Tire disassembly and assembly assisting arm device

Abstract

The invention discloses a tire disassembly and assembly assisting arm device installed on an upright of a tire disassembly and assembly machine. The tire disassembly and assembly assisting arm devicecomprises a first tire pressing arm and a second tire pressing arm. A first polished shaft and a second polished shaft are symmetrically arranged on the two sides of the upright. An air cylinder hanging frame is installed on the top face of the upright. An air cylinder is suspended on the air cylinder hanging frame. One end of a piston rod of the air cylinder is connected with 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. The rear end of the first sliding frame is connected with 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. The rear end of the second sliding frame is connected with the other side of the sliding frame connecting frame. The tire disassembly and assemblyassisting arm device can 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, operation is convenient,an assisting mode that one air cylinder drives the two arms is achieved, the structure is simple, disassembly and assembly are convenient, work efficiency is improved, and manufacturing cost and transporting cost are reduced.

Description

technical field [0001] The invention relates to the technical field of tire disassembly and assembly, in particular to a tire disassembly and assembly assist arm device. Background technique [0002] Traditional tire changers are generally equipped with a booster arm on the swing arm, on the column lugs, on both sides of the main box or on both sides of the main box, and each booster arm is respectively equipped with one cylinder and one valve. , not only the structure is complicated and the space occupied is large, but also because the left and right booster arms cannot be adjusted and used at the same time, the heights of the left and right booster arms need to be manually adjusted each time the run-flat tire is put on, which is inconvenient to operate and wastes manpower. [0003] In addition, there is another way to install the booster arm: install a skateboard behind the column of the tire changer, install sliders on both sides of the skateboard, and install a booster a...

Problems solved by technology

[0002] Traditional tire changers are generally equipped with a booster arm on the swing arm, on the column lugs, on both sides of the main box or on both sides of the main box, and each booster arm is respectively equipped with one cylinder and one valve. , not only has a complex structure and takes up a large space, but also because the left and right booster arms cannot be adjusted and used at the same time, it is necessary to manually adjust the heights of the left and right booster arms each time the run-flat tire is put on, which is inconvenient to operate and wastes manpower.

[0003] In addition, there is another way to install the booster arm: install a skateboard behind the column of the tire changer, install sliders on both sides of the skateboard, and install a booster arm frame outside the slider to install the booster. Arms are added layer by layer from the column to the rear, so that the cylinder can only be installed on the main chassis. Although the two booster arms can work at the same time, the volume of the device is too large, which increases the manufacturing cost. It is not only inconvenient to operate, but also reduces the work efficiency, and due to the complex structure, which cannot be disassembled, the transportation cost is too high
