Description
Technical Field
[0001] This invention relates to the field of metalworking machine tool technology, and in particular to a drilling machine, which belongs to the field of drilling machine tools and is used for drilling metal fasteners. Background Technology
[0002] In the field of metal cutting, drilling machines are widely used hole-making equipment. Especially in the mass production of metal fasteners (such as bolts, nuts, washers, etc.), the accuracy and efficiency of the drilling process directly affect product quality and production costs. Traditional drilling machines have fixed single-sided worktables. After processing a batch of workpieces, a large amount of metal chips will accumulate on the table, requiring the machine to be stopped for manual or mechanical cleaning, which seriously disrupts the continuous production cycle.
[0003] In existing technologies, such as CN220992824U, a chip removal device for a drilling machine is disclosed. A rectangular groove is opened in the middle of the worktable, and a scraper driven by an electric actuator removes chips. However, this solution has obvious shortcomings: First, the worktable is fixed on one side, which cannot achieve parallel operation of drilling and cleaning; Second, there are dead corners in the scraper cleaning, and small chips are easily stuck in the gaps of the workpiece placement groove, affecting the subsequent workpiece positioning accuracy; Third, its cleaning mechanism requires an independent electric actuator, which increases equipment cost and failure points; Fourth, it does not have the functions of worktable flipping and station rotation, which cannot meet the needs of continuous and efficient production; In addition, when drilling, the worktable of a traditional drilling machine is prone to shaking due to the drilling force, which affects the hole diameter accuracy and position accuracy, and the existing clamping mechanism often requires two sets of power components for workpiece clamping and table locking, which are complex in structure and high in cost. Summary of the Invention
[0004] To address the aforementioned problems, this invention proposes a drilling machine mechanism for metal fastener processing, which more accurately solves the problems described above.

The drilling mechanism includes a main mounting frame, a drilling module, and a positioning module. The drilling module is mounted on the main mounting frame and has a vertical telescopic feed function. A drill bit is mounted at its lower end for drilling and shaping the workpiece in the placement slot on the upward side of the double-sided platform. The positioning module is fixedly mounted on one side of the main mounting frame and includes a single telescopic cylinder and a clamping plate and a support block driven by it. When the telescopic cylinder extends, it drives the clamping plate to press the workpiece, and at the same time drives the support block to insert into the support slot on the back of the double-sided platform to rigidly lock the double-sided platform. When the telescopic cylinder retracts, it releases the workpiece and simultaneously unlocks the double-sided platform, allowing it to flip. The drilling mechanism is also equipped with a transmission module and a chip removal module. The transmission module connects the drilling module and the chip removal module. The chip removal module is an integrated component of this drilling machine and has no independent drive power source. It uses the vertical stroke power of the drilling module's drilling feed. When the drilling module performs the drilling feed action, the vertical feed motion is converted into the horizontal reciprocating cleaning motion of the chip removal module via the transmission module. The double-sided table end face, which is flipped to face down, is cleaned by a combination of brush scraping and high-pressure airflow blowing. The cleaning action is performed synchronously with the drilling process. The chip removal module cannot be used independently without the drilling machine.

[0010] Preferably, the transmission module includes a transverse guide rail and a slide groove. The transverse guide rail is fixedly connected to the upper back of the chassis and communicates with the interior of the chassis. The slots on both sides of the transverse guide rail are inclined downwards to prevent cutting chips from entering the transverse guide rail. The slide groove is located on one side of the mounting frame. A side movable plate is slidably connected inside the mounting frame. A connecting top arm is fixedly connected to the top of the side movable plate. The connecting top arm is fixedly connected to one side of the mounting base.

[0011] Preferably, the debris removal module includes a built-in slider, which is slidably connected to the inner side of the transverse guide rail. The back of the built-in slider is connected to the outer end of the connecting plate. A mounting rail is fixedly connected to the side of the built-in slider inside the chassis.

[0012] Preferably, the positioning module includes a mounting back seat, which is fixedly connected to the back of the mounting main frame. A telescopic cylinder is fixedly connected to the bottom of the mounting back seat, and a pressure frame is fixedly connected to the output end of the telescopic cylinder. Clamping pressure plates are fixedly connected to both sides of the bottom front end of the pressure frame. The clamping pressure plates are located above the placement slot.

[0013] As a preferred option, reserved spaces are provided on both sides of the chassis. When not cleaning, the debris removal module is located in the reserved spaces to avoid affecting the rotation of the double-sided stage.
[0014] The present invention also provides a method for drilling metal fasteners, using the above-mentioned drilling machine, comprising the following steps: S1. Place the metal fastener workpiece in the placement slot on the upper side of the double-sided platform; S2. Start the telescopic cylinder of the positioning module to drive the clamping plate to press the workpiece, and at the same time drive the support block to insert into the support groove to rigidly lock the double-sided platform. S3. Start the drilling module, and the telescopic electric cylinder drives the drill bit to feed downward to perform drilling and shaping of metal fasteners; during the drilling feed, the vertical feed motion is converted into the horizontal reciprocating cleaning motion of the chip removal module through the transmission module, and the double-sided platform end face flipped to face down is cleaned by a combination of brush scraping and high-pressure airflow blowing; cleaning and drilling are carried out simultaneously. S4. After drilling is completed, the telescopic electric cylinder lifts up and resets. The lifting stroke is also driven by the transmission module to drive the chip removal module to complete another round of cleaning. S5. The telescopic cylinder retracts, the clamping plate releases the workpiece, and at the same time the support block exits the support groove, unlocking the double-sided platform. S6. Drive the double-sided platform to rotate 180° to complete the workstation rotation. The cleaned end face is switched to the upper drilling workstation, and the end face with debris is switched to the lower cleaning workstation. Return to step S1 to enter the next drilling and cleaning cycle.
[0015] The present invention has the following advantages: 1. It adopts a double-sided flip-type platform to realize the alternation of drilling and cleaning stations. Drilling and cleaning can be carried out in parallel without stopping the machine for cleaning, which significantly improves the production efficiency of continuous drilling. At the same time, the double-sided platform has placement slots on both sides, and the station can be switched in a single flip. The structure is compact and the operation is reliable.
[0016] 2. The positioning module adopts a single telescopic cylinder, which simultaneously achieves workpiece clamping and rigid locking of the platform through a linkage mechanism. The dual action of one cylinder simplifies the drive system and reduces costs. During the drilling process, the support block is inserted into the support groove to support and reinforce the platform, effectively suppressing the shaking caused by drilling force, greatly improving the drilling dimensional accuracy and position accuracy, and ensuring the processing quality of key hole diameters of metal fasteners.
[0017] 3. The debris removal module fully reuses the drilling feed power of the drilling module, eliminating the need for an independent motor or cylinder drive, which simplifies the overall structure and reduces energy consumption and potential failure points. At the same time, the cleaning action is linked with the drilling feed and lifting reset throughout the entire process. Each drilling operation is accompanied by two cleaning operations: one during feeding and one during lifting, resulting in high cleaning frequency and complete coverage.
[0018] 4. The cleaning method combines brush scraping and high-pressure airflow blowing. The brush can remove large particles of chips attached to the table surface, while the high-pressure airflow three-way nozzle blows away the fine residue in the gaps of the placement slot from multiple angles. The two methods complement each other to ensure the cleanliness of the table surface. Moreover, when cleaning, the table is facing down, and the debris falls into the collection box quickly with the help of gravity, which is not easy to cause secondary pollution.
[0019] 5. The entire cycle of drilling, cleaning, flipping, and re-drilling is fully automated, adapting to the needs of batch continuous production and effectively improving the production efficiency and yield of metal fastener drilling. Attached Figure Description

Detailed Implementation
[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Example 1: Combination Figures 1-9 As shown, this embodiment provides a drilling machine mechanism for processing metal fasteners, including a base 1, a housing 2 on the base 1, a double-sided platform 34 that can be rotated 180° inside the housing 2, and placement slots 35 on the top and bottom surfaces of the double-sided platform 34 for alternately bearing metal fastener workpieces to realize the rotation of drilling positions, and a drilling mechanism 6 is fixedly installed on the top of the housing 2.
[0032] The drilling mechanism 6 includes a mounting frame 61, a drilling module 63, a positioning module 64, a transmission module 65, and a chip removal module 62. The mounting frame 61 is fixedly connected to the chassis 2. The drilling module 63 is mounted on the mounting frame 61 and has a vertical telescopic feed function. A drill bit 636 is mounted at its lower end for drilling and shaping workpieces in the placement slot 35 on the upward side of the double-sided platform 34. The positioning module 64 is fixedly mounted on one side of the mounting frame 61 and includes a single telescopic cylinder 642 and a clamping plate 644 and a support block 647 driven by it. When the telescopic cylinder 642 extends, it drives the clamping plate 644 to press the workpiece, and at the same time drives the support block 647 to insert into the support slot 648 on the back of the double-sided platform 34 to rigidly lock the double-sided platform 34. When the telescopic cylinder 642 retracts, it releases the workpiece and simultaneously unlocks the double-sided platform 34, allowing it to flip.
[0033] The transmission module 65 connects the drilling module 63 and the chip removal module 62. The chip removal module 62 is an integrated component of this drilling machine and has no independent drive power source. It uses the vertical stroke power of the drilling module 63 for drilling feed. When the drilling module 63 performs drilling feed action, the transmission module 65 converts the vertical feed motion into the horizontal reciprocating cleaning motion of the chip removal module 62. It performs a combination of brush scraping and high-pressure airflow cleaning on the flipped-down double-sided table 34 end face. The cleaning action is carried out synchronously with the drilling process. The chip removal module 62 cannot be used independently without the drilling machine.
[0034] By setting up the above structure, during the drilling of metal fasteners, the drilling module 63 can simultaneously drive the chip removal module 62 to enter the working state to clean the lower platform end face by means of the power transmission of the transmission module 65. While the double-sided platform 34 completes the workpiece bearing and station switching inside the machine box 2, the equipment can complete the chip cleaning operation at the corresponding position during the synchronous drilling period. It can make full use of the drilling operation period to complete the cleaning work simultaneously without reserving time for chip cleaning. The drilling mechanism 6 integrates multiple functional modules, so that the drilling, workpiece positioning and chip cleaning can be carried out in coordination, effectively avoiding the accumulation of processing chips and continuously maintaining the cleanliness of the drilling area.
[0035] Combination Figures 1-6As shown, a filter screen box 4 is provided at the bottom of the machine housing 2. The filter screen box 4 is used to filter metal cutting drilling debris. A drain hole 5 is provided on one side of the bottom back of the machine housing 2. The drain hole 5 is used to discharge the filtered cutting fluid. A sealing cover is provided on the outside of the filter screen box 4, and a groove is opened on the outside of the sealing cover. The flip-up platform 3 includes a rotating shaft 31 and a gearbox 32. The gearbox 32 is fixedly connected to the upper side of one side of the machine housing 2. The rotating shaft 31 is rotatably connected to the middle of the top inside the machine housing 2. A first motor 33 is fixedly connected to the outside of the gearbox 32. The output end of the first motor 33 is connected to one end of the rotating shaft 31 through the gearbox 32. A double-sided platform 34 is fixedly connected to the outer surface of the rotating shaft 31. Placement slots 35 are opened on both the top and bottom sides of the double-sided platform 34. The placement slots 35 are used to place the metal fasteners to be drilled.
[0036] A cutting fluid guiding module 7 is fixedly connected to the upper side of one side of the chassis 2. The cutting fluid guiding module 7 includes a side seat 71, which is fixedly connected to the rear end of the top side of the chassis 2. A cutting fluid supply main pipe 72 is fixedly connected to the outer end of the side seat 71. A bent input pipe 73 is fixedly connected to the outer end of the cutting fluid supply main pipe 72. A connecting flange 74 is fixedly connected to the outer end of the bent input pipe 73. A three-way drain pipe 75 is fixedly connected to the outer end of the cutting fluid supply main pipe 72. Both output ends of the three-way drain pipe 75 are fixedly connected to universal bamboo joint cooling pipes 76.
[0037] In the above technical solution, the first motor 33 drives the rotating shaft 31 to rotate via the gearbox 32. The rotating shaft 31 drives the double-sided platform 34 to complete the workstation rotation. The placement slot 35 can hold the metal fasteners to be drilled. Both the upper and lower sides of the double-sided platform 34 can bear the workpiece loading work. The filter screen box 4 placed at the bottom of the machine box 2 receives the metal chips generated by drilling. After the cutting fluid passes through the filter screen box 4 to block solid residues, it can be sent out through the drain hole 5. The cutting fluid guide module 7 is connected to the external liquid supply pipeline by the connecting flange 74. The universal bamboo joint cooling pipe 76 sprays cutting fluid at the workpiece drilling position. During the operation of the equipment, the drilling plane of the double-sided platform 34 can be switched alternately. The cooling liquid is continuously supplied to the drilling point for cooling. The used cutting fluid can be transported out into the circulation pipeline.
[0038] Example 2: Combination Figures 5-8 As shown, the drilling module 63 includes a fixed spindle 631, which is fixedly connected to the top of the mounting frame 61. A mounting top seat 632 is fixedly installed on the top of the fixed spindle 631. A telescopic electric cylinder 633 is fixedly connected to the front end of the mounting top seat 632. A mounting base 634 is fixedly installed at the bottom output end of the telescopic electric cylinder 633. A second motor 635 is fixedly connected to both ends of the mounting base 634. A drill bit 636 is installed at the output end of the second motor 635 by screws.
[0039] The transmission module 65 includes a transverse guide rail 651 and a slide 652. The transverse guide rail 651 is fixedly connected to the upper back of the chassis 2 and communicates with the interior of the chassis 2. The slots on both sides of the transverse guide rail 651 are inclined downwards to prevent cutting chips from entering the transverse guide rail 651. The slide 652 is opened on one side of the mounting frame 61. A side movable plate 653 is slidably connected inside the mounting frame 61. A connecting top arm 654 is fixedly connected to the top of the side movable plate 653. The connecting top arm 654 is fixedly connected to one side of the mounting base 634. A guide component 655 is fixedly connected to the bottom of the side movable plate 653. The rear end of the chip removal module 62 moves within the transverse guide rail 651.
[0040] The guide assembly 655 includes an inclined guide rail 6551, which is fixedly connected to the bottom end of the side movable plate 653. An inclined guide block 6552 is slidably connected inside the inclined guide rail 6551. A connecting shaft 6553 is provided on the side of the inclined guide block 6552 near the chassis 2. A connecting plate 6554 is provided at the outer end of the connecting shaft 6553. The upper end of the connecting plate 6554 is connected to the debris removal module 62. The vertical motion is converted into horizontal motion through the combined constraint of the inclined guide rail 6551 and the horizontal guide rail 651.
[0041] The debris removal module 62 includes a built-in slider 621, which is slidably connected to the inner side of the transverse guide rail 651. The back of the built-in slider 621 is connected to the outer end of the connecting plate 6554. The built-in slider 621 is fixedly connected to a mounting rail 622 on one side inside the chassis 2. A debris cleaning plate 623 is installed inside the mounting rail 622 by screws. The top brush surface of the debris cleaning plate 623 is in contact with the bottom surface of the double-sided platform 34. A pneumatic cleaning assembly 624 is provided on one side of the mounting rail 622.
[0042] The pneumatic cleaning unit 624 includes a side exhaust pipe 6241, which is fixedly connected to one side of the mounting rail 622. A high-pressure airflow hose 6242 is fixedly connected to the input end of the side exhaust pipe 6241. A high-pressure air pump connector 6243 is fixedly connected to the input end of the high-pressure airflow hose 6242 through the rear side of the housing 2. High-pressure airflow three-way nozzles 6244 are fixedly connected to the side of the side exhaust pipe 6241 away from the mounting rail 622 in a linear arrangement at equal intervals. The high-pressure airflow three-way nozzles 6244 are Y-shaped in general, and their output ends are set towards the bottom surface of the double-sided platform 34.
[0043] In the above technical solution, the telescopic electric cylinder 633 drives the mounting base 634 to stably complete the lifting stroke. The mounting base 634 is equipped with a second motor 635 and a drill bit 636 to complete the workpiece drilling operation. During the movement of the mounting base 634, the side movable plate 653 is driven to slide vertically along the slide groove 652 through the connecting top arm 654. The guide component 655 at the bottom of the side movable plate 653 moves synchronously with the displacement. The inclined guide structure formed by the inclined guide rail 6551 and the inclined guide block 6552 is continuously transmitted through the connecting plate 6554, thereby driving the built-in slider 62. 1. The slides laterally inside the transverse guide rail 651. When the built-in slider 621 moves, it drives the mounting frame 622 to fit against the debris cleaning plate 623 to complete the brushing and cleaning operation on the bottom surface of the double-sided platform 34. At the same time, the pneumatic cleaning unit 624 delivers high-pressure airflow to the side drain pipe 6241 through the high-pressure airflow hose 6242. Then, the high-pressure airflow tee nozzle 6244 of the Y-shaped structure sprays airflow toward the surface of the platform to flush and remove the fine debris stuck in the gaps. The entire cleaning action is achieved by the lifting power linkage of the drilling process, without the need for additional power input.
[0044] Example 3: Combination Figures 1-6 and Figure 9 As shown, the positioning module 64 includes a mounting back seat 641, which is fixedly connected to the back of the mounting main frame 61. A telescopic cylinder 642 is fixedly connected to the bottom of the mounting back seat 641. A pressure frame 643 is fixedly connected to the output end of the telescopic cylinder 642. Clamping plates 644 are fixedly connected to both sides of the bottom front end of the pressure frame 643. The clamping plates 644 are located above the placement slot 35. A movable slot 645 is opened inside the mounting back seat 641. A sliding block 646 is slidably connected inside the movable slot 645. A support block 647 is fixedly connected to the front end of the sliding block 646. The back of the platform 34 is provided with a support groove 648. The top of the sliding block 646 is hinged with a linkage rod 649. The top of the linkage rod 649 is hinged to the bottom rear side of the pressure frame 643. When the telescopic cylinder 642 is in the retracted and positioned state, the pressure frame 643 pushes the linkage rod 649 to move the sliding block 646 forward, causing the support block 647 to insert into the support groove 648 to support and reinforce the double-sided platform 34. After the telescopic cylinder 642 extends and unlocks the clamp, the support block 647 and the support groove 648 can be unlocked by pulling the linkage rod 649, and the double-sided platform 34 resumes rotation.
[0045] In the above technical solution, the telescopic cylinder 642 drives the pressure frame 643 to move downward. The pressure frame 643 drives the clamping plate 644 at the bottom to press down, thereby pressing the metal fasteners placed inside the placement slot 35 to ensure the stability of the workpiece position during the drilling process. At the same time as the pressure frame 643 moves downward, it drives the hinged linkage rod 649 to complete the angle change. The linkage rod 649 pulls the sliding block 646 to slide along the movable slot 645 opened in the mounting seat 641. The sliding block 646 drives the front end support block 647 to be inserted into the support slot 648 on the back of the double-sided platform 34. Under the synchronous state of workpiece clamping, the double-sided platform 34 is locked to prevent the platform from shifting position during the drilling process and affecting the drilling accuracy. The entire structure can complete the two operations of workpiece clamping and platform limiting at the same time by relying only on the telescopic cylinder 642 as the power source, reducing the number of independent drive components.
[0046] The chassis 2 has reserved spaces on both sides. When not cleaning, the debris removal module 62 is located in the reserved spaces to avoid affecting the rotation of the double-sided stage 34.
[0047] A method for drilling metal fasteners includes the following steps: S1. The operator places the metal fasteners that need to be drilled one by one into the placement groove 35 opened on the surface of the double-sided platform 34. The initial positioning of the workpiece is completed by relying on the placement groove 35. There is no need for repeated manual alignment. After the workpiece is placed, it can proceed to the subsequent positioning process. S2. The positioning module 64 of the equipment begins to operate. The telescopic cylinder 642 initiates its retraction action. The retraction stroke of the telescopic cylinder 642 causes the pressure frame 643 to move vertically downwards. The continuously moving pressure frame 643 causes the clamping plate 644 mounted at the bottom to move downwards synchronously, so that the clamping plate 644 gradually presses against the surface of the workpiece placed inside the placement slot 35, thereby clamping and positioning the workpiece to prevent it from loosening or shifting during drilling operations and affecting drilling accuracy. During the continuous downward movement of the pressure frame 643, the bottom rear side of the pressure frame 643 forms a hinged linkage rod 649. The squeezing and pushing force causes the linkage rod 649 to rotate and change displacement under the force, which in turn continuously pushes the sliding block 646 to slide smoothly forward inside the movable groove 645 of the mounting seat 641. The sliding block 646 moves forward and drives the support block 647 fixedly installed at its front end to move forward synchronously, so that the support block 647 is fully inserted into the support groove 648 opened on the back of the double-sided platform 34. Through the precise insertion and cooperation between the support block 647 and the support groove 648, the double-sided platform 34 is fully supported and reinforced after the workpiece is positioned, so that the double-sided platform 34 remains stable throughout the drilling process. S3. After the double-sided platform 34 has completed its positioning, locking, and workpiece clamping processes, the drilling module 63 is activated to perform drilling operations. The telescopic electric cylinder 633 mounted at the bottom of the mounting base 632 begins to extend downwards. The extension stroke of the telescopic electric cylinder 633 causes the mounting base 634 to move downwards smoothly. The second motor 635, fixedly mounted at both ends of the mounting base 634, moves downwards synchronously. After being energized, the second motor 635 continues to run at high speed. The output end of the second motor 635 rotates synchronously at high speed through the drill bit 636, which is fastened to it with screws. The high-speed rotating drill bit 636 continuously contacts the workpiece fixed inside the placement slot 35, thereby completing the punching of the metal fastener. In conjunction with the drilling process, the equipment is equipped with two independent sets of drill bits 636. Simultaneously, two sets of placement slots 35 are symmetrically arranged on both sides of the top of the double-sided platform 34. These two sets of structures cooperate with each other, allowing simultaneous drilling of two workpieces in a single drilling stroke. During each complete drilling stroke, as the telescopic electric cylinder 633 extends downwards to perform the drilling, the mounting base 634 moves downwards along with the telescopic electric cylinder 633, causing the side-fixed connecting top arm 654 to move vertically in sync. The connecting top arm 654 is slidably connected to the sliding groove 652 of the mounting frame 61, and its movement directly drives the sliding groove 652. The internally mounted side movable plate 653 slides downward synchronously, and the inclined guide rail 6551 fixed at the bottom of the side movable plate 653 moves downward synchronously. The inclined guide rail 6551 has an inclined arrangement structure. An inclined guide block 6552 is slidably mounted inside the inclined guide rail 6551. The front end of the inclined guide block 6552 is rotatably connected to a connecting plate 6554 through a connecting shaft 6553. The other end of the connecting plate 6554 is fixedly connected to the built-in slider 621 slidably mounted inside the transverse guide rail 651. During the downward movement of the inclined guide rail 6551, the inclined guide block 6552 is simultaneously limited by the inclined track of the inclined guide rail 6551 and the transverse guide rail 6551. 1. The horizontal limit of the built-in slider 621, the inclined guide block 6552 can only slide in a direction along the inclined trajectory of the inclined guide rail 6551. The inclined sliding action of the inclined guide block 6552 continuously pulls the built-in slider 621 through the connecting shaft 6553 and the connecting plate 6554, so that the built-in slider 621 completes the first direction of lateral sliding inside the transverse guide rail 651. During the sliding process of the built-in slider 621, it drives the mounting rail 622 fixed at its front end to move laterally in sync. The debris cleaning plate 623 fixed by screws inside the mounting rail 622 moves laterally in sync, and completes the first round of full-width brush scraping on the bottom surface of the double-sided platform 34 that has been flipped to face down.While the debris sweeping plate 623 is performing mechanical cleaning, the external high-pressure air pump continues to work. The high-pressure airflow generated by the high-pressure air pump is continuously delivered to the side exhaust pipe 6241 inside the machine box 2 through the high-pressure airflow hose 6242. The side exhaust pipe 6241 evenly distributes the high-pressure airflow and then delivers it to the high-pressure airflow three-way nozzles 6244 arranged linearly at equal intervals. The high-pressure airflow three-way nozzles 6244 adopt a Y-shaped structure design. The nozzle output end is tilted in both directions towards the bottom surface of the double-sided platform 34, spraying high-pressure airflow onto the platform surface from multiple tilt angles. The high-pressure airflow directly blows away the fine metal debris stuck in the gaps on the platform surface that the debris sweeping plate 623 cannot brush off. The cleaning and drilling are carried out simultaneously without the need for additional cleaning waiting time. S4. After all drilling operations are completed, the telescopic electric cylinder 633 retracts upwards to reset, causing the mounting base 634, the second motor 635, and the drill bit 636 to rise upwards as a whole, completely detaching the drill bit 636 from the workpiece and ending the drilling process. During the upward stroke of the telescopic electric cylinder 633, the connecting top arm 654 moves vertically upwards in sync, causing the side movable plate 653 and the inclined guide rail 6551 to move upwards in sync. This is achieved through the transmission of the inclined guide block 6552 and the connecting plate 6554. The internal slider 621 slides laterally in the opposite direction within the transverse guide rail 651, driving the debris cleaning plate 623 to complete the second round of full-width scraping, further cleaning the scattered metal debris remaining on the platform surface. The double-sided platform 34 remains face down during the cleaning process. The metal debris separated by mechanical cleaning and high-pressure airflow falls rapidly downwards under its own gravity, all landing on the surface of the filter box 4 mounted at the bottom of the chassis 2. The filter box 4 is independently located at the bottom of the chassis 2, completing... The machine intercepts solid metal debris. After use, the cutting fluid penetrates the filter screen box 4 and is diverted. Finally, it is discharged outward through the drain hole 5 at the bottom of the back of the machine box 2. The drain hole 5 is connected to the cutting fluid circulation system of the drilling machine, allowing the used cutting fluid to be transported to the circulation equipment for purification before being put back into the drilling cooling process, thus realizing the recycling of cutting fluid. The filter screen box 4 adopts a drawer-type assembly structure. The operator removes the sealing cover by prying open the groove on the outside of the sealing cover and pulls out the filter screen box 4 directly to clean the metal debris accumulated during the drilling operation of the metal cutting drilling machine. During the drilling process, the operator connects to the external cutting fluid supply pipeline through the connecting flange 74. The cutting fluid is introduced into the cutting fluid supply main pipe 72 through the bent input pipe 73, and then diverted to the two universal bamboo joint cooling pipes 76 through the three-way drain pipe 75. The operator can freely adjust the spray angle of the universal bamboo joint cooling pipes 76 to ensure that the cutting fluid is accurately sprayed on the drilling points of the two sets of placement slots 35, continuously cooling the drilling area. S5. Telescopic cylinder 642 switches to the extended state. The extended telescopic cylinder 642 drives the pressure frame 643 to rise vertically upward. The clamping pressure plate 644 then detaches from the workpiece surface, releasing the clamping and positioning of the metal fastener. At the same time, the upward-moving pressure frame 643 pulls the linkage rod 649 in the opposite direction. After the linkage rod 649 rotates in the opposite direction, it pulls the sliding block 646 to slide backward inside the movable groove 645. The sliding block 646 drives the support block 647 to be completely pulled out from inside the support groove 648, completely releasing the support and locking of the double-sided platform 34. This will not hinder the rotating shaft 31 from driving the double-sided platform 34 to complete the flipping operation. S6. Start the first motor 33. The output power of the first motor 33 is transmitted to the rotating shaft 31 through the internal gear structure of the gearbox 32. During the continuous rotation of the rotating shaft 31, the double-sided platform 34 is rotated 180 degrees. The platform end face that was originally facing upwards after drilling and has a lot of metal debris attached is rotated to the downward position inside the machine housing 2. The platform end face that was originally facing downwards and kept clean is rotated to the upper drilling station, completing the station rotation. The clean end face is switched to the upper drilling station, and the end face with debris is switched to the lower cleaning station. Return to step S1 to start the next round of drilling and cleaning cycle. The whole device relies on the bidirectional drilling stroke of the telescopic electric cylinder 633 to connect... The drive module 65 and the debris removal module 62 operate synchronously. The drilling downward stroke and the telescopic electric cylinder 633 upward reset stroke can both drive the bottom cleaning work of the double-sided platform 34, increasing the cleaning coverage and cleaning frequency. There is no need to stop the machine to remove debris. The double-sided platform 34 switches between the upper and lower working positions by flipping. The clean end face that has been cleaned is placed upward for drilling, while the end face with debris is placed downward to receive dual cleaning from the debris cleaning plate 623 and the high-pressure airflow three-way nozzle 6244. The drilling and debris removal processes are completed alternately in a cycle. All components operate in coordination, and the drilling and cleaning processes run synchronously without interfering with each other, which can effectively improve the drilling efficiency.
