Technical Field

[0001] This utility model relates to the technical field of drilling devices, and in particular to a drilling device for aerospace components. Background Technology

[0002] Aerospace components are key parts used in spacecraft and aircraft, covering multiple parts such as engines, fuselages, avionics systems, fuel systems, landing gear, and propulsion systems.

[0003] Currently, drilling of aerospace components typically involves using a motor to drive a drill bit to drill holes in the fixed component. For example, Chinese patent document CN219725458U discloses a drilling device for aerospace component production, including a frame and a vibrating base plate. A vertical motor is located on the top right side of the frame, and a drill bit is fixedly installed at the lower output end of the vertical motor. A hydraulic telescopic chamber is fixedly installed on the top surface of the vibrating base plate, and the telescopic end of the bottom surface of the hydraulic telescopic chamber is fixedly connected to the top of the vertical motor. Vertical vibration devices are fixedly installed on both sides of the vibrating base plate, and a condensing device that can cool the drilling device is fixedly installed on the top left side of the frame. Positioning devices are fixedly installed on both sides of the inner wall of the frame. The beneficial effects of this utility model are: by driving the drill bit to vibrate through the vertical vibration device, the problem of the drill bit easily sticking to the part is solved; by cooling the part through the condensing device, the problem of the part easily generating a hardened layer due to high temperature during drilling is solved; and by clamping the part through the positioning device, the problem of the part easily deforming during processing is solved.

[0004] Although the above-mentioned device can drill holes in parts, in actual operation, the parts need to be fixed with a clamp before drilling, and after drilling, the parts need to be disassembled and replaced with the next set of parts to be processed. These fixing and disassembly steps are time-consuming and laborious, which slows down the processing progress of parts and reduces the processing efficiency. Utility Model Content

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The drilling device for aerospace components according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] The aerospace component drilling device provided in this embodiment can be applied to the drilling process of components, eliminating the need for component fixing and disassembly, greatly reducing the time spent in this process, and thus improving the component processing efficiency.

[0023] like Figures 1-3 As shown, the aerospace component drilling device of this utility model embodiment may include a fixing frame 1, a drilling fixing mechanism 2, and a clamping adjustment mechanism 3.

[0024] It should be noted that the fixing frame 1 described in the above embodiment is arranged in a U-shape structure when viewed from both sides.

[0025] The punching and fixing mechanism 2 is mounted on the fixing frame 1. The punching and fixing mechanism 2 may include a lifting component 21, a punching component 22, and a fixing component 23.

[0026] It should be noted that the lifting component 21 described in the above embodiments can be a hydraulic cylinder.

[0027] The lifting assembly 21 is connected to the fixed frame 1, the punching assembly 22 is installed on the fixed assembly 23, and the fixed assembly 23 is connected to the extended end of the lifting assembly 21.

[0028] Understandably, the lifting component 21 is used to raise and lower the height of the drilling component 22 and the fixing component 23. When descending, the fixing component 23 abuts against the clamping adjustment mechanism 3 to fix the aerospace parts. At the same time, the continuous descent of the drilling component 22 is used to open holes in the fixed parts.

[0029] The clamping adjustment mechanism 3 may include an adjustment component 31 and a clamping component 32.

[0030] It should be noted that the adjustment component 31 described in the above embodiment is a screw and a rocker wheel. The screw rotates under the rotation of the rocker wheel, thereby completing the adjustment of the distance between the clamping components 32.

[0031] The adjusting component 31 is rotatably mounted on the fixed frame 1, the clamping component 32 is slidably connected to the adjusting component 31, and the clamping component 32 is located below the fixed component 23.

[0032] Specifically, the adjustment component 31 adjusts the two sets of spacing between the clamping components 32, and then the cooperation between the fixing component 23 and the clamping component 32 completes the fixation of the parts on the fixing frame 1.

[0033] Specifically, in actual operation, when drilling holes in aerospace components, personnel first adjust the distance between clamping components 32 using adjusting component 31 according to the component's dimensions. Then, the component is placed on the fixed frame 1. Under the action of lifting component 21, the positions of drilling component 22 and fixing component 23 are adjusted. As drilling component 22 and fixing component 23 continue to descend, fixing component 23 contacts clamping component 32 first and presses clamping component 32 down to fix the component. Subsequently, fixing component 23 is continuously pressed by lifting component 21, resulting in a contraction effect. As lifting component 21 descends, drilling component 22 contacts the fixed component, thus completing the drilling effect. This eliminates the steps of fixing and disassembling components, significantly reducing the time spent in this process and improving component processing efficiency.

[0034] In one embodiment of this utility model, such as Figures 1-3 As shown, the drilling assembly 22 may include a drive motor 221 and a drill bit 222.

[0035] It should be noted that the drill bit 222 described in the above embodiments can be replaced according to the diameter of the hole in the component.

[0036] The drive motor 221 is mounted on the fixed component 23, and the output end of the drive motor 221 is connected to the drill bit 222.

[0037] Specifically, under the action of the drive motor 221, the drill bit 222 rotates, and then the drill bit 222 contacts the component and completes the hole opening effect.

[0038] In one embodiment of this utility model, such as Figures 1-3 As shown, the fixing component 23 may include a mounting bracket 231, a telescopic rod 232, an abutment spring 233, and an abutment rod 234.

[0039] It should be noted that the fixing component 23 described in the above embodiment is provided in two sets, and a rubber plate is installed at the bottom end of the abutment rod 234 to increase the friction between the abutment rod 234 and the clamping component 32, thereby improving the clamping effect of the clamping component 32.

[0040] The mounting bracket 231 is connected to the extended end of the lifting assembly 21. The telescopic rod 232 is mounted on the mounting bracket 231. The abutment spring 233 is connected to the telescopic rod 232, and one end of the abutment spring 233 is connected to the abutment rod 234. The abutment rod 234 is slidably connected to the telescopic rod 232.

[0041] Specifically, under the action of the mounting bracket 231, the telescopic rod 232 is connected to the lifting assembly 21. Then, the lifting assembly 21 drives the mounting bracket 231 to descend. As the mounting bracket 231 descends, the abutment spring 233 contracts, which causes the abutment rod 234 to contract in the telescopic rod 232. After the abutment rod 234 contacts the adjusting assembly 31, the effect of fixing the parts is completed.

[0042] In one embodiment of this utility model, such as Figures 1-3 As shown, the clamping assembly 32 may include a hinge block 321, a clamping rod 322, a return spring 323, a slider 324, and a limiting block 325.

[0043] It should be noted that the two sets of sliders 324 described in the above embodiments move in opposite directions when they move on the adjustment component 31.

[0044] The slider 324 is threaded onto the outside of the adjusting assembly 31, the limiting block 325 is installed at the bottom of the slider 324, and the fixing frame 1 has a sliding groove for the limiting block 325 to slide. The hinge block 321 is installed on the slider 324, the clamping rod 322 is hinged to the hinge block 321, and the clamping rod 322 is connected to the slider 324 through the return spring 323.

[0045] Specifically, as the adjusting component 31 rotates, the slider 324 adjusts the position of the hinge block 321 and the clamping rod 322 accordingly. The limiting block 325 restricts the movement of the slider 324. The clamping rod 322 is lowered by the abutment of the abutment rod 234, thus fixing the component. When the hole is opened, the clamping rod 322 resets under the action of the return spring 323.

[0046] In one embodiment of this utility model, such as Figures 1-3 As shown, a partition plate is installed in the middle of the adjustment component 31, and threads are provided at both ends of the adjustment component 31, with the two sets of threads arranged in opposite structures.

[0047] Understandably, the partition plate helps prevent the two sets of sliders 324 from colliding.

[0048] In summary, the aerospace component drilling device of this utility model eliminates the steps of fixing and disassembling components, greatly reducing the time spent in this process and thus improving the efficiency of component processing.
