Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a high-efficiency high-stability nut detection method and a jig comprise a bottom plate 1, a top support 2 of the bottom plate 1, a cross rod 3 fixedly connected to the middle of one side of the support 2 opposite to the top support, a clamping block 4 clamped in the middle of the cross rod 3, a support rod 5 arranged at the bottom of the clamping block 4, a metal detector 6 fixedly connected to the bottom of the support rod 5, a detection meter 7 fixedly connected to the right side of the clamping block 4, a central shaft 8 fixedly connected to the middle of the top of the bottom plate 1, support plates 9 fixedly connected to both sides of the top of the bottom plate 1, a spring 10 fixedly connected to the middle of one side of the support plates 9 opposite to the spring 10, a clamp 11 fixedly connected to the other end of the spring 10, a pressure sensor arranged on a spring 10 body, when a hexagon nut is sleeved on the central shaft 8, the pressure sensor, then detect table 7 and convert the signal into data display through the signal that the inductor sent, and then can record hexagon nut's width, hexagon nut suit closely laminates with the inner wall of anchor clamps 11 when 8 outer lanes in the center pin, can avoid the testing result not accurate, center pin 8 and anchor clamps 11 are non-metallic material, the nut is the metal material, metal inductor 6 is located center pin 8 directly over, can detect whether there is the metal to exist, anchor clamps 11's inside is provided with the second metal inductor, a height for surveying induction nut.
