Description

Technical Field

[0001] This utility model relates to the field of strength testing technology, specifically a modular unmanned aerial vehicle (UAV) component strength testing device and method. Background Technology

[0002] With the advancement and development of technology, the research and development of drones is also constantly evolving. Drones are short for unmanned aerial vehicles, which are unmanned aircraft controlled by radio remote control equipment and their own program control devices. In order to ensure the safety of drones during flight, there are certain requirements for the strength of each component during the manufacturing process of drones. Therefore, it is necessary to test each component through strength testing devices.

[0003] However, in actual use, drone parts have different shapes, and commonly used clamping blocks are difficult to clamp drone parts well, resulting in poor positioning of drone parts. At the same time, the positioning and clamping operation is cumbersome during the inspection of drones, which affects the inspection efficiency.

[0004] Existing technology, patent publication number CN110815279, discloses a mechanism for gripping annular parts of different inner diameters, including an annular clamping seat. The bottom surface of the clamping seat has multiple radially distributed clamping grooves along its circumference. Each clamping groove contains a slidably fitted gripper assembly. Each gripper assembly has multiple grippers arranged radially. The spacing between the grippers is greater than the radial thickness of the annular part. A radially telescopic hydraulic cylinder is provided for each gripper assembly. The fixed end of the hydraulic cylinder is mounted on the clamping seat. The telescopic end of the hydraulic cylinder drives the gripper assembly to slide along the clamping grooves. However, the application scenarios of the gripper assembly in this prior art are limited. Summary of the Invention

[0005] The technical problem to be solved by this invention is to address the issues of complex positioning and clamping operations and difficulty in effectively clamping UAV parts by the clamping blocks in the prior art, which affects the detection efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A modular unmanned aerial vehicle (UAV) component strength testing device, comprising:

The first reset groove is connected to the first slide groove, and the second reset groove is connected to the second slide groove.

[0009] A support column is located between two reset slots, and one end of it is fixedly connected to the worktable.

[0010] One end of the push rod is fixedly connected to the other end of the support column;

[0011] A reset component is located below the push rod and is fixedly connected to the other end of the push rod;

[0054] The reset component is inserted into the first reset slot and the second reset slot, and the reset device is pressed down;

[0055] The rack moves downward, releasing the sliding block from engagement, and the second spring resets the moving block.

[0056] Compared with the prior art, the beneficial effects of the present invention are:

[0057] 1. By using the bonding block and the third spring, the bonding block can be bonded to different parts to be tested, as well as to different positions of the same part, thus improving the clamping effect.

[0058] 2. The second oblique cut surface is at the opposite oblique cut position to the first oblique cut surface. The limiting rod swings within the first and second blocking rods with the fixed member as the moving point. When the moving block is pushed to move the sliding block, the limiting rod swings inward towards the second blocking rod, causing the limiting rod to move to the next interval. When the moving block is stopped, the limiting rod is limited within two adjacent ratchet teeth, maintaining the state in which the moving block clamps the part.

[0059] 3. After the strength test is completed, the reset component presses the connecting plate, causing the rack to move downwards, so that the limit rod is disengaged from the ratchet limit. Under the action of the second spring, the moving block is reset, releasing the clamping of the moving block on the tested part. This achieves automatic release of the limit on the UAV part after the test is completed, thereby improving the testing efficiency.

[0060] 4. This invention enables rapid positioning and clamping of UAV parts, and can automatically release the limit on the UAV parts after the inspection is completed, thereby improving inspection efficiency. Attached Figure Description

The moving block 610 drives the sliding block 620 to move, causing the limiting rod 625 to slide on the rack 650. Finally, the fitting block 615 is fitted with different parts of the part to be tested and clamps the part to be tested. The moving block 610 is then stopped. At this time, the fitting block 615 is kept in a clamped state by limiting the limiting rod 625 in two adjacent ratchet teeth 652. After the part to be tested is clamped, the push rod 300 is activated, causing the reset member 400 and the detection device 500 to move downward, so that the detection device 500 can perform strength testing on the part to be tested. After the strength test of the tested part is completed, the push rod 300 continues to push the reset piece 400 downward. At this time, the first telescopic rod 451 and the first spring 452 retract, causing the reset piece 400 to continue to move downward. The reset piece 400 inserts into the first reset groove 130 and the second reset groove 140, and presses the connecting plate 720. The connecting plate 720 drives the rack 650 to move downward, causing the limit rod 625 to disengage from the limit of the ratchet 652. Under the action of the second spring 640, the moving block 610 is reset, thus separating the mating block 615 from the tested part and achieving automatic reset.
