Technical Field
[0001] This utility model relates to the field of drilling technology for structural components of aviation equipment, and in particular to a drilling device for structural components of aviation equipment. Background Technology
[0002] Structural components of aviation equipment are key parts that form the skeleton and shape of aircraft such as airplanes and helicopters. They mainly include wing spars, fuselage frames, and landing gear support structures. By withstanding aerodynamic forces, inertial forces, and internal structural forces during flight, they ensure the overall strength, rigidity, and stability of the aircraft. Their design and manufacturing integrate technologies from multiple disciplines such as aerospace, materials science, and mechanical engineering. They require the use of advanced materials such as high-strength, low-density titanium alloys, aluminum alloys, and composite materials, and employ precision processes such as CNC machining and additive manufacturing to meet stringent requirements for lightweighting, high reliability, and long service life. They play a decisive role in improving the safety and performance of aviation equipment, and drilling is required during production.
[0003] Existing drilling devices for aerospace equipment structural components typically use a fixed-height platform or simple bolts and nuts for height adjustment, making it difficult to quickly and accurately adjust the height according to structural components of different thicknesses. Furthermore, most existing drilling devices have relatively fixed mounting positions; even those with some mobility often rely on manual movement or complex mechanical transmission mechanisms, hindering rapid and convenient position adjustments. Therefore, we propose a drilling device for aerospace equipment structural components. Utility Model Content
[0004] The purpose of this invention is to provide a drilling device for structural components of aerospace equipment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for structural components of aviation equipment, comprising an operating table and a fixing mechanism. A drilling mechanism is provided above and below the operating table. The fixing mechanism includes a carrying plate and four sets of hydraulic telescopic rods. Threaded columns are slidably connected to the four corners of the carrying plate. Limiting nuts are threadedly connected to the outer wall of the threaded columns. Each of the four sets of hydraulic telescopic rods is connected to a sliding block through a fixing frame. Each fixing frame is connected to a threaded rod and a limiting pad through a threaded hole.
[0006] As a preferred embodiment, the upper surface of the operating table is provided with sliding grooves around the center, and mounting holes are provided through the upper surface of the operating table near the outer corners of the center.
[0007] As a preferred embodiment, the threaded post is fixedly installed inside the mounting hole, and the limiting nut is located at the lower end of the carrier plate.
[0008] As a preferred embodiment, the four sets of hydraulic telescopic rods are respectively fixedly installed on the outer walls of the operating platform. One side of the fixing frame is fixedly installed on the output end of the hydraulic telescopic rod. The upper end of the sliding block is fixedly installed on the bottom of the fixing frame. The sliding block is slidably connected inside the sliding groove. The threaded hole penetrates through both sides of the fixing frame. The threaded rod is threadedly connected inside the threaded hole. The limiting pad is sleeved on the inner end of the threaded rod.
[0009] As a preferred embodiment, the drilling mechanism includes a frame and a debris collection box. The bottom of the frame is fixedly installed on the four corners of the operating table surface, and a drilling section is fixedly installed in the middle of the frame.
[0010] As a preferred embodiment, the debris collection box is located directly below the operating table, a filter screen is snapped into the center of the debris collection box, and a vacuum cleaner is fixedly installed at the bottom of the debris collection box, with the air inlet of the vacuum cleaner overlapping the filter screen.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] 1. Through the set fixing mechanism, the load plate is connected to the operating table through the threaded column. With the help of the limit nut, the height of the load plate can be flexibly adjusted according to the thickness of the aerospace equipment structural components, so as to achieve stable bearing of structural components of different specifications. The cooperation of four sets of hydraulic telescopic rods, sliding blocks and sliding grooves allows the fixing frame to slide conveniently along the surface of the operating table and quickly adjust its position to adapt to structural components of different specifications. At the same time, the design of the threaded rod and the limit pad can adjust the clamping force on the structural components, ensuring the fixing effect while avoiding damage to the structural components due to excessive clamping, which significantly improves the flexibility and efficiency of fixing.

This stable structural design allows the drilling section to remain stable when drilling holes in the structural parts of aerospace equipment, reducing drilling errors caused by shaking. The air inlet of the dust extraction fan coincides with the filter screen, and the powerful suction can promptly suck fine debris and dust into the debris collection box, achieving efficient collection of debris and preventing debris from scattering in the work area, thus improving the convenience and cleanliness of the work. The filter screen snapped in the box can effectively intercept larger debris particles, preventing them from entering the dust extraction fan and causing blockage. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see the appendix Figure 1 - Appendix Figure 6 A drilling device for structural components of aviation equipment includes an operating table 1 and a fixing mechanism 4. A drilling mechanism 5 is arranged above and below the operating table 1. The fixing mechanism 4 includes a carrying plate 401 and four sets of hydraulic telescopic rods 404. Threaded columns 402 are slidably connected to the four corners of the carrying plate 401. Limiting nuts 403 are threadedly connected to the outer wall of the threaded columns 402. Each of the four sets of hydraulic telescopic rods 404 is connected to a sliding block 406 through a fixing frame 405. Each fixing frame 405 is connected to a threaded rod 408 and a limiting pad 409 through a threaded hole 407.
[0025] The loading plate 401 can slide up and down along the four sets of threaded posts 402 to adapt to aviation equipment structural components of different heights. The lower limit nut 403 can quickly limit the movement, which facilitates quick operation of aviation equipment structural components of different specifications.
[0026] The upper surface of the control panel 1 has sliding grooves 3 around the center, and mounting holes 2 are provided at the outer corners of the four corners near the center of the upper surface of the control panel 1.
[0027] The sliding groove 3 and mounting holes 2 on the surface of the operating table 1 provide stable guidance and support for the installation and movement of the fixing mechanism 4. The mounting holes 2 are used to fix the threaded post 402, making the installation of the carrier plate 401 more stable. The cooperation between the sliding groove 3 and the sliding block 406 ensures that the fixing frame 405 remains stable during movement, reducing shaking and ensuring drilling accuracy. This design not only facilitates the assembly and disassembly of the device but also adapts to the installation requirements of various aerospace equipment structural components, improving the device's versatility and adaptability.
[0028] The threaded column 402 is fixedly installed inside the mounting hole 2. The limiting nut 403 is located at the lower end of the carrying plate 401. Four sets of hydraulic telescopic rods 404 are fixedly installed on the outer walls of the operating table 1. One side of the fixing frame 405 is fixedly installed at the output end of the hydraulic telescopic rod 404. The upper end of the sliding block 406 is fixedly installed at the bottom of the fixing frame 405. The sliding block 406 is slidably connected inside the sliding groove 3. The threaded hole 407 passes through both sides of the fixing frame 405. The threaded rod 408 is threadedly connected inside the threaded hole 407. The limiting pad 409 is sleeved on the inner end of the threaded rod 408.
[0029] The limiting pad 409 is sleeved with the threaded rod 408, so that when the threaded rod 408 rotates, the limiting pad 409 can keep it from changing its angle. The limiting pad 409 can be replaced according to different specifications of aerospace equipment structural parts to ensure stable clamping.
[0030] Specifically, the loading plate 401 is connected to the operating table 1 via threaded post 402. With the help of the limiting nut 403, the height of the loading plate 401 can be flexibly adjusted according to the thickness of the aerospace equipment structural components, so as to achieve stable bearing of structural components of different specifications. The cooperation of four sets of hydraulic telescopic rods 404 with sliding block 406 and sliding groove 3 allows the fixing frame 405 to slide conveniently along the surface of the operating table 1 and quickly adjust its position to adapt to structural components of different specifications. At the same time, the design of threaded rod 408 and limiting pad 409 can adjust the clamping force on the structural components, ensuring the fixing effect while avoiding damage to the structural components due to excessive clamping, which significantly improves the flexibility and efficiency of fixing.
[0031] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 7and attached Figure 8 The drilling mechanism 5 includes a frame 501 and a debris collection box 503. The bottom of the frame 501 is fixedly installed on the four corners of the surface of the operating table 1, and the drilling part 502 is fixedly installed in the middle of the frame 501.
[0032] The drilling section 502 is existing technology and can precisely drill holes in aerospace equipment structural components of different specifications.
[0033] The debris collection box 503 is located directly below the operating table 1. A filter screen 504 is snapped into the center of the inside of the debris collection box 503. A vacuum cleaner fan 505 is fixedly installed at the bottom of the debris collection box 503. The air inlet of the vacuum cleaner fan 505 coincides with the filter screen 504.
[0034] The filter 504 is snapped into the inside of the debris collection box 503, allowing for removal, cleaning, or replacement when clogged. The vacuum exhaust fan 505 effectively removes dust generated during the drilling process, improving air quality in the working environment, reducing the risk of dust inhalation for operators, and protecting their health. Simultaneously, it prevents dust from flying in the work area, reducing safety hazards such as dust explosions, creating a safer and healthier working environment, and facilitating the continuous and stable operation of drilling work.
[0035] Specifically, the bottom of the frame 501 is fixedly installed at the four corners of the operating table 1, forming a stable support structure, which provides a solid installation foundation for the drilling part 502. This stable structural design allows the drilling part 502 to remain stable when drilling holes in the structural parts of aerospace equipment, reducing drilling errors caused by shaking. The air inlet of the dust extraction fan 505 overlaps with the filter screen 504, and can use strong suction to promptly suck fine debris and dust into the debris collection box 503, achieving efficient collection of debris, preventing debris from scattering in the work area, and improving the convenience and cleanliness of the work. The filter screen 504 snapped into the box can effectively intercept larger debris particles, preventing them from entering the dust extraction fan 505 and causing blockage.
[0036] Working principle of this utility model: This utility model is a drilling device for structural components of aviation equipment. Based on the thickness of the structural component, the limiting nut 403 is rotated to allow the carrier plate 401 to slide up and down along the threaded post 402. After adjusting to the appropriate height, the limiting nut 403 is tightened to securely fix the carrier plate 401 onto the threaded post 402 within the mounting hole 2. Before the actual operation, the dust extraction fan 505 located directly below the bottom of the debris collection box 503 is turned on to ensure it is operational and ready to collect the debris and dust generated during drilling. The structural component of the aviation equipment is then placed stably on the carrier plate 401 and roughly adjusted to the expected drilling position. Position the hydraulic telescopic rod 404 fixedly installed on the outer wall of the operating table 1. The hydraulic telescopic rod 404 drives the fixing frame 405, causing the sliding block 406 at the bottom of the fixing frame 405 to slide in the sliding groove 3 around the center of the upper surface of the operating table 1. Adjust the fixing frame 405 to a suitable position, aligning the circular limiting pad 409 with the part of the structural component that needs to be fixed. Rotate the threaded rod 408 that passes through the threaded holes 407 on both sides of the fixing frame 405, pushing the circular limiting pad 409 sleeved on the inner end of the threaded rod 408 closer to the structural component until the structural component is firmly clamped, ensuring that the structural component will not shift during drilling. Open the fixed installation in the frame 501. The drilling section 502 is configured with appropriate parameters such as rotation speed and feed rate according to the drilling requirements of the aerospace equipment structural components. The drilling section 502 is then activated to drill holes in the structural components. During the drilling process, the working status of the drilling section 502 and the fixation of the structural components are closely observed. If necessary, the position of the fixing bracket 405 is finely adjusted by adjusting the hydraulic telescopic rod 404, or the clamping force of the circular limit pad 409 is adjusted by rotating the threaded rod 408 to ensure drilling accuracy. During the drilling process, the generated debris and dust fall into the debris collection box 503 directly below the operating platform 1 due to gravity. The filter screen 504 is clipped into the center of the debris collection box 503. To intercept larger particles of debris, the vacuum cleaner 505, once turned on, uses its powerful suction to draw fine debris and dust through the filter 504 into the debris collection box 503, achieving efficient collection. After drilling is completed, first close the drilling section 502 to stop drilling, then turn off the vacuum cleaner 505 to end debris collection. Rotate the threaded rod 408 in the opposite direction to loosen the circular limit pad 409, retract the hydraulic telescopic rod 404, remove the fixing frame 405, and take out the drilled aerospace equipment structural component from the carrying plate 401. Open the debris collection box 503, take out the filter 504, and clean the filter 504 and the debris collected inside the box to prepare for the next use.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
