Abstract

The invention provides a novel clamping tool used for three-coordinate detection of a static blade profile, which can effectively solve the problems of complicated clamping and unstable blade positioning of the traditional detection tool and can ensure the stability of detection reference and integrity of detection information. The novel clamping tool comprises a bottom plate and is characterizedin that supporting seats are arranged at two horizontal sides of the bottom plate; a double-center seat and a single-center seat are respectively arranged on the supporting seats at two sides; two moving centers are arranged on the double-center seat; and a single center is arranged on the single-center seat.

Description

technical field [0001] The invention relates to the field of blade profile detection tools, in particular to a novel clamping tool for three-coordinate detection of the profile of a stationary blade. Background technique [0002] The existing three-coordinate measuring tool for the profile of the stationary blade is positioned by the rounded corner of the steam inlet side, and a V-shaped block is set on each of the large and small ends of the blade to support the blade, and then placed on the three-coordinate detection platform, wherein the side of the V-shaped block A magnetic suction device is provided to hold the blade to ensure the stability of the blade during the detection process. In the three-coordinate detection, the three-center hole and the axial positioning surface of the big end are used as the reference to detect the cross-section profile of each gear in the inner back arc. Its disadvantages are: after the blade surface is placed on the two V-shaped blocks, a ...
