The front end of the rotating shaft 13 is fixedly installed with a turntable 14, and the front side of the turntable 14 is fixedly installed with a mounting column 15. The surface of the mounting column 15 is slidably connected with a movable frame 16. The movable frame 16 is fixedly connected to the movable plate 17 to provide driving force for the up and down movement of the movable plate 17. The guide assembly includes a slider arranged on the rear side of the movable plate 17 18. The slider 18 is a T-shaped structure. The slider 18 is made of metal. The surface of the slider 18 is slidably connected to a slide rail 19. The slide rail 19 is fixedly connected to the movable frame 11 to facilitate the up and down movement of the movable plate 17. By cooperating with the driving component and the guide component, the movable plate 17 can be periodically moved up and down, so that the extrusion cylinder 20 can periodically squeeze the spring. A support leg 21 is fixedly installed at the bottom of the base 1. The number of support legs 21 is multiple. The fatigue detection device for spring production is to put the spring on the fixed column 3, and then make the bottom end of the spring contact with the placement table 2. The lifting component is used to move the cylinder 7 upward to a suitable height, and the moving component is used to move the extrusion cylinder 20 forward to a suitable position. By cooperating with the driving component and the guide component, the extrusion cylinder 20 is periodically moved up and down, thereby periodically squeezing the spring, thereby detecting the fatigue of the spring. The fixed column 3, the cylinder 7, and the extrusion cylinder 20 can block the spring, thereby preventing the spring from bouncing, thereby making the fatigue detection of the spring safer.

[0024] Specifically, the lifting assembly includes an electric push rod 4 arranged inside the base 1, a movable plate 5 is fixedly installed on the output end of the electric push rod 4, a mounting plate 6 is fixedly installed on the top of the movable plate 5, and the mounting plate 6 is fixedly connected to the cylinder 7, which is convenient for adjusting the height of the cylinder 7.

[0025] Specifically, the moving component includes a linear motor 8 arranged on the top of the base 1, a moving seat 9 is provided on the linear motor 8, the moving seat 9 is fixedly connected to the moving frame 11, and a baffle 10 is fixedly installed on the top of the linear motor 8 to provide driving force for the forward and backward movement of the moving frame 11, thereby facilitating the adjustment of the forward and backward position of the moving frame 11.

[0026] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device that performs control such as a computer.

[0027] When in use: put the spring on the fixed column 3, then make the bottom end of the spring contact with the placement table 2, then start the electric push rod 4, make the movable plate 5 move upward, make the mounting plate 6 move upward, drive the cylinder 7 to move upward to a suitable height, make the linear motor 8, make the movable seat 9 move forward, drive the movable frame 11 to move forward, and can drive the extrusion cylinder 20 to move forward until the movable seat 9 contacts the baffle 10, then start the drive motor 12, make the rotating shaft 13 rotate, make the turntable 14 rotate, make the mounting column 15 rotate with the turntable 14, so that the mounting column 15 is in the movable frame 16 moves relatively left and right inside, so that the movable plate 17 and the slider 18 move up and down periodically along the slide rail 19, driving the extrusion cylinder 20 to move up and down periodically, thereby periodically squeezing the spring, so as to detect the fatigue of the spring. When the spring needs to be taken out, the linear motor 8 is started to move the movable seat 9 backward, driving the movable frame 11 to move backward, which can drive the extrusion cylinder 20 to move backward to a suitable position, and then the electric push rod 4 is started to move the movable plate 5 downward, so that the mounting plate 6 and the cylinder 7 move downward to a suitable height, and then the spring can be taken out from the fixed column 3.
