Abstract

The invention discloses a pneumatic-electric compound control actuator, which comprises a bottom plate, a casing, a pneumatic drive assembly and a motor drive assembly; the casing is a casing without a bottom cover, the bottom plate is fixed at the bottom of the casing, and There are round holes respectively; the pneumatic drive assembly is placed in the housing, one end of the motor drive assembly is placed in the housing, the other end passes through a round hole outside the housing, and one end of the pneumatic drive assembly protrudes from the other round hole of the housing. The other end is connected with the end of the motor drive assembly located in the casing. The invention can combine the advantages of pneumatic drive and motor drive to realize rapid and accurate displacement within a large stroke.

Description

technical field [0001] The invention relates to the field of pneumatic transmission and control engineering, in particular to a pneumatic-electric composite control actuator. Background technique [0002] Pneumatic technology has been rapidly developed and applied in the field of automation due to its advantages of safe use, no pollution, simple structure, convenient maintenance, reliable operation, low cost, and long life. [0003] The cylinder is an actuator that uses compressed air as the power source and converts the potential energy of the compressed air into mechanical energy. Its action forms include reciprocating motion and swing, and has the advantages of fast action speed, large output force-to-mass ratio, simple operation and low cost. . Traditional cylinder positioning relies on mechanical stop positioning or magnetic switch positioning, but these methods can only stop the cylinder at a fixed position, and the positioning accuracy is low, generally around 1mm. ...
