Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing equipment, in particular to a tire hub pre-assembly material preparation machine for a tire automatic assembly line. Background Art

[0002] In the prior art, when assembling the tire hub, the hub is conveyed by the lower conveying device, and the tire is conveyed by the upper conveying device. When the hub is conveyed to the preset position, the tire is conveyed obliquely downward from the upper conveying device to the hub until the tire is obliquely sleeved on the hub, and then both are further conveyed to the manipulator, which completes the assembly of the tire hub. In the prior art, when the tire descends, it mainly slides downward by its own gravity. When the height difference between the upper conveying device and the lower conveying device is large, the tire is easily misaligned with the hub at the preset position during the preparation and downward conveying process, affecting the assembly efficiency.

[0005] By adopting the above technical solution, the wheel hub is conveyed to the preset position, and the tire conveying device conveys the tire between the two upper swing arms. The driving cylinder body is hinged to the frame, and the driving cylinder drives the driving arm and the driving shaft to move. The driving arm drives the rotating shaft to rotate through the connecting rod and the transmission arm. The two upper swing arms of the rotating shaft move away from each other and the two lower swing arms approach each other. The tire then falls downward between the two lower swing arms and is clamped by the two lower swing arms. The driving cylinder then drives the driving arm to rotate in the opposite direction to reset. The driving arm then drives the rotating shaft to rotate in the opposite direction through the connecting rod and the transmission arm. The two upper swing arms move closer to each other and the two lower swing arms move away from each other. The tire falls downward to the wheel hub at the preset position. During the rotation of the driving shaft, the synchronous belt drives the transmission roller and the inclined conveying roller to rotate and convey the tire downward to prevent the tire from stagnating in the tire conveying device.
