Five-axis linkage laser cutter

Abstract

The invention discloses a five-axis linkage laser cutter which comprises a laser, optical fiber, a laser head and a five-axis machining platform; the five-axis machining platform comprises a platform base, a Y-axis movement module, an X-axis movement module, a Z-axis lifting module, an A-axis rotation module, a C-axis rotation module and a turnover module. Power output shafts of turnover module driving motors of the turnover modules are connected with connection surfaces of expansion rods, and contact surfaces of the expansion rods clamp the two sides of a workpiece, so that accuracy control on a turnover angle of the circular arc or spherical workpiece can be realized through the turnover module driving motors; and the turnover modules are arranged at the two ends of a rotating axis of an A shaft, so that the workpiece does not deviate in the X axis, Y axis, Z axis or C axis direction, the machining after the workpiece is turned over is facilitated, the working efficiency of the laser is improved, and the influence on the machining accuracy due to the fact that the workpiece is turned over is reduced.

Description

Technical field [0001] The invention relates to the technical field of laser cutters, in particular to a five-axis linkage laser cutter. Background technique [0002] The five-axis linkage laser cutter is a processing instrument that uses a platform for coordinated movement of the workpiece along three linear axes and two rotation axes. The workpiece is melted by a focused high-power density laser beam to realize cutting and engraving of the workpiece. Compared with single-sided machining with three-axis linkage, five-axis linkage realizes three-dimensional processing of the workpiece, increases the processing surface of the workpiece, improves processing efficiency, and has the processing capability for workpieces with complex three-dimensional shapes; [0003] In the prior art, the five-axis linkage laser cutter can only process the five sides of the workpiece. If the bottom surface of the workpiece needs to be processed, the processing needs to be stopped, the workpiece is turne...
