Problems solved by technology

The movement trajectory control of the cutting head of the series mechanism is established in the Cartesian coordinate system. The mathematical operation of the action control process is simple, but the mechanical structure is complex and heavy, the dynamic response speed of the equipment is poor, and the life of the parts is low. Transmission, all need expensive 3D laser cutting head

Embodiment Construction

[0038] first to figure 1 , image 3 The coordinate system shown in is defined as follows:

[0039] X axis——the movement direction of the beam 2 along the X guide rail on the fuselage 1;

[0040] Y axis——the movement direction of the Y-axis slide plate 3 along the Y guide rail on the beam 2;

[0041] Z axis——the movement direction of the Z-axis slide 4 along the Z guide rail on the Y-axis slide 3;

[0042] A-axis—the cross 5 is connected with the Z-axis slide 4 through a rotating pair, and can rotate within the range of ±90°;

[0043] C-axis—the laser head mounting support 8 is connected with the cross 5 through a rotating pair, and can rotate within the range of ±90°;

[0044] Among them, the X-axis motion control is the same as that of the ordinary gantry-type two-dimensional laser cutting machine, while the Y, Z, A, and C four-axis motion is realized through a parallel mechanism. Four controllable linear drive devices 6 that are movably connected to the crossbeam 2 and ...

Abstract

The invention discloses an imperfect degree-of-freedom parallel connection five-axis computerized numerical control laser cutting machine, relating to a laser cutting machine with an imperfect degree-of-freedom parallel connection five- axis drive mechanism. The laser cutting machine comprises a machine body, an X-direction guide rail, a beam, a laser cutting heat and a controller, wherein the side surface of the beam is provided with a Y-direction guide rail, the laser cutting head is movably connected with the Y-direction guide rail through an imperfect degree-of-freedom parallel connection mechanism; and the imperfect degree-of-freedom parallel connection mechanism comprises a Y-axis slide carriage device, a Z-axis slide carriage device, a cross, a laser head installing support, four equilong connecting rods and four linear driving devices. The invention realizes five-axis motion of the conventional laser cutting head through the imperfect degree-of-freedom parallel connection device, wherein the beam realizes basic X-direction motion relative to the motion of the machine body; four drive blocks respectively move and drive the laser heat installing support to make translation or rotation motion through respective connecting rods, mutual motion among the four drive blocks realizes combined motion of an Y axis, a Z axis, an A axis and a C axis; and the imperfect degree-of-freedom parallel connection five-axis computerized numerical control laser cutting machine has skilled structures of all parts, large rigidity and small inertia, so that the motion precision can be ensured.

Description

technical field [0001] The invention relates to a driving mechanism of a laser cutting machine, in particular to a laser cutting machine with a parallel five-axis driving mechanism with few degrees of freedom. Background technique [0002] Due to its advantages such as fast speed, narrow slit, small heat-affected zone, good verticality of slit edge, smooth cutting edge, and wide range of cutting materials, laser cutting technology is widely used in many fields. With the development of laser application technology, laser cutting of three-dimensional space curves has been widely used in many fields such as automobile industry and aerospace industry abroad due to its advanced, flexible and adaptable characteristics. Using 3D laser cutting can not only save samples and tooling equipment, but also greatly shorten the production preparation cycle. [0003] At present, most of the three-dimensional laser cutting machines and the host transmission mechanism are connected in se...
