Detailed Description
The following describes specific embodiments of the present invention with reference to the drawings.
In the welding process of the turbine shell, the welding angle and the gap of the final part meet the requirements, and the jacking and the pressing of the bypass valve are reliable and stable. The design concept of the automatic welding fixture is explained as follows:
as shown in fig. 1 to 4, an automatic welding fixture includes a bottom plate 1 and a vertical plate assembly 2 disposed perpendicular to the bottom plate 1, wherein the bottom plate 1 is substantially n-shaped in a top view, the vertical plate assembly 2 is disposed in a middle portion of the n-shaped, a corner cylinder assembly 3 is further disposed on one side of the vertical plate assembly 2, and a guide rod cylinder assembly 4 and a pen-shaped cylinder assembly 5 are disposed on two end portions of the n-shaped, respectively, the vertical plate assembly 2 and the three cylinder assemblies enclose a receiving space for clamping and fixing a welding workpiece, which is a turbine shell in this embodiment.
