The invention relates to the technical field of hoisting clamps, in particular to an annular workpiece auxiliary hoisting clamp which comprises a hoisting assembly, a hoisting pull rod capable of sliding in a reciprocating mode in the longitudinal direction is arranged in the center of the hoisting assembly, and when the hoisting pull rod slides in the longitudinal direction, a plurality of ejector rods can be synchronously driven to be synchronously pushed outwards or contracted inwards. A secondary push plate used for secondary ejection is further arranged on the outer side wall of the ejector rod, and an ejection block used for preventing the inner side wall of the workpiece body from being scratched is arranged at the tail end of the ejector rod. A rotating gear is driven by a motor to rotate, a gear ring rotates through an external thread, a secondary push plate is pushed out, a secondary clamping block gets close to the inner side wall of a workpiece body, when the secondary clamping block moves to an extrusion block to extrude the secondary clamping block, the secondary clamping block rotates, a damping block at one end of the secondary clamping block is pushed outwards, and the secondary clamping block moves to the inner side wall of the workpiece body. The purpose of secondary clamping is achieved, the falling risk caused by workpiece shaking or sliding is reduced, and therefore the safety of the hoisting process is improved, and the safety and stability of the hoisting process are guaranteed.

    本发明涉及吊装夹具技术领域,具体涉及一种环形工件辅助吊装夹具,包括吊装组件,吊装组件的中心位置处设置有可沿纵向往复滑动的吊装拉杆,吊装拉杆沿纵向滑动时可同步带动多个顶杆同步向外推出或向内收缩,顶杆的外侧壁还设有用于二次顶出的二次推板,顶杆的末端设置有用于避免划伤工件本体内侧壁的顶出块。本发明通过电机带动转动齿轮进行转动,使齿环通过外螺纹进行转动,将二次推板推出,二次夹紧块向工件本体的内侧壁进行靠近,当移动至挤压块挤压二次夹紧块时,使其发生转动,使二次夹紧块一端的阻尼块向外推出,实现二次夹紧的目的,减少因工件晃动或滑动而导致的脱落风险,从而提高吊装过程的安全性确保吊装过程的安全稳定。
