[0021] Embodiment, refer to Figures 1-8 A modular unmanned aerial vehicle motor tension test system and device, comprising a bearing platform 1 and a shell 2 arranged on the bearing platform 1, the bearing platform 1 is fixed on the ground through foundation bolts, the shell 2 is installed at the upper end of the bearing platform 1, the inner wall of the shell 2 is provided with symmetrical sliding rails 21, the upper end of the shell 2 is provided with a wire hole 22, the upper end of the shell 2 is provided with a speed regulator 23, and the rear end of the shell 2 is provided with a display screen 3; The inside of the shell 2 is mounted with a tension sensor 4, a motor base 5, a fixing frame 6, a motor 7 and a fixing shaft 8.
[0022] Further, the shell 2 is fixedly connected on the bearing platform 1 by bolts, the side wall of the slide rail 21 is fixedly connected with the inner wall of the shell 2, the two ends of the tension sensor 4 are fixedly connected with a screw rod 41 and a fixing rod 42 respectively, the outer wall of the screw rod 41 is slidingly connected with the inner wall of the shell 2, one end of the screw rod 41 penetrating out of the shell 2 is threadedly connected with a limiting block 24, the side outer wall of the limiting block 24 close to the shell 2 is provided with an antiskid pad, one end of the motor base 5 is fixed with one end of the fixing rod 42 through bolts, the side wall of the motor base 5 is fixedly connected with a sliding block 51 slidingly connected with the slide rail 21, one end of the motor base 5 is fixedly connected with the outer wall of the fixing frame 6 through bolts, one end of the motor 7 is fixedly connected with a mounting frame 71 through bolts, one side of the mounting frame 71 is fixedly connected with a positioning rod 72 corresponding to the fixing shaft 8, and the output end of the motor 7 is mounted with a propeller 73. It should be noted that the bearing platform 1 is built by multiple industrial aluminum profiles, is composed of cross-shaped bases and T-shaped supports, is fixed to a concrete base by means of chemical anchors, can effectively reduce the shaking of the frame caused by resonance when the motor 7 rotates, improves the stability of the device, reduces the measurement error, the aluminum profiles are locked by T-shaped nuts and bolts through corner codes, the shell 2 is placed on the plane at the top of the bearing platform 1 and is also locked by T-shaped nuts and bolts, a galvanized steel plate shielding layer is laid on the inner wall of the shell 2, the part of the mounting frame 71 for connecting the motor 7 is provided with an elongated waist-shaped hole, various sizes of the motor 7 can be connected through bolts, meanwhile, the motor 7 is equipped with different types of propellers 73, the quick replacement of the motor 7 can be realized, and the test efficiency is improved, the front end of the tension sensor 4 is fixed on the inner wall of the motor base 5 through bolts, the tail end screw rod 41 of the sensor penetrates through the shell 2 and is screwed into the limiting block 24 for fixation, the contact surface between the limiting block 24 and the shell cover is provided with an antiskid pad, so as to improve the maximum locking torque of the contact surface and effectively eliminate the rotating torque of the motor 7, the display screen 3 is located at the rear end of the shell 2, the signal wire harness of the tension sensor 4 is led out from the wire hole 22 and connected to the display screen 3, during the test work, the knob of the speed regulator 23 is slowly turned to accurately control the steering and rotating speed of the motor 7, meanwhile, the propeller 73 starts to rotate to convert kinetic energy into aerodynamic thrust, the thrust pushes the motor 7 assembly to slide along the slide rail 21 in the axial direction, the force is transmitted to the tension sensor 4 through the motor base 5, the elastomer of the tension sensor 4 is deformed to generate voltage change, and then the real-time tension value is displayed, so as to complete the test of the tension of the motor 7; One end of the fixed shaft 8 is fixed on the mounting hole of the fixed frame 6 by bolts, which ensures the stability of the overall structure. During the installation of the motor 7, the operator needs to accurately align the connecting position of the end of the fixed shaft 8 with the multiple cylindrical positioning rods 72 uniformly distributed on one side of the mounting frame 71, and then smoothly insert along the axial direction. When the front end of the positioning rod 72 contacts the wedge-shaped positioning block 92 arranged on the inner wall of the limiting groove 81, the end surface of the positioning rod 72 will form close contact with the inclined guide surface of the positioning block 92 designed in advance. At this time, the operator needs to apply appropriate axial thrust to make the side wall of the positioning rod 72 slide along the inclined surface of the positioning block 92. In this process, the positioning block 92 is constrained by the limiting groove 81 and moves towards the inside of the mounting groove 922, while compressing the preloaded spring 93 inside the groove, making it elastically deformed and shrink in the axial direction. When the positioning rod 72 completely passes the blocking position of the positioning block 92, the compressed spring 93 will immediately release the stored elastic potential energy and push the positioning block 92 to quickly rebound to the initial position. At this time, the horizontal positioning surface of the positioning block 92 will tightly fit on the end surface of the positioning rod 72, forming a reliable mechanical limiting, thereby ensuring the accurate positioning of the motor 7 in the axial and circumferential directions, and finally achieving the stable installation of the motor 7. Through the setting of the plug-in fixing assembly, the installation of the motor 7 can be quickly completed, the installation difficulty is reduced, and the speed of testing different types of motors 7 is improved.
[0023] Further, four circumferentially symmetrical limiting grooves 81 are arranged on the inner wall of the fixed shaft 8. A sliding plate 9 is slidably connected to one side of the inner wall of the limiting groove 81. A slide rod 91 is fixedly connected to one side of the sliding plate 9. A positioning block 92 is slidably connected to the outer wall of the slide rod 91. An inclined surface is arranged on one side of the positioning block 92. The inner wall of the fixed shaft 8 and the outer wall of the positioning rod 72 are slidably connected. An installation groove 922 is arranged on one end of the positioning block 92 close to the sliding plate 9. A spring 93 is fixedly connected between the installation groove 922 and the sliding plate 9, and the spring 93 is sleeved on the outer wall of the slide rod 91. An annular groove 82 is arranged on the side wall of the fixed shaft 8 at the upper end of the positioning block 92. An adjusting frame 10 is installed between the fixed frame 6 and the motor 7. An adjusting rod 101 is fixedly connected to the outer wall of one side of the adjusting frame 10. The outer wall of the adjusting rod 101 is slidably connected to the outer wall of the shell 2. An annular sleeve 102 is fixedly connected to one end of the adjusting frame 10 and slidably connected to the outer wall of the annular groove 82. A plurality of plug rods 103 are fixedly connected to the inner wall of one side of the annular sleeve 102 and slidably connected to the inner wall of the fixed shaft 8. A plurality of rolling balls 104 are rollingly connected to the inner wall of one end of the plug rod 103. The outer wall of the rolling ball 104 is rollingly connected to the inner wall of the rolling groove 921.
[0024] It should be noted that: in order to facilitate the quick disassembly of the motor 7 during equipment maintenance or model replacement, the adjusting rod 101 located on the side of the equipment needs to be pushed during the disassembly operation, and the movement of the adjusting rod 101 will drive the entire lower end adjusting frame 10 connected thereto to move, and during the movement of the adjusting frame 10, the multiple loop sleeves 102 evenly distributed on the side wall thereof will smoothly slide along the loop grooves 82 pre-processed on the outer side of the different fixed shafts 8, and at the same time during the sliding process, the multiple insertion rods 103 arranged on one side of the adjusting frame 10 will smoothly slide in the inner wall groove of the fixed shaft 8, and the ball 104 installed at the end of each insertion rod 103 will be tightly abutted on the inner side wall surface of the loop groove 82, and the force generated by this contact mode will force the positioning block 92 to move downward along the vertical direction.
[0025] During the movement of the positioning block 92, due to the structure limitation of the limiting groove 81 precisely processed on the fixed shaft 8, the inclined surface designed at the lower end of the positioning block 92 will smoothly slide along the corresponding guide inclined surface in the limiting groove 81, and the horizontal position of the positioning block 92 can be automatically adjusted by its sliding on the sliding rod 91, and the vertical position thereof is precisely controlled by the synchronous linkage movement of the sliding plate 9 connected at one end of the sliding rod 91, and this double adjustment mechanism ensures that the positioning block 92 can be accurately shrunk into the internal space of the limiting groove 81, so as to completely release the structural limitation of the positioning rod 72 on the motor 7, at this time, the worker only needs to apply a moderate axial force to the motor 7 outward, so as to easily slide it out along the guide rail, and through the structure of the carefully designed disassembly assembly, not only the quick disassembly of the motor 7 can be realized, and the equipment maintenance time is greatly shortened, but also the operation is simple and reliable without using additional tools during the disassembly process, so as to significantly improve the work efficiency of testing and replacing different models of the motor 7.
[0026] It should be noted that the specific model specification of the motor needs to be selected and determined according to the actual specification of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.
[0027] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
