[0002] Precisely drilled holes at designated locations on automotive door hinges, meeting specifications to ensure the accuracy and stability of subsequent hinge installation. This equipment typically integrates positioning, drilling power systems, and control systems, improving drilling efficiency and precision through automated operation. It meets the standardized processing requirements for door hinge components in automotive manufacturing and is one of the key pieces of equipment for machining door hinge holes on automotive parts production lines.

[0003] Existing technology patent announcement number CN215746553U discloses a drilling device for automotive luggage compartment door hinges, including a machine body, an installation plate disposed within the machine body, and several vertical drilling stations disposed on the installation plate. A positioning plate is slidably connected to the machine body below the installation plate, a positioning component is disposed on the top surface of the positioning plate, and a driving component is disposed at the bottom of the machine body. The driving component is used to push the positioning plate closer to the installation plate. In use, a rotating rod is placed on the positioning component for positioning and fixation. The driving component can push the rotating rod to one side of the vertical drilling stations. During this process, several vertical drilling stations can be drilled in batches on the rotating rod. The operator only needs to control the pushing distance of the driving component to control the depth of the processed holes. This realizes the function of batch processing on the rotating rod, and the drilling device has the advantages of simple operation, reliable use, and high work efficiency.

[0004] In existing technologies, workpiece shaking during the use of grinding equipment may require frequent machine stops for adjustment during drilling, or even rework due to hole position deviation. At the same time, manual support of the workpiece is required, which increases the operational burden and makes it impossible to achieve batch automated processing. Utility Model Content

[0005] The purpose of this utility model is to provide a drilling device for automotive door hinges, which solves the problem of inconvenience in fixing the device, resulting in displacement and loss.

[0006] To achieve the above objectives, this utility model provides a drilling device for automotive door hinges, including a housing. A connecting mechanism is fixedly connected to the inner wall of the housing, a tabletop is fixedly connected to the top of the housing, a drilling mechanism is fixedly connected to the top of the tabletop, and a replacement assembly is fixedly connected to the outside of the drilling mechanism. The connecting mechanism includes a fixing plate, both ends of which are fixedly connected to the inside of the housing. A pneumatic cylinder is fixedly connected to the top of the fixing plate, and a connecting plate is fixedly connected to the driving end of the pneumatic cylinder. Two rotating plates are rotatably connected to both ends of the connecting plate, and a fixing assembly is rotatably connected to the outside of the rotating plates.

[0007] The drilling mechanism includes two fixed bases, the outer fixing plates of the two fixed bases are connected to the top of the desktop, the fixed bases are slidably connected to the outside of the fixed bases, and the inner side of the connecting blocks is fixedly connected to a motor.

[0008] The replacement component includes a protective cover, the top of which is fixedly connected to the drive end of the motor. A second pneumatic cylinder is fixedly connected to the inner wall of the protective cover. A follower plate is fixedly connected to the drive end of the second pneumatic cylinder. Multiple driven plates are rotatably connected to the outside of the follower plate. A sliding plate is rotatably connected to the drive end of the driven plate.

[0009] The bottom of the skateboard is fixedly connected to an auxiliary block, and a rubber block is fixedly connected to one of the adjacent sides of the multiple auxiliary blocks. A drill bit is movably connected to the outside of the rubber block.

[0010] The fixing component includes a clamping block, which is rotatably connected to the inside of the desktop. Two fixing rods are fixedly connected to the inner wall of the box, and the outside of each fixing rod is rotatably connected to the inner wall of the clamping block. A docking block is fixedly connected to the outside of the clamping block.

[0011] The clamping block is externally slidably connected to the inner wall of the desktop, and the connecting plate is externally slidably connected to the inner wall of the desktop.

Subsequently, the motor drives the connected drill bit to rotate at high speed, drilling the hinge. If a drill bit needs to be changed to fit different hinge specifications, the pneumatic cylinder drives the follower plate downwards, pulling the sliding plate and causing the auxiliary block to clamp the drill bit with a rubber block, achieving quick assembly and disassembly. This device ensures processing accuracy through clamping components and improves equipment versatility through component replacement. It reduces manual intervention, lowers safety risks, and efficiently completes standardized drilling processing of automotive door hinges. Attached Figure Description

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1 to 3This utility model provides an embodiment of a car door hinge drilling device, including a housing 1. A fixing plate 2 is fixedly connected to the inner wall of the housing 1. A pneumatic cylinder 3 is fixedly connected to the top of the fixing plate 2. After the pneumatic cylinder 3 is activated, it can drive a connecting plate 4 to move vertically. Two rotating plates 5 are rotatably connected to both ends of the connecting plate 4. When the connecting plate 4 moves up and down, the rotating plates 5 will swing around the rotating connection point as the axis. Two fixing rods 8 are also fixedly connected to the inner wall of the housing 1. A clamping block 6 is rotatably connected to the outside of the fixing rods 8. The clamping blocks 6 are clamped by the fixing rods 8. The rotation restriction at the end allows the clamping block 6 to be precisely moved towards the center under the push of the rotating plate 5, thereby clamping and fixing the car door hinge placed on the tabletop 9. This structure can reduce manual fixing steps, increase operational safety, and avoid problems such as hole position displacement, hole diameter error or tilting caused by workpiece shaking during drilling. It ensures that the drilling position, depth and angle of each hinge strictly meet the design standards. A grinding component is fixedly connected to the top of the housing 1, and a replacement component is fixedly connected to the outside of the grinding component to realize the quick replacement and grinding of the drill bit, improving the flexibility and efficiency of equipment processing.

[0023] like Figure 2 and Figure 4 The grinding assembly includes a tabletop 9, the bottom of which is fixedly connected to the top of the housing 1, providing a stable support platform for the entire processing operation. The top of the tabletop 9 is fixedly connected to two fixed bases 10, and a connecting block 11 is slidably connected to the outside of the fixed base 10. The connecting block 11 can move laterally along the guide structure of the fixed base 10 to adjust the drilling position. A motor 12 is fixedly connected to the inner wall of the connecting block 11. The drive end of the motor 12 is used to install the drill bit. The high-speed rotation of the motor 12 enables the drilling operation of the car door hinge.

[0024] The replacement component includes a protective cover 14, the top of which is fixedly connected to the drive end of the motor 12 and can rotate synchronously with the motor 12. It also protects the internal structure. A pneumatic cylinder 15 is fixedly connected to the inner wall of the protective cover 14. After the pneumatic cylinder 15 is started, it can drive the follower plate 16 to slide up and down in the inner wall of the protective cover 14. Multiple driven plates 17 are rotatably connected to the outside of the follower plate 16. When the follower plate 16 moves, the driven plates 17 will swing around the rotation connection point as the axis, thereby pulling the slide plate 18 to slide along the outer wall of the protective cover 14. This structure can achieve rapid clamping and release of the drill bit through the drive of the pneumatic cylinder 15, which is convenient for changing drill bits of different specifications. It enables the equipment to quickly adapt to various processing needs without the need to equip each hinge model with special drilling equipment, thus improving the versatility and processing flexibility of the equipment.

[0025] Auxiliary blocks 19 are fixedly connected to the bottom of the slide plate 18. Multiple auxiliary blocks 19 can move synchronously with the slide plate 18. Rubber blocks 20 are fixedly connected to the adjacent sides of the auxiliary blocks 19. By increasing the coefficient of friction, the rubber blocks 20 can more firmly clamp the drill bit 21. When the pneumatic cylinder 15 is activated, the follower plate 16 moves down, and the driven plate 17 pulls the slide plate 18 to move the auxiliary blocks 19 towards the center. The rubber blocks 20 can then clamp the drill bit 21. Conversely, the drill bit 21 is released. This design can avoid the decline in processing quality or machine stoppage caused by drill bit wear or non-compliance with specifications, reduce equipment downtime, and improve overall production efficiency.

[0026] like Figure 1 and Figure 2 The inner wall of the housing 1 is fixedly connected to two fixing rods 8. The outer side of each fixing rod 8 is rotatably connected to the inner wall of the clamping block 6. The clamping block 6 can rotate around the fixing rods 8. At the same time, the outer side of the clamping block 6 is fixedly connected to a docking block 7. The docking block 7 is used to cooperate with the rotating plate 5 to transmit the driving force of the pneumatic cylinder 3 to the clamping block 6 to realize the clamping action. The fixing rods 8 restrict the rotation of the clamping block 6, which can ensure that the clamping block 6 maintains a stable clamping angle when moving and improves the clamping accuracy.

[0027] The external sliding connection of the clamping block 6 is to the inner wall of the tabletop 9. The tabletop 9 provides guidance for the horizontal movement of the clamping block 6, ensuring that the clamping block 6 moves in a straight line during the clamping process and avoids deviation. The external sliding connection of the connecting plate 4 is to the inner wall of the tabletop 9. The tabletop 9 also provides guidance for the vertical movement of the connecting plate 4, ensuring that the driving force of the pneumatic cylinder 3 is accurately transmitted to the rotating plate 5. The sliding cooperation between the two can make the movement of the clamping structure more stable and further improve the reliability of workpiece fixation.

[0028] Two auxiliary rods 13 are fixedly connected to the bottom of the connecting block 11. The auxiliary rods 13 can enhance the stability of the connecting block 11 when sliding on the fixed base 10 and prevent the connecting block 11 from shifting due to vibration caused by the rotation of the motor 12. The external of the housing 1 is fixedly connected to the control console 22. The control console 22 is used to integrate the electrical control system of the equipment. The operator can set the action parameters of the pneumatic cylinder 11 and pneumatic cylinder 215 and the speed of the motor 12 through the control console 22 to realize the automated control of the equipment.

[0029] The follower plate 16 is externally slidably connected to the inner wall of the protective cover 14. The protective cover 14 provides guidance for the up-and-down movement of the follower plate 16, ensuring that the driving force of the pneumatic cylinder 15 is accurately transmitted to the driven plate 17. The auxiliary block 19 is externally slidably connected to the outside of the protective cover 14. The protective cover 14 provides guidance for the horizontal movement of the auxiliary block 19, ensuring that the clamping action of the rubber block 20 on the drill bit 21 is accurately executed. The sliding cooperation between the two can make the action of replacing components more stable and improve the efficiency and reliability of drill bit replacement.

[0030] Working principle: When drilling, the pneumatic cylinder 3 is activated to drive the connecting plate 4 to move the rotating plate 5, which in turn moves the two clamping blocks 6. The fixed rod 8 connected at the bottom restricts one end of the clamping block 6, which makes it easier to bring the clamping block 6 closer to clamp and fix the car door hinge. This makes it easier to fix multiple car door hinges manually, increases safety, and avoids problems such as hole position displacement, hole diameter error or tilting caused by workpiece shaking during drilling. It ensures that the drilling position, depth and angle of each hinge strictly meet the design standards.

[0031] Drilling holes in different sizes of car door hinges requires replacing the entire fixed base 10, which is too cumbersome. At this time, the pneumatic cylinder 15 is activated, which moves the follower plate 16, causing the driven plate 17 to pull the slide plate 18 and move the auxiliary block 19 to facilitate the fixing of the drill bit 21. The rubber block 20 increases friction and better fixes the drill bit 21. This allows the equipment to quickly adapt to various processing needs, eliminating the need for special drilling equipment for each hinge model. This improves the equipment's versatility and processing flexibility, avoids processing quality degradation or processing stagnation caused by drill bit problems, thereby reducing equipment downtime and improving overall production efficiency.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and any equivalent changes made in accordance with the claims of this application are still within the scope of this application.
