The invention relates to automatic machining equipment, in particular to an eccentric shaft angular positioning device which comprises a fixed base. A motor is fixed to one side of the fixed base, a center is fixed to the position, at the opposite side of the motor, of the fixed base, and a three-jaw chuck is fixedly connected to a motor shaft of the motor; one end of an eccentric shaft to be positioned is clamped on the three-jaw chuck, and the other end of the eccentric shaft to be positioned abuts against the center; and the first outer circle and the second outer circle of the eccentric shaft to be positioned are respectively detected and positioned through one air tightness detection assembly. Compared with the prior art, the eccentric shaft angular positioning device can achieve angular positioning of parts with angular positioning requirements with low cost, a plurality of airtight assemblies can be set according to different workpieces, on one hand, the stability and reliability of a system are improv
