Latest Patents

Yumin Liu holds a patent for a "Quick-stop cutting device for a lathe." This invention features a comprehensive design that includes a base, bottom plate, front side plate, rear side plate, right side plate, left side plate, top fixed plate, tool bar, cam lever, buffer spring, cylindrical guide rail, adjusting nut, first locking nut, double end stud, second locking nut, pressure spring, pressing plate, hold-down bolt, and pin shaft. The cam lever supports the tool bar before the tool falls. When tool falling is required, the cam lever is rotated through external force. When the cam lever rotates over a certain position, the tool bar instantaneously loses supporting force. Under strong pressure from the pressure spring, the tool bar drops the tool with great acceleration, separating it from the cutting region in a short period of time, effectively freezing the cutting root. This innovation enhances safety and efficiency in lathe operations.
