A movable sleeve 107 is installed on the outer wall of the positioning pressure plate 103, and the movable sleeve 107 is sleeved on the outside of the inner rod 106. A fixed base plate 109 is installed on the inner rod 106, and a positioning spring 110 is arranged between the fixed base plate 109 and the movable sleeve 107.

[0041] The working principle or use method of this embodiment: The welding process is carried out on a device composed of a waterwheel welding processing frame 1 and a processing positioning table 101. When the welded part 102 is on the processing positioning table 101, according to the size of the welded part 102, a plurality of adjustment openings 105 suitable for inserting the inner plug rod 106 are opened on the processing positioning table 101. When the inner plug rod 106 is inserted into the corresponding hole, the movable sleeve 107 is in a connected state with the positioning pressure plate 103, and the fixed bottom plate 109 is installed on the inner plug rod 106 and pressed on the upper surface of the processing positioning table 101 to limit the inner plug rod 106. Then the threaded cylinder 111 is rotated, and the lower part of the inner plug rod 106 is provided with an external thread that matches the threaded cylinder 111. When the threaded cylinder 111 is threadedly connected to the outside of the inner rod 106 and the threaded cylinder 111 is pressed on the lower surface of the processing positioning platform 101, the lower part of the inner rod 106 is fixed to complete the installation, and the other end of the movable sleeve 107 is sleeved on the outside of the inner rod 106.
