1results about How to "Control contact force" patented technology

The utility model discloses a kind of adjustable force quick moving type micrometer, including ruler frame, measuring rod, adjusting handle and force adjusting mechanism, measuring rod is slidably connected in ruler frame, adjusting handle is rotatably connected in ruler frame one end, force adjusting mechanism is set in ruler frame, including fixed shaft sleeve, fixed ratchet wheel, guide pin fixed seat, guide pin and adjusting assembly.In the utility model, through the mutual abutment transmission structure of "force compression spring-movable ratchet wheel-fixed ratchet wheel", adjusting handle can be linked in the thread of adjusting handle when rotating, and drive measuring rod whole to slide in ruler frame, spring elasticity is converted into the measurement force of measuring rod, the precompression of force compression spring directly determines the frictional force between fixed ratchet wheel and movable ratchet wheel, and then control the contact force of measuring rod and workpiece;User can change the compression of force compression spring by adjusting threaded rod, adapt to the measurement demand of different material workpieces such as soft, hard and the like.
