Description

Technical Field

[0001] The invention relates to the field of blade production, in particular to a fully automatic positioning, clamping and detecting device for double guide blades. Background Art

[0002] The blade is one of the core components of an aircraft engine. Its curved surface shape and manufacturing accuracy directly determine the propulsion efficiency of the aircraft engine. Since the curved surface shape of the blade is a complex spatial surface, its blank is mostly cast or forged in one piece, and the consistency of cast / forged blades is poor, and the processing allowance is usually unpredictable, so it is not enough to meet the accuracy requirements of the processing benchmark, so that the blade has no processing or clamping benchmark throughout the body. According to the aviation blade manufacturing standard, the six point coordinates on the blade body need to be used to limit the six degrees of freedom of the blade space, so as to determine the blade processing benchmark. In the existing production mode, the blade is mainly manually pressed against the six-point positioning support tooling, and then the blade body or transition surface is pressed with a pressure plate, and then the six-point contact gap of the blade is detected with a feeler gauge. The gap space at each point is required to be ≤0.02mm, which can prove that the six-point positioning of the blade is completed, and then the production and processing in the machine tool is carried out. However, the manual operation of the above process is very cumbersome. The clearance of each positioning point cannot be guaranteed by manual clamping in one go, and repeated clamping confirmation is required. At the same time, in the blade automation production line, since each blade processing requires manual clamping and inspection, the blades cannot be processed continuously, which limits the possibility of unattended processing of blades, and greatly increases the cost of blade tooling and fixtures in the product, and cannot reduce the intensity of manual labor.

[0003] In addition, some blade detection tools have also appeared in the prior art, but these tools are usually flat-plate shaped as a whole. For example, patent CN103557766B discloses a method and device for detecting a guide blade channel of a welding structure, which includes a substrate, and relevant positioning and detection devices are arranged on the substrate. For example, patent CN108151619B discloses a detection device for detecting the contour of the inner edge of the guide blade, which includes a base, and relevant positioning and detection devices are arranged on the base. The above tools cannot meet the detection requirements of curved blades such as double guide blades. Summary of the invention
