Description

Technical Field

[0001] The present invention relates to the technical field of aviation parts processing, and in particular to a hole boring device and a hole boring method for aviation parts processing. Background Art

[0002] Aviation refers to the flight activities of aircraft in the Earth's atmosphere, as well as related fields such as scientific research and education, industrial manufacturing, public transportation, professional work, aerospace sports, and national defense and military affairs. Through the use of airspace and aircraft, aviation activities can be subdivided into numerous independent industries and fields, such as aviation manufacturing and civil aviation.

[0003] Hole turning is the process of enlarging a workpiece's hole or machining the inner surface of a hollow workpiece using a turning method. Prior to this, hole turning operations on accessories required first using a fixture on a lathe to clamp and secure the accessory. Driven by a driving device, the fixture rotated along with the accessory, and the accessory was then machined through a series of cutting operations, including feed and retract. However, since aviation accessories are often precision instruments, the fixture must be held tightly to prevent them from flying out during rotation and causing safety accidents, yet not too tightly. Furthermore, the force on the accessory must be balanced to prevent excessive compression and deformation of the tightly packed accessory.

[0004] Existing drilling technology makes it difficult to ensure that the forces on all bearing surfaces of an aviation component are balanced and within a safe force range when it is clamped. Furthermore, drilling a row of holes on the same component requires multiple clamping and disassembly operations, which is cumbersome. Summary of the Invention

Implementation Method

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] See also Figures 1 to 10 As shown, specifically Figure 1 As shown, a drilling device for machining aviation parts includes: a console 3, a control assembly 5 fixedly mounted on the side wall of the console 3, and the control assembly 5 is used to control all electrical components of the device. A first slide rail 301 is fixedly mounted on one end surface of the console 3, and a positioning frame 1 is slidably connected to the first slide rail 301. The positioning frame 1 is provided with a clamping mechanism, and the clamping mechanism is used to adjust the position of the clamping mechanism; the clamping mechanism includes a first clamping assembly 2 and a second clamping assembly 6. The second clamping assembly 6 is used to pre-install the aviation part, and the first clamping assembly 2 is used to lock the aviation part.

[0045] The end of the positioning frame 1 away from the console 3 is fixed with a second slide rail 101 and a first drive motor 102. Figure 5 As shown, the first clamping assembly 2 includes a first slider 201 and a second slider 202, the first slider 201 and the second slider 202 are both slidably connected to the second slide rail 101, a threaded hole is opened on the side of the first slider 201 away from the second slider 202, a threaded column 210 is threadedly connected to the threaded hole, and the end of the threaded column 210 away from the first slider 201 is transmission-connected to the first drive motor 102; the positioning frame 1 is also rotatably connected to a first gear 204, a driving rack 203 is vertically fixed to the side wall of the first slider 201, and a driven rack 205 is vertically fixed to the side wall of the second slider 202, the driving rack 203 and the driven rack 205 are parallel to each other, and the first gear 20 4 is located between the driving rack 203 and the driven rack 205, and the driving rack 203 and the driven rack 205 are both engaged with the first gear 204; when the first driving motor 102 is turned on, it drives the threaded column 210 to rotate. Since the first slider 201 is threadedly connected to the threaded column 210, and the second slide rail 101 limits the rotation of the first slider 201, the first slider 201 will slide along the second slide rail 101. At the same time, the driving rack 203 drives the first gear 204 to rotate, indirectly causing the driven rack 205 to move, so that the second slider 202 and the first slider 201 slide synchronously along the second slide rail 101, and the sliding directions are opposite, so that the accessories between the first slider 201 and the second slider 202 can be clamped and locked.

[0046] The first slider 201 and the second slider 202 have opposite side walls with square grooves, and a rotating shaft 2061 is rotatably connected in the square grooves. Figure 6 As shown, a bushing 206 with a polygonal cross-section is fixedly mounted on the rotating shaft 2061, and a plurality of gaskets 2062 are detachably mounted on the sidewalls of the bushing 206. A worm gear 2063 is coaxially fixedly connected to one end of the rotating shaft 2061. A micro motor 209 is fixedly mounted on each of the first and second sliders 201 and 202. The micro motor 209 is transmission-connected to a worm 208, which meshes with the worm gear 2063. Gaskets 2062 of varying hardness can be mounted on the sidewalls of the bushing 206 as needed. Before clamping an aviation accessory, the gasket 2062 that will come into contact with the aviation accessory is adjusted appropriately to protect the bearing surface of the aviation accessory. During operation, the micro motor 209 is activated to rotate the worm 208, which in turn rotates the worm gear 2063 to adjust the surface that will come into contact with the aviation accessory. In addition, since the cross section of the bushing 206 is polygonal, the rotating shaft 2061 can be rotated to adjust the size of the contact surface with the aviation accessory.

[0047] A first hydraulic telescopic rod 207 is fixedly mounted between the first slider 201 and the second slider 202. The second clamping assembly 6 includes an oil control unit 603 and two second hydraulic telescopic rods 602. One end of each second hydraulic telescopic rod 602 is fixedly mounted on the end surface of the positioning frame 1 near the control console 3. A silicone plate 601 is detachably mounted on the other end of each second hydraulic telescopic rod 602. The silicone plate 601 has a low hardness and effectively protects the bearing surface of the aviation component while pre-installing and clamping it.

[0048] The oil control unit 603 includes an oil storage tank, which is fixedly mounted on the end surface of the positioning frame 1. The oil storage tank is provided with an electrically driven hydraulic oil pump 6031. Figure 8 As shown, the hydraulic oil pump 6031 is connected to a three-position four-way electromagnetic reversing valve 6032, the first and second hydraulic telescopic rods are connected to the electromagnetic reversing valve 6032 through oil pipes, and a first electric stop valve 604 is also installed between the second hydraulic telescopic rod 602 and the electromagnetic reversing valve 6032, the first hydraulic telescopic rod 207 and the second hydraulic telescopic rod 602 are connected through oil pipes, and a second electric stop valve 605 is provided between the first hydraulic telescopic rod 207 and the second hydraulic telescopic rod 602.

[0049] A first pressure detector is installed within the cylinder of the first hydraulic telescopic rod 207 and is electrically connected to the hydraulic oil pump 6031. A second pressure detector is installed within the cylinder of the second hydraulic telescopic rod 602 and is electrically connected to both the hydraulic oil pump 6031 and the first electric shut-off valve 604. The first and second detectors are used to detect the oil pressure within the cylinders of the first and second hydraulic telescopic rods 207 and 602, respectively.

[0050] like Figure 2 As shown, the console 3 is connected to a first screw rod 305 that rotates along the direction of the first slide rail 301. The first screw rod 305 is threadedly connected to the positioning frame 1. One end of the first screw rod 305 is coaxially fixedly connected to a driving gear 304. The other end of the first screw rod 305 is transmission-connected to a second drive motor 306. The second drive motor 306 is fixedly connected to the side wall of the console 3. The second drive motor 306 can directly drive the rotation of the first screw rod 305, so that the positioning frame 1 slides along the first slide rail 301.

[0051] The console 3 is also fixed with a third slide rail 302, and a counterweight block 308 is slidably connected to the third slide rail 302. The counterweight block is threadedly connected to a second screw rod 307, and the second screw rod 307 passes through the counterweight block 308. The second screw rod 307 is rotatably connected to the console 3, and one end of the second screw rod 307 is coaxially fixedly connected to a driven gear 303, and the driven gear 303 is engaged with the driving gear 304. When the positioning frame 1 slides along the first slide rail 301, the driving gear 304 drives the driven gear 303 to rotate, and then the second screw rod 307 rotates, so that the counterweight block 308 slides along the third slide rail 302, and the sliding directions of the counterweight block 308 and the positioning frame 1 are opposite. The counterweight block plays a role in stabilizing the center of gravity of the entire device to prevent the center of gravity from excessively deviating from the rotation center axis.

[0052] like Figure 3 As shown, the console 3 has a circular groove at one end away from the positioning frame, within which a fixing post 4 is located. Multiple protrusions 3011 are integrally formed on the inner wall of the circular groove, evenly distributed around the center of the groove. A mounting block 401 is located between each two adjacent protrusions 3011. The mounting block 401 is fixedly connected to the bottom of the circular groove via screws, and the sidewalls of the mounting block 401 are fixedly connected to the sidewalls of the protrusions 3011 via compression springs 3012. Each of the multiple mounting blocks 401 is integrally formed with the sidewalls of one end of the fixing post 4. As the entire device rotates with the lathe fixture, the compression springs 3012 serve to absorb the shear force on the screws caused by inertia, providing a buffering effect.

[0053] In summary, a method for drilling holes in aviation accessories includes the following steps:

[0054] S100: Clamp and fix the fixed column 4 with a lathe fixture;

[0055] S200: Pre-install aviation accessories: Check and close the second electric stop valve 605, open the first electric stop valve 604, and adjust the electromagnetic reversing valve 6032 to Figure 8 At the position shown, the hydraulic oil pump 6031 is activated to fill the cylinder of the second hydraulic telescopic rod 602 with oil. Simultaneously, the cylinder of the first telescopic rod is unloading oil. Once the silicone plate 601 is in contact with the aviation component and the component does not fall, the first electric shut-off valve 604 and the hydraulic oil pump 6031 are closed in sequence.

[0056] S300: driving the second driving motor 306 to drive and adjust the position of the positioning frame 1 so that the turning tool is aligned with the position where the hole needs to be cut in the aviation component;

[0057] S400: Locking aviation accessories;

[0058] S500: Drill holes in aviation parts.

[0059] Before step S400 , the micro motor 209 is driven according to the hardness of the aviation component to adjust the appropriate contact surface between the bushing 206 and the aviation component.

[0060] The specific operation of step S400 is as follows: drive the first drive motor 102, and when the bushing 206 just contacts the aviation part, turn off the first drive motor 102; at this time, the extrusion force of the aviation part by the first slider 201 and the second slider 202 is zero. Adjust the electromagnetic reversing valve 6032 to Figure 9 As shown in the position, the hydraulic oil pump 6031 is driven to fill the oil cylinder of the first hydraulic telescopic rod 207 with oil. As soon as the first pressure detector detects the oil pressure, the electromagnetic reversing valve 6032 is adjusted to Figure 10 In the position shown, the hydraulic oil pump 6031 is turned off, and the pressure of the hydraulic oil in the first hydraulic telescopic rod 207 is zero; the first drive motor 102 is driven again, and the pressure on the aviation accessory is equal to the pressure on the first hydraulic telescopic rod 207. When the oil pressure detected by the first pressure detector and the second pressure detector is the same, the second electric stop valve 605 is opened; the two oil cylinders are connected and closed. Thereafter, as the first and second sliders squeeze the aviation accessories, the pressure on the other pair of force-bearing surfaces of the second clamping assembly 6 for pre-installation on the aviation accessories increases synchronously, so that the aviation accessories are balanced in multiple directions. When the first and second pressure detectors detect that the oil pressure reaches the preset safety value, the first drive motor 102 is turned off.

[0061] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
