[0044] The following refers to Figures 1 to 9 Describe the inspection tooling for the compressive strength of the cover plate pole column according to some embodiments of this application.

[0045] See Figures 1 to 9 As shown, the embodiments of this application provide an inspection tooling for the compressive strength of the cover plate pole column, including: a support member 1, a mounting member 2, a pressing member 3, and a sliding member 4; wherein, the mounting member 2 is arranged on the support member 1, and an installation groove 21 is formed on the side of the mounting member 2, and the installation groove 21 is used for installing the battery cover plate 7 to be detected, and preferably, the battery cover plate 7 is adapted to or has a small clearance fit with the installation groove 21;

[0046] The pressing member 3 is detachably installed on the side of the mounting member 2 where the installation groove 21 is formed, and the pressing member 3 is used for pressing on the side of the battery cover plate 7 facing away from the mounting member 2 to fix the battery cover plate 7 in the installation groove 21;

[0047] The sliding member 4 is slidably connected to the pressing member 3 and is used to move towards the pole column 71 of the battery cover plate 7 to apply pressure to the pole column 71. Of course, not limited to this, the sliding member 4 can also be slidably connected to the mounting member 2, and the mounting member 2 plays a role of supporting and guiding the sliding member 4.

[0048] Based on the structure described above, it can be known that when the inspection tool for the compressive strength of the cover pole provided in the present application is used, the battery cover 7 to be tested is first installed in the mounting groove 21 of the mounting member 2, and then the pressing member 3 is installed on the side of the mounting member 2 to fix the battery cover 7, and then the tool is installed as a whole on the testing machine 6, and then the sliding member 4 is pressed down by the pressure head of the testing machine 6 itself or the force-applying member 5 described below, so that the sliding member 4 moves toward the pole 71 below, and until it rests on the pole 71, and pressure is applied to the pole 71, thereby completing the test of the performance test of the pole 71. After the test is completed, the battery cover 7 can also be taken out.

[0049] It can be seen that the present testing tool can be used to effectively position the battery cover 7 and perform a downward pressure test on the pole 71, that is, the present testing tool can be used to test the side pressure resistance strength of the pole 71 of the battery cover 7. The operation is simple and convenient, which saves manpower and improves the testing effect and accuracy. Moreover, the structure is simple, the processing and manufacturing cost is low, and the adaptability is wider. For battery covers 7 of different specifications and sizes, it is only necessary to replace the mounting component 2 with the mounting groove 21 of different specifications, and the remaining components can be used universally, which further reduces the cost.

[0050] In this embodiment, preferably, Figure 2 and Figure 8 As shown, the pressing member 3 includes a first pressing portion 31 and a second pressing portion 32 which are spaced apart, and the first pressing portion 31 and the second pressing portion 32 are respectively detachably connected to the mounting member 2 and are respectively used to be pressed on both sides of the cover portion of the battery cover 7.

[0051] According to the structure described above, the first pressing portion 31 and the second pressing portion 32 can be pressed simultaneously on opposite sides of the cover portion, so that the battery cover 7 is completely fixed and warping can be avoided, which can affect the accuracy of the test.

[0052] In this embodiment, preferably, Figure 2 and Figure 8 As shown, the pressing member 3 also includes a transition portion 33, and the two ends of the transition portion 33 are respectively connected to the first pressing portion 31 and the second pressing portion 32 to form a U-shaped structure, and the opening of the U-shaped structure faces the sliding member 4, which can play a role in avoiding the sliding member 4; the transition portion 33 is used to be pressed on the side of the cover portion of the battery cover 7 away from the mounting member 2, so as to further fix the cover portion below the pole 71.

[0053] According to the structure described above, the first pressing portion 31 and the second pressing portion 32 are connected together by the adapter portion 33, which has a better fixing effect on the cover plate part, facilitates overall assembly, and improves the convenience of operation.

Of course, this is not limited to this. The adapter portion 33 may also have a gap with the supporting member 1. At this time, the supporting member 1 has no supporting effect on the adapter portion 33 and the first pressing portion 31 and the second pressing portion 32 as a whole.

[0056] It should be noted that: the adapter part 33 can also be removed, that is, the pressing component 3 can be composed of only the first pressing part 31 and the second pressing part 32, or the pressing component 3 can include only one pressing part. The specific design is based on actual needs. Especially when the adapter part 33 is removed, preferably, the first pressing part 31 and the second pressing part 32 can be directly pressed against the supporting member 1. Of course, it is not limited to this, and there can also be a gap between the two pressing parts and the supporting member 1.

[0064] Of course, the present invention is not limited to the above structure. Two protrusions may also be provided on the side of the mounting member 2 where the mounting groove 21 is provided. The two protrusions may be located above the mounting groove 21 and spaced apart. The sliding member 4 is provided between the two protrusions and is slidably connected to the two protrusions. That is to say, the sliding member 4 is no longer slidably connected to the pressing member 3, but is slidably connected to the mounting member 2. The specific design is based on actual needs.

[0065] Furthermore, preferably, the sliding member 4 may be a rectangular parallelepiped structure, which is easy to manufacture and facilitates assembly and improves assembly accuracy.

At this time, the bottom of the slider 34 abuts against the side surface of the pole column 71, and both the slider 34 and the pole column 71 are centered with the connecting rod of the working platform 61 to prevent test errors caused by offset.

[0097] Step 7: The second connecting part 52 is inserted into the mounting bushing under the movable crossbeam 62 of the universal mechanical testing machine 6, that is, the second auxiliary connecting part 63, and is limited and fixed by a pin. At this time, the force applying part 51 connected to the second connecting part 52 is placed directly above the sliding member 4.

[0098] Step 8: Start the universal mechanical testing machine 6, and the force is transmitted to the side surface of the pole column 71 through the movable crossbeam 62, the second connecting part 52, the force applying part 51 and the sliding member to conduct the test.

[0099] It should be noted that the above steps can be adjusted according to actual needs and are not limited to this.

[0100] It can be seen that the inspection tooling for assembling and using the compressive strength of the pole column of this cover plate is relatively convenient, time-saving and labor-saving. Moreover, after the test is completed, it can be gradually disassembled, the battery cover plate 7 can be taken out, and a new battery cover plate 7 to be tested can be replaced.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
