Integrated universal linear actuator and manufacturing process thereof

Abstract

The invention provides an integrated universal linear actuator and a manufacturing process thereof. The linear actuator comprises a hollow motor, a transmission-action module, a displacement sensor, a mechanical-electric linkage locking device and a driving control system. The hollow motor is connected with the transmission-action module through a lead screw and nut pair so that the rotating motion of the hollow motor can be directly converted into the linear reciprocating motion of the transmission-action module. The displacement sensor is connected with the transmission-action module through the mechanical-electric linkage locking device and used for outputting a position feedback signal of the transmission-action module to the driving control system. The driving control system is electrically connected with the hollow motor and used for sending a driving instruction signal to the hollow motor, controlling the hollow motor to operate and receiving the position feedback signal output by the displacement sensor so as to judge the current displacement of the transmission-action module, regulate and control the linkage motion of the hollow motor and the transmission-action module and enable the linear actuator to output continuous linear reciprocating motion.
