Description

Technical Field

[0001] This invention relates to the field of door and window drilling technology, and more specifically, to a horizontal double-headed hinge drilling machine for aluminum alloy doors and windows. Background Technology

[0002] To ensure the normal use and functionality of aluminum alloy doors and windows, drilling is often performed on the door and window profiles during the production process. This allows for the installation of hardware accessories such as handles, locks, hinges, and other fittings. In addition to installing hinges, holes are also needed to allow for the splicing and assembly of the profiles, ensuring the structural integrity and stable performance of the aluminum alloy doors and windows.

[0003] Research revealed that when hinge drill bits are used to drill holes in aluminum alloy doors and windows, the impact force generated by the drill bit can easily cause the aluminum alloy doors and windows to vibrate. Especially considering that the door and window area may be large, if the fixing range is limited when clamping and fixing them on both sides, it is very likely to affect the fixing effect during drilling, which may lead to deviations in the drilling position. In severe cases, it may even cause the door and window to be scrapped, resulting in material waste and increased costs. In addition, during the drilling process, the high-speed rotation of the drill bit cutting the aluminum alloy material produces chips with high speed and kinetic energy, causing the chips to fly in all directions. This not only pollutes the working environment, but may also scratch operators or damage surrounding equipment, posing a significant safety hazard. Furthermore, some chips may remain in the drilled holes, inner grooves, and other parts of the aluminum alloy doors and windows, which are difficult to remove. This not only affects the appearance of the doors and windows, but also affects the smoothness of opening and closing, increasing noise and jamming during use.

[0017] Preferably, the air inlet of the suction fan is provided with a dustproof net, and a soft brush is provided on one side of the cleaning plate facing the dustproof net.

[0018] Preferably, the positioning cylinder and the partition plate are provided with movable grooves that match the rotation trajectory of the mounting key, the lower end of the air guide tube extends to the lower side of the suction fan, the arrangement of the air guide tube and the drill rod is parallel to the placement direction of the door and window frame to be drilled, the side wall of the mounting shell is hinged with an isolation door, the end of the isolation door is provided with a magnetic suction part, and the magnetic suction part is magnetically attached to the outer side wall of the mounting shell.

[0019] The beneficial effects of this invention are:

[0020] 1. This invention utilizes the rotation of the drill rod to drive a suction fan, synchronizing the dust extraction and blowing components with the drilling action. No additional power source is required, improving energy efficiency. With the addition of a dust-proof cartridge, the suction fan effectively collects most of the chips and dust generated during drilling. The chips and dust are drawn into the chip storage chamber through the chip inlet, maintaining a clean working environment. The resulting suction drives airflow, carrying away heat and adhering chips generated by the drill rod and drilling area, thus helping to improve the lifespan of the drill rod and the drilling quality.

[0021] 2. After being filtered by the dust filter, the airflow is discharged through the air duct. This airflow is parallel to the direction of the door and window frame to be drilled, which can clean the previously drilled hinge holes and ensure the smooth progress of subsequent processing operations such as hinge installation. This solves the problem of residue affecting aesthetics and performance, and improves processing quality. Moreover, during drilling, the dust filter tube abuts against the upper side wall of the door and window frame before the drill rod. The downward movement of the mounting shell causes the soft brush to abut against the side wall of the dust filter to clean the dust adhering to the dust filter, prevent the dust filter from clogging, ensure the stability of the suction power of the fan, and thus continuously and effectively carry out dust collection.

[0022] 3. The door and window frame is fixed on four sides using clamping parts, baffles, adjusting plates, and support bases. Combined with the pre-contact fixing of the area to be drilled using a dust-proof tube, and the spring buffering the drilling impact force, the movement freedom of the door and window frame in the horizontal and vertical directions is restricted in multiple dimensions. This effectively resists the impact force of the drill bit, avoids vibration and deformation of the door and window frame, and prevents drilling position deviation, thus reducing the scrap rate of doors and windows. In addition, when chips are generated, most of them will be stored in the dust-proof tube, thereby preventing chips from splashing into the work area and maintaining a clean working environment. In addition to adapting the dust-proof tube to the thickness of the door and window frame, the spring also plays a certain role in buffering and stabilizing the door and window frame. When the drill rod applies drilling force to the door and window frame, the spring can absorb part of the impact force and reduce the vibration of the door and window frame. This buffering effect helps to maintain the stability of the door and window frame, improves the drilling accuracy, and improves the processing quality of the door and window frame.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0036] Example 1, refer to Figures 1-7A horizontal double-head hinge drilling machine for aluminum alloy doors and windows includes an operating table 1 and a door / window frame 10. The operating table 1 is equipped with a positioning mechanism 2, a translation mechanism 3, and a support base 11. The positioning mechanism 2 is used to clamp the door / window frame 10. The translation mechanism 3 is equipped with a lifting mechanism 4, and a motor 5 is mounted on the lifting mechanism 4. A connecting sleeve 51 is fixedly connected to the output end of the motor 5. A drill rod 52 is installed at the lower end of the connecting sleeve 51. The upper end of the drill rod 52 has a threaded portion 521. The lower end of the connecting sleeve 51 has an internal thread matching the threaded portion 521. The machine also includes:

[0037] Dust collection support assembly: The dust collection support assembly surrounds the outside of drill pipe 52;

[0038] Vacuum and blower assembly: The vacuum and blower assembly is located below the motor 5.

[0039] Furthermore, the positioning mechanism 2 includes two translation cylinders 21 and a clamping component 25. The two translation cylinders 21 are centrally symmetrically distributed and are fixedly installed on the operating table 1. The output end of the translation cylinder 21 is connected to a moving base 22, and a lifting cylinder 23 is fixedly installed on the moving base 22. The output end of the lifting cylinder 23 is connected to an adjusting cylinder 24, and the output end of the adjusting cylinder 24 is connected to the clamping component 25. The translation cylinder 21 can drive the subsequent components to move horizontally, providing a horizontal adjustment function for the positioning of the door and window frame 10. It can adapt to the placement of door and window frames 10 of different lengths and ensure the accuracy of positioning. The lifting cylinder 23 realizes the vertical position adjustment, so that the clamping component 25 can rise or fall to a suitable height to match door and window frames 10 of different thicknesses. The adjusting cylinder 24 is used to fine-tune the position of the clamping component 25 to adjust the position of the door and window frame 10. Through the setting of the positioning mechanism 2, it can cooperate with the drill rod 52 to realize multi-position drilling.

[0040] A baffle is provided at one end of the clamping member 25 away from the adjusting cylinder 24. An adjusting plate is slidably provided on the clamping member 25. The side walls of the door and window frame 10 abut against the baffle and the adjusting plate respectively. The adjusting plate slidably provided on the clamping member 25, together with the baffle, can tightly abut against the side walls of the door and window frame 10, so as to achieve reliable clamping of the door and window frame 10, ensure the stability of the door and window frame 10 during drilling, and avoid affecting the drilling accuracy due to shaking. When drilling, the door and window frame 10 is placed on the support base 11. At this time, the door and window frame 10 is fixed on all four sides by the clamping member 25, the baffle, the adjusting plate and the support base 11 to ensure the stability during drilling.

[0041] Furthermore, the translation mechanism 3 includes a translation motor 31 and a guide rail, both of which are fixed on the operating table 1. A lead screw 32 is connected to the output end of the translation motor 31. A bearing seat for limiting the lead screw 32 is installed on the operating table 1. Two sets of threaded segments with opposite directions are symmetrically arranged along the central axis of the translation motor 31. Each threaded segment is threadedly connected to a sliding seat 33. The sliding seat 33 includes a lead screw nut 331 and a base 332 fixedly installed on the lead screw nut 331. The lead screw nut 331 is threadedly connected to the threaded segment, and the base 332... A slider is fixedly installed on the lower side, and the slider is slidably connected to the guide rail. When the translation motor 31 is started, the lead screw 32 rotates, which will drive the two sliding seats 33 to move in opposite directions or towards each other, thereby controlling the position of the drill rod 52 to realize the drilling of the hinge holes on both sides. The lifting mechanism 4 includes a mounting frame 41, which is fixedly installed on the base 332. A lifting device 42 is installed on the mounting frame 41. The motor 5 is installed on the lifting slider of the lifting device 42. Through the lifting device 42, the motor 5 and the drill rod 52 can be controlled to move up and down, thereby realizing the drilling operation.

[0042] The dust collection assembly includes a mounting shell 6 and a dust collection cylinder 7. The mounting shell 6 has an internal partition 61 that divides its interior into a chip collection chamber 60 and a mounting chamber 601. A positioning cylinder 62 is fixedly connected to the lower side of the partition 61. The bottom wall of the mounting shell 6 has an annular groove that matches the dust collection cylinder 7, and this groove contains a limiting strip that axially limits the movement of the dust collection cylinder 7, ensuring that it can only move up and down. A positioning ring is located at the upper end of the dust collection cylinder 7. 70. The positioning ring 70 is located inside the chip collection cavity 60. The lower end of the dust-proof cylinder 7 is provided with an installation ring 701. The top wall of the installation ring 701 is elastically connected to the bottom wall of the positioning cylinder 62 by a spring 71, so that the dust-proof cylinder 7 can move up and down within a certain range to adapt to door and window frames 10 of different thicknesses. The upper side wall of the mounting shell 6 is fixedly connected with an installation sleeve 64. The end of the motor 5 is provided with an installation groove that matches the installation sleeve 64. The mounting shell 6 can be fixed to the lower side of the motor 5 by the installation sleeve 64 and bolts.

[0043] It should be noted that the lower port of the dust collector 7 is tapered from top to bottom, which helps to create a local negative pressure area during drilling, making it easier for chips to be sucked into the chip collection chamber 60, thus improving the dust collection effect. The lower side wall of the connecting sleeve 51 abuts against the top wall of the mounting shell 6. The mounting shell 6 and the mounting cavity 601 are provided with through holes that match the drill rod 52. The drill rod 52 passes through the inside of the mounting shell 6 and extends into the dust collector 7. When the spring 71 is in its initial state, the lower end of the drill rod 52 is above the mounting ring 701. When the drill rod 52 descends to drill, the dust collector 7 will contact the door and window frame 10 before the drill rod 52. On the one hand, it can fix the area of ​​the door and window frame 10 to be drilled during drilling to prevent it from shaking and affecting the drilling accuracy. On the other hand, it can prevent chips from splashing during drilling, so that most of the chips can be collected in the dust collector 7 for easy collection.

[0044] In this embodiment, the translation cylinder 21 is activated, driving the moving seat 22 to move horizontally, providing horizontal position adjustment for the positioning of the door and window frame 10, which can adapt to the placement of door and window frames 10 of different lengths. The door and window frame 10 is fixed in the center on the clamping member 25 by the adjusting plate and the baffle. The lifting cylinder 23 is activated, causing the clamping member 25 to rise or fall to adapt to door and window frames 10 of different thicknesses. The adjusting cylinder 24 makes fine adjustments to the clamping member 25 to achieve drilling in the same row. The positioning mechanism 2, through the cooperation of the translation cylinder 21, the lifting cylinder 23 and the adjusting cylinder 24, can accurately position door and window frames 10 of different lengths and thicknesses, ensuring the accuracy and stability of drilling, and avoiding the impact of drilling quality due to inaccurate positioning of the door and window frame 10.

[0045] When the translation motor 31 starts, it drives the lead screw 32 to rotate. Since the lead screw 32 has two sets of threaded segments with opposite directions of rotation symmetrically arranged along the central axis, the sliding seat 33, which is threadedly connected to the threaded segments, will move in opposite directions according to the direction of rotation of the threads. The lead screw nut 331 cooperates with the threaded segments, and the slider on the lower side of the base 332 slides on the guide rail, realizing the smooth movement of the sliding seat 33, thereby controlling the position of the drill rod 52 installed on the lifting mechanism 4, so as to realize the drilling of the hinge holes on both sides of the aluminum alloy door and window.

[0046] When drilling holes in the door and window frame 10, the lifting device 42 controls the motor 5 and the drill rod 52 to descend, so that the drill rod 52 contacts the door and window frame 10 and drills holes. After drilling is completed, the lifting device 42 raises the motor 5 and the drill rod 52 to perform the next drilling.

[0047] Before drilling, the door and window frame 10 is fixed on four sides by the clamping component 25, the baffle, the adjusting plate, and the support base 11. The translation cylinder 21 drives the moving base 22 to move, the lifting cylinder 23 adjusts the height, the adjusting cylinder 24 makes fine adjustments, and the adjusting plate slides on the clamping component 25. It can be adjusted according to the specific size of the door and window frame 10 to ensure tight contact. The support base 11 provides bottom support for the door and window frame 10. This four-sided fixing method constrains the door and window frame 10 from multiple directions, limiting the degree of freedom of movement of the door and window frame 10 in the horizontal and vertical directions. Since the drill rod 52 will apply a certain force to the door and window frame 10 during the drilling process, if the door and window frame 10 is not fixed firmly, it is easy to shake, affecting the drilling accuracy and even causing the drilling position deviation. By fixing on four sides, the door and window frame 10 forms a stable whole, which can withstand the force during drilling, ensuring the stability and accuracy of drilling and meeting the requirements of door and window assembly.

[0048] During drilling, the dust-proof cylinder 7 first contacts the door / window frame 10 to fix the area of ​​the door / window frame 10 to be drilled. This pre-contact method of the dust-proof cylinder 7 further stabilizes the area of ​​the door / window frame 10 to be drilled before the drill rod 52 drills. Because the contact area between the dust-proof cylinder 7 and the door / window frame 10 is relatively large, it can apply pressure evenly and prevent the door / window frame 10 from undergoing local deformation or shaking during drilling. For example, when drilling thin aluminum alloy door / window frames 10, the fixing effect of the dust-proof cylinder 7 can prevent the door / window frame 10 from shifting at the moment of drilling, ensuring the drilling quality. In addition, when chips are generated, most of the chips will be stored in the dust-proof cylinder 7, thereby preventing chips from splashing into the work area and keeping the working environment clean. At the same time, this function of preventing chips from splashing also helps to protect the safety of operators and reduce the injury of operators to chips.

[0049] During drilling, since different door and window frames 10 may have different thicknesses, the elastic deformation capability of the spring 71 allows the dust-proof cylinder 7 to automatically adjust its position according to the thickness of the door and window frame 10, ensuring that the dust-proof cylinder 7 can make close contact with the door and window frame 10, thus achieving adaptability to door and window frames 10 with different thicknesses. For example, for door and window frames 10 with large thickness differences, the spring 71 can ensure that the dust-proof cylinder 7 always plays a role in fixing and collecting dust. In addition to adapting the dust-proof cylinder 7 to the thickness of the door and window frame 10, the spring 71 also plays a certain role in buffering and stabilizing the door and window frame 10. When the drill rod 52 applies drilling force to the door and window frame 10, the spring 71 can absorb part of the impact force and reduce the vibration of the door and window frame 10. This buffering effect helps to maintain the stability of the door and window frame 10, improve the drilling accuracy and the processing quality of the door and window frame 10. For example, when drilling a larger diameter hole, the drilling force is larger, and the buffering effect of the spring 71 can effectively reduce the vibration amplitude of the door and window frame 10, ensuring the drilling effect.

[0050] Example 2, refer to Figures 5-10The dust extraction and blowing assembly includes a first gear 8 and a second gear 81 installed in the mounting cavity 601, and a suction fan 9 installed in the chip collection cavity 60. The first gear 8 has a keyway 80 inside, and a mounting key 522 is provided on the drill rod 52 corresponding to the keyway 80. The keyway 80 inside the first gear 8 cooperates with the mounting key 522 on the drill rod 52, allowing the first gear 8 to rotate synchronously with the drill rod 52. A limiting part 801 is fixedly connected to the lower side of the first gear 8. The partition 61 has a limiting groove 802 inside that matches the limiting part 801. The first gear 8 is rotatably engaged with the partition 61 through the limiting part 801. The suction fan 9 has blades 91 inside, and the first gear 8 and the second gear 81 mesh with each other. When gear 8 rotates, it drives gear 2 81 to rotate through meshing. Gear 2 81 is internally fixedly connected to a connecting shaft 811. A washer 82 is provided between the lower side of gear 2 81 and the partition 61 to prevent gear 2 81 from directly contacting the partition 61 and causing wear. The lower end of the connecting shaft 811 passes through the washer 82 and the partition 61 and is connected to the blade 91. Gear 2 81 transmits power to the blade 91 through the connecting shaft 811, thereby generating suction. The suction fan 9 is fixed to the lower side of the partition 61 by the mounting bolt 94. The rotation of the drill rod 52 is used to drive the suction fan 9, which does not require an additional power source, saves energy, and makes the dust collection and blowing assembly synchronized with the drilling action.

[0051] Furthermore, the dust extraction and blowing assembly also includes a cleaning plate 72, a chip inlet 621 on the side wall of the positioning cylinder 62, and an air guide duct 92 that is connected through the lower side wall of the suction fan 9. The air guide duct 92 is the air outlet of the suction fan 9, and the air inlet of the suction fan 9 is set facing the chip inlet 621. The cleaning plate 72 is fixed to the positioning ring 70 by the positioning bolt 721. During the drilling process, the blades 91 inside the suction fan 9 rotate, causing the suction fan 9 to generate suction. On the one hand, the generated chips and dust are sucked into the chip storage chamber 60 through the chip inlet 621 under the suction of the suction fan 9. On the other hand, it can also clean the chips adhering to the drill rod 52, and at the same time, it can also cool the drill rod 52 and the drilling area.

[0052] The positioning cylinder 62 and the partition plate 61 are provided with movable grooves that match the rotation trajectory of the mounting key 522, thus avoiding motion interference. During installation, the mounting shell 6 is installed first, and then the drill rod 52 is installed. After aligning the mounting key 522 of the drill rod 52 with the keyway 80 of the gear 8, it is inserted upward and rotated, thus connecting it to the connecting sleeve 51 by thread. The lower end of the air guide tube 92 extends to the lower side of the suction fan 9. The arrangement of the air guide tube 92 and the drill rod 52 is parallel to the placement direction of the door and window frame 10 to be drilled, which facilitates automatic cleaning of the previously drilled holes. The side wall of the mounting shell 6 is hinged with an isolation door 63. The end of the isolation door 63 is provided with a magnetic suction part 631, which magnetically adheres to the outer side wall of the mounting shell 6. The isolation door 63 can close the chip collection chamber 60 when not in operation to prevent dust and debris from entering, while being easy to open when maintaining and cleaning the chip collection chamber 60.

[0053] It should be noted that the air inlet of the suction fan 9 is equipped with a dustproof net 93. The dustproof net 93 ensures that the chips are trapped inside the chip storage chamber 60, and the filtered air is discharged downward from the air guide duct 92. The downward air can clean the previously drilled hinge holes, and the chips and dust remaining in the door and window frame 10 will also be blown away from the processing area by this air. A soft brush is provided on the side of the cleaning plate 72 facing the dustproof net 93. When drilling, the cleaning plate 72 can completely cover the dustproof net 93 and the end of the soft brush abuts against the side wall of the dustproof net 93. When drilling, the dustproof cylinder 7 abuts against the upper side wall of the door and window frame 10. At this time, the mounting shell 6 continues to move downward. During this process, the soft brush can clean the dust attached to the dustproof net 93, prevent the dustproof net 93 from being blocked, and ensure that the suction power of the suction fan 9 is stable and can continuously and effectively perform dust collection.

[0054] In this embodiment, during installation, the mounting shell 6 is installed first, and then the mounting key 522 of the drill rod 52 is aligned with the keyway 80 of the gear 8 and inserted upward and rotated to achieve a threaded connection between the drill rod 52 and the connecting sleeve 51. This installation method ensures accurate connection between the components, enabling the dust extraction and blowing assembly to operate normally. When the drill rod 52 is damaged, it can be directly replaced without disassembling the mounting shell 6, which is quite convenient.

[0055] Motor 5 transmits power to drill rod 52. The keyway 80 of gear 1 8 engages with the mounting key 522 of drill rod 52, allowing gear 1 8 to rotate synchronously with the rotation of drill rod 52. The meshing connection between gear 1 8 and gear 2 81 allows gear 1 8 to rotate via gear transmission, and gear 2 81 drives blade 91 to rotate via connecting shaft 811, thereby generating suction force in the suction fan 9. The air inlet of the suction fan 9 faces the chip inlet 621 opened on the side wall of the positioning cylinder 62. During drilling, most of the chips remain inside the dust separator 7. The chips and dust generated by the rotation of drill rod 52 are drawn away by the suction force generated by the rotation of blade 91 inside the suction fan 9. The chips 621 are sucked into the chip collection chamber 60. This dust collection method can effectively collect the chips and dust generated during drilling, keeping the working environment clean. The rotation of the drill rod 52 drives the suction fan 9, realizing the synchronization of the dust collection and blowing components with the drilling action. No additional power source is required, which improves energy utilization efficiency. The suction force generated can not only collect chips and dust, but also clean the chips adhering to the drill rod 52. At the same time, it cools the drill rod 52 and the drilling area. This is because the suction force generated by the suction fan 9 can drive the air flow. The air flow can carry away the heat generated by the drill rod 52 and the drilling area, playing a cooling role and helping to improve the service life of the drill rod 52 and the drilling quality.

[0056] The dust filter 93 installed at the air inlet of the suction fan 9 can effectively intercept chips, ensuring that the chips are trapped inside the chip storage chamber 60. The filtered air is discharged downward from the air guide 92. Since the air guide 92 and the drill rod 52 are arranged parallel to the placement direction of the door and window frame 10 to be drilled, the air can directly act on the previously drilled hole. This directional air can blow away the chips and dust remaining in the door and window frame 10 from the processing area, further improving the dust collection effect and processing quality. Specifically, the air can blow out the chips and dust in the hole, preventing them from accumulating in the hole and affecting subsequent processing operations, such as hinge installation.

[0057] During drilling, the dust collector 7 abuts against the upper side wall of the door and window frame 10, and the mounting shell 6 continues to move downward, so that the soft brush abuts against the side wall of the dustproof net 93. The soft brush can clean the dust attached to the dustproof net 93, prevent the dustproof net 93 from clogging, and ensure the suction power of the suction fan 9 is stable, so as to continuously and effectively carry out the dust collection work.

[0058] It should be noted that the specific model and specifications of the motor and cylinder need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
