The invention relates to the technical field of mechanical clamps, in particular to a constant-clamping-force building clamp which comprises a top seat, a sliding frame and a vertical plate, a clamping assembly is arranged on the vertical plate and comprises hydraulic cylinders, pistons, a push rod, a connecting rod, a ball shaft, a spherical cover, a clamping jaw and a second spring, and the multiple pistons are slidably connected into the multiple hydraulic cylinders correspondingly; the plurality of push rods are fixedly connected to the plurality of pistons respectively, the plurality of connecting rods are fixedly connected to the plurality of push rods respectively, the plurality of ball shafts are fixedly connected to the plurality of connecting rods respectively, the plurality of spherical covers are slidably connected to the plurality of ball shafts respectively, and the plurality of clamping jaws are fixedly connected to the plurality of spherical covers respectively; according to the building material clamping device, multiple sets of spherical covers and clamping jaws are arranged to clamp a building material at multiple points, so that the pressure and the pressure intensity between the single clamping jaw and the building material are reduced, and the clamping force between each set of clamping jaws on each spherical cover and the building material can approach to be consistent; therefore, the problem that the clamping forces between different clamping jaws and the building material are different is solved.
本发明涉及机械夹具技术领域,具体是一种夹持力恒定的建筑用夹具,包括顶座、滑架和竖板,竖板上设置有夹取组件,夹取组件包括液压缸、活塞、推杆、连杆、球轴、球形罩、夹爪和第二弹簧,多个活塞分别滑动连接于多个液压缸的内部,多个推杆分别固定连接于多个活塞上,多个连杆分别固定连接于多个推杆上,多个球轴分别固定连接于多个连杆上,多个球形罩分别滑动连接于多个球轴上,多个夹爪分别固定连接于多个球形罩上;本发明能够通过设置多组球形罩和夹爪以对建材进行多个点位的夹持,从而减少单个夹爪与建材之间的压力和压强,且每个球形罩上的每组夹爪与建材之间的夹持力都能够趋近于一致,从而避免不同的夹爪与建材之间夹持力不同的问题。
