Problems solved by technology

There is a problem like this: whether the personal experience is rich or not plays a key role in the qualification judgment of the blade to be tested, if in case the consideration factor is not comprehensive and the artificial judgment of the measurement operator is unreasonable, it is easy to cause inaccurate evaluation of the measurement data; the present invention can Clearly separate the accurate eccentricity errors of the tested parts in the A direction and the B direction, and then compare them with the allowable tolerances required by the design, and the results are directly used to judge whether the tested quadruple guide vane is qualified or not

Abstract

The invention discloses a device for detecting the arc benchmark of a quadruple guide vane. The device comprises a bottom plate (15), a sliding plate (3) arranged on the surface of the bottom plate and used for arranging a to-be-detected quadruple guide vane, a detecting plate (6) arranged on the surface of the bottom plate and used for providing a mobile guide rail surface for a detector, A-direction sliding guide adjusting components (4) arranged on the surface of the bottom plate and used for adjusting the position of the sliding plate through sliding in an direction A, B-direction sliding guide adjusting components (8) arranged on the surface of the bottom plate and used for adjusting the position of the detecting plate through sliding in an direction B, and a simulated zero meter aligning block (7) arranged on the detecting plate. By using the device to detect and adjust the benchmark arc surface of a large flange plate of a quadruple guide vane, detection can be completed with high quality, the detection operation can be simplified, and the detection efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of quadruple guide vane processing, in particular to the detection technology of the processing reference arc surface of the quadruple guide vane, in particular to a device for detecting the reference arc surface of the quadruple guide vane. Background technique [0002] The quadruple guide vanes are finished by casting rough parts through finishing machining. The processing process is to use the six original positioning points of the quadruple guide vanes to locate and process the large end edge plates of the quadruple guide vanes, and then use the arc of the large end margin plates to The other parts of the blade are processed on the basis of the surface. Before machining other parts of the blade based on the arc surface of the large end edge plate, it is necessary to detect the reference arc surface (reference arc surface) to detect the deviation of the machined guide vane arc surface relative to the theo...
