[0015] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0016] See also Figure 1 and Figure 2 FIG. 1 is an embodiment of the nut flatness detection device of the present application, which mainly includes an imaging base 1, an imaging support frame 2, a first line scan camera bracket 3, a first line scan camera small board 4, a second line scan camera bracket 5, a second line scan camera small board 6, a first camera 7, and a second camera 8.

[0017] The image support frame 2 is connected to the image base 1, and the image support frame 2 is connected to the first camera 7 through the first line scan camera support 3 and the first line scan camera small board 4, and is connected to the second camera 8 through the second line scan camera support 5 and the second line scan camera small board 6. The first camera 7 and the second camera 8 can thereby achieve the purpose of adjusting the detection range and the shooting angle.

[0018] The imaging base 1 is fixed on a workbench by bolts, so a plurality of bolt holes are provided on the imaging base 1. A raised slide rail 11 is provided on the imaging base 1.

[0019] The image support frame 2 is connected to the image base 1. Figure 1 and Figure 2 As shown, the image support frame 2 includes an image rod 21, a first slider 22, a second slider 23, a third slider 24, a first adjustment shaft 251, a first hand wheel 252, a second adjustment shaft 253, a second hand wheel 254, a third adjustment shaft 255 and a third hand wheel 256.

[0020] The bottom of the image rod 21 is connected to an image rod bottom plate 211, and the image rod bottom plate 211 is fixed on the third slider 24, and the third slider 24 is connected to the image base 1 through the third hand wheel 256 and the third adjustment shaft 255. The image rod 21 can thus adjust the overall position of the image rod 21 along the slide rail 11 on the image base 1. The image rod 21 is provided with a vertical slide rail 211.

[0021] The first slider 22 is connected to the slide rail 211 on the image rod 21 through the first adjustment shaft 251 and the first hand wheel 252. The first line scan camera bracket 3 is connected above the first slider 22. The first line scan camera bracket 3 is provided with a first line scan camera small board 4, and the inner end of the first line scan camera small board 4 is connected to the first line scan camera bracket 3, so that the first line scan camera small board 4 can move horizontally along the inner end (fixed end) relative to the first line scan camera bracket 3. The first camera 7 is connected to the first line scan camera small board 4. In this way, the first camera 7 adjusts the shooting angle and range with the horizontal movement of the first line scan camera small board 4 and the vertical movement of the first slider 22.

[0022] The second slider 23 is connected to the slide rail 211 on the image rod 21 through the second adjustment shaft 253 and the second hand wheel 254. The second slider 23 is located above the first slider 22. The second slider 23 is connected to the second line scan camera bracket 5 below. The second line scan camera bracket 5 is connected to the inner end (fixed end) of the second line scan camera small board 6 below, so that the second line scan camera small board 6 can rotate horizontally relative to the second line scan camera bracket 5 along the fixed end. The second camera 8 is connected to the second line scan camera small board 6 below. In this way, the second camera 8 adjusts the shooting angle and range with the horizontal movement of the second line scan camera small board 6 and the vertical movement of the second slider 23.

[0023] In addition, if Figure 2 As shown, the length of the first line scan camera bracket 3 is longer than the length of the second line scan camera bracket 5. In this way, in the folded state, the first camera 7 and the second camera 8 can be on the same horizontal line, and the shooting angles can overlap.
