Abstract

The invention discloses a three-dimensional five-axle 3D laser cutting machine. The machine comprises a base, a worktable, a mounting frame and a cutting head; the worktable is slidingly connected with the base; the adjustment of the laser cutting head in three-dimensional five-axle directions is realized through a Y-axle mounting frame, a Z-axle mounting frame, a C-axle pipeline and a B-axle pipeline; the C-axle pipeline and the B-axle pipeline are connected with a cutting head main body through a right-angled joint; a reflecting mirror and a zooming lens module are arranged in the right-angled joint; a total optical path is shortened; the laser energy loss is reduced; collision preventing blocks are arranged in three-dimensional directions for limiting the moving travel of the cutting head; the Y-axle mounting frame is provided with a protecting mechanism for protecting the Z-axle mounting frame; the moving travel on a Z axle is limited through a tension value; and the laser cuttingmachine is more compact in overall structure and simpler in multi-directional angle control method algorithm, improves the control precision, and is provided with multiple protections for protecting equipment to prolong the service life of the equipment.

Description

technical field [0001] The invention relates to the field of laser cutting, in particular to a three-dimensional five-axis 3D laser cutting machine. Background technique [0002] High-power laser cutting has become the mainstay equipment for sheet metal processing today, and its high processing efficiency and high precision are widely favored by the market. With the improvement of workpiece cutting requirements, the cutting requirements have been improved from two-dimensional cutting to three-dimensional cutting. Robotic three-dimensional cutting can meet the requirements of low precision and efficiency in the above fields with its advanced, flexible and fast flexible processing characteristics. , but for the processing of devices with relatively high precision and efficiency requirements, especially for the cutting and processing of three-dimensional workpieces with complex spatial surfaces, the existing ordinary three-dimensional laser cutting machines usually use laser cu...

Problems solved by technology

However, in large-scale laser cutting equipment, the cutting range of the laser cutting head is relatively large and the volume of its overall linkage components is relatively large. The spatial positioning is realized simply by changing the position of the laser cutting head, and the position adjustment path of the laser cutting head is complicated. It makes the laser cutting head unstable when adjusting its position, and the accuracy of laser cutting is reduced.

[0003] The position adjustment structure of the existing three-dimensional laser cutting machine is complex overall, which makes the adjustment path complicated, and the algorithm cannot accurately control the fixed-point adjustment angle to maintain a safe distance between the cutting head and the workpiece. The operator’s life is safe and fully automatic control is realized. The equipment operator inputs parameters to cut during operation, but the automatic control device is easy to cause equipment damage due to operator’s wrong parameters during operation. The existing 3D laser cutting machine is Equipment protection is not satisfactory
