Abstract

The invention relates to a manual operation and electric operation matching switching mechanism of an electric actuator. The mechanism comprises an output shaft; the upper end of the output shaft is coated with a hand wheel base fixedly connected with a hand wheel; the upper part of the output shaft is coated with a bearing; the bearing is coated with a bearing base; the middle part of the output shaft is coated with a shaft sleeve; the shaft sleeve is coated with a worm wheel; the output shaft between the bearing base and the worm wheel is coated with a slide block; three upper bosses extend at the upper end of the slide block in the vertical direction, and two lower bosses extend at the lower end in the vertical direction; through holes matched with the upper bosses are formed in the side wall of the bearing base; grooves matched with the upper bosses are formed in the lower end of the hand wheel base; groove holes matched with the lower bosses are formed in the upper end of the shaft sleeve; and a first spring is arranged between the bearing base and the slide block. The mechanism further comprises a cam part for driving the slide block to axially move. The manual operation and electric operation matching switching mechanism of the electric actuator, provided by the invention, is simple and reasonable in structure, low in machining cost and higher in bearing capacity.

Description

technical field [0001] The invention belongs to the technical field of electric actuators, and in particular relates to a manual and electric coordination switching mechanism of an electric actuator. Background technique [0002] Actuator is a commonly used mechatronic equipment in the field of automatic control, and it is the executive equipment in the three major components of automation instruments. In some dangerous occasions, it can reduce the labor intensity of personnel and reduce the injury to operators. According to the power type, it can be divided into pneumatic, hydraulic, electric, electro-hydraulic, etc. Among them, the electric actuator has the advantages of convenient and easy access to energy, fast transmission signal speed, and long signal transmission distance. It is convenient to cooperate, easy to operate, and simple to connect and install. The integrated design of the electric actuator is easier to program and control, reducing the maintenance workload...
