Description

Technical Field

[0001] This invention relates to the field of drill bit technology, specifically to a drill bit and drilling unit for drilling wind turbine gear rings. Background Technology

[0002] The yaw gear ring is an important component of the yaw system in wind power equipment. Due to the fact that the design life of the yaw gear ring is generally 20 years, and the special installation location, maintenance is difficult and replacement costs are high during use. Therefore, there are very high requirements for the manufacturing precision and quality of the gear ring.

[0003] In the existing technology, milling machines are required to drill holes in the wind turbine gear rings. Milling machines are machine tools that use milling cutters to process various surfaces of workpieces. The rotation of the milling cutter is usually the main motion, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, and various curved surfaces, gears, etc. Usually, a spade drill or a crown drill is used as the milling cutter to drill holes in the wind turbine gear rings.

[0004] However, existing shovel drills require different models of drill bits to complete drilling of different sizes of wind turbine gear rings. The existing shovel drills usually use screws to fix the drill bit threads to the bottom of the shovel drill, which requires workers to tighten it from both sides of the drill bit with a screwdriver, making it difficult to quickly replace and install the shovel drill bit.

[0005] Therefore, we need a drill bit and drilling unit for wind turbine gear ring drilling to solve the problem of inconvenient and timely replacement and installation of drill bits in existing machining shovel drills, so that the machining drill bit can be replaced quickly and conveniently.

The quick-installation unit includes a track frame 5, a vertical track 6, a mounting frame 7, and a shovel drill 8. A transverse track 4 is provided on one side of the outer wall of the gantry frame 3. One side of the outer wall of the track frame 5 is electrically slidably connected to the inner wall of the transverse track 4. Sliding grooves are provided on both sides of the outer wall of the vertical track 6. One side of the outer wall of the track frame 5 is electrically slidably connected to the inner wall of the vertical track 4. One side of the sliding groove of the 6 is electrically slidably connected. One side of the outer wall of the mounting frame 7 is electrically slidably connected to the sliding groove on the side of the vertical track 6 away from the track frame 5. A running motor is fixedly installed inside the mounting frame 7. The shaft of the running motor is fixedly connected to the top outer wall of the shovel drill 8. The quick installation unit includes a drill bit 10, a locking block 12, a connecting block 13, and a rack 15. The bottom outer wall of the shovel drill 8 has an installation groove 9. The outer wall of the drill bit 10 is movably connected to the inner wall of the installation groove 9. Both sides of the outer wall of the drill bit 10 have locking grooves 11. The connecting block 13 The outer wall of the jack and the inner wall of the slot 11 are movably connected.

[0037] In this invention, the horizontal track 4 facilitates the lateral displacement of the track frame 5, and the vertical track 6 facilitates the lateral displacement of the track frame 5, thereby enabling the adjustment of different processing positions and processing heights. By displacing the locking block 12, the locking blocks 12 on both sides of the drill bit 10 can be completely inserted into the locking slot 11. At this time, the drill bit 10 is locked into the mounting slot 9 at the bottom of the shovel drill 8. When the drill bit 10 and the shovel drill 8 are completely in contact, the slots of the locking slot 11 and the locking slot 2 16 will be completely aligned. At this time, due to the principle of gravity, the locking block 12 will naturally slide from the locking slot 11 to between the locking slot 11 and the locking slot 2 16, causing the drill bit 10 to be locked and completely fixed on the inner wall of the mounting slot 9. The installation can be completed simply by aligning the drill bit 10 with the mounting slot 9 and inserting it directly. The wind turbine gear ring 17 is then processed. This device solves the problem of inconvenient and timely replacement and installation of drill bits in existing shovel drills, allowing for quick and convenient replacement of processing drill bits. Example

[0038] See attached document Figures 1 to 13Based on Embodiment 2, the dispensing unit includes a placement frame 18, a motor 19, a turntable 20, multiple placement plates 21, a support block 22, a threaded rod 23, and an anti-detachment block 24.

The top outer wall of the placement frame 18 has a shaft hole that communicates with the inner wall. The shaft of the motor 19 passes through the shaft hole and is fixedly connected to the bottom outer wall of the turntable 20. Multiple placement plates 21 are evenly distributed on the top outer wall of the turntable 20, and the bottom outer wall of the threaded rod 23 is fixedly connected to the placement plate. The top outer wall of the placement plate 21 is rotatably connected, the bottom outer wall of the anti-detachment block 24 is fixedly connected to the top outer wall of the threaded rod 23, the support block 22 is located on the top outer wall of the placement plate 21, and threaded holes are opened on both sides of the outer wall of the support block 22. The inner wall of the threaded hole is threadedly connected to the outer wall of the threaded rod 23. The top outer wall of the support block 22 is fixedly opened with a groove 25 corresponding to the drill bit 10. The quick disassembly unit includes a connecting frame 26, a slider 28, an anti-detachment strip 29, an extension frame 30, an extension plate 31, two gears 32, two wheel discs 33, a second motor 34, a belt 43, and a limit baffle 36. The connecting frame 26 is fixedly connected to one side outer wall of the support block 22. The top outer wall of the connecting frame 26 is opened with a groove 27, and the bottom of the slider 28 is... The outer wall and the inner wall of the slide 27 are movably connected. The anti-detachment strip 29 is fixedly connected to the two outer walls of the slider 28. The outer wall of the anti-detachment strip 29 is slidably connected to the inside of the slide 27. The extension frame 30 is located inside the slider 28. The two outer walls of the extension frame 30 are fixedly connected to the inner wall of the slider 28 through the extension plate 31. The two gears 32 are rotatably connected to the outer walls of both ends of the extension frame 30. The second motor 34 is fixedly connected to the outer wall of one end of the extension frame 30. The shaft of the second motor 34 passes through the extension frame 30 and is fixedly connected to the outer wall of the gear 32. The outer walls of the two wheel discs 33 are fixedly connected to the outer walls of the two gears 32. The outer wall of the belt 43 is rotatably connected to the outer walls of the two wheel discs 33. The bottom outer wall of the limiting baffle 36 is... The upper outer wall of the placement plate 21 is fixedly connected to the limit baffle 36. A limit groove 37 is opened on one side of the outer wall of the limit baffle 36. A locking hole is opened on the outer wall of the slider 28. One end of the outer wall of the motor 24 passes through the locking hole and is movably connected to the inner wall of the limit groove 37. Both sides of the outer wall of the drill bit 10 are provided with unloading grooves 35, which are connected to the locking groove 11. The locking block 12 is provided with a toothed groove 14. A rack 15 is fixed or connected to the inner wall of the toothed groove 14. The outer wall of one of the gears 32 is movably meshed with the outer wall of the rack 15. The turntable 20 is provided with multiple quick disassembly units. Each quick disassembly unit is divided into two parallel and symmetrical groups, located on the outer walls of both sides of the support block 22. The horizontal inclination angle of the limit groove 37 is greater than 45°.

[0039] The wind turbine gear ring 17 is pushed to the bottom of the shovel drill 8 for processing by the electrically controlled moving machine tool 2. After processing, the machine tool 2 moves the wind turbine gear ring 17 out, making it convenient for the staff to remove the processed wind turbine gear ring 17 to replace the next processing part. At this time, the turntable 20 on the placement frame 18 will be directly below the shovel drill 8. When it is necessary to change to a different size drill bit 10, simply move the shovel drill 8, which is aligned with the support block 22, down so that the drill bit 10 is completely inserted into the support groove 25. At this time, the outlet of the slider 28 will be directly opposite the unloading groove 35 on the drill bit 10. The drill bit 10 continues to press down, and the pressure will drive the support block 22 down. The support block 22 will drive all the devices on the connecting frame 26 down together. Due to the setting of the downward tilting limit groove 37, the slider 28 will move down along with the limit groove 37 and the slide groove 25. Under the clamping force of 7, it moves forward until it reaches the unloading groove 35. When the support block 22 is fully pressed down, the gear 32 will abut against the outer wall of the rack 15. At this time, the start motor 2 34 drives the gear 32 to rotate through the belt 43. The rotation of the gear 32 causes the chuck block 12 to slide into the slot 1 11 until the chuck block 12 is completely disengaged from the slot 2 16. At this time, the drill bit 10 has lost its connection with the shovel drill 8. The shovel drill 8 moves directly upward. The start motor 1 19 drives the turntable 20 to rotate, moving the drill bit 10 that needs to be replaced to directly below the shovel drill 8 for replacement. This device achieves the effect of quick disassembly and quick replacement by simply moving the drill bit 10 downward. It further solves the problem of inconvenient and timely replacement of drill bits in existing shovel drills, and allows for quick and convenient replacement of processing drill bits. Example

[0040] See attached document Figures 1 to 13 Based on Embodiment 2, this embodiment adds a chip-prevention unit:

[0041] The chip-proof unit includes a protective plate 39. The inner walls on both sides of the entrance of the unloading trough 35 are provided with protective grooves 38. The protective plate 39 is divided into two. The outer walls of the two protective plates 39 are movably connected to the inner walls of the two protective plates 39 respectively. The protective groove 38 is a groove that extends obliquely backward at a 45° angle and obliquely downward at a 30° angle. The shape of the outer wall of the protective plate 39 corresponds to the shape of the inner wall of the protective groove 38.

[0042] Since the drill bit 10 is equipped with an unloading groove 35, iron filings may splash into the unloading groove 35 during processing. In this invention, two downward-inclined protective plates 39 are provided. When the drill bit 10 rotates at high speed with the shovel drill 8, the centrifugal force of rotation will drive the two protective plates 39 outward along with the protective groove 38. Since they move at an inclined angle, when the two protective plates 39 reach the unloading groove 35, they will collide with each other and block each other's path, thus completely blocking the entrance of the unloading groove 35. The physical obstruction of the protective plates 39, combined with the high-speed centrifugal force, prevents iron filings from entering the unloading groove 35. When processing is completed, the shovel drill 8 stops rotating, and the protective plates 39 lose the high-speed centrifugal force and will slide back into the protective groove 38 under their own gravity, thus reopening the unloading groove 35. This facilitates the quick replacement and installation of the drill bit 10, further solving the problem of inconvenient and timely replacement and installation of the drill bit in existing processing shovel drills, and allowing for quick and convenient replacement of the processing drill bit. Example

[0043] See attached document Figures 1 to 13 Based on Embodiment 3, this embodiment adds an anti-friction unit:

[0044] The anti-friction unit includes pulley 41 and pulley 45. A cavity 40 is provided on the bottom outer wall of the protective plate 39. The outer wall of pulley 41 is rotatably connected to the inner wall of cavity 40. A cavity 44 is provided on one side outer wall of the protective plate 39. The outer wall of pulley 45 is rotatably connected to the inner wall of cavity 44.

[0045] By installing pulley 41 and pulley 45, the frictional force of the protective plate 39 in the groove 38 can be reduced, which can further prevent the protective plate 39 from getting stuck in the groove 38, and close the entrance of the unloading groove 35 more quickly and smoothly. This further solves the problem that the drill bit is inconvenient to replace and install in time in the existing processing drill, and the processing drill bit can be replaced quickly and conveniently. Example

[0046] Please see Figures 1 to 13 The present invention provides a method for using a drilling unit, which includes a wind turbine gear ring drilling bit as described in any one of the above embodiments one to four.

[0047] Step 1: By opening the horizontal track 4, the horizontal displacement of the track frame 5 is facilitated. By installing the track frame 5, the horizontal displacement of the vertical track 6 is facilitated, thereby completing the adjustment of different processing positions and processing heights. By displacing the locking block 12, the locking blocks 12 on both sides of the drill bit 10 can be completely inserted into the first slot 11. At this time, the drill bit 10 is locked into the mounting groove 9 at the bottom of the shovel drill 8. When the drill bit 10 and the shovel drill 8 are completely in contact, the slots of the first slot 11 and the second slot 16 will be completely aligned. At this time, due to the principle of gravity, the locking block 12 will naturally slide from the first slot 11 to between the first slot 11 and the second slot 16, causing the drill bit 10 to be locked in place on the inner wall of the mounting groove 9. The installation can be completed by simply aligning the drill bit 10 with the mounting groove 9 and inserting it directly. The wind turbine gear ring 17 is then processed. This device solves the problem of the difficulty in quickly replacing and installing the shovel drill bit.

[0048] Step Two:

[0049] The wind turbine gear ring 17 is pushed to the bottom of the shovel drill 8 by the electrically controlled moving machine tool 2 for processing. After processing, the machine tool 2 moves the wind turbine gear ring 17 out, making it convenient for the operator to remove the processed wind turbine gear ring 17 to replace the next processing part. At this time, the turntable 20 on the placement frame 18 will be directly below the shovel drill 8. When it is necessary to change to a different size drill bit 10, simply move the shovel drill 8, which is aligned with the support block 22, downward so that the drill bit 10 is completely inserted into the support groove 25. At this time, the outlet of the slider 28 will be directly aligned with the unloading groove 35 on the drill bit 10. The drill bit 10 continues to press down, and the pressure will drive the support block 22 to move down. The support block 22 will drive all the devices on the connecting frame 26 to move down together. Due to the setting of the downward tilting limit groove 37, the guide As the slider 28 moves downward, it moves forward under the clamping and coercion of the limiting groove 37 and the sliding groove 27 until it extends into the unloading groove 35. When the support block 22 is fully pressed down, the gear 32 will abut against the outer wall of the rack 15. At this time, the starter motor 34 drives the gear 32 to rotate through the belt 43. The rotation of the gear 32 causes the locking block 12 to slide into the locking groove 11 until the locking block 12 is completely disengaged from the locking groove 16. At this time, the drill bit 10 has lost its connection with the shovel drill 8. The shovel drill 8 moves directly upward. The starter motor 19 drives the turntable 20 to rotate, moving the drill bit 10 that needs to be replaced directly below the shovel drill 8 for replacement. This device achieves the effect of quick disassembly and quick replacement by simply moving the drill bit 10 downward.

[0050] Step 3: In this invention, two downward-inclined protective plates 39 are provided. When the drill bit 10 rotates at high speed with the shovel drill 8, the centrifugal force of rotation will cause the two protective plates 39 to detach outward with the groove 38. Since they move at an inclined angle, when the two protective plates 39 reach the unloading groove 35, they will collide with each other and block each other's path, thus completely blocking the entrance of the unloading groove 35. The physical obstruction of the protective plates 39, combined with the high-speed centrifugal force, prevents iron filings from entering the unloading groove 35. After processing is completed, the shovel drill 8 stops rotating, and the protective plates 39 lose the high-speed centrifugal force and will slide back into the groove 38 under their own weight, thus reopening the unloading groove 35. This facilitates the quick replacement and installation of the drill bit 10. By installing pulley 1 41 and pulley 2 45, the friction of the protective plates 39 in the groove 38 can be reduced, which can further prevent the protective plates 39 from getting stuck in the groove 38 and close the entrance of the unloading groove 35 more quickly and smoothly.
