Description

Technical Field

[0001] The utility model belongs to the field of servo controllers, and in particular relates to a device for testing a lower rotor servo valve actuator. Background Art

[0002] A servo drive, also known as a "servo controller," is a controller used to control a servo motor. Its function is similar to that of a frequency converter on an ordinary AC motor. It is part of a servo system and is primarily used in high-precision positioning systems. Current servo controllers use computer control to implement servo control and testing of actuators, using signal generators to simulate onboard control commands. The servo control portion of the equipment drives the main control surface actuator, achieving the same control accuracy as onboard control. It automatically collects various actuator data and can measure zero bias, internal leakage, and position accuracy.

[0003] Current servo controllers can stably detect actuator data when in use. However, in actual use, workers are required to manually install the actuator inside the servo controller, and subsequently attach the detection element to the end of the actuator. This method wastes a certain amount of working time and affects overall work efficiency. Utility Model Content

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0025] Depend on Figure 1 As shown, it is a structural diagram of the lower rotor servo valve actuator test equipment in this embodiment, and the test equipment includes a shell 1, a control box 2 and a detection chamber 3. The control box 2 for testing the operating data of the actuator is installed in the shell 1, and the detection chamber 3 is installed at the bottom end of the shell 1. The detection chamber 3 is installed with a clamping mechanism 4 for quick installation of the actuator.

[0026] During use, the actuator to be tested is placed inside the testing chamber 3, and the two ends of the actuator are clamped and fixed by the operation of the clamping mechanism 4. Then, under the operation of the control box 2, the actuator is stably tested, which simplifies the installation steps of the actuator and ensures the working quality of the equipment itself.

[0027] By the attached Figure 2 As shown, it is a structural diagram of the clamping mechanism 4 in this embodiment, the driving component 41 is installed on the side of the detection chamber 3, the connecting plate 42 is slidably installed inside the detection chamber 3, and there are two groups of connecting plates 42. The connecting plates 42 pass through the side walls of the detection chamber 3 and are connected to the driving component 41, and the clamping member 43 is installed at the end of the connecting plate 42.

[0028] During use, the actuator is placed between the two sets of clamps 43. Then, under the operation of the drive assembly 41, the two sets of clamps 43 move toward the middle end at the same time to squeeze and clamp the actuator in the middle end, so that the components in the clamps 43 can fit stably with the actuator, which is convenient for subsequent control box 2 to test the actuator.

[0029] By the attached Figure 3 As shown, it is a structural schematic diagram of the drive component 41 in this embodiment, which includes a side shell 411, a bidirectional screw rod 412, a movable end 413, a drive motor 414 and a guide rod 415. The side shell 411 is fixedly installed on the side of the detection chamber 3, the bidirectional screw rod 412 is rotatably installed inside the side shell 411, and the movable end 413 is symmetrically threadedly installed on the outside of the bidirectional screw rod 412. The movable end 413 is fixedly connected to the connecting plate 42, the drive motor 414 is installed at the top of the side shell 411, and the output end of the drive motor 414 is connected to the bidirectional screw rod 412. The guide rod 415 is fixedly installed inside the side shell 411, and the guide rod 415 is parallel to the bidirectional screw rod 412. The guide rod 415 is slidingly connected to the movable end 413.

[0030] During use, the bidirectional screw rod 412 rotates inside the side shell 411 by starting the drive motor 414. At this time, the movable end 413 moves along the external thread of the bidirectional screw rod 412, driving the two sets of connecting plates 42 to drive the side clamping parts 43 to move closer to the middle end, clamping and positioning the actuator at the middle end, and assisting subsequent equipment in the stability detection of the actuator.

[0031] By the attached Figure 4 As shown, it is a structural schematic diagram of the clamping member 43 in this embodiment. The clamping member 43 includes a clamping plate 431, a detection element 432 and a connecting wire 433. The clamping plate 431 is installed at the end of the connecting plate 42, the detection element 432 is installed on the surface of the clamping plate 431, and the connecting wire 433 passes through the clamping plate 431 and is electrically connected to the detection element 432.

[0032] During use, the clamping plate 431 is fitted against the bottom end of the actuator to assist in positioning the actuator, and the detection element 432 is stably in contact with the bottom surface of the actuator. As the connecting plate 42 squeezes itself, the squeezing force of the clamping plate 431 and the actuator realizes load changes. The detection element 432 detects and transmits data, which facilitates the control box 2 to stably detect and test the actuator.

[0033] By the attached Figure 5 As shown, it is a structural diagram of the positioning mechanism 5 in this embodiment. The test equipment also includes a positioning mechanism 5, and the positioning mechanism 5 includes a rotating frame 51 and a limit frame 52. The rotating frame 51 is symmetrically installed on the inner wall of the detection chamber 3, and the limit frame 52 is rotatably installed on the side of the rotating frame 51. During use, the limit frame 52 rotates stably in the rotating frame 51. By utilizing the operation and angle changes of the two groups of limit frames 52, the limit frame 52 fits against the side wall of the actuator to perform preliminary positioning on the actuator at the middle end.

[0034] The positioning mechanism 5 also includes an inclined plate 53 and a torsion spring 54. The inclined plate 53 is installed at the end of the limit frame 52, and the torsion spring 54 is symmetrically arranged in the rotating frame 51. During use, the torsion spring 54 will release its own elastic force, driving the two groups of limit frames 52 to deflect toward the middle end at the same time, squeezing the side wall of the actuator, and a blocking rod is installed inside the rotating frame 51 to limit the rotation angle of the limit frame 52. In conjunction with the inclined plate 53, it can prevent the two groups of limit frames 52 from being completely closed. In conjunction with the inclined plate 53, the actuator can be quickly installed in the limit frame 52.

[0035] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
