设计了一种二次正交铰杆增力机构与碟簧组合而成的机械增力压紧装置,描述了铰杆增力机构的组成及工作原理,构建了铰杆增力机构与碟簧组的相应数学模型。该自锁系统运用铰杆机构过临界点后的自锁与力放大功能,与碟簧的组合使用实现在不耗能的条件下,长时间安全可靠地保持作用力。具有夹紧力大、节能效果明显等特性。 A mechanical force-augmenting device composed of a quadratic orthogonal hinge force amplification mechanism and a disc spring is designed. The composition and working principle of the force amplification mechanism are described. The mechanism of the hinge force amplification and the disc spring The corresponding mathematical model of the group. The self-locking system uses the self-locking and force amplification function of the hinge mechanism after the critical point. The combined use of the self-locking system and the disc spring can keep the force safely and reliably for a long time under the condition of no energy consumption. With a clamping force, energy-saving effect and other characteristics.
