AI Technical Summary
In existing crankshaft connecting rod journal follower grinding equipment, the integral structure of the grinding wheel head results in large mass of moving parts and large inertial impact force, which affects machining accuracy and stability. Furthermore, it is difficult to balance stiffness improvement and dynamic response capability.
The grinding wheel head is split into a two-stage slide with reverse motion and a follower slide, and a mass matching balancing component is set up. The mass change caused by grinding wheel wear is dynamically compensated by the counterweight fluid, which weakens the high-frequency inertial force and improves the machining accuracy and stability.
By canceling each other out by inertial forces, the impact load on the guide rail, lead screw and drive motor of high-frequency reciprocating motion is reduced, which improves the machining accuracy and consistency of batch processing and reduces bed vibration.
