Description

Technical Field

[0001] This utility model relates to the field of metal part drilling technology, specifically a metal part drilling device with automatic debris collection. Background Technology

[0002] Metal parts are basic industrial components manufactured from metal materials through processes such as casting, forging, machining, and 3D printing. They include steel structure parts. The various components of a steel structure are usually connected by bolts or rivets. Bolt and rivet connections usually require pre-drilling holes in the connecting plate, which requires a drilling device. The sharp drill bit in the drilling device rotates and cuts or rotates and extrudes to leave cylindrical holes or openings in the steel structure.

[0003] Chinese patent (authorization announcement number: CN 215657982 U, authorization announcement date: 2022.01.28) proposes a drilling device for steel structure parts with debris collection function. In this utility model, the device achieves stable clamping, improves work efficiency, avoids debris from affecting the working environment, and reduces the workload of workers. It is worth promoting.

[0004] Although the above-mentioned device uses a collection box and a wiping plate to collect debris, in practical applications, debris collection mainly relies on gravity to allow the debris to fall naturally into the collection box, and then the residual debris is cleaned by manually pulling the wiping plate. This not only has low collection efficiency, but also makes it difficult to completely collect the small and light debris generated during the drilling process, resulting in the working environment still being contaminated by debris. Therefore, we propose a drilling device for metal parts with automatic debris collection. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a metal parts drilling device with automatic debris collection, including a device housing 1, a dust collection chamber 12 is provided on the front side of the inner side of the device housing 1, an installation chamber 13 is provided between the top of the device housing 1 and the top of the dust collection chamber 12, a material discharge plate 20 is fixedly connected to the top of the inner side of the dust collection chamber 12, the bottom side of the material discharge plate 20 is flush with the bottom side of the installation chamber 13, a dust leakage hole 22 is provided through the middle of the material discharge plate 20, a collection box 2 is slidably installed on the front side of the inner side of the dust collection chamber 12, a clamping assembly is installed inside the installation chamber 13, a drilling assembly is installed on the top side of the installation chamber 13, and a negative pressure dust suction assembly is also installed between the collection box 2 and the drilling assembly.

[0023] When the metal part drilling device with automatic debris collection is working, the metal part to be drilled is first placed on the feeding plate 20 at the top of the inner side of the dust collection chamber 12. The part on the feeding plate 20 is clamped and fixed by the clamping assembly installed inside the mounting chamber 13. After the part is fixed, the drilling assembly installed on the top side of the mounting chamber 13 is started. The drilling assembly operates and drills the part. During the drilling process, some of the debris will fall into the collection box 2, which is slidably installed at the front of the dust collection chamber 12, through the dust leakage hole 22 in the middle of the feeding plate 20 under the action of gravity. At the same time, the negative pressure dust suction assembly installed between the collection box 2 and the drilling assembly is started synchronously to suck up the remaining debris generated by drilling and transport it to the collection box 2, thus realizing the operation process of simultaneous drilling and debris collection.

[0024] The clamping assembly includes two sets of sliding plates 14, which are slidably installed on the left and right sides of the mounting chamber 13. Screws 16 are also rotatably installed on both sides of the mounting chamber 13. The bottoms of the two sets of sliding plates 14 are threaded onto the two sets of screws 16. A second drive motor 23 is fixedly installed on the front right side of the mounting chamber 13. Bevel gears 24 are fixedly connected to the front end of the right-side screw 16 and the output shaft end of the second drive motor 23. The two sets of bevel gears 24 mesh with each other. The rear end of each screw 16 is fixedly connected to a synchronous pulley 17. A synchronous belt 18 is tensioned between the two sets of synchronous pulleys 17. A clamping cylinder 15 is fixedly installed on the top of each set of sliding plates 14. A sliding groove 19 is opened through the left and right sides of the mounting chamber 13. The output shafts of the two sets of clamping cylinders 15 slide through the sliding groove 19. The output shaft ends of the two sets of clamping cylinders 15 are fixedly connected to clamping plates 21. The bottom sides of the two sets of clamping plates 21 are slidably connected to the top side of the discharge plate 20.

[0025] When the clamping assembly is working, the second drive motor 23 installed on the right front side inside the installation chamber 13 is started first. The output shaft of the second drive motor 23 drives the bevel gear 24 fixedly connected to it to rotate. Since the two sets of bevel gears 24 mesh with each other, the right screw 16 rotates synchronously under the drive of the meshing bevel gears 24. Since the rear ends of the two sets of screws 16 are fixedly connected to the synchronous pulleys 17, and the synchronous belt 18 is tensioned between the two sets of synchronous pulleys 17, the right screw 16 drives the left screw 16 to rotate synchronously through the transmission action of the synchronous pulleys 17 and the synchronous belt 18. When the two sets of screws 16 rotate, the two sets of sliding plates 14, which are respectively threaded onto the two sets of screws 16, slide left and right inside the mounting chamber 13. The clamping cylinder 15, which is fixedly installed on the top of the sliding plate 14, also slides synchronously along the sliding groove 19 that runs through the left and right sides of the mounting chamber 13. After the clamping cylinder 15 moves to the position where the part is clamped, the clamping cylinder 15 drives the output shaft to extend, which drives the clamping plate 21, which is fixedly connected to the end of the output shaft, to slide on the top side of the feeding plate 20. Finally, the two sets of clamping plates 21 cooperate with each other to clamp and fix the part on the feeding plate 20.

[0026] The drilling assembly includes a fixed plate 3, with fixed rods 4 fixedly connected to the bottom left and right sides of the fixed plate 3. The bottom ends of the two sets of fixed rods 4 are fixedly connected to the top side of the installation chamber 13. A lifting plate 5 is provided below the fixed plate 3. The left and right parts of the lifting plate 5 are slidably sleeved on the two sets of fixed rods 4 respectively. A lifting cylinder 6 is fixedly installed in the middle of the top side of the fixed plate 3. The bottom output shaft end of the lifting cylinder 6 is fixedly connected to the top side of the lifting plate 5. A fixed frame 7 is fixedly connected in the middle of the bottom side of the lifting plate 5. A drive motor 8 is fixedly installed in the bottom side of the fixed frame 7. The output shaft end of the drive motor 8 rotates out of the bottom side of the fixed frame 7 and is fixedly installed with a drill bit 35. The bottom end of the drill bit 35 is directly opposite the dust leakage hole 22.

[0027] When the drilling assembly is working, the lifting cylinder 6 installed in the middle of the top side of the fixed plate 3 is activated first. The fixed plate 3 is stably installed on the top side of the installation chamber 13 by the fixed rods 4 fixedly connected to the left and right sides of the bottom. The bottom output shaft of the lifting cylinder 6 pushes the lifting plate 5 fixedly connected to it to slide down along the two sets of fixed rods 4. The fixed frame 7 fixedly connected to the middle of the bottom side of the lifting plate 5 moves down synchronously with the lifting plate 5. The drive motor 8 fixedly installed inside the bottom side of the fixed frame 7 also moves. At this time, the drive motor 8 is activated. The output shaft of the drive motor 8 rotates and drives the drill bit 35 extending from the bottom side of the fixed frame 7 to rotate at high speed. As the lifting cylinder 6 continues to push the lifting plate 5 down, the high-speed rotating drill bit 35 gradually approaches the part on the feeding plate 20. Since the bottom end of the drill bit 35 is directly opposite the dust leakage hole 22 in the middle of the feeding plate 20, the drill bit 35 finally contacts the part and completes the drilling operation.

[0028] The negative pressure dust collection assembly includes a fan 11, which is fixedly installed inside the left side of the device housing 1. Two sets of insertion pipes 28 are provided at the bottom rear side of the dust collection chamber 12. The input end of the fan 11 is fixedly connected to a negative pressure pipe 10, and the input end of the negative pressure pipe 10 is fixedly connected to the insertion pipe 28 located on the left side. Two sets of connection ports 26 are provided inside the rear side of the collection box 2, and the two sets of insertion pipes 28 are respectively inserted into the two sets of connection ports 26. A filter screen 27 is fixedly installed on the connection port 26 located on the left side, and the insertion pipe on the right side... A suction pipe 9 is fixedly connected to the upper part of the fixed frame 7, and a suction hood 33 is fixedly connected to the other end of the suction pipe 9. A fixed sleeve 31 is fixedly connected to the middle of the bottom side of the fixed frame 7, and the fixed sleeve 31 is fitted on the drill bit 35. The suction hood 33 is fitted on the outer surface of the fixed sleeve 31. A limiting plate 32 is fixedly fitted to the bottom end of the fixed sleeve 31. The top inner side of the suction hood 33 abuts against the top side of the limiting plate 32. A spring 34 is also fitted on the fixed sleeve 31. The two ends of the spring 34 abut against the fixed frame 7 and the suction hood 33 respectively.

[0029] A partition 25 is fixedly installed on the inner center of the collection box 2 by bolts, and two sets of connection ports 26 are located below the partition 25.

[0030] A sealing strip 29 is fixedly fitted onto the outer surface of the insertion tube 28, and a groove 30 is provided on the inner surface of the connection port 26, with the sealing strip 29 snapped into the groove 30.

[0031] When the negative pressure dust collection assembly is working, the fan 11, which is fixedly installed on the left side inside the device housing 1, is started first. The fan 11 generates negative pressure through the negative pressure pipe 10, which is fixedly connected to the input end. The input end of the negative pressure pipe 10 is fixedly connected to the left side insertion pipe 28, which is opened at the bottom of the rear side of the dust collection chamber 12. The two sets of insertion pipes 28 are respectively inserted into the two sets of connection ports 26 opened at the rear side inside the collection box 2. The sealing strip 29, which is fixedly sleeved on the outer surface of the insertion pipe 28, is engaged in the groove 30 on the inner surface of the connection port 26 to ensure the sealing of the negative pressure transmission. The negative pressure is transmitted to the collection box 2 through the left side insertion pipe 28. The inner middle of the collection box 2 is divided by a partition 25 fixedly installed with bolts, and both sets of connection ports 26 are located below the partition 25, so that the negative pressure acts stably on the lower part of the collection box 2. In the space, the suction pipe 9, which is fixedly connected to the right insertion tube 28, transmits negative pressure to the suction hood 33, which is fixedly connected to the other end. The suction hood 33 is fitted on the outer surface of the fixed sleeve 31, which is fixedly connected to the middle of the bottom side of the fixed frame 7. The fixed sleeve 31 is fitted on the drill bit 35. The limiting plate 32, which is fixedly fitted at the bottom end of the fixed sleeve 31, limits the suction hood 33. The two ends of the spring 34 fitted on the fixed sleeve 31 abut against the fixed frame 7 and the suction hood 33 respectively, so that the suction hood 33 can fit against the surface of the part. Finally, the debris generated by drilling is sucked into the suction hood 33 under the action of negative pressure, and enters the collection box 2 through the suction pipe 9 and the right insertion tube 28. The filter screen 27 fixedly installed on the left connection port 26 can prevent debris from entering the negative pressure pipe 10 and the fan 11, so as to achieve efficient collection of debris.

[0032] Working principle: When this metal part drilling device with automatic debris collection is working, the metal part to be drilled is first placed on the material discharge plate 20 on the top of the inner side of the dust collection chamber 12. Then, the drive motor 23 installed on the right front side inside the installation chamber 13 is started. The output shaft of the drive motor 23 drives the bevel gear 24 fixedly connected to it to rotate. Since the two sets of bevel gears 24 mesh with each other, the right screw 16 rotates synchronously under the drive of the meshing bevel gears 24. Since the rear ends of the two sets of screws 16 are fixedly connected to the synchronous pulleys 17, and the two sets of synchronous pulleys 17 are tensioned and sleeved with a synchronous belt 18, the right screw 16 rotates synchronously through the synchronous pulleys 18. The transmission action of 7 and synchronous belt 18 drives the left screw 16 to rotate synchronously; when the two sets of screws 16 rotate, the two sets of sliding plates 14, which are respectively threaded on the two sets of screws 16, slide on the left and right sides inside the mounting chamber 13. The clamping cylinder 15, which is fixedly installed on the top of the sliding plate 14, also slides synchronously along the sliding groove 19 that runs through the left and right sides of the mounting chamber 13. After the clamping cylinder 15 moves to the position where the part is clamped, the clamping cylinder 15 drives the output shaft to extend, which drives the clamping plate 21, which is fixedly connected to the end of the output shaft, to slide on the top side of the feeding plate 20. Finally, the two sets of clamping plates 21 cooperate with each other to clamp and fix the part on the feeding plate 20.

[0033] After the parts are fixed, the lifting cylinder 6 installed in the middle of the top side of the fixed plate 3 is activated. The fixed plate 3 is stably installed on the top side of the installation chamber 13 by the fixed rods 4 fixedly connected to the left and right sides of the bottom. The bottom output shaft of the lifting cylinder 6 pushes the lifting plate 5 fixedly connected to it to slide down along the two sets of fixed rods 4. The fixed frame 7 fixedly connected to the middle of the bottom side of the lifting plate 5 moves down synchronously with the lifting plate 5. The drive motor 8 fixedly installed inside the bottom side of the fixed frame 7 also moves. At this time, the drive motor 8 is activated. The output shaft of the drive motor 8 rotates and drives the drill bit 35 extending from the bottom side of the fixed frame 7 to rotate at high speed. As the lifting cylinder 6 continues to push the lifting plate 5 down, the high-speed rotating drill bit 35 gradually approaches the parts on the feeding plate 20. Since the bottom end of the drill bit 35 is directly opposite the dust leakage hole 22 in the middle of the feeding plate 20, the drill bit 35 finally contacts the parts and completes the drilling operation.

[0034] During the drilling process, some of the debris will fall under gravity through the dust leakage hole 22 in the middle of the discharge plate 20 into the collection box 2, which slides through the front of the dust collection chamber 12. At the same time, the fan 11, which is fixedly installed on the left side inside the device housing 1, is activated. The fan 11 generates negative pressure through the negative pressure pipe 10, which is fixedly connected to the input end. The input end of the negative pressure pipe 10 is fixedly connected to the left side insertion pipe 28 at the bottom of the rear side of the dust collection chamber 12. The two sets of insertion pipes 28 are respectively inserted into the two sets of connection ports 26 on the rear side of the collection box 2. The sealing strip 29 fixedly sleeved on the outer surface of the insertion pipe 28 is engaged in the groove 30 on the inner surface of the connection port 26 to ensure the sealing of the negative pressure transmission. The negative pressure is transmitted to the collection box 2 through the left side insertion pipe 28. The inner side of the collection box 2 is divided by a partition 25 fixedly installed with bolts in the middle. All interfaces 26 are located below the partition 25, so that the negative pressure acts stably on the lower space of the collection box 2. At the same time, the suction pipe 9, which is fixedly connected to the right side insertion pipe 28, transmits the negative pressure to the suction hood 33, which is fixedly connected to the other end. The suction hood 33 is fitted on the outer surface of the fixed sleeve 31, which is fixedly connected to the middle of the bottom side of the fixed frame 7. The fixed sleeve 31 is fitted on the drill bit 35. The limiting plate 32, which is fixedly fitted at the bottom end of the fixed sleeve 31, limits the suction hood 33. The two ends of the spring 34 fitted on the fixed sleeve 31 abut against the fixed frame 7 and the suction hood 33 respectively, so that the suction hood 33 can fit against the surface of the part. Finally, the debris generated by drilling is sucked into the suction hood 33 under the action of negative pressure, and enters the collection box 2 through the suction pipe 9 and the right side insertion pipe 28. The filter screen 27 fixedly installed on the left side connection port 26 can prevent debris from entering the negative pressure pipe 10 and the fan 11, so as to achieve efficient collection of debris.
