Problems solved by technology
[0002] Modular electric actuator is a kind of power mechanism of electric valve, which specially provides opening and closing torsion force for electric valve. When installing, choose intelligent type and non-intelligent type according to needs, and then transmit power through multi-edge rod plug connection. Accurate docking is required, and it is easy to deviate again during the overshoot of the docking, and the installation efficiency is low. Moreover, the length of the multi-edge rod is very high. If the multi-edge rod is too long, the connection flange and the flange on the valve will not be closed properly. Completely, the adaptation to the valve is relatively low, but the existing modular electric actuators cannot solve the above problems, and the installation efficiency can be further improved. Therefore, the present invention proposes a modular electric actuator

A modularized electric actuating mechanism provided by the present invention comprises an electric actuating mechanism body and a positioning mechanism, an output shaft of the electric actuating mechanism body is fixedly connected with a self-adaptive telescoping mechanism, and the self-adaptive telescoping mechanism comprises a fixed rod and a six-edge telescoping rod. A positioning power cylinder and a buffer rod are fixedly mounted at the bottom of the electric actuating mechanism body, and connecting flanges are fixedly mounted at the bottoms of the positioning power cylinder and the buffer rod. The modularized electric actuating mechanism is reasonable in design, after the positioning mechanism is pre-mounted, the positioning rod is matched with the positioning power cylinder, the effect of automatic positioning can be achieved, and the reliability of the electric actuating mechanism is improved. In addition, in the process that the positioning rod is inserted into the positioning power cylinder, the six-edge telescopic rod automatically stretches out for automatic insertion connection, and therefore the installation efficiency can be effectively improved.
Description
technical field [0001] The invention belongs to the technical field of actuator testing, in particular to a modular electric actuator. Background technique [0002] Modular electric actuator is a power mechanism of electric valve, which provides opening and closing torsion force for electric valve. During installation, intelligent and non-intelligent type are selected according to the needs, and then the power is transmitted through the multi-ribbed rod insertion. Accurate butt joints are required, and it is easy to deviate again during the butt overshoot, and the installation efficiency is low. In addition, the length of the polygonal rod is very high, and the long polygonal rod will cause the connection flange and the flange on the valve to be closed incorrectly. Completely, the adaptation to the valve is low, but the existing modular electric actuator cannot solve the above problems, and the installation efficiency can be further improved. Therefore, the present invention...
