  • Patent number: 9744602
    Abstract: The present invention provides a work piece chuck of manipulator in the field of mechanical technology. The chuck comprises a chuck sleeve and an ejector pin set within the chuck sleeve. An elastic clamping element is provided at the front end of the chuck sleeve. The ejector pin could move between a first position and a second position along the axial direction of the chuck sleeve. When the ejector pin is in the first position, the outer circumference of the ejector pin extrudes the clamping element to distort and expand outward to form an expansion state. When the ejector pin is in the second position, the outer circumference of the ejector pin is out of contact with the clamping element to restore the clamping element. The chuck has a number of advantages including firm connection, high reliability and high use value.

  • Patent number: 9193024
    Abstract: The present invention provides a surface processing system for a work piece in the mechanical technical field. The system comprises at least one group of polishing units. A manipulator and several polishers with different polishing precisions are provided on the polishing units. The polishers are arranged around the manipulator in turn. The work piece could be moved by the manipulator between the processing center and the polishing units. The machined work piece is loaded by the manipulator for one time when the manipulator is located at the processing center. When the manipulator is located at the polishing units, the manipulator keeps holding the work piece and transfers the work piece in a preset sequence to each polisher corresponding to the polishing unit where the manipulator is located. The surface of work pieces having different wall thicknesses and complex surfaces could be processed in a large batch with a high efficiency.
