Description

Technical Field

[0001] This utility model relates to the field of drone assembly technology, and more specifically, it relates to an assembly tooling for drone production. Background Technology

[0002] Small drones mostly employ multi-rotor or fixed-wing designs, featuring portability, flexibility, and ease of operation. They are widely used in aerial photography, agricultural plant protection, logistics delivery, environmental monitoring, and other fields. Some consumer-grade models also support intelligent following and obstacle avoidance functions. Due to their low cost and high maneuverability, small drones have become the mainstream choice in the civilian and recreational markets.

[0003] Chinese patent document CN221914623U discloses an assembly tooling for drone production that uses a U-shaped clamping seat and a clamping block in combination. Although it can clamp and fix drone parts, its design has obvious limitations.

[0004] First, the enclosed structure of the U-shaped clamp will cover some of the critical areas of the parts to be assembled, affecting the operator's observation and operation of the connection points of the parts during the assembly process, reducing the flexibility and accuracy of the assembly.

[0005] Secondly, the clamping range of this tooling is limited by the opening size of the U-shaped structure, making it suitable only for drone parts within a specific volume range. It cannot meet the assembly needs of drones of different sizes, which is particularly disadvantageous in the scenario of multi-variety, small-batch drone production. In addition, the fixed clamping structure lacks adjustment function, making it difficult to cope with the clamping requirements of complex curved surfaces or irregularly shaped parts, further limiting the versatility of the tooling. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the problems existing in the prior art, this utility model provides an assembly tooling for drone production, thereby solving the technical problem mentioned in the background art of the poor flexibility and convenience of using existing drone production assembly tooling.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An assembly fixture for UAV production includes a workbench with a rotating seat mounted on it. The rotating seat is rotatably mounted on the workbench via a bearing and a shaft. A rotating motor is mounted at the bottom of the workbench and is connected to the rotating seat. A placement seat is mounted on the rotating seat, and support seats are symmetrically arranged on the sides of the placement seat. Each support seat is equipped with a first electric push rod, and a movable frame is mounted on the first electric push rod. Two sets of mounting seats are synchronously and counter-rotatingly mounted on the movable frame, and a second electric push rod is mounted on the mounting seat. A clamping frame is horizontally hinged to the output end of the second electric push rod, and two sets of clamping blocks are symmetrically arranged on the inner side of the clamping frame.

[0011] The present invention is further configured such that a bidirectional ball screw is provided on the movable frame, and a screw nut is assembled with the bidirectional ball screw. A screw motor is provided on the movable frame, and the screw motor is drivenly connected to the bidirectional ball screw. When the screw motor is started, the operation of the bidirectional ball screw can be controlled by the screw motor, so that the two sets of screw nuts move closer or further apart. The mounting seat is set on the corresponding screw nut, thereby controlling the screw nut to drive the mounting seat, the second electric push rod, the clamping frame, the clamping block and other related structures to move and adjust. In this way, the two sets of clamping frames on the same side can move closer or further apart, so as to flexibly clamp and fix the components of different models of UAVs during assembly.

[0012] The present invention is further configured such that a limiting telescopic rod is provided between the support base and the movable frame. The limiting telescopic rod is located on both sides of the first electric push rod and extends and retracts synchronously with the first electric push rod. The setting of the limiting telescopic rod can improve the stability of the movable base during lifting and moving, and assist the first electric push rod to realize the lifting and adjusting of the movable frame.

[0013] The present invention is further configured such that the side of the placement seat is provided with a mounting ear, the support seat is mounted on the mounting ear, and a locking bolt is provided between the mounting ear and the mounting ear. The support seat can be detachably installed on the placement seat by the cooperation of the mounting ear and the locking bolt, so that when different models of placement seats are replaced, they can be used with the same set of clamping frames, thus saving equipment costs.

[0014] The present invention is further configured such that the rotating seat is provided with an installation groove, the bottom end of the placement seat is provided with an installation block, and the bottom end of the installation block and the installation groove are provided with a magnetic locking structure, so that the placement seat can be quickly connected to the rotating seat through the cooperation of the installation groove and the installation block.

[0015] The present invention is further configured such that the magnetic locking structure includes a first magnetic block, which is disposed at the bottom of the mounting groove, and a second magnetic block is disposed at the bottom of the mounting block. The first magnetic block and the second magnetic block are magnetically engaged, and the magnetic engagement between the first magnetic block and the second magnetic block enables the placement seat and the rotating seat to be quickly fixed by magnetic attraction, which facilitates the convenient installation and replacement of the placement seat on the rotating seat, thereby allowing for flexible selection of different models of placement seats for different assembly models of drones.

[0016] The present invention is further configured such that a limiting groove is formed above the side of the mounting groove, and a limiting strip is provided on the side wall of the mounting block. The limiting strip and the limiting groove are slidably engaged. Through the cooperation of the limiting groove and the limiting strip, the rotation of the mounting block in the mounting groove can be limited, thereby improving the installation stability of the placement seat on the rotating seat.

[0017] The present invention is further configured such that the clamping frame has a locking groove, and the back of the clamping block has a locking strip. The locking strip and the locking groove are interference-fitted. The clamping block is preferably made of rubber. In this way, the clamping block can be easily disassembled and replaced on the clamping frame through the cooperation of the locking strip and the locking groove. Since the clamping block made of rubber is a consumable, the ease of replacement of the clamping block is improved.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides an assembly tooling for drone production, which has the following beneficial effects:

[0020] 1. Flexible adjustment in multiple dimensions

[0021] This invention achieves precise adjustment of UAV components in multiple dimensions, including horizontal rotation, vertical lifting, and lateral clamping, through the coordinated design of a rotary motor, a bidirectional ball screw, and first / second electric push rods. The hinged structure of the clamping frame further adapts to irregularly shaped components, solving the problems of view obstruction and operation limitations caused by the fixed structure of traditional tooling, and significantly improving the flexibility and operating space when assembling complex components.

[0022] 2. Modular quick-change

[0023] The use of a magnetic locking structure (first / second magnetic blocks) in conjunction with a limiting groove / strip enables the placement base to be replaced in seconds; meanwhile, the support base is fixed by mounting ears and locking bolts, making it easy to adapt to the production of different drone models. This modular design allows the tooling to quickly respond to the production needs of multi-variety, small-batch production, reducing the cost of repeated equipment investment.

[0024] 3. Adaptive clamping and enhanced stability

[0025] The articulated clamping frame, combined with replaceable rubber clamping blocks (slot / strip structure), can adapt to different curved surface shapes through multi-point contact, while avoiding component damage caused by rigid clamping, ensuring high stability during the clamping process.

[0038] Please see Figures 1-7 As one implementation of the movable frame 7: the movable frame 7 is equipped with a bidirectional ball screw 12, and a screw nut 13 is assembled with the bidirectional ball screw 12. The movable frame 7 is equipped with a screw motor 14, which is connected to the bidirectional ball screw 12. When the screw motor 14 is started, the operation of the bidirectional ball screw 12 can be controlled by the screw motor 14, so that the two sets of screw nuts 13 move closer or further away from each other. The mounting seat 8 is set on the corresponding screw nut 13, so that the screw nut 13 can drive the mounting seat 8, the second electric push rod 9, the clamping frame 10, the clamping block 11 and other related structures to move and adjust. In this way, the two sets of clamping frames 10 on the same side can move closer or further away from each other. In this way, flexible clamping and fixing can be achieved when assembling different models of UAV components.

[0039] Please see Figures 1-7 As one embodiment of the support base 5: a limiting telescopic rod 15 is provided between the support base 5 and the movable frame 7. The limiting telescopic rod 15 is located on both sides of the first electric push rod 6 and extends and retracts synchronously with the first electric push rod 6.

[0041] Please see Figures 1-7 As one embodiment of the rotating seat 2: the rotating seat 2 is provided with an installation groove 18, and the bottom end of the placement seat 4 is provided with an installation block 19. The bottom end of the installation block 19 and the installation groove 18 are provided with a magnetic locking structure. The placement seat 4 can be quickly connected to the rotating seat 2 through the cooperation of the installation groove 18 and the installation block 19.

[0042] Please see Figures 1-7 As one implementation of the magnetic locking structure: the magnetic locking structure includes a first magnetic block 20, which is disposed at the bottom of the mounting groove 18. A second magnetic block 21 is disposed at the bottom of the mounting block 19. The first magnetic block 20 and the second magnetic block 21 are magnetically engaged. The magnetic engagement between the first magnetic block 20 and the second magnetic block 21 enables the placement seat 4 and the rotating seat 2 to be quickly fixed by magnetic attraction, which facilitates the convenient installation and replacement of the placement seat 4 on the rotating seat 2. Thus, different models of placement seats 4 can be flexibly selected according to the assembly model of the UAV.

Since the clamping block 11 made of rubber is a consumable, the ease of replacement of the clamping block 11 is improved.

[0045] In summary:

[0046] When assembling the drone, the components that need to be fixed, such as the frame, are placed on the placement seat 4;

[0047] Start the first electric push rod 6, control the lifting and lowering of the moving frame 7 through the first electric push rod 6, and then control the lifting and lowering of the clamping frame 10 through the transmission cooperation of related components such as the mounting base 8 and the second electric push rod 9, so as to realize the flexible adjustment of the clamping height of the clamping block 11.

[0048] At the same time, the lead screw motor 14 is started, which can control the operation of the bidirectional ball screw 12, so that the two sets of lead screw nuts 13 move closer or further apart. The mounting seat 8 is set on the corresponding lead screw nut 13, so that the lead screw nut 13 can drive the mounting seat 8, the second electric push rod 9, the clamping frame 10, the clamping block 11 and other related structures to move and adjust, thereby enabling the two sets of clamping frames 10 on the same side to move closer or further apart.

[0049] After adjusting to the appropriate position, the second electric push rod 9 is activated. The second electric push rod 9 can control the clamping frame 10 to carry the clamping block 11 to move toward the drone component, thereby clamping and fixing the drone assembly component.

[0050] In this utility model, the clamping frame 10 is horizontally hinged to the output end of the second electric push rod 9. Thus, when the clamping block 11 contacts the side of the drone assembly component, the contact clamping angle can be automatically adjusted according to the shape of the drone assembly component. This can better achieve the clamping and fixing of the drone assembly component during assembly.

[0051] Furthermore, by employing a clamping block 11 structure and cooperating with an arc-shaped clamping frame 10, this utility model enables multi-point fixation of the assembly components of the drone during clamping, thereby improving the stability during assembly.

[0052] During assembly, if it is necessary to adjust the assembly angle, the rotation motor 3 can be started. The rotation motor 3 controls the rotation of the rotating seat 2. The rotation of the rotating seat 2 and the placement seat 4 can be controlled by the limiting cooperation between the rotating seat 2 and the placement seat 4, thereby realizing the rotation adjustment of the drone assembly parts located on the placement seat 4 and improving the convenience of drone assembly.

[0053] In all the solutions mentioned above, the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
