DETAILED DESCRIPTION

[0036] The technical solutions of the present application will be described below in conjunction with the embodiments, obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0039] The dynamic material clamping mechanism 3 further comprises a displacement frame plate 34 movably installed at the front end face of the material clamping frame 1, a gas cylinder 35 is arranged between the rear end center of the displacement frame plate 34 and the front end face of the material clamping frame 1, a plurality of groups of vertical grooves two are equidistantly arranged on the upper and lower end faces of the displacement frame plate 34, the end part of each group of transmission cylinders 30 is clamped in the vertical groove, the two groups of clamping rings 32 are respectively sleeved at the front and rear ends of the vertical clamping groove, and the front ends of the upper and lower rows of a plurality of groups of transmission cylinders 30 are respectively sleeved with a concave clamping frame 36.

[0040] A double-shaft motor 37 is arranged at one side of the front end of the displacement frame plate 34 and between the adjacent two groups of concave clamping frames 36, opposite threaded screw rods 371 are fixedly installed at the upper and lower end output shafts of the double-shaft motor 37, the two groups of screw rods 371 are respectively screwed into the corresponding concave clamping frames 36, a transmission gear 38 is jointly meshed between the adjacent two groups of long toothed rollers 33, the rear end shaft of the transmission gear 38 is extended to the front end face of the concave clamping frame 36 and is rotatably connected, and a single-shaft motor 39 is arranged between one group of shafts and the concave clamping frame 36.

[0041] Before the positioning installation of the tire bead, first, a group of hubs is guided out of the material storage frame 2 to the starting end of the dynamic material clamping mechanism 3, the hub is placed at the interval between the upper and lower rows of transmission cylinders 30 and corresponds to the front and rear of the dynamic assembly mechanism 4, then the double-shaft motor 37 is started to drive the two groups of screw rods 371 to rotate in the same direction, the two groups of concave clamping frames 36 are driven to move relative to each other, the upper and lower rows of transmission cylinders 30 are caused to move close to each other by the driving action of the two groups of concave clamping frames 36, the hub is clamped together, the hub is forced to be clamped between the upper and lower rows of transmission cylinders 30, and the pre-holding of the hub is realized.

[0042] Subsequently, the cylinder 35 is started to move the displacement frame plate 34 forward by the push rod, in the process, the displacement frame plate 34 drives the transmission cylinder 30, the snap ring 32 and the clamped wheel hub inside it to move forward synchronously until the front end of the wheel hub abuts against the corresponding vertical roller cylinder 31, assisting the wheel hub to be pushed to the rear end of the upper and lower transmission cylinders 30 in line;

[0043] In order to further limit the wheel hub at the dynamic assembly mechanism 4, the displacement frame plate 34 and the wheel hub are pushed backward by the cylinder 35 and gradually moved to the dynamic assembly mechanism 4, realizing the connection of the wheel hub and the dynamic assembly mechanism 4, at the same time, the double-shaft motor 37 is used to drive the two groups of screw rods 371 to rotate in opposite directions, forcing the two groups of concave clamping frames 36 to move away from each other, and pulling the upper and lower transmission cylinders 30 away from each other to release the limitation on the wheel hub;

[0044] After the wheel hub is sent to the dynamic assembly mechanism 4, the displacement frame plate 34 and the transmission cylinder 30 are reset by the cylinder 35, and the same method is used to tightly hold the bead and send it to the dynamic assembly mechanism 4 to be combined and installed with the wheel hub. Similarly, when the bead is combined and installed with the wheel hub to form a complete tire body, the tire body is clamped and taken out by the above-mentioned clamping method;

[0045] It is worth noting that the single-shaft motor 39 is started to drive a group of transmission gears 38 to rotate by the shaft rod, the transmission gears 38 are engaged with the adjacent long-toothed roller 33, and then drive a plurality of groups of long-toothed rollers 33 and the lower transmission cylinder 30 to rotate synchronously. Since the tire body has been pre-held between the upper and lower transmission cylinders 30, in the rotating process, the bead will gradually move to one side with the rotation of the lower transmission cylinder 30, and will be transported to the designated position by the curved surface rolling of the vertical roller cylinder 31;

[0046] Subsequently, the displacement frame plate 34 is moved forward by the cylinder 35, and the transmission cylinder 30, the snap ring 32 and the clamped tire body move forward synchronously until the front end of the tire body abuts against the vertical roller cylinder 31 again and gradually falls off from the interval between the upper and lower transmission cylinders 30, completing the positioning and unloading of the tire body;

[0047] Through the setting of the dynamic clamping mechanism 3, the automatic pre-holding feeding and positioning and unloading of the bead and the wheel hub are realized, which not only significantly improves the production efficiency, but also effectively avoids the damage of the bead in the conveying process, ensures the production quality of the tire, and further improves the work efficiency.

[0048] Example two: please refer to Figure 4 - Figure 8As shown, the dynamic assembly mechanism 4 comprises a rotating drum 41 arranged on the inner wall of the rear end of the material clamping frame 1, and a motor 42 is arranged between the rotating drum 41 and the inner wall of the rear end of the material clamping frame 1, a cross positioning frame 43 is fixedly installed at the front end of the rotating drum 41, an inner clamping assembly 44 is arranged at the front end of the cross positioning frame 43, and an outer clamping assembly 45 is arranged at the rear end of the cross positioning frame 43;

[0049] The inner clamping assembly 44 comprises two groups of horizontal frames 441 arranged on the front end of the cross positioning frame 43 and distributed upward and downward, a sliding shaft 442 with a convex structure is fixedly sleeved at the center of each end of each group of horizontal frames 441 and the corresponding frame slot of the cross positioning frame 43, the front end shaft rod of the sliding shaft 442 extends to the outside of the horizontal frame 441, an inclined lifting rod 443 is hingedly connected at the center of the opposite surface of each group of horizontal frames 441, and an inner tooth ring cylinder 444 is hingedly connected between the two groups of lifting rods 443, and the rear end cylinder body of the inner tooth ring cylinder 444 is rotatably connected in the front end center frame opening of the cross positioning frame 43;

[0050] The outer clamping assembly 45 comprises two groups of vertical frames 451 arranged on the rear end of the cross positioning frame 43 and distributed left and right, a sliding shaft 452 with a convex structure is penetratingly arranged between the corresponding frame slots of the cross positioning frame 43 and the inside upper and lower ends of each group of vertical frames 451, a pressing rod 453 is movably inserted into the inside of the sliding shaft 452, the pressing rod 453 extends to the outside of the sliding shaft 452 at one end, and a damping spring damping ring 454 is installed between the other end of the pressing rod 453 and the inside of the sliding shaft 452, a lifting rod 455 is hingedly connected at the opposite surface of each group of vertical frames 451, an inner tooth ring cylinder 456 is hingedly connected between the two groups of lifting rods 455, and the front end cylinder body of the inner tooth ring cylinder 456 is rotatably connected in the rear end center frame opening of the cross positioning frame 43;

[0051] A motor 46 is arranged at the center upward of the rear end inner wall of the rotating drum 41, a main rotating gear 47 is fixedly installed at the bottom of the front and rear output shafts of the motor 46 and extends to the inside of the inner tooth ring cylinder 456, the top surface of the main rotating gear 47 is engaged with the top inner wall of the inner tooth ring cylinder 456, an auxiliary rotating gear 48 is engaged at the bottom of the auxiliary rotating gear 48, one end shaft rod of the auxiliary rotating gear 48 extends to the inner wall of the rotating drum 41 and is rotatably connected, the other end shaft rod of the auxiliary rotating gear 48 extends to the inside of the inner tooth ring cylinder 444 and is fixedly installed with an auxiliary rotating gear 49, and the auxiliary rotating gear 49 is engaged with the bottom inner wall of the inner tooth ring cylinder 444;

[0052] The positioning and assembling process of the dynamic assembling mechanism 4 wheel hub includes: starting the motor 2 46 to drive the main gear 1 47 to rotate. Since the main gear 1 47 is engaged with the inner wall of the top of the inner tooth ring cylinder 2 456, the rotation of the main gear 1 47 drives the inner tooth ring cylinder 2 456 to rotate around the center frame opening at the rear end of the cross positioning frame 43. At the same time, the auxiliary gear 1 48 acts as a transfer auxiliary, one end of which is engaged with the main gear 1 47, and the other end is engaged with the inner wall of the bottom of the inner tooth ring cylinder 1 444 through the auxiliary gear 2 49, realizing the reverse rotation of the inner tooth ring cylinder 1 444 around the center frame opening at the front end of the cross positioning frame 43.

[0053] With the rotation of the inner tooth ring cylinder 1 444 and the inner tooth ring cylinder 2 456, they respectively drive the two groups of horizontal frames 441 to move towards each other and the two groups of vertical frames 451 to move away from each other through the hinged lifting rods 1 443 and 2 455. At the same time, the movement of the horizontal frames 441 and the vertical frames 451 will inevitably lead to the synchronous movement of the end shafts 1 442 and 2 452. At this time, the pressure rods 453 at the ends of the shafts 2 452 press against the four corners of the outer ring of the wheel hub, and the ends of the shafts 1 442 press against the inner ring of the wheel hub, forming a stable clamping.

[0054] In addition, according to the operation in Embodiment 1, after the dynamic clamping mechanism 3 is used to clamp the tire bead, it is moved to the dynamic assembling mechanism 4 again. At this time, the inner ring of the tire bead corresponds to the outer ring of the wheel hub, and the tire bead continuously approaches the wheel hub and continuously pushes the pressure rod 453 to press against the inside of the shaft 2 452, so that it is separated from the outer ring surface of the wheel hub. The damping spring shock absorber 454 is compressed, and as the pressure rod 453 is continuously pressed and shrunk, the tire bead can be smoothly fitted on the outer ring of the wheel hub.

[0055] When the tire bead is completely fitted, the dynamic clamping mechanism 3 stops pushing the tire bead, the pressure rod 453 is reset under the elastic force of the damping spring shock absorber 454, and the assembled tire body is pushed away from the dynamic assembling mechanism 4 in the opposite direction.

[0056] At the same time, the motor 2 46 is started again to force the inner tooth ring cylinder 1 444 and the inner tooth ring cylinder 2 456 to reverse, thereby driving the horizontal frames 441 and the vertical frames 451 to move towards each other or away from each other, realizing the release of the wheel hub and even the whole tire body, and ensuring the efficiency and smoothness of the automatic assembly process.

[0057] It is worth mentioning that the outer ring of the rotating drum 41 is fixedly installed with a tooth ring 410 near the rear end, and the tooth ring 410 is engaged with two tooth discs 411 at the center of both sides. The rear center of the two groups of tooth discs 411 is engaged with the inner wall of the rear end of the clamping frame 1 through the fixedly installed shaft, and the front end of the tooth disc 411 is fixedly installed with a limiting long cylinder 412. The far side of the two groups of limiting long cylinders 412 away from the corresponding front and rear ends is fixedly sleeved with a side baffle 413.

[0058] In the positioning and installation process of the tire bead and the wheel hub: the two sets of limiting long barrels 412 can effectively limit the position of the assembled tire bead in the static state, thereby reducing the deviation phenomenon in the assembly process and ensuring the accuracy of the positioning and installation of the tire bead and the wheel hub. When the motor 42 drives the rotating barrel 41 to rotate, the gear ring 410 also rotates. Due to the meshing relationship with the two sets of gear plates 411, the gear plates 411 are also synchronously driven to rotate. The rotation of the gear plates 411 further drives the limiting long barrels 412 to synchronously rotate. The side baffles 413 on the limiting long barrels 412 rotate in turn, intermittently clamping and pressing the tire bead. In this way, the part of the protruding tire bead can be timely clamped and connected with the wheel hub clamping area, further improving the positioning and installation effect of the tire bead.

[0059] The whole dynamic assembly mechanism 4 is arranged to realize stable clamping of the wheel hub and accurate assembly of the tire bead, thereby reducing the misalignment and damage of the wheel hub caused by the deviation of the wheel hub during the assembly process, and effectively improving the efficiency and accuracy of the tire assembly.

[0060] Working principle:

[0061] First, a set of wheel hubs is guided out from the inside of the storage frame 2 to the starting end of the dynamic clamping mechanism 3. The wheel hubs are placed at the interval between the upper and lower transmission barrels 30 and correspond to the front and back of the dynamic assembly mechanism 4. Then, the double-shaft motor 37 is started to drive the two sets of spiral rods 371 to rotate in the same direction, which pulls the two sets of concave clamping frames 36 to move relative to each other. Through the pulling action of the two sets of concave clamping frames 36, the upper and lower transmission barrels 30 are brought close to each other and clamp the wheel hub together, forcing the wheel hub to be firmly clamped between the upper and lower transmission barrels 30, realizing the pre-tightening of the wheel hub and accurately conveying it to the dynamic assembly mechanism 4.

[0062] When the dynamic assembly mechanism 4 is running, the motor 42 and the motor 46 work together to drive the rotating barrel 41 and its internal components to rotate and move. The inner clamping assembly 44 and the outer clamping assembly 45 cooperate to realize stable clamping of the wheel hub through the interaction of the sliding shaft 442, the sliding shaft 452, the lifting rod 443, the lifting rod 455, the inner gear ring cylinder 444, and the inner gear ring cylinder 456, ensuring the stability of the wheel hub during tire bead assembly.

[0063] The above dynamic clamping steps are repeated. The displacement frame plate 34 and the transmission barrel 30 are reset by the cylinder 35, and the tire bead is tightly held and conveyed to the dynamic assembly mechanism 4 in the same way. The tire bead is combined and installed with the wheel hub, and the elastic action of the pressure rod 453 and the damping spring shock absorber 454 is used to realize the smooth setting of the tire bead. Then, the motor 46 is reversed to drive the horizontal frame 441 and the vertical frame 451 to move towards or away from each other, releasing the assembled tire body, and completing the entire assembly process.

[0064] During this period, the ring 410, 411, 412 and side stop tooth disc teeth limit the cooperation, not only effectively limit the position of the assembled tire, ensure the accuracy of the tire and wheel positioning installation, at the same time, the rotation of the long cylinder 412 and the intermittent stop of the side stop 413, can also assist the part of the protruding tire and the wheel hub to be in time with the wheel hub clamping area homing card joint, further improve the positioning installation effect of the tire.

[0065] In summary, it is through the cooperation of dynamic clamping mechanism 3 and dynamic assembly mechanism 4 to realize the stable clamping of wheel hub and the accurate assembly of tire, effectively improve the efficiency and accuracy of tire assembly.
