[0017] As Figure 1 and Figure 2 shown, this embodiment provides a welding tooling based on the turbine housing valve rocker arm component. During the working process of the welding tooling, both the axial clearance of the valve rocker arm component and its welding angle are controlled. The welding tooling includes a support bolt 11 provided at one end of the main body 1 of the tooling. After the support bolt 11 and the main body 1 of the tooling are vertically assembled, a positioning boss 12 is further provided at the joint between them. At the same time, a limit block 2 is provided at one end of the main body 1 of the tooling, and the main body 1 of the tooling and the limit block 2 are fixedly connected by bolts;

After the turbine housing valve rocker arm component is assembled on the positioning boss 12, as Figure 3 , Figure 4As shown in the figure, the positioning plate 3 is arranged on the air outlet side of the volute valve rocker arm component. An installation groove 31 is provided inside the positioning plate 3. One end of the rocker arm positioning block 5 is arranged in the installation groove 31 and is positioned by a cylindrical pin 32 in the installation groove 31 and is fixedly connected by bolts. A characteristic structure of an angle limiting surface 51 and a positioning card slot 52 is provided on the other end surface of the rocker arm positioning block 5, which is convenient for controlling the welding gap and angle of the rocker arm component.

[0019] The volute valve rocker arm component is radially positioned and assembled on the positioning boss 12 of the welding fixture by using the hole structure in the middle, restricting the automatic movement in the x and y axes.

[0020] At the same time, the side surface of the volute valve rocker arm component is in frictional contact with the limiting block 2, and the cooperation with the positioning boss 12 restricts the automatic rotation degree around the z axis.
