ROTATION AND ELEVATION TOOL OF THE INDUSTRIAL ROBOT

摘要

The appts. comprises a frame connected to a robot arm movably suported by a frame-support. The frame-support is movalby mounted within an upstanding hollow sleeve of a stationary base, and a bearing is formed between an outer peripheral surface portion of the frame-support and an inner peripheral surface portion of the base hollow sleeve portion for slidably mounting the frame-support to undergo linear and angular sliding movements relative to the base hollow sleeve portion. A rotary motor effects angular driving movement of the frame-support member, and a linear motor effects linear movment of the frame-support member to accurately position the robot arm.
