Axis system based on five-axis linkage processing center and five-axis linkage processing center comprising same

Abstract

The invention discloses an axis system based on a five-axis linkage processing center, and mainly solves the problems that a current five-axis linkage processing center is poor in performance, easy to damage processing parts, and the like. The axis system based on the five-axis linkage processing center comprises three linear axes, namely an X axis, a Y axis and a Z axis, a revolving axis, namely an A axis, a swinging axis, namely a B axis, wherein the B axis and the Y axis are distributed above a machine tool and are positioned above a processed part; the Y axis direction is perpendicular to the B axis swing direction; the B axis is used for driving a principal axis and a tool to swing; the Y axis is used for driving the principal axis and the tool to carry out front-rear linear motion; the X axis, the Z axis and the A axis are distributed below the machine tool; the A axis is used for driving the processed part to carry out revolving motion; the X axis is positioned below the processed part and is used for driving the processed part to carry out left-right linear motion in a horizontal direction; and the Z axis is used for driving the processed part to carry out up-down linear motion in a perpendicular direction. The axis system is reasonable in design, reliable in performance and suitable for being popularized and applied.

Description

technical field [0001] The invention relates to a five-axis linkage machining center, in particular to a five-axis linkage machining center based on the axis system of the five-axis linkage machining center and the five-axis linkage machining center. Background technique [0002] The axis system of the five-axis linkage blade machining center consists of X, Y, Z linear axes, rotary A axis, and swing B axis. The rotary A axis is used to clamp the blade parts for rotary motion, and the swing B axis is used to drive the main shaft and the tool for swing motion. [0003] The overall layout structure of the existing five-axis linkage blade machining center has two types: [0004] (1) The X-axis, Z-axis and swing B-axis are arranged above the blade parts to be processed, and the Y-axis and the rotary A-axis are arranged under the blade parts to be processed. The X-axis drags the Z-axis and the swing B-axis to move left and right, and the X-axis guide rails are arranged on the ho...

AI Technical Summary

Problems solved by technology

[0006] (1) The mass of the moving parts dragged by the X-axis is large, the moving acceleration is low, and the dynamic response characteristics are poor, which affects the five-axis linkage performance of the whole machine;

[0007] (2) The swing B-axis is superimposed on the X-axis, and the swing direction is parallel to the movement direction of the X-axis, causing the pendulum effect of the swing B-axis, which will affect the positioning accuracy and acceleration performance of the swing B-axis when the X-axis accelerates and decelerates;

[0008] (3) The Z-axis drives the swing, and the B-axis drives the main shaft and the cutter to be arranged above the blade parts. When an unexpected situation such as a sudden external power failure occurs, the main shaft and the tool will inevitably move downward instantly, thus damaging the expensive blade. ;

[0012] (1) The mass of the moving parts integrated on the X-axis is too large, the load is too high, and the dynamic response characteristics are poor. At the same time, there are too many superimposed connection links of the shaft system above the processed blade parts, which reduces the overall cutting rigidity of the machine tool and greatly affects the whole machine. Excellent five-axis linkage performance;

[0013] (2) The swing B-axis is superimposed on the X-axis, and the swing direction is parallel to the movement direction of the X-axis, causing the pendulum effect of the swing B-axis, which will affect the positioning accuracy and acceleration performance of the swing B-axis when the X-axis accelerates and decelerates
