[0016] like Figures 1 to 3As shown, an auxiliary tool for detecting outer diameter runout includes a guide rail base main structure 1, the upper end of the guide rail base main structure 1 is provided with a sliding matching groove, and two groups of main support bases 2 that can be slidably matched and opposite in direction are installed in the sliding matching groove, and can be flexibly moved and operated according to needs when in use. The upper end of the main support base 2 is connected to a detachable detection reference matching seat 3, and a bearing structure 4 is provided on the side of the detection reference matching seat 3, which can provide smooth and stable activity matching for the detection component. A detection matching rotor structure 5 is installed at the center position of the bearing structure 4, and the detection end of the detection matching rotor structure 5 is a conical structure. When performing detection, the tips of the conical structures on both sides cooperate with the outer diameter position of the step shaft to be detected to detect the runout. A positioning and fastening matching hole is provided between the main support base 2 and the guide rail base main structure 1, so that the measuring tool can be fixed in position during the detection process, ensuring better safety during detection. When in use, the main detection position of the measuring tool is set on a movable guide rail assembly, which makes the moving operation during detection more convenient and can keep the horizontal alignment of the center line of the detection position during movement. When detecting, by assembling the rotor on the bearing assembly, it can ensure smooth rotation during detection, and the overall stability during rotation is more reliable, which saves effort during detection and can ensure the placement accuracy of the matching with the step shaft to be detected, so that the detection data is more accurate, the operation during detection is more convenient, and the detection efficiency is higher.
[0017] Preferably, the detection reference matching seat 3 is connected to the main body support base 2 through a threaded fastening assembly 6, which makes the matching operation more convenient during fastening and has a lower component cost.
[0018] Preferably, the main support base 2 and the guide rail base main structure 1 are provided with an anti-falling combined matching structure at the matching position, such as a matching groove structure that is narrow at the top and empty at the bottom, which can make the combination between them safer.
[0019] Preferably, the outer end surface of the detection reference matching seat 3 in the movable direction is on the same plane as the outer end surface of the corresponding position of the main body support base 2, so that the flatness of the outer structure is better and the safety is better during use.
[0020] Preferably, both ends of the guide rail base main structure 1 in the length direction are provided with anti-drop components to prevent the main support base 2 from moving and falling. When moving and cooperating, the movement safety during use is higher and it is prevented from falling when moving to the maximum position.
