[0002] Aviation hydraulic tanks are a crucial component of aircraft hydraulic systems. Their end caps require precise boring to ensure the tank's sealing performance and connection accuracy. The precision of the holes on the end caps directly affects the normal operation of the hydraulic system. Inaccurate hole dimensions or substandard inner wall roughness can lead to problems such as oil leakage and unstable hydraulic system pressure, thereby impacting aircraft flight safety and performance.

[0003] During the boring process, a large amount of debris is generated. Although some existing boring devices have debris removal mechanisms, for smaller holes, the external air blasting structure is insufficient to effectively remove fine debris from the hole. Moreover, some debris falls to the ground, polluting the environment, making cleanup difficult, and potentially affecting the cleanliness of the machining area and subsequent operations.

[0004] Therefore, it is necessary to invent a boring device based on the end cap of an aviation hydraulic tank to solve the above problems. Utility Model Content

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-5 The boring device based on the end cap of the aviation hydraulic oil tank shown includes a boring tool 1, a mounting plate 2 on the outside of the boring tool 1, a plurality of evenly spaced mounting holes 21 on the mounting plate 2, a plurality of nozzle assemblies 3 and chip suction assemblies 4 installed in the plurality of mounting holes 21, and the plurality of nozzle assemblies 3 and chip suction assemblies 4 are arranged alternately. Specifically, the nozzle assembly 3 includes a nozzle 31 and a pipe 32 connected to its tail. The nozzle 31 is also provided with a docking component 33. A docking ring 22 is provided at the bottom of the mounting hole 21. The docking component 33 fixes the nozzle assembly 3 as a whole in the mounting hole 21. Specifically, the dust collection assembly 4 includes a dust collection hopper 41 and a collection pipe 42 connected to its tail. The outer wall of the collection pipe 42 is provided with a positioning block 43, and a matching positioning groove 23 is provided on the inner wall of the corresponding mounting hole 21. The dust collection assembly 4 moves within the mounting hole 21.

[0019] Specifically, the docking assembly 33 includes a positioning ring 331 that matches the docking ring 22. Two sets of symmetrical locking plates 332 are fixed on the outer wall of the positioning ring 331. A telescopic groove 333 is provided on one side of the end of the locking plate 332. A locking block 334 is installed in the telescopic groove 333. The docking ring 22 is provided with multiple locking grooves 24 that match the locking block 334. An unlocking handle 335 is connected to the end of the locking block 334. Multiple compression springs 336 are provided on the upper and lower sides of the unlocking handle 335 at the tail of the locking block 334. The movement of the unlocking handle 335 causes the locking block 334 to disengage from the locking groove 24.

[0020] Specifically, the expansion groove 333 is provided with a limiting frame 338 at the groove opening, which matches the limiting strip 337 on the outer wall edge of the locking block 334. The bottom of the expansion groove 333 is provided with a through hole 339 for the unlocking handle 335. The other end of the compression spring 336 is fixed to the bottom of the expansion groove 333 on both sides above and below the through hole 339.

[0021] Specifically, the unlock handle 335 has a pull hole 3351 inside, and the inner wall of the pull hole 3351 has multiple arc-shaped grooves 3352 on one side. The unlock handle 335 has an arc shape on one side, and the moving surface of the locking block 334 is a slope.

[0022] Specifically, the locking grooves 24 are set on the outer wall of the docking ring 22 and are evenly spaced. The number of locking grooves 24 is greater than the number of locking blocks 334.

[0023] Specifically, an anti-slip section 34 is provided on the outer wall of the nozzle 31 below the docking assembly 33.

[0024] Specifically, the end of the dust collection hopper 41 is bucket-shaped, the outer wall of the collection pipe 42 is provided with a fixed pipe 44, the positioning block 43 is located above the outer wall of the fixed pipe 44, and the bottom of the positioning groove 23 is provided with a limiting plate 25 that matches the positioning block 43.

[0025] In this embodiment, before boring the end cap of the aviation hydraulic oil tank, the installation of each component of the device must be completed first. For the nozzle assembly 3, it is aligned with the mounting hole 21 on the mounting plate 2 and fixed by the docking assembly 33. Specifically, the positioning ring 331 matches the docking ring 22. When the positioning ring 331 is fitted into the docking ring 22, the locking block 334 in the telescopic groove 333 at the end of the locking plate 332 pops out under the action of the compression spring 336 and is locked into the locking groove 24 on the outer wall of the docking ring 22. At this time, the limiting frame 338 at the opening of the telescopic groove 333 cooperates with the limiting strip 337 on the outer edge of the locking block 334 to limit the movement range of the locking block 334 and ensure a stable lock. Since the locking grooves 24 are evenly spaced and the number is greater than the number of locking blocks 334, the angle of the nozzle 31 can be adjusted according to actual needs. Meanwhile, the anti-slip section 34 on the outer wall of the nozzle 31, located below the docking assembly 33, increases the grip stability during installation, making it easier for operators to install and adjust. Specifically, for the dust collection assembly 4, align the collection pipe 42 connected to the tail of the dust collection hopper 41 with the corresponding mounting hole 21, so that the positioning block 43 on the outer wall fixing pipe 44 of the collection pipe 42 matches the positioning groove 23 on the inner wall of the mounting hole 21. Then, insert the dust collection assembly 4 into the mounting hole 21 along the positioning groove 23 until the positioning block 43 contacts the limiting plate 25 at the bottom of the positioning groove 23, thus completing the installation of the dust collection assembly 4. Multiple sets of nozzle assemblies 3 and dust collection assemblies 4 are installed in the mounting holes 21 in an alternating manner to ensure the smooth progress of subsequent operations.

[0026] In this embodiment, during the boring stage, the device is activated, and the boring tool 1 begins boring the end cap of the aviation hydraulic oil tank. During the operation, the nozzle assembly 3 delivers cutting fluid through the pipeline 32 and sprays it onto the boring area through the nozzle 31, which serves to cool and lubricate, reduce friction between the tool and the workpiece, reduce tool wear, and also remove some heat to prevent the workpiece from deforming due to excessive temperature. Specifically, the chip suction assembly 4 begins operation. The bucket-shaped design at the end of the chip suction hopper 41 allows for more efficient collection of chips generated during boring. The chips are then transported to an external collection device via the collection pipe 42. Since the chip suction assembly 4 can move within the mounting hole 21, the operator can adjust the position of the chip suction hopper 41 by moving the assembly along the positioning groove 23, depending on the location of the chips, to ensure effective chip collection.

[0027] In this embodiment, when the boring operation is completed or maintenance of the device is required, each component needs to be disassembled. For the nozzle assembly 3, the operator pulls the pull hole 3351 on the unlocking handle 335. The arc-shaped groove 3352 on one side of the inner wall of the pull hole 3351 facilitates the application of force by the fingers. The movement of the unlocking handle 335 causes the locking block 334 to compress the compression spring 336, causing the locking block 334 to disengage from the locking groove 24. At this time, the nozzle assembly 3 can be removed from the mounting hole 21. The arc shape on one side of the unlocking handle 335 and the inclined surface of the moving surface of the locking block 334 reduce the resistance during operation, making the disassembly process easier. Specifically, for the dust suction assembly 4, it can be simply pulled out from the mounting hole 21 along the positioning groove 23, which is simple and convenient. After disassembly, the nozzle assembly 3 and the dust suction assembly 4 can be cleaned, inspected, and maintained to ensure normal operation in the next operation.

[0028] In this embodiment, multiple sets of nozzle assemblies 3 and chip suction assemblies 4 are staggered, so that the cutting fluid can fully cover the boring area, resulting in significant cooling and lubrication effects and reducing downtime for tool changes due to tool overheating. At the same time, the chip suction assembly 4 can collect chips in a timely and efficient manner, preventing chip accumulation from affecting the boring accuracy and work progress, thereby improving the overall efficiency of boring operations. In this embodiment, the angle of the nozzle assembly 3 can be flexibly adjusted through the cooperation of the locking groove 24 and the locking block 334, ensuring that the cutting fluid is accurately sprayed onto the location requiring cooling and lubrication, reducing workpiece deformation caused by uneven cooling, and ensuring the accuracy of the boring dimensions. The movable design of the chip suction assembly 4 can promptly remove chips generated during the boring process, avoiding collisions between chips and the tool and workpiece, further ensuring the surface quality and accuracy of the boring. In this embodiment, the locking and unlocking structure of the docking component 33 is cleverly designed, allowing for quick installation and disassembly of the nozzle component 3 by pulling the unlocking handle 335; the dust suction component 4 can also be easily installed and disassembled through the cooperation of the positioning block 43 and the positioning groove 23. This convenient operation method reduces the labor intensity of operators and saves time for device installation and maintenance.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
