Abstract

The invention discloses a disk-milling main shaft device of a vane-integrated disk numerical control machine tool, which adopts a concave-shaped disk-milling main shaft box structure, wherein a plurality of gear shafts in the box are distributed in parallel; a gear pair on each shaft is a helical gear; the helical gears of the shafts are engaged; the bevel gear pair and the engaged helical gears on the gear shafts transfer power to the disk-milling cutter shaft; a servo motor is arranged on the left upper part of the outer box of the power transmission mechanism to drive a synchronous belt and a worm-gear pair to move; the disk-milling main shaft box oscillates around the axial line; due to application of the tooth coupling structure, safety and reliability in the machining process of the disk milling can be ensured; the disk-milling main shaft device can keep good rigidity under action of high cutting force and high torque; at the same time, the simple cutter-changing structure and form can effectively reduce cutter-changing time; when the disk-milling main shaft device is applied in the processing of the vane-integrated disk, the processing efficiency of the vane-integrated disk can be improved drastically; the processing cost can be reduced; therefore, the device has good application value.

Description

technical field [0001] The invention belongs to the technical field of process equipment structure design and manufacture, and relates to a disc milling spindle device of an integral blisk numerical control machine tool. technical background [0002] As the core component of a new generation of aero-engines, blisks are increasingly used in the aviation industry. Its application is not only an important measure to improve engine performance, simplify structure, but also improve its reliability; at the same time, its processing efficiency and production cost have also become important research contents of domestic R&D units and production enterprises. [0003] The overall blisk channel grooving rough machining removes a huge amount of material, accounting for more than 90% of the total removal amount. The rough machining process should complete the removal of most of the material as quickly and efficiently as possible. On the premise of meeting the requirements of the radius ...
