Irregular curved surface workpiece laser marking device

Abstract

The invention provides an irregular curved surface workpiece laser marking device which comprises a workbench, a double-shaft rotating assembly, a lifting lead screw guide rail assembly and a laser head assembly. The double-shaft rotating assembly is arranged in the middle of the workbench, and the laser head assembly is fixed to one side of the lifting lead screw guide rail assembly and located above the double-shaft rotating assembly; the double-shaft rotating assembly comprises a double-lug support, a first rotating assembly, a second rotating assembly and an irregular curved surface workpiece, the first rotating assembly is fixed to the double-lug support through symmetrically-arranged bearing seats, the second rotating assembly is installed on the first rotating assembly through symmetrically-arranged rotating shafts and connecting plates, and the irregular curved surface workpiece can be internally supported and clamped through three groups of spherical fingers. Under the synergistic effect of the lifting lead screw guide rail assembly and the double-shaft rotating assembly, the irregular curved surface workpiece achieves online high-precision automatic laser marking, and theproduction efficiency is greatly improved.
