As shown in fig. 2-3, the utility model discloses a rapid detection tool for straightness and drop of an 8T front beam as shown in fig. 2, which is characterized in that a middle rod detection mechanism 7 is fixedly arranged in the middle position of the upper surface of a cuboid-shaped detection tool platform 10, a set of plate seat detection mechanisms 6 are symmetrically and fixedly arranged on the left side and the right side of the middle rod detection mechanism, and a shaft head detection mechanism is slidably arranged on the outer side of each set of plate seat detection mechanism. The three sets of inspection mechanisms are all of symmetrical structures, and the center line of each mechanism is arranged in line with the front center line and the rear center line of the inspection tool platform. The middle rod inspection mechanism, the plate seat inspection mechanism and the V-shaped clamping seat are all arranged perpendicular to the inspection tool platform.
The straightness of the middle rod is detected by detecting the two side faces of the middle rod during front beam detection, so that the middle rod detection mechanism is of a semi-open structure with a U-shaped longitudinal section, an opening at the upper part of the U-shaped is a clamping interface during middle rod detection, the middle rod is clamped and fixed on the detection tool through the clamping interface, and two side plates of the semi-open structure are symmetrically arranged about the center line of the detection tool platform 10. And the integral straightness condition of the front beam is judged by measuring the gap difference between the two side surfaces of the front Liang Zhonggan and the two side plates of the U-shaped structure, wherein the required straightness is less than or equal to 2mm, namely the gap difference between the two side surfaces is less than or equal to 4mm.
The board seat inspection mechanism is a semi-open structure with a U-shaped longitudinal section formed by two inspection blocks, and an opening at the upper part of the U-shaped is a clamping interface during board seat test. The straightness of the position of the front beam plate seat can be judged by measuring the gap difference between the two side plates of the front beam plate seat and the checking fixture plate seat checking block (the gap difference is less than or equal to 4 mm).
One side of the two sets of shaft head inspection mechanisms, which is close to the plate seat inspection mechanism, is provided with a V-shaped clamping seat 4, and the height of the V-shaped clamping seat is higher than that of the middle rod inspection mechanism and the plate seat inspection mechanism.
