Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery terminal welding technology, specifically to a tooling for rapid welding of power battery terminals. Background Technology
[0002] Battery terminals are electrical contacts used to connect a load or charger to a single or multiple batteries. They are typically connected to the battery by soldering.
[0003] Existing equipment for welding lead-acid batteries typically involves using a single shield to cover the terminal, thus isolating it and allowing for safe welding of the battery terminals. However, this process requires removing the shield and installing it on another terminal each time, which is cumbersome and can easily delay overall operational efficiency.
[0004] To address the aforementioned technical problems, patent document CN219725107U discloses a quick-welding terminal fixture for lead-acid batteries, comprising: a connecting plate and two movable plates, a first movable plate and a second movable plate, detachably disposed on both sides of the connecting plate. A partition is fixed to the upper surface of the first movable plate and the second movable plate, the partition being positioned between the lead-acid battery terminal and the electrode post. An embedding portion is provided on the lower surface of the first movable plate and the second movable plate, the embedding portion being embedded into the edge of the electrode post groove to position the first movable plate and the second movable plate. By separating the positions of the two electrodes with partitions on both sides, the electrodes and corresponding terminals are prevented from contacting each other, allowing for simultaneous fixing of two terminals in a single installation, thus improving efficiency. An adjustment groove is formed on the upper surface of one end of the connecting plate, and a positioning hole is formed on the upper surface of the other end of the connecting plate. Movable plate one and movable plate two are arranged perpendicularly to the connecting plate. Several rows of positioning holes two, corresponding to the positions of positioning holes one, are formed on the surfaces of movable plate one and movable plate two. The positioning holes two of movable plate one are fixed to positioning holes one by bolts, and the positioning holes two of movable plate two are fixed to the adjustment groove by bolts. When the bolts are loosened, movable plate two can move linearly along the adjustment groove. That is, movable plate one and movable plate two are adjustable, allowing for positional adjustments according to the specifications of different lead-acid batteries, thus meeting the application requirements of lead-acid batteries of different specifications.
[0005] This quick-welding fixture for lead-acid batteries is inconvenient to adjust the positions of movable plates one and two, making adjustment cumbersome. Furthermore, while the partition effectively isolates the terminals from the electrode posts, the posts remain exposed, allowing weld slag to easily splatter onto them during welding. The partition also blocks one side of the terminal, preventing multi-angle operation of the welding torch and making it unsuitable for complex welding paths. Utility Model Content
[0006] The main purpose of this utility model is to provide a fast welding terminal tooling for power batteries that can prevent welding slag from splashing onto the terminal post during the welding process and facilitates adjustment of the positioning position.
[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0008] A tooling for rapid welding of power battery terminals includes a center plate, which is connected to two movable plates via an adjustment assembly. The adjustment assembly can adjust the distance between the two movable plates, which are located below the center plate. The tooling is characterized in that the two movable plates are staggered, and the movable plates have grooves that allow battery terminals to pass through. An elongated groove is formed on one side of the groove on the movable plate, and a protective cover is slidably engaged in the elongated groove. The sliding direction of the protective cover in the elongated groove is perpendicular to the movement direction of the movable plate, allowing the battery terminal to be inserted into the protective cover. The upper end of the protective cover is sealed.
[0009] Specifically, the adjustment assembly includes a groove formed at the lower end of the center plate, the length direction of the groove being parallel to the length direction of the center plate, a slider fixed at the upper end of the movable plate, the slider slidingly engaging in the groove, a double-ended screw rotatably connected inside the groove, one end of the double-ended screw extending to the outside of the center plate, the double-ended screw passing through the two sliders, and the threaded portions on both sides of the double-ended screw being threadedly connected to the two sliders respectively.
[0010] Specifically, the groove is a dovetail groove, and the slider is a dovetail block.
[0011] Specifically, the protective cover extends through the elongated groove, and an annular groove is provided on the outer edge of the protective cover. The movable plate portion on the outer side of the elongated groove is engaged in the annular groove.
[0012] Specifically, a collar is fixedly sleeved on the outer side of the protective cover above the movable plate, and a screw is threaded onto the collar, with the lower end of the screw tightly abutting the upper end of the movable plate.
[0013] Specifically, the protective cover is cylindrical.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. Through the coordinated design of the double-ended screw, slide groove, and slider, the distance between the two movable plates can be adjusted simultaneously simply by rotating the double-ended screw, achieving rapid adjustment in the length direction of the center plate; the sliding engagement structure between the elongated groove and the protective cover further allows for independent adjustment of the protective cover in the width direction. The bidirectional adjustment mechanism simplifies the operation steps and significantly improves the adaptability efficiency to different battery specifications.
[0016] 2. The cylindrical protective cover completely encloses the battery terminals, and the upper sealing structure forms a physical barrier, completely isolating welding spatter and preventing contamination or damage to the battery terminals. The tight fit between the protective cover and the battery terminals also serves a positioning function, completing protection and positioning in one step.
[0017] 3. The structure of the dovetail groove and the slider enhances the anti-displacement ability of the movable plate during sliding; the snap-fit design of the guard ring groove and the movable plate, together with the screw, not only ensures the flexible sliding of the guard, but also allows for quick fixation after adjustment, ensuring the overall stability of the tooling during welding and avoiding displacement caused by vibration.
[0018] 4. The staggered layout and groove design of the movable plate fully expose the welding area of the battery terminals, allowing the welding gun to be operated at multiple angles; the protective cover only covers the key parts of the battery terminals, achieving a balance between protection and ease of operation, and is especially suitable for complex welding path requirements.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1: Refer to Figures 1-3 As shown, a quick welding terminal tooling for power batteries includes a center plate 1. The center plate 1 is connected to two movable plates 4 via an adjustment assembly. The adjustment assembly can adjust the distance between the two movable plates 4, and the movable plates 4 are located below the center plate 1.
[0025] The adjustment assembly includes a groove 2 formed at the lower end of the center plate 1, the length of which is parallel to the length of the center plate 1. A slider is fixed to the upper end of the movable plate 4, and the slider is slidably engaged in the groove 2. Specifically, the groove 2 is a dovetail groove, and the slider is a dovetail block. A double-ended screw 3 is rotatably connected inside the groove 2. One end of the double-ended screw 3 extends to the outside of the center plate 1, and the double-ended screw 3 passes through the two sliders. The threaded portions on both sides of the double-ended screw 3 are threadedly connected to the two sliders respectively. By rotating the double-ended screw 3, the two movable plates 4 can move away from or closer to each other.
[0026] The two movable boards are set in a 4-position offset.
[0027] The movable plate 4 has a groove 5 that allows the battery terminals to pass through.
[0028] An elongated groove 6 is formed on the movable plate 4 on one side of the groove 5. A protective cover 7 is slidably engaged in the elongated groove 6. The sliding direction of the protective cover 7 in the elongated groove 6 is perpendicular to the movement direction of the movable plate 4. Specifically, the protective cover 7 passes through the elongated groove 6, and an annular groove 10 is formed on the outer edge of the protective cover 7. The movable plate 4 on the outer side of the elongated groove 6 is partially engaged in the annular groove 10.
[0029] The shield 7 is cylindrical, and the battery terminals are allowed to be inserted into the shield 7. The top of the shield 7 is sealed.
[0030] Rotate the double-ended screw 3 to change the distance between the two movable plates 4 along the length of the center plate 1, thereby adjusting the distance between the two grooves 5 and the two protective covers 7 along the length of the center plate 1.
[0031] This allows the protective cover 7 to slide within the elongated groove 6, thereby changing the distance between the two protective covers 7 in the width direction of the center plate 1.
[0032] When welding battery terminals, this fixture is placed on top of the battery, with the battery terminals inserted into the protective cover 7 and the battery terminals passing through the groove 5. Since the protective cover 7 is fitted over the battery terminals, it prevents solder slag from splashing onto the battery terminals during welding and also protects them. After the battery terminals pass through the groove 5, the welding area of the battery terminals is exposed around the perimeter, thus facilitating welding.
[0033] Example 2: Based on Example 1, referring to... Figure 1 As shown, a collar 8 is fixedly sleeved on the outer side of the protective cover 7 above the movable plate 4, and a screw 9 is threaded onto the collar 8, with the lower end of the screw 9 tightly abutting against the upper end of the movable plate 4.
[0034] Loosening screw 9 allows the cover 7 to slide within the elongated groove 6, thereby changing the distance between the two covers 7 in the width direction of the center plate 1. Tightening screw 9 positions the cover 7. Tightening screw 9 improves the stability of the cover 7.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
