In-place blade profile contour detection device suitable for robot to clamp blade

Abstract

The invention discloses an in-place blade profile contour detection device suitable for a robot to clamp a blade, and belongs to the technical field of grinding and polishing robot detection equipment. The in-place blade profile contour detection device comprises a line laser contour measurement mechanism and a controller thereof which are used for accurately collecting blade profile contour data, processing the original data and then intelligently splicing and converting the original data, a high-precision lifting driving mechanism and a controller thereof which are mounted on a main device base and used for adjusting the vertical position of line laser to measure the blade profile contours of different sections of the blade, a high-resolution transposition driving mechanism and a controller thereof which are used for accurately collecting 360-degree blade profile contour data of a certain section of the blade, and a robot wrist auxiliary locking mechanism and a controller thereof which are used for assisting in fixing a sixth shaft of the robot for clamping the blade and guaranteeing that the blade is clamped stably in the measuring process. According to the blade profile contour detection device, the six-degree-of-freedom industrial robot clamps the blade for blade profile contour detection, in-situ detection of the engine blade can be achieved, mechanical positioning errors caused by repeated clamping are avoided, the device manufacturing cost is reduced, the detection efficiency is improved, meanwhile, the detection precision of the blade profile contour is guaranteed, and the intelligent level of grinding and polishing machining of the robot is improved.

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. After intelligently planning the processing trajectory of the workpiece to be processed, high-precision grinding and polishing is carri...

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
