Key-shaped executor

Abstract

The invention provides a key-shaped executor. The executor comprises a driving part, a transmission part and an execution part; the transmission part comprises a swing rod; the swing rod is provided with a rotating part; a first rod part and a second rod part are formed at the two radial ends of the rotating part of the swing rod in a length extending direction; the first rod part is provided witha first attraction and repulsion element; the driving part comprises a second attraction and repulsion element; the second attraction and repulsion element drives the first attraction and repulsion element to rotate along the rotating part; one or more execution parts are arranged on the second rod part; and a distance between the execution part and the rotating part is larger than and / or equal to and / or smaller than a distance between the first attraction and repulsion element and the rotating part. According to the executor, simultaneous output of multiple rods can be realized, and displacement amplification output or thrust amplification output can be carried out through the design of the position of the execution part on a shell.

Description

technical field [0001] The invention relates to the field of actuators, in particular to a key-shaped actuator. Background technique [0002] Actuators or drives are currently widely used in various technical fields, and common functions include excitation, regulation, transmission, etc. The patent document CN106971813A provides an electromagnetic actuator, including a housing, a coil placed inside the housing, and a terminal block installed on the housing and connected to the coil for supplying current. The two ends of the inner wall of the coil are respectively provided with a limit sleeve and an iron Core, one end of the iron core is provided with an actuator rod, the actuator rod is set on the limit sleeve, and the actuator rod is covered with a return spring, the setting of the return spring cooperates with the coil energization, so that the actuator rod can be pushed back and forth . The actuator provided in this technical document belongs to the relatively common st...

AI Technical Summary

Problems solved by technology

[0003] 1. Displacement benefits and frequency benefits cannot be achieved at the same time: that is to say, under the premise of a certain frequency, the output displacement of the actuator will be greatly limited;

[0004] 2. It is difficult to adjust the "gear position": according to the different use environments, there are different requirements for the stroke output or force output of the actuator, which requires a structure similar to the gear adjustment of a car. The existing actuators cannot realize the gear position. Adjustment, or an adjustment structure, but the structure is complicated and the volume is large;

[0005] 3. It is difficult to adjust the output direction of the actuator: the existing actuators are usually assembled in a single direction based on the relevant installation reference plane, and the output direction cannot be adjusted flexibly, which affects the scope of application
