Description
Technical Field
The invention relates to the technical field of numerical control machine tool equipment, in particular to a novel vertical-horizontal conversion five-axis linkage machining center.
Background
The five-axis linkage machining center shaft system consists of XYZ linear shafts, a rotary C shaft and a swing A shaft (or a main shaft 10). The rotary shaft C is used for clamping a part to do rotary motion, and the swing shaft A (or the main shaft 10) is used for following the cutter to do swing motion.
The overall layout structure of the existing five-axis linkage machining center has various types: however, the following 2 structures are common:
the first step is that a crown block type wall body base bed body is adopted, a Z-axis main shaft is arranged in front of a sliding saddle and moves up and down, an X-axis sliding saddle is arranged on a cross beam and moves left and right, a Y-axis cross beam stretches over the base bed body and moves back and forth integrally, and an A/C axis is of a cradle turntable structure and is fixedly supported on a vertical wall at the front part of the base bed body.
The disadvantages of this structure: firstly, the moving part dragged by the Y axis has large mass, low moving acceleration and poor dynamic response characteristic, thereby influencing the five-axis linkage performance of the whole machine; secondly, the swing C axis is superposed on the A axis, the swing direction is parallel to the X axis movement direction, so that the pendulum effect of the swing C axis is caused, and the positioning precision and the acceleration performance of the swing main shaft 10 are influenced when the X axis moves in an acceleration and deceleration manner; thirdly, the bed structure of the crown block type wall body base is complex, the integral processing manufacturability of the casting is poor, the precision is not easy to guarantee, fourthly, the A/C shaft is of a cradle turntable structure, the size of the processed part is easily limited by the size of the turntable, and the processing range of large parts is not easy to meet.
And (II) a gantry frame beam structure is adopted, a Z-axis main shaft is arranged in front of a saddle and moves up and down, an X-axis saddle is arranged on a beam of the gantry frame and moves left and right, the beam of the gantry frame is integrally supported on a base bed body, an A/C axis is a cradle turntable structure and is integrally arranged on a base central line and moves back and forth and is a Y axis.
The disadvantages of this structure: firstly, the moving parts integrated on the Y axis are too large in mass and too high in load, the dynamic response characteristic is poor, and meanwhile, the number of superposed connection links of shafting above the machined part is too large, so that the integral cutting rigidity of the machine tool is reduced, and the performance of five-axis linkage of the whole machine is greatly influenced; secondly, the swing C axis is superposed on the X axis, the swing direction is parallel to the motion direction of the X axis, so that the pendulum effect of the swing main shaft 10 is caused, the positioning precision and the acceleration performance of the swing main shaft 10 can be influenced when the X axis moves at an accelerated speed, thirdly, the A/C axis is of a cradle turntable structure, the size of a machined part is easily limited by the size of the turntable, and the machining range of a large part is not easy to meet.
