Description

Technical Field

[0001] The utility model relates to the technical field of actuators, in particular to a modular multi-position actuator. Background Art

[0002] The actuator is an indispensable and important component in the automatic control system. Its function is to receive the control signal sent by the controller and change the size of the controlled medium, so as to maintain the controlled variable at the required value or within a certain range. The actuator can be divided into three categories according to its energy form: pneumatic, hydraulic and electric.

[0003] However, when the existing modular multi-position actuator is used, the actuator body is usually exposed to the external environment. When external objects move, they are likely to touch the actuator body. The impact force generated by the touch is likely to damage the internal components of the actuator body, which has a certain impact on the service life of the actuator body. Therefore, a modular multi-position actuator is provided. Utility Model Content

[0004] The main purpose of the utility model is to provide a modular multi-position actuator. The utility model solves the problem that it is inconvenient to protect and repair the actuator body when the existing modular multi-position actuator is in use by arranging an outer frame, a support plate, a positioning rod, a through hole A, a through hole B, a shell A, a shell B, a threaded block and a bidirectional threaded screw.

[0006] By adopting the above technical solution, first place the shell B outside the actuator body, then push the shell A to move, then the support plate on one side of the shell A moves in the groove opened on the surface of the shell B, then the shell A and the shell B move to the outside of the actuator body, then rotate the drive rod on the outer frame, the drive rod drives the bidirectional threaded screw to rotate, the threaded block outside the bidirectional threaded screw drives the fixed rod to move, the positioning rod outside the fixed rod enters the through hole A opened on the surface of the shell B, then the positioning rod enters the through hole B opened on the surface of the support plate, the threaded block outside the bidirectional threaded screw, the fixed rod and the positioning rod are all provided with two groups, and the support plate connected to the shell A is provided with two groups, so that it is convenient to fix the shell A and the shell B outside the actuator body, so as to facilitate the protection of the actuator body;

[0007] When the actuator body fails, the driving rod on the outer frame is rotated, and then the driving rod drives the bidirectional threaded screw to rotate, and the threaded block outside the bidirectional threaded screw drives the positioning rod on the fixed rod to move, and then the positioning rod is moved out of the through hole B opened on the support plate surface, and then the positioning rod is moved out of the through hole A opened on the surface of the shell B, and then the shell A is pulled to move, and then the support plate on one side of the shell A is moved out of the shell B, and then the shell A is separated from the actuator body, so that the actuator body is exposed to the external environment, so as to facilitate the maintenance of the actuator body;

However, the fans in shell A and shell B accelerate the air flow speed on the surface of the actuator body. Then the heat on the actuator body is discharged outward through the fixing holes opened on the surface of shell A and shell B, thereby facilitating the heat dissipation of the actuator body.

[0009] Specifically, a connection plate in contact with the shell A is welded on the outer side of the shell B, and a rubber pad for improving the sealing performance of the shell A is fixed with screws on the inner side of the connection plate.

[0015] Specifically, a support rod is welded inside the outer frame, and a support block connected to the fixed rod is slidably connected outside the support rod.

[0016] By adopting the above technical solution, when the fixed rod drives the positioning rod to move, the support block outside the fixed rod slides outside the support rod, thereby improving the stability of the movement of the positioning rod outside the fixed rod.
