Description

Technical Field

[0001] This utility model relates to the field of electric actuators, and in particular to an electric intelligent actuator that is easy to fix. Background Technology

[0002] An electric intelligent actuator is a device that can receive signals from a control system and convert them into mechanical motion. It is widely used in various industrial automation control systems to control the opening and closing and adjustment of equipment such as valves and dampers. It is usually composed of a motor, reducer, control circuit, position feedback device, etc., and has the characteristics of intelligence, high precision, and high reliability.

[0003] A search revealed Chinese Patent Publication No. CN215172622U, which discloses an easy-to-install electric valve actuator. By incorporating a fixing component, the force generated when a spring deforms under stress acts on a locking block, causing the locking block to engage with the slot and fixing the movable block within the slot. This ensures the electric actuator body is stably fixed to the valve body, facilitating installation, reducing installation difficulty for workers, and improving work efficiency.

[0004] In the above technical solutions, the springs and locking blocks in the fixing components are used to achieve stable installation of the actuator. However, in restricted or complex environments, brackets or supports are needed to install the actuator and then connect it to the driven equipment. When installing the actuator, it is impossible to adapt to the environment and switch the orientation and angle, which reduces the flexibility of installation. Therefore, an electric intelligent actuator that is easy to fix is ​​proposed to solve the above problems. Utility Model Content

The top of the support base 11 is provided with a rotating groove 12 and a moving groove 13. The inner wall of the moving groove 13 is slidably connected to an elastic element 15. The elastic element 15 is composed of a telescopic rod and a spring. The spring is set in the cavity of the telescopic rod. The piston end of the telescopic rod is fixedly connected to the spring. The elastic force of the spring allows the elastic element 15 to extend and retract while automatically resetting. The movable end of the elastic element 15 is fixedly connected to a limit rod 16. The outer wall of the elastic element 15 is fixedly connected to a pull rod 14. The surface of the positioning plate 4 is provided with a limit hole 17. The surface of the support base 11 is provided with an adjustment component.

[0033] Reference Figures 3-5The inner wall of the locking hole 5 is adapted to the outer wall of the locking rod 6. The locking rod 6 extends through the locking hole 5 to the outside of the support frame 2, providing a limit for the support frame 2. The end of the telescopic spring 7 away from the surface of the locking rod 6 is fixedly connected to the inner wall of the positioning plate 4. The end of the locking rod 6 away from the telescopic spring 7 passes through the positioning plate 4. The inner wall of the rotating groove 12 is rotatably connected to the fixed end of the telescopic support column 10. The rotating groove 12 allows the telescopic support column 10 to rotate. The inner wall of the limiting hole 17 is connected to the limiting rod 16. The outer wall is adapted to the support base 11, and the outer wall of the pull rod 14 is slidably connected to the inner wall of the support base 11. The pull rod 14 can control the position of the elastic element 15 inside the moving groove 13. The adjustment component includes an eccentric wheel 20. The top of the support base 11 is provided with a relief groove 18. The inner wall of the support base 11 is threaded with a screw 19. The screw 19 is located on the inner wall of the relief groove 18. One end of the screw 19 located inside the relief groove 18 is fixedly connected to the eccentric wheel 20.

[0034] Reference Figure 3 The surface of the support frame 2 is provided with a straight slot 21, the center point of the straight slot 21 is aligned with the center point of the card hole 5. The inner wall of the card rod 6 is threaded with a lead screw 22, which is located at the end of the card rod 6 away from the telescopic spring 7. The end of the lead screw 22 is fixedly connected to a magnetic plate 24. The outer surface of the support frame 2 is fixedly connected with a magnetic block 23. The side wall of the magnetic block 23 is magnetically connected to the side wall of the magnetic plate 24. There are four sets of magnetic blocks 23, and the four sets of magnetic blocks 23 are arranged in pairs with each set of straight slots 21 in a cross shape. The shape of the straight slot 21 is the same as the shape of the magnetic plate 24, and the area of ​​the straight slot 21 is slightly larger than the area of ​​the magnetic plate 24, so that the magnetic plate 24 can pass through the straight slot 21 from the inside of the support frame 2.

[0035] Working principle: When installing the actuator body 1, align the positioning slot 3 with the rectangular protrusion of the positioning plate 4 and insert it. As the support frame 2 gradually descends and approaches the positioning plate 4, the locking rod 6 will be pushed into the cavity of the positioning plate 4 by the pressure of the support frame 2. At this time, the telescopic spring 7 will gradually stretch. After the support frame 2 is fixed on the positioning plate 4, the elasticity of the telescopic spring 7 will return, allowing the locking rod 6 to pass through the locking hole 5. At this time, a rotational force is applied to the magnetic plate 24, and the lead screw 22 will be screwed into the end of the locking rod 6 until the magnetic plate 24 and the two pairs of magnetic blocks 23 are in a close contact state. Through the magnetic attraction between the magnetic plate 24 and the magnetic blocks 23, the support frame is... 2. After the actuator body 1 is installed, when it is necessary to change its orientation, manually apply downward force to the limit rod 16. The limit rod 16 compresses the elastic element 15, and at the same time, the limit rod 16 disengages from the corresponding limit hole 17. Then, pull the elastic element 15 outward through the pull rod 14, causing the limit rod 16 to slide inside the moving groove 13, away from the limit hole 17. At this time, rotate the positioning plate 4. The positioning plate 4 drives the telescopic support column 10 to rotate inside the rotating groove 12, adjusting the orientation of the actuator body 1. After the orientation is changed, the limit holes 17 on both diagonals and the moving groove 1 are locked. After the position is horizontal, push the pull rod 14 to move the elastic element 15 inside the moving groove 13. When the limiting rod 16 is aligned with the corresponding limiting hole 17, the elastic element 15 loses its elasticity and automatically resets, allowing the limiting rod 16 to be inserted into the limiting hole 17 for positioning. Finally, if the installation position requires a certain degree of tilt, repeat the above steps to disengage the two sets of limiting rods 16 from the limiting hole 17. Manually rotate the screw 19 in the forward or reverse direction. As the screw 19 rotates in or out of the clearance groove 18, it drives the eccentric wheel 20 to rotate. The eccentric wheel 20 can press against the bottom of the positioning plate 4. At this time, the I-beam 9 can slide a certain distance inside the T-slot 8, causing one end of the positioning plate 4 to tilt up and the other end to drop. Since the screw 19 is threadedly connected to the inner wall of the support base 11, it can provide a limit to the eccentric wheel 20 after it rotates. By rotating the eccentric wheel 20 to the dead point position, a physical lock is formed, allowing the actuator body 1 to be installed in an inclined position. This provides greater flexibility for the installation of the actuator body 1, ensuring that the actuator body 1 can be accurately installed in the required position. This allows the actuator body 1 to find a suitable installation position and angle in various complex environments, improving the versatility and applicability of the equipment.
