我厂企业标准《通用铣刨夹具》中的回转式螺丝虎钳是铣刨加工中广泛采用的夹具。过去曾因其操作费力(工件夹紧力一般约在3000公斤以上),强力铣削时夹紧工件不够牢靠,所以没有广泛应用。后试用气动或气动液压夹紧机构,因气源不稳定,且结构复杂,也未能推广。1976年底,我们从有关资料及工厂了解到液压增力虎钳的结构,于是我们同车间技术人员、工人一起进行了试验研究,将原回转式螺丝虎钳改装成液压增力虎钳——当旋转手柄螺
Our factory standard “universal milling fixture” in the rotary screw vise is widely used in milling processing fixture. In the past because of its laborious labor (workpiece clamping force is generally about 3000 kg), strong milling clamping workpiece is not solid enough, it is not widely used. After the pilot pneumatic or pneumatic hydraulic clamping mechanism, due to unstable gas source, and the complex structure, but also failed to promote. At the end of 1976, we learned about the structure of the hydraulic booster vise from the relevant information and the factory, and we conducted a pilot study with the workshop technicians and workers to convert the original rotary vise to the hydraulic booster - Rotate the handle screw
