[0002] At present, the commonly used shock absorber structures for automobiles include McPherson structure, double wishbone shock absorber structure, torsion beam structure, etc. The double wishbone suspension has a complex structure, occupies a large space, and has relatively high production and maintenance costs, but this type of suspension can improve handling and comfort, absorb more vibrations, and improve the vibration filtering performance of the chassis. Therefore, the outer diameter restrictions of springs at this stage are particularly large when they are designed. Because the springs that appeared in the development process of other projects of customers interfered with surrounding parts due to excessive expansion of the outer diameter. The customer put forward the requirement that the outer diameter expansion of the spring during the overall operation process of the spring needs to be strictly controlled. To avoid interference with the parts around the spring. In order to meet the requirements of customers, it is necessary to make tooling to simulate and measure the actual operation conditions. It can be measured on a force measuring device.

At the same time, during the test, longer springs are prone to bending, resulting in inaccurate spring test results. In view of this, we propose a measuring disk for measuring the maximum outer diameter of a double-fork arm spring. Utility Model Content

The symmetry axis is symmetrically arranged, and the two groups of threaded rods 44 are fixedly connected. At the same time, since the two groups of threaded rods 44 are mirror-imaged, the threads of the two groups of threaded rods 44 are opposite. After the motor 45 drives the two groups of threaded rods 44 to rotate, the two groups of bottom blocks 41 and the arc blocks 42 are separated to both sides, so that adjustment can be made when facing double fork arm springs of different specifications. The upper surface of the base 1 is rotatably connected with the threaded rods 44, and the upper surface of the base 1 is fixedly connected with the motor 45. The threaded rods 44 are fixedly connected to the output shaft of the motor 45, and the upper surface of the base 1 is fixedly connected with a scale plate 5. The outer diameter of the double fork arm spring can be measured by setting the scale plate 5.

[0025] In this embodiment, the motor 45, bottom block 41, arc block 42 and threaded rod 44 can be adjusted according to the maximum outer diameter of the double fork arm spring, and double fork arm springs of different specifications can be measured, which is more convenient when measuring the maximum outer diameter of the double fork arm spring.

[0026] Embodiment 2

[0027] See also Figure 1 - Figure 4 On the basis of the first embodiment, the utility model provides a technical solution: preferably, the upper surface of the arc block 42 is provided with a protection mechanism 6, the protection mechanism 6 includes an arc groove 61, the inner surface of the arc groove 61 is slidably connected with an arc baffle 62, the inner surface of the arc groove 61 is fixedly connected to one end of the spring 63, and the lower surface of the arc baffle 62 is fixedly connected to the other end of the spring 63. Through the cooperation between the arc groove 61 and the arc baffle 62, when the double fork arm spring is measured, it can effectively ensure that the double fork arm spring is blocked, so as to ensure that when the output shaft of the hydraulic equipment 3 moves downward to squeeze the double fork arm spring, the double fork arm spring The spring will not bend, making the double fork arm spring more stable during measurement. A limiting groove 7 is provided on the inner surface of the arc groove 61. A slide plate 8 is slidably connected to the inner surface of the limiting groove 7. The slide plate 8 is fixedly connected to the arc baffle 62. In order to ensure that the arc baffle 62 can slide more stably, the slide plate 8 is limited by the limiting groove 7 so that the slide plate 8 can only slide in the limiting groove 7. Since the slide plate 8 and the arc baffle 62 are fixed, the function of limiting the up and down sliding of the arc baffle 62 is realized. A trapezoidal groove 11 is provided on the front surface of the arc baffle 62. The inner surface of the trapezoidal groove 11 is slidably connected to an elastic shrink plate 12 In order to ensure the stability of the elastic contraction plate 12, a trapezoidal groove 11 is provided on the inner surface of the arc-shaped baffle plate 62. The trapezoidal groove 11 limits the elastic contraction plate 12 so that the elastic contraction plate 12 can only slide in the trapezoidal groove 11, thereby effectively improving the stability of the elastic contraction plate 12. At the same time, the elastic contraction plate 12 can extend the length of the arc-shaped baffle plate 62. When facing double-fork arm springs of different specifications, the outer arc surface of the double-fork arm spring can be completely blocked, effectively ensuring that the double-fork arm spring will not bend in other directions during the measurement process, making the measurement more accurate. The upper surface of the arc block 42 is provided with an active groove 9. The active groove 9 is provided on the upper surface of the arc block 42. The inner surface of the groove 9 is slidably connected with a slider 10. In order to ensure a more stable sliding of the slider 10, the shape of the slider 10 is designed to be arc-shaped. At the same time, the slider 10 is limited by the movable groove 9 so that the slider 10 can only slide in the movable groove 9, thereby effectively improving the stability of the slider 10. The arc baffle 62 is hinged to one end of the bracket 13, and the slider 10 is hinged to the other end of the bracket 13. In order to ensure that the arc baffle 62 is more stable, the elastic shrinkage plate 12 is supported by the bracket 13 and the slider 10 to ensure that the elastic shrinkage plate 12 will not bend after long-term use, thereby improving the service life of the entire equipment.

[0028] In this embodiment, by providing the arc baffle 62, the arc groove 61 and the elastic contraction plate 12, the outer arc surface of the double fork arm spring can be fixed when measuring the maximum outer diameter of the double fork arm spring to prevent the double fork arm spring from bending, thereby making the measurement more accurate.

[0029] Working principle: when measuring the maximum outer diameter of the double fork arm spring, start the motor 45, the motor 45 drives the two sets of threaded rods 44 to rotate, the threads of the two sets of threaded rods 44 are opposite, after the motor 45 drives the two sets of threaded rods 44 to rotate, the two sets of bottom blocks 41 and the arc blocks 42 are separated to both sides, and the double fork arm spring is placed on the upper surface between the two sets of bottom blocks 41, and at the same time, because the arc baffle 62 slides in the arc groove 61, the arc baffle 62 contacts the outer arc surface of the double fork arm spring, and the slide plate 8 limits the arc baffle 62 to limit the double fork arm spring, ensuring that the double fork arm spring will not separate from the bottom block 41, and the upper end of the double fork arm spring The hydraulic device 3 is started by pressing the output shaft of the hydraulic device 3. After the output shaft of the hydraulic device 3 moves downward and contacts the elastic contraction plate 12, the elastic contraction plate 12 will contract into the arc baffle 62. After the elastic contraction plate 12 is completely in contact with the bottom of the inner surface of the arc groove 61, the arc baffle 62 continues to move downward to ensure that the double fork arm spring is fully protected against bending. At the same time, when the slider 10 contracts into the arc baffle 62 due to the elastic contraction plate 12, the bracket 13 will provide a certain support effect on the elastic contraction plate 12 to prevent the elastic contraction plate 12 from being squeezed by the double fork arm spring after long-term use, causing the arc baffle 62 to be deformed.
