AI Technical Summary
Technical Problem
The wedge block assembly in existing torque limiters is prone to problems such as reduced contact area, damage to the lubricating oil film, surface damage, and uneven force distribution during use.
Method used
Design a full-contact wedge assembly for ejector pins, employing a structure of multi-plane pins, multi-plane stops, multi-plane wedges, and multi-plane spacers to ensure surface contact between the wedge and the mating surface. The multi-plane design improves the contact area and lubrication effect, achieving uniform force distribution.
Benefits of technology
It improves the load-bearing capacity and service life of the wedge block assembly, reduces friction, improves lubrication, reduces errors and facilitates reset, and enhances the uniformity of force distribution.

Abstract
本发明公开了一种顶针用全面接触楔块组件，包括多平面销轴、多平面挡块、多平面楔块、多平面隔套；多平面销轴穿过多平面挡块和多平面隔套设置，且多平面隔套对多平面销轴向下限位；多平面楔块设置有多个，均匀分布在多平面挡块和多平面隔套之间，且与多平面销轴贴合。本发明楔块与配合组件均为面接触，大大提高承载能力；楔块内、外侧面加工成平面，易于控制配合斜面精度，接触面积稳定便于系列化测试；接触面积更大，改善楔块磨损，提高使用寿命；面接触改善润滑效果，减小摩擦力，降低误差，方便复位；导向结构使楔块分布均匀，进而受力均匀增加使用寿命。
