Tire changer, also called tire changer, tire picker, is used to install and unload car tires. It can change tires for different vehicles such as cars, motorcycles and heavy trucks. It is a necessary equipment for auto repair shops and 4S shops. There are two types of pneumatic and hydraulic, the most commonly used is pneumatic.
1. Main machine workbench: The tires are mainly dismantled on this workbench, which is mainly used for placing tires and rotating.
2. Separation arm: On the side of the tire disassembling machine, it is mainly used to separate the tire from the rim, which is the smooth process of tire disassembly.
3. Inflating and deflating device: It mainly releases the air of the tire to facilitate inflation or disassembly. In addition, there is a barometer that measures the air pressure. General tires are around 2.2 atmospheres. It is also equal to 0.2Mpa.
4. Foot pedal: There are 3 foot pedal switches under the tire changer, which are used to rotate the switch clockwise and counterclockwise, separate the tightening switch, separate the rim and the tire switch.
5. Lubricating fluid: It is convenient for disassembling and disassembling the tire, reducing the damage during the disassembling of the tire, and making the tire disassembly and assembly work better.
6. Compressed air interface.
There are two main types of tire changers on the market, one is a small vertical tire changer for dismounting car tires; the other is a large horizontal tire changer for dismounting large truck tires. machine.
The main structure of a common large tire changer is mainly composed of a power unit, an oil cylinder, a support arm, a claw, a pick-off head, and an operating table. There are three cylinders in the structure to complete the movement through the hydraulic system. One is to support the pawl to open and retract the cylinder to clamp and loosen the tire. The other is to support the support arm to rotate the cylinder to lift and lower the tire. Support the head part to move the cylinder back and forth to complete the tire installation and removal.
In the entire operation process, basically automatic operation has been realized, but part of the operation of the steak head still needs to be completed by manual operation, which increases the labor intensity. If the operation of the steak head part can also be completed by the hydraulic system, it will greatly Reduce labor intensity and fully realize equipment automation.
