (such as a cylinder), which drives the moving component 71 to move along a preset direction. This, in turn, drives multiple clamping blocks 6 to expand radially outward through each connecting rod 72 until they are tightly fitted against the inner wall of the wheel 100, thus completing reliable clamping.

[0067] After clamping is completed, the feeding structure 4 automatically retracts from the clamping position and returns to the wheel release station or the designated waiting position to prepare for the next round of operation.

[0068] It should be noted that after the controller acquires the wheel specification information collected by the identification structure 3, it is not only used for clamping and positioning, but also can be used synchronously for subsequent related processes (such as setting processing parameters, selecting process paths, or quality traceability), thereby realizing intelligent collaborative control of the entire process.
