【摘要】 介绍了单缸双活塞的铰杆增力机构、铰杆-杠杆增力机构的夹紧装置。由于铰杆、铰杆-杠杆机械增力机构具有力放大效果明显的优点,单缸双活塞具有结构紧凑、刚性好的优点,两者组合的液压夹紧装置可以应用在一些大型机械夹具上,如用绿色动力源——气源来代替液压油,该气压夹紧装置是一种绿色环保无污染的夹具。更多还原

【Abstract】 The paper introduces the clamping device of toggle and toggle- lever force amplifier based on single hydraulic cylinder double piston. As the toggle and toggle- lever mechanical force amplifier has the advantage of force magnifying,single hydraulic cylinder double piston has the advantages of compact structure,good rigidity,the hydraulic clamping device of the combination of the two can be applied in some large mechanical fixtures. If the green power sources of gas replace the hydraulic oil,the pneumatic clamping device is a fixture of green environmental protection without pollution.更多还原
