详细分析了克林贝格三维线性测头(K3D)结构具有三个轴向运动质量、偏转力和偏转刚度相等,且动态特性一致的结构特点,并对其三个方向的偏转结构、“共平面”结构以及主动测量结构着重进行了结构分析,其“共平面”结构极大地减小了在 XZ -平面的阿贝误差,并通过一对梯形双轴铰链杆将沿探针轴向的偏转位移转移到测头后部进行测量,设计非常巧妙,克服了三层嵌套式结构三轴向偏转运动质量不相等的缺点,另外在直角双轴杆处设计了一个可分离的主动测量机构使得测头具备主动向任意方向偏转测量的主动测量功能。
詳細分析瞭剋林貝格三維線性測頭(K3D)結構具有三箇軸嚮運動質量、偏轉力和偏轉剛度相等,且動態特性一緻的結構特點,併對其三箇方嚮的偏轉結構、“共平麵”結構以及主動測量結構著重進行瞭結構分析,其“共平麵”結構極大地減小瞭在 XZ -平麵的阿貝誤差,併通過一對梯形雙軸鉸鏈桿將沿探針軸嚮的偏轉位移轉移到測頭後部進行測量,設計非常巧妙,剋服瞭三層嵌套式結構三軸嚮偏轉運動質量不相等的缺點,另外在直角雙軸桿處設計瞭一箇可分離的主動測量機構使得測頭具備主動嚮任意方嚮偏轉測量的主動測量功能。

This paper analyzes Klingelnberg K3D probe system architecture has three axially moving mass,equal to the deflection force and a deflection stiffness and dynamic characteristics consistent with the structural characteristics,and the deflection of the three directions of its body,"coplanar"mechanism,and active measuring mechanism for a structural analysis focused on,the "coplanar"institutional greatly reduces the Abbe error in the XZ -plane,and passed through a biaxial hinge trapezoidal lever deflection along the axial displacement of the probe transferred to the rear of the probe probe design is very clever,to overcome the disadvantage of the three nested structure that three axial deflection moving mass does not equal,another in the cartesian axis rod and designed a detachable body makes active measurement probe deflected in any direction with the initiative to measure active measurement function.
