Description

Technical Field

[0001] This invention relates to the field of drilling technology, and in particular to a drilling device and method for processing aluminum alloy sheets. Background Technology

[0002] Aluminum alloy sheet is an industrial building material. During the processing of existing aluminum alloy sheets, holes need to be drilled on the surface of the sheet according to different applications and needs, so that the aluminum alloy sheet can be processed into various profiles.

[0003] A search of existing technologies revealed that Chinese Patent CN216096524U discloses a drilling device for processing aluminum alloy sheets. By passing the aluminum alloy sheet to be drilled between a first fixed round rod and a second fixed round rod, a motor is started to drive the lead screw to rotate, causing the second fixed round rod, which is threaded to rotate around the lead screw, to move, thus enabling the drilling of aluminum alloy sheets of different thicknesses and sizes.

[0004] However, it is worth considering that this drilling method involves placing the sheet material horizontally and drilling the sheet material vertically. When using aluminum alloy sheets to build frame structures (industrial equipment protective covers, robot fences, automated equipment racks, display cabinets, etc.), holes need to be drilled on the sides of the sheet material to install panels, hinges, sensors, cable trays, or other functional modules. When drilling holes on the sides of the sheet material, it is also necessary to change other clamps to fix the vertically placed sheet material, or to transfer the sheet material to another drilling device. This results in a limited range of applications and certain limitations.

[0005] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0016] The present invention also provides a drilling method for processing aluminum alloy sheets, applied to the drilling device for processing aluminum alloy sheets as described above, comprising the following steps: Step 1: According to the specifications of the aluminum alloy sheet, the staff selects a clamping seat that matches the receiving chamber. The staff drives the clamping seat to move so that the prism is inserted into the corresponding slide groove. Step 2: After all the clamping seats are installed, the worker drives the aluminum alloy sheet that needs to be drilled to be placed between two adjacent clamping seats. The worker then drives the two adjacent clamping seats to move closer together, and the prism slides relative to the slide groove so that the two ends of the aluminum alloy sheet are inserted into the two adjacent receiving chambers respectively. Step 3: After all the plates are installed, the rotating column is driven to move horizontally by the clamping and flipping structure. The rotating column and the slide slide relative to the prism until the end of the prism away from the clamping seat abuts against the inner wall of the slide, and the two ends of the aluminum alloy plate abut against the inner wall of the receiving chamber, so that the two adjacent clamping seats clamp the aluminum alloy plate. Step 4: Drive the annular rotating box, clamping seat and aluminum alloy plate to rotate through the drive mechanism, so that the clamping and flipping structure on the annular rotating box drives the aluminum alloy plate that needs to be drilled to rotate to the drilling station in sequence through the rotating column and clamping seat, and drill holes in the aluminum alloy plate located at the drilling station through the drilling assembly. Step 5: When it is necessary to drill holes on the side of the aluminum alloy sheet, the clamping and flipping structure drives several rotating columns to rotate. The rotating columns drive the clamping seat and the aluminum alloy sheet to rotate so that the side of the aluminum alloy sheet faces the drilling assembly. The drive mechanism drives the annular rotating box to rotate so that the aluminum alloy sheet to be drilled rotates to the drilling station in sequence. The drilling assembly drills holes in the aluminum alloy sheet located at the drilling station.

[0017] The beneficial effects of this invention are as follows: The rotating column is driven to translate by the clamping and flipping structure. The rotating column and the slide groove slide relative to the prism until the end of the prism away from the clamping seat abuts against the inner wall of the slide groove, and both ends of the aluminum alloy plate abut against the inner wall of the receiving chamber, so that two adjacent clamping seats clamp the aluminum alloy plate. The driving mechanism drives the annular rotating box, clamping seats, and aluminum alloy plate to rotate, so that the clamping and flipping structure on the annular rotating box drives the aluminum alloy plate to be drilled to rotate sequentially to the drilling position through the rotating column and clamping seat. The drilling assembly drills holes in the aluminum alloy plate located at the drilling position. When it is necessary to drill holes on the side of the aluminum alloy plate, several rotating columns are driven to rotate by the clamping and flipping structure. The rotating column drives the clamping seat and aluminum alloy sheet to rotate, so that the side of the aluminum alloy sheet faces the drilling component. The drive mechanism then drives the annular rotating box to rotate, so that the aluminum alloy sheets to be drilled are rotated to the drilling station in sequence. The drilling component drills the aluminum alloy sheets located at the drilling station. The processing of different sides of the aluminum alloy sheet can be completed in one clamping. The positioning reference of all sheets does not change during the processing, avoiding positioning errors caused by secondary clamping and ensuring the relative accuracy of the face position of the processed surface. All sheets are processed by the same drilling component at the same station, ensuring the consistency of batch products. Multiple aluminum alloy sheets can be clamped at one time, which improves drilling efficiency compared to single-piece processing. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0022] Example 1, by Figure 1 , Figure 5 , Figure 6 and Figure 7 The present invention includes a support platform 1 and a mounting bracket 2 fixedly installed on the top of the support platform 1, and further includes: The workstation adjustment assembly includes two annular rotating boxes 3 disposed above the support platform 1 and a drive mechanism for driving the annular rotating boxes 3 to rotate. The flipping assembly includes several clamping seats 5 arranged on one side of two annular rotating boxes 3, and the clamping seats 5 are arranged in a circle. Several rotating columns 4 adapted to the clamping seats 5 are passed through the annular rotating box 3. The rotating columns 4 have a groove 7 on the side facing the clamping seat 5. The clamping seat 5 has a receiving chamber for receiving the end of the plate on one side. The other side of the clamping seat 5 is fixedly connected to a prism 6 inserted into the groove 7. The mounting frame 2 is provided with a clamping flipping structure for driving the several rotating columns 4 to translate and rotate. The drilling assembly is mounted on the mounting frame 2 and is used to drill holes in the plate located at the drilling station. The drive mechanism drives the annular rotating box 3 to rotate, so that the clamping and flipping structure on the annular rotating box 3 drives the plate to be drilled to rotate sequentially to the drilling station through the rotating column 4 and the clamping seat 5. According to the specifications of the aluminum alloy sheet, the staff selects a clamping seat 5 that matches the receiving chamber. The staff drives the clamping seat 5 to move so that the prism 6 is inserted into the corresponding slide groove 7. After all the clamping seats 5 are installed, the staff drives the aluminum alloy sheet to be drilled to be placed between two adjacent clamping seats 5. The staff then drives the two adjacent clamping seats 5 to move closer together, and the prism 6 slides relative to the slide groove 7 so that both ends of the aluminum alloy sheet are inserted into the two adjacent receiving chambers respectively. After all the sheets are installed, the rotating column 4 is driven to translate by the clamping flipping structure. The rotating column 4 and the slide groove 7 slide relative to the prism 6 until the end of the prism 6 away from the clamping seat 5 abuts against the inner wall of the slide groove 7, and both ends of the aluminum alloy sheet abut against the inner wall of the receiving chamber respectively, so that the two adjacent clamping seats 5 clamp the aluminum alloy sheet. The driving mechanism drives the annular rotating box 3, the clamping seats 5 and the aluminum alloy sheet to rotate, so that the clamping flipping structure on the annular rotating box 3 passes through the rotating column 4. The aluminum alloy sheet to be drilled is driven by the clamping base 5 to rotate sequentially to the drilling station. The drilling assembly drills holes in the aluminum alloy sheet at the drilling station. When drilling is required on the side of the aluminum alloy sheet, several rotating columns 4 are driven to rotate by the clamping and flipping structure. The rotating columns 4 drive the clamping base 5 and the aluminum alloy sheet to rotate so that the side of the aluminum alloy sheet faces the drilling assembly. The drive mechanism drives the annular rotating box 3 to rotate again, so that the aluminum alloy sheet to be drilled is rotated sequentially to the drilling station. The drilling assembly drills holes in the aluminum alloy sheet at the drilling station. The processing of different sides of the aluminum alloy sheet can be completed in one clamping. The positioning reference of all sheets does not change during the processing, avoiding positioning errors caused by secondary clamping and ensuring the relative accuracy of the face position of the processed surface. All sheets are processed by the same drilling assembly at the same station, ensuring the consistency of batch products. Multiple aluminum alloy sheets can be clamped at one time, which improves drilling efficiency compared to single-piece processing.

[0023] Example 2, based on Example 1, is... Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10The clamping and flipping structure includes a rotating disk 11 fixedly installed on the end of the rotating column 4 away from the clamping seat 5. Positioning rings 14 are respectively provided on the opposite sides of the two annular rotating boxes 3. Annular grooves 15 adapted to the rotating disk 11 are formed on the inner wall of the positioning rings 14, and the end of the rotating disk 11 away from the center of the positioning rings 14 is located within the annular grooves 15. Several third hydraulic telescopic rods 30 are fixedly connected to the mounting frame 2, and the telescopic ends of the third hydraulic telescopic rods 30 are fixedly connected to the corresponding positioning rings 14. Positioning rings 14 are equipped with mechanisms for driving the several rotating columns 4 to rotate synchronously. The rotating mechanism includes a rotating sleeve 8 fitted around the outside of the rotating column 4, and the rotating sleeve 8 is rotatably connected to the annular rotating box 3. The inner wall of the rotating sleeve 8 has several first guide grooves 9. Several first guide strips 10 are fixedly connected to the outside of the rotating column 4, and the first guide strips 10 pass through the corresponding first guide grooves 9. The annular rotating box 3 has a meshing component for driving the several rotating sleeves 8 to rotate synchronously. A movable frame 16 is provided on the side of the positioning ring 14 away from the annular rotating box 3. Several first hydraulic telescopic rods 17 are fixedly connected to the positioning ring 14. The telescopic end of the first hydraulic telescopic rod 17 is fixedly connected to the movable frame 16. A retaining ring 13 is fixedly connected to the side of the movable frame 16 facing the annular rotating box 3. Four arc-shaped grooves 12, adapted to the retaining rings 13, are provided on the side of the rotating disk 11 away from the rotating column 4. The four arc-shaped grooves 12 are evenly distributed circumferentially, and the retaining ring 13 is inserted into one of the arc-shaped grooves 12 on the rotating disk 11 near the center of the positioning ring 14. A plug-in rotator for driving the rotating disk 11 to rotate is installed on the positioning ring 14. The meshing components include a gear ring 18 rotatably installed inside the annular rotating box 3 and a rotating sleeve 8. The external fixed sleeve is equipped with a gear 19 located inside the annular rotating box 3, and the gear 19 meshes with the gear ring 18. The plug-in type rotator includes a motor frame 20 set on the side of the positioning ring 14 away from the annular rotating box 3. Several second hydraulic telescopic rods 21 are fixedly connected to the positioning ring 14. The telescopic ends of the second hydraulic telescopic rods 21 are fixedly connected to the motor frame 20. A first servo motor 22 is fixedly connected to the motor frame 20. A plug block 23 is fixedly connected to the output end of the first servo motor 22. A slot 24 adapted to the plug block 23 is opened on the side of the rotating disk 11 away from the rotating column 4. When it is necessary to move the rotating column 4 relative to the rotating sleeve 8 and the annular rotating box 3, the positioning ring 14 is moved by the third hydraulic telescopic rod 30. The positioning ring 14 drives the rotating column 4 and the first guide strip 10 to slide relative to the first guide groove 9 and the rotating sleeve 8 through the rotating disk 11, so that the rotating column 4 can move relative to the annular rotating box 3. When it is necessary to remove the clamped and fixed aluminum alloy plate, the third hydraulic telescopic rod 30 drives the positioning ring 14 and the rotating column 4 to translate again. The friction between the prism 6 and the slide groove 7 is less than the friction between the aluminum alloy plate and the accommodating chamber of the clamping seat 5. As the rotating column 4 translates, the rotating column 4 slides relative to the prism 6, and the clamping seat 5 remains stationary relative to the aluminum alloy plate. When the distance between two adjacent rotating columns 4 increases to a preset value, The operator drives the prism 6 and the clamping seat 5 to slide relative to the aluminum alloy sheet, increasing the length of the prism 6 within the slide groove 7, thereby increasing the distance between two adjacent clamping seats 5. This allows the end of the aluminum alloy sheet to slide out of the receiving cavity of the clamping seat 5, completing the removal of the aluminum alloy sheet. Initially, the insertion ring 13 is inserted into an arc-shaped groove 12 on the rotating disk 11 near the center of the positioning ring 14. When the drive mechanism drives the annular rotating box 3 to rotate, the annular rotating box 3 drives the rotating column 4 and the rotating sleeve 8 to revolve. The rotating column 4 drives the rotating disk 11 to move synchronously. The arc-shaped groove 12 on the rotating disk 11 slides relative to the insertion ring 13, and the end of the rotating disk 11 away from the center of the positioning ring 14 slides within the annular groove 15. Through the cooperation of the insertion ring 13 and the arc-shaped groove 12... To ensure that the rotating disk 11 and the rotating column 4 remain fixed relative to the annular rotating box 3, preventing the clamping seat 5 and the aluminum alloy plate from rotating and wobbling relative to the annular rotating box 3, when it is necessary to drive the aluminum alloy plate and the clamping seat 5 to rotate, the drive mechanism drives the annular rotating box 3 to rotate, so that one of the corresponding slots 24 rotates to one side of the insert block 23. The second hydraulic telescopic rod 21 drives the motor frame 20 and the first servo motor 22 to move. The first servo motor 22 drives the insert block 23 to insert into the slot 24. At this time, the first hydraulic telescopic rod 17 drives the movable frame 16 and the insert ring 13 to move, so that the insert ring 13 is no longer inserted into the arc groove 12. The first servo motor 22 drives the insert block 23 to rotate, and the insert block 23 can then drive the rotating column 4 and the rotating disk 11 to rotate. The first guide bar 10 rotates, which in turn drives the gear 19 to rotate via the rotating sleeve 8. The gear 19 drives the other gears 19 to rotate synchronously via the gear ring 18, thus causing the other rotating columns 4 and clamping seats 5 to rotate synchronously. This allows several aluminum alloy plates to rotate and flip simultaneously. When the position of the aluminum alloy plates needs to be repositioned, the first hydraulic telescopic rod 17 drives the movable frame 16 and the insertion ring 13 to move in the opposite direction, so that the insertion ring 13 is inserted again into an arc-shaped groove 12 on the rotating disk 11 near the center of the positioning ring 14. Then, the second hydraulic telescopic rod 21 drives the motor frame 20 and the first servo motor 22 to move in the opposite direction, so that the first servo motor 22 drives the insertion block 23 to disengage from the slot 24, thus completing the rotation and flipping of the aluminum alloy plates.This also prevents the aluminum alloy sheet and clamping base 5 from rotating and wobbling relative to the annular rotating box 3.

[0024] Example 3, based on Example 1, is... Figure 1 , Figure 2 and Figure 9 The drive mechanism includes two support sleeves 25 rotatably mounted on the mounting frame 2, and two annular rotating boxes 3 are respectively fixedly sleeved on the outside of the two support sleeves 25. A second servo motor 26 is fixedly connected to the mounting frame 2. A first sprocket 27 is fixedly sleeved on the outside of one of the support sleeves 25. A second sprocket 28 is fixedly connected to the output end of the second servo motor 26, and the second sprocket 28 and the first sprocket 27 are connected by a chain 29. The drilling assembly includes a movable seat 43 slidably mounted on the mounting frame 2. A second lead screw 48 is rotatably connected to the mounting frame 2. The rod 48 and the movable seat 43 are connected by a threaded connection. A fifth servo motor 49 is fixedly connected to the mounting bracket 2, and the output end of the fifth servo motor 49 is fixedly connected to the end of the second lead screw 48. A slide plate 44 is slidably connected to the movable seat 43. A fourth hydraulic telescopic rod 45 is fixedly connected to the movable seat 43, and the telescopic end of the fourth hydraulic telescopic rod 45 is fixedly connected to the slide plate 44. A fifth hydraulic telescopic rod 46 is fixedly connected to the side of the slide plate 44 away from the movable seat 43, and a drilling mechanism 47 for drilling is fixedly connected to the telescopic end of the fifth hydraulic telescopic rod 46. The second servo motor 26 drives the second sprocket 28 to rotate, which in turn drives the first sprocket 27 and the support sleeve 25 to rotate via the chain 29. The support sleeve 25 drives the annular rotating box 3 to rotate, and the annular rotating box 3 drives another annular rotating box 3 and the support sleeve 25 to rotate relative to the mounting frame 2 via the clamping seat 5 and the aluminum alloy plate, so that the aluminum alloy plate to be drilled rotates to the drilling position. The fifth hydraulic telescopic rod 46 drives the drilling mechanism 47 to move toward the aluminum alloy plate, and the drilling mechanism 47 can drill holes in the aluminum alloy plate. The fourth hydraulic telescopic rod 45 drives the slide plate 44 and the fifth hydraulic telescopic rod 46 to slide relative to the movable seat 43, so that the vertical position of the drilling mechanism 47 can be adjusted. The fifth servo motor 49 drives the second lead screw 48 to rotate, and the second lead screw 48 drives the movable seat 43 to slide on the mounting frame 2, so that the horizontal position of the drilling mechanism 47 can be adjusted.

[0025] Example 4, based on Example 3, by Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 9As shown, a guide post 31 and a first lead screw 32 are rotatably connected to the mounting bracket 2. A third servo motor 33 and a fourth servo motor 34 are fixedly connected to both sides of the mounting bracket 2. The output end of the third servo motor 33 is fixedly connected to the end of the first lead screw 32, and the output end of the fourth servo motor 34 is fixedly connected to the end of the guide post 31. A first threaded sleeve 35 is fitted on the outside of the guide post 31. Several second guide grooves 36 are formed on the guide post 31. Several second guide bars 37 are fixedly connected to the inner wall of the first threaded sleeve 35, and the second guide bars 37 are located in the corresponding second guide grooves 36. A second threaded sleeve 38 is fitted on the outside of the first lead screw 32. A support part is fixedly connected to the second threaded sleeve 38. The support part and the first threaded sleeve 35 are rotatably connected by bearings. The second threaded sleeve 38 and the first lead screw 32 are connected by threads. The second threaded sleeve 38 is equipped with a support for supporting the position of the plate to be drilled. The support includes a translation frame 50 that is slidably sleeved on the outside of the second threaded sleeve 38, and the first threaded sleeve 35 passes through the translation frame 50. The first threaded sleeve 35 and the translation frame 50 are connected by threads. Rectangular holes 41 are opened on both sides of the translation frame 50. A guide frame 39 is fixedly connected to the second threaded sleeve 38. A support seat 40 for supporting the position of the plate to be drilled passes through the guide frame 39. Two movable columns 42 are fixedly connected to the support seat 40, and the two movable columns 42 are located in the two rectangular holes 41 respectively. When drilling is required on the sheet metal, the first lead screw 32 is driven to rotate by the third servo motor 33. The first lead screw 32 drives the second threaded sleeve 38 and the first threaded sleeve 35 to slide relative to the guide post 31. The second guide bar 37 slides in the second guide groove 36. The first threaded sleeve 35 and the second threaded sleeve 38 drive the translation frame 50 and the support base 40 to move synchronously to the position where drilling is required on the aluminum alloy sheet metal. When the support base 40 moves to the position where drilling is required on the aluminum alloy sheet metal, the third servo motor 33 stops driving the first lead screw 32 to rotate. The fourth servo motor 34 drives the guide column 31 to rotate. The guide column 31 drives the first threaded sleeve 35 to rotate through the second guide bar 37. The first threaded sleeve 35 drives the translation frame 50 to slide relative to the second threaded sleeve 38, so that the movable column 42 slides in the rectangular hole 41. The inner wall of the rectangular hole 41 pushes the support seat 40 to slide relative to the guide frame 39, so that the support seat 40 abuts against the side of the aluminum alloy plate away from the drilling mechanism 47. The support seat 40 supports the aluminum alloy plate and reduces the possibility of the aluminum alloy plate bending during the drilling process.

[0026] This embodiment also provides a drilling method for processing aluminum alloy sheets, applied to the drilling device for processing aluminum alloy sheets as described above, including the following steps: Step 1: According to the specifications of the aluminum alloy sheet, the staff selects a clamping seat 5 that matches the receiving chamber. The staff drives the clamping seat 5 to move so that the prism 6 is inserted into the corresponding slide groove 7. Step 2: After all the clamping seats 5 are installed, the worker drives the aluminum alloy plate that needs to be drilled to be placed between two adjacent clamping seats 5.

Step 3: After all the plates are installed, the rotating column 4 is driven to move horizontally by the clamping and flipping structure. The rotating column 4 and the slide 7 slide relative to the prism 6 until the end of the prism 6 away from the clamping seat 5 abuts against the inner wall of the slide 7, and the two ends of the aluminum alloy plate abut against the inner wall of the receiving chamber, so that the two adjacent clamping seats 5 clamp the aluminum alloy plate. Step 4: Drive the annular rotating box 3, clamping seat 5 and aluminum alloy plate to rotate through the drive mechanism, so that the clamping and flipping structure on the annular rotating box 3 drives the aluminum alloy plate that needs to be drilled to rotate to the drilling station in sequence through the rotating column 4 and clamping seat 5, and drills the aluminum alloy plate located at the drilling station through the drilling assembly. Step 5: When it is necessary to drill holes on the side of the aluminum alloy sheet, the clamping and flipping structure drives several rotating columns 4 to rotate. The rotating columns 4 drive the clamping seat 5 and the aluminum alloy sheet to rotate, so that the side of the aluminum alloy sheet faces the drilling assembly. The driving mechanism drives the annular rotating box 3 to rotate, so that the aluminum alloy sheet to be drilled rotates to the drilling station in sequence. The drilling assembly drills holes in the aluminum alloy sheet located at the drilling station.
