Description

Technical Field

[0001] The utility model belongs to the technical field related to the performance detection of steel wires, and particularly relates to a device for detecting the anti-fatigue performance of flat-section spring steel wires. Background Technique

[0002] Compared with circular-section springs, flat-section springs have the advantages of large energy storage, low compression height, and large compression amount. Therefore, they are widely used in devices with relatively small installation spaces such as engine valve mechanisms, clutches, and automatic transmissions. At the same time, fatigue refers to the fatigue generated by the repeated action of various stresses during use, which gradually deteriorates the physical and mechanical properties of the product, resulting in cracks, heat generation, peeling, damage, etc., and finally losing its service value. And fatigue resistance refers to the ability to withstand the repeated action of stresses. In order to ensure the service life of flat-section springs, it is necessary to use a corresponding anti-fatigue performance detection device to test the anti-fatigue performance of flat-section spring steel wires.

[0003] However, when the existing detection device is in use, since it does not have the function of adjusting the clamping structure, it cannot be freely clamped according to the thickness of the steel wire. And when using the detection device to detect the anti-fatigue performance of spring steel wires, when bending the steel wire, it is impossible to accurately determine the number of times the steel wire is bent. Therefore, it is impossible to quickly determine whether the steel wire has high anti-fatigue performance or low anti-fatigue performance. For this reason, we provide a device for detecting the anti-fatigue performance of flat-section spring steel wires to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for detecting the anti-fatigue performance of flat-section spring steel wires. By controlling the up and down rotation of the screw rod inside the screw barrel, steel wires of different thicknesses can be clamped in the through holes. At the same time, the linkage block bends the steel wire, and the counter counts to quickly determine whether the steel wire has high anti-fatigue performance or low anti-fatigue performance.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a device for detecting the anti-fatigue performance of flat-section spring steel wires, including a test board; two symmetrically arranged linkage blocks are provided on the upper end surface of the test board. Through holes are respectively formed in the front end surfaces of the two linkage blocks. Screw barrels communicated with the inside of the through holes are respectively fixed on the upper end surfaces of the linkage blocks. Screw rods are spirally arranged inside the screw barrels respectively. A bending ring is arranged between the two linkage blocks. An arc-shaped opening is formed through the upper end surface of the test board behind the bending ring. A connecting block is arranged on the lower end surface of the test board corresponding to the arc-shaped opening. Counters are respectively fixed on the left and right ends of the test board. Touch probes electrically connected to the counters are respectively arranged at both ends inside the arc-shaped opening.

[0007] The present utility model is further configured such that rotating plates are fixedly arranged on the upper end surfaces of the screw rods, and cushion blocks are fixedly arranged on the lower end surfaces of the screw rods.

[0008] The present utility model is further configured such that an installation ring bolt - connected to the linkage ring is arranged directly behind the bending ring, and strip - shaped blocks are fixed between the installation ring and the bending ring.

[0009] The present utility model is further configured such that a motor is arranged on the lower end surface of the test plate, and the motor is fixed at the lower end surface position of the test plate through a mounting bracket.

[0010] The present utility model is further configured such that a rotating bar is fixed to the shaft end of the motor, a notch is formed on the lower end surface of the connecting block, and the end of the rotating bar away from the motor is inserted into the notch.

[0011] The present utility model is further configured such that support columns are fixedly arranged at the four diagonal positions on the lower end surface of the test plate, and the heights of the support columns all exceed the height of the mounting bracket.

[0012] The present utility model is further configured such that a sliding rod sliding inside the sliding opening is fixed to the upper end surface of the connecting block, and the sliding rod is in screw connection with the linkage block through a bolt.

[0013] The present utility model has the following beneficial effects:

[0014] 1. When the present utility model is in use, the steel wire is passed through the through - holes of the two linkage blocks, and the screw rod is rotated inside the screw barrel, so that the screw rod clamps the steel wire inside the through - hole. At the same time, since the screw rod moves up and down inside the screw barrel, steel wires with different thicknesses can be clamped in the through - holes.

[0015] 2. When the present utility model is in use, the linkage block behind the bending ring is controlled to slide left and right along the arc - shaped opening. Thus, each time the linkage block comes into contact with the touch probe, the counter will perform a counting process. By counting the number of times the steel wire is bent, it is possible to quickly determine whether the steel wire has high fatigue resistance or low fatigue resistance.

[0016] Of course, when implementing any product of the present utility model, it is not necessarily required to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Embodiment 1

[0027] Please refer to Figures 1 to 5 , the present utility model is a device for detecting the anti-fatigue performance of a flat-section spring wire. By controlling the up-and-down rotation of the screw rod 203 inside the screw barrel 202, steel wires of different thicknesses can be clamped in the through hole 201. At the same time, the linkage block 2 bends the steel wire, and the counter 4 counts to quickly determine whether the steel wire has high anti-fatigue performance or low anti-fatigue performance.

[0028] Specifically, there is a test board 1. On the upper end face of the test board 1, there are two linkage blocks 2 that are symmetrically arranged front and back. Through holes 201 are respectively formed through the front end faces of the two linkage blocks 2. Screw barrels 202 that are connected to the inside of the through holes 201 are fixed on the upper end faces of the linkage blocks 2. Screw rods 203 are spirally arranged inside the screw barrels 202. A bent ring 3 is arranged between the two linkage blocks 2. An arc-shaped opening 102 is formed through the upper end face of the test board 1 behind the bent ring 3. A connecting block 6 is arranged on the lower end face of the test board 1 corresponding to the position of the arc-shaped opening 102. Counters 4 are fixed on the left and right ends of the test board 1. Touch probes 401 that are electrically connected to the counters 4 are arranged at both ends inside the arc-shaped opening 102.

[0029] The operation process of this embodiment is as follows: Through the setting and use of the above structure, when detecting the fatigue resistance performance of the spring wire, the wire is passed through the through holes 201 of the two linkage blocks 2, and the screw rod 203 is rotated inside the screw barrel 202 to clamp the wire inside the through hole 201. At the same time, since the screw rod 203 moves up and down inside the screw barrel 202, wires of different thicknesses can be clamped in the through hole 201. At this time, then control the linkage block 2 behind the bent ring 3 to slide left and right along the arc-shaped opening 102. Thus, each time the linkage block 2 comes into contact with the touch probe 401, the counter 4 will perform a counting process. By counting the number of times the wire is bent, it can be quickly determined whether the wire has high fatigue resistance or low fatigue resistance.

[0030] Furthermore, rotating plates 205 are fixed on the upper end faces of the screw rods 203, and cushion blocks 204 are fixed on the lower end faces of the screw rods 203. An installation ring 301 that is bolt-connected to the linkage ring is arranged directly behind the bent ring 3. A strip 302 is fixed between the installation ring 301 and the bent ring 3. Support columns 101 are fixed at the four diagonal positions on the lower end face of the test board 1. The heights of the support columns 101 all exceed the height of the installation frame. By controlling the rotation of the rotating plate 205, the rotating plate 205 will drive the screw rod 203 to rotate inside the screw barrel 202, and then the screw rod 203 will drive the cushion block 204 to abut against the wire.

[0031] Embodiment 2

[0032] Please refer to Figure 2 and Figure 4 Based on Embodiment 1, the motor 5 drives the connecting block 6 to rotate, which is convenient for driving the linkage block 2 to rotate.

[0033] Specifically, a motor 5 is provided on the lower end surface of the test board 1. The motor 5 is fixed to the lower end surface of the test board 1 through a mounting bracket. A rotating bar 501 is fixed to the rotating shaft end of the motor 5. A notch 602 is formed on the lower end surface of the connecting block 6. The end of the rotating bar 501 away from the motor 5 is inserted into the notch 602. A sliding rod 601 that slides inside the sliding opening is fixed to the upper end surface of the connecting block 6, and the sliding rod 601 is screwed to the linkage block 2 through a bolt.

[0034] The operation process of this embodiment is as follows: To facilitate the control of the rotation of the linkage block 2, the motor 5 can be controlled to work. Thus, the motor 5 drives the connecting block 6 to rotate along the arc opening 102 through the rotating bar 501, and thereby drives the sliding rod 601 to slide inside the arc opening 102, and thereby touches the touch probe 401 to achieve rapid operation.
