Specifically, the disassembly mechanism also includes: a connecting assembly is provided on the threaded sleeve 5, specifically, the connecting assembly includes a connecting plate 6, the connecting plate 6 is welded to the top of the threaded sleeve 5, and an insert 10 is welded to the top of the connecting plate 6.

[0045] See also Figure 5 , the fixing assembly is provided on the threaded sleeve 5 and cooperates with the connecting assembly. Specifically, the fixing assembly includes two symmetrically provided threaded columns 11, which are symmetrically welded to the top of the connecting plate 6. The outer wall of the threaded column 11 is provided with a limiting sleeve 12. The fixing plate 7 is fixedly connected to the connecting plate 6 through the threaded holes opened on the two side walls and the threads of the threaded column 11 and the limiting sleeve 12, thereby realizing the disassembly and replacement of the clamp;

[0046] In this embodiment: by symmetrically welding two threaded columns 11 to the top of the connecting plate 6, a limiting sleeve 12 is provided on the outer wall of the threaded column 11, and the fixed plate 7 is fixedly connected to the connecting plate 6 through the threaded holes opened on the two side walls and the threads of the threaded column 11 and the limiting sleeve 12. For the fixture of the turbine casing that generates a lot of heat during long-term contact processing, it can be disassembled and replaced, thereby improving the subsequent processing efficiency.

[0047] See also Figure 3 The lifting mechanism is provided on the threaded sleeve 5 and is interconnected with the disassembly mechanism, which is used to achieve turbine housings of different heights. Specifically, the lifting mechanism also includes: a driving assembly is provided on the fixed plate 7, specifically, the driving assembly includes two symmetrically provided L-shaped auxiliary plates 13, the two L-shaped auxiliary plates 13 are symmetrically welded to the bottom of the fixed plate 7, a cylinder 14 is welded to the top of the L-shaped auxiliary plate 13, a U-shaped lifting plate 15 is welded to the output end of the top of the cylinder 14, and a clamping plate 19 is welded to the side wall of the U-shaped lifting plate 15;
