[0002] Components are widely used in industries such as automotive, telecommunications, healthcare, watches, mobile phones, and computers. Unlike standard components, precision components are more precise and are therefore more suitable for industries with high precision requirements. Components and workpieces are often connected through welding, riveting, flange connections, or bonding, with welding being the most common. Welding involves applying heat, pressure, or both, with or without filler material, to achieve a permanent bond between the atoms of the workpiece.

[0003] For example, the welding operation of the flange of the exhaust pipe fittings of automobile parts or the intake connecting pipe of the exhaust port and the air inlet requires the use of a positioning device to clamp and position the pipe parts, and then cooperate with the welding gun to perform the welding operation.

They are unable to perform clamping and fixing operations according to different clamping points of pipe fittings of different lengths. Usually, it is necessary to design multiple clamps with different clamping point positions to clamp the pipe fittings to be welded, which brings unnecessary cost and storage space occupation, poor applicability and cumbersome operation.
