Abstract

The invention discloses a clamp used for blade inspection. The clamp comprises an installation baseplate used for fixing with the rotation bench of a three-dimensional scanner. The installation baseplate is provided with a clamp body used for clamping a blade to be detected. The periphery of the clamp body is provided with a plurality of installation supporting columns which are arranged vertically. The bottom end of each installation supporting column is fixed with the installation baseplate. The installation supporting columns form an encirclement ring and the blade to be detected which is clamped by the clamp body is arranged in the encirclement ring. Each installation supporting column is pasted with a plurality of lighting points. The lighting points are used to indicate the positionof the blade to be detected which is clamped by the clamp body relative to the three-dimensional scanner. By using the clamp used for blade inspection, the detection steps of the blade to be detectedcan be simplified, detection is labor saving and time saving, the clamp can be repeatedly used, operation personnel do not need to manually adjust the placing position and the angle of the blade, thedetection steps are simple, detection time can be shortened, and detection efficiency and detection precision are increased.

Description

technical field

[0001] The invention relates to the technical field of fixtures, in particular to a fixture for blade detection. Background technique

[0002] In order to improve the accuracy and flexibility of aero-engine blade detection, a three-dimensional scanner is used to scan and detect the blades. Before the detection starts, firstly stick reflective dots on the surface of the blades to mark the far and near position of the blades relative to the scanner, then place the blades with reflective dots on the rotary table of the scanner, and finally turn on the scanner to inspect the blades. Scanning, the scanner reconstructs the three-dimensional entity of the blade according to the data obtained by scanning the blade, and compares the three-dimensional entity with the physical entity pre-stored in the system and analyzes the accuracy, and finally determines whether the scanned blade is qualified. Since the reflective points need to be pasted on the blades before scanni...
