2) And (3) measuring: after positioning, the top of the point a positioning column (4) is tightly attached to the lift surface of a spring seat of the oil storage barrel assembly, the through end and the stop end of the first gauge block (6) are used for detecting a detection section formed by the lower end surface of the oil storage barrel assembly and the measuring base (7), and the through and stop qualification judgment size is qualified; the spring seat positioning hole measuring column (14) slides upwards, and if the spring seat positioning hole measuring column (14) can penetrate into a spring seat positioning hole on the spring seat, the welding rotation direction size of the spring seat is judged to be qualified; the lifting surface of the spring seat is tightly attached to the point b measuring column (10), the point c measuring column (13) and the point d measuring column (16) under the action of the spring (12), the through-return end and the stop-return end of the second gauge block (8) are used for detecting a detection section formed between the lower measuring end surface of the point b measuring column (10), the point c measuring column (13) and the point d measuring column (16) and the measuring base (7), and the through-stop-return qualified judgment size is qualified.
