Embodiment Construction

[0020] The following examples refer to Figure 1~3 .

[0021] The machine tool with integrated blisk-disc composite numerical control milling composite structure of the present invention includes plunger milling and side milling devices, a disc milling device 15 , a fixture 6 , a rotary table 7 , a horizontal table 9 , a bed base and a column 1 .

[0022] The overall structure of the machine tool is L-shaped, with four linear axes, three rotary axes and one electric spindle SP. The four linear axes are X axis, X1 axis, Y axis and Z axis respectively, and the three rotation axes are A axis, B axis and C axis respectively. The plunge milling and side milling servo motor 2 provides power for the plunge milling and side milling device. The Y-axis machine tool ram 13 and the Y-axis servo motor and ball screw nut pair 3 are fastened on the bed rear base 24 with screws, the Y-axis machine tool guide rail 12 is directly stuck on the Y-axis machine tool ram 13, and the column 1 is sc...

Abstract

The invention discloses a composite numerical control milling composite-structure machine tool for a blisk, aiming to solve the technical problem of low efficiency of the traditional universal five-coordinate machine tool during blisk machining. A technical scheme is as follows, a disk milling device (15) is added on the basis of a plunge milling device and a side milling device. The machine tool highly integrates the processes of disk milling, plunge milling and side milling, the disk milling is used for large-margin removal and slotting machining; the plunge milling is used for slot expanding machining and curved surface forming; and the side milling is used for semifinishing to realize edge removing and back gouging. According to the invention, a large-torque and high-rigidity disk / plunge milling dual-power-head structure of the forms a high-efficiency powerful composite numerical control machine tool to realize one-step clamping and positioning, so that the rough finish and the semifinishing of the blisk can be completed.

Description

technical field [0001] The invention relates to a numerically controlled milling machine tool for an integral blisk, in particular to a machine tool with a composite numerical control milling structure for an integral blisk. Background technique [0002] The blisk is the core component of a high-thrust-to-weight ratio, high-performance engine, and it is also a key part for weight reduction, efficiency increase and performance improvement of major equipment in the fields of aerospace, defense, energy, and power. Compared with the traditional blade and hub assembly structure, the integral blisk omits the tenon, tenon groove and corresponding connecting parts, reduces the weight, improves the thrust-to-weight ratio, and improves the working life, safety and reliability of the engine. However, due to its structure Complexity, narrow passages, poor openness, etc., make its manufacturing technology an international problem. Therefore, realizing high-efficiency, high-quality, and ...
