Description

Technical Field

[0001] The utility model belongs to the technical field of drilling processing devices, and in particular relates to a drilling device for a support member of an unmanned aerial vehicle. Background Art

[0002] In order to ensure the streamlined exterior and internal space of large unmanned aerial vehicles, many arc-shaped support members are usually provided. The support members are generally arc-shaped in structure, and connecting plates are provided at both ends. The connecting plates are usually arranged toward the inner arc surface of the support members to ensure the integrity of the outer arc surface structure of the support members. To facilitate installation and fixation, the connecting plates at both ends of the support members are usually processed with a number of connecting holes, which are mainly through holes or threaded holes. To ensure the positional accuracy of the parts assembly and to make the two ends of the support members interchangeable, the connecting holes on the connecting plates at both ends of the support members are arranged in a symmetrical structure, that is, the corresponding connecting holes on the connecting plates at both ends need to be coaxial. If the existing radial drilling machines or horizontal drilling machines need to meet the above-mentioned processing requirements, they can only mark first and then drill holes. In addition, when drilling holes, the positions of the two ends of the support members need to be reversed and adjusted to complete the processing of the connecting holes on the connecting plates at both ends. The whole process is relatively cumbersome, which also leads to low drilling efficiency. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, the utility model provides a drilling device for a UAV support member, which can effectively ensure the symmetry of the connection holes processed at both ends of the support member and has higher processing efficiency.

[0005] A drilling device for a support member of an unmanned aerial vehicle, comprising:

[0006] A horizontally arranged workbench has two mutually parallel support plates vertically arranged on its top. The two support plates are arranged to move along the connecting line direction. Positioning steps are provided on the tops of the opposite sides of the support plates for connecting the ends of the support members. The extending direction of the positioning steps is parallel to the top surface of the workbench and perpendicular to the moving direction of the support plates.

[0007] The cantilever bracket is arranged on one side above the workbench, and a drill is rotatably provided at the front end of the cantilever bracket, the rotation axis is perpendicular to the top surface of the workbench, and the rotation angle is 0° to 180°, the drill bit of the drill is parallel to the top surface of the workbench, and when the drill is rotated to 0° or 180°, the drill bit is perpendicular to the support plates on both sides respectively, and the positions of the drill bits are coaxial; the cantilever bracket is movably arranged along the moving direction of the support plate, and the cantilever bracket is movably arranged along the direction perpendicular to the top surface of the workbench.

[0008] The beneficial effects of the utility model are that: this scheme can effectively ensure the coaxial accuracy of the corresponding connecting holes on the connecting plates at both ends of the support member, so that the connecting holes at both ends of the support member are symmetrical with each other, so as to make the support members interchangeable; and during the drilling process, there is no need to mark and reverse the positions of the two ends of the support member, which can effectively shorten the drilling time and improve the drilling efficiency.

After the hole processing is completed, the drill 4 is rotated to the 180° position to make the drill bit point to the connecting plate at the other end of the support member, and the cantilever bracket 3 is moved to move the drill 4 toward the connecting plate to be drilled, and the connecting plate is drilled with the drill bit.

By rotating the adjusting screw 17, the transverse guide rail 16 can be driven to move on the longitudinal guide rail 15, and the self-locking function of the thread can be used to prevent the transverse guide rail 16 from sliding off.
