Fixtures/Tooling Details

Motoman Robotics provided two sets of custom fixtures – one per cell. Fixtures adjust automatically to handle various part sizes. Two or three hydraulic clamps engage to hold each part, depending on part size. Fixtures also include retractable end stops, and powered rollers with variable feed drive to assist with loading and unloading. Fixtures allow part to be captured and rotated 180º to permit robots to access welds on bottom of parts.
