Horizontal type five-axis combined machining center with turning plate structure

Abstract

The invention discloses a horizontal type five-axis combined machining center with a turning plate structure. A bed body is arranged horizontally, and front-back movemenet of a turning plate working table on the bed body is Z-axis movement; a stand column is mounted at the rear part of the bed body, and a saddle moves left and right on the stand column to realize X-axis movement; a spindle box drives a spindle to move up and down on the saddle to realize Y-axis movement; the turning plate working table moves around the X axis to realize A-axis movement; the spindle box moves around the Y axisto realize B-axis movement. By means of linkage of the X axis, the Y axis, the Z axis, the A axis and the B axis, efficient cutting machining for aircraft structural parts can be realized; a tool magazine and a tool changing manipulator are distributed on the left side of the bed body, automatic tool change of the machining center is realized, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a five-axis compound machining center with a horizontal flap structure. Background technique [0002] The horizontal five-axis machining center is a double-oscillating head horizontal five-axis machining center with two rotating axes at the spindle end, and a horizontal five-axis machining center with a single-oscillating head and a rotary table structure with one rotating axis arranged at the spindle end and the table end. In the center, in order to meet the needs of large cutting force and high torque for cutting workpieces, the structural size of the swing head is generally designed to be relatively large, and the structure is also relatively complicated, resulting in long overhangs and poor rigidity of the swing head and spindle. [0003] At present, the horizontal machining center adopts a single ball screw to drive the turntable, so that the driving force cannot ac...

[0002] The horizontal five-axis machining center is a double-oscillating head horizontal five-axis machining center with two rotating axes at the spindle end, and a horizontal five-axis machining center with a single-oscillating head and a rotary table structure with one rotating axis arranged at the spindle end and the table end. In the center, in order to meet the needs of large cutting force and high torque for cutting workpieces, the structural size of the swing head is generally designed to be relatively large, and the structure is also relatively complicated, resulting in long overhangs of the swing head and the spindle, and poor rigidity

[0003] At present, the horizontal machining center adopts a single ball screw to drive the turntable, so that the driving force cannot accurately act on the center of gravity of the moving parts, so it is easy to produce a torsional tendency during high-speed chip cutting, causing vibration of the machine tool and making the machine tool larger. bending and deformation of the parts, and at the same time have a certain impact on the accuracy and life of the turntable
