Description

Technical Field

[0001] The invention relates to the technical field of welding devices, in particular to a welding device for processing pipeline fixing clips of vehicle oil pipes. Background Art

[0002] The pipeline fixing clips of vehicle oil pipes, also called oil pipe clips or oil pipe fixing clamps, are mainly used to fix the oil pipes to prevent them from loosening or falling off due to vibration during driving. At the same time, they can also reduce the friction between the oil pipes and other parts of the vehicle and extend the service life of the oil pipes. In addition, some specially designed oil pipe fixing clips also have a sealing function to prevent oil leakage. When processing the pipeline fixing clips of vehicle oil pipes, it is necessary to weld and fix the clips with other parts to facilitate installation and fixation.

[0003] However, when welding this special-shaped clip using the existing welding device for processing pipeline fixing clips, due to its unique structural design, it is difficult to achieve completely stable positioning using conventional fixing methods. If the clip cannot be firmly fixed, it is easy to shake or shift. This unstable state will lead to problems such as uneven welds and insufficient strength. It may also affect the installation accuracy and service life of the entire assembly due to position deviation. Summary of the invention
