A method for using the precision auxiliary positioning device for a double-station gear making machine tool according to claim 9, characterized in that: The steps include: Step 1: insert the separate turning frame module (5) into the insertion channel (41) through the slot latch (51); Step 2, start the first drive motor (47), the long power arm (43) rotates counterclockwise, the long power arm (43), the lever fulcrum shaft (42) and the short clamping arm (44) form a labor-saving lever structure, the length of the long power arm (43) is greater than the length of the short clamping arm (44), and when the power is constant, the positioning clamping plate (45) at the front end of the short clamping arm (44) strengthens the fixation of the card slot latch (51); Step 3, the hydraulic pump (6) is started, and the height of the separate turning frame module (5) entering the double-station precision machining chamber (3) is adjusted by means of the hydraulic telescopic frame (61); Step 4, start the second drive motor (73) to drive the first slide (74) and the positioning seat (4) and the separate turning frame module (5) on the first slide (74) to move forward. During the movement, the grinding module (8) is controlled to be intermittently powered off to eliminate the magnetism of the electromagnetic seat (82). The spring (83) is in an extended state. The top and bottom plate grinders (84), the short grinders (85) and the long grinders (86) are in contact with the inner wall of the first slide groove (71) for grinding to ensure that the inner wall of the first slide groove (71) is smooth. Step 5: After the separate turning frame module (5) enters the double-station precision machining chamber (3), the double-station precision machining chamber (3) starts to operate, and the separate turning frame module (5) starts to operate to produce gear parts; Step 6: During the gear production process, the gravity center sensor at the bottom of the second slide (93) serving as a counterweight senses the gravity center information of the separate turning frame module (5) in real time, and the third drive motor (9) is started to drive the second slide (93) to move forward and backward to adjust the gravity center of the separate turning frame module (5), thereby ensuring the stability of the operation of the separate turning frame module (5).
