Abstract:
The present invention discloses a tire disassembly and assembly booster arm device installed on an upright of a tire disassembly and assembly machine. The tire disassembly and assembly booster arm device includes a first tire pressing arm and a second tire pressing arm. A first polished shaft and a second polished shaft are symmetrically arranged on two sides of the upright. An air cylinder hanging frame is installed on the top surface of the upright, and an air cylinder is suspended on the air cylinder hanging frame. One end of a piston rod of the air cylinder is connected to a sliding frame connecting frame. A first sliding frame is connected to the first polished shaft in a sliding mode. The front end of the first sliding frame is hinged to the first tire pressing arm, and the rear end of the first sliding frame is connected to one side of the sliding frame connecting frame. A second sliding frame is connected to the second polished shaft in a sliding mode. The front end of the second sliding frame is hinged to the second tire pressing arm, and the rear end of the second sliding frame is hinged to the other side of the sliding frame connecting frame. The tire disassembly and assembly booster arm device may drive the first tire pressing arm and the second tire pressing arm to descend at the same time, so that a tire is pressed to be separated from a hub, which has convenient operations, realizes an assisting mode of one cylinder with two arms, and has the advantages of simple structure, easy for disassembly and assembly, improves work efficiency, and reduces manufacturing and transportation cost.
