Machine-tool with a device for changing workpieces

摘要

#CMT# #/CMT# A cutting machine comprises a workpiece changer (27) having a receiving element for workpieces and/or workpiece palettes (31, 32). The receiving element which is in the form of single gripper or double gripper (26) can be pivoted about a vertical axis and can be linearly shifted in a plane normal to such axis. An intermediate space between sidewalls of cutting machine is divided by a transverse wall (19) or a door which is closed during workpiece machining and is partly open into front machining area (20) and rear supply area (21) during the workpiece changing operation. #CMT# : #/CMT# A cutting machine comprises a workpiece changer for shifting workpieces and/or workpiece palettes to be processed between transfer site(s) outside the cutting machine and a horizontally immobile workpiece table (22), and a tool spindle arranged on a slide arrangement able to be power driven at least in the two horizontal directions. The workpiece changer has a receiving element for the workpieces and/or workpiece palettes. The receiving element which is in the form of single gripper or double gripper can be pivoted about a vertical axis and can be linearly shifted in a plane normal to such axis. The slide arrangement runs on two parallel sidewalls of the cutting machine designed in the form of a gantry machine. The sidewalls laterally delimit a machining area. An intermediate space between the sidewalls is divided by a transverse wall or by a door which is closed during workpiece machining and is partly open into a front machining area and a rear supply area during the workpiece changing operation. The radius of pivoting of the receiving element, engaging a workpiece or a workpiece palette, extends partly into the supply area. #CMT#USE : #/CMT# For machining workpieces. #CMT#ADVANTAGE : #/CMT# The workpiece changers needs less room and does not hinder the machining operation or endanger the machine minder. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure is a side elevation of a cutting machine. 19 : Transverse wall 20 : Front machining area 21 : Rear supply area 22 : Workpiece table 26 : Double gripper 27 : Workpiece changer 31, 32 : Workpiece palettes.
