Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) engine technology, and in particular to a UAV engine rotor magnet position correction device. Background Technology
[0002] like Figure 7 As shown, the magnets inside the rotor cavity of the drone engine are held in place by balancing putty, and adjacent magnets are fixed together by magnet fixing plates. Due to variations in the amount and thickness of the balancing putty used when attaching the magnets, some magnets may tilt towards the inner cavity of the drone engine rotor. This magnet misalignment can lead to difficulties in starting the drone engine, unstable operation, and inaccurate control. Utility Model Content
[0003] The purpose of this invention is to provide a drone engine rotor magnet position correction device to prevent the magnet from tilting towards the inner cavity of the drone engine rotor, thereby enabling the drone engine to start quickly.
[0004] The drone engine rotor magnet position correction device provided by this utility model includes a base, on which a mounting plate is mounted via a column. An expansion block adapted to the inner cavity of the drone engine rotor is mounted on the mounting plate. A tension block is located in the middle of the expansion block, and a circular spring is located in the groove of the expansion block. The drone engine rotor is located on the outer periphery of the expansion block. A cylinder is provided on the base. The screw of the cylinder passes through the mounting plate and is connected to the tension block.
[0005] Furthermore, a fixing plate is provided above the groove of the tensioning block, and the fixing plate is located above the circular spring.
[0006] Furthermore, the tensioning block has an inverted frustum structure that is thicker at the top and thinner at the bottom. The upper end of the tensioning block is provided with a fixing platform that matches the center hole of the UAV engine rotor, and the middle of the tensioning block is provided with a nut installation clearance hole. The expansion block has an arc-shaped block structure that is thinner at the top and thicker at the bottom, and the expansion block matches the tensioning block.
[0007] Furthermore, the base has columns at its four corners, and cylinders are installed in the space between the base and the columns.
[0008] Furthermore, the mounting plate is provided with mounting holes around its perimeter, through which the mounting plate is connected to the column.
[0009] The drone engine rotor magnet position correction device provided by this utility model has the following beneficial effects: 1. In this utility model, the rotor of the drone engine is mounted on the expansion block. The screw of the cylinder drives the tension block to move downward. The tension block causes the expansion block to expand in all directions. The expansion block presses against the magnet to correct the position of the magnet.
[0010] 2. This utility model uses a tightening block to compress the magnet, causing the magnet, which was originally tilted towards the inner cavity of the drone engine rotor, to come close to the inner wall of the drone engine rotor, effectively preventing the magnet from tilting towards the inner cavity of the rotor.
[0011] Therefore, this invention avoids the magnet tilting towards the inner cavity of the drone engine rotor, which has the positive effect of enabling the drone engine to start quickly, run smoothly, and be precisely controlled. Attached Figure Description

[0013] like Figure 1-6As shown, the UAV engine rotor magnet position correction device provided by this utility model includes a base 1, a mounting plate 2 is provided on the base 1 via a column 11, an expansion block 3 adapted to the inner cavity of the UAV engine rotor 7 is provided on the mounting plate 2, a tension block 5 is provided in the middle of the expansion block 3, a circular spring 4 is provided in the groove of the expansion block 3, and the UAV engine rotor 7 is provided on the outer periphery of the expansion block 3; a cylinder 6 is provided on the base 1; the screw of the cylinder 6 passes through the mounting plate 2 and is connected to the tension block 5.
[0014] like Figure 1-3 As shown, in use, the magnets inside the rotor cavity of the drone engine are first glued in place with balancing putty, and adjacent magnets are fixed together by magnet fixing plates. Before the balancing putty is completely dry, the drone engine rotor 7 is installed on the tensioning block 3 of the mounting plate 2. At this time, a gap is left between the magnet 72 and the outer periphery of the tensioning block 3. Then, the cylinder 6 is activated, and the screw of the cylinder 6 drives the tensioning block 5 to move downward. Figure 4-6 As shown, the tensioning block 5 causes the expansion block 3 to expand in all directions. The expansion block 3 presses against the magnet 72, causing the magnet 72, which was originally tilted towards the inner cavity of the drone engine rotor 7, to come close to the inner wall of the drone engine rotor 7, thus correcting the position of the magnet 72 and effectively preventing the magnet from tilting towards the inner cavity of the rotor.
[0015] like Figure 2 , 5 As shown, a fixing plate 31 is provided above the groove of the tension block 3, and the fixing plate 31 is located above the circular spring 4. After the position of the magnet 72 is corrected, the circular spring 4 can return the tension block to its original position. The fixing plate 31 can prevent the circular spring 4 from moving out of the groove of the tension block 3.
[0016] like Figure 1-6 As shown, the tensioning block 5 has an inverted frustum structure that is thicker at the top and thinner at the bottom. The upper end of the tensioning block 5 is provided with a fixing platform 51 that matches the center hole 71 of the UAV engine rotor 7. A nut mounting clearance hole 52 is provided in the middle of the tensioning block 5. The expansion block 3 has an arc-shaped block structure that is thinner at the top and thicker at the bottom, and the expansion block 3 matches the tensioning block 5. The UAV engine rotor 7 is mounted on the expansion block 3, with the center hole 71 of the UAV engine rotor 7 mounted on the fixing platform 51. The cylinder 6 is activated, and the screw of the cylinder 6 drives the tensioning block 5 downwards. The tensioning block 5 causes the expansion block 3 to expand outwards, pressing against the magnet 72 to correct the position of the magnet 72.
[0017] like Figure 1 , 4 As shown, four columns 11 are provided at the four corners of the base 1, and cylinders 6 are provided in the space between the base 1 and the columns 11. The columns 11 are used to support the mounting plate 2. The cylinders 6 provide tension to the tensioning block 5, causing the expansion block 3 to expand in all directions and correct the position of the magnet 72.
[0018] like Figure 1-6 As shown, mounting plate 2 has mounting holes 21 around its perimeter, through which it is connected to column 11. Bolts pass through the mounting holes 21 to fix mounting plate 2 to column 11, making installation and disassembly convenient.
[0019] The technical solution of this utility model is not limited to the scope of this utility model. All technical contents not described in detail in this utility model are known technologies.
