Description

Technical Field

[0001] The utility model relates to the technical field of stator blade processing, in particular to a positioning fixture for stator blade processing. Background Art

[0002] Stator blades are a general term for blades directly mounted on the inner wall of the cylinder, on the cylinder, or embedded in the baffle. Stator blades and rotor blades form the flow section of the steam turbine. Steam expands in the stator blade cascade, converting thermal energy into kinetic energy. Reaction turbine stator blades are directly mounted on the inner wall of the cylinder. Impulse turbine stator blades are mounted on the cylinder for the first stage, with the remaining stages embedded in the baffle. The high-pressure section stator blades are manufactured using processes such as cutting, cold drawing, precision casting, and die pressing, then embedded in the baffle and welded securely. When the low-pressure section uses a cast baffle, the stator blades are cast between the plate and the outer edge.

[0003] At present, when processing the first to-be-processed part and the second to-be-processed part of the mounting portion on the stator blade, since the stator blade has many irregular shapes and each component is thin-walled, it is impossible to effectively provide a positioning reference, and it is difficult to position and clamp the stator blade. When processing the stator blade, the clamping and positioning stability of the stator blade is poor, which leads to low production efficiency of the stator blade. Therefore, a positioning fixture for stator blade processing is needed to improve the above problems. Utility Model Content
