Description
Technical Field
[0001] This invention belongs to the field of balancing and adjusting technology, specifically relating to a servo valve swing plate balancing and adjusting device. Background Technology
[0002] The servo valve is a crucial component of the servo motor. When powered on, its armature magnet drives the valve's vane to swing left and right, thus rotating the shaft. The range of the servo valve vane's swing determines the range of motion of the servo motor's actuator rod. Therefore, ensuring the servo valve vane's swing balance is a critical step in servo motor assembly. Existing testing methods suffer from low accuracy, significant errors, and frequent need for rework and readjustment. Summary of the Invention
[0003] The purpose of this invention is to provide a servo valve swing plate swing position balancing and debugging device, which can realize the swing range debugging of the servo valve swing plate with high debugging accuracy and high working efficiency.
[0004] This invention provides a technical solution for a servo valve swing vane oscillation position balancing and adjustment device:
[0005] A servo valve fixing assembly 1 and an angle measuring assembly 2 are installed on the base plate 3. The servo valve fixing assembly 1 is used to fasten and support the servo valve 4. The angle measuring assembly 2 includes an angle sensor 13, which measures the swing position of the servo valve 4's swing plate in real time and adjusts the swing range of the servo valve 4's swing plate according to the voltage value fed back by the angle sensor 13, thereby achieving the left and right swing balance of the servo valve 4's swing plate.
[0006] Furthermore, the servo valve fixing assembly 1 includes a support column 5, a fixing bracket 6, a fixing side plate 7, a fixing handle 8, a support screw 9, a tension spring 10, and a cylindrical pin 11;
[0007] The support column 5 is connected to the fixing frame 6 by screws; the rotation axis of the servo valve 4 is coaxial with the rotation axis of the angle measuring component 2.
[0008] A fixed side plate 7 is installed on each of the left and right sides of the fixed frame 6 to form an inner cavity for placing the servo valve 4;
[0009] The fixed handle 8 is connected to the fixed side plate 7 via a cylindrical pin 11. The cylindrical pin 11 is interference-fitted with the mounting hole of the fixed handle 8, and the cylindrical pin 11 is clearance-fitted with the mounting hole of the fixed side plate 7. The fixed handle 8 can rotate partially about the axis of the cylindrical pin 11. A tension spring 10 is provided between the fixed side plate 7 and the fixed handle 8 to reset the fixed handle 8 to its initial position. One end of the fixed handle 8 is provided with a threaded hole for installing a support screw 9. The support screw 9 is used to support the rebound force of the tension spring 10 and support the fixed handle 8 in a certain position.
[0010] Furthermore, a top pin 12 is provided at the position where the fixed side plate 7 contacts the support screw 9.
[0011] Furthermore, the angle measurement assembly 2 includes an angle sensor 13, a coupling 14, a support frame 15, an adapter plate 16, a slider 17, and a slide rail 18. The angle sensor 13 is mounted on the support frame 15 with screws, and its rotation axis is coaxial with the rotation axis of the servo valve 4. The coupling 14 is a flexible coupling that connects the rotation axis of the servo valve 4 and the rotation axis of the angle sensor 13 to the same axis, allowing them to rotate coaxially. The support frame 15 is mounted on the adapter plate 16 with screws. The adapter plate 16 is mounted on the slider 17 with screws. The slider 17 is mounted on the slide rail 18 and can slide freely.
[0012] After the support screw 9 is installed and fitted in the threaded hole of the fixed handle 8, it rotates. The fixed handle 8 is subjected to force through the thread and rotates locally around the axis of the cylindrical pin 11, thereby adjusting the position of the fixed handle 8 and fixing the servo valve 4.
[0013] The above technical solution measures the swing position of the servo valve vane in real time using an angle sensor, and adjusts the swing range of the servo valve vane according to the voltage value converted and fed back by the angle sensor, thereby achieving left and right swing balance of the servo valve vane. The servo valve vane swing position balance adjustment device has a simple structure, high adjustment accuracy, and improves work efficiency. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.
[0023] The servo valve swing plate swing position balancing adjustment device proposed in this invention includes a servo valve fixing component 1, an angle measuring component 2, and a base plate 3; the servo valve fixing component 1 is used to fasten and support the servo valve 4; the angle measuring component 2 includes an angle sensor 13, which measures the swing position of the servo valve 4 swing plate in real time, and controls the swing range of the swing plate by manually adjusting the limit screw on the servo valve 4 according to the voltage value converted and fed back by the angle sensor 13, so as to realize the left and right swing balance of the servo valve 4 swing plate.
[0024] In one embodiment of the present invention, a servo valve swing plate swing position balancing adjustment device is provided. The balancing adjustment device includes a servo valve fixing component 1, an angle measuring component 2 and a base plate 3. Figures 1(a) and (b) are schematic diagrams of the structure of the servo valve swing plate swing position balancing adjustment device provided in a specific embodiment of the present invention when it is not adjusted and when it is adjusted.
[0025] like Figure 2As shown, the servo valve fixing assembly 1 includes a support column 5, a fixing bracket 6, a fixing side plate 7, a fixing handle 8, a support screw 9, a tension spring 10, a cylindrical pin 11, and a top pin 12. The servo valve fixing assembly 1 is mainly used to secure the servo valve 4. The support column 5 is connected to the fixing bracket 6 by screws, coaxially aligning the rotation axis of the servo valve 4 with the rotation axis of the angle sensor 13. A fixing side plate 7 is installed on each side of the fixing bracket 6 by screws, forming an inner cavity for housing the servo valve 4. The fixing handle 8 is connected to the fixing side plate 7 by the cylindrical pin 11. The cylindrical pin 11 and the mounting hole of the fixing handle 8 are interference-fitted, while the mounting hole of the cylindrical pin 11 and the fixing side plate 7 are clearance-fitted. The fixing handle 8 can rotate around the axis of the cylindrical pin 11. The fixed handle 8 is partially rotated; a tension spring 10 is provided between the fixed side plate 7 and the fixed handle 8 to reset the fixed handle 8 to its initial position; a threaded hole is provided at one end of the fixed handle 8 for installing the support screw 9; the support screw 9 is used to support the rebound force of the tension spring 10 and support the fixed handle 8 in a certain position; a top pin 12 is provided at the position where the fixed side plate 7 contacts the support screw 9 to protect the outer surface of the fixed side plate 7 from being scratched by the support screw 9; the position of the fixed handle 8 in Figure 3(a) is the position before the servo valve 4 is installed and fixed, and Figure 3(b) is the position after the servo valve 4 is installed and fixed.
[0026] like Figure 4 As shown, the angle measuring assembly 2 includes an angle sensor 13, a coupling 14, a support frame 15, an adapter plate 16, a slider 17, and a slide rail 18. The angle sensor 13 is mounted on the support frame 15 with screws, and its rotation axis is coaxial with the rotation axis of the servo valve 4. The coupling 14 is a flexible coupling that connects the rotation axis of the servo valve 4 and the rotation axis of the angle sensor 13 to the same axis, allowing them to rotate coaxially. The support frame 15 is mounted on the adapter plate 16 with screws. The adapter plate 16 is mounted on the slider 17 with screws. The slider 17 is mounted on the slide rail 18 and can slide freely.
[0027] After the support screw 9 is installed and fitted in the threaded hole of the fixed handle 8, it rotates. The fixed handle 8 is subjected to force through the thread and rotates locally around the axis of the cylindrical pin 11, thereby adjusting the position of the fixed handle 8 and fixing the servo valve 4.
[0028] When slider 17 is manually pushed, it slides freely on slide rail 18. Angle sensor 13, which moves synchronously with slider 17, also moves accordingly. One end of coupling 14 is tightly connected to the rotating shaft of angle sensor 13. When the other end of coupling 14 moves to a position where it can be tightly connected to the rotating shaft of servo valve 4, slider 17 stops moving, and coupling 14 is tightly connected to the rotating shaft of servo valve 4, thus achieving coaxial connection between the rotating shaft of servo valve 4 and the rotating shaft of angle sensor 13. After connecting the cable and starting the software test, the swashplate of servo valve 4 begins to swing left and right. At the same time, the software interface can display the voltage value converted from the swing deflection angle measured in real time by angle sensor 13.
[0029] The above technical solution measures the swing position of the servo valve 4's swing plate in real time using the angle sensor 13, and adjusts the swing range of the servo valve 4's swing plate according to the voltage value converted and fed back by the angle sensor 13, thereby achieving the left and right swing balance of the servo valve 4's swing plate.
[0030] In summary, this embodiment of the invention achieves the secure fixing of the servo valve 4 through the cooperation of the fixing frame 6, fixing side plate 7, fixing handle 8, supporting screw 9, tension spring 10, cylindrical pin 11, and top pin 12; the movement of the angle sensor is achieved by the movement of the slider 17 on the slide rail 18; and the rotation shaft of the servo valve 4 is coaxially connected with the rotation shaft of the angle sensor 13 through the coupling 14. This debugging device has a simple structure, high testing accuracy, saves operation time, and improves work efficiency.
[0031] The above-described specific embodiments are limited to explaining and illustrating the technical solutions of the present invention, but do not constitute a limitation on the scope of protection of the claims. Those skilled in the art should understand that any new technical solutions obtained by making simple modifications or substitutions based on the technical solutions of the present invention fall within the scope of protection of the present invention.
