DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In this embodiment, asFigures 1 - 5 As shown, a high-precision parallel spring plate measuring mechanism includes symmetrically arranged first pressing block 1 and second pressing block 2. The specifications and dimensions of the first pressing block 1 and the second pressing block 2 are adapted to each other, facilitating the restriction of the position of the spring plate 3. A spring plate 3 is arranged between the first pressing block 1 and the second pressing block 2. The spring plate 3 has a relatively large tensile stiffness in the vertical direction, facilitating it to be a sensitive element in the detection structure, and having good mechanical properties, anti-elastic reduction properties, fatigue properties, etc. An active block 4 is arranged above the first pressing block 1, and a fixed block 5 is arranged below the first pressing block 1. The fixed block 5 is in a fixed state without movement. By installing the active block 4 together with the part to be detected, and then through the stretching action of the spring plate, the length value of the part to be detected is accurately displayed on the dial indicator on one side of the fixed block 5.

[0024] As shown in Figure 2 and Figure 3 shown, the spring plate 3 is symmetrically arranged at both ends of the active block 4 and the fixed block 5, playing a restricting role to prevent the spring plate 3 from having tensile changes in the horizontal direction. The upper end of the spring plate 3 is fixedly connected to the active block 4 through a plurality of first screws 6, and the lower end of the spring plate 3 is fixedly connected to the fixed block 5 through a plurality of second screws 7. The number, specifications, and dimensions of the first screws 6 and the second screws 7 are all adapted to each other, reducing the influence on the spring plate 3 caused by the differences between the first screws 6 and the second screws 7 and avoiding reducing the accuracy.

[0025] As shown in Figure 2 and Figure 5 shown, the active block 4 includes an actively connected active horizontal plate 41 and active vertical plate 42. The active horizontal plate 41 and the active vertical plate 42 are set as an integrated T-shaped structure. The active vertical plate 42 is close to the position of the second pressing block 2 on the left side, enabling the active vertical plate 42 to be slidably connected to a special fixture and installing the active block 4 on the special fixture.

[0026] As shown in Figure 2 and Figure 5 shown, the fixed block 5 includes a fixedly connected fixed horizontal plate 51 and fixed vertical plate 52. The fixed horizontal plate 51 and the fixed vertical plate 52 are set as an integrated T-shaped structure. The fixed vertical plate 52 is close to the position of the second pressing block 2 on the right side. The specifications and dimensions of the fixed vertical plate 52 are larger than those of the active vertical plate 42. A chamfer is arranged at the top of the fixed vertical plate 52, and the chamfer is arranged on the side of the fixed vertical plate 52 close to the second pressing block 2, enabling the fixed vertical plate 52 to be fixedly connected to a special fixture and fixedly installing the fixed block 5 on the special fixture.

[0027] As shown in Figure 1As shown, a non-standard probe is installed on one side of the movable block 4, and a dial indicator is installed on one side of the fixed block 5, which can also be set as a linear sensor, facilitating the accurate display of values and having good detection accuracy.

[0028] As shown in Figure 2 and Figure 3 As shown, notches are provided on one side of the movable block 4 and the fixed block 5 close to the second pressing block 2 to prevent interference with the second pressing block 2 when the spring piece 3 resets, avoid damaging the mechanism, and thus extend the service life.

[0029] As shown in Figure 2 As shown, a plurality of screw holes are provided on the side of the first pressing block 1 away from the second pressing block 2, and bolts are threadedly arranged inside the screw holes. One end of the bolts penetrates through the spring piece 3 and extends into the second pressing block 2, facilitating the limitation of the position of the spring piece 3 and thus increasing the overall practicality.

[0030] As shown in Figure 1 As shown, the second pressing block 2 is arranged on the side of the spring piece 3 close to the movable block 4 to prevent interference with the mechanism and cause the mechanism to malfunction.

[0031] Working principle: Install a dial indicator or a linear sensor on the fixed block 5, install a non-standard probe on the movable block 4, and then install the whole on a special fixture. The fixed block 5 is fixedly connected to the special fixture, and the movable block 4 is slidably connected to the special fixture. By installing a spring piece 3 on each side, the movable block 4 can achieve parallel movement relative to the fixed block 5, enabling the length measurement of different structural parts. The spring piece enables the movable block 4 to display the corresponding acting force in the form of accurate values through the dial indicator or the linear sensor.

[0032] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
