Special machine tool for wire cutting of aviation grille parts

Abstract

The invention relates to a machine tool special for aviation grating type part linear cutting. The machine tool comprises an electronic control system, a lathe bed, X-axis, Y-axis and Z-axis moving mechanisms, a workbench, a wire holder mechanism and a workpiece clamping tool. The Z-axis moving mechanism comprises a stand column, a Z-axis driving motor, a pair of Z-axis connecting blocks and a Z-axis moving lead screw. The wire holder mechanism comprises an upper wire arm, a lower wire arm and a wire holder base. The upper wire arm and the lower wire arm are horizontally arranged in the Z-axis direction in a spaced mode and arranged in the X-axis direction in a staggered mode. The workpiece clamping tool is arranged on the inner side of the top of the workbench in a matched mode and is composed of at least one pair of symmetric tool clamping arms. The machine tool is simple and reasonable in structural design, convenient to use, high in applicability, workpiece machining efficiency and precision, capable of effectively lowering the production cost and improving the product quality and suitable for application and popularization.

Description

technical field [0001] The invention relates to a novel special wire cutting machine tool, in particular to a special wire cutting machine tool for aerospace grid parts. Background technique [0002] At present, the grid plate commonly used in aviation manufacturing has always been a difficult problem in processing, especially some parts with large angles, many and dense holes, and large plate dimensions. If EDM is used, no matter in terms of time and cost Let's face it, it's all very unsatisfactory. Then we turned our thinking to wire cutting, which has fast processing, good dimensional accuracy, and relatively controllable cost. [0003] The actual depth of the cutting surface of wire-cutting gratings is very shallow, and the existing wire-cutting gratings still has the following common problems in machine tool structure: [0004] (1) The vertical direction of the upper and lower wire arms is coaxial, and it is easy to interfere with the grid plate that needs to be place...

AI Technical Summary

Problems solved by technology

[0004] (1) The vertical direction of the upper and lower wire arms is coaxial, and it is easy to interfere with the grid plate that needs to be placed obliquely;

[0005] (2) At present, the wire cutting is driven by X-Y two-axis CNC, and the Z-axis CNC drive cannot realize the avoidance space;

[0006] (3) Even if a machine tool with a longer distance between the upper and lower wire arms is used on the stroke, it is difficult to break through the tension and economy of the molybdenum wire during cutting
