Description

Technical Field

[0001] This utility model relates to the field of battery clamping technology, and in particular to an auxiliary clamping fixture for lithium battery processing. Background Technology

[0002] Lithium batteries are a general term for a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. They are rechargeable batteries whose core working principle relies on the movement of lithium ions between the positive and negative electrodes to store and release energy.

[0003] However, in existing technologies, existing lithium batteries are typically clamped and fixed during processing to maintain their stability. Since lithium battery modules are composed of multiple cells connected in series or parallel, it is necessary to ensure that the positive and negative poles of all cells are aligned. During processing, a 90-degree rotation can automatically correct the cell orientation. However, most existing lithium batteries, after being clamped and fixed by clamping fixtures, require the clamping and fixing of the battery to be released before a 90-degree rotation adjustment is needed. The battery must then be manually rotated and clamped again. This rotation adjustment method is cumbersome, inconvenient, and wastes processing time. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: when most lithium batteries are clamped and fixed by a clamping fixture, and need to be rotated 90 degrees for adjustment, it is necessary to first release the clamping fixture, then manually rotate the lithium battery, and then continue to clamp and fix the rotated lithium battery. This rotation adjustment method is cumbersome, not easy to operate, and easily wastes processing time for lithium batteries.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary clamping fixture for lithium battery processing, comprising a base, wherein upright plates are fixedly connected to the left and right ends of the upper surface of the base, and a placement frame is provided between the upright plates. A first rotating shaft and a second rotating shaft are fixedly connected to the two sides of the placement frame, and both the first and second rotating shafts are rotatably connected to the upright plates. A lead screw is threaded through one side of the placement frame and the center of the first rotating shaft, and one end of the lead screw is rotatably connected to a pressing plate. A positioning hole is provided on the outer surface of the second rotating shaft, and four positioning holes are equidistantly arranged around the center of the second rotating shaft. An insert is engaged in the positioning hole, and the insert is connected to the upright plate. A fixing ring is fixed to the outer surface of the insert and a spring is sleeved thereon.

[0006] In a preferred embodiment, a supporting triangular plate is fixedly connected to the mating surface of the base and the upright plate.

[0007] In a preferred embodiment, a protective cover is fixedly connected to one side of each of the two upright plates near the installation positions of the first and second rotating shafts, and the protective cover is rotatably embedded in one end of the first and second rotating shafts, and the protective cover is connected through the lead screw.

[0008] In a preferred embodiment, a torsion bar is fixedly connected to one end of the lead screw.

[0009] In a preferred embodiment, one end of the plug is threaded with a bolt, and a tension ring is slidably connected to the surface of the bolt. A nut is threaded to the side of the tension ring on the surface of the bolt.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This invention involves placing a lithium battery in a placement frame, then using a rotating screw to horizontally push the compression plate within the frame, clamping and securing the battery. When the battery needs to be rotated 90 degrees, the insert is pulled outwards to disengage from the positioning hole, releasing the frame from its lock. With the assistance of the first and second rotating shafts, the frame rotates between the uprights. Once the next positioning hole aligns with one end of the insert, it indicates that the frame and the clamped battery have completed a 90-degree rotation. At this point, the insert connects to the next positioning hole, relocking the frame and ensuring its stability after rotation. This method simplifies the battery rotation process and saves time.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] like Figure 1-4As shown, this utility model provides a technical solution: an auxiliary clamping fixture for lithium battery processing, including a base 1. Vertical plates 2 are fixedly connected to the left and right ends of the upper surface of the base 1. The vertical plates 2 provide overall support for the placement frame 4, the first rotating shaft 5, and the second rotating shaft 10. A placement frame 4 is positioned between the vertical plates 2. The lithium battery is placed on the plane of the placement frame 4. The first rotating shaft 5 and the second rotating shaft 10 are fixedly connected to both sides of the placement frame 4, and both the first rotating shaft 5 and the second rotating shaft 10 are... The upright plate 2 is rotatably connected. With the help of the first rotating shaft 5 and the second rotating shaft 10, the entire placement frame 4 can rotate between the upright plate 2. A lead screw 7 is threaded through one side of the placement frame 4 and the center of the first rotating shaft 5, and one end of the lead screw 7 is rotatably connected to a pressing plate 8. After the lithium battery is placed in the placement frame 4, the pressing plate 8 in the placement frame 4 is pushed horizontally by rotating the lead screw 7, so that the pressing plate 8 clamps and fixes the lithium battery placed in the placement frame 4. The outer surface of the second rotating shaft 10... Positioning holes 11 are provided on the surface. Four positioning holes 11 are equidistantly arranged around the center of the second rotating shaft 10, and plugs 12 are engaged in the positioning holes 11. The plugs 12 are connected to the upright plate 2 through the holes. When the lithium battery needs to be rotated 90 degrees, the plugs 12 are pulled outward to disengage from the positioning holes 11, thereby releasing the placement frame 4 from its lock. The placement frame 4 can then rotate between the upright plates 2. When the next positioning hole 11 is observed to align with one end of the plug 12, it indicates that the placement frame 4 is clamped on it. The fixed lithium battery has completed a 90-degree rotation. At this time, the plug 12 is connected to the next positioning hole 11, and the placement frame 4 is relocked to ensure its stability after rotation. The operation is simple and convenient. The outer surface of the plug 12 is fixed with a fixing ring 13 and a spring 14. When the plug 12 is inserted into the positioning hole 11, the spring 14 located between the upright plate 2 and the fixing ring 13 will resist the outward movement of the plug 12 and the fixing ring 13 due to its own elasticity, thus improving the stability of the connection between the plug 12 and the positioning hole 11.

[0021] Example 2

[0022] like Figure 1-4As shown, a supporting triangular plate 3 is fixedly connected to the mating surface of the base 1 and the upright plate 2. The supporting triangular plate 3 provides support for one side of the upright plate 2, improving the stability of the upright plate 2 when it is vertically fixed on the base 1. Protective covers 6 are fixedly connected to one side of both upright plates 2 near the installation positions of the first rotating shaft 5 and the second rotating shaft 10. The protective covers 6 are rotatably embedded in one end of the first rotating shaft 5 and the second rotating shaft 10. The protective covers 6 are connected through the lead screw 7. The protective covers 6 protect the outer ends of the first rotating shaft 5 and the second rotating shaft 10, reducing wear. The lead screw 7... One end is fixedly connected to a torsion bar 9, which allows for easy manual control of the screw 7 to rotate. One end of the plug 12 is threadedly connected to a bolt 15, and a pull ring 16 is slidably connected to the surface of the bolt 15. A nut 17 is threadedly connected to the surface of the bolt 15 on one side of the pull ring 16. By installing the nut 17 on the bolt 15, the pull ring 16 on the bolt 15 is compressed, improving the stability of the pull ring 16 on the bolt 15. Installing the bolt 15 with the pull ring 16 on one end of the plug 12 makes it easier for a person to move the plug 12 outward by pulling the pull ring 16.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
