Tyre dismounting and balancing integration machine

The invention provides a tyre dismounting and balancing all-in-one machine which is characterized in that a connection-separation transmission gear is also arranged, wherein power equipment of a dismounting machine, power equipment of a balancing machine, and power equipment of the connection-separation transmission gear are arranged on a box body, a wheel fixing device is used for fixing a revolving part on a main shaft, the box body is pin-jointed with a base and can rotate by 90 degrees relative to the left or the right of the base; and an air cylinder is fixedly connected with the base and the box body. Due to the adoption of such a structure, the connection-separation transmission gear realizes the engagement and the separation of the power equipment of the dismounting machine and the power equipment of the balancing machine, and realizes the function of dismounting the tyre in the engaging process; the box body rotates by 90 degrees, and the function of balancing the tyre is realized in the separating p
