Abstract: Aiming at the problems of low working efficiency, small clamping force, and high labor intensity of the commonly used screw rod booster vise, a new clamping system is proposed, integrating screw pressure, two-speed plunger pump pressure, hydraulic cylinder-driven clamping, and embracing support. In this paper, the research progress of bench vise is analyzed. Then, the working principle, structural characteristics and calculation method of relevant parameters of the integrated clamping system are discussed. Finally, the working parameters of two hydraulic bench vise clamping systems are obtained through design calculation. The results show that the new vise clamping system has a more compact structure, larger pressurization ratio, less manual force, and fewer handle turns, making the clamping of the workpiece have enough clamping force, stable and reliable. Manual pushing the movable clamp body part for rapid movement, work efficiency is much higher than the screw drive. It is especially suitable for occasions with a large workpiece size range and frequent replacement of large and small workpieces.
