[0002] The automobile oil pipe is a pipe connecting the gasoline pump and the engine fuel nozzle, which provides fuel and power oil to the steering gear, thereby reducing steering resistance. The brake oil pipe is a pipe connecting the brake pump and the brake pad support. When the driver steps on the brake, the brake pump applies pressure to the brake pad through the brake oil, and the two brake pads squeeze the brake disc to achieve the purpose of slowing down the vehicle.

[0003] In the automobile manufacturing process, the welding of oil pipes is one of the key steps. Generally, automobile oil pipes are set as curved special-shaped pipe fittings, and the head elbow and the tail are connected to the middle pipe fittings by welding. The existing operators use tongs to clamp the pipe fittings. When welding one end, the tongs clamp the pipe fittings at both ends, and then step on the flamethrower to spray fire at the connecting part. Before spraying fire, the welding machine is coated to facilitate burning of the welding machine, thereby realizing the splicing between the two pipe fittings.

[0004] In actual use, most existing welding processes rely on manual operation, and the welding end is easily affected by manual operation, resulting in deviation of the welding point, affecting the welding quality and reducing the welding efficiency. Utility Model Content
