Technical Field
[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to an improved structure of a drilling device for automotive parts manufacturing. Background Technology
[0002] Automotive parts are the various independent units that make up a complete vehicle. They work together through assembly, welding, and connection to enable the vehicle to have functions such as driving, steering, braking, safety protection, and comfort. Drilling equipment for automotive parts production is a mechanical device specifically used to process holes in automotive parts. Its core function is to remove excess material from the material by rotating cutting tools (such as drill bits, reamers, etc.) to form holes that meet design requirements. This type of device is widely used in automobile manufacturing, covering the processing of key components such as engines, transmissions, chassis, and bodies.
[0003] In existing technologies, automotive parts design specifications often require two or more even-numbered mounting holes, which are typically distributed symmetrically in pairs at critical connection points to ensure balanced stress and structural stability during assembly. However, current mainstream drilling equipment generally uses a single drill bit for hole-by-hole machining, which requires frequent adjustments to the drill bit path to complete the machining of symmetrical holes. This not only significantly increases the idle travel time of the equipment but also affects the positional accuracy of the hole system due to accumulated errors from repeated positioning, ultimately limiting overall processing efficiency and product qualification rate. Therefore, it is necessary to improve the structure of drilling equipment for automotive parts production to solve the above problems. Utility Model Content

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figure 1 - Figure 6This utility model provides an embodiment of an improved structure for a drilling device used in automotive parts production, comprising a workbench 1, a support frame 28 fixedly connected to the top of the workbench 1, a lifting frame 211 slidably connected inside the support frame 28, an air blowing assembly disposed on one side of the lifting frame 211, a hydraulic telescopic rod 212 fixedly connected to the side of the lifting frame 211 away from the air blowing assembly, a gear 214 rotatably connected to the lifting frame 211, a toothed plate 213 slidably connected inside the lifting frame 211, and a gear 214 slidably connected inside the lifting frame 211. The sliding frame 215, the connecting bracket 216 fixedly connected between the toothed plate 213 and the sliding frame 215, the third motor 217 fixedly connected inside the sliding frame 215, the tool holder 218 fixedly connected to the output end of the third motor 217, the drill body 219 fixedly connected to the bottom of the tool holder 218, the telescopic end of the hydraulic telescopic rod 212 fixedly connected to the side of the toothed plate 213 away from the gear 214, the toothed plate 213 meshing with the outside of the gear 214, the connecting bracket 216 slidably connected inside the lifting frame 211, and the tool holder 218 rotatingly connected... The drill bit body 219 is rotated by a third motor 217 via a tool holder 218 inside the sliding frame 215. A gear plate 213 meshes with the gear 214 and moves the sliding frame 215 via a connecting bracket 216. This design of two symmetrically distributed sliding frames 215 allows for the simultaneous installation of two drill bit bodies 219, enabling simultaneous drilling of automotive parts and significantly improving drilling efficiency. The meshing transmission between the gear plate 213 and the gear 214, and then the connecting bracket 216, further drive the sliding frame 215. The movement enables precise displacement adjustment of the drill bit body 219, ensuring the accuracy of the drilling position, meeting the drilling needs of different automotive parts, improving overall processing efficiency and product qualification rate. The air blowing assembly generates airflow through the blower 31, which can be precisely guided to the drilling position through the universal adjustment tube 33 and the blower head 34, promptly blowing away the debris generated during the drilling process, preventing debris from accumulating at the drilling site and affecting drilling accuracy. It also prevents debris from adhering to the drill bit body 219, reducing drill bit wear and extending the service life of the drill bit.
[0025] Please see Figure 2 - Figure 5In this embodiment, the support frame 28 has a matching limiting groove at the corresponding position of the lifting frame 211. The lifting frame 211 slides inside the limiting groove of the support frame 28. The limiting groove on the support frame 28 matches the lifting frame 211, so that the lifting frame 211 is strictly limited during sliding, avoiding the lifting frame 211 from deviating or shaking when moving up and down, ensuring the linearity and stability of the movement of the lifting frame 211, thereby ensuring the vertical movement accuracy of the drill bit body 219 installed on the lifting frame 211, reducing drilling errors caused by the shaking of the lifting frame 211, and improving the drilling quality of automotive parts. The lifting frame 211 has a matching limiting groove at the corresponding position of the toothed plate 213. Plate 213 slides within the limiting groove of lifting frame 211, and lifting frame 211 has a corresponding matching through groove at the corresponding position of connecting frame 216. Connecting frame 216 slides within the through groove of lifting frame 211. The limiting groove of lifting frame 211 for toothed plate 213 can accurately guide the sliding direction of toothed plate 213, preventing toothed plate 213 from tilting during sliding, ensuring the stability of meshing between toothed plate 213 and gear 214, and ensuring that transmission efficiency is not affected. The sliding of connecting frame 216 within the through groove of lifting frame 211 further restricts the movement trajectory of connecting frame 216, making the movement of sliding frame 215 more stable when connected frame 216 drives sliding frame 215, avoiding unnecessary shaking of sliding frame 215, thereby The design ensures the horizontal movement accuracy of the drill bit body 219, which helps improve the accuracy of the drilling position. Two sliding frames 215 are provided, symmetrically distributed on the outer side of the toothed plate 213. The lifting frame 211 has matching limiting grooves at corresponding positions of the two sliding frames 215. Both sliding frames 215 slide within the limiting grooves of the lifting frame 211. This symmetrically distributed sliding frame 215 design allows for the simultaneous installation of two drill bit bodies 219, enabling simultaneous drilling of automotive parts and greatly improving drilling efficiency. It is particularly suitable for the production of parts requiring multiple drilling operations. Simultaneously, the limiting grooves on the lifting frame 211 limit the movement of the two sliding frames 215, ensuring their proper positioning. The synchronization and stability of the movement avoid drilling errors caused by the offset of a single sliding frame 215, ensuring the positional accuracy and consistency between multiple drill holes. A first motor 21 is fixedly connected to one side of the worktable 1. A bidirectional threaded rod 22 is fixedly connected to the output end of the first motor 21. The bidirectional threaded rod 22 is rotatably connected inside the worktable 1. A clamping frame 23 is slidably connected inside the worktable 1. The clamping frame 23 is threadedly connected to the outside of the bidirectional threaded rod 22. A fixing sleeve 24 is fixedly connected inside the clamping frame 23. A clamping pin 25 is slidably connected inside the fixing sleeve 24. The clamping pin 25 is slidably connected inside the clamping frame 23. A limiting plate 26 is fixedly connected to one end of the clamping frame 23. The limiting plate 26 is slidably connected inside the clamping frame 23.A spring 27 is fixedly connected between the limiting plate 26 and the clamping frame 23. A second motor 29 is fixedly connected to the top of the support frame 28. A screw 210 is fixedly connected to the output end of the second motor 29. The screw 210 is rotatably connected inside the support frame 28. The lifting frame 211 is threadedly connected to the outside of the first motor 21. The first motor 21 drives the bidirectional threaded rod 22 to rotate, causing the two clamping frames 23 to slide relative to each other within the worktable 1, realizing automatic clamping of automotive parts without manual fixing, saving labor costs and improving the convenience of operation. Under the action of the spring 27 and the limiting plate 26, the clamping pin 25 inside the clamping frame 23 can automatically adjust the clamping force according to the shape of the parts, enabling clamping of irregularly shaped automotive parts while ensuring the stability of the clamping and improving the adaptability of the clamping. There are two clamping frames 23, which are symmetrically distributed on the bidirectional threaded rod 22, and the worktable 1 is positioned opposite the two clamping frames 23. The worktable 1 has a corresponding through groove at the corresponding position. Both clamping frames 23 slide within the through groove. Driven by the bidirectional threaded rod 22, the two symmetrically distributed clamping frames 23 can simultaneously clamp the workpiece from both sides, making the clamping force on the workpiece more uniform and preventing the workpiece from shifting due to uneven force. This ensures the stability of the workpiece during drilling. The through groove of the worktable 1 limits the sliding of the clamping frames 23, ensuring the synchronicity and linearity of the movement of the two clamping frames 23, further improving the clamping accuracy and providing a reliable foundation for high-quality drilling. The clamping frames 23 have corresponding sliding grooves at the corresponding positions of the limiting plate 26. The limiting plate 26 slides within the sliding grooves of the clamping frames 23. The sliding grooves on the clamping frames 23 are compatible with the limiting plate 26, providing a stable track for the sliding of the limiting plate 26. Under the action of the spring 27, the limiting plate 26 can smoothly drive the clamping pin 25 to move.
[0026] Please see Figure 1 , Figure 6In this embodiment, the air blowing assembly includes a blower 31 fixedly connected to the side of the lifting frame 211 away from the hydraulic telescopic rod 212, an air inlet 35 disposed on the blower 31, an air outlet 36 disposed on the blower 31, a universal adjusting pipe 33 fixedly connected to the air outlet 36, a blower head 34 fixedly connected to the end of the universal adjusting pipe 33 away from the air outlet 36, and a filter plate 32 fixedly connected to the air inlet 35. The blower 31 can generate airflow, and the universal adjusting pipe 33 and the blower head 34 can accurately guide the airflow to the drilling position, promptly blowing away the drill bit. The debris generated during the drilling process is prevented from accumulating at the drilling site and affecting drilling accuracy. It also prevents debris from adhering to the drill bit body 219, reducing drill bit wear and extending the service life of the drill bit. The filter plate 32 at the air inlet 35 can filter the air entering the blower 31, preventing impurities in the air from entering the blower 31, ensuring the normal operation of the blower 31, and extending the service life of the blowing assembly. The universal adjustment tube 33 allows the direction of the blower head 34 to be flexibly adjusted to adapt to different drilling positions and angles, improving the cleaning effect of air blowing.
[0027] During operation, the automotive parts to be processed are first placed in the center of the worktable 1. The operator then starts the first motor 21, which drives the bidirectional threaded rod 22 to rotate. Since the two clamping frames 23 are symmetrically threaded onto the outside of the bidirectional threaded rod 22 and slide within the through groove of the worktable 1, the rotation of the bidirectional threaded rod 22 causes the two clamping frames 23 to move synchronously towards the center. During clamping, after the clamping pin 25 contacts the part, it retracts inwards into the clamping frame 23. At this time, the limiting plate 26 slides within the groove of the clamping frame 23 and compresses the spring. 27. The reaction force of spring 27 pushes clamping pin 25 to firmly press against the component, achieving a stable clamping of the component and adapting to components of different shapes. Then, the operator activates the hydraulic telescopic rod 212 to extend and retract. The extension end of the hydraulic telescopic rod 212 pushes the toothed plate 213 to slide within the limiting groove of the lifting frame 211. Since the toothed plate 213 and gear 214 mesh with each other, the sliding of the toothed plate 213 will drive the gear 214 to rotate, thereby causing the toothed plates 213 on both sides to move synchronously in opposite directions. At the same time, the toothed plate 213 drives the two sliding parts through the connecting frame 216. The frame 215 slides within the limiting groove of the lifting frame 211, thereby adjusting the horizontal position of the two drill bit bodies 219 to meet drilling requirements at different locations. During drilling, the operator starts the third motor 217, which drives the drill bit body 219 to rotate at high speed via the tool holder 218, providing power for the drilling operation. Then, the operator starts the second motor 29, which drives the screw 210 to rotate. Because the lifting frame 211 is threaded onto the outside of the screw 210 and slides within the limiting groove of the support frame 28, the screw 210... The rotation of 0 causes the lifting frame 211 to move up and down along the limiting groove of the support frame 28, thereby moving the drill bit body 219 downward to drill the automotive parts. At the same time, the air blowing assembly works synchronously, generating airflow through the blower 31. Outside air enters the blower 31 after being filtered by the filter plate 32 of the air inlet 35, and then is delivered to the blower head 34 through the universal adjustment tube 33 from the air outlet 36. By adjusting the angle of the universal adjustment tube 33, the blower head 34 can be aligned with the drilling position to promptly blow away the debris generated during drilling, avoiding the debris from affecting the drilling accuracy or wearing out the drill bit.
[0028] Through the above steps, by using two symmetrically distributed sliding frames 215 to simultaneously mount two drill bit bodies 219, the drilling process is significantly accelerated, and the processing efficiency is effectively improved. Furthermore, the displacement of the drill bit body 219 is precisely controlled to ensure the accuracy of the drilling position. This improves the overall processing efficiency and increases the product qualification rate. This addresses the problem that automotive parts design typically requires symmetrically distributed even-numbered mounting holes to ensure balanced force distribution. However, the current single-drill-bit processing method requires repeated path adjustments, which increases idle travel time and reduces hole position accuracy due to repeated positioning, ultimately affecting processing efficiency and product qualification rate.
