Therefore, its safety and performance are related to whether the "heart" of new energy electric vehicles is reliable, which directly affects whether our travel is safe.

[0003] The burst test and pressure test of the cylindrical battery aluminum shell can ensure the excellent quality of the aluminum shell. During the burst pressure test (also called the gas burst test), high-pressure gas is used to impact the inside of the aluminum shell, so that it is in a pressure environment of 1 to 3.5Mpa. By observing the damage to the battery shell, the strength of the aluminum shell can be evaluated. During the pressure test (also called the gas pressure test), high-pressure gas is used to impact the aluminum shell, so that it is in a pressure environment of 1.2Mpa. With the aluminum shell not bursting as a reference, the expansion of the battery shell is observed to evaluate the pressure resistance of the aluminum shell.

[0023] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0024] Embodiment 1:

[0025] This embodiment introduces the specific structure of a semi-automatic auxiliary tooling for cylindrical aluminum shell blasting inspection equipment. Figure 1-Figure 3As shown, it includes a pressure frame 12, a pressure frame 10 arranged on the top of the pressure frame 12, and two detection heads 6 respectively located at both ends of the pressure frame 10, a battery aluminum shell 11 is adapted and connected between the pressure frame 10 and the pressure frame 12, one side of one detection head 6 is assembled and connected with a second horizontal cylinder 13, one side of the other detection head 6 is provided with a first horizontal cylinder 8, and the top of the pressure frame 10 is assembled and connected with a longitudinal cylinder 4;

[0026] Among them, a main frame 3 is provided at the bottom of the longitudinal cylinder 4, the bottom of the main frame 3 is assembled and connected with an electrical base 2, and the bottom of the electrical base 2 is assembled and connected with a tooling frame 1. By assembling and fixing the bottom of the fixed part of the longitudinal cylinder 4 with the top of the main frame 3, when one end of the movable part of the longitudinal cylinder 4 extends from the inside of the main frame 3, the pressure frame 10 is controlled to move up and down on the top of the pressure frame 12, and the battery aluminum shell 11 on the top of the pressure frame 12 can be clamped;

[0027] At the same time, a stand 14 is processed on the top of one end of the electrical base 2, and a stand plate 9 is processed on the top of the other end of the electrical base 2. One end of the fixed part of the first transverse cylinder 8 is assembled and connected with an assembly bracket 7. By assembling one end of the fixed part of the second transverse cylinder 13 on one side of the stand 14, and one end of the movable part of the second transverse cylinder 13 extends from the inside of the stand 14, a detection head 6 can be controlled by the second transverse cylinder 13. The first transverse cylinder 8 controls another detection head 6 through the assembly bracket 7 to clamp the two ends of the battery aluminum shell 11, and in the process of continuous pressure, the battery aluminum shell 11 is deformed, thereby achieving the effect of pressurizing the gas inside the battery aluminum shell 11;

[0028] Secondly, in order to facilitate the longitudinal cylinder 4 to stably control the pressure frame 10 to move up and down on one side of the main frame 3, as shown in FIG. Figure 1 and Figure 3 As shown, the tops of both ends of the pressure frame 10 are assembled and connected with guide rods 5. By sliding the two guide rods 5 inside the main frame 3, a fixed track can be provided for the pressure frame 10 to move up and down, so that the pressure frame 10 and the pressure frame 12 can cooperate to clamp the battery aluminum shell 11;

[0029] Furthermore, in order to position the pressure frame 12 at the bottom of the pressure frame 10, the pressure frame 10 and the pressure frame 12 are aligned when they cooperate to clamp the battery aluminum shell 11, such as Figure 1 and Figure 3As shown, the same guide rail 15 is provided at the bottom of the pressure frame 12 and the assembly bracket 7. By assembling the guide rail 15 on the top of the electrical base 2 and between the vertical frame 14 and the vertical plate 9, when the first transverse cylinder 8 controls the one side detection head 6 to pressurize one end of the battery aluminum shell 11 through the assembly bracket 7, the pressure frame 12 and the assembly bracket 7 can both slide on the outside of the guide rail 15 to ensure that when the two detection heads 6 clamp the two ends of the battery aluminum shell 11, the pressure frame 10 and the pressure frame 12 clamp the top and bottom of the battery aluminum shell 11 in a facing manner.

[0030] By adopting the above technical solution:

[0031] The above-mentioned design controls the pressure frame 10 by the longitudinal cylinder 4 to approach the pressure frame 12 at the bottom under the guidance of the two guide rods 5 and the main frame 3, thereby clamping the battery aluminum shell 11, and controls a detection head 6 by the second transverse cylinder 13, and controls another detection head 6 by the first transverse cylinder 8 with the aid of the assembly bracket 7 to synchronously clamp the two ends of the battery aluminum shell 11. In the process of the two detection heads 6 approaching each other and continuously applying pressure, the battery aluminum shell 11 can be deformed and the gas inside it can be pressurized, thereby simulating the existing method of filling with high-pressure gas to detect the explosion-proof and pressure-resistant performance of the battery aluminum shell 11. This method has a high degree of airtightness, can ensure the accuracy of the test results, and is convenient for improving the quality control capability of the battery aluminum shell 11, so that the safety of the electric vehicle power system is more guaranteed.

[0032] Embodiment 2:

[0033] Based on Example 1, this example introduces the specific structure of the assembly bracket 7. A transfer rod 17 is provided inside the assembly bracket 7. A rotating cylinder 16 is provided at one end of the transfer rod 17. The rotating cylinder 16 controls the maximum rotation angle of the rotating shaft to be 360 ​​degrees.

[0034] Among them, by assembling and fixing one side of the rotating cylinder 16 inside the assembly bracket 7, one end of the rotating shaft of the rotating cylinder 16 is threadedly connected to the inside of one end of the transfer rod 17, and the other end of the transfer rod 17 is assembled and fixed with a detection head 6.

[0035] By adopting the above technical solution:

[0036] The above-mentioned design assembles an adapter rod 17 on one side of the detection head 6 inside the assembly bracket 7, and sets a rotating cylinder 16 with a rotating shaft threadedly connected to it at one end of the adapter rod 17. When the rotating cylinder 16 is assembled and fixed to the assembly bracket 7, the rotating shaft can be controlled to rotate with the help of the rotating cylinder 16, and the threaded connection between one end of the rotating shaft and one end of the adapter rod 17 can be adjusted, so as to control the sliding of the adapter rod 17 inside the assembly bracket 7, and finally achieve the effect of adjusting the extrusion distance of the detection head 6 at one end of the adapter rod 17 to one end of the battery aluminum shell 11, which is beneficial to adjust the final pressure of the internal gas of the battery aluminum shell 11 after the two ends of the battery aluminum shell 11 are squeezed, so as to achieve the precise control of the pressurized value of the internal gas of the battery aluminum shell 11.

[0037] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
