Process and arrangement for removing excess material from castings
First Claim
Patent Images
1. An apparatus for removing excess material from a casting, comprising:
- a rotating abrasive cut-off disk;
a tool holder carrying said abrasive cut-off disk and provided with means enabling linear advance of said cut-off disk relative to said casting on said tool holder to remove excess material from said casting;
a multiple-arm industrial orbit carrying said tool holder at a free end of said multiple-arm industrial robot, said multiple-arm industrial robot having a multiplicity of mutually displaceable angularly adjustable parts enabling positioning of said tool holder at a predetermined location adjacent said casting; and
centrally control and lockable hydraulic actuators between said parts whereby all of said mutually displaceable angularly adjustable parts can be rigidly locked relative to one another under central control upon positioning of said tool holder at said predetermined location for subsequent linear displacement of said cut-of disk relative to si casting on said tool holder to remove said excess material, said multiple-arm industrial robot having a stand pivotable about a vertical axis relative to a stationary support and forming one pair of said mutually displaceable angularly adjustable parts, an articulated leer supported on said stand and pivotable about a horizontal axis and forming with said stand at least one other pair of said mutually displaceable angularly adjustable parts, said tool holder forming with said leer another pair of said mutually displaceable angularly adjustable parts.

Abstract
A cut-off arrangement comprises a multiple-arm industrial robot (100) with a support arm in the form of an articulated lever (7). One end of the lever is mounted in a stanchion (8) so as to pivot about a horizontal and a vertical axis. The workpiece holder (18), on which the cutting-off disk (13) moves linearly on sliding means (22, 23), is hingedly supported at the other end of the lever. The adjusting devices of the robot (100) are hydraulic cylinders (11; 16; 17; 19) or hydraulic servomotors (20, 21) which can be centrally controlled and immobilized.
