The invention provides a small hydraulic locking device. The small hydraulic locking device comprises a mounting plate and a hook; two sets of fixing plates are arranged on the right side of the mounting plate in an aligned mode, and fixing shafts are arranged in the middles of the upper ends of the fixing plates. The hook is rotationally connected with the fixed shaft, and the lower end of the hook is fixedly connected with a telescopic part of a hydraulic cylinder; and a limiting adjusting jackscrew is arranged at the upper end of the hydraulic cylinder, and the two ends of the limiting adjusting jackscrew penetrate through the outer sides of the fixing plates and are fixed through fixing pins. According to the device, torsional springs are arranged on the outer surfaces of the fixing shafts, and the ends of the torsional springs are arranged at the upper end of the limiting adjusting jackscrew, so that in the part transportation process, connection between the hook and the handle ismore compact, parts are better fixed, and the stability is improved; meanwhile, when the telescopic part of the hydraulic cylinder stretches forwards, the hook moves upwards; the handle is separatedfrom the hook, the torsional springs store forces in the process, and when the telescopic part of the hydraulic cylinder shrinks, the hook can automatically reset under the action of the elastic forces of the torsional springs.
本发明提供一种小型液压锁紧装置,包括安装板和挂钩;所述安装板右侧对位设有两组固定板,且固定板上端中间位置设有固定轴;所述挂钩与固定轴转动连接,且挂钩下端与液压缸伸缩部位固定连接;所述液压缸的上端设有限位调节顶丝,且限位调节顶丝两端穿过固定板外侧并通过固定销固定。本发明中,通过固定轴的外表面设有扭簧,且扭簧的端部位于限位调节顶丝上端的设置,使得在零件运输过程中,让挂钩与把手的连接更加紧凑,从而实现对零件更好的固定,增加了稳定性,同时,当液压缸伸缩部位向前伸展时,挂钩向上运动,把手与挂钩脱离接触,在这个过程中扭簧蓄力,当液压缸伸缩部位收缩时,在扭簧弹力作用下可以让挂钩自动复位。
