DETAILED DESCRIPTION

[0025] The application will be further described in conjunction with specific embodiments and with reference to the accompanying drawings, in which Figure 1 — Figure 13 : As Figure 1 and Figure 2 shown, a non-highway wheel assembly device includes a tire conveying line 1 and a hub conveying line 2, a clamping device 3 is arranged at the end of the hub conveying line 2, a top of the clamping device 3 is provided with a general truss 4, a tire conveying device 5 is slidably connected to the general truss 4 through a slide rail and a motor, the tire conveying device 5 clamps a tire and transports the tire from an end of the tire conveying line 1 to directly above the clamping device 3, the general truss 4 is provided with a tire mounting device 6 for mounting the tire on the hub, and the tire conveying line 1 and the hub conveying line 2 are both provided with a centering device 7 for keeping the tire or the hub in the middle of the conveying line.

[0026] The tire and the hub are transported to the tire conveying line 1 and the hub conveying line 2 by a material conveying trolley. Continuous feeding is performed by the tire conveying line 1 and the hub conveying line 2, when the hub is conveyed to the clamping device 3 by the hub conveying line 2, the hub is fixed; after the tire is continuously transported on the tire conveying line 1, the tire is transported by the tire conveying device 5 on the general truss 4, and the tire is placed on the hub in the clamping device, and further mounted by the tire mounting device 6, after the tire is assembled, the tire assembly can be transported again by clamping the tire by the tire conveying device 5.

[0027] As shown in Figure 3 , Figure 4 and Figure 5 , the clamping device 3 comprises a clamping base plate 30, and three groups of hub clamping plates 31 of the same structure are circumferentially arranged on the clamping base plate 30. The upper end of the hub clamping plate 31 is radially provided with a clamping jaw fixing plate 32, and the inner end of the clamping jaw fixing plate 32 is fixed with a hub support plate 33 and a hub clamping jaw 34. A tire lifting plate 35 driven by a lifting cylinder is arranged on the clamping jaw fixing plate 32. A tire support plate 36 supported by a support rod is arranged between adjacent hub clamping plates 31. Any tire support plate 36 is fixed with a radially arranged driving oil cylinder, and the piston rod of the driving oil cylinder drives the radially sliding of the opposite clamping jaw fixing plate 32. The middle part of the clamping base plate 30 is rotatably connected with a rotating shaft sleeve 300, and three synchronous pull rods 301 are circumferentially hinged on the rotating shaft sleeve 300. The outer ends of the three synchronous pull rods 301 are respectively hinged with the side walls of the three clamping jaw fixing plates 32. When the driving oil cylinder drives the radial sliding of the clamping jaw fixing plate 32, the synchronous pull rod 301 synchronously drives the synchronous movement of the other two synchronous pull rods 301 through the rotating shaft sleeve 300, and the other two clamping jaw fixing plates 32 synchronously slide radially.

[0028] In the above structure, the clamping device 3 realizes the radial movement of the three clamping jaw fixing plates 32 at the same time through a single driving oil cylinder, realizing the inner supporting clamping of the large size hub.

[0029] Since the off-road tire size is often large, the hub needs to be inclined. The lifting cylinder drives the tire lifting plate 35 to move upward to produce inclination, which facilitates the installation of the tire on the hub. And the three tire lifting plates 35 can realize the lifting effect, which can also be more flexible in the actual assembly process.

[0030] Preferably, the lifting cylinder is radially arranged on the upper end surface of the clamping jaw fixing plate 32, and the output end of the lifting cylinder is fixed with a push-pull plate.

The two ends of the push-pull plate are respectively fixedly connected with the ends of the “X” type connecting rod 37 hingedly connected on the slide rail. When the piston rod of the lifting cylinder pushes the push-pull plate to move radially, the “X” type connecting rod 37 drives the tire lifting plate 35 to move up and down.
