摘　　要：液压夹具用液压元件代替机械零件实现对工件的自动定位、支承与夹紧,能保证工件在规定位置上准确定位和牢固压紧,并通过浮动支承减少加工过程中的振动和变形,且能减轻劳动强度和提高加工效率,因此液压夹具稳定性是保证产品加工质量的关键。从液压夹具的工作原理、夹具设计、负载分析、液压缸、切削系统稳定性实验等方面来论述液压夹具的稳定性控制。Hydraulic components are used to replace mechanical parts on hydraulic fixtures to realize automatic positioning,support and clamping of workpieces,which can ensure accurate positioning and firm pressing of workpieces at specified positions.The floating support reduces vibration and deformation during processing,reduces labor intensity and improves processing efficiency.Therefore,the stability of hydraulic fixtures is the key to ensuring product processing quality.The stability control of hydraulic clamping is discussed from the aspects of the working principle of hydraulic fixture,fixture design,load analysis,hydraulic cylinder and stability experiment of cutting system.
