The invention belongs to the ultrasonic-assisted processing technology of a composite blade fatigue test piece, and relates to a finishing positioning device and method for a blade fatigue test piece. The positioning device for finishing machining of a composite blade fatigue test piece of the present invention includes a plane processing positioning assembly and a drilling processing positioning assembly which are both arranged on an ultrasonic milling equipment platform. The present invention selects the bushing hole at the root of the blade and the profile of a certain section of the blade as the positioning reference, uses the plane processing positioning component to accurately position and fix the blade, and uses the drilling processing positioning component to accurately position and fix the blade, and then uses The ultrasonic milling equipment mills and drills the blade fatigue test piece. For the first time, the invention realizes the ultrasonic-assisted processing of the composite blade fatigue test piece, and can realize the precise positioning of the composite material blade fatigue test piece on the ultrasonic milling equipment platform. The operation is convenient and fast, and quick clamping and disassembly can be realized.
Description
technical field [0001] The invention belongs to the ultrasonic-assisted processing technology of a composite blade fatigue test piece, and relates to a finishing positioning device and method for a blade fatigue test piece. Background technique [0002] With the wide application and continuous mass production of fiber composite materials in the aviation field, the traditional processing technology based on manual milling has obviously failed, not only low efficiency, poor precision, but also low tool durability. For hole making and surface processing, high-speed drilling and milling can improve processing efficiency, but due to the relatively large cutting force, when the tool tends to wear, there will still be quality problems such as delamination damage, which will affect the processing. efficiency and increase production costs. Ultrasonic cutting technology is a process technology developed internationally in the past ten years. The basic principle is to use an electroni...
