Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", and the like, indicate positional or positional relationships, are merely for convenience in describing the present invention and to simplify the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

As shown in fig. 1-4, a spring 15 detection device includes: the feeding guide rail, the feeding support 1, the supporting plate 6 and the detection mechanism; the feeding guide rail extends to the feeding support 1, the feeding support 1 is connected with a plurality of vertically arranged compression bars 2 in a sliding manner, the feeding support 1 is provided with a plurality of feeding holes, and the projections of the feeding holes in the vertical direction fall on the supporting plate 6; a plurality of cup enlargers 5 are arranged on the supporting plate 6, and the cup mouths of the cup enlargers 5 are upward; the detection mechanism is arranged below the supporting plate 6 and comprises a frame 13, a gauge 16 and a measuring column 18; the gauges 16 have a through hole running through them in common, the measuring column 18 is arranged vertically directly below the through hole, the diameter of the through hole is equal to the design value of the outer diameter of the spring 15, the diameter of the measuring column 18 is equal to the design value of the inner diameter of the spring 15, and the height of the measuring column 18 is greater than the length of the spring 15.

The working principle of the measuring device of the present invention is described in detail below, in the detecting process, the formed spring 15 falls into each of the flaring cups 5, and when passing through the feeding rack 13, the spring 15 is further pressed into the flaring cup 5 by the pressure bar 2, so as to facilitate the orderly transmission of the spring 15. The spring 15 in the beaker 5 is then removed and transferred to a gauge 16, wherein the gauge 16 has an internal diameter equal to the design value of the external diameter of the machining spring 15. Thus, if the outer diameter of a certain section of the spring 15 is larger than the designed diameter, the spring is caught at the through hole of the gauge 16 and does not completely fall into the through hole when entering the gauge 16. Thus, it is possible to determine whether the outer diameter of the spring 15 is large, and when the outer diameter is large and the thickness of the spring 15 is constant, it is possible to directly estimate that the inner diameter is large.

In contrast, if the spring 15 can smoothly pass through the through hole, the outer diameter of the spring 15 is equal to or smaller than the inner diameter of the through hole. In order to further determine whether the outer diameter and the inner diameter of the spring 15 are small, it is necessary to observe the positional relationship between the spring 15 and the measuring cylinder 18. Since the spring 15 is still in a vertical state when it is released from the gauge 16, if the lower end of the spring 15 can fall down to the lower end of the measuring column 18, the inner diameter of the spring 15 becomes smaller, and the spring is caught on the measuring column 18 during the falling.
