Abstract
The invention discloses a steam turbine low pressure diaphragm sleeve gas guide inclined hole processing and positioning guide device, and relates to a low pressure diaphragm sleeve gas guide inclined hole processing and positioning guide device used for a steam turbine. The problem that a gas guide incline hole cannot be positioned and guided when an all-purpose drill is used for processing a steam turbine low pressure diaphragm sleeve and the like is solved. The device comprises an upper plate, a vertical plate, a lower plate, a first bolt and a second bolt, wherein the upper plate, the vertical plate and the lower plate form a half I-shaped structure; the first bolt and the second bolt penetrate through two bolt holes in the front of the lower plate; a guide positioning inclined hole is formed in the vertical plate; the trepanning position of the guide positioning inclined hole in the outer side face of the vertical plate is higher than the trepanning position of the guide positioning inclined hole in the inner side face of the vertical plate; the inner side of the vertical plate is a convex arc surface with the same curvature as a diaphragm; a triangular convex part is arranged at the middle position of the front end of the upper plate; a triangular convex part is arranged at the middle position of the front end of the lower plate. The device has the advantages that the positioning is convenient and accurate, the efficiency is high, the guide effect is realized, and a drill bit is prevented from being deflected in the machining process, and the device is suitable for a conventional small-sized equipment all-purpose drill.
