Double-shaft indexing mechanism with double shafts locked independently

A double-shaft indexing mechanism with double shafts locked independently is characterized in that an outer ring base and an inner ring frame are respectively provided with a set of driving locking kit, each driving locking kit comprises a locking assembly and a driving assembly, the driving assembly on the outer ring base is used for driving the inner ring frame to rotate forwards and backwards,and the locking assembly on the outer ring base is used for locking and unlocking the inner ring frame; the driving assembly on the inner ring frame is used for driving a load frame to rotate positively and negatively, and the locking assembly on the inner ring frame is used for locking and unlocking the load frame; and one end of the load frame is connected with the locking assembly on the innerring frame, and the other end of the load frame is connected with the driving assembly on the inner ring frame. The problem that an existing vehicle-mounted inertial navigation calibration device cannot reliably lock a certain
