The invention discloses a tire ring splitting
machine. The tire ring splitting
machine comprises a
machine bod, a positioning mechanism and a ring splitting mechanism, wherein the ring splitting mechanism comprises a first fixing part, a second fixing part, a first
cutting knife, a second
cutting knife and an inner ring fixing
assembly, the first fixing part and the second fixing part are arrangedat an interval, the first fixing part can move towards the position close to or away from the second fixing part in the axial direction of the first fixing part, the inner ring fixing
assembly is connected in the second fixing part in a penetrating mode and is pivoted to the machine body, the inner ring fixing
assembly is used for being inserted into the inner periphery of an inner ring of a tireand abutting against the inner periphery of the inner ring of the tire when the positioning mechanism moves to a ring splitting
station, the first fixing part is used for fixing the tire on the innerring fixing assembly to move towards the position close to the second fixing part so as to enable the tire to be clamped between the first fixing part and the second fixing part, the first
cutting knife is arranged on the machine body, and the second cutting knife is arranged on the machine body. According to the tire ring splitting machine, the inner ring and the outer ring of the tire can be separated.
