Electric servo execution device combined with oil cylinder for use

The utility model relates to the field of driving devices, in particular to an electric servo executive device combined with an oil cylinder for use, which comprises a moving part, a pulling sleeve, a worm gear and a lead screw fixedly mounted on a piston rod of the oil cylinder, the pulling sleeve and the worm gear are coaxially and fixedly mounted, the pulling sleeve and the lead screw are in threaded connection, and the pulling sleeve and the moving part are in running fit. A worm is arranged on the moving part and is meshed with the worm gear; and the motor is used for driving the worm to rotate. According to the scheme, the control difficulty of a hydraulic system is weakened, and control over micro-speed movement and pressure fine adjustment of the press sliding block is facilitated. 本实用新型涉及驱动装置领域，具体涉及一种与油缸复合使用的电动伺服执行装置，包括移动部件、拔套、蜗轮和固定安装在油缸的活塞杆上的丝杆，拔套和蜗轮同轴固定安装，拔套和丝杆螺纹连接，拔套和移动部件转动配合，移动部件上设有蜗杆，蜗杆和蜗轮啮合；还包括用于驱动蜗杆转动的电机。本方案弱化液压系统的控制难度，便于对压机滑块的微速移动和压力微调进行控制。
