Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, and more specifically, to an electric actuator installation and positioning device. Background Technology

[0002] An electric actuator is a drive device that provides linear or rotary motion. It utilizes a driving energy source and operates under the action of a control signal. The actuator uses liquid, gas, electricity, or other energy sources and converts them into driving force through a motor, cylinder, or other device. Its basic types include three driving methods: partial rotation, multi-rotation, and linear stroke. The main advantages of electric actuators are high stability and constant thrust applicable to the user, as well as strong anti-deviation capability, which makes the output thrust or torque basically constant and can effectively overcome the unbalanced force of the medium.

[0003] In actual use, installers need to overcome the weight of the electric actuator and make fine adjustments in three-dimensional space to ensure that the output shaft and valve stem are perfectly aligned. This process usually requires two people to work together or to repeatedly try with the help of tools, which is time-consuming and labor-intensive, reducing the installation efficiency of electric actuators and valves. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electric actuator installation and positioning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An electric actuator mounting and positioning device includes an electric actuator and a valve, a fixing ring fixedly connected to the outside of the valve and a base block at the bottom of the electric actuator, the valve stem being connected to the output shaft of the electric actuator, and a guide mechanism being provided between the fixing ring and the base block; the guide mechanism includes multiple positioning blocks on the top of the fixing ring, and the multiple positioning blocks are arranged in a circular array on the top of the fixing ring, and one side of the multiple positioning blocks is fixedly connected to the outside of the valve; two protrusions are fixedly connected to the outside of each of the multiple positioning blocks, and the top of each positioning block and protrusion has two inclined angles; multiple limiting blocks are fixedly connected to the bottom of the base block, and the multiple limiting blocks are arranged in a circular array at the bottom of the base block, the inner side of each limiting block has a groove, and the bottom end of each limiting block has a guide surface, the groove being inserted into the positioning block and the two protrusions, and bolts are threadedly connected to the inner sides of the limiting block and the positioning block; a positioning mechanism is provided between the electric actuator and the valve.

[0006] By adopting the above technical solution: the tilt angle of the top of the positioning block is used to tilt and guide the groove on the inner side of the limiting block, and then the guide surface at the bottom of the limiting block is used to guide the valve surface, so that the output shaft and valve stem of the electric actuator and the valve are accurately aligned.

[0007] As a further description of the above technical solution: the positioning mechanism includes two connecting frames that are fixedly connected between the electric actuator and the valve, and a plurality of the connecting frames are symmetrically arranged on the surfaces of the electric actuator and the valve. Each of the plurality of connecting frames has a slot on its opposite side, and two insertion holes are opened on the outer side of the connecting frame. A connecting block is engaged between the two connecting frames on both sides of the electric actuator and the valve. The outer side of the connecting block engages with the slot on the inner side of the connecting frame. A screw is threadedly connected to one side of the connecting block. A connecting plate is provided on the outer side of the screw. A plurality of pins are fixedly connected to one side of the connecting plate. The outer side of the pins passes through the insertion holes on the outer side of the connecting frame and the inner side of the connecting block, respectively.

[0008] By adopting the above technical solution: using two connecting blocks to snap and position the two connecting frames and slots on opposite sides of the electric actuator and valve, and then using connecting plates and multiple pins to insert the connecting frames and connecting blocks at multiple points, the installation and positioning of the electric actuator and valve are further stabilized.

[0009] The technical effects and advantages of this utility model are as follows: By setting a guiding mechanism, compared with the existing technology, the inclined angle of the end of the positioning block and the groove at the bottom of the limiting block are used to achieve mutual inclined guidance. The actuator only needs to be roughly placed in position. When the guide inclined surface begins to contact, it will automatically guide the actuator to the correct center position, so that the output end and valve stem of the electric actuator and valve can be quickly aligned, effectively simplifying the installation process and reducing the difficulty of installing electric actuators and valves. By setting up a positioning mechanism, compared with the existing technology, the interlocking cooperation of two connecting blocks and multiple connecting frames, combined with connecting plates and multiple pins, is used to achieve multi-point positioning of the connecting frames and connecting blocks, so that the electric actuator and valve are locked and positioned on both sides after installation, ensuring the stable connection of the electric actuator and valve.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The embodiments disclosed in this application are as follows: Figures 1-8 The electric actuator mounting and positioning device shown includes an electric actuator 1 and a valve 2, as well as a fixing ring 3 fixedly connected to the outside of the valve 2 and a bottom block 7 at the bottom of the electric actuator 1. The valve stem of the valve 2 is connected to the output shaft of the electric actuator 1. A guide mechanism is provided between the fixing ring 3 and the bottom block 7. The guide mechanism includes multiple positioning blocks 4 on the top of the fixing ring 3, and the multiple positioning blocks 4 are arranged in a circular array on the top of the fixing ring 3. One side of the multiple positioning blocks 4 is fixedly connected to the outside of the valve 2. Preferably, the outer side of the positioning blocks 4 is provided with threaded holes for bolt 10 threaded connection. Two protrusions 5 are fixedly connected to the outer side of each of the multiple positioning blocks 4. Each of the tops of the strip 5 has two inclined angles 6; the bottom of the base block 7 is fixedly connected to multiple limiting blocks 8, which are arranged in a circular array at the bottom of the base block 7. The inner side of the limiting block 8 has a groove 9, and the bottom end of the limiting block 8 has a guide surface 11. The groove 9 is inserted into the positioning block 4 and the two protruding strips 5. The inner sides of the limiting block 8 and the positioning block 4 are threaded with bolts 10; a positioning mechanism is provided between the electric actuator 1 and the valve 2. The two inclined angles 6 at the end of the positioning block 4 and the guide surface 11 at the bottom of the limiting block 8 are used to tilt and guide the groove 9 and the surface of the valve 2 respectively, so that the output shaft and valve stem of the electric actuator 1 and the valve 2 can be accurately aligned.

[0021] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the positioning mechanism includes two connecting brackets 12 fixedly connected between the electric actuator 1 and the valve 2, and multiple connecting brackets 12 are symmetrically arranged on the surfaces of the electric actuator 1 and the valve 2. Each connecting bracket 12 has a slot 13 on its opposite side, and two insertion holes are provided on the outer side of each connecting bracket 12. A connecting block 14 is engaged between the two connecting brackets 12 on both sides of the electric actuator 1 and the valve 2. The outer side of the connecting block 14 engages with the slot 13 on the inner side of the connecting bracket 12. Preferably, the inner side of the connecting block 14 has a thread for screw 17 threaded connection. A screw 17 is threadedly connected to one side of the connecting block 14. A connecting plate 15 is provided on the outside of the screw 17. Multiple pins 16 are fixedly connected to one side of the connecting plate 15. The outer side of the pins 16 passes through the insertion hole on the outside of the connecting frame 12 and the inside of the connecting block 14. The connecting plate 15 and the multiple pins 16 are used to perform multi-point insertion and positioning of the upper and lower ends of the two connecting frames 12 and the slot 13. Then, the screw 17 is used to connect the threaded hole on the inside of the connecting plate 15 and the connecting block 14, so that the two connecting blocks 14 can support and position the two ends of the electric actuator 1 and the valve 2.

[0022] The working principle of this utility model is as follows: When assembling the electric actuator 1 and the valve 2, the bottom block 7 and multiple limiting blocks 8 of the electric actuator 1 are first matched with the fixing ring 3 and multiple positioning blocks 4 at the top of the valve 2. The tilt angle 6 at the top of the multiple positioning blocks 4 is used to tilt and guide the groove 9 on the inner side of the limiting block 8. At the same time, the guide surface 11 at the bottom of the multiple limiting blocks 8 is tilted to expand the insertion angle, so that the multiple guide surfaces 11 can tilt and guide the top of the valve 2. The multiple positioning blocks 4 are matched with the two outer tilt angles 6 and the corresponding grooves 9, so that the multiple positioning blocks 4 at the top of the fixing ring 3 and the multiple limiting blocks 8 at the bottom of the bottom block 7 are engaged with each other, thus completing the initial connection of the electric actuator 1 and the valve 2. The output shaft at the bottom of the electric actuator 1 and the valve stem at the top of the valve 2 can be quickly aligned and connected. Then, multiple bolts 10 are inserted into the corresponding limit block 8 and positioning block 4 and threaded together to complete the connection between the output shaft and valve stem of the electric actuator 1 and the valve 2. At this time, the two connecting brackets 12 on opposite sides of the electric actuator 1 and valve 2 are aligned. Then, the two connecting blocks 14 are inserted into the two connecting brackets 12 and slots 13 at both ends of the electric actuator 1 and valve 2. The two connecting brackets 12 and slots 13 are used to maintain a stable connection with the upper and lower ends of the connecting blocks 14. Then, the two connecting plates 15 and the multiple pins 16 on one side are inserted into the inner side of the connecting brackets 12 and connecting blocks 14 in sequence, so that the two connecting brackets 12 and connecting blocks 14 are positioned by multiple insertion points. Then, the two screws 17 are inserted into the connecting plates 15 in sequence, and one end of the connecting plate 15 is rotated into the threaded hole on the inner side of the connecting block 14, so that the connecting plate 15 and the connecting block 14 are connected and limited, thereby completing the installation and positioning of the electric actuator 1 and valve 2.
