Description

Technical Field

[0001] This invention relates to the field of rudder deflection accuracy testing technology, and more specifically, to a highly integrated servo motor high-precision rudder deflection accuracy testing device and method. Background Technology

[0002] The pointer-type test is used to measure the deflection accuracy of highly integrated servos. The pointer is manually observed and the angle it indicates is recorded. Data is first recorded on draft paper, and if the test result is satisfactory, it is recorded on a log sheet. If it fails, adjustments are made and the test is repeated. Each product requires at least two tests. Sufficient observation time must be allocated during testing to allow for the personnel observing the pointer, which increases the testing time. Completing the deflection accuracy test for one product takes a long time and is inefficient. Since the highly integrated servo has a 1-to-4 structure, the deflection accuracy of four servo positions needs to be observed simultaneously. This requires five people to complete the test: one to perform the test and four to observe the pointer and record data, resulting in high manpower consumption. The dial's high precision is limited to 0.5°, leading to low test accuracy. Furthermore, the deflection accuracy requirement for highly integrated servos is 0.05°. Using a dial-type test, the last decimal place is an estimated reading, which can result in significant errors depending on the operator.

[0003] The method of manually observing and recording the rudder deflection accuracy angle indicated by the pointer of the high-integration servo motor, and then recording the final qualified result in the assembly and adjustment logbook after the test is completed and the test result is qualified, has the following disadvantages:

[0004] High manpower requirements: Since highly integrated servos are all 1-to-4 structure, the servo deflection accuracy of 4 servo positions needs to be observed simultaneously. During testing, 5 people are required to complete the test of this project: 1 person is responsible for testing, and 4 people are responsible for observing the 4 servo position pointers and recording data, which results in high manpower requirements.

[0005] Low testing accuracy: The high precision of the scale on the dial is only 0.5°, resulting in low testing accuracy.

[0006] The test results have large errors: because the scale on the dial is only 0.5° with high precision, while the rudder deflection accuracy of a highly integrated servo motor is required to be 0.05°, the last decimal place of the rudder deflection accuracy test is estimated data when using a dial, and the estimation results of different operators have large errors.

[0007] Low testing efficiency: During testing, data must first be recorded on draft paper. If the test result is qualified, it is recorded on the record sheet. If it is unqualified, it is retested after debugging. Each product needs to be tested at least twice. In order to allow the personnel observing the pointer enough observation time, sufficient observation time needs to be reserved, which increases the testing time and ultimately leads to low efficiency of rudder deflection accuracy testing.

[0008] There is a risk of recording data errors and exceeding the limit: Due to the large amount of data, there is a risk of copying errors. If an error is made, the assembly and adjustment record sheet must be replaced and the data rewritten. Summary of the Invention

[0009] The purpose of this invention is to provide a highly integrated servo motor high-precision servo deflection accuracy testing device, which can solve the problems of large manpower consumption, low testing accuracy, large test result error, low testing efficiency and easy error in copying that exist when using pointer-type servo deflection accuracy testing.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] On the one hand, this specification provides a high-precision servo deflection accuracy testing device for a highly integrated servo motor, including a drive shaft (5) and an adapter sleeve (8) assembled together, followed by the assembly of an inertia block (7) onto the adapter sleeve (8). The drive shaft (5), adapter sleeve (8), and inertia block (7) are adjusted to ensure that the parallelism between the inertia block (7) and the reference surface A on the drive shaft (5) meets the requirements. A pin (1) is driven in, and standard screws (10) are used to fasten the inertia block (7) and the drive shaft (5) together, ensuring that the inertia block (7) and the drive shaft (5) are aligned. The shaft (5) is positioned without moving. Then, drill a Φ8 pin hole and make a connecting pin (6). After connecting the drive shaft (5) and the adapter sleeve (8) with the connecting pin (6), put the flat washer (12) and spring washer (13) on the connecting pin (6) and tighten it with the nut (11). The tooling is designed with a clamp (3) to tighten the electronic angle gauge (4). It is tightened on the inertia block (7) by using standard screws (2). At the same time, a special screw (9) is designed to fasten the rudder deflection indicator tooling to the high-integration servo motor.

[0012] Based on the above technical solution, this specification can achieve the following technical effects:

[0013] The purpose of this invention is to design and manufacture a high-precision servo deflection accuracy testing device and method for highly integrated servos. This method improves the accuracy of servo deflection data acquisition by using an electronic angle meter. A dedicated servo deflection accuracy testing fixture is designed to support the electronic angle meter and is integrated with servo testing software. The servo deflection accuracy testing fixture transfers the test results of the highly integrated servo to the electronic angle meter for direct display. The servo testing software then reads the data from the electronic angle meter, achieving automatic data acquisition and saving for the highly integrated servo deflection accuracy test, and directly printing the test results. This reduces the time required for operators to read data during the high-precision servo deflection accuracy testing process for highly integrated servos. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and are not to a precise scale, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0024] It should be noted that, in order to clearly illustrate the content of this invention, several embodiments are provided to further explain different implementations of the invention. These embodiments are enumerated rather than exhaustive. Furthermore, for the sake of brevity, content mentioned in the preceding embodiments is often omitted in the following embodiments. Therefore, content not mentioned in the later embodiments can be referred to in the preceding embodiments.

[0025] Please refer to Figures 1 to 7One embodiment of this specification provides a high-precision servo deflection accuracy testing device for a highly integrated servo motor. The device includes assembling a drive shaft (5) and an adapter sleeve (8), then assembling an inertia block (7) onto the adapter sleeve (8). The drive shaft (5), adapter sleeve (8), and inertia block (7) are adjusted to ensure the parallelism between the inertia block (7) and the reference surface A on the drive shaft (5) meets the requirements. A pin (1) is driven in, and standard screws (10) are used to fasten the inertia block (7) to the drive shaft (5), ensuring that the inertia block (7) and the drive shaft (5) are aligned. The position of the drive shaft (5) does not move. Then, drill a Φ8 pin hole and make a connecting pin (6). After connecting the drive shaft (5) and the adapter sleeve (8) with the connecting pin (6), put the flat washer (12) and spring washer (13) on the connecting pin (6) and tighten it with the nut (11). The tooling is designed with a clamp (3) to tighten the electronic angle gauge (4). It is tightened on the inertia block (7) by using standard screws (2). At the same time, a special screw (9) is designed to connect and tighten the rudder deflection indicator tooling with the high-integration servo motor.

[0026] The purpose of this invention is to design and manufacture a high-precision servo deflection accuracy testing device and method for highly integrated servos. This method improves the accuracy of servo deflection data acquisition by using an electronic angle meter. A dedicated servo deflection accuracy testing fixture is designed to support the electronic angle meter and is integrated with servo testing software. The servo deflection accuracy testing fixture transfers the test results of the highly integrated servo to the electronic angle meter for direct display. The servo testing software then reads the data from the electronic angle meter, achieving automatic data acquisition and saving for the highly integrated servo deflection accuracy test, and directly printing the test results. This reduces the time required for operators to read data during the high-precision servo deflection accuracy testing process for highly integrated servos.

[0027] This invention addresses the requirements for high precision, high efficiency, and high accuracy in testing the rudder deflection of highly integrated servos. By designing and manufacturing a high-precision rudder deflection accuracy testing device and method for highly integrated servos, the invention reduces the number of operators required for rudder deflection accuracy testing by four, improves the rudder deflection accuracy of highly integrated servos from 0.5° to 0.01°, and directly displays the test results using an electronic angle meter, greatly improving the accuracy of the results and significantly increasing the testing efficiency.

[0028] Block diagram: The high-integration servo high-precision servo deflection accuracy testing device consists of a test computer (with high-integration servo test software), an electronic angle meter, servo deflection accuracy testing fixtures, and a process servo compartment.

[0029] Process servo compartment: The highly integrated servo is installed in the process servo compartment to conduct servo deflection accuracy testing. The process servo compartment provides a reference for the servo deflection accuracy testing. In order to ensure the accuracy and precision of the servo deflection accuracy testing, a parallelism requirement of 0.02 between the two end faces in the process servo compartment is required. At the same time, a perpendicularity requirement of 0.02 between the mounting hole of the highly integrated servo in the process servo compartment and the end face is required.

[0030] Rudder deflection indicator fixture: After assembling the drive shaft (5) and the adapter sleeve (8), assemble the inertia block (7) onto the adapter sleeve (8). Adjust the drive shaft (5), adapter sleeve (8), and inertia block (7) to ensure that the parallelism between the inertia block (7) and the reference surface A on the drive shaft (5) meets the requirements. Drive in the pin (1) and use standard screws (10) to fasten the inertia block (7) and the drive shaft (5) together to ensure that the position of the inertia block (7) and the drive shaft (5) does not shift. Then, drill Φ8 pin holes and make connecting pins (6). After connecting the drive shaft (5) and the adapter sleeve (8) with the connecting pins (6), put the flat washer (12) and spring washer (13) on the connecting pins (6) and tighten them with nuts (11). The tooling is designed with clamps (3) to tighten the electronic angle gauge (4). It is tightened on the inertia block (7) by using standard screws (2). At the same time, a special screw (9) is designed to fasten the rudder deflection indicator tooling to the high-integration servo motor.

[0031] Another embodiment of this specification provides a method for testing the high-precision servo deflection accuracy of a highly integrated servo motor, including:

[0032] 1) Install the highly integrated servo motor in the process servo compartment, tighten it with process screws, and then place it on the servo deflection accuracy test platform;

[0033] 2) Install the electronic angle meter in the clamp (3) on the rudder deflection accuracy test fixture, and tighten the clamp (3) with screws (2);

[0034] 3) Connect the data cable that comes with the electronic angle meter to the computer via the USB interface and secure it firmly;

[0035] 4) Place the rudder deflection accuracy tester with electronic angle gauge on the E1 end face of the process cabin, and zero the electronic angle gauge. At this time, the E1 end face of the process cabin is the reference surface for rudder deflection accuracy test.

[0036] 5) Install the rudder deflection accuracy test fixture with electronic angle meter into the high-integration servo motor, and use special screws (9) to fasten the rudder deflection accuracy test fixture onto the high-integration servo motor.

[0037] 6) Open the high-integration servo test software on your computer and follow the high-integration servo test procedure to start the high-integration servo deflection accuracy test.

[0038] 7) During the test, the highly integrated servo rotates to the corresponding angle according to the test command. The corresponding angle of the reached position is displayed on the electronic angle gauge, which is the servo deflection accuracy test result under that command. The highly integrated servo test software reads the value displayed by the electronic angle gauge at this time and stores the read value in the corresponding servo deflection accuracy test report. After the test is completed, it automatically determines whether the test result is qualified. If it is qualified, the test report is printed directly. If it is unqualified, the parameters are adjusted and the servo deflection accuracy is retested until the test result is qualified, and then the test report is printed. The servo deflection accuracy test of the highly integrated servo is completed.

[0039] The highly integrated servo motor and high-precision servo deflection accuracy testing device designed and manufactured in this invention has the following advantages:

[0040] 1) The number of operators required for testing the rudder deflection accuracy of the highly integrated servo motor has been reduced from 5 to 1, reducing the number of operators by 4 and greatly saving human resources.

[0041] 2) Utilizing equipment eliminates manual labor, improving the efficiency of rudder deviation accuracy testing by more than 50%;

[0042] 3) Significantly improves the accuracy of rudder deflection testing, increasing the accuracy from 0.5° to over 0.01°, an improvement of an order of magnitude, resulting in smaller test result errors and ensuring the accuracy of test results;

[0043] 4) The rudder deflection accuracy test automatically generates and prints test reports, reducing the workload of manual copying and eliminating low-level quality problems caused by copying errors.
