[0042] As Figures 1 to 11The illustrated vulcanizing machine comprises a base body 10, a middle column 20, a plurality of edge columns 30, a vulcanizing chamber 40, a tire loading mechanism 50 and a tire unloading mechanism 60, a mold adjusting device 70, a mold locking device 80 and a center mechanism 90, the middle column 20 and the edge columns 30 are connected with the base body 10, the middle column 20 and the edge columns 30 are arranged in a V-shaped structure, and the edge columns 30 are located at the ends of the V-shaped structure, and the middle column 20 is located at the corner of the V-shaped structure; the vulcanizing chamber 40 is located in the V-shaped structure, and the vulcanizing chamber 40 comprises an upper main plate 41 and a lower bottom plate 42; among the adjacent middle column 20 and edge column 30, one of the middle column 20 and the edge column 30 is provided with the tire loading mechanism 50, and the other of the middle column 20 and the edge column 30 is provided with the tire unloading mechanism 60; the mold adjusting device 70 is arranged on the upper main plate 41 and is movably arranged relative to the base body 10, and can adjust the relative position between the upper main plate 41 and the lower bottom plate 42; the mold locking device 80 is arranged between the upper main plate 41 and the lower bottom plate 42, and can lock the relative position when the upper main plate 41 and the lower bottom plate 42 are buckled; the center mechanism 90 is connected with the base body 10, at least a part of the center mechanism 90 is located in the vulcanizing chamber 40, and the center mechanism 90 provides steam for the vulcanizing chamber 40.

[0043] The embodiment is arranged in a V-shaped structure, and the tire loading mechanism 50 and the tire unloading mechanism 60 are not arranged on a separate column, but are arranged on the middle column 20 or the edge column 30, thereby canceling the separate support structure of the tire loading mechanism 50 and the tire unloading mechanism 60 of the traditional vulcanizing machine, and integrating the structure and function of the tire loading mechanism 50 and the tire unloading mechanism 60 on the edge column 30 and the middle column 20, so that the middle column 20 and the edge column 30 can not only support the vulcanizing chamber 40, but also support the tire loading mechanism 50 and the tire unloading mechanism 60, thereby simplifying the structure of the vulcanizing machine, saving the occupied space of the vulcanizing machine and reducing the cost, and at the same time, the vulcanizing chamber 40 is arranged in the V-shaped structure, and the mold adjusting device 70, the mold locking device 80 and the center mechanism 90 are arranged around the vulcanizing chamber 40, thereby facilitating the operation of the mold adjusting device 70, the mold locking device 80 and the center mechanism 90 for adjusting the mold, locking the mold, providing steam and the like of the vulcanizing chamber 40, thereby facilitating the smooth vulcanization process of the tire, and being beneficial to improving the work efficiency and energy saving and consumption reduction.

[0044] It should be noted that the up-down direction of the embodiment refers to the arrangement direction of the upper main plate 41 and the lower bottom plate 42, that is, the up-down direction in the V-shaped structure. Figure 1

[0045] As shown in Figure 1 , Figure 2 , Figure 3 ​As shown, in the present embodiment, the vulcanizing chambers 40 are multiple, the tire loading mechanisms 50 and the tire unloading mechanisms 60 are multiple, the tire loading mechanisms 50 are transversely rotatably connected with the edge columns 30, the tire unloading mechanisms 60 are transversely rotatably connected with the middle column 20 and are matched with different vulcanizing chambers 40, and the tire loading mechanisms 50 matched with different vulcanizing chambers 40 are respectively connected with different edge columns 30, and the tire unloading mechanisms 60 matched with different vulcanizing chambers 40 are connected with the same middle column 20, so that through reasonable arrangement of the tire loading mechanisms 50, the tire unloading mechanisms 60 and the vulcanizing chambers 40, multiple tire vulcanization operations can be simultaneously performed, the production efficiency is greatly improved, the structure of the vulcanizing machine is simplified, and the space occupation of the vulcanizing machine is reduced. In the present embodiment, the tire loading mechanisms 50 are rotatably arranged on the edge columns 30, and the tire unloading mechanisms 60 are rotatably arranged on the middle column 20, so that the vulcanizing chambers 40 are arranged between adjacent tire loading mechanisms 50 and tire unloading mechanisms 60, thereby facilitating the tire loading mechanisms 50 and the tire unloading mechanisms 60 to send and take out the tires from the vulcanizing chambers 40. The present embodiment is provided with the middle column 20 and two edge columns 30, one vulcanizing chamber 40 is arranged between each edge column 30 and the middle column 20, so that the present embodiment is provided with two vulcanizing chambers 40, one tire loading mechanism 50 is arranged on each edge column 30, the tire loading mechanisms 50 are arranged on the side of the edge columns 30 away from the middle column 20, two tire unloading mechanisms 60 are arranged on the middle column 20, and the tire unloading mechanisms 60 are arranged on the side of the middle column 20 away from the edge columns 30, so that the two vulcanizing chambers 40 can work simultaneously, thereby improving the working efficiency of the vulcanizing machine. Of course, according to actual conditions, the tire unloading mechanisms 60 can be rotatably arranged on the edge columns 30, and the tire loading mechanisms 50 can be rotatably arranged on the middle column 20, which can also achieve the tire loading and unloading.

[0046] It should be noted that the V-shaped structure of the present embodiment refers to the arrangement of two edge columns 30 symmetrically on both sides of the middle column 20, and the front and rear staggered arrangement between the middle column 20 and the two edge columns 30, which are not distributed on the same straight line, thereby forming a V-shaped structure and forming a setting space for two curing chambers 40. The V-shaped structure has the stability of the triangular structure, and is symmetrical, facilitating the harmonious unity of the actions of the two sides of the middle column 20. The middle column 20 and the edge column 30 of the curing machine of the present embodiment are each provided with an upper main plate lifting oil cylinder, the upper main plate lifting oil cylinder of the middle column 20 is arranged on the side close to the edge column 30, and the upper main plate lifting oil cylinder of the edge column 30 is arranged on the side close to the middle column 20. In this way, the arrangement direction of each upper main plate lifting oil cylinder is parallel to the arrangement direction of the two edge columns 30, so that when the middle column 20 and the edge column 30 synchronously lift the upper main plate 41, it is more fast and smooth, thereby solving the symmetry problem in the lifting process of the upper main plate 41. Of course, according to the actual situation, four edge columns 30 can also be arranged, and the edge columns 30 are arranged around the middle column 20, thereby forming two symmetrical V-shaped structures and forming a setting space for four curing chambers 40 between the edge columns 30 and the middle column 20. The size of the V-shaped structure of the present embodiment can also be changed accordingly according to the different specifications and models of the tire.

[0047] In the embodiment, the tire loading mechanisms 50 connected with different edge columns 30 are synchronously rotated or independently rotated respectively; and / or the tire unloading mechanisms 60 connected with the same middle column 20 are synchronously rotated or independently rotated respectively. Thus, the vulcanizing machine can be flexibly adapted to the tire vulcanizing requirements of different sizes and types, thereby improving the versatility and adaptability of the equipment. Specifically, in the embodiment, the two edge columns 30 are symmetrically arranged relative to the middle column 20, and thus the tire loading mechanisms 50 are symmetrically arranged relative to the tire unloading mechanisms 60. The two tire loading mechanisms 50 can be independently rotated relative to the corresponding edge columns 30, so that the work of the two vulcanizing chambers 40 is independently carried out without interference, thereby improving the flexibility of the vulcanizing machine. The two tire loading mechanisms 50 can also be linked to be synchronously operated, so that the two tire loading mechanisms 50 can synchronously operate to simultaneously load the tires of the corresponding vulcanizing chambers 40, thereby improving the uniformity and neatness of the operation of different vulcanizing chambers 40. The two tire loading mechanisms 50 are symmetrically arranged, and thus the two tire loading mechanisms 50 also form a V-shaped structure. This arrangement makes the stroke distance of the tire loading mechanisms 50 short, realizes the maximum reasonable stroke with the shortest distance, and the stretching and retracting operation is very accurate. The operation of the two tire loading mechanisms 50 is symmetrical and coordinated, which is convenient for precision adjustment. Of course, the difference between the two tire unloading mechanisms 60 and the tire loading mechanisms 50 is that the two tire unloading mechanisms 60 are mounted on the same middle column 20, and the two tire unloading mechanisms 60 are symmetrically arranged on the middle column 20 and also form a V-shaped structure. The specific operation form of the two tire unloading mechanisms 60 is similar to that of the tire loading mechanisms 50, which can be independently operated or linked to operate. Details are not described herein again. According to the actual situation, when more tire loading mechanisms 50 and tire unloading mechanisms 60 are arranged, the linked or independent operation arrangement can also be selected, as long as the operation of different tire loading mechanisms 50 and different tire unloading mechanisms 60 does not interfere with each other.

[0048] In the embodiment, the tire loading mechanism 50 and the tire unloading mechanism 60 are arranged on the corresponding intermediate column 20 and the edge column 30 in a lifting manner, so that the tire can be conveniently loaded into or unloaded from the curing chamber 40, the labor intensity of manual operation is reduced, and the safety and efficiency of operation are improved. Specifically, the intermediate column 20 and the edge column 30 of the embodiment can each adopt a square column, and a linear guide groove is processed on the surface of the column to form a three-column box structure with the seat body 10, and the structure is formed by one-time processing to improve the reliability. The intermediate column 20, the edge column 30 and the seat body 10 can also be welded from plates or profiles. The tire loading mechanism 50 and the tire unloading mechanism 60 are each provided with a lifting linear guide rail, which can be processed by a high-precision machine tool to meet the high-precision requirement. This way can realize the interchangeability between the intermediate column 20 and the edge column 30, and the interchangeability of the positions of the tire loading mechanism 50 and the tire unloading mechanism 60, thereby improving the flexibility of the curing machine and being conducive to saving maintenance costs and adapting to the curing of high-quality tires. In this way, the tire loading mechanism 50 can slide up and down along the linear guide groove of the edge column 30 to load tires at different heights, and the tire unloading mechanism 60 can slide up and down along the linear guide groove of the intermediate column 20 to unload tires at different heights, thereby improving the flexibility and adaptability of the tire loading mechanism 50 and the tire unloading mechanism 60, so that the curing machine of the embodiment can adapt to various working conditions, and at the same time, the intermediate column 20 and the edge column 30 can consider the lifting of the upper main plate 41 of the curing chamber 40 and the lifting of the tire loading mechanism 50 and the tire unloading mechanism 60, thereby improving the integration of the curing machine and simplifying the structure. Of course, there are many ways to lift the tire loading mechanism 50 and the tire unloading mechanism 60, and other lifting methods such as chain lifting can also be selected.

[0049] In the embodiment, the tire loading mechanism 50 and the tire unloading mechanism 60 each have an operating end 531, and when the tire loading mechanism 50 and the tire unloading mechanism 60 rotate into the curing chamber 40, the center of the operating end 531 is vertically aligned with the center of the curing chamber 40, so that the operating end 531 can place the tire in the center of the curing chamber 40 and take the tire out of the center of the curing chamber 40, thereby facilitating uniform heating of the tire during the curing process and improving the curing effect. Specifically, the radius of rotation of the tire loading mechanism 50 of the embodiment is the distance from the edge column 30 to the center of the curing chamber 40, and the radius of rotation of the tire unloading mechanism 60 is the distance from the intermediate column 20 to the center of the curing chamber 40, so that the tire loading mechanism 50 can place the tire in the center of the curing chamber 40, thereby enabling the tire to be uniformly heated. Similarly, the tire unloading mechanism 60 can extend into the center of the curing chamber 40 to take out the tire.

[0050] It should be noted that the vulcanizing chamber 40 of the present embodiment has a vulcanizing cavity in which the tire is vulcanized, and thus the center of the vulcanizing chamber 40, i.e. the center of the vulcanizing cavity, is where the tire is placed, which is beneficial to the uniform vulcanization of the tire at different positions, thereby improving the quality of the tire. Figure 2 The arrows in the figure indicate the movement directions of the tire loading mechanism 50 and the tire unloading mechanism 60.

[0051] As shown in Figure 4 the present embodiment, the mold adjusting device 70 includes an adjusting rod 71, the position of the adjusting rod 71 is fixed relative to the lower bottom plate 42 when the upper main plate 41 is buckled with the lower bottom plate 42, the adjusting rod 71 is threaded in the upper main plate 41 and threadedly cooperates with the upper main plate 41, and the adjusting rod 71 drives the upper main plate 41 to move up and down relative to the lower bottom plate 42 when the adjusting rod 71 rotates. This way of arranging the mold adjusting device 70 on the upper main plate 41 of the vulcanizing chamber 40 makes the opening and closing of the vulcanizing chamber 40 more stable, thereby reducing the wear of the equipment and prolonging the service life of the equipment. Specifically, the adjusting rod 71 of the present embodiment is arranged as a screw rod, one end of the screw rod close to the lower bottom plate 42 is connected with the lower bottom plate 42, and the outer periphery of the screw rod is provided with external threads. The upper main plate 41 is provided with a threaded hole, so that the screw rod can be threaded in the threaded hole of the upper main plate 41 and can drive the movement of the upper main plate 41 when there is relative movement between the threaded hole and the screw rod, thereby achieving mold adjustment. Compared with the conventional arrangement of the mold adjusting device 70 on the lower bottom plate 42, the upper main plate 41 of the present embodiment moves while the lower bottom plate 42 is fixed, so that when the force cylinder for closing the mold at the lower bottom plate 42 acts, the movement distance of the lower bottom plate 42 does not have to be considered, thereby saving the movement stroke of the force cylinder and reducing the complexity of the structure of the vulcanizing machine, while saving costs.

[0052] In the present embodiment, the upper main plate 41 includes a plate body part 411 and a nut 412, the nut 412 is rotatably connected with the plate body part 411 and moves up and down synchronously with the plate body part 411, and the adjusting rod 71 is threaded in the nut 412 and threadedly cooperates with the nut 412. Specifically, the plate body part 411 is arranged as a rectangle and is provided with a mounting hole, the nut 412 is rotatably arranged in the mounting hole, and the adjusting rod 71 is threaded in the nut 412, so that when the nut 412 rotates relative to the adjusting rod 71, the nut 412 can drive the plate body part 411 to move up and down, but will not drive the plate body part 411 to rotate, thereby realizing the movement of the upper main plate 41. In this way, the adjustment of the mold adjusting device 70 is more accurate, thereby improving the quality of tire vulcanization. Alternatively, the adjusting rod 71 can be a T-shaped screw rod, and the nut 412 can be a T-shaped nut.

[0053] In the embodiment, the mold adjusting device 70 further comprises a mold adjusting driving member 72 and a mold adjusting transmission assembly, the mold adjusting driving member 72 is drivingly connected with the nut 412 through the mold adjusting transmission assembly, and the mold adjusting transmission assembly comprises at least one of a gear transmission assembly, a chain transmission assembly and a belt transmission assembly. Specifically, the mold adjusting driving member 72 of the embodiment is provided as a motor, the mold adjusting transmission assembly is provided as a chain transmission assembly, and the chain transmission assembly comprises a chain wheel and chain, so that the chain wheel is connected to the T-shaped nut, the motor drives the chain wheel and chain to drive the T-shaped nut to rotate, and the slot on the adjusting rod 71 is fixed by the fixing block to avoid the relative rotation between the adjusting rod 71 and the upper main plate 41, so that the rotation of the T-shaped nut drives the relative movement between the adjusting rod 71 and the upper main plate 41, thereby driving the upper main plate 41 to move up and down, so as to realize the up and down mold adjusting action. The end of the adjusting rod 71 close to the lower bottom plate 42 is fixed with the lower bottom plate 42, when the extension length of the adjusting rod 71 between the upper main plate 41 and the lower bottom plate 42 increases, it is equivalent to lifting the upper main plate 41 to increase the mold adjusting height, and when the extension length of the adjusting rod 71 between the upper main plate 41 and the lower bottom plate 42 decreases, it is equivalent to sinking the upper main plate 41 to reduce the mold adjusting height. During the mold adjusting process, the lower bottom plate 42 is fixed, and what is changed is the extension length of the adjusting rod 71 relative to the upper main plate 41, which is visible and is conducive to the safety of operation. Considering safety, a protective cover can be arranged outside the adjusting rod 71 and the mold adjusting transmission assembly.

[0060] As Figure 7 , Figure 8As shown, in the present embodiment, the center mechanism 90 comprises: a ring cover 91 and a nozzle 92, the ring cover 91 is arranged at the bottom of the curing chamber 40, the ring cover 91 has a steam channel 911, the steam channel 911 has an air inlet 912 and a spray port 913; the nozzle 92 is arranged at the spray port 913, the steam in the steam channel 911 is sprayed into the curing chamber 40 in a fan shape through the nozzle 92, so as to ensure that the tire is uniformly heated during the curing process, thereby improving the curing effect. Specifically, the curing chamber 40 of the present embodiment also has a capsule for carrying steam inside, the capsule is located above the lower bottom plate 42, the ring cover 91 is located inside the capsule and is connected with the lower bottom plate 42 through a ring seat and the like. The steam channel 911 is distributed along the circumference of the ring cover 91, the spray port 913 is provided with a plurality of spray ports and is distributed on the circumferential side wall of the steam channel 911 and is communicated with the outer circumferential side of the ring cover 91, so as to be able to spray the steam flowing through the steam channel 911 into the capsule. The ring cover 91 increases the nozzle 92 at the position of the conventional spray port 913, the nozzle 92 adopts an atomizing nozzle 92, so as to be able to spray the steam in the steam channel 911 into the capsule in a fan shape, so that the steam is more dispersed and more uniform, and the impact force is very small. In this way, not only can the steam rapidly fill the entire inner cavity of the capsule, but also the steam spraying mode almost reduces the impact force of the steam on the inner wall of the capsule to zero, effectively protecting the capsule, thereby increasing the service life of the capsule. Experiments have proved that the service life of the capsule can be increased by more than 12%, thereby being able to save the manufacturing cost of the tire. At the same time, the steam spraying mode can also ensure the uniformity of the heating of the inner wall of the cured tire, thereby improving the quality grade of the tire. Figure 8 The arrow in the figure indicates the spraying direction of the steam.

[0061] In the embodiment, the inner wall of the air inlet 912 is provided with a plurality of air inlet ribs 9121, which are arranged at intervals along the side wall surface of the air inlet 912, so as to further optimize the distribution of steam and reduce the impact of steam on the capsule. Specifically, the air inlet 912 of the embodiment is located at one end of the steam channel 911 and communicates with the steam channel 911. The steam channel 911 and the air inlet 912 are located on the side of the ring cover 91 close to the lower bottom plate 42, so as to facilitate the connection of the air inlet pipe and the air inlet 912. The steam channel 911 is provided in the form of a fan-shaped groove, and the air inlet 912 located at one end of the steam channel 911 is provided in the form of a mouth-shaped groove. The air inlet pipe and the air inlet 912 are connected in the vertical direction, so that the steam entering the air inlet 912 impacts the side wall in the horizontal direction of the air inlet 912. The air inlet 912 is provided with air inlet ribs 9121 on the side wall arranged in the horizontal direction, so as to form a concave-convex distributed water wave structure on the side wall of the air inlet 912. When the steam impacts the side wall of the air inlet 912, the water wave structure can well buffer the steam, so as to ensure the smoothness of the steam flow, and further reduce the impact of the steam on the capsule. Of course, according to actual requirements, the vertical side wall of the air inlet 912 can also be provided with air inlet ribs 9121, so as to further guide the distribution of steam. When the air inlet 912 is arranged in other directions, the arrangement direction of the air inlet ribs 9121 changes with the direction of the air inlet 912, and the air inlet ribs 9121 are arranged on the side wall of the air inlet 912 impacted by the steam.

[0062] In the embodiment, since the air inlet 912 is arranged in the form of a mouth-shaped structure, the air inlet ribs 9121 are arranged in the form of a ring. Specifically, the air inlet ribs 9121 are also arranged in the form of a mouth-shaped structure, and a plurality of air inlet ribs 9121 form a loop-shaped structure. The size of the mouth-shaped structure of each air inlet rib 9121 is different, and each air inlet rib 9121 is arranged at intervals from the center to the edge of the air inlet 912. In this way, a horizontal wave structure is formed on the side wall of the air inlet 912 impacted by the steam, so as to buffer the steam and ensure the smoothness of the steam flow.

[0063] In the embodiment, the ring cover 91 also has a return air port 914. Similar to the air inlet port 912, the inner wall of the return air port 914 has a plurality of return air ribs 9141, which are arranged along the side wall surface of the air inlet port 912, so as to form a simulated water surface wave structure, so as to buffer the impact of the steam and ensure the stability of the steam flow. The shape of the return air port 914 of the embodiment is similar to that of the air inlet port 912, but in order to facilitate the return flow of the steam, the return air port 914 is not in communication with the steam channel 911, but is adjacent to the steam channel 911. A groove communicating the peripheral surface of the ring cover 91 is arranged on the side of the ring cover 91 close to the lower bottom plate 42. The return air ribs 9141 are adapted to the shape of the return air port 914 and are arranged in an N-shaped form. The opening of the N-shaped form faces the peripheral surface of the ring cover 91. The plurality of return air ribs 9141 are arranged from small to large from the center of the return air port 914 to the edge of the return air port 914, so as to form a concave-convex distributed simulated horizontal wave structure, so as to reduce the impact force on the return air pipe when the steam flows out of the capsule to the return air port 914 and then to the return air pipe, so as to improve the stability and reliability of the entire steam delivery system.

[0064] It should be noted that the vulcanizing machine of the embodiment adopts a B-type center mechanism 90, adopts capsule internal temperature measurement technology, so that the temperature measurement is more accurate, and adopts a multi-channel combined sealing and dust prevention, so that the sealing effect is better, the service life is longer, and the service life can be about 3 times of the average level in the industry.

[0065] As shown in Figure 9 In the embodiment, the tire mounting mechanism 50 and / or the tire unmounting mechanism 60 comprises a clamping device, which comprises a mounting frame 51, a clamping driving member 52, a clamping assembly 53 for clamping the tire, and a first adjusting member 54. The clamping driving member 52 is connected with the mounting frame 51 and has an output portion 521, the movement direction of the output portion 521 being a first direction. The clamping assembly 53 is movably arranged with the mounting frame 51. The clamping driving member 52 is drivingly connected with the first adjusting member 54 and can drive the first adjusting member 54 to move the clamping assembly 53 along the first direction to clamp the tire. The first adjusting member 54 is rotatably connected with the output portion 521 and is threadedly connected with the clamping assembly 53. When the first adjusting member 54 rotates, it drives the clamping assembly 53 to move along the first direction through the threaded structure. In this way, by arranging the first adjusting member 54 to be rotatably connected with the output portion 521 and threadedly connected with the clamping assembly 53, the rotation of the first adjusting member 54 can be converted into the movement of the clamping assembly 53 along the first direction, so as to realize the fine adjustment of the diameter of the clamping region formed by the clamping assembly 53, thereby improving the flexibility and adaptability of the clamping device, while not affecting the movement of the output portion 521 along the radial direction of the tire to clamp or release the tire.

[0066] Specifically, when the first adjusting member 54 rotates, it can drive the clamping assembly 53 to move along the first direction, thereby adjusting the diameter of the clamping area formed by the clamping assembly 53. This allows the clamping device to not only clamp and release the tire, but also, when there is a deviation in the diameter of the tire bead, adjust the diameter of the clamping area through the first adjusting member 54 to match the tire. This avoids the situation in traditional clamping devices where the diameter of the clamping area does not match the diameter of the tire bead, resulting in the clamping assembly 53 not gripping the tire firmly or even being unable to extend into the tire bead to grip it. This greatly improves the flexibility and adaptability of the clamping device, while avoiding manual intervention and improving tire production efficiency. It should be noted that the first direction is... Figure 9 The left-right direction is also one of the multiple radial directions of the tire. When the output part 521 moves in the first direction, it can drive the clamping assembly 53 to move closer to the tire to clamp the tire or away from the tire to release the tire. The clamping area refers to the circular area formed by the clamping assembly 53 when clamping the tire.

[0067] In the embodiment, the clamping assembly 53 comprises an operating end 531 for clamping the tire and a second adjusting member 532, the operating end 531 is movably arranged with the mounting frame 51, so that the second adjusting member 532 can smoothly drive the operating end 531 to move along the first direction. Considering the diameter difference of different specifications of tires, the diameter difference of different specifications of tires is larger than the processing error of the same specification of tires, therefore, the second adjusting member 532 is arranged to quickly adjust the size of the clamping area. The second adjusting member 532 is threadedly connected with the first adjusting member 54, and the second adjusting member 532 is adjustably arranged with the operating end 531 along the first direction, so that the adjustment of the clamping device can not only realize the fine adjustment of the clamping area, but also realize the adjustment of the clamping area in a larger range, so as to clamp different specifications of tires. Specifically, the operating end 531 comprises a driving slide plate, a driven slide plate and a clamping claw, the driving slide plate and the driven slide plate are arranged along the circumference of the tire, and are connected with the clamping claw, so that the clamping claw forms a circular clamping area to clamp the tire. The operating end 531 is adjustably arranged with the second adjusting member 532, when the second adjusting member 532 moves along the first direction, the driving slide plate is driven to move along the first direction, and the driven slide plate is synchronously moved along the radial direction of the tire under the driving of the driving slide plate, so as to adjust the size of the clamping area. Since the second adjusting member 532 is reliably connected with the driving slide plate through the pin assembly, it is ensured that the second adjusting member 532 cannot rotate. The second adjusting member 532 is arranged in the shape of a circular rod with a certain length, or a long plate, and the length direction of the second adjusting member 532 is arranged along the first direction. Since the second adjusting member 532 has a certain length, when adjusting the matching position of the second adjusting member 532 and the operating end 531, the operating end 531 can be driven to move a large displacement, so that the operating end 531 can quickly adjust the size of the clamping area to match different specifications of tires. Alternatively, each clamping claw is connected with the mounting frame 51 through a bolt.

[0068] As Figure 9As shown, in the embodiment, one of the operation end 531 and the second adjusting member 532 has a plurality of adjusting holes arranged along the first direction, and the other of the operation end 531 and the second adjusting member 532 is switchably connected with different adjusting holes to adjust the position of the operation end 531 to clamp different specifications of tires. Specifically, the adjusting holes of the embodiment are arranged on the second adjusting member 532, and the operation end 531 is provided with a connecting hole. When the operation end 531 and the second adjusting member 532 are connected, the adjusting hole and the connecting hole are aligned, and the adjusting hole and the connecting hole are fixed by the pin assembly to lock the position of the second adjusting member 532 and the operation end 531. When adjusting the size of the clamping area, the pin assembly is removed, and the connecting hole is aligned with other adjusting holes to adjust the connection position of the second adjusting member 532 and the operation end 531, thereby adjusting the size of the clamping area. When the clamping device needs to clamp a larger specification of tire, the pin assembly is removed, and the adjusting hole closer to the output portion 521 is selected to cooperate with the connecting hole, so that the operation end 531 moves outward along the radial direction of the tire, thereby forming a larger clamping area to adapt to a larger specification of tire. When a smaller specification of tire needs to be clamped, the adjusting hole farther away from the output portion 521 is selected, and the specific operation process is not described again. Of course, according to the actual situation, the operation end 531 can also not be provided with a connecting hole, but a protrusion is arranged in the direction towards the adjusting hole, so that the protrusion is arranged in the adjusting hole, thereby realizing the fixation of the second adjusting member 532 and the operation end 531, or the adjusting hole can be arranged on the operation end 531, and the connecting hole is arranged on the second adjusting member 532, which can also realize the adjustment of the size of the clamping area by the second adjusting member 532 driving the operation end 531.

[0069] In the embodiment, according to the diameter difference between different specifications of tires that need to be clamped, the distance between the adjusting holes can be adjusted accordingly, or the number of adjusting holes can be adjusted according to the number of different specifications of tires. In this way, when the specification of the clamped tire is changed, the operation end 531 cooperates with the corresponding adjusting hole of the second adjusting member 532, so that the clamping device can quickly adapt to different specifications of tires. Preferably, a scale value is marked on the second adjusting member 532 to correspond to different specifications of tires. When the specification of the clamped tire needs to be adjusted, the operation end 531 is adjusted according to the scale value, and then the second adjusting member 532 and the operation end 531 are fixed by the pin assembly. In operation, the output portion 521 moves along the first direction to drive the driving slide plate to move, thereby opening and closing the entire operation end 531 to realize the clamping and releasing of the tire by the operation end 531.

[0070] As Figure 10 , Figure 11As shown, in the present embodiment, the clamping device further comprises a locking member 55, the clamping assembly 53 has a threaded section, the first adjusting member 54 and the locking member 55 are both in threaded cooperation with the threaded section, and the screw rotation direction of the first adjusting member 54 is opposite to that of the locking member 55, so as to lock the position of the first adjusting member 54 in the first direction, and avoid that the rotation of the first adjusting member 54 affects the size of the clamping area and causes the clamping failure when the clamping drive member 52 is in action. Specifically, the locking member 55 is arranged at the end of the first adjusting member 54 away from the clamping drive member 52, the threaded section is arranged at the end of the second adjusting member 532 away from the operating end 531, and the first adjusting member 54 and the locking member 55 are in cooperation with the threaded section in the first direction in sequence. In this way, after the fine adjustment of the clamping area by the first adjusting member 54 is completed, the locking member 55 is installed to lock the first adjusting member 54; when it is needed to rotate the first adjusting member 54 to fine adjust the clamping area, the locking member 55 needs to be loosened first to unlock the first adjusting member 54, so that the first adjusting member 54 can be rotated, and then the first adjusting member 54 is rotated, so that the clamping assembly 53 moves in the first direction until it is adjusted to the appropriate position capable of clamping the tire, and then the locking member 55 is tightened, so that the clamping drive member 52, the first adjusting member 54 and the clamping assembly 53 become a set of firm and stable structure, and then the clamping device can start the work of clamping the tire. The threaded section in the present embodiment is arranged as external thread, and the threads of the first adjusting member 54 and the locking member 55 are arranged as internal thread. Considering that the opposite screw rotation direction of the two external threads can improve the effectiveness of the locking, the screw rotation direction of the first adjusting member 54 can be opposite to that of the locking member 55. Alternatively, the locking member 55 can adopt a locking nut 412. Of course, the locking of the first adjusting member 54 can also adopt other forms, as long as the locking of the first adjusting member 54 can be realized.

[0071] In the embodiment, the clamping device further comprises a connecting piece 56 and a bearing piece 57. The connecting piece 56 is arranged on the output portion 521, and the first adjusting piece 54 is rotatably sleeved outside the connecting piece 56. The bearing piece 57 is arranged between the connecting piece 56 and the first adjusting piece 54, so that the first adjusting piece 54 is rotatable relative to the output portion 521. Specifically, the first adjusting piece 54, the output portion 521, the connecting piece 56 and the bearing piece 57 are all arranged in a cylindrical shape, and according to the outer diameter from large to small, the first adjusting piece 54, the bearing piece 57, the connecting piece 56 and the output portion 521 are sequentially sleeved. In this way, on the one hand, due to the arrangement of the bearing piece 57, when the first adjusting piece 54 rotates, the clamping assembly 53 can be driven to move along the first direction, and the output portion 521 is not affected. On the other hand, due to the arrangement of the connecting piece 56, when the output portion 521 moves along the first direction, the clamping assembly 53 can be driven to move along the first direction through the transmission of the connecting piece 56, the bearing piece 57 and the first adjusting piece 54, so that the clamping device of the embodiment can realize fine adjustment of the clamping area to match the tire with errors, and can realize larger adjustment of the clamping area to match different specifications of tires. Of course, according to the actual situation, a copper sleeve or other annular piece can be used to replace the bearing piece 57 to realize the rotatable arrangement of the first adjusting piece 54 and the connecting piece 56.

[0072] In the embodiment, the clamping device further comprises a stop ring 58. The stop ring 58 is arranged outside the output portion 521, and the end of the connecting piece 56 abuts against the stop ring 58. The connecting piece 56 has a stop protrusion 581, and a limiting space is formed between the stop ring 58 and the stop protrusion 581. At least a part of the first adjusting piece 54 is located in the limiting space, and the inner wall of the limiting space hinders the movement of the first adjusting piece 54 along the first direction relative to the output portion 521, so as to ensure the reliable connection between the output portion 521 and the connecting piece 56, and the reliable connection between the connecting piece 56 and the first adjusting piece 54.

[0073] The connecting piece 56 of the embodiment is in a cylindrical shape, and a threaded hole is arranged at the end away from the clamping assembly 53. The threaded hole is a blind hole, and the opening of the threaded hole faces the direction of the output portion 521, so that the output portion 521 can be connected with the connecting piece 56 by extending into the threaded hole without going out of the threaded hole. In this way, the two ends of the part where the connecting piece 56 is screwed with the output portion 521 are limited by the stop ring 58 and the bottom of the threaded hole respectively, so as to ensure the effective connection between the output portion 521 and the connecting piece 56, and avoid loosening of the threaded connection. The first adjusting piece 54 of the embodiment has a central hole penetrating through the first adjusting piece 54 along the first direction, and the connecting piece 56 is arranged in the central hole and located at the end of the central hole away from the clamping assembly 53. A stop protrusion 581 is arranged at the outer circumferential side of the end of the connecting piece 56 close to the clamping assembly 53. Compared with the first adjusting piece 54, the length of the connecting piece 56 along the first direction is smaller, so the stop protrusion 581 is located in the central hole and forms a limiting space extending along the first direction with the stop ring 58, so as to limit a part of the first adjusting piece 54 in the limiting space, thereby avoiding the connecting piece 56 from moving along the first direction away from the clamping assembly 53 and causing the connecting piece 56 to come out of the central hole, so as to ensure the reliable connection between the connecting piece 56 and the first adjusting piece 54. In this way, the cooperation of the stop ring 58 and the stop protrusion 581 enables the output portion 521 to be reliably connected with the first adjusting piece 54 along the first direction.

[0074] In the embodiment, the side surface of the first adjusting piece 54 has a first protruding portion 541 and a second protruding portion 542, the first protruding portion 541 and the second protruding portion 542 are located at the same side, the first protruding portion 541 is located in the limiting space, the second protruding portion 542 has a threaded structure for threaded cooperation with the clamping assembly 53, and the first protruding portion 541 and the second protruding portion 542 have an avoiding groove 543 therebetween, and the stop protrusion 581 is located in the avoiding groove 543. Specifically, the central hole of the first adjusting piece 54 includes a first section, a second section and a third section connected in sequence along the first direction, and the diameter of the second section is greater than the diameter of the first section and the diameter of the third section, so as to form the first protruding portion 541 and the second protruding portion 542 at the first section and the third section. In this way, the first protruding portion 541 and the second protruding portion 542 are both located at the inner side wall of the first adjusting piece 54. The first protruding portion 541 is in a circular ring shape, the bearing piece 57 is arranged inside the first protruding portion 541, and the stop protrusion 581 is located between the first protruding portion 541 and the second protruding portion 542. In this way, the stop protrusion 581 and the stop ring 58 are located at the two ends of the first protruding portion 541, so as to ensure the stable connection of the first adjusting piece 54, the connecting piece 56 and the output portion 521 along the first direction. The second protruding portion 542 is also in a circular ring shape, and has an internal thread for threaded connection with the threaded section, so as to convert the rotation of the first adjusting piece 54 into the movement of the clamping assembly 53 along the first direction.

[0075] In this embodiment, the bearing component 57 includes a flanged bearing with a flange located between the retaining ring 58 or the stop protrusion 581 and the first adjusting member 54, thereby ensuring the rotatable arrangement of the first adjusting member 54 and the connecting member 56. Specifically, this embodiment provides two bearing components 57, both of which are rotatably connected to the second adjusting member 532 through a clearance fit, ensuring the flexibility of the second adjusting member 532 when rotating relative to the connecting member 56. In this embodiment, all bearing components 57 are flanged bearings, thereby ensuring the stability of the bearing components 57 and preventing the bearing components 57 from moving along the first direction. Among them, the flange of the bearing component 57 farther away from the clamping assembly 53 is located between the retaining ring 58 and the first adjusting member 54, and the flange of the bearing component 57 closer to the clamping assembly 53 is located within the limiting space and abuts against the stop protrusion 581.

[0076] In this embodiment, the clamping device further includes a clamping detection element 59 and a clamping sensor. The clamping detection element 59 is connected to the output unit 521 or the first adjustment element 54. The clamping sensor is fixedly disposed relative to the mounting bracket 51. When the output unit 521 drives the clamping assembly 53 to move, the clamping sensor senses the position of the clamping detection element 59 to determine the working state of the clamping device. Specifically, as Figure 11 As shown, the clamping device in this embodiment is equipped with a clamping sensor mounting plate. The clamping detection member 59 is fixed to the clamping drive member 52 via the clamping sensor mounting plate. The clamping detection member 59 is fixed to the first adjusting member 54 by screws and can move along the first direction as the output part 521 extends and retracts. Thus, through the rotation of the first adjusting member 54 and its movement along the first direction, the clamping detection member 59 and the clamping sensor are sensed, allowing the clamping sensor to feed back a signal to the control system based on the position of the clamping detection member 59, thereby adjusting the position of the operating end 531 to the correct position and achieving automated control of the opening and closing of the operating end 531. Optionally, the clamping sensor can be a proximity switch, and the clamping detection member 59 can be a proximity switch sensing ring. The proximity switch can sense the position of the proximity switch sensing ring, thereby achieving automated control of the clamping device.

[0077] In this embodiment, the clamping drive 52 can be a cylinder; the mounting bracket 51 can be fixed or a movable robotic arm. In this embodiment, the mounting bracket 51 is a robotic arm, which enables the tire to be transferred when the robotic arm rotates. The robotic arm is provided with a fixed bracket, and the clamping drive 52 is fixed to the robotic arm through the fixed bracket.
