Clamp-type measuring device and measuring method

The invention discloses a clamp-type measuring device includes a clamp and an interval measuring module. The clamp includes a guiding rail and two holding arm. Each of holding arms includes a guide part, a connecting part, and a clamping part. The guide part is movably furnished on the guiding rail. Both ends of the connecting part are respectively connected to the guide part and the clamping part. The interval measuring module includes a first measuring element and a second measuring element. The first measuring element and the second measuring element are furnished on the two connecting parts respectively. The first measuring element and the second measuring element are slidable through the two guide parts respectively in order to measure an interval between the two clamping parts. 本发明公开一种测量夹持装置及测量方法。该测量夹持装置包含一夹具及一距离测量组。夹具包含一导引轨及二夹持臂。二夹持臂各包含一导引段、一衔接段及一夹持段，二衔接段的各相对二端分别连接导引段及夹持段，导引段可移动地设置于导引轨，二夹持段用以夹持加工件。距离测量组包含第一测量元件及第二测量元件。第一测量元件设置于其中一衔接段。第二测量元件设置于另一衔接段。其中，第一测量元件与第二测量元件分别可通过二导引段相对导引轨滑动，以令第一测量元件与第二测量元件互相靠近或远
