The utility model relates to automatic processing equipment, in particular to an eccentric shaft angular positioning device which comprises a fixed base, a motor is fixed on one side of the fixed base, a tip is fixed on the fixed base on the opposite side of the motor, and a three-jaw chuck is fixedly connected on 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 tip. The first outer circle and/or the second outer circle of the eccentric shaft to be positioned are/is detected and positioned through more than one airtightness detection assembly. Compared with the prior art, angular positioning of parts with angular positioning requirements can be achieved 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 improved, and on the other hand, the influence of impurities such as s
