Punching clamp for U-shaped hanging ring

The utility model discloses a U-shaped hanging ring punching clamp which is installed on a punching machine and comprises a base, a fixed clamp installed on the base and a movable clamp symmetrical to the fixed clamp, and the movable clamp is far away from or close to the fixed clamp under the control of an air cylinder to clamp a U-shaped hanging ring. An upper clamping plate and a lower clamping plate are arranged between the fixed clamp and the movable clamp, synchronous clamping of the two ends of the U-shaped hanging ring is achieved, and synchronous punching of the two ends is achieved in cooperation with a punching machine. Synchronous punching of the two ends is achieved, the machining efficiency is improved, the coaxiality of holes in the two ends is guaranteed, and therefore the stability of follow-up hoisting is guaranteed. 本实用新型公开了一种U型吊环打孔夹具，安装在打孔机上，包括底座，安装在底座上的固定夹具，以及与固定夹具对称设置的活动夹具，所述活动夹具在气缸控制下远离或靠近固定夹具，形成对U型吊环的夹持，所述固定夹具与活动夹具之间具有上下两组夹板，实现对U型吊环两端的同步夹持，配合打孔机实现两端同步打孔。本实用新型实现两端同步打孔，不仅提升加工效率，同时确保两端孔的同
