AI Technical Summary

Technical Problem

[0005]基于以上所述，本实用新型的目的在于提供一种非接触式定位冶具，以解决定位冶具夹紧工件的问题

Benefits of technology

[0022]本实用新型的有益效果为：通过将配合磁性块可旋转地安装于解锁组件上，使得解锁组件向夹紧组件方向前进时，带动配合磁性块同步靠近主磁性块，从而先实现两磁性块之间的磁吸预耦合，为后续传动建立可靠连接；磁耦合建立之后或同时，解锁组件作用于夹紧组件，解除对空转组件的夹紧，使其进入可旋转状态；随后配合磁性块旋转，带动主磁性块及工件同步转动。而在解锁组件退回过程中，磁吸力仍维持，可抑制工件因惯性或外力发生非预期旋转，直至夹紧组件完全复位夹紧空转组件。实现了“前进预吸合、解锁后传动、回程抑转”的协同控制：在前进过程中，磁吸预耦合提前建立可靠的扭矩传递路径，确保旋转启动时不丢转；解锁发生在磁耦合完成之后或同时，避免了夹紧组件未释放而发生空转；在退回过程中，磁力的维持可抑制工件产生的非预期旋转，保障夹紧复位时工件处于初始位置，有效提升了传动的可靠性、动作的可控性以及工件定位的重复精度，提高生产速度。
