Hydraulic buffering heavy-load electric cylinder based on disc spring compression and buffering control method

The invention relates to an electric cylinder, in particular to a hydraulic buffering heavy-load electric cylinder based on disc spring compression and a buffering control method.On the basis of the structure of an original electric cylinder, a buffering device with a disc spring set as a buffering piece is arranged between a nut and a push rod, and the design is small in occupied space and adjustable in buffering rigidity; a hydraulic buffer system is matched, when the loading force is suddenly increased, the influence of impact load on mechanical parts is remarkably reduced by adjusting the swing angle of the variable pump and the rotating speed of the servo motor, and the reliability and the service life of the electric cylinder are improved. 本发明涉及一种电动缸，特别涉及一种基于碟簧压缩的液压缓冲重载电动缸及缓冲控制方法，在原有电动缸的结构基础上，本发明在螺母与推杆之间设置以碟簧组为缓冲件的缓冲装置，该设计占用空间小且缓冲刚度可调，匹配液压缓冲系统，当负载力突然增大时，通过调整变量泵摆角和伺服电机转速，显著降低了冲击载荷对机械部件的影响，提高电动缸可靠性和使用寿命。
