Description

Technical Field

[0001] This invention relates to the field of deep hole processing technology, specifically to an internal cooling drilling and polishing combined processing device and process for deep hole processing of nickel-based alloys. Background Technology

[0002] Nickel-based alloys are a class of advanced metallic materials formed by adding various other alloying elements (such as chromium, molybdenum, cobalt, tungsten, aluminum, titanium, etc.) to nickel as the base material. They are designed to maintain excellent mechanical properties and chemical stability under extreme conditions such as high temperature, high pressure, and high corrosion. They are characterized by face-centered cubic crystal structure and strong alloying ability, and are widely used in the customization of parts. However, the customization of nickel-based alloys requires drilling and polishing.

[0003] CN111745409B discloses a multi-functional processing device for aluminum profile processing. In operation, a second motor drives a drill rod to drill holes in the side of a positioning block, creating positioning holes. Simultaneously, a first motor drives a first ball screw assembly, which in turn moves a first connecting plate and a second motor along a first slide rail, allowing adjustment of the drilling depth for easier operation and improved efficiency. Simultaneously, a third motor drives a polishing wheel to polish the upper end of the positioning block. A first cylinder drives a C-shaped fixing plate, which in turn moves the third motor along a second slide rail, adjusting the height of the polishing wheel to regulate the polishing degree of the positioning block, further enhancing efficiency. The invention also includes a transfer device that uses a vacuum nozzle to transfer the positioning plate onto a transport track, achieving both processing and transportation.

[0004] Although the aforementioned applications and prior art can integrate drilling, polishing, and transfer into a single operation, when performing deep drilling on nickel-based alloys, the exit point of the hole is uneven. The aforementioned applications cannot address this exit point during polishing, and even when polishing the exit point, fine polishing is not possible, requiring the replacement of different sandpapers. This process is time-consuming, and when changing sandpapers, debris gets trapped inside due to polishing. If not addressed promptly, this will affect subsequent normal use. Therefore, this invention proposes an internally cooled drilling and polishing combined processing device and process for deep hole machining of nickel-based alloys. Summary of the Invention

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides an internal cooling drilling and polishing combined machining device and process for deep hole machining of nickel-based alloys, which has the following beneficial effects: 1. This internally cooled drilling and polishing combined processing device and process for deep hole machining of nickel-based alloys utilizes the coordinated use of polishing and edge components. When the moving platform drives the drilling mechanism and lifting plate to rise, the lifting plate rises through the receiving cylinder, causing the extrusion plate to extrude the extrusion rod through the inner wall of the processing box. The extrusion rod then conveys the contents of the receiving cylinder to the connecting pipe through the extrusion disc, and then into the interior of the fixed cylinder. As the liquid inside the fixed cylinder continuously increases, the liquid drives the pushing rod to move through the moving disc, which in turn drives the receiving roller to move through the U-shaped frame. When the receiving roller moves, it pulls the sandpaper to wrap around the edge of the deep hole. Then, the polishing motor drives the polishing rod to rotate, causing the polishing rod to drive the sandpaper to polish the inner wall and edges of the deep hole, thereby achieving the effect of edge treatment.

[0017] 2. This internally cooled drilling and polishing combined processing device and process for deep hole machining of nickel-based alloys utilizes the combined use of polishing and fine polishing components. The fine polishing motor, driven by the fine polishing rod, rotates the transmission disc, which in turn drives the transmission bar via a fixed rod to reciprocate. This, in turn, causes the transmission bar to move a slider via a push rod. The slider, in turn, moves a conveyor disc inside the gas-generating cylinder via a push rod. Gas from inside the gas-generating cylinder continuously enters the gas storage box through a conveying pipe. When the gas pressure inside the gas storage box reaches the threshold of the pressure relief valve, the gas enters the receiving tray through the inlet pipe. The gas then drives a receiving rod to rotate via an arc-shaped blade, causing the receiving rod to wind up the sandpaper via a receiving roller. As the sandpaper winds up, sandpaper of different grits faces the deep hole, resulting in fine polishing and achieving a fine polishing effect.

[0018] 3. This internally cooled drilling and polishing combined processing device and process for deep hole machining of nickel-based alloys utilizes the combined use of a fine polishing component and a contamination-avoiding component. As the internal air pressure of the receiving tray continuously increases, the gas inside the receiving tray enters the interior of the fixed tray through the air outlet pipe. This air drives the first rotating rod to rotate via rotating blades, causing the first rotating rod to intermittently compress the striking plate via a cam. When the striking plate compresses the processing tray via the processing rod, the processing tray compresses and contracts the third spring. When the cam is no longer in contact with the striking plate, the third spring returns to its initial state, causing the processing tray to drive the processing plate via the processing rod to strike the rolled sandpaper. This striking action dislodges the debris inside the sandpaper, causing it to bounce up. Simultaneously, the first rotating rod drives the second rotating rod to rotate via a transmission mechanism, causing the second rotating rod to drive the electromagnetic roller to absorb the bounced debris, thus preventing debris from being trapped inside the sandpaper and affecting subsequent normal use, thereby achieving the effect of preventing debris from getting trapped inside.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The devices or elements referred to in the embodiments of this application or implied herein must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0024] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 5 A combined drilling and polishing apparatus for deep hole machining of nickel-based alloys with internal cooling includes: a machining box 1 and a moving platform 12 disposed inside the machining box 1. A drilling mechanism 121 is installed inside the moving platform 12. A lifting plate 122 is installed inside the moving platform 12. A control panel 11 is installed on the surface of the processing box 1. Polishing assembly 2, located on top of lifting plate 122, is used to polish the inner wall of deep holes. Polishing assembly 2 includes a polishing motor 21 fixedly connected to the top of lifting plate 122. A polishing rod 211 is fixedly connected to the output end of polishing motor 21. A feeding rod 22 is rotatably connected to the top of polishing rod 211. A sandpaper roller 221 is fixedly connected to the surface of feeding rod 22. A support plate 212 is fixedly connected to the surface of polishing rod 211. A U-shaped frame 23 is slidably connected to the top of support plate 212. A receiving rod 231 is rotatably connected inside U-shaped frame 23. A receiving roller 232 is fixedly connected to the surface of receiving rod 231. Sandpaper roller 221 is provided with sandpaper of different grits on its surface. The end of the sandpaper away from sandpaper roller 221 is provided on the surface of receiving roller 232. The corner component 3 is set on the top of the support plate 212 and is used to polish the corners of the deep hole machining outlet to avoid defects at the outlet of the deep hole. The fine polishing component 4 is set on the surface of the support plate 212 and is used to replace the polishing sandpaper during the polishing process of the inner wall and outlet of the deep hole, thereby avoiding rough polishing of the inner wall and outlet of the deep hole. The anti-fouling component 5 is set on the surface of the support plate 212 to prevent polishing debris from remaining inside the sandpaper during the replacement of polishing sandpaper and affecting subsequent use. It should be noted that a torsion spring is provided on the surface of the feeding rod 22. In the initial state, the torsion spring on the surface of the feeding rod 22 is in a stretched state. When drilling and polishing of nickel-based alloys are required, the nickel-based alloy to be drilled is placed inside the processing box 1 and fixed. Then, the drilling mechanism 121 and the lifting plate 122 are lowered by the moving platform 12, so that the drilling mechanism 121 drills the nickel-based alloy. After drilling is completed, the drilling mechanism 121 and the lifting plate 122 are raised by the moving platform 12, so that the lifting plate 122 drives the polishing rod 211 and the support plate 212 to rise through the polishing motor 21. Then, the polishing rod 211 and the support plate 212 drive the sandpaper roller 221 and the take-up roller 232 to rise respectively, so that the polishing rod 211 enters the interior of the drilled hole. Then, the polishing motor 21 is started, and the polishing motor 21 drives the polishing rod 211 and the support plate 212 to rotate, so that the sandpaper between the sandpaper roller 221 and the take-up roller 232 polishes the interior of the drilled nickel-based alloy through continuous rotation. For a specific embodiment two, please refer to Figures 1 to 8 Based on the internal cooling drilling and polishing combined machining apparatus for deep hole machining of nickel-based alloys provided in Specific Embodiment 1, this embodiment provides a further technical solution: The corner assembly 3 includes a storage cylinder 31 and a fixed cylinder 32 fixedly connected to the top of the support plate 212. The storage cylinder 31 is slidably connected to a squeezing plate 312. A first spring 311 is fixedly connected between the inside of the storage cylinder 31 and the squeezing plate 312. A squeezing rod 313 is fixedly connected to the top of the squeezing plate 312. A squeezing plate 314 is fixedly connected to the top of the squeezing rod 313. The storage cylinder 31 and the fixed cylinder 32 are connected through a connecting pipe 315. The storage cylinder 31 is filled with a pushing liquid. The fixed cylinder 32 is slidably connected to a moving plate 321. A second spring 322 is fixedly connected between the top of the moving plate 321 and the inside of the fixed cylinder 32. A pushing rod 323 is fixedly connected to the top of the moving plate 321 and inside the second spring 322. The end of the pushing rod 323 away from the moving plate 321 is fixedly connected to one side of the U-shaped frame 23. When polishing is required at the exit of the drilled hole in the nickel-based alloy, as the moving platform 12 drives the drilling mechanism 121 and the lifting plate 122 to rise, the lifting plate 122 drives the support plate 212 to rise via the polishing motor 21. This causes the support plate 212 to lift the top of its receiving cylinder 31, thereby causing the extrusion plate 314 to extrude the extrusion rod 313 through the inner wall of the processing box 1. The extrusion rod 313 then conveys the liquid inside the receiving cylinder 31 to the connecting pipe 315 via the extrusion plate 312, allowing the liquid to enter the interior of the fixed cylinder 32. As the liquid inside the fixed cylinder 32 continuously increases, the liquid drives the push rod 323 to move via the moving disk 321. The push rod 323 then drives the take-up roller 232 to move via the U-shaped frame 23. Therefore, when the take-up roller 232 moves, it pulls the sandpaper to wrap around the drill outlet of the deep hole. Thus, when the polishing motor 21 drives the polishing rod 211 and the support disk 212 to rotate, the sandpaper between the sandpaper roller 221 and the take-up roller 232 continuously polishes the inner wall and drill outlet of the nickel-based alloy drill hole. For a specific embodiment three, please refer to Figures 1 to 12 Based on the internal cooling drilling and polishing combined machining apparatus for deep hole machining of nickel-based alloys provided in Specific Embodiment 2, this embodiment provides a further technical solution: The polishing assembly 4 includes a polishing motor 41 fixedly connected to the bottom of the support plate 212 and a sliding seat 42 fixedly connected to the top of the support plate 212. A polishing rod 411 is fixedly connected to the output end of the polishing motor 41. A transmission plate 412 is fixedly connected to the surface of the polishing rod 411 and located at the top of the support plate 212. A fixing rod 413 is fixedly connected to the top of the transmission plate 412. A slider 421 is slidably connected inside the sliding seat 42. A push rod 422 is fixedly connected to the top of the slider 421. The fixing rod 413 and the push rod 422 are transmitted through a transmission bar 414. One side of the slider 421 is fixedly connected to... The push rod 423 is connected to a conveyor plate 424, and the fine polishing component 4 also includes an air-generating cylinder 43 fixedly connected to the top of the support plate 212, an air storage box 44 fixedly connected to the top of the support plate 212, and a receiving plate 45 fixedly connected to the top of the support plate 212. The conveyor plate 424 is slidably connected inside the air-generating cylinder 43. The air-generating cylinder 43 and the air storage box 44 are connected through a conveying pipe 431. The air storage box 44 and the receiving plate 45 are connected through an air inlet pipe 441. Several arc-shaped blades 451 are fixedly connected to the surface of the receiving rod 231 and inside the receiving plate 45. It should be noted that a first check valve is provided on the surface of the conveyor plate 424, a second check valve is provided on the surface of the conveyor pipe 431, and a pressure relief valve is provided on the surface of the air inlet pipe 441. When fine polishing is required on the drilled area, the fine polishing motor 41 is started. The fine polishing motor 41 drives the transmission disc 412 to rotate via the fine polishing rod 411. The transmission disc 412 drives the transmission bar 414 to reciprocate via the fixed rod 413. In turn, the transmission bar 414 drives the slider 421 to move via the push rod 422. The slider 421 drives the conveyor disc 424 to move inside the gas generator 43 via the push rod 423. This allows the gas inside the gas generator 43 to continuously enter the gas storage box 44 through the conveying pipe 431. When the air pressure inside the air storage box 44 reaches the threshold of the pressure relief valve, the gas inside the air storage box 44 enters the receiving tray 45 through the air inlet pipe 441. The gas drives the receiving rod 231 to rotate through the arc blade 451, which in turn causes the receiving rod 231 to roll up the sandpaper through the receiving roller 232. As the sandpaper is rolled up, the sandpaper surfaces with different grits face the deep hole. Therefore, when the polishing rod 211 and the support plate 212 rotate, they can perform fine polishing on the inner wall of the deep hole and the drilling outlet, thereby achieving the best polishing effect. For a specific implementation example, please refer to Implementation Example 4. Figures 1 to 15 Based on the internal cooling drilling and polishing combined machining apparatus for deep hole machining of nickel-based alloys provided in Specific Embodiment 3, this embodiment provides a further technical solution: The contamination-avoiding component 5 includes a first rotating rod 51 rotatably connected to one side of the U-shaped frame 23 and a processing cylinder 52 fixedly connected to one side of the U-shaped frame 23. A fixed plate 511 is fixedly connected to the top of the support plate 212. Several rotating blades 512 are fixedly connected to one end surface of the first rotating rod 51 and inside the fixed plate 511. The fixed plate 511 and the storage plate 45 are connected through an air outlet pipe 514. A cam 513 is fixedly connected to the surface of the first rotating rod 51. A processing plate 522 is slidably connected inside the processing cylinder 52. A third spring 521 is fixedly connected between the bottom and the inside of the processing cylinder 52. A processing rod 523 is fixedly connected to the top of the processing disc 522. A striking plate 524 is fixedly connected to the surface of the processing rod 523. A processing plate 525 is fixedly connected to the top of the processing rod 523. The anti-fouling assembly 5 also includes a second rotating rod 53 rotatably connected to the top of the U-shaped frame 23. An electromagnetic roller 531 is fixedly connected to the surface of the second rotating rod 53 and located at the top of the receiving roller 232. The second rotating rod 53 and the first rotating rod 51 are driven by a transmission mechanism 532. It should be noted that the transmission mechanism 532 includes a driving sprocket fixedly connected to the surface of the first rotating rod 51 and a driven sprocket fixedly connected to the surface of the second rotating rod 53. The driving sprocket and the driven sprocket are driven by a chain. To prevent polishing debris from remaining in the gaps of the sandpaper, as the internal air pressure of the collection tray 45 increases, the gas inside the collection tray 45 enters the interior of the fixed tray 511 through the air outlet pipe 514. This air then drives the first rotating rod 51 to rotate via the rotating blade 512. The first rotating rod 51 then intermittently compresses the striking plate 524 via the cam 513. When the striking plate 524 compresses the processing tray 522 via the processing rod 523, the processing tray 522 compresses and contracts the third spring 521. When the cam 513 is not in contact with the striking plate 524, the third spring 521 returns to its initial state, causing the processing disc 522 to drive the processing plate 525 to strike the rolled sandpaper through the processing rod 523. The striking causes the debris inside the sandpaper to be knocked out and bounced up. At the same time, the first rotating rod 51 drives the second rotating rod 53 to rotate through the transmission mechanism 532, causing the second rotating rod 53 to drive the electromagnetic roller 531 to attract the bounced debris, thereby preventing the debris from being hidden inside the sandpaper and affecting its normal use. In a specific embodiment five, the present invention also provides an internal cooling drilling and polishing combined machining process for deep hole machining of nickel-based alloys, which specifically includes the following steps: Step 1: Place the nickel-based alloy to be processed inside the processing box 1 and fix it in place. Then, use the moving platform 12 to drive the drilling mechanism 121 to drill holes in it. Step 2: After drilling is completed, the moving platform 12 synchronously drives the drilling mechanism 121 and the polishing component 2 to rise, and simultaneously drives the corner component 3 during the rising process. Step 3: The corner component 3 covers the outlet of the deep hole, and the inner wall and the outlet are polished simultaneously by the polishing component 2. Step 4: Activate the fine polishing component 4 to replace the sandpaper used for polishing, making the polishing more refined. Step 5: When the fine polishing component 4 is in operation, the dirt-avoiding component 5 is driven synchronously, so that the dirt-avoiding component 5 can handle the debris inside the sandpaper and prevent the debris from affecting subsequent use.

[0025] Working principle: In use, the nickel-based alloy to be drilled is placed inside the processing box 1 and fixed. Then, the drilling mechanism 121 and the lifting plate 122 are lowered by the moving platform 12, so that the drilling mechanism 121 drills the nickel-based alloy. After drilling, the drilling mechanism 121 and the lifting plate 122 are raised by the moving platform 12. The lifting plate 122 drives the polishing rod 211 and the support plate 212 to rise through the polishing motor 21. In turn, the polishing rod 211 and the support plate 212 drive the sandpaper roller 221 and the take-up roller 232 to rise respectively, so that the polishing rod 211 enters the interior of the drill hole. Then, the polishing motor 21 is started, and the polishing motor 21 drives the polishing rod 211 and the support plate 212 to move. The rotation causes the sandpaper between the sandpaper roller 221 and the take-up roller 232 to continuously polish the inside of the nickel-based alloy drill hole. When polishing is required at the exit of the nickel-based alloy drill hole, the moving platform 12 drives the drilling mechanism 121 and the lifting plate 122 to rise. The lifting plate 122 drives the support plate 212 to rise through the polishing motor 21, causing the support plate 212 to drive the top of the receiving cylinder 31 to rise. This causes the extrusion plate 314 to extrude the extrusion rod 313 through the inner wall of the processing box 1. The extrusion rod 313 conveys the liquid inside the receiving cylinder 31 to the connecting pipe 315 through the extrusion plate 312, allowing the liquid to enter the interior of the fixed cylinder 32. As the liquid inside the fixed cylinder 32 continuously increases, the liquid is driven by the moving plate 321... The push rod 323 moves, causing the take-up roller 232 to move via the U-shaped frame 23. As the take-up roller 232 moves, it pulls the sandpaper to cover the drilled hole exit of the deep hole. Therefore, when the polishing motor 21 drives the polishing rod 211 and the support plate 212 to rotate, the sandpaper between the sandpaper roller 221 and the take-up roller 232 continuously polishes the inner wall and exit of the nickel-based alloy drill hole. When fine polishing of the drilled area is required, the fine polishing motor 41 is started. The fine polishing motor 41 drives the transmission plate 412 to rotate via the fine polishing rod 411, causing the transmission plate 412 to drive the transmission bar 414 to reciprocate via the fixed rod 413. This, in turn, causes the transmission bar 414 to move reciprocally via the push rod 422. The slider 421 is moved, causing the push rod 423 to move the conveyor plate 424 inside the gas generator 43. Gas from inside the gas generator 43 continuously enters the gas storage box 44 through the conveyor pipe 431. When the gas pressure inside the gas storage box 44 reaches the threshold of the pressure relief valve, the gas enters the receiving plate 45 through the inlet pipe 441. The gas then drives the receiving rod 231 to rotate through the arc-shaped blades 451. This causes the receiving rod 231 to wind up the sandpaper via the receiving roller 232. As the sandpaper winds up, different grit sandpaper faces the deep hole. Therefore, when the polishing rod 211 and the support plate 212 rotate, they can perform fine polishing on the inner wall of the deep hole and the drill outlet.To achieve the best polishing effect, it is necessary to avoid leaving polishing debris in the gaps of the sandpaper. As the air pressure inside the collection tray 45 continuously increases, the gas inside the collection tray 45 enters the interior of the fixed tray 511 through the air outlet pipe 514. This air drives the first rotating rod 51 to rotate through the rotating blade 512. The first rotating rod 51 then intermittently compresses the striking plate 524 through the cam 513. When the striking plate 524 compresses the processing tray 522 through the processing rod 523, the processing tray 522 activates the third spring 521. When the cam 513 is no longer in contact with the striking plate 524, the third spring 521 returns to its initial state, causing the processing disc 522 to drive the processing plate 525 via the processing rod 523 to strike the wound sandpaper. This striking action dislodges debris from inside the sandpaper, causing it to bounce. Simultaneously, the first rotating rod 51 drives the second rotating rod 53 to rotate via the transmission mechanism 532. The second rotating rod 53 then drives the electromagnetic roller 531 to collect the bounced debris, thus preventing debris from remaining inside the sandpaper and affecting its subsequent use.
