[0025] like Figures 1 to 4As shown, an automatic tire mounting device for an automobile assembly line includes a movable base 1, a movable frame 2 for driving the movable frame 2 to move laterally, and a vertical moving mechanism 3 for the movable frame 2. A second limiting wheel 5 is rotatably mounted on the end face of the movable part of the vertical moving mechanism 3, and a first limiting wheel 4 is rotatably mounted on the surface of the movable frame 2. A drive assembly 6 is provided on the top surface of the movable frame 2, and a nut mounting sleeve 7 is fixedly mounted on the end face of each rotating part of the drive assembly 6. The nut mounting sleeve 7, driven by the drive assembly 6, rotates to install nuts and fix the tire to the vehicle body. More specifically, the vertical moving mechanism 3 drives the two sets of second limit wheels 5 to move vertically, thereby adjusting the second limit wheels 5 and the first limit wheels 4 to fix the car tire. The movable frame 2 of the movable base 1 moves laterally, allowing the equipment to adjust the position of the tire laterally so that it is aligned with the car wheel hub, thus realizing the installation of the tire. The drive component 6 drives the nut mounting sleeve 7 to move laterally, so that the nut in the nut mounting sleeve 7 is inserted into the surface of the threaded mounting post of the car wheel hub. The drive component 6 can drive the nut mounting sleeve 7 to rotate, realizing the automatic installation and tightening of the nut, completing the rapid fixing and installation of the tire, and improving the automation level and assembly efficiency of the car assembly line.

[0026] The movable base 1 includes a frame 101. A first motor 102 is fixedly mounted on one side wall of the frame 101, and the output end of the first motor 102 is fixedly connected to a first threaded rod 103 through the side wall of the frame 101. A movable frame 2 is threaded onto the surface of the first threaded rod 103 and slidably mounted on the surface of the frame 101. More specifically, by starting the first motor 102, the first threaded rod 103 is driven to rotate, causing the movable frame 2 to slide along the surface of the frame 101, thereby adjusting the lateral position of the tire to be installed and ensuring that the tire is accurately aligned with the vehicle wheel hub.

[0027] The vertical moving mechanism 3 includes a guide frame 301 fixedly installed on the top and bottom inner sides of the movable frame 2. A second motor 302 is fixedly installed inside the guide frame 301. A second threaded rod 303 is fixedly connected to the output end of the second motor 302. A movable block 304 is threadedly fitted onto the surface of the second threaded rod 303, and the movable block 304 slides on the surface of the guide frame 301. Two sets of first limiting wheels 4 are rotatably mounted on the end faces of the movable block 304. More specifically, the second threaded rod 303 is rotated by starting the second motor 302, causing the movable block 304 to move vertically along the guide frame 301, thereby driving the second limiting wheels 5 to move vertically and adjust their height position to adapt to the needs of different tire specifications.

[0028] The drive assembly 6 includes a side plate 601 fixedly installed on the top surface of the vertical moving mechanism 3, and two sets of electric push rods 602 are fixedly installed on one side wall of the side plate 601. The telescopic part of the electric push rod 602 passes through the side plate 601 and is fixedly installed with a U-shaped frame 603. The end face of the U-shaped frame 603 is fixedly installed with a mounting plate 604. A rotating shaft 605 is rotatably inserted into the mounting plate 604, and a small gear 606 is fixedly sleeved on the surface of the rotating shaft 605. A third motor 607 is fixedly installed on the surface of the U-shaped frame 603, and a large gear 608 is fixedly connected to the output end of the third motor 607 through the U-shaped frame 603. The large gear 608 meshes with the rotating shaft 605, and a nut mounting sleeve 7 is fixedly installed on the end face of the rotating shaft 605. More specifically, before installing the tire and wheel hub, the mounting nut is inserted into the inside of the nut mounting sleeve 7. The electric push rod 602 drives the nut mounting sleeve 7 to move laterally, so that the nut is inserted into the end of the wheel hub threaded stud. The third electric motor 607 drives the large gear 608 to rotate. The large gear 608 meshes with the small gear 606, so that the small gear 606, the rotating shaft 605 and the nut mounting sleeve 7 rotate synchronously. The rotation of the nut mounting sleeve 7 causes the nut thread to be fitted onto the wheel hub stud, thus fixing the tire in place.

[0029] The first limiting wheel 4 is located in the middle of the two sets of second limiting wheels 5, and the surfaces of the first limiting wheel 4 and the second limiting wheel 5 are provided with anti-slip patterns. More specifically, the tire is fixed by the first limiting wheel 4 and the two sets of second limiting wheels 5, and the anti-slip patterns on their surfaces increase the friction with the tire, thereby fixing the tire.

[0030] The movable block 304 has a concave structure and is slidably disposed with respect to the surface of the movable frame 2. More specifically, by sliding the concave movable block 304 with respect to the surface of the movable frame 2, the vertical movement of the movable block 304 is guided and limited by the surface of the movable frame 2.

[0031] In summary: The vertical moving mechanism 3 drives the two sets of second limit wheels 5 to move vertically, allowing adjustment of the second limit wheels 5 and the first limit wheels 4 to fix the car tire. The movable base 1 allows the movable frame 2 to move laterally, enabling the equipment to adjust the tire's position laterally to align it with the car wheel hub, thus achieving tire installation. The drive assembly 6 drives the nut mounting sleeve 7 to move laterally, allowing the nut inside the nut mounting sleeve 7 to be inserted into the surface of the threaded mounting post of the car wheel hub. The drive assembly 6 can also drive the nut mounting sleeve 7 to rotate, achieving automatic installation and tightening of the nut, completing the rapid fixing and installation of the tire, and improving the automation level and assembly efficiency of the car assembly line.
