Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a welding device for automotive parts. Background Technology

[0002] In the automotive manufacturing industry, the welding quality of automotive parts directly affects the overall performance, safety, and reliability of a vehicle. As one of the key components of a car, the precision and efficiency of the welding process for automotive exhaust parts play a crucial role in controlling vehicle emissions and optimizing engine performance. Traditional automotive parts welding equipment has many limitations. In terms of welding precision, the welding torch of traditional equipment lacks flexibility and is difficult to adjust precisely in multiple directions. This often results in inaccurate welding, such as failing to reach the designated welding position when welding complex-shaped parts like automotive exhaust parts that require precise welding location. This leads to inaccurate welding, resulting in problems such as incomplete welds and missed welds, which seriously affect welding quality and reduce the performance and service life of the automotive exhaust system. The loading and parts conveying processes of traditional welding equipment mostly rely on manual operation or simple mechanical conveying methods, with low automation levels. This can easily lead to problems such as untimely loading and inaccurate positioning, affecting the continuity and stability of the welding process. Summary of the Invention

The three-axis cylinder 51 drives the pneumatic gripper 52 to grab the parts on the second conveyor 53 and place them on the work box 23. Inside the work box 23, the third servo motor 30 drives the bidirectional lead screw 27 to rotate. Two movable sliders 28, which are symmetrically installed on the outside of the bidirectional lead screw 27, move synchronously towards or away from each other along the bidirectional lead screw 27. The clamping block 32, which is fixed to the top of the movable slider 28, moves accordingly to clamp or release the parts. The second limit rod 29, which is symmetrically slidably set inside the movable slider 28, restricts its movement direction to ensure linear motion.The accordion cloth 31 prevents welding debris from entering the work box 23 and clamps and fixes the car exhaust pipe parts held by the pneumatic gripper 52.

The linear modules at each level work together to enable the welding gun 39 to move in multiple directions such as X, Y, and Z to accurately reach the welding position of the parts. The welding gun 39 performs welding operations on the two clamped car exhaust parts. After welding, the first linear module 11 drives the moving plate 9 and the second support frame 10 to move, making it convenient to remove the welded exhaust pipe parts.
