Description

Technical Field

[0001] This utility model relates to the field of automotive processing technology, specifically a welding fixture for the side beam of an automotive battery casing. Background Technology

[0002] The power battery pack located in the chassis consists of two parts: an upper cover and a lower shell. The battery shell is the load-bearing component of the power battery in new energy vehicles, mainly used to protect the lithium battery from damage when subjected to external collisions and compression. Currently, most pure electric vehicles choose steel or aluminum alloy materials for the protective shell of the battery pack to ensure the safety of the chassis power battery. Although this can protect the power battery to a large extent, it also faces the challenges of the battery pack's weight, which adds unnecessary curb weight, increases power consumption, reduces range, and even affects the vehicle's handling to varying degrees. When users process the side beams of the car battery shell, they need to weld them, and during welding, they need to clamp them, requiring the use of professional clamps.

[0003] An investigation revealed that a Chinese utility model patent (CN220921381U) discloses a welding fixture for a car battery casing side beam. The fixture includes a base, a rotating rod rotatably connected to the outer surface of the base, a support platform fixedly connected to the outer surface of the rotating rod, and a fixing plate fixedly connected to the outer surface of the support platform. The fixing plate has multiple fixing openings on its outer surface. This utility model relates to the field of clamping technology. By setting a fixing device, the device is installed in the corresponding fixing opening according to the shape of the casing side beam. Pressing the extrusion block causes it to rotate. Through the sliding between the outer surface of the extrusion block and the outer surface of the slider, the slider slides within the fixing block. The bottom end of the clamping block first contacts the casing side beam, and during the slider's movement, the clamping block rotates on the inner surface of the slider until the upper end of the clamping block contacts the outer surface of the upper end of the casing side beam. The casing side beam is clamped and fixed on all sides and at the top, preventing loosening during welding, resulting in better clamping and preventing vertical shaking during welding.

[0004] The aforementioned patent is not perfect in terms of its function when users need to perform precise positioning, which will affect the accuracy of the user's welding and reduce the quality of the processing. It is also not stable enough when the user needs to place the fixture, causing it to shake, which will affect the user's use of the welding fixture.

[0005] Therefore, this utility model provides a welding fixture for the side beam of an automotive battery casing to solve the above-mentioned problems. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This utility model provides a welding fixture for the side beam of an automotive battery case. A first telescopic rod allows the upper clamping frame to extend and retract, flexibly adjusting the distance between the upper clamping frame and the corresponding lower clamping structure. This enables precise clamping of side beams of different specifications of automotive battery cases, ensuring the side beam remains stable during welding, preventing shaking or displacement, and improving welding accuracy. Simultaneously, symmetrically arranged positioning plates are fixedly connected to one side of the welding fixture body, with multiple positioning openings. These openings can be used for preliminary positioning of the side beam or other related components, facilitating subsequent clamping and welding operations, making the welding position more precise, effectively reducing welding errors, and thus improving welding quality. Furthermore, a second telescopic rod is connected to the mounting frame, allowing adjustment of the position of the mounting frame and related components, further optimizing the overall layout of the fixture, improving the convenience and efficiency of welding operations, and meeting the user's needs for flexible adjustment and precise positioning, thereby improving welding quality and efficiency.

[0018] This utility model provides a welding fixture for the side beam of an automotive battery casing. A support rod fixedly connected to one side of the main body of the welding fixture provides a stable foundation for the entire fixture, ensuring stability during operation and preventing tipping or shaking, thus guaranteeing smooth welding operations. A protective shell fixedly connected to one side of the mounting frame provides excellent protection for important components such as the motor, preventing damage to the motor from welding spatter and dust, extending the equipment's service life. Simultaneously, the motor is connected to the protective shell via symmetrically arranged connecting blocks. This design not only enhances the stability of the connection between the motor and the protective shell but also ensures more even force distribution on the motor during operation, reducing the risk of failure due to vibration. Furthermore, a limiting block is movably connected to the mounting frame, restricting the range of movement of the mounting frame to prevent excessive movement that could affect welding accuracy or cause equipment damage, further ensuring the safety and stability of the welding process. This meets the user's needs for stable support and reliable protection, guaranteeing safe and stable use during the welding process. Attached Figure Description

[0031] In this embodiment, a second telescopic rod 17 is fixedly connected to one side of the welding fixture body 1, and the second telescopic rod 17 is connected to the mounting frame 5. A positioning opening 16 is provided on one side of the positioning plate 15, and there are multiple positioning openings 16.

[0032] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a processing frame 11 is fixedly connected to one side of the fixed base plate 10, a first telescopic rod 12 is fixedly connected to one side of the processing frame 11, an upper clamping frame 13 is fixedly connected to one side of the first telescopic rod 12, and a stop block 14 is fixedly connected to one side of the upper clamping frame 13.

[0033] In this embodiment, the motor 9 is connected to the protective shell 7 via the connecting block 8, and the connecting block 8 is symmetrically arranged with the vertical center line of the motor 9 as the axis of symmetry.

[0034] like Figure 1-5 As shown, when a user needs to use a welding fixture for a car battery casing side beam, a support rod 2 is fixedly connected to one side of the welding fixture body 1. The support rod 2 provides a stable support base for the entire fixture, ensuring that the fixture remains stable during operation. A controller 3 is fixedly connected to one side of the support rod 2. The operator can control various components of the entire fixture through the controller 3, such as controlling the extension and retraction of the first telescopic rod 12 and the second telescopic rod 17, as well as the start and stop of the motor 9, to achieve automated operation of the fixture.

When welding the side beam, the side beam is placed in the corresponding position on the processing frame 11. The controller 3 controls the first telescopic rod 12 to extend and retract, causing the upper clamping frame 13 to move downward. Although the corresponding lower clamping structure on the processing frame 11 is not explicitly mentioned, it can be inferred from the principle of clamping that there is a fit to clamp and fix the side beam. A stop block 14 is fixedly connected to one side of the upper clamping frame 13. The stop block 14 can...
