The invention relates to the technical field of profile steel clamps, and particularly discloses a self-adaptive multi-connecting-rod mechanism clamp which comprises a clamp frame, two sets of electric push rods, a driving connecting rod, a synchronous connecting rod and clamping arms, the whole clamp frame is of a strip-shaped structure, and the two sets of electric push rods are symmetrically fixed to the upper portion of the clamp frame; the driving directions of the two electric push rods face the two ends of the clamp frame correspondingly. A plurality of sets of clamping arms are rotationally installed at the two ends of the clamp frame through hinged shafts correspondingly, and the clamping arms are symmetrically arranged on the two sides of the clamp frame. The clamping arms located at the same end and on the same side of the clamp frame are connected through a hinged shaft and a synchronous connecting rod, and the middle position of the synchronous connecting rod is connected with the end of a driving connecting rod. The two groups of driving connecting rods on the two sides of the same end of the clamp frame are connected through a hinged shaft and are connected to the output end of the electric push rod; linear motion of the electric push rod is converted into rotation of the clamp arm, opening and closing of a jaw of the clamp arm are achieved, profile steel is clamped and released, and efficiency and stability are achieved.
本发明涉及型钢夹具技术领域,具体公开了一种自适应多连杆机构夹具,包括夹具架、电动推杆、驱动连杆、同步连杆以及夹臂,所述夹具架整体呈条形结构,所述电动推杆设置有两组,对称固定在夹具架上部,且两组电动推杆的驱动方向分别朝着夹具架两端;所述夹具架两端分别通过铰轴转动安装有若干组夹臂,且夹臂对称设置在夹具架两侧;处于夹具架同一端且同一侧的夹臂之间通过铰轴与同步连杆相连,所述同步连杆的中间位置与驱动连杆的端部相连;处于夹具架同一端两侧的两组驱动连杆通过铰轴相连,并连接在电动推杆的输出端上;本发明通过将电动推杆的直线运动转化为夹具臂转动,实现夹具臂钳口的开合,来夹紧和放开型钢,高效稳定。
