Technical Field

[0001] The present application relates to the technical field of steering gear testing, and in particular to a multi-unit quick-disassembly and assembly positioning device for steering gear testing. Background Art

[0002] As the actuator of the control system, the servo is mostly used in the flight attitude control systems of UAVs, aircrafts, missiles, etc. Its mechanical parts are mostly composed of motors, couplings, reducers, and control surface loads. In recent years, as the application field of servos has developed towards miniaturization, lightness, low cost, high precision, and high response, the performance requirements for servos have also gradually increased.

[0003] In order to verify the stability and performance compliance rate of the servo during operation, it is necessary to conduct an operation test on the servo. Currently, there is no special positioning device for servo testing, and simple tests are performed directly on a flat surface such as a table; or the special test device has too many integrated functions and a complex structure, resulting in a cumbersome installation process and low test efficiency, making it impossible to conduct large-scale tests on servos. Summary of the invention

The servos can be directly inserted into the positioning grooves, and a plurality of servos can be fixed at the same time for testing. The servos are easy to install and disassemble, and the testing efficiency is high.

[0007] In some embodiments, the support and limit assembly includes a support platform and a limit block, the top of the support platform is provided with a contoured surface matching the contour of the bottom surface of the reducer housing of the servo, the contoured surface abuts the bottom surface of the reducer housing of the servo, and the top surface of the limit block abuts the reducer end cover of the servo; the bottom surface of the reducer housing is supported by the contoured surface of the support platform, thereby improving the stability of the servo installation; the end cover of the reducer is abutted by the top surface of the limit block, thereby avoiding the servo from tilting toward the end cover due to the excessively high center of gravity, thereby further improving the stability of the servo fixation.

[0008] In some embodiments, a groove is provided at the bottom of the end surface of the end cover, the top surface of the groove abuts against the top surface of the limit block, and the outer side surface of the groove abuts against the inner side surface of the limit block; a side of the reducer housing close to the end cover is provided with a boss extending outward, and a side of the boss facing away from the end cover abuts against the inner side surface of the support platform; by the inner side surface of the limit block abutting against the outer side surface of the groove, and by the side surface of the boss abutting against the inner side surface of the support platform, the front and rear directions of the servo can be limited, thereby preventing the servo from being displaced during the test, and further improving the stability of the servo test.

[0009] In some embodiments, a buffer pad is provided on the side wall of the positioning groove.

During the specific implementation process, the profiling surface 8 can be adjusted according to the different shapes of the servo 4, and is used to support the reducer of the servo 4 to keep the servo 4 in a vertical posture for easy testing.

[0030] Please continue reading Figures 1 to 4 In some embodiments, a groove 10 is provided at the bottom of the end surface of the end cover 9 (the groove 10 is the original structure on the end cover 9, which is convenient for drilling holes to install screws, and the purpose of providing the groove 10 is to reduce the depth of the drilling hole), the top surface of the groove 10 abuts against the top surface of the limit block 6, and the outer side surface of the groove 10 abuts against the inner side surface of the limit block 6; a boss 11 extending outward is provided on the side of the reducer housing close to the end cover 9 (the boss 11 is the original structure of the reducer housing 7), and a side of the boss 11 facing away from the end cover 9 abuts against the inner side surface of the support platform 5; by the inner side surface of the limit block 6 abutting against the outer side surface of the groove 10, and by the side surface of the boss 11 abutting against the inner side surface of the support platform 5, the front and rear directions of the servo 4 can be limited, the servo 4 can be prevented from being displaced during the test, and the stability of the servo 4 test is further improved.

[0031] Please continue reading Figure 1 In some embodiments, a buffer pad 12 is provided on the side wall of the positioning groove 3.

[0032] In a specific embodiment, the buffer pad 12 can be a rubber pad or other flexible materials, and can be bonded to the inner wall of the positioning groove 3 by using adhesive.

[0033] Please continue reading Figure 1In some embodiments, a chamfered structure 13 is provided at the intersection of the side wall of the positioning groove 3 and the top surface of the base 2, the purpose of which is to facilitate the servo 4 to quickly snap into the positioning groove 3, thereby improving the installation efficiency of the servo 4; it can also prevent the servo 4 from colliding with the top opening of the positioning groove 3 when being snapped in.

[0034] In some embodiments, the bottom plate 1, the base 2 and the support and limiting assembly are an integrally formed structure and can be directly formed by a customized mold, so that the structure is more solid.

[0035] The quick installation and removal process of the positioning device of this embodiment is as follows:

[0036] During quick installation, the motor 14 of the steering gear 4 is held, and the reducer of the steering gear 4 is facing downward, so that the side wall of the steering gear 4 is guided by the open chamfered structure 13 of the positioning groove 3 and flexibly cooperates with the buffer pad 12 of the inner wall of the positioning groove 3, so as to complete the displacement constraint of the steering gear 4 in the left and right directions, and make the bottom of the reducer housing 7 roughly aligned with the contoured surface 8 of the support platform 5, and the steering gear 4 slides down smoothly along the buffer pad 12 under the action of its own gravity until the bottom surface of the reducer housing 7 fits with the contoured surface 8 to form a small gap fit; then, by adjusting the front and rear position of the steering gear 4, the top surface of the limit block 6 is abutted against the top surface of the groove 10, the inner side surface of the limit block 6 is abutted against the outer side surface of the groove 10, and the inner side surface of the support platform 5 is abutted against the side surface of the boss 11, so as to complete the displacement constraint of the steering gear 4 in the front and rear directions, thereby completing the rapid positioning of the steering gear 4, and the steering gear 4 can be directly tested later.

[0037] During quick disassembly, the motor 14 of the servo 4 can be directly held and the servo 4 can be taken out upwards. When taking it out, it is only necessary to overcome the gravity of the servo 4 and the friction between the servo 4 and the buffer pad 12 without any other resistance.
