Description

Technical Field

[0001] This utility model relates to the field of battery terminal calibration technology, specifically a tooling for calibrating the height of battery terminals. Background Technology

[0002] In the battery manufacturing process, the terminals serve as the connection interface between the battery and the external circuit and the module. Their height consistency directly determines the quality of subsequent module assembly. If the terminal height deviation exceeds 0.1mm, it will cause the connection between adjacent battery terminals in the module to become loose and the contact resistance to increase, which in turn will cause local overheating and even induce the risk of fire (especially for power battery modules).

[0003] A search revealed a patent, CN218939776U, which discloses a battery terminal calibration tool. The tool includes a positioning seat, a positioning cavity, and a guide hole. The bottom diameter of the positioning seat is the same as the inner diameter of the battery casing terminal hole. The bottom end face of the positioning seat has a positioning cavity that can be movably fitted with the corresponding battery terminal. A guide hole, vertically penetrating the positioning seat, is located at the center of the top of the positioning cavity. A pull rod, which can be threaded into the guide hole and corresponds to the threaded hole of the battery terminal, is movably inserted into the guide hole. An annular boss is located on the top of the pull rod corresponding to the top of the positioning seat. The positioning seat body has a limiting ring platform with a diameter larger than the inner diameter of the battery casing terminal hole. This utility model has a simple structure, is easy to use, and can calibrate the coaxiality of the battery terminal and the battery casing terminal hole, as well as the extension length of the battery terminal, in one operation. It has high calibration accuracy, high work efficiency, and greatly improves production efficiency.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In the aforementioned comparative documents, a positioning seat is inserted into the terminal hole, and the height of the terminal is adjusted and calibrated by a pull rod. However, in reality, it is difficult to manually adjust the height of the connected terminal by the pull rod, which reduces the efficiency of calibrating the height of the battery terminal. Therefore, there is an urgent need in the art to improve the tooling used for calibrating the height of the battery terminal to overcome the shortcomings of the prior art. Utility Model Content

A first positioning ring 6 is provided at the lower end of the connecting frame 5, and a second positioning ring 7 adapted to the mounting holes is provided at the lower part of the first positioning ring 6. The inner cavity of the second positioning ring 7 and the first positioning ring 6 is adapted to the diameter of the terminal posts 2. An elastic rubber pad 8 is fitted on the side of the second positioning ring 7. A connecting bolt 9 is threaded through and threaded onto the connecting frame 5, one end of which is threaded to the threaded hole 10 at the upper end of the terminal post 2. A clamping unit for clamping the battery body 1 is provided on the side of the clamping frame 3, and an adjustment unit for adjusting the first sliding block 4 is provided at the upper part of the clamping frame 3. The clamping unit includes a fixed clamping plate 11 fixedly installed on the lower side of the clamping frame 3. The side of the frame 3 is provided with a movable clamping plate 12 that is adapted to the fixed clamping plate 11. The side of the clamping frame 3 is provided with a second sliding groove 14. The side of the movable clamping plate 12 is fixedly installed with a second sliding block 13 that is adapted to the second sliding groove 14. The side of the clamping frame 3 is provided with a through opening 24. A second adjusting threaded rod 15 is provided in the through opening 24, one end of which extends into the second sliding groove 14. The second adjusting threaded rod 15 is threadedly connected to the second sliding block 13. The side of the second adjusting threaded rod 15 located in the through opening 24 is threadedly connected with a second limiting nut 16. The adjusting unit includes a first adjusting threaded rod 22 provided on the upper part of the clamping frame 3. The side of the upper part of the clamping frame 3 is provided with a first sliding groove 21 that is adapted to the first sliding block 4. One end of the first adjusting threaded rod 22 extends into the first sliding groove 21 and is threadedly connected to the first sliding block 4. The side of the upper end of the first adjusting threaded rod 22 is threadedly connected with a first limiting nut 23.

[0031] In this embodiment, the specific implementation is as follows: When the height of the terminal post 2 on the battery body 1 needs to be adjusted, the battery body 1 is placed on an operating table smaller than the lower part of the battery body 1. The clamping frame 3 is snapped onto the side of the battery body 1. The fixed clamping plate 11 is located at the lower part of the battery body 1, and the movable clamping plate 12 is located at the upper part of the battery body 1. The position of the second positioning ring 7 is aligned with the position of the mounting hole on the battery body 1. The second adjusting threaded rod 15 is rotated. When the second adjusting threaded rod 15 rotates, it drives the second sliding block 13 to slide in the second sliding groove 14. The second sliding block 13 drives the movable clamping plate 12 to move. The movable clamping plate 12 and the fixed clamping plate 11 are clamped on the side of the battery body 1. The second limiting nut 16 is locked to limit and fix the position of the movable clamping plate 12. This allows the installation of battery bodies 1 of different heights. By rotating the first adjusting threaded rod 22, the first adjusting threaded rod 22 drives the first sliding... Block 4 moves within the first sliding groove 21, causing the connecting frame 5 to move. The connecting frame 5 then causes the first positioning ring 6 to move. The second positioning ring 7 is inserted into the mounting hole on the upper part of the battery body 1. The terminal post 2 passes through the first positioning ring 6 and the second positioning ring 7, and the rubber pad 8 contacts the upper part of the battery body 1. The elastic rubber pad 8 prevents scratches on the battery body 1. The connecting bolt 9 is rotated, and one end of the connecting bolt 9 is threadedly connected to the threaded hole 10 on the upper part of the battery body 1. Then, by rotating the first adjusting threaded rod 22 again, the connecting frame 5 is adjusted up and down. There is no need to manually adjust the height of the terminal post 2, which facilitates the height calibration of the terminal post 2 and improves the efficiency of calibrating the battery terminals. Furthermore, by using the first positioning ring 6 and the second positioning ring 7, which are adapted to the mounting hole on the terminal post 2 and the battery body 1, the vertical center position of the terminal post 2 is not affected when adjusting its height.

[0032] Example 2
