Clamp device for alignment plate for optical part machining

A clamp device for an optical part machining sample plate comprises a supporting shell (1) used for containing the optical part machining sample plate and a jacking screw rod (3) arranged on the supporting shell (1) and used for clamping the optical part machining sample plate, surrounding supporting of the optical part machining sample plate is achieved through the supporting shell (1), and the optical part machining sample plate is clamped through the jacking screw rod (3). At least three ends of the sample plate for optical part machining are folded and fixed through the jacking screws (3), and therefore the machining efficiency of the sample plate for optical part machining is improved. 一种用于光学零件加工对样板的夹具装置，包含有用于对光学零件加工对样板进行容纳的支撑壳(1)、设置在支撑壳(1)上并且用于对光学零件加工对样板进行夹紧的顶紧螺杆(3)，通过支撑壳(1)，实现了对光学零件加工对样板的环绕支撑，通过顶紧螺杆(3)，实现了对光学零件加工对样板的至少三个端头收拢固定，因此提高了光学零件加工对样板的加工效率。
