DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] Example 1

[0034] Tooling for rapid detection of parallelism and flatness of liquid metal cell components, such as Figure 1 , Figure 2As shown, it includes a bracket 1, a detection plate 2, a standard gauge block 3 and a dial indicator assembly 4. The detection plate 2 is fixedly connected to the bracket 1. A circular limit groove 5 is provided on the detection plate 2. A through hole 6 is provided in the center of the limit groove 5. A sleeve 7 is fixedly connected below the through hole 6. The difference between the inner diameter of the sleeve 7 and the maximum diameter of the pole 103 is not greater than ±0.5mm. The upper cover plate 102 of the liquid metal battery component 10 is placed in the limit groove 5, and the pole 103 is inserted in the sleeve 7. The verticality of the pole 103 and the upper cover plate 102 is detected through the sleeve 7. The material of the detection plate 2, the standard gauge block 3 and the sleeve 7 are all POM. The friction coefficient of POM (Saigang) is small, which is conducive to the rotation of the components.

[0035] like Figure 1 , Figure 2 As shown, two standard gauge blocks 3 are slidably connected to the detection plate 2, and the standard gauge block 3 includes a slider 31, a support column 32 and a measuring block 33. The slider 31 is slidably connected to the detection plate 2 along the diameter direction of the limit groove 5, the support column 32 is fixedly connected above the slider 31, and the measuring block 33 is fixedly connected to the side plate of the support column 32. The measuring block 33 is provided with a measuring groove 34 for embedding the porous sheet 101 toward the center direction of the limit groove 5.

[0036] like Figure 1 , Figure 2 As shown, two limiters 8 are fixedly connected to the detection plate 2. The limiters 8 are made of POM. The limiters 8 are located outside the limit slots 5. The limiters 8 are inverted U-shaped. The limiters 8 are used to limit the freedom of the slider 31 in the vertical direction. The gap between the limiters 8 and the detection plate 2 forms a slide groove 9. The slider 31 is slidably connected to the slide groove 9 in the horizontal direction. The setting of the limiters 8 is conducive to the movement of the standard gauge block 3 along the diameter direction of the limit slot 5. At the same time, the slide groove 9 can limit the freedom of the slider 31 in the vertical direction, so that the slider 31 presses the upper cover plate 102, so as to achieve the purpose of limiting the freedom of the parts in the vertical direction, and facilitate the detection of the parts. The inverted U-shaped limiter 8 limits the upward displacement of the slider 31, and the upper cover plate 102 limits the downward displacement of the slider 31. When the flatness of the upper cover plate 102 does not meet the standard, since the slider 31 is connected to the upper surface of the upper cover plate 102, the flatness of the upper cover plate 102 will affect the position of the slider 31 along the vertical direction, thereby changing the value of the dial indicator 41. Based on this principle, the flatness of the upper cover plate 102 can be detected by the dial indicator 41.

[0037] Before placing the component in the limiting groove 5, slide the standard gauge block 3 to make the measuring groove 34 away from the limiting groove 5. After placing the component in the limiting groove 5, push the standard gauge block 3 to make the measuring groove 34 of the standard gauge block 3 connect with the porous sheet 101 of the component.

[0038] like Figure 1 , Figure 2 As shown, the dial indicator assembly 4 includes a dial indicator 41 and a supporting structure 42, the supporting structure 42 includes a column 421 and a beam 422, the column 421 is fixedly connected to the detection plate in the vertical direction, the beam 422 is fixedly connected above the column 421 in the horizontal direction, the dial indicator 41 is fixedly connected to the beam 422, the measuring head of the dial indicator 41 is in contact with the upper surface of the porous sheet 101, and the parts are rotated to detect the distance between the upper cover plate 102 and the porous sheet 101, and the parallelism and flatness of the upper cover plate 102 and the porous sheet 101 through the standard gauge block 3.

[0039] Example 2

[0040] The difference between the distance between the bottom surface of the slider 31 and the bottom surface of the limit groove 5 and the thickness of the upper cover plate 102 is not greater than ±0.5mm. When the measuring groove 34 contacts the porous sheet 101, the bottom surface of the slider 31 contacts the upper cover plate 102. Slide the standard gauge block 3 so that the standard gauge block 3 is located above the upper cover plate 102, and rotate the upper cover plate 102. If the bottom surface of the standard gauge block 3 is always in contact with the upper cover plate 102, and the value change of the dial indicator 41 is within the set range, it means that the thickness of the upper cover plate 102 meets the detection standard.

[0041] Example 3

[0042] The difference between the height of the measuring groove 34 and the thickness of the porous sheet 101 is no more than ±0.5 mm, the bottom surface of the porous sheet 101 is in contact with the bottom surface of the measuring groove 34, the porous sheet 101 can rotate in the measuring groove 34, and the value change of the dial indicator 41 is within the set range, which means that the flatness and thickness of the porous sheet 101 meet the detection standards.

[0043] Example 4

[0044] The difference between the spacing between the bottom surface of the measuring groove 34 and the upper surface of the limiting groove 5 and the bottom surface of the upper cover plate 102 and the bottom surface of the porous sheet 101 is not greater than ±0.5mm. The upper cover plate 102 and the porous sheet 101 can rotate freely in the limiting groove 5 and the measuring groove 34 respectively, and the value change of the dial indicator 41 is within the set range, which means that the spacing and parallelism between the upper cover plate 102 and the porous sheet 101 meet the detection standards.

[0045] Example 5

[0046] The tooling for quickly detecting the parallelism and flatness of liquid metal battery components also includes a PC end, and a dial indicator 41 is electrically connected to the PC end. The detection value of the dial indicator 41 is stored in the PC end for easy retrieval and analysis.
