Embodiment Construction

[0019] The following examples refer to Figure 1~2 .

[0020] The vertical structure machine tool for integral blisk composite numerical control milling of the present invention includes a disk milling device 21 , a plunge milling and side milling device 5 , a fixture 8 , a rotary table 9 , a horizontal table, a bed base 17 and a column 24 .

[0021] The overall blisk composite CNC milling vertical structure machine tool has four linear axes, which are X axis, Y1 axis, Y2 axis and Z axis. Three rotation axes, namely A axis, B axis and C axis. The Z-axis servo motor 1 is installed on the top of the column 24, the Z-axis machine tool ram 3 and the Z-axis ball screw nut pair 2 are installed on the front end of the column 24 with screws, and the Z-axis machine tool guide rail 4 is directly stuck on the Z-axis machine tool ram 3. The plunge milling and side milling device 5 is installed on the guide rail 4 of the Z-axis machine tool through screws and the Z-axis ball screw nut pa...

Abstract

The invention discloses a blisk composite numerical-control milling vertical-structured machine tool used for solving a technical problem of low efficiency of a current general blisk processing method employing a five-coordinate machine tool. The invention provides a technical scheme that a disc milling device (21) is added on the basis of plunge and side milling devices (5). According to the invention, disc milling, plunge milling, and side milling technologies are highly integrated. Disc milling is used in large margin resection and grooving processing. Plunge milling is used in groove expansion processing and curved surface forming. Side milling is used in semi-finishing, and edge-trimming. With a large-torque high-rigidity disc milling / plunge milling double power head structure, the blisk high-efficiency high-power composite numerical-control milling machine tool is formed. With the machine tool, one-step fixture positioning is realized, and blisk rough processing and semi-finishing can be achieved.

Description

technical field [0001] The invention relates to a numerical control milling machine tool for integral blisks, in particular to a vertical structure machine tool for composite numerical control milling of integral blisks. 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 low-...
