Problems solved by technology

The structure of the device has the advantages of strong versatility, integrated integration, and simple development process. It can carry large thrust, flexible movement, quick response, reliability and stability, and easy to use. It solves the size and weight of deceleration linear actuators. The problem of too large and low dynamic response, as well as the problems of direct-drive linear actuators such as large mechanism clearance, large cumulative error, and poor overall rigidity, can be widely used in the linear motion function requirements of linear actuator products

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.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of electric actuators, and in particular relates to an integrated general-purpose linear actuator and a manufacturing process thereof. Background technique [0002] A linear actuator is a mechatronic device that converts electrical energy into mechanical energy and can output linear reciprocating motion. It is an important industrial equipment widely used in the fields of national defense, aerospace, transportation, industrial and agricultural production, etc. Compared with the traditional pneumatic servo mechanism and hydraulic servo mechanism, the electric linear actuator has outstanding advantages such as high power density, fast dynamic response, high motion precision, compactness, lightness, and convenient operation, and has gradually become a mature and mainstream servo motion actuator. [0003] As an actuator for precise linear reciprocating motion, the linear actuator mainly...
