Technical Field
[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a welding device for automotive parts manufacturing. Background Technology
[0002] In the automotive manufacturing industry, welding is an indispensable core process for connecting various metal parts. Its quality directly affects the structural strength, collision safety, fatigue durability, and assembly precision of the entire vehicle. As the automotive industry rapidly develops towards lightweighting, customization, and multi-platform co-production, the types of welding workpieces that a single production line needs to handle are increasing exponentially. These workpieces are not only diverse in materials, but also vary significantly in size and geometric shape. Traditional fixed tooling often falls short in the face of such highly diverse needs, and frequent changes and adjustments severely slow down the production pace. Therefore, it is urgent to develop a welding device for automotive parts production that is highly efficient and adaptable. Its core is to be able to quickly and stably fix workpieces of various sizes and shapes without complex adjustments or changes in fixtures, thereby significantly improving the overall efficiency of the production line while ensuring welding precision, and meeting the dual requirements of agile production and high-quality control in the modern automotive manufacturing industry. In existing technologies, the fixing methods used in automotive component welding fixtures mainly rely on pre-set rigid structures and limited adjustment capabilities. The most common is manually operated mechanical clamping systems, such as bolt clamping mechanisms, which require tightening bolts one by one to apply clamping force. In production lines pursuing automated welding, cylinder- or motor-driven power clamps are more commonly used. These clamps drive the jaws to open and close through pre-set linear motion mechanisms. The clamping position and stroke are determined by pre-set mechanical limits or program control points, and the adjustment range is fixed and limited. However, existing technologies generally have a prominent and critical problem: when dealing with diverse welding workpieces with large size ranges and significant differences in geometry, it is difficult to achieve fast and convenient welding. While conventional methods offer reliable clamping force without requiring additional tools or frequent component changes, for workpieces exceeding the preset clamping range or with irregular shapes, machine shutdown, manual replacement of fixture modules, and readjustment of jaw positions or travel limits are necessary. These cumbersome and time-consuming steps demand high operator skills and are prone to errors, affecting positioning accuracy. This frequent and time-consuming tooling switching and adjustment severely restricts production cycle time and equipment utilization, resulting in long idle waiting times. This problem is particularly prominent in small-batch, multi-variety production models, becoming one of the main bottlenecks in improving the overall efficiency of welding production lines and responding quickly to market changes. Therefore, a welding device for automotive parts production is proposed to address these issues. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a welding device for automobile parts production, which aims to improve the problem of inconsistent workpiece size and shape and difficulty in fixing in the welding process of the prior art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A welding apparatus for producing automotive parts includes a chassis, a protective mechanism inside the chassis, a support frame fixedly connected to the top of the chassis, and a clamping mechanism inside the support frame. The protective mechanism includes a storage slot located inside the chassis. A protective plate is slidably connected inside the storage slot. A circular groove is located inside the chassis. A sleeve is fixedly connected inside the circular groove. A sliding shaft is slidably connected inside the sleeve. A spring is installed inside the sleeve. A slider is fixedly connected to the side wall of the sliding shaft. A handle is fixedly connected to the side wall of the protective plate. The slider is slidably connected inside the protective plate.
[0005] As a further description of the above technical solution: The clamping mechanism includes a connecting rod slidably connected inside the support frame. A connecting block is fixedly connected to the top of the connecting rod, and a fixed shaft is fixedly connected to the side wall of the connecting block. An adjusting rod is provided on the side wall of the fixed shaft, and a sliding groove is opened inside the adjusting rod. The fixed shaft is disposed inside the sliding groove. A sliding frame is fixedly connected to the top of the support frame, and a clamping block is slidably connected to the side wall of the support frame. An installation shaft is fixedly connected to the side wall of the clamping block, and a welding plate is fixedly connected to the top of the support frame. One side of the adjusting rod is rotatably connected to the side wall of the installation shaft.
[0006] As a further description of the above technical solution: An electric slide rail is fixedly connected to the top of the chassis, a support column is slidably connected to the top of the electric slide rail, a robotic arm is provided at the bottom of the support column, and a welding foot is fixedly connected to the movable end of the robotic arm.
[0007] As a further description of the above technical solution: The chassis is equipped with a hydraulic rod, which is fixedly connected to the connecting rod.
[0008] As a further description of the above technical solution: The chassis is provided with a door on its side wall, and a handle is fixedly connected to the side wall of the door.
[0009] As a further description of the above technical solution: One end of the spring is fixedly connected to the inside of the sleeve, and the other end of the spring is fixedly connected to the side wall of the slide shaft.
[0010] As a further description of the above technical solution: A filter screen is fixedly connected inside the chassis to protect the interior of the chassis.
[0011] This utility model has the following beneficial effects: 1. In this utility model, the connecting rod is driven to move up and down by starting the hydraulic rod, so that the connecting block moves synchronously. At this time, the fixed shaft is offset in the slide groove with the vertical movement of the connecting block, pulling the clamping block to move horizontally on the sliding frame. The distance between the clamping blocks changes relatively, and the workpiece placed on the welding plate is fixed, achieving the effect of stable and fast fixing of the welding workpiece. This solves the problem of workpieces of different sizes and shapes being difficult to fix during the welding process, and improves the adaptability and efficiency of the equipment.
[0012] 2. In this utility model, the protective plate is pulled out of the storage slot by pulling up the handle. The slider is subjected to the pressure of the protective plate, which causes the spring to pull the slider back to the sleeve. After the protective plate reaches the preset height, the handle is stopped, the spring loses its force and resets, causing the slider to pop out, thus completing the height locking of the protective plate. This achieves the effect of conveniently adjusting the height of the protective plate, solves the problem of high temperature sparks flying during welding, and improves the safety of the equipment.

[0017] Reference Figures 1-3The clamping mechanism includes a connecting rod 12, which transmits hydraulic pressure to drive the clamping motion. The connecting rod 12 is slidably connected inside the support frame 10. The support frame 10 cooperates with the connecting rod 12 to perform linear guiding motion, achieving the effect of stably supporting the workpiece. A connecting block 13 is fixedly connected to the top of the connecting rod 12. The connecting block 13 is used to connect to the fixed shaft 14, providing a rigid support point. The fixed shaft 14 is fixedly connected to the side wall of the connecting block 13. The fixed shaft 14 cooperates with the adjusting rod 15 to perform rotational motion, achieving the effect of angle adjustment and force transmission. The adjusting rod 15 is provided on the side wall of the fixed shaft 14. The adjusting rod 15 is used to control the position of the clamping block 17. To achieve precise clamping force adjustment, the adjusting rod 15 has a groove 26 inside, which guides the sliding of the fixed shaft 14. The fixed shaft 14 is located inside the groove 26. A sliding frame 16 is fixedly connected to the top of the support frame 10, providing a sliding track for the clamping block 17 to achieve linear movement guidance. The clamping block 17 is slidably connected to the side wall of the support frame 10, directly clamping the workpiece and preventing welding displacement. A mounting shaft 18 is fixedly connected to the side wall of the clamping block 17, mounting the adjusting rod 15 and providing a rotation fulcrum. A welding plate 19 is fixedly connected to the top of the support frame 10 for placing the workpiece. This provides a stable welding platform. One side of the adjusting rod 15 is rotatably connected to the side wall of the mounting shaft 18. An electric slide rail 20 is fixedly connected to the top of the housing 1. The electric slide rail 20 is used to move the support column 21, achieving precise welding positioning.

The filter screen 27 is used to filter air impurities and prevent dust from entering the inside of the housing 1, thus protecting the inside of the housing 1.
[0018] Working principle: When using this equipment, first place the automotive parts to be welded above the welding plate 19. Then, activate the hydraulic rod 11. The hydraulic rod 11 drives the connecting rod 12 to move vertically up and down, causing the connecting block 13 to move up and down synchronously. This causes the fixed shaft 14 to slide inside the slide groove 26, causing the adjusting rod 15 to shift position. Because the mounting shaft 18 and the clamping block 17 are fixed in position, the adjusting rod 15 pulls the clamping block 17 to move horizontally on the sliding frame 16. The clamping block 17 moves closer and closer to the automotive parts to be welded, stopping when it comes into contact with them, thus fixing the automotive parts in place. After the position is fixed, pull up the handle 9 to apply an upward pulling force to the protective plate 4, causing the slider 8 to be squeezed. This compresses the spring 7, causing the slider 8 to retract into the sleeve 5. The protective plate 4 moves upward in the storage groove 2. After the height of the protective plate 4 is raised, stop pulling up the handle 9. The slider 8 is no longer under force, the spring 7 loses its squeezing force and resets, and the slider 8 pops out from the sleeve 5, thus locking the height of the protective plate 4.
[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
