Abstract

The invention discloses a measuring tool and a method for establishing a coordinate system, comprising a positioning frame, an end face positioning block and a clamp; the tops of the clamp and the end face positioning block protrude from the top of the positioning frame, the end face positioning block is located on the side of the clamp, and the end face positioning block faces the end of the clamp. The top of the side is provided with a stepped surface, the side of the stepped surface is the end face positioning surface, the bottom surface of the stepped surface is provided with a first convex block, and the top of the first convex block is a first arc positioning surface; the clamp includes a left clamp and a right clamp, and the left clamp and The front and rear sides of the top surface of the right clamp are provided with protrusions, the opposite surfaces of the two protrusions on the same clamp are the clamping surface and the side positioning surface, and the left clamp or the right clamp is provided with a second convex block and a third convex block, The tops of the second bump and the third bump are the second arc positioning surface and the third arc positioning surface, and the first arc positioning surface, the second arc positioning surface and the third arc positioning surface are consistent with the curvature of the bottom surface of the blade . Increased stability of blade clamping.

Description

technical field [0001] The invention belongs to the field of blade detection, and relates to a measuring tool and a method for establishing a coordinate system. Background technique [0002] Aero-engine double-edge plate blades have various structures. Some blades use a thin upper edge plate (less than 3mm) for the measurement reference, and the lower edge plate is a curved surface. It not only delays the testing time, but also greatly increases the labor intensity of workers. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, provide a measuring tool and a method for establishing a coordinate system, increase the stability of blade clamping, and provide a guarantee for high-efficiency, stable and accurate detection of double-edge plate blades in large quantities . [0004] To achieve the above object, the present invention adopts the following technical solutions to realize: [0005] ...
