[0030] Example 1
[0031] Please see Figure 1As shown, this utility model is a gauge for measuring the thickness of a battery casing, including a base 1 and a pressure plate 4 parallel to the top of the base 1. A support assembly 2 is detachably connected to the rear edge of the base 1. The pressure plate 4 is connected to the support assembly 2 via a sliding mechanism 3. A dial indicator 5 is installed on the top of the support assembly 2, and the dial indicator 5 is connected to the pressure plate 4 via a measuring rod 6. When the battery casing to be measured is placed between the base 1 and the pressure plate 4, the sliding mechanism 3 drives the pressure plate 4 to move down along the support assembly 2. The pressure plate 4 drives the measuring rod 6 to move down and press against the battery casing to be measured, so that the dial indicator 5 can read the thickness data of the battery casing to be measured.
[0032] By assembling the designed base 1, support component 2, sliding mechanism 3, pressure plate 4, and dial indicator 5 into a pump inspection tool, during use, the battery casing to be tested is placed on the worktable of the base 1. The operator can manually move the pressure plate 4 down until it is in tight contact with the battery casing. At this time, the measuring rod 6 slides vertically along with the pressure plate 4. According to the working principle of the dial indicator 5, the magnitude of the linear movement of the measuring rod 6 is amplified through gear transmission, which is transformed into the change of the dial indicator 5 on its scale, so that the value displayed by the digital dial indicator can be read and the battery thickness recorded.
[0033] The fixture in this application has a simple structure and low cost. By adopting manual sliding adjustment and modular design of the fixture, the complex motor drive system can be eliminated, thereby reducing manufacturing costs.
[0034] Example 2
[0035] See Figure 2 As shown, the sliding mechanism 3 includes a stabilizing slider 30, a docking block 31, and a sliding guide rail 32. The stabilizing slider 30 and the docking block 31 are detachably connected, and a sliding guide rail 32 is provided between the stabilizing slider 30 and the docking block 31. The docking block 31 is used to detachably connect to the pressure plate 4, and the sliding guide rail 32 is used to guide the sliding connection to the fixed guide rail seat 23. The front surface of the docking block 31 is connected to the pressure plate 4 through a reinforcing block 33. The sliding guide rail 32 is symmetrically arranged on both sides of the stabilizing slider 30. The fixed guide rail seat 23 is vertically and detachably connected to the step surface of the limiting block 22 included in the support assembly 2. The side wall of the stabilizing slider 30 is slidably abutting against the side wall of the step surface of the limiting block 22.
[0036] During use, the sliding mechanism 3 of this application is vertically connected to the docking block 31 and the pressure plate 4, and can be reinforced by the reinforcing block 33 to ensure the stability of the pressure plate 4 structure and avoid affecting the measurement accuracy; so that the pressure plate 4, the stabilizing slider 30, the docking block 31 and the sliding guide rail 32 can slide up and down along the support component 2 as a whole, so that the pressure plate 4 can be manually slid to press tightly against the battery shell to be measured, so that the dial gauge 5 can read the thickness data of the battery shell to be measured.
[0037] Example 3
[0038] See Figure 3 and Figure 4 As shown, the limiting block 22 is detachably connected to the vertical support 20, the vertical support 20 is detachably connected to the base 1, and the tops of the vertical support 20 and the limiting block 22 are detachably connected to the horizontal support 21. A dial indicator 5 is installed on the horizontal support 21.
[0039] The support component 2 of this application is easy to assemble. During the measurement of the battery casing under test, the battery casing under test can be limited and abutted against the limiting block 22 to avoid measurement deviation. Furthermore, the interchangeable fixed guide rail 23 and the limiting block 22 can be used to quickly adapt to batteries of different specifications, thereby improving the flexibility of testing.
[0040] Example 4

The bottom end of the measuring rod 6 is detachably connected to the pressure plate 4 through the positioning plate 7. The top end is provided with a scale knob 8, which is threadedly connected to the dial indicator 5. When the pressure plate 4 presses against the battery casing to be tested, the measuring rod 6 is slightly adjusted downward by pressing the scale knob 8 to adjust the height of the pressure plate 4 pressing against the battery casing. The probe end face of the measuring rod 6 is flush with the lower surface of the pressure plate 4.
[0042] During the use of the dial gauge 5 of this application, the measuring rod 6 can be easily connected to the pressure plate 4 through the positioning plate 7. When the measuring rod 6 moves down with the pressure plate 4 to make tight contact with the battery casing to be measured, the pressure plate 4 can be finely adjusted by rotating the scale knob rod 8 to ensure uniform clamping force, thereby helping to improve measurement accuracy.
[0043] Example 5
[0044] A 2mm thick silicone pad is provided on the lower surface of the pressure plate 4. The silicone pad at the bottom of the pressure plate 4 effectively buffers the pressure and avoids damage to the surface of the battery casing to be tested during the measurement process.
[0045] Example 6
[0046] The base 1 is made of aluminum alloy plate, and there are equal-height support legs 9 at the four corners of the lower surface of the base 1; so as to facilitate the frosting and anti-slip treatment on the worktable of the base 1 and avoid the battery shell under test from being pressed and shifted.
