Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV motor disassembly device. Background Technology

[0002] When a drone's motor needs repair or replacement, it must be disassembled. Typically, the motor is placed on a support, and then the motor shaft is struck with a hammer and iron bar to detach the rotor from the stator for maintenance or replacement. However, this method requires two people: one to assist and the other to strike. This can easily damage the motor's structural components, and serious operational errors can even cause injury. This disassembly method is time-consuming and labor-intensive. Alternatively, there is a simple disassembly tooling, but one tooling set can only be used for one drone model, resulting in limited compatibility. Utility Model Content

[0020] Please combine Figure 1 and Figure 2 This utility model provides a drone motor disassembly device 100 (hereinafter referred to as the disassembly device) for disassembling the shaft 210 of a drone motor 200. The disassembly device includes a support frame 10, a worktable 20 disposed on the support frame 10, and a top shaft assembly 30 disposed above the worktable 20.

[0021] The workbench 20 has a top shaft hole 21 and a plurality of mounting holes 22 arranged around the top shaft hole 21. The mounting holes 22 are used to pass screws through and fix them to the fixing structure 220 on the motor, so that the motor of the UAV is installed on the bottom surface of the workbench 20 and the rotating shaft of the motor is aligned with the top shaft hole 21.

[0022] The top shaft assembly 30 includes a top shaft member 31 and an adapter member 32. The adapter member 32 is stepped and includes a plug portion 321, a limiting boss 322, and an inner hole 320 passing through the plug portion 321 and the limiting boss 322.

The adapter member 32 can be interchangeably installed on the worktable 20 to adapt the top shaft member 31 to the shafts of different motors.

[0023] The UAV disassembly device of this utility model fixes the motor on the workbench 20, and sets the top shaft assembly 30 on the workbench 20 to act on the motor shaft, which can push the motor shaft out. The top shaft assembly 30 is equipped with a replaceable adapter 32 to adapt to the motors of different models, which improves the adaptability of the disassembly device. Different models of motors can be disassembled by one disassembly device, reducing the cost of motor disassembly.

[0024] In one embodiment, the top shaft hole 21 is a threaded hole, and the outer circumference of the insertion part 321 is provided with an external thread adapted to the threaded hole. The adapter 32 is threadedly connected to the worktable 20. Therefore, different adapters 32 and different top shaft parts 31 can be used for different motor models. The adapter 32 and the top shaft part 31 are fitted together with a clearance fit to limit the movement of the top shaft part 31, preventing uneven force distribution and deformation of the parts during hammering.

[0025] In one embodiment, the bottom surface of the limiting boss 322 abuts against the worktable 20 to limit the installation position of the adapter 32, the top surface of the limiting boss 322 abuts against the preset limiting structure 312 on the top shaft 31 to limit the downward stroke of the top shaft 31, and the circumferential sidewall of the limiting boss 322 is set as a polygonal structure adapted to the drive wrench to facilitate the disassembly of the adapter 32.

[0026] In one embodiment, the mounting hole 22 is configured as an oblong hole extending radially along the top shaft hole 21.

[0027] In one embodiment, the workbench 20 is provided with a plurality of hole groups, each hole group including a plurality of mounting holes 22 arranged around the top shaft hole 21. The mounting holes 22 of the plurality of hole groups are alternately arranged along the circumference of the top shaft hole 21. The width of the mounting holes 22 in different hole groups is different and / or the spacing relative to the top shaft hole 21 is different, so as to accommodate the installation of motors of different models.

[0028] Preferably, there are two hole groups, each with four mounting holes 22, and the mounting holes 22 of the two hole groups are arranged alternately.

[0029] The mounting holes 22 in each hole group have the same width and length, and the included angle between two adjacent mounting holes 22 is a right angle.

[0030] Preferably, the mounting hole 22 of one hole group is located on the angle bisector of the adjacent mounting hole 22 of another hole group.

[0031] In one embodiment, the support frame 10 includes a base plate 12 disposed below the workbench 20, and multiple support columns 11 disposed between the workbench 20 and the base plate, connecting the workbench 20 and the base plate into a whole. The support columns are connected to the workbench 20, and the base plate is used to receive the rotating shaft that is pushed out and falls by the top shaft member 31.

[0032] In one embodiment, a support plate 111 is provided at the top of the support column 11, and both the workbench 20 and the support plate 111 are provided with connecting holes (see...). Figure 2 The workbench has a connection hole of 23, and the support plate has a connection hole of 1111. The disassembly device also includes connecting bolts 40 that pass sequentially through the connection holes on the workbench 20 and the support plate. The support plate allows the support column 11 to be connected to the workbench 20, and the connection is made via the connecting bolts, enabling a detachable connection between the support plate and the workbench 20. This facilitates the replacement of support columns of different lengths to accommodate the disassembly of motors of different heights. The support plate can be welded to the top of the support column.

[0033] In another embodiment, the support column 11 is welded to the worktable 20.

[0034] In one embodiment, the support column 11 is designed to be telescopic, thereby adjusting the distance between the base plate of the support frame 10 and the workbench 20 to accommodate the disassembly of motors of different heights.

[0035] In addition, the support frame 10 also includes a support plate (not shown in the figure, the same below) rotatably sleeved on the support column 11. The support plate is used to rotate to the bottom of the motor and support the motor. The support plate has a clearance hole corresponding to the top shaft hole 21 for the motor shaft to pass through.

[0036] In one embodiment, the support frame 10 further includes a flexible foot pad 13 disposed below the base plate 12. The flexible foot pad is provided with a threaded post, and the bottom of the support post is provided with a threaded hole. The threaded post passes through a pre-set through hole in the base plate and is threadedly connected to the threaded hole. By providing a flexible foot pad, a certain height distance can be maintained between the support frame 10 and the ground, and the impact on the ground during disassembly can also be reduced.

[0037] Please combine Figure 3 In another embodiment, the disassembly device further includes a servo press 50, which is used to apply pressure to the top shaft 31. Using a servo press for press-fitting and disassembly, through the coordinated control of the servo press and PLC, allows for precise control of the position and pressure during the disassembly process, effectively avoiding overpressure or underpressure. For material tolerances or mold wear, the system can automatically adjust the press-fitting parameters based on real-time monitoring data to achieve dynamic compensation. Using a servo press to apply pressure can improve disassembly efficiency and reduce the damage rate of parts.
