Three round jaw self-centering chuck

Turn the blue lever to clamp or release the orange workpiece by three eccentrics. Rotate the blue lever to clamp or release the orange workpiece via three eccentrics. The eccentrics rotate synchronously thanks to two parallelogram mechanisms (consisting of the green cranks and yellow connecting rods). This type of simple chuck is suitable for applications that do not require high clamping force and high centering accuracy. STEP files of this video: https://www.mediafire.com/file/rgz28pch8ym...
