1results about How to "Improve surface machining accuracy" patented technology

This invention discloses a cutting device and process for crankshaft machining, relating to the technical field of crankshaft machining equipment. It includes a support frame, a feeding trough, a guiding mechanism, a feeding mechanism, a tilting mechanism, a lifting mechanism, a CNC machining mechanism, a top-pressure rotation mechanism, a vibration stabilization mechanism, and a control system. The feeding trough, guiding mechanism, and feeding mechanism achieve automatic workpiece sorting and conveying; the tilting mechanism rotates the workpiece to a horizontal machining position; the lifting mechanism precisely lifts the workpiece to the machining position; the top-pressure rotation mechanism provides rotational power and works with the vibration stabilization mechanism to achieve automatic centering; the vibration stabilization mechanism detects vibration in real time through an accelerometer, and when vibration exceeds limits, drives an auxiliary pin assembly to press the crankshaft balance block, dynamically applying a damping force to counteract chatter. This invention solves the problems of large vibration, low centering accuracy, and insufficient automation in existing devices, significantly improving crankshaft machining accuracy and extending tool life, and is suitable for mass production of high-precision crankshafts.
