[0021] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0022] Lithium battery aluminum shell is used to protect lithium batteries and is one of the key materials for the production of lithium batteries. The size detection of lithium battery aluminum shell is essential. However, when the image measuring instrument is used to measure the size of lithium battery aluminum shell, due to its light weight, the probe of the image measuring instrument is easy to displace the lithium battery aluminum shell, which leads to measurement failure.

[0023] Based on this, the present application provides a lithium battery aluminum shell fixing tool, which can solve the problem of displacement of the lithium battery aluminum shell during the measurement process.

[0024] Please refer to Figure 1 and Figure 2 As shown, the utility model is a lithium battery aluminum shell fixing tool, including a positioning frame 1 and a clamping assembly 2; the positioning frame 1 has a contour positioning chamber for placing the lithium battery aluminum shell 4, and the clamping assembly 2 includes a fixed block 21 and a movable block 22 surrounding the contour positioning chamber, and the movable block 22 can move toward the fixed block 21. The lithium battery aluminum shell 4 is placed in the contour positioning chamber of the positioning frame 1 for positioning, and the open end of the lithium battery aluminum shell 4 is located above the contour positioning chamber, so that the probe of the image measuring instrument can be inserted into the inner cavity of the lithium battery aluminum shell 4. Then, the movable block 22 pushes the open end of the lithium battery aluminum shell 4, so that the open end of the lithium battery aluminum shell 4 can be clamped between the fixed block 21 and the movable block 22, thereby preventing the lithium battery aluminum shell 4 from being displaced when the probe of the image measuring instrument contacts the lithium battery aluminum shell 4.

[0025] Furthermore, a lithium battery aluminum shell fixing tool further includes a contour support block 3, and the contour support block 3 is used to support at least in the open end of the lithium battery aluminum shell 4. Before the movable block 22 and the fixed block 21 clamp the lithium battery aluminum shell 4, the contour support block 3 is first supported in the inner cavity of the lithium battery aluminum shell 4 to prevent the movable block 22 from overtravel and damaging the lithium battery aluminum shell 4.

[0026] Please refer to Figure 3 As shown, in an optional embodiment, a limiting strip 31 is provided on the top of the profiling support block 3, and the limiting strip 31 is used to abut against the top of the lithium battery aluminum shell 4. Since the movable block 22 and the fixed block 21 are close to the open end of the lithium battery aluminum shell 4, the most economical support method is that the profiling support block 3 is only supported on the open end of the lithium battery aluminum shell 4. Therefore, the limiting strip 31 is provided on the top of the profiling support block 3 to prevent the profiling support block 3 from sinking into the bottom of the inner cavity of the lithium battery aluminum shell 4.

[0027] Please refer to Figure 3 As shown, in an optional embodiment, the side edge profile of the profiling support block 3 is provided with an avoidance notch 32. The profiling support block 3 can not only avoid the probe of the image measuring instrument by providing the avoidance notch 32, but also ensure that the profiling support block 3 has a sufficiently large support area without reducing the thickness of the profiling support block 3.

[0028] Please refer to Figure 3 As shown, in an optional embodiment, a handle 33 is provided on the top of the contoured support block 3. The handle 33 can facilitate the placement of the contoured support block 3 in the inner cavity of the lithium battery aluminum shell 4.

[0029] Please refer to Figure 1 and Figure 2As shown, in an optional embodiment, the clamping assembly 2 further includes a straight-moving cylinder 23, and the movable end of the straight-moving cylinder 23 is connected to the movable block 22. The straight-moving cylinder 23 not only realizes the movement of the movable block 22, but also facilitates the assembly of the straight-moving cylinder 23, which can reduce the difficulty of maintenance.

[0030] Please refer to Figure 1 and Figure 2 As shown, in an optional embodiment, the positioning frame 1 includes a base 11, a connecting rod 12 and a clamping platform 13, a positioning block 111 is arranged on the top surface of the base 11, one end of the connecting rod 12 is connected to the base 11, and the other end of the connecting rod 12 is connected to the clamping platform 13, and a positioning opening 131 is arranged on the clamping platform 13 for the lithium battery aluminum shell 4 to pass through. The connecting rod 12 connects the base 11 and the clamping platform 13 respectively, which can reduce the material used for the positioning frame 1, and can more intuitively observe whether the lithium battery aluminum shell 4 is completely placed in the positioning frame 1.

[0031] Among them, the preferred connecting rod 12 is a rod that can be extended and retracted along its own axial direction, so that the overall tooling can be clamped and positioned according to lithium battery aluminum shells 4 of different sizes and lengths.

The contour support block 3 is used to support the open end of the lithium battery aluminum shell 4. A limit strip 31 is provided on the top of the contour support block 3, and the limit strip 31 is used to abut against the top of the lithium battery aluminum shell 4.
