Latest Patents

One of Han's latest inventions is the Ball Screw Clamping Device. This device aims to provide a clamp screw that minimizes the loss of clamping force. It allows for a powerful clamping force with minimal rotational input and can be operated manually. The design effectively utilizes the reverse thrust of the rotating tool to achieve sufficient clamping without excessive force. When the flange ring contacts the object to be attached, the rotation of the threaded member halts, entering a clamping state. The operating ring is then screw-fed by balls moving around the thread grooves, exerting pressure on the flange ring through the restraining ring, thus securing the tool.

Another significant invention is the Counter Centrifugal Chuck and Mounting Systems. This chuck features a body with an axial recess and a transverse opening that intersects the recess. It includes first and second cam members that partially reside within the transverse opening, which have passages that compress a cylindrical, slitted inner sleeve. This sleeve holds the tool shank during the chuck's rotation. The inner sleeve is spring-biased for axial movement and has a tapered upper end that engages a tapered retainer sleeve, retaining the tool shank when the chuck is not rotating. An outer sleeve, composed of co-molded inner and outer shells, moves axially about the body. A remote actuating member facilitates the axial movement of both sleeves for easy insertion or withdrawal of the tool shank.
