[0002] A bellows is a tubular elastic element with transverse corrugations, which is made of foldable corrugated sheets connected along the direction of expansion and contraction. Depending on the material, bellows can be divided into metal bellows and plastic bellows. Its core function is to realize various engineering needs such as pressure measurement, displacement compensation, vibration reduction and noise reduction through elastic deformation. In the process of bellows processing, welding equipment is required to weld the bellows together with components such as flanges and sensors to form a bellows assembly.

[0003] Chinese patent CN219005160U discloses a welding fixture for corrugated pipe assemblies, including: a flange positioning mechanism, which includes a base, a first cylinder fixedly mounted on one side of the base, a limit member movably connected to the other side of the base, a fixed frame fixedly connected to the top of the base, and a pneumatic gripper fixedly mounted on the right side of the fixed frame; a corrugated pipe positioning mechanism, which includes a first clamp and a second clamp, the second clamp being fixedly mounted on the top of the first clamp; and a tailpipe positioning mechanism, which includes a support base. This utility model has the advantage of good protection and solves the problems of existing bellows assembly welding fixtures, which are prone to causing indentations on the flange surface of the bellows assembly during use, affecting the sealing effect of the bellows assembly, and making it inconvenient to install sensors at the tail section of the bellows assembly, thus reducing the assembly efficiency of the bellows assembly. However, the above-mentioned fixtures are not convenient for aligning bellows and flanges of different diameters and corresponding sensors and other components during use, which affects the practicality of the fixtures to a certain extent. Therefore, in order to solve the above problems, this utility model proposes a bellows assembly welding fixture. Utility Model Content
