Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a multi-purpose cylindrical battery testing fixture. Background Technology

[0002] Against the backdrop of the rapid development of the new energy industry, cylindrical batteries, as key energy storage components in the new energy field, are becoming increasingly important for safety and reliability testing. Among them, the nail penetration test is one of the core methods for evaluating the safety performance of cylindrical batteries. This test needs to simulate the battery's reaction when it is punctured by a sharp object in order to verify whether there are risks such as leakage, fire, or explosion.

[0003] In actual testing, cylindrical batteries need to undergo nail penetration tests in both upright and horizontal positions. Simultaneously, X-ray imaging technology is required to perform puncture tests on any point along the battery cross-section, ensuring comprehensive coverage of areas potentially posing safety hazards. Furthermore, because cylindrical batteries have pressure relief ports at both ends, sufficient space must be provided for these ports during testing to prevent overpressure shocks or even explosions caused by insufficient pressure release, thus ensuring the safety of the test.

[0004] However, current testing fixtures on the market have obvious limitations: on the one hand, different models of cylindrical batteries have different diameters and lengths, and traditional fixtures can often only be adapted to batteries of specific specifications, making it difficult to achieve universal testing of batteries of multiple specifications, resulting in frequent replacement of testing equipment and low efficiency; on the other hand, existing fixtures cannot simultaneously meet the stable fixation requirements in both upright and horizontal positions during clamping, and are prone to obstructing the needle-punch area or pressure relief port of the battery, affecting the accuracy and safety of the test. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-purpose cylindrical battery testing fixture, which solves the problem that traditional battery fixtures can only be adapted to batteries of specific specifications, making it difficult to achieve universal testing of batteries of multiple specifications, and cannot simultaneously meet the stable fixing requirements in both upright and horizontal positions, resulting in frequent replacement of testing equipment and low efficiency.

[0006] To achieve the above objectives, this utility model provides a multi-purpose cylindrical battery testing fixture, including a base, a positioning assembly, and a clamping assembly. The positioning assembly includes a slider, a clamping block, a clamping screw, and a guide rod. Multiple sliders are slidably connected to the base and located inside the base. Multiple clamping blocks are fixedly connected to the sliders and located on top of the sliders. Multiple clamping screws are rotatably connected to the base and pass through the sliders. Two guide rods are slidably connected to the clamping blocks and pass through them. The clamping assembly is connected to the base.

[0007] The base has multiple grooves on its surface, and each groove has a rotating slot inside it.

[0008] The clamping assembly includes a lower plate, support screws, and fixing nuts. The lower plate is detachably connected to the base and is located in the middle of the base. There are multiple support screws, which are fixedly connected to the lower plate and are located on the top of the lower plate. There are multiple fixing nuts, which are threadedly connected to the support screws and are located on the outside of the support screws.

[0009] The clamping assembly further includes a cover plate, which is slidably connected to the support screw and located below the fixing nut.

[0010] The lower plate and the cover plate are respectively provided with a fixing groove on their inner sides, and each fixing groove is provided with a puncture groove inside.

[0011] This utility model relates to a multi-purpose cylindrical battery testing fixture. The base provides support for the device, the slider guides and supports the clamping block, the clamping block clamps the lower plate, and the clamping screw facilitates control of the clamping block. The guide rod guides the clamping block. In use, the cylindrical battery is clamped in the middle of the clamping assembly. The clamping assembly can then be placed vertically or horizontally in the middle of the base as needed. Rotating the clamping screw moves the clamping block along the slider and guide rod, clamping the clamping assembly. This facilitates clamping and fixing of the cylindrical battery, solving the problems of traditional battery fixtures that often only fit specific battery specifications, making it difficult to achieve universal testing of multiple battery specifications, and failing to simultaneously meet the stable fixing requirements in both vertical and horizontal positions, leading to frequent equipment replacements and low efficiency.

Figure 4This is a schematic diagram of the clamping assembly of the first embodiment of this utility model. This utility model provides a multi-purpose cylindrical battery testing fixture, including a base 101, a positioning assembly, and a clamping assembly. The positioning assembly includes a slider 102, a clamping block 103, a clamping screw 104, and a guide rod 105. The clamping assembly includes a lower plate 108, a support screw 109, a fixing nut 110, and a cover plate 111. The aforementioned solution solves the problem that traditional battery clamps can only be adapted to batteries of specific specifications, making it difficult to achieve universal testing of batteries of multiple specifications. It also fails to meet the stable fixing requirements in both upright and horizontal positions, leading to frequent replacement of testing equipment and low efficiency. It is understood that the aforementioned solution can be used in various scenarios and can also be used to solve other problems.

[0020] In this specific embodiment, there are multiple sliders 102, each slidably connected to the base 101 and located inside the base 101. There are multiple clamping blocks 103, each fixedly connected to the slider 102 and located at the top of the slider 102. There are multiple clamping screws 104, each rotatably connected to the base 101 and passing through the slider 102. There are two guide rods 105, each slidably connected to the clamping block 103 and passing through the clamping block 103. The clamping assembly is connected to the base 101. The device is connected in section 01. The base 101 provides support for the device. The slider 102 provides guidance and support for the clamping block 103. The clamping block 103 clamps the lower plate 108. The clamping screw 104 facilitates control of the clamping block 103. The guide rod 105 provides guidance for the clamping block 103. In use, the cylindrical battery is clamped in the middle of the clamping assembly. Then, as needed, the clamping assembly is placed upright or horizontally in the middle of the base 101. Rotating the clamping screw 104 moves the clamping block 103 along the slider 102 and the guide rod 105 to clamp the clamping assembly, facilitating the clamping and fixing of the cylindrical battery.

[0021] The base 101 has a plurality of sliding grooves 106 on its surface. Each sliding groove 106 has a rotating groove 107 inside. The sliding groove 106 cooperates with the slider 102 to provide guidance for the clamping block 103. The rotating groove 107 cooperates with the clamping screw 104 to provide control for the position of the slider 102.

[0022] Secondly, the lower plate 108 is detachably connected to the base 101 and is located in the middle of the base 101. There are multiple supporting screws 109, which are fixedly connected to the lower plate 108 and are located on the top of the lower plate 108. There are multiple fixing nuts 110, which are threadedly connected to the supporting screws 109 and are located on the outside of the supporting screws 109. The lower plate 108 provides support for the cylindrical battery and the supporting screws 109. The supporting screws 109 and the fixing nuts 110 are used to fix the position of the cover plate 111.

[0023] Furthermore, the cover plate 111 is slidably connected to the support screw 109 and is located below the fixing nut 110. The cover plate 111 cooperates with the lower plate 108 to provide a fixing effect for the cylindrical battery.

[0024] Finally, a fixing groove 112 is provided on the inner side of the lower plate 108 and the cover plate 111, and a puncture groove 113 is provided inside each fixing groove 112. The fixing groove 112 is used to initially position the cylindrical battery, and the puncture groove 113 is used to puncture the battery vertically and provide a pressure relief space for the cylindrical battery during puncture.

[0025] Using the multi-purpose cylindrical battery testing fixture of this embodiment, the base 101 provides support for the device, the slider 102 provides guidance and support for the clamping block 103, the clamping block 103 clamps the lower plate 108, the clamping screw 104 facilitates control of the clamping block 103, and the guide rod 105 provides guidance for the clamping block 103. In use, the cylindrical battery is clamped in the middle of the clamping assembly, and then the clamping assembly is placed upright or horizontally in the middle of the base 101 as needed. Rotating the clamping screw 104 drives the clamping block 103 to move along the slider 102 and the guide rod 105 to clamp the clamping assembly, which facilitates clamping and fixing of the cylindrical battery. This solves the problem that traditional battery fixtures can only be adapted to specific battery specifications, making it difficult to achieve universal testing of multiple battery specifications, and cannot simultaneously meet the stable fixing requirements in both upright and horizontal positions, leading to frequent replacement of testing equipment and low efficiency.
