Description

Technical Field

[0001] This invention belongs to the field of turning technology, and specifically discloses a drilling device for deep machining of aluminum alloy flanges. Background Technology

[0002] In existing flange assembly drilling processes, multiple flange parts are typically overlapped and fixed, and then a punching and turning machine is used to perform a one-time through-hole drilling. While this traditional method improves processing efficiency to some extent, the overall drilling depth increases significantly when multiple flanges are stacked, easily generating continuous long chips during continuous drilling. These excessively long chips are difficult to remove smoothly and tend to wrap around the drill bit or workpiece surface, not only scratching the machined hole wall and flange end face, affecting hole diameter accuracy and surface quality, but also potentially causing blockage of the drill bit's chip removal grooves, increased cutting load, and consequently, accelerated drill bit wear, shortened lifespan, and even tool breakage. Furthermore, long chips can easily fly out with the rotating drill bit, posing a safety hazard. Cleaning intermittently wrapped chips also adds downtime, reducing processing continuity and overall production efficiency. Therefore, the problems of "difficult chip control, unstable processing quality, high tool wear, and prominent safety hazards" in existing technologies for drilling multiple stacked flanges urgently need to be addressed through process and equipment improvements.

[0003] Therefore, the present invention proposes a drilling device for deep machining of aluminum alloy flanges to solve the above-mentioned defects. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the background art, and to propose a drilling device for deep machining of aluminum alloy flanges, including a turning table, a Y-axis guide table, a Y-axis slide, an X-axis slide, and a turning and drilling device. Two sets of Y-axis guide tables are provided and are respectively fixedly installed on both sides of the outer wall of the turning table. A Y-axis reciprocating mechanism is installed at one end of each set of Y-axis guide tables. The bottom sides of the Y-axis slide are slidably connected to the top of the two sets of Y-axis guide tables via symmetrically installed Y-axis sliders. X-axis slides are fixedly installed on both sides of the upper end face of the Y-axis slide, and the X-axis slide is slidably connected to the top of the slide via symmetrically installed X-axis sliders on its bottom sides. The Y-axis slide is connected above two sets of X-axis slides. An X-axis slide rail mechanism is installed inside one end of the Y-axis slide. The X-axis slide rail mechanism is connected to the X-axis slide and is used to drive the X-axis slide to slide back and forth along the length of the X-axis slide. A support frame is vertically installed above the X-axis slide. The upper part of the support frame is connected to the turning and drilling device through a lifting component. Rotary motors are fixedly installed on both sides of the upper part of the turning table. A kit table is fixedly installed at the output end of each of the two rotary motors. Multiple flanges are fitted on the outside of the kit table. Chip clamping mechanisms are provided on the upper surface of the turning table and on both the front and rear sides centered on the kit table.

[0005] In the above technical solution, the lifting component further includes a first hydraulic cylinder fixedly installed inside the support frame, and the telescopic end of the first hydraulic cylinder is connected to the top shell of the turning and drilling device.

[0006] In the above technical solution, the chip clamping mechanism further includes a base fixedly installed on the upper surface of the turning table, an L-shaped seat fixedly installed on the upper surface of the base, a second hydraulic cylinder fixedly embedded in one side of the L-shaped seat, a rail frame fixedly installed on the telescopic end of the second hydraulic cylinder, a support plate fixedly installed in one side of the rail frame, and a lifting mechanism provided on the upper surface of the support plate.

[0007] In the above technical solution, the lifting mechanism further includes a third hydraulic cylinder fixedly installed on the upper surface of the support plate. The telescopic end of the third hydraulic cylinder is fixedly connected to a shell. A flipping motor is fixedly installed inside the shell. A shaft is fixedly installed at the output end of the flipping motor. A mounting bracket is fixedly sleeved on the outside of the shaft. A servo motor is fixedly installed at the lower part inside the mounting bracket. A gear is fixedly installed on the outside of the output end of the servo motor. A limit ring is fixedly installed on the outside of one end of the mounting bracket. Rotating locking parts are arranged at equal intervals along the circumferential direction inside the limit ring.

[0008] In the above technical solution, the rotating locking component further includes a ball bearing that is installed through the inside of the limiting ring. A toothed ring is rolled on the upper part of the ball bearing. An annular groove is opened in the lower part of the toothed ring to cooperate with the rolling of the ball bearing. The toothed ring is meshed with a gear.

[0009] In the above technical solution, a curved ring shell is fixedly embedded in the upper part of the toothed ring, and curved guide strips are installed at equal intervals along the circumferential direction on the outer surface of the curved ring shell. Angled cutting tools are symmetrically installed on the outer surface of the curved guide strips near the lower end, and an angled blowing component is provided in the lower part of the inside of the curved ring shell.

[0010] In the above technical solution, the inclined blowing component further includes a ring tube fixedly embedded in the lower part of the curved ring shell. Multiple inclined blowing pipes are installed at equal intervals along the circumferential direction inside the ring tube. One end of the inclined blowing pipe penetrates the outer surface of the curved ring shell. One end of the ring tube is connected to an air pump through a connecting pipe. The air pump is fixedly installed on the outside of the curved ring shell through a fixedly fitted shell.

[0011] In the above technical solution, a wiping block is fixedly installed on the outer surface of the curved guide strip near the upper end. A sliding groove adapted to slide one end of the mounting bracket is opened inside the upper part of the rail frame. A backing plate is fixedly installed on the upper part of the outer side of the rail frame. The outer surface of one side of the backing plate is in contact with the outer edge of the flange.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the coordinated design of the chip clamping mechanism and the drilling mechanism, precise control and efficient chip removal are achieved during drilling of multiple flanges, completely solving the problems of long chip entanglement, workpiece scratching, and tool clogging in traditional machining. The curved guide strip on the outer surface of the curved ring shell can guide the chips generated by drilling to the beveling cutter. The servo motor drives the gear ring to rotate, driving the beveling cutter to dynamically cut along the circumference of the flange, breaking long chips into short chips. Combined with the oblique airflow of the oblique blowing component inside the curved ring shell, the negative pressure generated by the air pump forms a directional airflow through the ring pipe and oblique blowing pipe, which quickly removes the broken chips from the machining area, avoiding chip residue from scratching the hole wall and flange end face. At the same time, it reduces the chip removal load of the drill bit, reduces drill bit wear and the risk of tool breakage, extends tool life, and improves the safety and continuity of the machining process.

[0014] 2. By installing abutment plates on both sides of multiple flanges, the coaxiality and stability of multi-flange stacking processing are ensured, significantly improving drilling accuracy. The lifting mechanism adjusts the height via a third hydraulic cylinder, allowing the mounting bracket to move out from above the rail frame. Then, after processing, the flipping motor drives the shaft, mounting bracket, and curved ring shell to flip, causing the wiping block of the curved guide strip to fit against the flange surface. After rotating the flange, the wiping block at the curved guide strip cleans the uppermost drilled surface.

[0015] 3. Through the synergistic effect of the above functions, this invention realizes continuous composite processing of aluminum alloy flange stacking drilling, online burr cleaning of hole openings, and real-time chip adsorption and removal. Multiple processes are completed in a single clamping, significantly reducing auxiliary time and machine tool downtime, and improving overall processing efficiency, product quality stability, and working environment safety. It achieves continuous processing and reduces manual labor intensity. The automated chip breaking and removal avoids the tedious process of manual chip cleaning, further improving overall processing efficiency. It is suitable for large-scale, batch flange drilling production scenarios. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0026] like Figures 1-7The drilling device for deep machining of aluminum alloy flanges shown includes a turning table 1, a Y-axis rail 2, a Y-axis slide 3, an X-axis slide 8, and a turning and drilling device 9. Two sets of Y-axis rails 2 are provided and fixedly installed on both sides of the outer wall of the turning table 1. A Y-axis reciprocating mechanism 5 is installed at one end of each set of Y-axis rails 2. The bottom sides of the Y-axis slide 3 are slidably connected to the two sets of Y-axis rails 2 via symmetrically installed Y-axis sliders 4. X-axis slides 39 are fixedly installed on both sides of the upper end face of the Y-axis slide 3. The X-axis slide 8 is slidably connected to the two sets of X-axis slides 39 via symmetrically installed X-axis sliders 7 on its bottom sides. The X-axis slide rail mechanism 6 is installed inside one end of the Y-axis slide 3. The X-axis slide rail mechanism 6 is connected to the X-axis slide 8 and is used to drive the X-axis slide 8 to slide back and forth along the length of the X-axis slide table 39. A support frame 10 is vertically installed above the X-axis slide 8. The upper part of the support frame 10 is connected to the turning and drilling device 9 through a lifting component. Rotary motors 21 are fixedly installed on both sides of the upper part of the turning table 1. A kit table 12 is fixedly installed at the output end of the two rotary motors 21. Multiple flanges 14 are fitted on the outside of the kit table 12. A chip clamping mechanism is provided on the upper surface of the turning table 1 and on both the front and rear sides centered on the kit table 12.

[0027] In this embodiment, the Y-axis reciprocating mechanism 5 uses components such as electric push rods and stop blocks to drive the Y-axis slide 3 to reciprocate linearly in the Y-axis direction. The X-axis slide rail mechanism 6 uses components such as motors and ball screws to drive the X-axis slide 8 to reciprocate linearly in the X-axis direction, in order to cooperate with the opening and positioning of the turning and drilling device 9. During turning, the chip clamping mechanism is positioned and clamped on both sides of the front end of the multiple stacked flanges 14 to ensure stability during drilling.

[0028] The lifting component includes a first hydraulic cylinder 11 fixedly installed inside the support frame 10, and the telescopic end of the first hydraulic cylinder 11 is connected to the top shell of the turning and drilling device 9.

[0029] In this embodiment, the extension and retraction of the first hydraulic cylinder 11 can control the feed and height adjustment of the turning drilling device 9.

[0030] The chip clamping mechanism includes a base 22 fixedly installed on the upper surface of the turning table 1, an L-shaped seat 15 fixedly installed above the base 22, a second hydraulic cylinder 13 fixedly embedded in one side of the L-shaped seat 15, a rail frame 17 fixedly installed at the telescopic end of the second hydraulic cylinder 13, a support plate fixedly installed in one side of the rail frame 17, and a lifting mechanism provided on the upper surface of the support plate.

[0031] In this embodiment, the rail frame 17 is a rectangular frame structure. A horizontal support plate is fixedly installed inside the frame near the kit platform 12 by welding. A lifting mechanism is provided on the upper surface of the support plate to adjust the height and angle of the chip processing component.

[0032] The lifting mechanism includes a third hydraulic cylinder 19 fixedly mounted on the upper surface of the support plate. The telescopic end of the third hydraulic cylinder 19 is fixedly connected to a housing 18. A flipping motor 16 is fixedly mounted inside the housing 18. A shaft 32 is fixedly mounted on the output end of the flipping motor 16. A mounting bracket 33 is fixedly sleeved on the outside of the shaft 32. A servo motor 34 is fixedly mounted on the lower part of the mounting bracket 33. A gear 31 is fixedly mounted on the outside of the output end of the servo motor 34. A limit ring 25 is fixedly mounted on the outside of one end of the mounting bracket 33. Rotating locking parts are arranged at equal intervals along the circumferential direction inside the limit ring 25.

[0033] In this embodiment, the casing 18 is a sealed rectangular casing, inside which a flip motor 16 is fixedly mounted via a motor mount. The output end of the flip motor 16 is horizontally positioned and connected to the shaft 32. A mounting bracket 33 is fixedly sleeved on the outside of the shaft 32 via a flat key. The mounting bracket 33 is an L-shaped plate structure, with the output end of the servo motor 34 inside facing upwards, and a gear 31 is fixedly mounted on its outside via a flat key.

[0034] Mounting bracket 33 is fixedly mounted on the outer side of one end near the kit platform 12 by welding a limiting ring 25. The limiting ring 25 is a ring structure, and multiple sets of rotating locking parts are arranged at equal intervals along the circumference inside it to realize the rotation drive of the chip processing component.

[0035] The rotating locking component includes a ball limit bearing 35 that is installed through the inside of the limit ring 25. A toothed ring 26 is rolled on the upper part of the ball limit bearing 35. An annular groove is opened in the lower part of the toothed ring 26 to cooperate with the rolling of the ball limit bearing 35. The toothed ring 26 is meshed with the gear 31.

[0036] In this embodiment, the outer toothed ring of the toothed ring 26 is meshed with the gear 31. The rotation of the gear 31 can drive the toothed ring 26 to rotate above the outside of the ball bearing 35. The annular groove opened inside the lower part of the toothed ring 26 can roll with the balls of the ball bearing 35 to reduce the friction when the toothed ring 26 rotates.

[0037] A curved ring shell 24 is fixedly embedded in the upper part of the toothed ring 26. Curved guide strips 28 are installed at equal intervals along the circumferential direction on the outer surface of the curved ring shell 24. An inclined cutter 23 is symmetrically installed on the outer surface of the curved guide strip 28 near the lower end. An inclined blower is provided in the lower part of the inside of the curved ring shell 24.

[0038] In this embodiment, the curved annular shell 24 has a concave arc-shaped structure, and the curved guide strip 28 has an arc-shaped protrusion structure for guiding the chip flow. Two oblique cutting blades 23 are installed on the outer surface of each curved guide strip 28 near its lower end. The cutting edges of the oblique cutting blades 23 face the chip flow direction to cut long chips. An oblique blower is provided inside the lower part of the curved annular shell 24 to remove the cut chips from the processing area.

[0039] The oblique blowing component includes an annular tube 38 fixedly embedded in the lower part of the curved annular shell 24. Multiple oblique blowing tubes 36 are installed at equal intervals along the circumferential direction inside the annular tube 38. One end of the oblique blowing tube 36 penetrates the outer surface of the curved annular shell 24. One end of the annular tube 38 is connected to an air pump 37 through a connecting pipe 30. The air pump 37 is fixedly installed on the outside of the curved annular shell 24 through a fixedly fitted shell 29.

[0040] In this embodiment, the annular tube 38 is an annular hollow tube. One end of the inclined blowpipes 36, which are equidistant along the circumference inside the tube, penetrates the outer surface of the curved annular shell 24, and the outlet faces obliquely upward. One end of the annular tube 38 is connected to a connecting pipe 30 via a tee connector. The other end of the connecting pipe 30 is connected to the air intake of the air pump 37. The air pump 37 is fixedly installed on the outer wall of the curved annular shell 24 via a fixed sleeve 29. When long chips are cut into short chips, the inclined blowpipes 36 blow the short chips out of the processing area.

[0041] A wiping block 27 is fixedly installed on the outer surface of the curved guide strip 28 near the upper end. A sliding groove is provided inside the upper part of the rail frame 17 to adapt to the sliding of one end of the mounting bracket 33. A backing plate 20 is fixedly installed on the upper part of the rail frame 17. One side of the outer surface of the backing plate 20 is in contact with the outer edge of the flange 14.

[0042] In this embodiment, after the hole machining is completed, the third hydraulic cylinder 19 adjusts the height of the mounting bracket 33 to move it away from the slide groove. Then, the flip motor 16 drives the shaft 32 and the curved ring shell 24 to flip, so that the wiping block 27 is attached to the upper surface of the flange 14. The rotary motor 21 drives the flange 14 to rotate at a low speed, and the servo motor 34 drives the curved ring shell 24 to rotate. The wiping block 27 cleans the upper surface of the flange 14. Because of the curvature of the curved guide strip 28, there will be gaps when in contact. At this time, the inclined blow pipe 36 sprays correspondingly onto the flange 14 to blow away the waste on the upper surface of the flange 14 through the gaps. After completion, the operator removes the flange 14.

[0043] Working principle: Before machining, multiple flanges 14 to be drilled are sequentially fitted onto the outer sides of the mounting platforms 12 on both sides above the turning table 1. After fitting, the second hydraulic cylinder 13 in the chip clamping mechanism is activated. The telescopic end of the second hydraulic cylinder 13 pushes the rail frame 17 to move horizontally until the outer surface of the abutment plate 20 on the upper side of the rail frame 17 is tightly fitted with the outer edge of the flange 14. The abutment plates 20, symmetrically arranged on both the front and rear sides, clamp the flanges 14 together, ensuring that the multiple stacked flanges 14 maintain coaxiality, providing a stable clamping foundation for subsequent precise drilling.

[0044] After clamping, the drilling process begins. The Y-axis reciprocating mechanism 5 is activated, causing the Y-axis slide 3 to move precisely in the Y direction along the two sets of Y-axis rails 2 via its bottom Y-axis slider 4. Simultaneously, the X-axis slide mechanism 6 within the Y-axis slide 3 activates, driving the X-axis slide 8 to move precisely in the X direction along the X-axis slide 39 via its bottom X-axis slider 7. Through the coordinated movement of this XY two-dimensional precision displacement platform, the turning and drilling device 9, mounted above the X-axis slide 8, is quickly positioned directly above the target hole.

[0045] Subsequently, the first hydraulic cylinder 11 inside the support frame 10 extends, driving the turning and drilling device 9 to feed downwards, performing a one-time through-hole drilling on the stacked flange 14 groups. During drilling, the curved guide strip 28 on the outer surface of the curved ring shell 24 and the oblique cutter 23 mounted on it are both located outside the drill bit. During the generation of long chips, the servo motor 34 starts, driving the gear ring 26 meshing with it to rotate smoothly under the support of the ball bearing 35 through the gear 31. The curved guide strip 28 on the outer surface of the curved ring shell 24 rotates with it, guiding the long chips generated by drilling to the area below the curved guide strip 28. At the end of the bevel cutter 23, the bevel cutter 23 dynamically cuts around the curved ring shell 24, breaking long chips into short chips to prevent long chips from wrapping around the drill bit or workpiece. At the same time, the air pump 37 is fixedly installed on the outside of the curved ring shell 24 through the sleeve 29 and rotates with the curved ring shell 24. The air pump 37 generates negative pressure and supplies air to the ring pipe 38 at the bottom inside the curved ring shell 24 through the connecting pipe 30. Multiple oblique blow pipes 36 installed at equal intervals along the circumference of the ring pipe 38 spray oblique airflow to quickly remove the broken short chips from the processing area, reduce the chip removal load of the drill bit, and prevent chip residue from scratching the hole wall or the end face of the flange 14.

[0046] Subsequently, the first hydraulic cylinder 11 drives the turning and drilling device 9 to rise and reset. The position can be adjusted through the two-axis mechanism to process the next hole. During this process, the abutment plate 20 can flexibly move away from the flange 14 according to the current opening position of the flange 14 before clamping the flange 14. After the hole is processed, the third hydraulic cylinder 19 is started to drive the shell 18 and the tilting motor 16 to move upward. The shaft 32 and the mounting bracket 33 connected to the tilting motor 16 also move upward together until one end of the mounting bracket 33 is disengaged from the slide groove of the rail frame 17. Then, the output end of the tilting motor 16 drives the shaft 32 and the mounting bracket 33 outside the shaft 32 to tilt, so that the curved guide strip 28 on the curved ring shell 24 near the upper end of the wiping block 27 tilts to fit with the hole surface of the flange 14.

[0047] Then, the rotary motor 21 is started. The rotary motor 21 is fixed inside the upper part of the turning table 1. Its output end drives the kit table 12 and the flange 14 to rotate synchronously. The wiping block 27 wipes the hole surface with the rotation of the flange 14 to remove the burrs and small chips remaining in the drilling and improve the surface quality of the flange 14.

[0048] The entire machining process enables continuous operation of 14-layer flange clamping, precise drilling, automated chip handling, and hole surface cleaning, effectively solving the problems of chip entanglement, low machining accuracy, and high tool wear in traditional machining.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
