The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0067] Embodiment 1: A continuity detection device for a columnar part, such as Figure 1-8 As shown, it includes a mounting base 1, on which a conveyor chain conveying mechanism for conveying columnar parts 38 is mounted, and a diameter detection mechanism and a length detection mechanism are arranged on the conveying path of the conveyor chain conveying mechanism, and the conveyor chain conveying mechanism includes:

[0068] The first conveying chain 3 has two sets of first sprocket wheels rotatably mounted on the mounting base 1 through shafts, and the two first conveying chains 3 are symmetrically mounted on the two sets of first sprocket wheels;

[0069] A first connecting frame 14, both ends of which are respectively mounted on the two first conveying chains 3, a plurality of first connecting frames 14 are equidistantly arranged, and a plurality of linearly distributed V-shaped plates 27 are arranged on the first connecting frame 14;

[0070] The first chain drive motor 2 is installed on the mounting base 1, and is used to drive the first sprocket to move and then drive the first conveying chain 3 to move; wherein, the first chain drive motor 2 can be set to two according to the needs, so as to better drive the two groups of first sprockets to move synchronously, or only one first chain drive motor 2 is used, and a large-sized first sprocket is used at the same time, and the two groups of first sprockets are coaxially connected in pairs, and the radius of the first sprocket should be greater than the effective length of the V-shaped plate 27 to facilitate its smooth passage; in addition, the accompanying drawings are only for exemplary purposes, and the wrap angle between the first sprocket and the first conveying chain 3 should meet the transmission requirements, and a tensioning structure can be set on the motion trajectory of the first conveying chain 3, etc., to improve the transmission effect and conveying stability, which will not be elaborated here;

[0071] The diameter detection mechanism comprises:

[0072] An annular plate 8, the annular plate 8 is mounted on the mounting base 1;

[0074] The dial plate 39 is mounted on the rotating rod 40. A diameter detection channel for the dial plate 39 to pass through is provided between the V-shaped plates 27 of the first connecting frame 14. The top of the dial plate 39 extends to the movement path of the diameter detection channel;

During the process, the columnar part 38 contacts the paddle plate 39 and causes the paddle plate 39 to deflect, and the angle sensor detects the deflection angle; since the V-shaped plate 27 is a V-shaped structure with a fixed angle and symmetry, when columnar parts 38 of different diameters are placed in the V-shaped plate 27, the heights of their centers are different, which leads to different heights of their bottom surfaces. Therefore, based on the position of the bottom surface, By detecting the position of the lever 39, the diameter of the columnar part 38 can be obtained.
