Robot arm for incorporation in industrial robots - has secure power circuit guide and compact construction allowing max. travel of tool connector

摘要

The robot arm has power circuits to motors and an attaching element for tools, workpieces and interchangeable claws. The robot arm can be designed as a component for industrial robots, such as portal robots and has a secure power circuit guide and even after mounting on basic equipment with small external dimensions provides the largest possible travel for the tool connector. For such a design the E-axis motor (21E) has an angled drive (69) and a toothed wheel (22) for a power belt (23) inside the tubular arm body (6). The power belt connects a toothed wheel (24) on an axis (26E) of an E-axis drive with a rotating fork and a swivelling head. Control and energy circuit lines are guided past the motor (21E) to a connecting flange (39) for the interchangeable claw system and also to a P-axis motor. USE/ADVANTAGE - Functions as a robot arm for industrial robots, e.g. line or portal robots. Safe guidance of the power circuits. Allows the largest possible travel of the tool connector even after integration in basic equipment with small external dimensions.
