DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to make the objectives, technical solutions, and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] Refer to Figures 1 - 4A multi-purpose hole groove detection mechanism for a perforated shaft part as shown, comprising a bottom plate 1 and a cylinder 2. First guide posts 3 are provided at the four corners of the bottom plate 1. A U-shaped frame 4 is slidably connected to the first guide posts 3. A lead screw 5 is rotatably connected to the bottom plate 1. The U-shaped frame 4 is threadedly connected to the lead screw 5. A plurality of second guide posts 6 are provided at both ends of the U-shaped frame 4. Lifting sliders 7 are slidably connected to the second guide posts 6 at each end of the U-shaped frame 4. Springs 701 are provided on the second guide posts 6 between the lifting sliders 7 and the bottom plate 1. A detection pressing plate 8 is slidably connected to the lifting slider 7. A plurality of detection jacks 801 are opened on the detection pressing plate 8. A seat plate 201 is fixedly connected to the piston rod of the cylinder 2. A slotted hole is opened on the seat plate 201. A first limiting rod 202 is slidably connected to the slotted hole. A second limiting rod 101 is fixedly connected to the bottom plate 1. A detection rod 9 is inserted into the detection pressing plate 8.

[0018] The plurality of detection jacks 801 are linearly arrayed on the detection pressing plate 8, and the detection jacks 801 can guide the insertion test of the detection rod 9.

[0019] A relief groove corresponding to the first limiting rod 202 is provided on the bottom plate 1, and the relief groove can make way for the sliding adjustment of the first limiting rod 202. The detection rod 9 is fixedly connected to the seat plate 201 through a bolt assembly, and the bolt assembly is used to lock the position of the detection rod 9.

[0020] Oblique grooves are provided on both the first limiting rod 202 and the second limiting rod 101, and the first limiting rod 202 and the second limiting rod 101 are located in the middle of the U-shaped frame 4. The first limiting rod 202 and the second limiting rod 101 are used for

[0021] A retaining ring is fixedly connected to the middle section of the detection rod 9.
