Description

TECHNICAL FIELD

[0001] The application relates to the technical field of aluminum alloy door and window processing equipment, in particular to an aluminum alloy door and window production positioning and drilling device. BACKGROUND

[0002] Aluminum alloy doors and windows have become the mainstream choice of modern building doors and windows due to the core advantages of high strength, excellent sealing performance and beautiful appearance. Among them, three-dimensional arc aluminum alloy doors and windows (such as arc windows and arched doors) have unique value in improving the aesthetic quality of buildings and the level of space design due to their smooth streamline shape, and are widely used in high-end building scenes such as large curtain walls, daylighting roofs and revolving doors.

[0003] The existing three-dimensional arc aluminum alloy door and window outer frame is usually composed of two arc-shaped frame strips and two straight frame strips through the butt joint of the forty-five-degree chamfered corners at the end. The assembly core is to use the fastening mode of pre-buried corner codes. This process requires that a positionally accurate through hole be processed on the outer side wall of the butt joint end of the arc-shaped frame and the straight frame to ensure that the fastening screw can pass through the holes on the side walls of the two profiles in turn and be accurately screwed into the threaded hole of the corner code, forming a high-strength corner connection.

[0004] However, in actual processing, due to the constraints of the arc-shaped frame shape, the drilling process of the arc-shaped frame and the straight frame strip can only be carried out separately. This step-by-step processing method lacks a unified clamping reference and reliable positioning constraint, and can only rely on manual positioning and the accuracy of the machine tool, which can easily cause the pre-drilled holes on the side walls of the arc-shaped frame and the straight frame to have uncontrollable axial deviation (i.e., the holes do not coincide in the axial direction of the screw). This error can cause the screw to be difficult or even impossible to screw into the corner code during final assembly, thereby significantly reducing the corner connection strength of the door and window, introducing the risk of structural looseness, and seriously affecting the overall stability, sealing performance and service life of the product.

[0005] Therefore, the application provides an aluminum alloy door and window production positioning and drilling device to solve the above problems. SUMMARY

[0039] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present application shall fall within the protection scope of the present application.

[0040] The aluminum alloy door and window production positioning and drilling device provided by the embodiments of the present application solves the problem of relative deviation of hole positions caused by lack of a unified reference in step-by-step processing of diagonal connection of an existing three-dimensional arc aluminum alloy door and window outer frame, and the problem of insufficient corner connection strength and reduced sealing performance. In use, through the cooperation of the profile roller conveying assembly, the profile laying assembly, the push and clamping assembly, and the execution assembly, precise butt joint and one-time coaxial through drilling of the arc frame and the straight frame are achieved, axial hole position deviation is eliminated, the corner connection strength and sealing performance of the door and window are significantly improved, and the product quality and service life are ensured.

[0041] The technical solutions in the embodiments of the present application are as follows to solve the above technical problems.

[0042] Embodiment one, please refer to Figures 1-13 The aluminum alloy door and window production positioning and drilling device provided by the embodiments of the present application includes a workbench 1, an extension table 2 installed on one side of the workbench 1, and a drilling device 3 for drilling processing of door and window profiles on the extension table 2. An adjusting assembly 4 for adjusting the drilling angle of the drilling device 3 is further arranged on the extension table 2. A profile roller conveying assembly 5 for conveying and positioning an arc frame strip is arranged on the workbench 1. A profile laying assembly 6 for laying and pre-positioning a straight frame strip is arranged in the middle of the workbench 1. A push and clamping assembly 7 is arranged in the workbench 1. The push and clamping assembly 7 includes a middle frame groove 71 arranged in the middle of the workbench 1, and a rotatable torsion spring lever plate 72 and a liftable clamping table 73 arranged in the middle frame groove 71 in sequence. When the profile roller conveying assembly 5 rotates the butt joint angle of the arc frame strip to the processing area, the torsion spring lever plate 72 is first triggered to push the straight frame strip to complete the butt joint of the inclined surface, and then the clamping table 73 is triggered to lift the straight frame strip for impact-resistant clamping. Finally, the coaxial through inclined hole processing on the sidewalls of the arc frame and the straight frame is completed by the drilling device 3 with a preset angle at one time.

[0043] Further, the clamping table 73 is slidingly installed in the middle frame groove 71. Reset spring columns 731 are slidingly installed on the front and rear sides of the clamping table 73, and the reset spring columns 731 are installed on the top wall of the workbench 1. An electric clamping jaw 732 is installed at the top end of the clamping table 73, and the trigger signal of the electric clamping jaw 732 is provided by the lifting action of the clamping table 73.

[0044] The aluminum alloy door and window production positioning drilling device is used for processing a three-dimensional circular arc door and window outer frame composed of two arc-shaped frame strips and two straight frame strips (45-degree chamfered end butt joint), the straight frame strip is pre-positioned through the profile laying assembly 6, the arc-shaped frame strip is transported and positioned through the profile roller conveying assembly 5, the drilling equipment 3 is adjusted to 45 degrees and aligned with the butt joint center through the adjusting assembly 4, the straight frame strip and the arc-shaped frame strip are pushed and moved to the butt joint angle and are bonded through the executing assembly 8, and the straight frame strip is formed with double clamping to resist the subsequent drilling impact, and finally the coaxial through inclined hole at the butt joint is processed by the drilling equipment 3, and the batch production is realized by replacing the frame strip or rotating the straight frame strip to repeat the process.

[0045] Specifically, the working process of the aluminum alloy door and window production positioning drilling device is as follows:

[0046] Precautions: The three-dimensional circular arc aluminum alloy door and window outer frame is composed of two arc-shaped frame strips and two straight frame strips, the end of each frame strip is butt jointed through a 45-degree chamfered surface, and the device needs to complete the coaxial through inclined hole processing at the butt joint to ensure the sealing performance and structural strength in subsequent assembly;

[0047] Firstly, two straight frame strips are placed in parallel into the sinking groove of the placing table 62 of the profile laying assembly 6, the outer side surface of the straight frame strip is abutted against the front and rear side groove walls of the sinking groove, then the limiting plate 64 is inserted into the corresponding insertion port on the bottom surface of the placing table 62 according to the width specification of the straight frame strip, so as to limit the width of the two straight frame strips (the aluminum alloy door and window frame strip is basically standardized in size, and the limiting method has strong adaptability), the rotating clamping air cylinder 65 at the four corners of the placing table 62 is started, the pressure arm of the rotating clamping air cylinder 65 is rotated and pressed down and tightly abuts against the top surface of the two straight frame strips, so as to prevent the straight frame strips from being lifted or moving laterally when moving, then the driving air cylinder 61 installed on the top surface of the workbench 1 pushes the placing table 62 to slide forward along the rail strip 63 on the two sides of the middle frame groove 71 until one of the straight frame strips on the placing table 62 (i.e. the straight frame strip located at the rear part of the top surface of the placing table 62) is displaced to the corresponding processing area in the middle frame groove 71;

[0048] It should be noted that the two straight frame strips are located at the initial position of the end of the profile roller conveying assembly 5, and need to be flush with the left side up and down of the middle frame groove 71, so as to ensure that the pushing distance of the torsion spring lever plate 72 can align the straight frame strip with the arc-shaped frame strip at the opposite corners;

[0049] Secondly, one end of a single arc-shaped frame strip is inserted into the feeding end of the front base table 51 of the profile roller conveying assembly 5, the driving motor of the front base table 51 is started, the internal guide roller 52 is slowly rotated, the arc-shaped frame strip is gradually pushed forward and enters the area between the front base table 51 and the rear base table 51 by the conveying force of the guide roller 52, and then the one end (butt joint end) of the arc-shaped frame strip reaches the processing point of the positioning cross beam 56 (for reference to Figure 10

[0050] ​At this time, the photoelectric sensor 58 at the rear of the positioning beam 56 detects the edge of the arc-shaped frame strip docking end. After sensing that the end is in place, it immediately sends a signal to control the drive motor of the front base platform 51 to stop rotating. The arc-shaped frame strip is then in a stable clamping and fixed state, waiting for the subsequent diagonal docking process with the straight frame strip.

[0051] It should be noted that the extrusion roller 53 on the upper side inside the front base platform 51 (including the rear base platform 51) presses down on the top surface of the arc-shaped frame strip through an elastic clamping structure composed of a sliding groove, a slider, and a spring column; the spring top column 54 on the inner side of the two base platforms 51 pushes the contact pressure roller 55 to fit against the side wall of the arc-shaped frame strip, limiting its lateral displacement and ensuring that the arc-shaped frame strip is in a stable clamping state before being conveyed.

[0052] Third, activate the adjustment component 4 on the top of the extension platform 2. The electric slide rail 41 is an arc-shaped slide rail (adapted to a 45-degree angle adjustment trajectory). It drives the sliding block 42 to slide along the arc-shaped trajectory. The positioning platform 43 at the top of the moving block 42 moves synchronously until the drill bit axis of the drilling device 3 on the top of the reference platform 44 is perpendicular to the diagonal (45-degree oblique section) of the above-mentioned positioned arc-shaped frame. Then, turn off the electric slide rail 41 to complete the angle adjustment.

[0053] At this time, the position sensor installed on the moving block 42 detects that the reference stage 44 has moved to the preset position and immediately sends an electrical signal to the execution component 8 to trigger the clamping and docking action before drilling.

[0054] Fourth, in sync with the third step, after the execution component 8 receives the position sensor signal, the hydraulic rod 84 on the side of the worktable 1 retracts, driving the trigger rod 81 connected to its telescopic end to move into the worktable 1 (the support frame 85 ensures that the trigger rod 81 slides horizontally and avoids sagging deviation). The trigger rod 81 simultaneously drives the abutting protrusion 82 on the rod body and the lifting base 83 at the end to move into the worktable 1.

[0055] First, during the movement of the trigger rod 81, the abutment protrusion 82 contacts the lower force-bearing end of the torsion spring lever plate 72 inside the middle frame groove 71. As the trigger rod 81 continues to advance, the abutment protrusion 82 pushes the torsion spring lever plate 72, causing it to rotate slightly. The upper abutment end of the torsion spring lever plate 72 (covered with a rubber pad to prevent scratching the frame strip) adheres to the bottom wall of the straight frame strip in the pre-positioned state. Through the small thrust generated by the rotation, the straight frame strip is pushed towards the positioned curved frame strip, achieving the 45-degree diagonal contact between the diagonal of the straight frame strip and the diagonal of the curved frame strip (see reference). Figure 11 As shown in 11-1, where the arrow direction indicates the angle direction to be drilled, and the drilling direction is perpendicular to the docking angle between the two.

[0056] It should be noted that the two positioning sensors 57 on the positioning beam 56 can help determine the pre-positioning status of the straight frame strip. When the positioning sensor 57 detects that both sides of the straight frame strip have entered the preset detection area, it determines that the straight frame strip has been in place and sends a signal to ensure the positional accuracy of the straight frame strip before it docks with the curved frame strip.

[0057] Secondly, while the torsion spring lever plate 72 pushes the straight frame bar, the lifting base 83 at the end of the trigger rod 81 (with a through-hole in the middle to avoid interference with the torsion spring lever plate 72) moves to directly below the clamping platform 73. The front inclined surface of the lifting base 83 gradually enters the bottom of the clamping platform 73 until the bottom of the clamping platform 73 is in contact with the rear plane of the lifting base 83. The lifting base 83 smoothly pushes the clamping platform 73 upward in the middle frame groove 71. The lifted clamping platform 73 will move the top electric gripper 732 to the position of the two side walls of the straight frame bar in the positioning state. The lifting action of the clamping platform 73 triggers the opening switch of the electric gripper 732, and the gripper closes to clamp the two side walls of the straight frame bar. At this time, the straight frame bar is in a dual clamping state of being fixed vertically by the rotating clamping cylinder 65 and clamped horizontally by the electric gripper 732, which can effectively resist the axial impact force during drilling.

[0058] Finally, start the drilling equipment 3. Driven by the electric push rod 45, the drill bit feeds towards the joint and completes the coaxial through-hole machining of the straight frame bar and the side wall of the arc frame bar in one go.

[0059] Fifth, after the above processing is completed, the actuator 8 retracts (the hydraulic rod 84 extends, driving the trigger rod 81 and the lifting base 83 to reset), and the torsion spring lever plate 72 resets under the action of its own torsion spring force, while driving the processed straight frame strip to reset.

[0060] Then, the drive cylinder 61 is activated, pushing the placement table 62 to slide backward along the rails 63 on both sides of the middle frame groove 71 until another straight frame bar (the straight frame bar located on the front side of the top of the placement table 62) is moved to the corresponding processing area of ​​the middle frame groove 71; at the same time, the drive motor of the front base table 51 is restarted, driving the arc-shaped frame bar clamped on it to transfer and transport to the rear base table 51, thereby using the rear base table 51 for clamping. When the arc-shaped frame bar is transferred again, its other diagonal end (the unprocessed diagonal) will enter the processing area of ​​the positioning beam 56 and be sensed into place by the front photoelectric sensor 58, and the arc-shaped frame bar is repositioned and clamped by the rear base table 51; then, the adjustment component 4 drives the drilling device 3 to move to the mirror position through the electric slide rail 41, changing the drilling angle, and the execution component 8 is activated again to push and clamp, aligning the other straight frame bar with the arc-shaped frame bar diagonally (see reference). Figure 11As shown in 11-2, where the arrow indicates the angle direction to be drilled (the drilling direction is perpendicular to the joint angle of the two), the processing of two opposite corners of a single curved frame strip and the processing of one opposite corner of two straight frame strips are completed. Finally, a new curved frame strip is replaced, and the two straight frame strips with the processed single ends are flipped and rearranged. The above steps are repeated to complete the drilling of all opposite corners of the door and window frame, achieving efficient mass production.

[0061] Please see Figure 4 and Figure 7 The workbench 1 is equipped with an execution assembly 8 that triggers the rotation of the torsion spring lever plate 72 and the lifting of the clamping platform 73. The execution assembly 8 includes a trigger rod 81, an abutment protrusion 82, and a lifting base 83. The trigger rod 81 slides on the side of the workbench 1, and one end of the trigger rod 81 is fixedly connected to the telescopic end of the hydraulic rod 84. The hydraulic rod 84 is installed on the same side of the workbench 1 as the trigger rod 81. The abutment protrusion 82 is installed on the rod body of the trigger rod 81. When the trigger rod 81 is driven to move by the hydraulic rod 84, the abutment protrusion 82 moves accordingly and abuts against the force-bearing end of the lower part of the torsion spring lever plate 72. The lifting base 83 is installed on the inward end of the trigger rod 81. The middle part of the lifting base 83 has a through-hole for avoiding the torsion spring lever plate 72. When the trigger rod 81 moves, the lifting base 83 moves accordingly and pushes the clamping platform 73 to rise, thereby clamping the straight frame bar after displacement.

[0062] Furthermore, a support frame 85 is installed on the side wall of the workbench 1, and the top of the support frame 85 is slidably connected to the trigger rod 81.

[0063] In the preferred embodiment of this solution, by setting up a trigger rod 81, abutting protrusions 82, lifting base 83, hydraulic rod 84, and support frame 85, a single hydraulic rod 84 drives an integrated trigger rod 81. The abutting protrusions 82 and lifting base 83 at different positions on the rod trigger the rotation of the torsion spring lever plate 72 and the lifting of the clamping platform 73 in a strict sequence. This ensures the correct process flow of first accurately pushing the straight frame strip to complete the docking and then rigidly clamping it, avoiding positioning deviations or processing interference caused by disordered action sequence, and ensuring the reliability of processing.

[0064] Meanwhile, when the lifting base 83 pushes the clamping table 73 to rise, and the electric gripper 732 clamps the straight frame bar from both sides, it together with the original rotating clamping cylinder 65 above to form a multi-directional composite clamping of the workpiece, providing extremely strong rigid support for the straight frame bar, which can effectively resist the huge radial force and vibration generated during drilling, effectively ensuring the machining accuracy and hole wall quality of the through hole, and preventing the workpiece from shifting or vibrating during the processing.

[0065] Please see Figures 8-10The profile roller conveying assembly 5 includes: a base platform 51, of which two are fixedly installed on the front and rear sides of the top surface of the worktable 1; guide rollers 52, installed on the lower side inside the base platform 51, and each guide roller 52 is connected to a corresponding drive motor for driving; a pressing roller 53, installed on the upper side inside the base platform 51 through an elastic pressing structure, and located above the guide rollers 52. The elastic pressing structure adopts the cooperation of a sliding groove, a slider and a spring column, so that it can elastically press against the arc-shaped frame strip on the guide roller 52; and a spring top column 54, slidably installed on the base platform 51, and the end of the spring top column 54 is equipped with a contact pressure roller 55 for rolling against the side end face of the arc-shaped frame strip from the side.

[0066] In the preferred embodiment of this solution, a base platform 51, guide rollers 52, extrusion rollers 53, spring top posts 54, and contact pressure rollers 55 are provided. The guide rollers 52 provide driving power, which, together with the upper elastically pressing extrusion rollers 53, forms a vertical flexible clamping, and the side spring top posts 54 and contact pressure rollers 55 form a horizontal flexible limiting, together forming a stable conveying channel. This multi-directional constraint effectively prevents the arc-shaped frame from jumping, slipping, or twisting during the conveying process, ensuring that it can be smoothly and accurately fed into the processing area, laying a solid foundation for subsequent precise docking.

[0067] Meanwhile, the distributed layout of the two base platforms 51 provides stable support for the long arc-shaped frame strip. Combined with its smooth conveying characteristics, the front end of the arc-shaped frame strip can be repeatedly and accurately conveyed to the preset processing point. With the cooperation of detection elements such as photoelectric sensor 58, the entire process from feeding and conveying to preliminary positioning is automated, reducing the reliance on manual operation, which not only improves efficiency but also ensures the consistency of processing benchmarks.

[0068] Please see Figure 8 , Figure 9 , Figure 12 and Figure 13 A positioning beam 56 is fixedly connected between the two base platforms 51; two positioning sensors 57 are symmetrically installed on the inner middle of the top of the positioning beam 56 to assist in positioning the processing position of the straight frame strip; two photoelectric sensors 58 are symmetrically installed on the outer middle of the top of the positioning beam 56 to detect the rotation status of the curved frame strip's butt corner edge.

[0069] In the preferred embodiment of this solution, the positioning beam 56, positioning sensor 57, and photoelectric sensor 58 are integrated on the integrated positioning beam 56. This allows for the simultaneous and automatic detection of the left and right boundary positions of the straight frame strip and the rotational positioning status of the curved frame strip end, providing crucial positional feedback information for the entire automated processing flow and ensuring the accuracy of subsequent docking and drilling.

[0070] The two symmetrically installed positioning sensors 57 work together to detect the two sides of the straight frame strip and determine whether it is within the preset correct positioning range. The photoelectric sensor 58 is specifically used to detect the end edge of the curved frame strip. When it senses that the curved frame strip has been rotated and conveyed to the preset processing point, it can immediately send a signal to stop the conveying drive. This ensures that the curved frame strip can always stop accurately with a consistent posture, preparing for the next step of aligning with the 45-degree bevel of the straight frame strip.

[0071] Please see Figure 5 The profile flattening assembly 6 includes: a drive cylinder 61, installed on the top surface of the workbench 1; a placement platform 62, slidably disposed on the top surface of the workbench 1, with the rear end of the placement platform 62 fixedly connected to the telescopic end of the drive cylinder 61; a track bar 63, arranged in pairs on the front and rear sides of the middle frame groove 71, with the bottom of the placement platform 62 slidingly engaged with the track bar 63; a recessed groove is provided in the middle of the placement platform 62, and multiple insertion interfaces are provided on the front and rear sides of the bottom surface of the recessed groove, with a limit plate 64 inserted and removed into the insertion interfaces; and a rotary clamping cylinder 65, installed at the four corners of the bottom surface of the recessed groove.

[0072] In the preferred embodiment of this solution, the drive cylinder 61, placement platform 62, track bar 63, limiting plate 64, and rotary clamping cylinder 65, by setting multiple sets of plug-in interfaces on the bottom surface of the sinking tank and cooperating with the pluggable limiting plate 64, provide a modular and selectable lateral positioning reference for standardized straight frame bars of different widths. The operator only needs to select the corresponding plug-in interface according to the profile specifications and insert it into the limiting plate 64 to quickly complete the precise limiting in the width direction, which greatly simplifies the adjustment steps, shortens the preparation time, and improves the adaptability and production efficiency of the equipment to different batches of workpieces within a certain range.

[0073] The straight frame strip is clamped from above by arranging rotary clamping cylinders 65 at the four corners of the placement table 62. This four-point symmetrical clamping method ensures the uniform distribution of clamping force and effectively prevents warping or vibration that may occur during the processing of the straight frame strip. It provides crucial rigidity for the subsequent drilling process, thereby ensuring the drilling quality.

[0074] Please see Figure 2 and Figure 3 The adjustment component 4 includes: an electric slide rail 41, which is installed on the top of the extension platform 2, and a moving block 42 slides on the electric slide rail 41; a positioning platform 43 is installed on the top of the moving block 42, a reference platform 44 slides on the top of the positioning platform 43, and a drilling device 3 is installed on the top of the reference platform 44; an electric push rod 45 is installed on the side of the positioning platform 43, and the telescopic end of the electric push rod 45 is fixedly connected to the side of the reference platform 44.

[0075] Furthermore, the hydraulic rod 84 is electrically connected to a position sensor mounted on the movable block 42. When the movable block 42 slides to a preset angle, the position sensor sends a signal to control the hydraulic rod 84 to move.

[0076] In a preferred embodiment of this solution, the electric slide rail 41, the moving block 42, the positioning table 43, the reference table 44, and the electric push rod 45, driven by the electric slide rail 41 mounted on the extension table 2, can drive the moving block 42 to move the entire drilling equipment 3 smoothly along a predetermined trajectory (such as an arc trajectory adapted to 45 degrees), and quickly and accurately position it to the required processing angle (i.e., the position where the drill axis is perpendicular to the 45-degree oblique cut surface of the workpiece).

[0077] Meanwhile, the adjustment component 4 and the execution component 8 (hydraulic rod 84, etc.) are electrically connected through a position sensor. When the drilling equipment 3 is adjusted to the correct position, the system can automatically trigger the subsequent clamping and docking actions, reducing intermediate pauses and manual intervention, and achieving high precision, high efficiency and high automation in drilling processing, thereby ensuring the consistency of product quality in mass production.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
