Abstract

The invention discloses a combined clamp for online measuring of aero-engine blade processing and is used for solving the technical problem that existing blade numerical-control-processing precise positioning clamps are poor in practicability. The technical scheme includes that the combined clamp comprises displacement sensors, a guide rail base, a sensor switching module, a slider and supporting screws, the guide rail base is composed of four guide rails with rectangular sections, the slider is mounted on the guide rail base and matched with the same, and can freely slide on the same, the supporting screws are mounted on the slider and are freely adjustable in height, and the displacement sensors are fixed on the supporting screws through the sensor switching module. Support is provided by the supporting screws, so that the technical problem of deformation of a knife due to poor rigidity of a blade body in the process of cutting is solved; due to use of the displacement sensors, online monitoring during blade processing is realized; a tenon clamping module is replaceable, so that troublesomeness in replacing the whole clamp during processing of blades different in type is avoided.

Description

technical field [0001] The invention relates to an aeroengine blade machining fixture, in particular to a combined fixture for on-line measurement of aeroengine blade machining. Background technique [0002] As one of the core components of an aero-engine, the manufacturing level of the engine blade plays a vital role in the overall performance of the engine. In order to meet the requirements of lightweight, aeroengine blades are mostly thin-walled structures made of titanium alloys and other materials, which brings great difficulties to blade processing. In order to make the processing of engine blades meet the strict design requirements, it is essential to use matching precision fixtures for processing. At present, the blade clamps used in factories generally have the following problems: each specification blade needs to be specially made as a supporting fixture, which is expensive; The deformation of the blade is monitored online while the blade is being processed.
