Abstract
A work rotating device for a laser beam machine utilizes a work-supporting bed rotatable by a speed reducer mounted on a frame adapted to rest on a table of the laser beam machine. In a first embodiment, the speed reducer is fixed to the frame, and the frame has two orthogonal surfaces alternatively engageable with the table so that the axis of rotation of the work can be either vertical or horizontal. In a second embodiment, the speed reducer is manually tiltable in the frame by direct manual rotation of a shaft on which the speed reducer is mounted. In a third embodiment, the speed reducer through which the work is rotated is mounted on a shaft which is connected to a handwheel through another speed reducer. In a fourth embodiment, the speed reducer through which the work is rotated is tilted by a servo motor operating through a speed reducer.
