Title: Work pallet for laser beam machine
Inventor: ITO MASAOKI
IPC: B23K26/10
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To prevent a work pallet from being deformed by thermal expansion even when the work pallet is irradiated with the laser beam by providing a middle frame in which beam members are assembled on the inner side of an external frame of the work pallet in a lattice shape, and providing a shielding cover to shield the laser beam on the middle frame. SOLUTION: A middle frame 5 is of welded structure in which beam members 9 are assembled in a lattice shape. A shielding cover 7A to shield the laser beam is loaded immediately on the beam members 9 through a spacer 13 provided on a back side. When a work W is machined by laser beam, the laser beam is shielded by the shielding cover 7A. Even when the temperature of the shielding cover 7A rises, the heat is little transferred to the beam members 9 by the heat insulation effect of an air layer between the shielding cover 7A and the beam members 9. Thus, the middle frame comprising the beam members 9 is not thermally expanded. A work pallet 1 is not thermally deformed, and impossible or defective cutting of the work can be prevented.
