[0002] Unmanned aerial vehicles, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by on-board computers. In the production and manufacturing process of drones, after the processing and cutting of the various parts of the drone, their surfaces need to be polished to increase the smoothness of the surface of the parts. In factories with a low degree of mechanization, the polishing operation is usually carried out by grinding and polishing the parts on the operating table with a polishing disc on the polishing machine. When polishing the drone tripod, since most drone tripods have non-planar surfaces such as corners and connecting corners, the polishing operator usually holds the drone tripod close to the polishing wheel for polishing.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1 - Figure 4 A polishing device for the production of unmanned aerial vehicle tripods includes an operating table 1, the upper surface of the operating table 1 is connected to a power bracket 2 and a clamping bracket 3, the power bracket 2 is rotatably connected to a mounting rod 4 on one side close to the clamping bracket 3, the end of the mounting rod 4 away from the clamping bracket 3 penetrates the power bracket 2 and is connected to a power assembly, the end of the mounting rod 4 close to the clamping bracket 3 is connected to a polishing grinding wheel 5, the other side of the polishing grinding wheel 5 is connected to a clamping rod 6, the other end of the clamping rod 6 penetrates the clamping bracket 3 and is connected to a clamping assembly, the end of the clamping rod 6 close to the polishing grinding wheel 5 is rotatably connected to a clamping block 7 through a bearing, and the side of the clamping block 7 away from the clamping rod 6 is against the polishing grinding wheel 5.

[0023] like Figure 1 - Figure 4 As shown, the polishing device for the production of drone tripods in the utility model is similar in structure to the existing polishing device for the production of drone tripods, such as a surface polishing device based on drones disclosed in the patent with publication number CN213731047U. The main improvement of the utility model is that the user can replace the polishing wheel 5 more quickly, further improving the polishing operation efficiency, such as Figures 1 to 4As shown, when the polishing device for the production of unmanned aerial vehicle tripods in the utility model is in use, the polishing wheel 5 is installed on the mounting rod 4, and then the clamping assembly drives the clamping block 7 to rest on the other side of the polishing wheel 5 through the clamping rod 6, and cooperates with the mounting rod 4 to clamp and fix the polishing wheel 5, and then the power assembly is started to drive the mounting rod 4 to rotate, so that the polishing wheel 5 rotates for polishing and grinding operations. During rotation, the clamping block 7 rotates between the bearing and the clamping rod 6. When the polishing wheel 5 needs to be replaced, the clamping rod 6 drives the clamping block 7 to move away from the polishing wheel 5, so that the polishing wheel 5 can be removed from the mounting rod 4, thereby completing the rapid replacement of the polishing wheel 5 and further improving the efficiency of the polishing operation.

[0024] like Figure 1 - Figure 4 As shown, a mounting block 8 is fixedly connected to one end of the mounting rod 4 close to the polishing wheel 5, and a mounting hole 501 matching the mounting block 8 is provided through the center of the polishing wheel 5, and the mounting block 8 is slidably connected to the mounting hole 501. When the polishing wheel 5 is mounted on the mounting rod 4, the polishing wheel 5 can be sleeved on the mounting block 8 through the mounting hole 501, so that the replacement and installation of the polishing wheel 5 can be completed quickly.

[0025] like Figure 4 As shown, the side of the clamping block 7 close to the polishing wheel 5 is provided with a matching hole 701 matching with the mounting block 8, and the mounting block 8 passes through the mounting hole 501 and is slidably connected with the matching hole 701. The matching hole 701 is provided on the clamping block 7, and when the mounting block 8 is against the outside of the polishing wheel 5, the matching hole 701 is sleeved on the mounting block 8, so that when the mounting rod 4 rotates, the polishing wheel 5 and the clamping block 7 can be driven to rotate at the same time, and the slippage of the connection between the clamping block 7 and the polishing wheel 5 can be avoided, so that the polishing wheel 5 can be more stable when rotating at high speed for grinding and polishing.

[0026] like Figure 3 and Figure 4 As shown, the mounting block 8 is designed to be non-circular. Designing the mounting block 8 to be non-circular can prevent the mounting block 8 and the polishing wheel 5 from idling when rotating, and ensure that the polishing wheel 5 can be driven to rotate by the mounting rod 4 more stably.

[0027] like Figure 1 - Figure 4As shown, the power assembly includes a rotating motor 9 and a fixing seat 10, the output shaft of the rotating motor 9 is fixedly connected to the end of the mounting rod 4 away from the polishing wheel 5, the rotating motor 9 is fixedly connected to the fixing seat 10, and the fixing seat 10 is fixedly connected to the power bracket 2. The rotating motor 9 drives the mounting rod 4 to rotate, thereby achieving the purpose of driving the polishing wheel 5 to rotate and polish, and at the same time, the rotating motor 9 is installed on the power bracket 2 through the fixing seat 10, so that when the power bracket 2 is installed and moved, the mounting rod 4 and the power assembly maintain the overall structure unchanged.

[0028] like Figure 1 - Figure 4 As shown, the clamping assembly includes a clamping spring 11 and a baffle 12. The end of the clamping rod 6 away from the polishing wheel 5 passes through the clamping bracket 3 and the clamping spring 11 in sequence and is fixedly connected to the baffle 12. The two ends of the clamping spring 11 are respectively fixedly connected to the baffle 12 and the clamping bracket 3. During installation, the clamping rod 6 is pushed outward, and the polishing wheel 5 is installed on the installation block 8. Then the clamping rod 6 is released, the clamping spring 11 retracts, and the clamping rod 6 is driven to move toward the polishing wheel 5 through the baffle 12, and finally the clamping block 7 is pressed against the polishing wheel 5, completing the installation and fixation of the polishing wheel 5. The disassembly operation is reversed.

[0029] like Figure 1 - Figure 4 As shown, the top of the inner wall of the operating table 1 is fixedly connected with a lifting cylinder 13, the output end of the lifting cylinder 13 is fixedly connected with a connecting plate 14, and both ends of the connecting plate 14 are fixedly connected with lifting rods 15, and the ends of the two lifting rods 15 away from the connecting plate 14 both penetrate the top of the operating table 1, and are respectively fixedly connected with the power bracket 2 and the clamping bracket 3. When using the polishing wheel 5 to grind and polish the drone, especially the polishing of the drone's tripod, since most drone tripods have curved angles, welding angles, etc., the power bracket 2 and the clamping bracket 3 can be lifted upward by the lifting cylinder 13, the connecting plate 14 and the two lifting rods 15, so that the space between the polishing wheel 5 and the operating table 1 is increased, which is convenient for the drone tripod to be mounted on the operating table 1 and contact the polishing wheel 5 above for polishing, further improving the applicability of the polishing device.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
