The invention provides a swinging detector of an automobile shock absorption ring. The swinging detector comprises a shock absorption ring conveying mechanism, a shock absorption ring transporting and clamping mechanism, a 360-degree rotation mechanism, a front-back swinging mechanism, a left-right swinging mechanism, a qualified product dotting marking and discharging mechanism, wherein the shock absorption ring transporting and clamping mechanism is used for conveying the product to all detection mechanism positions, so that the shock absorption ring is detected at all the detection mechanism positions; when the product is qualified, the product is conveyed out of the detector through the qualified product dotting marking and discharging mechanism. The swinging detector can simulate a manual operation process, manpower labor is released and industrial standards are established. Furthermore, the labor intensity of swinging workers is great so that the swinging workers cannot work contentedly and the post loss is serious; and the swinging detector completely replaces the manual operation and completely eliminates artificial factors; the product is detected according to a certain process and can be traced and can be produced and used according to the standards. Reversely, the swinging detector has great significance of facilitating a rubber molding process, a series of production reformation including raw material detection and the like.
