[0022] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0023] like Figure 1-4 As shown, the utility model provides a technical solution: a spring fatigue detection device for automobile spring production, comprising a mounting plate 1, a base 2 is fixedly installed at the bottom of one side of the mounting plate 1, a mounting seat 3 is fixedly installed on the top of the base 2, and a rotating bottom plate 4 is rotatably installed on the side of the mounting seat 3 away from the mounting plate 1, and a mounting rod 5 is fixedly installed at the central position of the top of the rotating bottom plate 4. By providing the rotating bottom plate 4, after the spring to be detected is placed on the top of the rotating bottom plate 4, the rotating bottom plate 4 is controlled to rotate, so that the spring to be detected can be vertically placed on the top of the rotating bottom plate 4, which is convenient for measuring the length of the spring to be detected when it is placed vertically;

[0024] A fixed end block 6 is fixedly installed at one end of the mounting rod 5 away from the rotating base plate 4, and a fixed socket 7 is provided at one end of the fixed end block 6. Because of the mounting rod 5, the spring to be tested is sleeved on the surface of the mounting rod 5 to ensure that the spring to be tested will not fall off the top of the rotating base plate 4 and tip over during testing.

[0025] The mounting plate 1 is located on the top of one side of the base 2 and is fixedly installed with a mounting card 8; two groups of mounting columns 9 are fixedly installed on the top of the mounting card 8, and connecting end plates 10 are fixedly installed on the tops of the two groups of mounting columns 9, and a clamping plate 11 is slidably installed on the surface of the two groups of mounting columns 9 located on the top of the mounting card 8, and a fixed clamping column 12 is fixedly installed inside the bottom of the clamping plate 11 on the side of the mounting card 8 away from the mounting plate 1, and the fixed clamping column 12 corresponds to the fixed socket 7. By providing the clamping plate 11 and the fixed clamping column 12, after the fixed end block 6 is inserted into one side of the mounting card 8, the clamping plate 11 is pressed against the top of the mounting card 8 to ensure that the fixed clamping column 12 can be inserted into the corresponding fixed socket 7, thereby clamping and fixing the mounting rod 5 to ensure that the rotating base plate 4 will not rotate at will on the top of the mounting seat 3.

[0026] A clamping spring 13 is provided on the surface of the mounting column 9 located at the top of the clamping plate 11, and a support seat 14 is fixedly installed at the bottom of the mounting plate 1 away from the base 2. Because of the clamping spring 13, the clamping plate 11 is pressed against the top of the mounting clamping plate 8 under the rebound action of the clamping spring 13, ensuring that the fixed clamping column 12 at the bottom of the clamping plate 11 can clamp and fix the fixed end block 6.

[0027] A rotating motor 19 is fixedly installed on the top of the support seat 14, and two groups of mounting blocks 15 are fixedly installed on the mounting plate 1 on one side of the support seat 14. A rotating screw 16 is rotatably installed at the central position between the two groups of mounting blocks 15, and limiting slide bars 17 are symmetrically fixedly installed on both sides of the rotating screw 16 between the two groups of mounting blocks 15. By providing the rotating screw 16 and the limiting slide bars 17, the rotating screw 16 is rotated to control the moving seat 20 to slide on the surfaces of the rotating screw 16 and the two groups of limiting slide bars 17, thereby ensuring that the moving seat 20 will not deflect during the movement.

[0028] A moving seat 20 is provided on the surface of the rotating screw 16 and the two sets of limiting slide bars 17. A moving pressure plate 21 is fixedly installed on both ends of one side of the moving seat 20 through the mounting plate 1. Pressure sensors 22 are symmetrically fixedly installed on both sides of the bottom of the moving pressure plate 21, and the pressure sensor 22 corresponds to the rotating base plate 4. Because the pressure sensor 22 is provided, when the moving seat 20 drives the moving pressure plate 21 to move up and down, the pressure sensor 22 moves on the top of the spring to be detected. When the pressure sensor 22 contacts the spring to be detected, the pressure sensor 22 transmits a stop signal to the rotating motor 19, so that the moving pressure plate 21 stops at the top of the spring to be detected in time.

[0029] A bevel gear 18 is fixedly installed at the output end of the rotating motor 19, and a bevel gear 18 is fixedly installed at the bottom end of the rotating screw 16 through the rotating screw 16, and the two sets of bevel gears 18 are meshed with each other. By providing the bevel gears 18, the rotating motor 19 is started to control the two sets of bevel gears 18 to rotate synchronously, thereby driving the rotating screw 16 to rotate and control the moving seat 20 to move up and down.

[0030] The working principle of the utility model is:

[0031] When the movable pressure plate 21 is located at the top of the mounting plate 1, the spring to be detected is sleeved on the surface of the mounting rod 5, the clamping plate 11 is lifted to make the fixed clamping column 12 away from the mounting clamping plate 8, the mounting rod 5 is rotated to make the fixed end block 6 clamped into the inside of the mounting clamping plate 8, the clamping plate 11 is loosened, and the fixed clamping column 12 is clamped into the inside of the fixed socket 7 under the rebound action of the clamping spring 13, the rotating motor 19 is started to control the rotating screw 16 to rotate, so that the moving seat 20 drives the moving pressure plate 21 to slide down on the surface of the rotating screw 16 and the two sets of limit slide bars 17 until the pressure sensor 22 contacts the bottom of the spring to be detected, the rotating motor 19 is controlled to stop, and the distance between the rotating bottom plate 4 and the moving pressure plate 21 is measured, so as to measure the vertically placed length of the spring to be detected.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0033] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
