The invention provides a counterweight blade double-station milling machining alignment method. The counterweight blade double-station milling machining alignment method comprises the following stepsthat S1, a clamp is mounted on an A-axis transition disc of a machining center, a clamping datum plane of a clamp body faces the forward direction of the Z axis, jumping of the clamping datum plane onthe clamp body is measured, and meanwhile the angle of the A axis is adjusted continuously till jumping of the datum plane is within a set threshold value; S2, a first blade blank is mounted on a first station of the clamp body; S3, feature machining of a blade root on the first station is completed; S4, a second blade blank machined in the step S3 is detached and then clamped on a second stationof the clamp body; S5, a line measuring probe is used for automatic alignment of the second station; and S6, after alignment, machining of a blade molded surface and a blade profile and blade root adapting face is completed by
