Problems solved by technology
[0002] Blades are one of the most important parts of turbine machinery such as aero-engines. They have the characteristics of complex shapes and high machining accuracy. However, during the processing of the mortise and tenon teeth of the blades, it takes a long time to load, unload, and align these production preparations. , and the number of blades of each aero-engine is huge, so there is a requirement for production efficiency. At present, it takes a long time for the preparatory work of loading, unloading and alignment before wire cutting, so it is difficult to achieve efficient production

The invention relates to a fixing device and method for linear cutting of a blade tenon. The device comprises a bottom plate, reference angle iron, a lateral positioning block, an axial positioning block, a front positioning platform and a rear positioning platform; the reference angle iron is placed on the bottom plate, and the lateral positioning block and the axial positioning block are connected to the bottom plate through bolts and attached to positioning faces limited by the lateral positioning block and the axial positioning block; the side surface of the bottom plate is connected witha lower screw seat through a screw and is provided with a threaded hole; the upper portion of the reference angle iron is connected with an upper screw base through screws, the front positioning platform, the rear positioning platform, a blade body profile positioning pin on the reference angle iron and the axial positioning ball jointly position the blade, and puller screws are installed at the top and the bottom of the reference angle iron respectively to fix the blade. According to the method, the stability of the machining process and the consistency of the machining size can be improved,and the machining efficiency of linear cutting tenon teeth is improved.
Description
technical field [0001] The invention belongs to the technical field of aero-engine blade processing, and in particular relates to a fixing device and method for wire-cut blade tenons. Background technique [0002] Blades are one of the most important parts of turbine machinery such as aero-engines. They have the characteristics of complex shapes and high machining accuracy. However, during the processing of the mortise and tenon teeth of the blades, it takes a long time to load, unload, and align these production preparations. , and the number of blades of each aero-engine is huge, so the production efficiency is required. However, it is difficult to achieve high-efficiency production due to the long time required for loading, unloading and alignment before wire cutting. Therefore, there is an urgent need for a fixing device for wire-cut blade tenons to solve the above problems. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the ...
