REFLECTION APPARATUS FOR LASER WELDER

摘要

PURPOSE: A reflection apparatus used for a laser welder is provided to expand life span of the reflection apparatus by fabricating a surface of a mirror installed in a laser welder as a polygonal surface. CONSTITUTION: A circular duct is connected to a base. The circular duct is connected to a rectangular duct. The rectangular duct is connected to a plurality of vertical ducts. A torch head(5) is provided at a tip of the vertical duct. A strip is fixed by means of a clamp, which is coupled with a clamp cylinder(6). A reflection unit is installed in the circular duct and the rectangular duct, respectively. Laser beam reflected from the reflection unit is introduced into the torch head(5). A focusing mirror(8) is provided in the torch head(5). A mirror head(16) is rotatably fixed to a mirror fixing plate(15). Cooling water is circulated through the mirror head(16).
