Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and in particular to a boring machine for drilling small holes on the top of an indexing plate. Background Technology

[0002] The field of metal processing technology encompasses a complete range of processes, including material handling, forming, machining, and surface treatment. It uses various processing techniques and equipment to process metal materials to obtain metal parts that meet usage requirements. The field of metal processing technology covers a variety of processing methods, among which cutting technology is one of the core branches, including specific processing forms such as turning, milling, planing, grinding, and drilling. Milling machines, as important cutting equipment, can process structures such as planes, grooves, and holes on metal workpieces and are widely used in many fields such as aerospace, automotive manufacturing, and electronic equipment.

[0003] One type of milling machine for drilling small holes on the top of an indexing plate is a specialized milling machine used for drilling small holes on the top of an indexing plate. It encompasses the drilling positioning of the small holes on the top of the indexing plate, the adaptation and installation of the indexing plate and the milling machine, the selection and installation of drilling tools, and the control of the drilling process. This includes setting up an installation structure adapted to the indexing plate on the milling machine body, driving the indexing plate to rotate via a worm gear pair, achieving precise indexing by relying on the cooperation of positioning pins and positioning holes on the indexing plate, and locking the indexing plate after each indexing. The milling machine spindle drives the drill bit to rotate, and by adjusting the spindle speed and feed rate, the drill bit is fed vertically to drill small holes at preset positions on the top of the indexing plate. Simultaneously, the position of the worktable can be adjusted manually or mechanically to ensure accurate drilling positioning.

[0004] Existing technologies use a single locating pin and locating hole to achieve indexing and positioning. This single clamping and positioning method has poor adaptability to different sizes of indexing plates. Workpiece position deviation is prone to occur during clamping. Only a single hole drilling operation can be completed in a single machining operation, resulting in low machining efficiency. There is no synchronous tool cooling and chip removal mechanism during the drilling process, which makes the tool prone to overheating and wear. Machining accuracy is easily affected by scattered chips. The connection stability between indexing and drilling is insufficient, which easily leads to indexing deviation. There are no positioning and holding measures during workpiece transfer, which easily leads to workpiece displacement, affecting the final machining accuracy and finished product qualification rate.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 8 as well as Figure 9As shown, a boring machine for drilling small holes on the top of an indexing plate includes a base 1. A worktable 2 is fixedly connected to the upper end of the base 1. The worktable 2 is the core working platform of the equipment, used to install and support a transport mechanism 3 and a cooling mechanism 4. The transport mechanism 3 is slidably connected to the middle of the upper end of the worktable 2 for protection. The transport mechanism 3 can not only transport the blank plate 33, but also position and fix the blank plate 33 to prevent it from shifting or being damaged during transportation and processing. The cooling mechanism 4 is fixedly connected to the right side of the worktable 2. The cooling mechanism 4 is mainly used to cool the milling cutter 5228 during processing. At the same time, it works with the collection mechanism 6 to complete the extraction and filtration of waste chips to prevent the milling cutter 5228 from wearing due to high temperature. The bottom of the cooling mechanism 4 is fixed. The base 1 is connected to a processing mechanism 5, which can adjust the drilling angle and position according to processing requirements to complete the drilling operation. A collection mechanism 6 is fixedly connected to the right side of the inner cavity of the base 1. The collection mechanism 6 is used to collect the waste generated during the processing, keep the working environment clean, and prevent the accumulation of waste from affecting the operation of the equipment and the processing accuracy. The right side of the collection mechanism 6 is connected to the cooling mechanism 4 to ensure that the cooling mechanism 4 can smoothly extract the waste from the collection mechanism 6 and complete the filtration. The processing mechanism 5 includes two fixed plates 51, which are symmetrically fixed to each other. The two fixed plates 51 are slidably connected to a sliding component 52 on the side close to each other. The sliding component 52 is used to adjust the drilling angle of the blank plate 33. The drilling position can be flexibly adjusted to meet the processing requirements of different specifications of blank disc 33. The sliding component 52 includes an I-beam 521, which serves as the main structure of the sliding component 52 and is used to install components such as the adjusting component 522 and telescopic rods 523, playing a connecting and load-bearing role. The adjusting component 522 is fixedly connected to the middle of the I-beam 521. The adjusting component 522 can adjust the position and angle of the milling cutter 5228 to realize drilling processing at different positions of the blank disc 33. Four telescopic rods 523 are fixedly connected to the bottom of the I-beam 521. The four telescopic rods 523 extend and retract synchronously, which can drive the I-beam 521 to move up and down, thereby driving the milling cutter 5228 to move closer to or away from the blank disc 33, completing the feed and reset of the drilling operation. A connecting rod 524 is fixedly connected to the rear left side of the I-beam plate 521. The connecting rod 524 connects the I-beam plate 521 and the rack 525, ensuring that the up and down movement of the I-beam plate 521 can be synchronously transmitted to the rack 525. The rack 525 is fixedly connected to the bottom of the connecting rod 524. The rack 525 cooperates with the one-way wheel 26, which can drive the one-way wheel 26 to rotate during the rise of the I-beam plate 521, thereby adjusting the angle of the transport mechanism 3 and realizing the indexing drilling of the blank plate 33. Four connecting strips 526 are fixedly connected to the upper end of the adjusting component 522. The four connecting strips 526 fix and support the air pump 43, ensuring the stability of the air pump 43 during operation. The upper ends of the four connecting strips 526 are fixedly connected to the bottom of the air pump 43.

[0035] Please see Figure 2 and Figure 3 As shown, the workbench 2 includes a support plate 21. Two reset blocks 22 are fixedly connected to the upper left side of the support plate 21. The two reset blocks 22 are symmetrically arranged. A motor 23 is fixedly connected to the left end of the support plate 21. A threaded rod 24 is fixedly connected to the output end of the motor 23. The threaded rod 24 cooperates with the gear barrel 324. When the motor 23 starts, it drives the threaded rod 24 to rotate, thereby driving the gear barrel 324 to move, realizing the overall movement of the transport mechanism 3. Two fixing strips 25 are fixedly connected to the bottom right side of the support plate 21. A one-way wheel 26 is fixedly and rotatably connected to the bottom of the two fixing strips 25. The one-way wheel 26 cooperates with the rack 525 and the mating gear 327. Only the rack When 525 rises, it drives the mating gear 327 to rotate, thereby adjusting the angle of the transport mechanism 3 to achieve indexing drilling of the blank disc 33. This prevents the transport mechanism 3 from rotating unexpectedly during the drilling process. The middle of the bearing plate 21 has a sliding groove 27 that cooperates with the transport mechanism 3. The sliding groove 27 provides guidance for the movement of the transport mechanism 3, ensuring that the transport mechanism 3 can move smoothly along a fixed trajectory and avoid deviation during the movement, which would affect the processing accuracy. A positioning ring 28 is fixedly connected to the upper right side of the bearing plate 21. The positioning ring 28 is used to position the movement of the transport mechanism 3, ensuring that the transport mechanism 3 can move accurately to the processing position and guarantee the accuracy of the drilling operation.

[0036] Example 2 further elaborates on the purpose of positioning and clamping the blank disc 33 based on Example 1. Please refer to Example 2. Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, the transport mechanism 3 includes a mating disc 31 for placing and positioning the blank disc 33. A suction component 32 is fixedly connected to the bottom of the mating disc 31. The suction component 32 can not only cooperate with the guide rail 63 to realize the smooth movement of the transport mechanism 3, but also generate negative pressure to fix the blank disc 33 for a second time, enhancing the stability of the blank disc 33. The bottom of the suction component 32 cooperates with the collection mechanism 6 to facilitate the smooth discharge and collection of waste chips during the processing. The blank disc 33 is fixedly clamped to the upper end of the mating disc 31. A preset hole is opened at the upper end of the blank disc 33. The preset hole is used for auxiliary positioning, which makes it easy for the milling cutter 5228 to accurately find the drilling position, improving drilling efficiency and accuracy.

[0037] Please see Figure 5 and Figure 6As shown, the mating disc 31 includes a disc 311, with a gear ring 312 rotatably connected to the upper end of the disc 311. A groove is formed on one side of the outer surface of the gear ring 312, which engages with the transmission assembly 314, allowing the power of the transmission assembly 314 to be smoothly transmitted to the gear ring 312. Four positioning components 313 for positioning and clamping the blank disc 33 are engaged on the inner surface of the gear ring 312. The four positioning components 313 are evenly distributed, enabling synchronous clamping of the blank disc 33 from four directions, ensuring uniform force on the blank disc 33 and preventing clamping. During the process, deformation occurs, and precise positioning is achieved. The left side of the disc 311 is rotatably connected to the transmission component 314. The transmission component 314 serves as the power source for the rotation of the gear ring 312. By operating the transmission component 314, the operator can drive the gear ring 312 to rotate, thereby controlling the clamping and releasing of the positioning component 313. When the transmission component 314 rotates, it can cooperate through the groove, so that the positioning component 313 can position and clamp the blank disc 33, ensuring the stability and accuracy of power transmission and ensuring the smooth progress of the clamping operation.

[0038] Please see Figure 6 As shown, the positioning component 313 includes a sliding block 3131. A threaded rod 3133 is threadedly connected to the bottom of the sliding block 3131. The threaded rod 3133 is rotatably connected to the disc 311. When the threaded rod 3133 rotates, it drives the sliding block 3131 to slide along the disc 311 through threaded transmission, thereby moving the sliding block 3131 closer to or further away from the disc, thus completing the clamping and releasing of the blank disc 33. Two rotating wheels 3132 are rotatably connected to the upper part of the other side of the sliding block 3131. The rotating wheels 3132 can reduce the friction between the sliding block 3131 and the blank disc 33, avoiding scratching the surface of the blank disc 33 during clamping. At the same time, when the blank disc 33 needs to be finely adjusted, it can assist the blank disc 33 in rotating, improving the processing flexibility.

[0039] Please see Figure 7As shown, the transmission assembly 314 includes a force-applying rod 3141. The right side of the force-applying rod 3141 is rotatably connected to the disk 311, ensuring that the force-applying rod 3141 can rotate stably on the disk 311. A fixed shell 3142 is rotatably connected to the outer surface of the force-applying rod 3141. The fixed shell 3142 serves to fix and support the transmission rod 3144, ensuring that the transmission rod 3144 can rotate stably and transmit power. Two transmission rods 3144 are rotatably connected to the upper part of the fixed shell 3142. The two transmission rods 3144 and the outer surface of the force-applying rod 3141 are connected together. A transmission belt 3143 is wound around the rod and connected to transmit power to the force-adjusting rod 3141. When the force-adjusting rod 3141 rotates, it drives the two transmission rods 3144 to rotate synchronously, ensuring the synchronicity of power transmission. Both transmission rods 3144 mesh with the gear ring 312. When the transmission rods 3144 rotate, they drive the gear ring 312 to rotate through gear meshing, thereby controlling the positioning component 313 to clamp the blank disc 33. This transmission method ensures stable power transmission, can ensure the smooth rotation of the gear ring 312, and improves the clamping accuracy.

[0040] Please see Figure 4 and Figure 5As shown, the suction assembly 32 includes a movable wheel 321. The bottom of the movable wheel 321 cooperates with the collection mechanism 6 and can roll along the guide rail 63 to realize the overall movement of the transport mechanism 3. At the same time, the up and down sliding of the movable wheel 321 can control the air pressure inside the gear barrel 324. A piston rod 322 is rotatably connected to the upper part of the movable wheel 321. The piston rod 322 can slide up and down under the drive of the movable wheel 321, thereby changing the volume of the gear barrel 324 and realizing the generation of negative pressure. A spring is wound around the outer surface of the piston rod 322. 323, spring 323 has good resilience, which can drive the moving wheel 321 to always be in contact with the guide rail 63, ensuring that the moving wheel 321 can roll stably, while ensuring the stability of the negative pressure generation. A gear barrel 324 is slidably connected to the upper part of spring 323. The gear barrel 324 is not only used to cooperate with the threaded rod 24 to realize the movement of the transport mechanism 3, but also serves as a cavity for generating negative pressure. The internal air pressure is changed by the sliding of piston rod 322. A fixing plate 325 is fixedly connected to the outer surface of gear barrel 324. 5 serves to connect the gear barrel 324 and the second fixing plate 326, ensuring the stable installation of the second fixing plate 326. The upper end of the first fixing plate 325 is fixedly connected to the second fixing plate 326. The second fixing plate 326 is used to fix and support the mating gear 327, ensuring that the mating gear 327 can rotate stably. The upper part of the second fixing plate 326 is rotatably connected to the mating gear 327. The mating gear 327 cooperates with the one-way wheel 26 and the gear ring 312, and can rotate under the drive of the one-way wheel 26, thereby adjusting the angle of the gear ring 312 to achieve... The indexing drill hole of the blank disc 33 is fixedly connected to the upper part of the gear barrel 324 with an air extraction disc 329. The air extraction disc 329 is used to collect the negative pressure generated by the gear barrel 324 and transmit the negative pressure to the connecting pipe 328. Four connecting pipes 328 are fixedly connected to the upper part of the air extraction disc 329 for secondary fixation of the blank disc 33. The four connecting pipes 328 are evenly distributed and can evenly transmit the negative pressure to the bottom of the blank disc 33 to perform secondary fixation of the blank disc 33, avoid the blank disc 33 from shaking during the drilling process, and improve the drilling accuracy.

[0041] Furthermore, the collecting mechanism 6 includes a collecting chamber 61, which is used to collect waste generated during the processing. Its upper part is fixedly connected to the bottom right side of the support plate 21, and can directly receive the waste falling from the support plate 21 to prevent the waste from scattering. A collecting box 62 is fixedly connected to the bottom of the collecting chamber 61. The collecting box 62 is used to store the collected waste, which is convenient for operators to clean regularly and keep the equipment clean. The inner cavity of the collecting chamber 61 is connected to the input pipe 45 to ensure that the cooling mechanism 4 can smoothly extract the waste and air in the collecting chamber 61 to achieve the filtration and collection of waste. A guide rail 63 is fixedly connected to the left side of the collecting box 62. The guide rail 63 is used to cooperate with the moving wheel 321 to ensure that the transport mechanism 3 can move smoothly along the fixed track. At the same time, the concave and convex structure of the guide rail 63 can make the moving wheel 321 slide up and down to help generate negative pressure and enhance the fixing effect of the blank plate 33.

[0042] Example 3 further elaborates on how to drill holes in the blank disc 33 and achieve chip removal, based on Example 2. Please refer to [link / reference]. Figure 8 , Figure 9 as well as Figure 10 As shown, the cooling mechanism 4 includes a blocking box 41, which filters and blocks the extracted waste debris to prevent fine debris from entering the air pump 43, damaging its components, and extending its service life. A delivery pipe 42 is fixedly connected to the output end of the blocking box 41, which delivers the filtered air to the air pump 43, ensuring it can properly draw in air. The air pump 43 is fixedly connected to the other side of the delivery pipe 42, serving as the power source for the cooling mechanism 4. It extracts waste debris and air from the collection mechanism 6 and simultaneously delivers the filtered air to the air supply pipe 44. Four air supply pipes 44 are fixedly connected to the output end of the 43. The four air supply pipes 44 are used to cool the machining mechanism 5. They can accurately target the milling cutter 5228 and remove the heat generated by the milling cutter 5228 during machining in time, so as to avoid the milling cutter 5228 from annealing or wear due to high temperature, and ensure the machining accuracy and service life of the milling cutter 5228. The input end of the blocking box 41 is fixedly connected to the input pipe 45. The input pipe 45 is used to transport the waste chips and air in the collection mechanism 6 to the blocking box 41 to achieve the filtration and collection of waste chips. The other side of the input pipe 45 is connected to the inner cavity of the collection mechanism 6 to ensure that the waste chips and air can smoothly enter the blocking box 41.

[0043] It should be noted that the blocking box 41 mentioned above is a conventional technical means in the prior art, used to handle iron filings and impurities and to prevent the air pump 43 from being affected. Its working principle and circuit connection will not be elaborated in this solution.

[0044] Please see Figure 9As shown, the adjustment assembly 522 includes a housing 5221. A second motor 5222 is fixedly connected to the upper end of the housing 5221. A rotating disk 5223 is fixedly connected to the output end of the second motor 5222. The rotating disk 5223 is rotatably connected to the inner cavity of the housing 5221. Four arc-shaped grooves 5224 are formed on the surface of the rotating disk 5223. These grooves guide the sliding rod 5225. When the rotating disk 5223 rotates, the sliding rod 5225 slides along the arc-shaped grooves 5224, thus retracting or extending the sliding rod 5225. Sliding rods 5225 are slidably connected to the inner surfaces of all four rotating disks 5223. The sliding rods 5225 are used to mount a third motor 5226 and... The milling cutter 5228 can be retracted or extended to adjust the spacing of the milling cutter 5228 to meet the drilling requirements of blank discs 33 of different specifications. The upper part of the four sliding rods 5225 on the side away from each other is fixedly connected to the motor 3 5226. The motor 3 5226 serves as the power source for the milling cutter 5228, driving the milling cutter 5228 to rotate and realize the drilling of the blank disc 33. The output end of the motor 3 5226 is fixedly connected to the milling cutter 5228. The four sliding rods 5225 on the side away from each other are fixedly connected to the lugs 5227. The four lugs 5227 are used to fix the four air supply pipes 44 to ensure that the air supply pipes 44 can be stably aligned with the milling cutter 5228 and ensure the cooling effect.

[0045] Working principle: In operation, the blank disc is first placed on the mating disc 31 of the transport mechanism 3. The force-applying rod 3141 of the transmission assembly 314 is rotated. The force-applying rod 3141 drives the two transmission rods 3144 on the fixed housing 3142 to rotate synchronously via the transmission belt 3143. The transmission rods 3144 mesh with the gear ring 312, thereby driving the gear ring 312 to rotate. During the rotation of the gear ring 312, the internal teeth drive the four threaded rods 3133 to rotate synchronously. Simultaneously, the four threaded rods... When lever 2 3133 rotates, it will cause the sliding blocks 3131 connected by threads on the outer surface to move closer together, thereby positioning and clamping the blank disc 33. Subsequently, motor 1 23 will start, and through the fixed connection of motor 1 23 to the output end, it will cooperate with gear barrel 324 to drive the entire transport mechanism 3 to move to the right. Furthermore, during the movement of the entire transport mechanism 3 to the right, the moving wheel 321 at its bottom will cooperate with guide rail 63. After reaching the appropriate stroke position, spring 323 will drive the mechanism through its own elasticity. The movable wheel 321 is kept in contact with the guide rail 63. During the contact process, the movable wheel 321 slides downward, thereby drawing air out of the gear barrel 324 to create negative pressure, which in turn provides secondary fixation to the blank disc 33 placed on the upper part of the connecting pipe 328, preventing shaking when drilling holes in the surface of the blank disc 33. Furthermore, after the suction assembly 32 reaches the appropriate position, the rear of the gear 327 engages with the front of the one-way wheel 26. Then, the four telescopic rods 523 drive the I-beam 521 downward. When drilling the blank disc 33, the connecting rod 524, which is fixedly connected to the left side of the rear of the I-beam 521, will drive the rack 525 to engage with the one-way wheel 26. When descending, it will not drive the engaging gear 327 to rotate. After drilling is completed and the plate rises to a safe position, it continues to rise. Then the rack 525 will engage with the one-way wheel 26 and drive it to rotate. Furthermore, during the rotation of the one-way wheel 26, it will drive the engaged gear 327 to rotate and adjust the angle. This process continues until drilling is completed.

[0046] Furthermore, during the drilling process, the air pump 43 is started and, through the cooperation of the delivery pipe 42, the blocking box 41 and the input pipe 45, the waste chips are extracted from the inner cavity of the collection box 62 fixedly connected to the bottom of the support plate 21. During the extraction process, the blocking box 41 will filter and block the fine waste chips. Then the air pump 43 will discharge the output air through the four air supply pipes 44 and cool the four milling cutters 5228.

[0047] After drilling one cycle, the operator can start motor 2 5222 according to the actual situation. During the start-up process of motor 2 5222, it will drive the rotating disk 5223 to make fine adjustments, and then drive the rotating disk 5223 to rotate. During the rotation of the rotating disk 5223, it will drive the four sliding rods 5225 to retract or extend. The operator can adjust according to the actual situation.
