Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), in particular to an assembly jig for propeller clamps of UAVs. Background Art

[0002] As people's living standards improve, drones are becoming increasingly commonplace in all aspects of life. A drone consists of a flight platform, powertrain, control system, navigation, and safety systems. The propellers on a drone provide power for the aircraft and are key components of the powertrain.

[0003] In the prior art, a paddle clamp includes a mounting clamp, a left paddle blade, and a right paddle blade. The mounting clamp includes an upper clamp and a lower clamp. The upper clamp and the lower clamp are clamped together, and the left and right paddle blades are connected to the left and right paddle blades respectively on the left and right sides via a rotating shaft. The left and right sides of the lower clamp are also provided with a circle of positioning grooves, and the positioning grooves are provided with an expansion positioning groove and a storage positioning groove. The left and right paddle blades can rotate freely around the rotating shaft, and the blades are expanded by the centrifugal force generated by the high-speed rotation of the paddle clamp. Currently, most paddle clamps on the market require manual assembly. During manual assembly, the alignment between the upper clamp, the lower clamp, and the left and right paddle blades is inconvenient, the assembly speed is slow, and the production efficiency of the product is reduced. This cannot meet the increasingly high requirements of modern industry and production for paddle clamp assembly.

[0004] Therefore, the existing technology needs to be improved and enhanced. Utility Model Content

[0034] Example:

[0035] like Figure 1-3 As shown, the present application provides a drone propeller clamp assembly jig, comprising a positioning platform 10 and four ejector pins 20 cooperating with the positioning platform 10, the four ejector pins 20 being opposite to each other in pairs, and the positioning platform 10 being provided with two first positioning grooves 11 for positioning the mounting clamp, the bottom of the first positioning groove 11 being relatively provided with two first positioning columns 111 for placing the lower clamp corresponding to the ejector pins, and the two sides of the first positioning groove 11 being relatively provided with a second positioning groove 12 for placing the left blade and a third positioning groove 13 for placing the right blade. Through the above-mentioned structural design, the mutual cooperation between the positioning platform and the ejector pins can increase the speed of assembling the drone propeller clamp and improve the production efficiency of the product.

[0036] When the present invention is working, the lower clamp is first placed in the first positioning groove 11. Since two first positioning posts 111 are provided in the first positioning groove 11, the lower clamp is fixed on the two first positioning posts 111 of the first positioning groove 11. Then the left blade and the right blade are placed in the second positioning groove 12 and the third positioning groove 13 respectively, and then the upper clamp is placed in the first positioning groove 11. Finally, the ejector pin 20 moves toward the positioning platform 10 to assemble the lower clamp, the upper clamp and the left and right blades together through the connecting piece.

[0037] Specifically, the positioning platform 10 is arranged on a lower template 30, the ejector pin 20 is arranged on a fixed plate 50, and the fixed plate 50 is arranged on the upper template 40. A first guide column 31 is provided on each of the four corners of the lower template 30, and a first guide sleeve 41 is provided on each of the four corners of the upper template 40. The first guide column 31 makes a linear reciprocating motion in the corresponding first guide sleeve 41. The first guide column 31 on the lower template 30 cooperates with the first guide sleeve of the upper template 40 to ensure precise alignment and smooth movement of the upper template 40 and the lower template 30, thereby improving the performance and reliability of the entire fixture.

[0038] Specifically, a second guide column 51 is provided on each of the four corners of the fixed plate 50, and a second guide sleeve 14 is provided on each of the four corners of the positioning platform 10. The second guide column 51 cooperates with the corresponding second guide sleeve 14. When the upper template 40 moves toward the positioning platform 10, the second guide column 51 is inserted into the corresponding second guide sleeve 14, further ensuring the precise alignment of the fixed plate 50 and the positioning platform 10.

[0039] Specifically, a movable plate 60 is provided on the side of the fixed plate 50 facing the positioning platform 10, and four connecting rods 52 pass through the fixed plate 50 and are connected to the movable plate 60. A connecting rod 52 is provided between two adjacent second guide columns 51, and the connecting rod 52 is a light rod bolt. A spring 53 is provided on the connecting rod 52 between the fixed plate 50 and the movable plate 60. When the fixed plate 50 moves with the upper template 40, the second guide column 51 on the fixed plate 50 is inserted into the second guide sleeve 14 on the positioning platform 10, the movable plate 60 contacts the positioning platform 10, and the fixed plate 50 continues to move. Since a spring 53 is provided between the fixed plate 50 and the movable plate 60, the fixed plate 50 applies a force on the movable plate 60 through the spring 53, thereby playing a buffering role.

[0040] Specifically, a support platform 15 adapted to the inclined surface of the blade is provided in each of the second positioning groove 12 and the third positioning groove 13. The two support platforms 15 are in opposite directions and are used to adapt to and support the blade to prevent the blade from being installed upside down.

[0041] Specifically, a second positioning column 16 is provided at each of the four corners of the positioning platform 10 near the second guide sleeve 14 , and a positioning hole 61 is provided on the movable plate 60 to cooperate with the second positioning column 16 for accurately positioning the movable plate 60 .

[0042] In summary, the present invention solves the deficiencies in the prior art through the above-mentioned structural design, and has the characteristics of reasonable structure, high efficiency, and high speed.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
