Description

Technical Field

[0001] This utility model relates to the technical field of blade oscillation detection devices, specifically a detection device for blade oscillation. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices. The term "UAV" is actually a general term for unmanned aerial vehicles, which can be technically categorized as: unmanned fixed-wing aircraft, unmanned vertical takeoff and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, and unmanned paragliders. Compared to manned aircraft, they have advantages such as smaller size, lower cost, ease of use, lower requirements for the combat environment, and stronger battlefield survivability. The two blades of a UAV's rotor blades have different swing torques; excessive torque can prevent the blades from opening during startup, necessitating the measurement of the torque between the two blades.

[0003] When using the existing testing fixture, the positions of the thrust gauge and the stop bar need to be switched manually when testing the forward and reverse blades. Each blade clamp needs to be measured twice, which is inefficient. Relying on manual labor can easily lead to missed measurements and the quality cannot be guaranteed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a detection device for blade oscillation. Through the setting of a base, two digital thrusters, a stop bar, a fixed mold, a rotating shaft and a servo motor, the servo motor is made to first reverse 90 degrees for testing, and then rotate forward 180 degrees for testing. The motor rotation replaces manual rotation, the measurement speed and angle are stable, and the missed detection is eliminated, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detection device for blade oscillation, comprising a base, two digital thrusters arranged symmetrically on the upper side of the base, a fixed mold at the symmetrical point of the two digital thrusters, a rotating shaft connected to the lower side of the fixed mold, a servo motor connected to the lower side of the rotating shaft, a blade connected to the upper side of the fixed mold, a stop bar on the side of the blade away from the digital thrusters, a fixing bar connected to the lower end of the stop bar, a forward / reverse switching button on one side of the base, the digital thrusters can be arranged on both sides of the blade, when the blade rotates, the blade can push the digital thrusters, so that the digital thrusters can measure the torque of the blade, the servo motor provides power for the rotation of the rotating shaft, and at the same time can precisely control the rotation angle of the rotating shaft, thereby precisely controlling the rotation angle of the blade.

[0006] Furthermore, a touch screen is provided on one side of the forward / reverse switching knob, and a start button is provided on the side of the touch screen away from the forward / reverse switching knob. The touch screen facilitates the testing personnel to set testing data, and the start button can start the testing device and power on the servo motor.

[0007] Furthermore, a stop button is provided below the start button, and handles are installed on both outer sides of the base. The handles make it convenient for testing personnel to carry the base, thus facilitating its transport and use.

[0008] Furthermore, the handle is connected to the base housing by bolts, the touch screen is connected to the base by screws, and the digital thruster is fixedly connected to the upper side of the base.

[0009] Furthermore, the digital thruster has a thrust disk facing the blade, and a rubber sleeve is fitted on the baffle. The baffle can block the rotating blade, and the flexible structure can block and protect the blade to avoid damage.

[0010] Furthermore, the touch screen has a built-in PLC controller programming module. The fixed module is fixedly connected to the rotating shaft. The built-in PLC controller module of the touch screen allows the testing personnel to program the rotation angle and rotation speed of the servo motor, ensuring that the rotation speed of the servo motor driving the rotating shaft and blades meets the requirements.

[0016] like Figure 1-4 As shown, during testing, the blade 9 is installed on the fixed mold 10, the start button 5 is pressed, and the servo motor 12 is adjusted through the touch screen 3, so that the servo motor 12 drives the rotating shaft 11 to rotate, which in turn causes the fixed mold 10 to drive the blade 9 to rotate counterclockwise by 90 degrees, and then clockwise by 180 degrees. The digital thrust machine 7 can be pushed by the blade 9, thereby measuring the torque of the blade. The rotation of the servo motor 12 replaces manual rotation, ensuring stable measurement speed and angle, and eliminating missed defects.

[0017] A touch screen 3 is located on one side of the forward / reverse switch 4, and a start button 5 is located on the side of the touch screen 3 away from the forward / reverse switch 4. The touch screen 3 allows the testing personnel to easily set the rotation angle of the servo motor and adjust the speed of the servo motor 12. The start button 5 allows the operator to easily start the testing equipment.

[0018] A stop button 6 is located below the start button 5. The stop button 6 can be used when a fault occurs or when it is necessary to stop the detection, so that the servo motor 12 stops rotating and the blade can be removed to avoid a larger fault. Handles 2 are installed on both sides of the outer surface of the base 1. The handles 2 are designed to facilitate the carrying and use of the base 1.

[0019] The handle 2 is connected to the outer shell of the base 1 by bolts, the touch screen 3 is connected to the base 1 by screws, the digital thruster 7 is fixedly connected to the upper side of the base 1, and the touch screen 3 facilitates the operator to operate the touch screen and adjust the detection device.

[0021] The touch screen 3 has a built-in PLC controller programming module. The fixed mold 10 is fixedly connected to the rotating shaft 11. The fixed mold 10 can fix the blade 9, and the rotating shaft 11 can drive the fixed mold 10 and the blade 9 to rotate, thereby enabling the blade to perform forward and reverse rotation tests.

[0022] The working principle of the detection device for blade oscillation provided by this utility model is as follows: Figures 1-4 As shown, during testing, the blade 9 is installed on the fixed mold 10, the start button 5 is pressed, and the servo motor 12 is adjusted through the touch screen 3, so that the servo motor 12 drives the rotating shaft 11 to rotate, which in turn causes the fixed mold 10 to drive the blade 9 to rotate counterclockwise by 90 degrees, and then clockwise by 180 degrees. The digital thrust machine 7 can be pushed by the blade 9, thereby measuring the torque of the blade. The rotation of the servo motor 12 replaces manual rotation, ensuring stable measurement speed and angle, and eliminating missed defects.
