摘　　要：针对目前常用的丝杆加力台虎钳工作效率低、夹持力小和劳动强度大等问题,提出1种集丝杆加压、双速柱塞泵增压、液压缸驱动夹紧的多重增压方式及抱合支承于一体的新型集成夹紧系统。分析了台虎钳的研究进展概况,论述了集成夹紧系统的工作原理、结构特点、相关参数的计算方法,并通过设计计算,得到两种液压台虎钳夹紧系统的工作参数。结果表明:新型台虎钳夹紧系统结构紧凑,增压比大,采用较小的手动力和较少的手柄转动数圈,即可实现对工件的夹持,夹紧力大且稳定可靠;手工推动活动钳身部分进行快速移动,工作效率远高于丝杠传动,使用方便快捷,特别适合工件尺寸范围大、大小工件调换频繁的场合。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.
