[0045] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0046] like Figure 2 As shown, the fully automatic tire assembly production line system for rail transit in this embodiment includes a support body assembly tool 1, an inner rim and support body assembly tool 2, an outer rim assembly tool 3, a bolt tightening tool 4, a tire nitrogen inflation tool 5, a tire weighing tool 6, a dynamic balancing detection tool 7 and a leakage detection tool 8 and a manipulator 9 which are arranged in sequence.

[0047] Among them, Figure 3As shown, the support body assembly tooling 1 includes a tire skin positioning structure 11, a lifting platform 12, and a first lifting cylinder 13. The first lifting cylinder 13 is arranged below the ground. The lifting platform 12 is connected above the first lifting cylinder 13. The first lifting cylinder 13 can drive the lifting platform 12 to perform lifting movements. The tire skin positioning structure 11 is arranged on the lifting platform 12. The tire skin positioning structure 11 includes relatively arranged slots. The sizes of the slots match and adapt to the tire skin A. The tire skin A is placed in the tire skin positioning structure 11 to complete the positioning.

[0048] When the lifting platform 12 is flush with the working ground, the operator can easily push the tire skin A into the slot (square slot) of the tire skin positioning structure 11, put the three independent support bodies B into the tire skin A, and the first lifting cylinder 13 pushes the lifting platform 12 up to the height of the operator to complete the installation of the three support bodies B and the tire skin A (such as Figure 4 As shown in FIG. 1 , the lifting platform 12 descends, and the tire with the support body B installed enters the production line entrance. The tire is transferred to the inner rim and support body assembly process along the upper roller of the production line.

[0049] like Figure 5 As shown, the inner rim and support body assembly tool 2 includes a limiting structure 24, a working platform 21, an inner rim positioning structure 22, and a second lifting cylinder 23, which are arranged in sequence from top to bottom. The top of the second lifting cylinder 23 is connected to the inner rim positioning structure 22. The inner rim positioning structure 22 is arranged in the same shape as the cavity of the inner rim C and can be pushed into the cavity of the inner rim C for cooperation. The tire skin A of the support body B assembled in the previous process is placed on the working platform 21. The working platform 21 is provided with a cavity to facilitate the inner rim C to be pushed into the tire skin A of the assembled support body B from below. The limiting structure 24 is located above the working platform 21 and can be limited from the top and the side.

[0050] The tire skin A with the support body B assembled is transferred to the working platform 21 of the tooling through the upper roller conveyor line of the production line, and the inner rim C is transferred to the lower part of the working platform 21 through the lower roller conveyor line of the production line. A number of universal balls are installed on the working platform 21, and the tire skin A can be quickly moved to the assembly position on the universal balls. The head of the second lifting cylinder 23 has a contouring structure (inner rim positioning structure 22), which is pushed into the cavity of the inner rim C for matching, so that the inner rim C rises into the center of the support body B and is lifted to the position of the limiting structure 24, completing the assembly of the inner rim C and the support body B (such as Figure 6 shown).

[0051] like Figure 7As shown, the outer rim assembly tool 3 includes an assembly platform 31, an inner rim positioning mechanism 32, a lifting hydraulic cylinder 33, and a limiting mechanism 34; the limiting mechanism 34 is arranged above the assembly platform 31, and the limiting mechanism 34 can limit the outer rim D from the top downward. The top of the lifting hydraulic cylinder 33 is connected to the inner rim positioning mechanism 32, and the inner rim positioning mechanism 32 is arranged in the shape of the cavity of the inner rim C, and can be pushed into the cavity of the inner rim C for matching. A cavity is arranged in the working platform 21, so that the inner rim C (the tire with the inner rim C installed) can be pushed into the outer rim D from the bottom.

[0052] The tire with the inner rim C installed enters the tooling, and the outer rim D is moved to the top of the tire using a crane, and the bolts of the outer rim D are inserted into the mounting holes of the inner rim C. The head of the lifting hydraulic cylinder 33 is equipped with a positioning structure (inner rim positioning mechanism 32), which pushes into the cavity of the inner rim C to lift the tire to the limit mechanism 34, and then applies a set hydraulic pressure to press the outer rim D and the inner rim C tightly, as shown in FIG. Figure 8 shown.

[0053] like Fig. 9 As shown, the bolt tightening tool 4 includes a workbench 41 and a wrench assembly 42. A bracket is arranged above the workbench 41, and the wrench assembly 42 is suspended by the bracket. The wrench assembly 42 includes three tightening wrenches with adjustable torque installed together at a distribution of 120°. The radial position of the wrench can be adjusted to adapt to the tightening of two types of tire bolts (traveling wheel E, guide wheel).

[0054] Because the bolts are tightened on the inner rim C side, the tire from the previous process is turned over to the other side (the reverse side of the tire) by the turning machine and transferred to the tooling workbench 41. The torque value of the wrench assembly 42 can be set and can be quickly switched. The operator only needs to select according to the torque size of the tire product. The torque data after the bolts are tightened will be automatically input into the intelligent end of the production line system (manufacturing execution system MES system). Fig.10 shown.

[0055] like Fig.11 As shown, the tire nitrogen filling tool 5 includes a nitrogen generator and a quick-connect connector, and the nitrogen generator and the tire valve F are connected via the quick-connect connector.

[0056] After the bolts are tightened, the tire is automatically sent to the tire nitrogen filling tooling 5 by the conveyor line. The gas source is provided by the nitrogen generator, which provides high-purity nitrogen (nitrogen purity 99%). The quick-connect connector is connected to the tire valve F, and the inflation valve is opened to inflate the tire. The inflation pressure value is displayed by the digital pressure gauge. When the set pressure is reached, the inflation is stopped, and the pressure data is automatically input into the MES system at the same time.

[0057] like Fig.13As shown, the tire weighing tool 6 includes an electronic scale. The inflated tire is transmitted to the tire weighing tool 6. The tire weighing tool 6 is equipped with an electronic scale on the conveyor line. When the tire is transmitted to the conveyor line, the weight of the tire is measured in real time, and the data is automatically input into the MES system at the same time.

[0058] like Fig.14 As shown, the dynamic balancing test tool 7 includes a dynamic balancing machine 71. After weighing, the tire enters the automatic centering mechanism 72 (only after the tire is centered can the manipulator 9 accurately clamp it). The manipulator 9 grabs the tire and positions it with the main shaft of the dynamic balancing machine 71 through the center hole of the outer rim D. The equipment performs dynamic balancing test. After the test is completed, the system automatically determines the test result, and the dynamic balancing data is automatically input into the MES system. After the test is completed, the manipulator 9 grabs the tire and enters the next process.

[0059] like Fig.15 As shown, the leakage detection tooling 8 includes a detection tank 81. The manipulator 9 grabs the tire after the dynamic balancing test to the leakage detection process, and the outer rim D of the tire faces downward (the valve F faces downward), and is completely immersed in the detection tank 81. The leakage of the tire is observed through a high-definition camera. When the set detection time is reached, the system will alarm to prompt the operator to confirm.

[0060] After the leakage inspection is completed, the robot 9 will turn the outer rim D of the tire upward (the valve F will face upward), drain the water, and then stack the tire on the pallet 82 to complete the entire product off-line.

[0061] The above description is only a preferred embodiment of the present invention and does not constitute a limitation on the protection scope of the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
