An in-situ blade profile detection device suitable for robot gripping blades

Abstract

The invention discloses an in-situ blade profile detection device suitable for a robot clamping a blade, including a line laser profile measurement mechanism and a controller thereof, which are used to accurately collect blade profile data, and intelligently splice and transform the original data after processing ; The high-precision lifting drive mechanism and its controller are installed on the base of the main device to adjust the vertical position of the line laser to measure the blade profile of different sections of the blade; the high-resolution indexing drive mechanism and its controller are used to realize Accurate collection of 360-degree airfoil profile data of a certain section of the blade; the auxiliary locking mechanism of the robot wrist and its controller are used to assist in fixing the sixth axis of the robot that clamps the blade, ensuring stable blade clamping during the measurement process.

Description

technical field [0001] The invention relates to the technical field of robot processing equipment, in particular to engine blade in-position detection and measurement equipment. Background technique [0002] Robot intelligent grinding and polishing processing technology has the advantages of high efficiency, strong flexibility, good flexibility, large operating space, low cost, and the combination of various external sensors can ensure processing quality and part consistency. It is an emerging complex parts grinding and polishing Processing methods. At present, the mainstream robot processing methods are divided into two types. One is to clamp tools by robots. This method is mainly suitable for processing some large and complex structural parts, such as marine propeller blades, wind power blades, etc.; the other is to clamp tools by robots. The workpiece to be processed, after the intelligent planning of the processing trajectory, performs high-precision grinding and polish...

Problems solved by technology

However, the equipment used to detect the contour curve of the airfoil is mostly offline detection equipment. When the workpiece is detected, it needs to be removed from the manufacturing fixture and replaced on the measuring fixture. Due to the multiple clamping and positioning processes , will inevitably affect the final machining accuracy of the parts; and the existing online detection equipment for a small number of airfoil profiles is mainly designed for CNC machine tools
