[0034] Specifically, in order to solve the problems of large positioning accuracy deviation and inconvenient adjustment after multiple uses of the interface positioning tooling in the prior art; the interface positioning device for UAV assembly provided by the present invention can connect the structural interface of the UAV by measuring the first surface of the connecting piece 1, and install an angle measuring component on the second surface parallel to the first surface, and use the angle measuring component to measure the inclination angle of the second surface, and use this as the angle measurement result of the structural interface of the UAV, so as to realize real-time measurement of the structural interface of the UAV, and can compare it with the set angle, so as to adjust the angle of the structural interface of the UAV by adjusting the components of the UAV where the structural interface of the UAV is located. During the adjustment process, the adapter 3, the horizontal displacement platform 4 and the height displacement platform 5 follow up until the adjustment is completed. After completion, the horizontal displacement stage 4 and the height displacement stage 5 can be locked by the locking structure, and at the same time, the real-time measurement of the angle measuring component can be cooperated to realize the positioning of the structural interface of the UAV, and then the precise positioning and assembly of the components of the UAV where the structural interface of the UAV is located can be realized, which not only can realize the positioning adjustment of the structural interface of the UAV, but also the real-time measurement of the adjustment accuracy can ensure the accuracy of the adjustment; in addition, the locking structure of the horizontal displacement stage 4 and the height displacement stage 5, in conjunction with the angle measuring component on the measuring connector 1, can conveniently determine the position of the structural interface of the UAV, which is convenient for the subsequent installation of devices or parts. By recording the data of the angle measuring component, the operator can be more convenient and accurate in the next assembly and adjustment of the structural interface of the UAV.

[0035] In this embodiment, the horizontal displacement platform is a heading displacement platform; the horizontal displacement platform and the height displacement platform are both follow-up displacement platforms, which are shelf commodities.

[0036] Optionally, a first rotating connection ear is provided at the lower end of the measuring connecting piece 1, a second rotating connection ear is provided on the top surface of the adapter seat 3, and the first rotating connection ear is rotatably connected to the second rotating connection ear through a horizontally arranged rotating shaft 2.

[0037] Specifically, the rotational connection between the first rotational connection ear and the second rotational connection ear can be realized by passing the rotation shaft 2 through the first rotational connection ear, so that the pitch angle of the measuring connection member 1 can be conveniently adjusted.

[0038] In this embodiment, two second rotating connecting ears are provided, and the first rotating connecting ear is provided between the two second rotating connecting ears.

[0039] Furthermore, in order to achieve the positioning of the measuring connection member 1, a locking component can also be set on the first rotating connection ear or the second rotating connection ear or the rotating shaft 2 to lock the measuring connection component so that its relative position with the adapter 3 is fixed.

The four points are fitted into an interface plane through the laser tracker, and the interface plane angle is calculated to achieve measurement of the second surface and the structural interface angle. The position of the positioning hole of the square plate on the measuring connector 1 is measured by the angle measuring component, so the inclination angle state of the structural interface can be grasped in real time, which is more convenient than traditional measurement and calculation. The angle measurement component is measured by a laser tracker, which has higher accuracy than traditional measurement methods.

[0046] Optionally, the connection plate is provided with a plurality of connection holes arranged circumferentially, and the connection holes are used for connecting the structural interfaces.

[0047] Specifically, a connecting plate with a plurality of connecting holes forms a flange structure, and the flange can be used to connect to the structural interface of the UAV. Of course, a clamp can also be used to achieve a fastened connection between the structural interface and the connecting plate according to the structure of the structural interface.

[0048] Furthermore, the measuring connector 1 can be adapted to different structural interfaces by changing the structure of the connecting plate of the structural interface with the drone, thereby increasing versatility.

[0049] Optionally, the measuring plate is rotatably connected to the adapter seat 3 via the rotating shaft 2 .

[0050] Specifically, the first rotating connecting ear is arranged on the lower side of the square plate, and is rotatably connected to the second rotating connecting ear connected to the upper side of the rotating seat through the rotating shaft 2.

[0051] Optionally, the bottom plate of the height displacement platform 5 is provided with fixing holes, and the fixing holes are used to fix the interface positioning device used for assembling the drone.

[0052] Specifically, the bottom plate of the height displacement platform 5 can be fixed to the tooling platform or supporting profile on the ground or the UAV through the fixing holes, so as to fix the relative position of the fixed end of the height displacement platform 5 and the UAV.

[0053] like Figure 2 As shown, the present invention also provides an interface positioning method for unmanned aerial vehicle assembly, using the above-mentioned interface positioning device for unmanned aerial vehicle assembly, the method comprises:

[0058] The horizontal displacement stage 4 and the height displacement stage 5 are locked to fix the position of the measuring connection member 1 .

[0059] Optionally, the structural interface of the drone is arranged on a component of the drone that rotates around a set axis.

[0060] Specifically, the interface positioning method for UAV assembly is used to position the structural interface on the component of the UAV that rotates around a set axis, and then conveniently adjust and control the assembly accuracy of the component that rotates around the set axis by positioning the structural interface.

[0061] In summary, when the interface positioning method for assembling a drone is used, the above-mentioned interface positioning device for assembling a drone is used to position the structural interface on a component of a drone that rotates around a set axis. First, the above-mentioned interface positioning device for assembling a drone is fixed to the ground or a tooling platform on the drone through the fixing holes on the bottom plate of the height displacement table 5, so that the relative position of the fixed end of the height displacement table 5 and the drone is fixed; then, the first surface of the measuring connector 1 is connected to the structural interface of the drone through the follow-up horizontal displacement table 4 and the height displacement table 5 and the rotation connection between the measuring connector 1 and the adapter 3. Before that, It is necessary to ensure that the components rotating around the set axis at the structural interface have been pre-assembled so that they can only rotate around the set axis; then use the laser tracker software to calculate the inclination angle of the measured plane, that is, the second surface. Since the first surface is parallel to the second surface, the measured inclination angle is the real-time structural interface angle; then, according to the comparison result of the inclination angle and the set angle, the measuring connector 1 and the components rotating around the set axis are fine-tuned, and finally the structural interface angle that meets the accuracy requirements and the precise assembly position of the components rotating around the set axis are obtained; finally, the height displacement stage 5 and the horizontal displacement stage 4 are locked by the locking structure, and the interface positioning adjustment of the UAV assembly is completed.

[0062] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.
