Description

Technical Field

[0001] This utility model relates to the field of actuator technology, specifically an adjustable electric actuator. Background Technology

[0002] Electric actuators are mechanisms used to control valves, which are mechanical devices that control the flow rate, direction, pressure, temperature, etc. of flowing fluid media. They are also basic components in pipeline systems. They can be operated manually or by handwheel, handle, or pedal, and can also change the pressure of the fluid media through control. Valves are widely used in various industries and daily life, and are indispensable devices for domestic water pipelines and industrial fluid pipelines.

[0003] Currently, the shafts used for connecting actuators include square shafts, single-key shafts, and double-key shafts, all of which are standard models. This solution only improves the connection of square shafts that produce rotary output. At present, the end face of the connection is a fixed square opening, which is not very applicable and cannot be used for square output shafts of various sizes, thus failing to meet customer needs. In response to the above problems, the inventor proposes an adjustable electric actuator to solve the above problems. Utility Model Content

[0004] To address the problem that the current connection end face is a fixed square opening, which has poor applicability and cannot be used for square output shafts of various sizes, the purpose of this utility model is to provide an adjustable electric actuator.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an adjustable electric actuator, comprising an actuator, the actuator comprising a coupling seat, a connecting shaft being embedded in the end face of the coupling seat, a connecting frame being provided on one side of the coupling seat, the axis of the connecting frame coinciding with the axis of the connecting shaft, stepped grooves being provided on both sides of the connecting frame, movable seats being provided at the four corners of the side wall of the connecting frame, a protruding plate being fixedly connected to the side wall of the movable seat, a fastening bolt being inserted through the side wall of the protruding plate, the head of the fastening bolt corresponding to and engaging with the large groove of the stepped groove, the shank of the fastening bolt corresponding to and engaging with the small groove of the stepped groove, and a clamping plate being detachably provided on the inner side wall of the movable seat.

[0006] Preferably, a fixing plate is fixedly connected to the end face of the connecting frame, and the side of the fixing plate away from the connecting frame is fixedly connected to the end face of the connecting shaft. There are four fixing plates, and the four fixing plates are arranged in an array around the axis of the connecting shaft. The fixing plates are offset from the stepped groove, and the connecting frame is fixedly installed to the connecting shaft through the fixing plates. Figure 2As shown, the connecting frame has a square cross-section and four fixing plates to reinforce the connection with the connecting shaft. When the connecting shaft rotates, the fixing plates can drive the connecting frame to rotate. The inner side wall of the movable seat is provided with a slot, and the outer side wall of the clamping plate is fixedly connected with a clamping plate. The clamping plate corresponds to and cooperates with the slot. The outer side wall of the movable seat is provided with a first pin hole, the bottom end of which extends into the slot. The top surface of the clamping plate is provided with a second pin hole, which corresponds to and has the same diameter as the first pin hole. A pin is provided on one side of the movable seat, which corresponds to and cooperates with the first and second pin holes. When the clamping plate is worn and needs to be replaced, pull the pin to disengage it from the first and second pin holes. Then, push the clamping plate to separate the clamping plate from the slot, so that the worn clamping plate can be removed. When installing a new clamping plate, the operation is reversed.

[0007] Preferably, the side wall of the convex plate is provided with a through hole, the shank of the fastening bolt passes through the through hole, and a nut is threaded onto the side wall of the fastening bolt. The width of the convex plate is larger than the small opening size of the stepped groove to prevent the convex plate from sinking into the stepped groove and thus failing to provide support. The end face of the connecting shaft is provided with a square hole. When the connecting shaft needs to be matched with the valve's opening and closing rod, the valve's opening and closing rod is inserted into the square hole. Through the interaction between the square hole and the opening and closing rod, when the connecting shaft rotates, the valve's opening and closing rod can be rotated. When facing valve opening and closing rods of different diameters, i.e., when the valve's opening and closing rod is matched with... When the square hole is not a good match, place the valve's opening / closing rod inside the bracket opening of the connecting frame, loosen the nut so that the fastening bolt can move within the stepped groove, then push the movable seat to move the clamping plate until the inner right-angled surface of the clamping plate contacts the right angle of the opening / closing rod, then tighten the nut in the opposite direction to limit and fix the convex plate, thereby limiting and fixing the movable seat, thus completing the limiting of the clamping plate. Similarly, adjust the position of the remaining clamping plates through the above steps to complete the limiting and fixing of the opening / closing rod, so that when the connecting shaft rotates, the fixed plate can drive the movable seat to rotate, and then the clamping plate can drive the opening / closing rod to rotate, thus completing the opening and closing of the valve.

[0008] Compared with the prior art, the advantages of this utility model are as follows: good applicability, the output end of the actuator can be adjusted to accommodate square output shafts of various sizes. When the valve's opening and closing rod corresponds to and matches the square hole of the connecting shaft, the valve's opening and closing rod can be directly inserted into the square hole for operation. When the valve's opening and closing rod does not match the square hole, the position of the movable seat can be adjusted so that the clamping plate clamps and fixes the valve's opening and closing rod, thereby improving applicability. It is suitable for square output shafts of various sizes and facilitates the replacement of the worn clamping plate. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0016] Example: Figure 1-4As shown, this utility model provides an adjustable electric actuator, including an actuator 1. The actuator 1 includes a coupling seat 2. A connecting shaft 3 is embedded in the end face of the coupling seat 2. A connecting frame 5 is provided on one side of the coupling seat 2. The axis of the connecting frame 5 coincides with the axis of the connecting shaft 3. Stepped grooves 7 are provided on both sides of the connecting frame 5. Movable seats 9 are provided at the four corners of the side wall of the connecting frame 5. A protruding plate 10 is fixedly connected to the side wall of the movable seat 9. Fastening bolts 8 are inserted through the side wall of the protruding plate 10. The head of the fastening bolt 8 corresponds to and cooperates with the large groove of the stepped groove 7. The rod of the fastening bolt 8 corresponds to and cooperates with the small groove of the stepped groove 7. A clamping plate 16 is detachably provided on the inner side wall of the movable seat 9.

[0017] A fixing plate 6 is fixedly connected to the end face of the connecting frame 5. The side of the fixing plate 6 away from the connecting frame 5 is fixedly connected to the end face of the connecting shaft 3. There are four fixing plates 6, and the four fixing plates 6 are arranged in an array with the axis of the connecting shaft 3 as the center. The fixing plates 6 are offset from the stepped groove 7.

[0018] By adopting the above technical solution, actuator 1 mainly consists of a motor, a reduction mechanism, a transmission mechanism, a position sensor, and a controller. The electric actuator receives electrical signals from the control system; these signals can be switching signals or analog signals. The controller drives the motor to rotate according to the received signals. The reduction mechanism and transmission mechanism convert the high-speed, low-torque output of the motor into a low-speed, high-torque output, causing the controlled equipment, such as a valve, to move to a designated position. Connecting shaft 3 is a transmission component in the transmission mechanism. Connecting frame 5 is fixedly installed to connecting shaft 3 via fixing plate 6. Figure 2 As shown, the cross-section of the connecting frame 5 is square, and there are four fixing plates 6 to reinforce the connection with the connecting shaft 3. When the connecting shaft 3 rotates, the fixing plates 6 can drive the connecting frame 5 to rotate.

[0019] The side wall of the protruding plate 10 is provided with a through hole 11, the shank of the fastening bolt 8 passes through the through hole 11, and the side wall of the fastening bolt 8 is threaded with a nut 12. The width of the protruding plate 10 is larger than the small groove size of the stepped groove 7.

[0020] By adopting the above technical solution, the width of the convex plate 10 is larger than the small groove size of the stepped groove 7 to prevent the convex plate 10 from sinking into the stepped groove 7 and thus failing to provide support. A square hole 4 is provided through the end face of the connecting shaft 3. When the connecting shaft 3 needs to be matched with the valve's opening / closing rod, the valve's opening / closing rod is inserted into the square hole 4. Through the interaction between the square hole 4 and the opening / closing rod, when the connecting shaft 3 rotates, the valve's opening / closing rod can rotate. When facing valve opening / closing rods of different diameters, i.e., when the valve's opening / closing rod does not match the square hole 4, the valve's opening / closing rod is placed in the bracket opening of the connecting frame 5, and the nut 12 is loosened to allow... The fastening bolt 8 can move within the stepped groove 7. Then, the movable seat 9 is pushed to move the clamping plate 16 until the inner right-angled surface of the clamping plate 16 contacts the right angle of the opening and closing rod. The nut 12 is then tightened in the opposite direction to limit and fix the protrusion 10, thereby limiting and fixing the movable seat 9, thus completing the limitation of the clamping plate 16. Similarly, the positions of the remaining clamping plates 16 are adjusted through the above steps to complete the limitation and fixing of the opening and closing rod, so that when the connecting shaft 3 rotates, the fixed plate 6 can drive the movable seat 9 to rotate, and then the clamping plate 16 can drive the opening and closing rod to rotate, thereby completing the opening and closing of the valve.

[0021] The inner side wall of the movable seat 9 is provided with a slot 13, and the outer side wall of the clamping plate 16 is fixedly connected with a clamping plate 17. The clamping plate 17 corresponds to and cooperates with the slot 13. The outer side wall of the movable seat 9 is provided with a first pin hole 14, the bottom end of which extends into the slot 13. The top surface of the clamping plate 17 is provided with a second pin hole 18, which corresponds to and has the same diameter as the first pin hole 14. A pin rod 15 is provided on one side of the movable seat 9, which corresponds to and cooperates with the first pin hole 14 and the second pin hole 18.

[0022] By adopting the above technical solution, when the clamping plate 16 is worn and needs to be replaced, pull the pin 15 so that the pin 15 is disengaged from the first pin hole 14 and the second pin hole 18. Then, push the clamping plate 16 so that the clamping plate 17 is separated from the clamping groove 13, thereby removing the worn clamping plate 16. When installing the new clamping plate 16, the operation is reversed.

[0023] Working principle: When this utility model is in use, when the valve opening and closing rod is engaged with the square hole 4 of the connecting shaft 3, the valve opening and closing rod can be directly inserted into the square hole 4. Through the mutual cooperation between the square hole 4 and the opening and closing rod, when the connecting shaft 3 rotates, the valve opening and closing rod can be rotated.

[0024] When dealing with valve opening and closing rods of different diameters, i.e., when the valve opening and closing rod does not match the square hole 4, place the valve opening and closing rod in the bracket opening of the connecting frame 5, loosen the nut 12 so that the fastening bolt 8 can move in the stepped groove 7. Then, push the movable seat 9 to move the clamping plate 16 until the inner right angle surface of the clamping plate 16 contacts the right angle of the opening and closing rod. Tighten the nut 12 in the opposite direction to limit and fix the convex plate 10, thereby limiting and fixing the movable seat 9, thus completing the limitation of the clamping plate 16. Similarly, through the above steps, adjust the position of the remaining clamping plates 16 to complete the limitation and fixing of the opening and closing rod, so that when the connecting shaft 3 rotates, the fixed plate 6 can drive the movable seat 9 to rotate, and then the clamping plate 16 can drive the opening and closing rod to rotate, thereby completing the opening and closing of the valve.

[0025] When the clamping plate 16 becomes worn and needs to be replaced after long-term use, pull the pin 15 to disengage the pin 15 from the first pin hole 14 and the second pin hole 18. Then, push the clamping plate 16 to separate the clamping plate 17 from the clamping groove 13, so that the worn clamping plate 16 can be removed and replaced in reverse.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
