ABSTRACT:
A positioning apparatus for positioning an arm of an industrial robot comprises a frame member connected to the robot arm and being movably supported by a frame-supporting member. The frame-supporting member is movably mounted within an upstanding hollow sleeve of a stationary base, and a bearing is formed between an outer peripheral surface portion of the frame-supporting member and an inner peripheral surface portion of the base hollow sleeve portion for slidably mounting the frame-supporting member to undergo linear and angular sliding movements relative to the base hollow sleeve portion. A rotary motor effects angular driving movement of the frame-supporting member, and a linear motor effects linear movement of the frame-supporting member to thereby accurately position the robot arm. By such a construction, the frame-supporting member is mounted for angular and linear sliding movements relative to the base hollow sleeve portion by a single bearing.
