Description

Technical Field

[0001] The utility model relates to the technical field of testing devices for electric actuators, in particular to a functional testing platform for electric actuators. Background Art

[0002] As we all know, electric actuators refer to machines that use electricity as the main energy source to drive valves. Since they are precision electrical components, they are generally required to have certain explosion-proof and protection levels (waterproof and dustproof). According to the applicable working conditions, they are divided into explosion-proof and ordinary types. According to the actuator action mode, they are divided into switch type and regulating type. Multi-turn actuators are suitable for regulating valves, gate valves, stop valves and other valves that require multiple rotations of the valve stem to open and close, or drive butterfly valves, ball valves, plug valves and other partial-turn valves through worm gear drives. Part-turn actuators are generally used for butterfly valves, ball valves, plug valves and other valves that only need to rotate 90 degrees to open and close. The drive shaft of the straight-through actuator is in the same direction as the valve stem, and can be directly connected or with an additional connecting shaft.

[0003] After the electric actuator is produced, a test bench is needed to detect whether the function of the electric actuator is normal. The existing test bench is usually directly assembled on the valve body for control detection. However, if the line connection during the assembly process is incorrectly connected due to human operation, the electric actuator will not be able to operate normally, resulting in the situation where the personnel misjudge the electric actuator as a defective product. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

A splicing mechanism is provided between the installation grooves, an electric actuator body 9 is provided on the installation groove, a fastening box 10 is provided on the other side of the installation plate 5, a fastening hole is provided between one end of the fastening box 10 and the installation groove, a fastening column 11 is provided on the fastening hole, an oblique groove is provided on the top of one end of the fastening column 11, a fastening groove is provided inside the fastening box 10, the fastening groove is connected to the fastening hole, a fastening plate 12 is provided between the fastening groove and the fastening column 11, and a fastening plate 12 is provided between the fastening plate 12 and the fastening groove An elastic component 13 is provided, and a locking mechanism is provided between the fastening plate 12 and the fastening groove. In this embodiment, this structure places the electric actuator body 9 to be tested in the installation groove. During the placement process, the oblique groove opened at the top of one end of the fastening column 11 is squeezed by the electric actuator body 9 to make the fastening column 11 move in the fastening hole, and one end of the fastening column 11 leaves the installation groove. The electric actuator body 9 is placed in the installation groove. At this time, the fastening column 11 supports the fastening plate 12 through the elastic component 13, so that one end of the fastening column 11 extends into the installation groove. The fastening column 11 is located above the electric actuator body 9 at this time, which can prevent the electric actuator body 9 from leaving the installation groove. The limit plate 8 can be assembled in the installation groove through the splicing mechanism, which has a limiting effect on the electric actuator body 9. Personnel can directly connect the line of the electric actuator body 9 with the controller 2 and the valve body 3 through the installation groove. The multiple line interfaces 7 on the extension plate 6 can facilitate line connection.
