Description

Technical Field

[0001] This utility model relates to the field of static balance testing technology, and more specifically, to a propeller static balance test bench. Background Technology

[0002] A propeller static balancing test bench is a device used to test and calibrate the balance of a propeller. The propeller plays a crucial role in an aircraft, and it needs to maintain balance during high-speed rotation to ensure the stability and safety of the aircraft. The static balancing test bench is used to detect the mass distribution of the propeller in a static state in order to discover problems with uneven mass distribution of the propeller, and to ensure the balance of the propeller by adjusting the counterweight.

[0003] However, existing propeller static balance testing devices still have some problems in actual use. For example, due to their simple structure, existing static balance testing devices cannot be used to test propellers of different sizes and diameters. In other words, different corresponding equipment needs to be replaced when dealing with different types of propellers, resulting in low practicality of existing propeller static balance testing devices. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a propeller static balancing test bench that overcomes or at least partially solves the above technical problems.

[0005] This utility model is implemented as follows: This utility model provides a propeller static balance test bench, including a main frame, a vertical frame is provided on the top surface of the main frame, a longitudinal adjustment mechanism is provided on the top surface of the vertical frame, and a transverse adjustment mechanism is provided inside the main frame. The longitudinal adjustment mechanism includes a connecting plate, an mounting plate is fixedly installed on the bottom surface of the connecting plate, and an electric telescopic rod is fixedly connected to the top of the mounting plate. The longitudinal adjustment mechanism is designed to adapt to the clamping and detection of propellers of different diameters. The lateral adjustment mechanism includes two rotating shafts, both of which are rotatably installed inside the main frame. One end of each rotating shaft is fixedly connected to a threaded rod, and a snap-fit ​​plate is movably engaged inside the main frame. The other end of the threaded rod is rotatably connected to one side surface of the snap-fit ​​plate. The lateral adjustment mechanism is designed to accommodate the detection of propellers of different lengths.

[0006] In a preferred embodiment, a fixed frame is fixedly connected to the top of the upright, and a snap-fit ​​bracket is movably engaged inside the fixed frame. One end of the electric telescopic rod extends into the interior of the fixed frame and is fixedly connected to the bottom surface of the snap-fit ​​bracket.

[0007] In a preferred embodiment, a top frame is fixedly installed on the top surface of the fixing frame, and a second roller is rotatably installed inside the top frame. Two first rollers are rotatably installed inside the snap-fit ​​frame.

[0008] In a preferred embodiment, a gear is fixedly sleeved on the outer surface of the rotating shaft, and a threaded sleeve is fixedly connected to the bottom surface of one of the uprights, with the threaded rod threadedly sleeved inside the threaded sleeve.

[0009] In a preferred embodiment, a mounting frame is fixedly installed on the top surface of the main frame, a motor is fixedly installed on one side surface of the mounting frame, a second gear is fixedly sleeved on the output end of the motor, and a chain is sleeved on the outer surface of the second gear and the first gear.

[0010] In a preferred embodiment, a limiting frame is fixedly installed inside the main frame, and a limiting plate is fixedly connected to the bottom surface of one of the uprights, the limiting plate being movably engaged inside the limiting frame.

[0011] The propeller static balancing test bench provided by this utility model has the following beneficial effects: 1. By setting up a longitudinal adjustment mechanism, the activation of the electric telescopic rod can drive the clamping frame to move upward inside the fixed frame, thereby gradually reducing the distance between roller one and roller two until roller two clamps and fixes the propeller mounting shaft. Then, the static balance of the clamped and fixed propeller can be tested. Since the distance between the clamping frame and the top frame can be flexibly adjusted, it can be used for testing different propellers, thus greatly increasing the overall practicality of the device.

[0012] 2. By setting a lateral adjustment mechanism, when the motor starts, it can drive the second gear to rotate synchronously, which in turn can drive the rotating shaft to rotate. Since the threaded rod is threaded inside the threaded sleeve, it can drive one of the uprights to move towards the motor at the top of the main frame, thereby realizing the connection between the two uprights. This allows for adjustment to accommodate propellers of different lengths, further increasing the overall practicality of the device. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Reference Figure 1 - Figure 4 This utility model provides a technical solution: a propeller static balance test bench, including a main frame 1, a support frame 3 on the top surface of the main frame 1, a longitudinal adjustment mechanism 4 on the top surface of the support frame 3, a transverse adjustment mechanism 5 inside the main frame 1, and multiple casters 2 installed on the bottom surface of the main frame 1 to improve the overall flexibility of the device. The longitudinal adjustment mechanism 4 includes a connecting plate 401, a mounting plate 402 is fixedly installed on the bottom surface of the connecting plate 401, and an electric telescopic rod 403 is fixedly connected to the top of the mounting plate 402. The longitudinal adjustment mechanism 4 is designed to adapt to the clamping and detection of propellers of different diameters. A fixed frame 404 is fixedly connected to the top of the support frame 3. A snap-fit ​​bracket 405 is movably engaged inside the fixed frame 404. One end of the electric telescopic rod 403 extends into the interior of the fixed frame 404 and is fixedly connected to the bottom surface of the snap-fit ​​bracket 405. A top frame 407 is fixedly installed on the top surface of the fixed frame 404. A second roller 408 is rotatably mounted inside the top frame 407. Two first rollers 406 are rotatably mounted inside the snap-fit ​​bracket 405. When testing the propeller, simply place the propeller's mounting shaft on the top of each of the two first rollers 406. Then, by controlling the start of the electric telescopic rod 403, the clamping frame 405 can be driven to move upward inside the fixed frame 404, thereby gradually reducing the distance between roller 1 406 and roller 2 408 until roller 2 408 clamps and fixes the propeller mounting shaft. Then, the static balance of the clamped and fixed propeller can be tested. Since the distance between the clamping frame 405 and the top frame 407 can be flexibly adjusted, it can be used for testing different propellers, thus greatly increasing the overall practicality of the device.

[0018] The lateral adjustment mechanism 5 includes two rotating shafts 501, both of which are rotatably mounted inside the main frame 1. One end of each rotating shaft 501 is fixedly connected to a threaded rod 503. A locking plate 509 is movably engaged inside the main frame 1. The other end of the threaded rod 503 is rotatably connected to one side surface of the locking plate 509. The lateral adjustment mechanism 5 is designed to accommodate the detection of propellers of different lengths. A gear 502 is fixedly fitted onto the outer surface of the rotating shaft 501. A threaded sleeve 504 is fixedly connected to the bottom surface of one of the uprights 3, and the threaded rod 503 is threadedly fitted inside the threaded sleeve 504. A mounting bracket 505 is fixedly mounted on the top surface of the main frame 1, and a mounting bracket 505 is fixedly mounted on one side surface of the mounting bracket 505. There is a motor 506, and a gear 507 is fixedly sleeved at the output end of the motor 506. A chain 508 is sleeved on the outer surface of the gear 507 and the gear 502. When dealing with a propeller with a large length, the motor 506 can be started by controlling it. When the motor 506 starts, it can drive the gear 507 to rotate synchronously, which in turn drives the rotating shaft 501 to rotate. Since the threaded rod 503 is threaded inside the threaded sleeve 504, it can drive one of the uprights 3 to move towards the motor 506 from the top of the main frame 1. This allows for the connection of the two uprights 3, thus enabling adjustment for propellers of different lengths and further increasing the overall practicality of the device.

[0019] A limiting frame 6 is fixedly installed inside the main frame 1. A limiting plate 7 is fixedly connected to the bottom surface of one of the uprights 3. The limiting plate 7 is movably engaged inside the limiting frame 6. The limiting frame 6 and the limiting plate 7 make the upright 3 more stable when it moves laterally above the main frame 1.

[0020] Specifically, the working process or working principle of this propeller static balance test bench is as follows: In use, the propeller mounting shaft is placed on the top of the two rollers 406. Then, by controlling the start of the electric telescopic rod 403, the clamping frame 405 can be driven to move upward inside the fixed frame 404, thereby gradually reducing the distance between the roller 406 and the roller 408 until the roller 408 clamps and fixes the propeller mounting shaft. The static balance of the propeller after clamping and fixing can then be tested. When the motor 506 starts, it can drive the gear 507 to rotate synchronously, thereby driving the rotating shaft 501 to rotate. Since the threaded rod 503 is threaded inside the threaded sleeve 504, it can drive one of the uprights 3 to move towards the motor 506 from the top of the main frame 1, thereby realizing the connection between the two uprights 3, thus enabling adjustment for propellers of different lengths.

[0021] It should be noted that the motor 506 and the electric telescopic rod 403 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail here.
