Embodiment Construction

[0025]A thin-walled blade parts of the present invention is precision processing flexible tooling, mainly including a tank mechanism, auxiliary support rotating mechanism, a multi-bolt clamping mechanism, and a lead rail rail mechanism. Here the examples referenceFigure 1 ~ 10 .

[0026]Such asfigure 1 As shown, a main view of the device of the present invention. Among them, the groove mechanism is composed of a cylindrical boss 1, a bolt 2, and a gauze 3. There is a cylindrical boss 1 at the bottom of the groove 3, and the cylindrical boss 1 is sandwiched with a triangular chuck 11, and the grooved groove 3 is made according to the shape of the hoe 4, and the trench 3 cooperates with the hoe 4, and the bolt 2 passes through the groove. 3 The bottom threaded hole will top the hoe 4, so that the groove 3 is more secure with the hoe 4. For multi-bolt clamping mechanisms, the auxiliary support rotating mechanism and the lead rail rail mechanism willFigure 2 ~ 9description.

Abstract

The invention discloses a flexible tool for precision machining of a blade body of a thin-walled blade part. The flexible tool comprises a mortise mechanism, a multi-bolt clamping mechanism, an auxiliary support rotating mechanism and a lead screw guide rail mechanism, wherein a plurality of flexible telescopic rods are arranged in the auxiliary support rotating mechanism, and the flexible telescopic rods have a pressure sensing function. The multi-bolt clamping mechanism is adopted for clamping a blade crown, and the auxiliary support rotating mechanism is adopted for auxiliary support of the blade body, and the lead screw guide rail mechanism is used as a base of the auxiliary support rotating mechanism so that the auxiliary support rotating mechanism is moved in the required direction. When a certain part of the blade body needs to be supported, the auxiliary support rotating mechanism can be moved to the designated part of the blade body through control over the lead screw guide rail mechanism for auxiliary support of the blade body. According to the flexible tool, on one hand, it can be guaranteed that machining vibration and distortion are avoided during machining of the thin-walled blade part, on the other hand, clamping and dismounting of workpieces are facilitated, and the machining quality and machining efficiency of the thin-walled blade part are improved.

Description

Technical field[0001]The present invention belongs to the technical field of aerospace engine complex and thin-walled parts, and specific relates to a thin-walled blade part of the blade of the flexible tooling.Background technique[0002]The blade part is the key to the aerospace engine, and its important component is present in the aerospace engine manufacturing field. Aviation engine components are in a working environment such as high temperature, high pressure, high rotation speed, so that the performance requirements of blade parts in the service process are met, and the quality of parts processing is to ensure the reliability of the engine. Prerequisites. Air engine is critical, important parts are mostly complicated to reduce energy consumption and increase the performance of the aircraft performance, especially blade parts. The thin wall of the blade has a large wall thickness, a weak rigidity, complex structure, and uses a total of difficult to process materials such as tita...
