Fourth step: after the front beam to be tested is in place, the electric guide rail assembly (21) is used for driving the translation detection seat (22) to move to one end of the top of the detection frame (2), the miniature telescopic cylinder (24) is started, the measuring head of the detector (23) is contacted with the positioning detection rod by utilizing the rod body of the miniature telescopic cylinder (24), and at the moment, the contact condition of one end of the front beam to be tested is recorded; and similarly, after the detector (23) moves to the other end, recording the contact condition of the other end, and after the measurement of the main pin holes at the two ends is finished, operating the surface contact condition of the measuring head and the front beam to be measured to obtain a group of numerical values, and judging the bending condition of the front axle through angle and position information reflected by different numerical value scales.
