所述底座一侧折面与连接座一侧折面之间设有第一、第二弹簧垫片，底座 一侧折面内侧设有第三弹簧垫片， 每片弹簧垫片的卡勾插入底座与连接座的 卡槽中。
所述连接座外侧与底座内侧通孔外沿呈凸起状，并对凸起表面做特殊处理 增加其硬度与耐磨性能。
所述轴心位于底座内侧端面开设有螺紋通孔，螺丝分别与轴心位于底座内 侧端面螺紋连接。
所述轴心为冲压件。
本发明一种枢轴装置的工作原理是：
底座一侧折面与连接座一侧折面上分别设有通孔，底座一侧折面与连接座 一侧折面之间设有两片弹簧垫片， 底座一侧折面内侧设有一片弹簧垫片， 底 座一侧折面与连接座一侧折面上的通孔与三片弹簧垫片均同轴设置， 三片弹 簧垫片均设有卡勾， 分别插入底座与连接座的卡槽中， 防止弹簧垫片随着枢 轴的转动而一起转动。 轴心从外侧穿过底座一侧折面与连接座一侧折面上的 通孔以及弹簧垫片， 弹簧钢簧片插入轴心位于底座内侧的通槽， 轴心位于底 座内侧端面开设有螺紋通孔， 螺丝分别拧入螺紋孔内， 或者轴心位于底座内 侧端面为平面， 敲击轴心位于底座内侧端面， 使轴心发生一定的塑性形变， 利用压力使弹簧钢簧片发生弹性形变， 弹簧钢簧片的弹性回复力挤压弹簧垫 片， 使弹簧垫片与底座一侧折面以及连接座一侧折面产生摩擦力， 从而能使 底座与连接座在任何角度上定位。 将连接座外侧与底座内侧通孔外沿部分凸 起， 并对凸起表面做特殊处理增加其硬度与耐磨性能， 可以代替上述弹簧垫 片的功能。
本发明一种枢轴装置的积极效果是：
(1) 利用弹簧钢簧片替代传统的弹片组合， 成本低， 组装方便省时， 加工 后变形度小， 稳定性高。
(2) 轴心为冲压件， 节约材料， 降低成本。 附图说明
