Abstract

This invention belongs to the field of door and window opening technology, and particularly relates to an automatic opening structure for processing thermally broken aluminum alloy doors and windows. It includes a rectangular outer frame, a clamping part, a drilling positioning frame, and an electric drill body. The clamping part is located on the lower side of the outer frame and includes two fixing plates, one of which is fixedly positioned on the lower side of the outer frame near the right edge. This invention can quickly fix the drilling structure as a whole within the wall opening, and then fix the position of the door frame to be drilled relative to the wall opening, effectively reducing the micro-displacement of the profile caused by drilling vibration. Furthermore, the drilling positioning frame, with its strict limitation on the electric drill's movement area, prevents the electric drill from exceeding the predetermined area and damaging the thermal insulation strip or reinforcing ribs during drilling. Simultaneously, precise drilling guidance and positioning reduce the damage to the sealing integrity of the thermal insulation strip and the load-bearing structure of the reinforcing ribs caused by drilling deviations, ensuring the thermal insulation performance and wind pressure resistance of the thermally broken aluminum profile, and eliminating structural safety hazards during long-term use.

Description

Technical Field

[0001] This invention belongs to the field of door and window opening technology, and particularly relates to an automatic opening structure for processing thermally broken aluminum alloy doors and windows. Background Technology

[0002] With their superior thermal insulation and structural stability, thermally broken aluminum windows and doors have become the mainstream choice in the building window and door industry. Their installation quality directly determines the sealing performance, service life, and safety factor of the windows and doors. In the standardized installation process, the door frame must first be accurately positioned and temporarily fixed inside the wall opening. Then, permanent fixing is achieved through the alignment and connection of the pre-set installation holes in the door frame with the pre-embedded holes in the wall opening. This alignment installation step is the core prerequisite for ensuring the installation accuracy of the windows and doors.

[0003] In actual construction scenarios, due to errors in wall construction, deviations in door frame processing, and cumulative errors in installation positioning, the pre-set installation holes in the door frame and the pre-embedded holes in the wall often exhibit positional discrepancies, requiring hole enlargement or re-drilling to achieve a proper fit. To improve construction efficiency, the industry commonly adopts on-site drilling without dismantling the door frame, where operators use handheld electric drills to drill holes in the temporarily fixed door frame. However, this method has significant technical bottlenecks: on the one hand, drilling accuracy relies entirely on the operator's experience and skill; for non-standard hole positions such as irregularly shaped or elongated holes, the drilling path is difficult to control precisely, easily leading to problems such as hole position deviation and irregular hole diameter; on the other hand, the stability of the temporarily fixed door frame is insufficient, and drilling vibration can easily cause slight displacement of the profile, further exacerbating drilling deviations.

[0004] Crucially, the core advantage of thermally broken aluminum profiles relies on the complete structure of the internal thermal insulation strip and reinforcing ribs. However, the aforementioned drilling deviations can easily damage the sealing integrity of the thermal insulation strip or disrupt the load-bearing structure of the reinforcing ribs, leading to decreased thermal insulation performance, weakened wind pressure resistance, and even long-term structural safety hazards. The limitations of current manual hand-held drilling methods have become a key technical bottleneck hindering the standardization and large-scale improvement of thermally broken aluminum window and door installation quality. There is an urgent need for an automated processing structure that adapts to on-site construction scenarios and improves drilling accuracy, solving the stability and precision issues of drilling profiles in temporarily fixed states. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an automatic hole-opening structure for processing thermally broken aluminum alloy doors and windows, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: The present invention provides an automatic drilling structure for processing thermally broken aluminum alloy doors and windows, comprising a rectangular outer frame, a clamping part, a drilling positioning frame, and an electric drill body. The clamping part is located on the lower side of the outer frame and includes two fixed clamping plates. One fixed clamping plate is fixedly located on the lower side of the outer frame, and the other fixed clamping plate is slidably located on the lower side of the outer frame via a first locking member. Positioning clamping plates are provided on both fixed clamping plates via second locking members, and two auxiliary positioning frames are provided on each of the two second locking members. The drilling positioning frame includes two sliding components located on the upper side of the outer frame and symmetrically arranged front and rear. The two sliding components are connected to a positioning slide frame, and a sliding frame is provided on the positioning slide frame. An electric drill chuck is connected to the sliding frame via multiple spring telescopic rods. The electric drill body is detachably mounted on the electric drill chuck. The sliding frame is also provided with four limiting members, which limit the sliding position of the electric drill chuck. The automatic drilling structure is locked inside the wall opening by two fixed clamps. Then, two positioning clamps are used to lock the automatic drilling structure to the door and window profile to be drilled inside the wall opening, realizing the interlocking of the wall opening, door and window profile and automatic drilling structure. Then, the electric drill body on the positioning slide frame is accurately centered and positioned relative to the door and window profile by an auxiliary positioning frame. The drilling range of the electric drill body is accurately limited by four limiting pieces in cooperation with the sliding frame.

[0007] According to an advantageous embodiment, the lower end of the fixing clamp is stepped.

[0008] According to an advantageous embodiment, the first locking member includes a first locking rod rotatably disposed on the left side frame of the outer frame, one end of the first locking rod being rotatably connected to a corresponding fixed clamping plate, and two first guide rods symmetrically disposed on the lower side of the outer frame, the first guide rods being slidably connected to the corresponding fixed clamping plate.

[0009] According to an advantageous embodiment, a diagonal brace is also slidably connected to the first guide rod, and the diagonal brace is fixedly connected to a corresponding fixed clamping plate.

[0010] According to an advantageous embodiment, the second locking member includes a second locking rod threaded in the middle of the fixed clamping plate, one end of the second locking rod being rotatably connected to the corresponding positioning clamping plate, and two second guide rods symmetrically connected to the front and rear of the positioning clamping plate, the second guide rods being slidably connected to the corresponding fixed clamping plate.

[0011] According to an advantageous embodiment, the auxiliary positioning frame includes a first slider slidably disposed on a second guide rod, an L-shaped push plate fixedly disposed on the first slider, and a return spring sleeved on the surface of the second guide rod, the two ends of the return spring being fixedly connected to the corresponding first slider and positioning clamp respectively.

[0012] According to an advantageous embodiment, the sliding assembly includes a slide rail fixedly mounted on the upper side of the outer frame, a slide block slidably mounted on the slide rail, spring limit pins on both the left and right sides of the slide rail, and a first locking bolt threaded on the slide block, with the positioning slide frame fixedly connected to the two slide blocks.

[0013] According to an advantageous embodiment, the sliding frame includes two third guide rods fixedly disposed on the upper side of the positioning slide frame and symmetrically arranged front and back. A second slider is slidably disposed on the third guide rod. A rectangular frame is disposed between the two second sliders. The rectangular frame is formed by bending and connecting circular rod tubes. A connecting slide plate is slidably disposed on both long sides of the rectangular frame. The connecting slide plate is fixedly connected to one end of the spring telescopic rod.

[0014] According to an advantageous embodiment, the limiting member includes a limiting slide plate, the upper side of which is threaded with a second locking bolt. Two limiting slide plates in one set of limiting members are slidably disposed on the surface of one of the long sidewalls of the rectangular frame, and the corresponding connecting slide plate is located between the two corresponding limiting slide plates. Two limiting slide plates in another set of limiting members are slidably disposed on the surface of one of the third guide rods, and the corresponding second slider is located between the two corresponding limiting slide plates.

[0015] According to an advantageous embodiment, the electric drill clamp includes a base plate fixedly connected to one end of a spring telescopic rod, a socket cylinder fixedly mounted on the base plate, a through hole coaxial with the socket cylinder on the base plate, and a plurality of wedge-shaped claws rotatably mounted on the peripheral side wall of the socket cylinder, a torsion spring being provided between the rotating shaft and the socket cylinder, and a locking sleeve being threadedly connected to the surface of the socket cylinder.

[0016] Compared with existing technologies, the automatic drilling structure for processing thermally broken aluminum alloy doors and windows provided in this invention has the following beneficial effects: 1. In this invention, by cooperating with the clamping part and the drilling positioning frame, on-site drilling can be completed without disassembling the temporarily fixed door frame. First, the drilling structure is fixed as a whole in the wall opening, and then the position of the door frame to be drilled is fixed relative to the wall opening, realizing the interlocking of the drilling structure, door and window profiles, and wall opening, which greatly improves the stability during drilling and effectively reduces the micro-displacement of the profiles caused by drilling vibration. Furthermore, by using the drilling positioning frame to strictly limit the moving area of ​​the electric drill body, the drilling trajectory of the electric drill body is precisely controlled, avoiding the electric drill from exceeding the predetermined area and damaging the thermal insulation strip or reinforcing ribs during drilling, reducing the damage of drilling deviation to the sealing integrity of the thermal insulation strip and the load-bearing structure of the reinforcing ribs, ensuring the thermal insulation performance and wind pressure resistance of the thermally broken aluminum profiles, and eliminating structural safety hazards in long-term use.

[0017] 2. In this invention, the double fixing clamping plate of the clamping part is used in conjunction with the positioning clamping plate to achieve double fixing. On the one hand, the opening structure is firmly locked in the wall hole, and on the other hand, the door frame is accurately clamped in the area to be drilled. At the same time, the triangular support structure formed by the diagonal bracing structure further improves the fixing stability, effectively weakens the micro-displacement of the profile caused by drilling vibration, and reduces the impact of cumulative error on drilling accuracy from the root.

[0018] 3. In this invention, the adjustable limiting structure of the drilling positioning frame enables precise adjustment of the position of the electric drill body and locking of the active area. Whether drilling at a single point or processing non-standard holes within a predetermined area, the drilling path can be precisely controlled, avoiding problems such as hole position deviation and irregular hole diameter caused by manual hand-held electric drill.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will now be described in further detail.

[0026] Please refer to the following: Figure 1 An automatic drilling structure for processing thermally broken aluminum alloy doors and windows includes a rectangular outer frame 1, a clamping part 2 disposed on the lower side of the outer frame 1, and a drilling positioning frame 3 slidably disposed on the upper side of the outer frame 1. The drilling positioning frame 3 is equipped with a detachable electric drill body 4.

[0027] In actual operation, the entire hole-opening structure is fixed to one side of the wall hole by the clamping part 2, and the position of the electric drill body 4 is adjusted by the drilling positioning frame 3. The movable area of ​​the electric drill body 4 is adjusted and limited, so that the electric drill body 4 can guide drilling at a single point or move freely within a predetermined area to guide drilling, which can improve drilling accuracy and prevent the electric drill body 4 from exceeding the predetermined area during the milling process and causing accidental damage to the door and window profiles.

[0028] See Figures 1-4 To facilitate overall fixation and prevent the door frame profile inside the wall opening from shaking or shifting during drilling, the clamping part 2 in this solution includes two fixing plates 21. One fixing plate 21 is welded to the lower side of the outer frame 1 near the right edge, and the other fixing plate 21 is slidably disposed on the lower side of the outer frame 1 via a first locking member 22. The two fixing plates 21 are engaged on both sides of the wall and locked under the drive of the first locking member 22, thus fixing the automatic hole-opening structure as a whole in the predetermined position of the wall opening. Each of the two fixing plates 21 is provided with a positioning clamp 24 via a second locking member 23, and each of the two second locking members 23 is provided with two auxiliary positioning brackets 25.

[0029] In specific work, this solution takes drilling holes in the lower frame profile of a door frame as an example: When fixing the entire device to the predetermined position of the wall hole, firstly, according to the thickness of the wall hole, the sliding fixed clamp 21 is moved by the first locking member 22 to adjust the distance between the two fixed clamps 21 to be close to the thickness of the wall hole; then the entire device is lifted up so that the two fixed clamps 21 are aligned with the predetermined position on the lower side of the wall hole and close to the inner and outer walls of the lower side of the wall hole. Finally, the first locking member 22 drives the two fixed clamps 21 to fit and lock with the inner and outer walls of the lower side of the wall hole, so that the entire device is fixed on the lower side of the wall hole and located at the position to be drilled on the door frame.

[0030] Then, the two second locking elements 23 control the corresponding positioning clamps 24 to fit against the side wall of the area to be drilled on the door frame profile. The two positioning clamps 24 together clamp and position the area to be drilled on the door frame profile, further ensuring the stability of the door frame profile during drilling. Furthermore, while the positioning clamps 24 move to fit against the door frame profile, they simultaneously move the auxiliary positioning frames 25 closer to the door frame profile. The four auxiliary positioning frames 25 are paired up and correspond to both sides of the drilling positioning frame 3. The two auxiliary positioning frames 25 in each group move closer to each other, jointly pushing the drilling positioning frame 3 towards the center area to be processed on the door and window profile.

[0031] See Figure 3 The lower end of the fixing plate 21 is set in a stepped shape. The vertical and horizontal stepped surfaces on the inner side of the lower end of the fixing plate 21 are respectively attached to two mutually perpendicular surfaces of the wall. This ensures that after the two fixing plates 21 come into contact with the wall, they can be firmly fixed to the wall while also allowing the outer frame 1 to maintain a certain distance from the corresponding surface of the wall.

[0032] See Figure 1 and Figure 4 The first locking component 22 includes a first locking rod 221 rotatably mounted on the left side frame of the outer frame 1. One end of the first locking rod 221 is rotatably connected to the corresponding fixed clamping plate 21. Two first guide rods 222, symmetrically arranged front and rear, are fixedly mounted on the lower side of the outer frame 1. The first guide rods 222 are slidably connected to the corresponding fixed clamping plates 21. A handle is provided on the first locking rod 221. The operator rotates the first locking rod 221 by using the handle, which, with the cooperation of the first guide rods 222, drives one of the fixed clamping plates 21 to approach the other fixed clamping plate 21, so that the two fixed clamping plates 21 are fitted and locked against the inner and outer walls of the wall opening.

[0033] See Figure 1 and Figure 3 To improve the stability of the sliding fixed clamp 21, a diagonal brace 5 is slidably connected to the first guide rod 222, and the diagonal brace 5 is fixedly connected to the corresponding fixed clamp 21. The diagonal brace 5, the fixed clamp 21 and the outer frame 1 together form a triangular support structure, which makes the fixed clamp 21 more stable after it stops sliding.

[0034] See Figure 1 and Figure 3 The second locking element 23 includes a second locking rod 231 threaded into the middle of the fixed clamping plate 21. One end of the second locking rod 231 is rotatably connected to the corresponding positioning clamping plate 24. Two second guide rods 232, symmetrically arranged front and rear, are also fixedly connected to the positioning clamping plate 24. The second guide rods 232 are slidably connected to the corresponding fixed clamping plate 21. The second locking rod 231 is also equipped with a handle. The operator rotates the second locking rod 231 by using the handle, and with the cooperation of the second guide rods 232, the positioning clamping plate 24 is brought closer to the side wall of the profile.

[0035] See Figure 1 and Figure 3In order to facilitate the centering and alignment of the drilling positioning frame 3 with the door frame profile, the auxiliary positioning frame 25 includes a first slider 251 slidably disposed on the second guide rod 232. An L-shaped push plate 252 is fixedly disposed on the first slider 251. A return spring 253 is sleeved on the surface of the second guide rod 232. The two ends of the return spring 253 are fixedly connected to the corresponding first slider 251 and positioning clamp 24 respectively. When the second locking rod 231 drives the corresponding positioning clamp 24 to approach the side wall of the door frame profile, the positioning clamp 24 will synchronously drive the second guide rod 232 to move, so that the first slider 251 and the L-shaped push plate 252 on the second guide rod 232 will move accordingly. When the L-shaped push plate 252 moves and abuts against one side of the drilling positioning frame 3, under the action of the return spring 253, the L-shaped push plate 252 will push the drilling positioning frame 3 to move towards the middle of the profile. The four L-shaped push plates 252 work together on both sides of the drilling positioning frame 3 so that the drilling positioning frame 3 can be positioned as close as possible to the middle of the preset drilling position of the door frame profile.

[0036] See Figure 1 , Figure 3 and Figure 5 To reduce the difficulty of drilling holes in the wall openings of the door frame profile, the drilling positioning frame 3 includes two sliding components 31 that are symmetrically arranged on the upper side of the outer frame 1. The two sliding components 31 are connected to a rectangular positioning slide frame 32. A sliding frame 34 is provided on the positioning slide frame 32. An electric drill chuck 35 is connected to the sliding frame 34 through multiple spring telescopic rods 33. The electric drill body 4 is detachably mounted on the electric drill chuck 35 and moves through the sliding frame 34 and the spring telescopic rods 33. The sliding frame 34 is also provided with four limiting members 36 arranged in pairs. The two sets of limiting members 36 limit the sliding position of the electric drill chuck 35 respectively.

[0037] In actual operation, the drilling positioning frame 3 slides along the outer frame 1 via the sliding assembly 31. While the door frame profile is held by the two positioning clamps 24, the positioning slide frame 32 is centered by the four L-shaped push plates 252. Furthermore, the sliding assembly 31 can further lock the positioned slide frame 32 onto the outer frame 1 after adjustment, ensuring that it will not easily slide during subsequent drilling.

[0038] When drilling is required at a single point on the lower profile of the door frame, the drill body 4 moves to the designated position along the sliding frame 34 via the drill clamp 35. Then, the drill body 4 is fixed on the sliding frame 34 by two sets of limiting members 36, so that the drill body 4 cannot move. At this time, the worker can hold the drill body 4 and press and push the drill down to open the hole.

[0039] When it is necessary to make a waist hole in the lower profile of the door frame, first, the spacing of one set of limiting members 36 is adjusted to limit the horizontal displacement distance of the drill body 4 in the sliding frame 34. Then, the spacing of another set of limiting members 36 is adjusted to limit the front-to-back displacement distance of the drill body 4 in the sliding frame 34. The distances in both directions coincide with the area where the hole needs to be made. Then, the worker holds the drill body 4 and presses it down to make the hole, and controls the drill body 4 to move along the predetermined area while maintaining the downward pressing posture to complete the waist hole making.

[0040] See Figure 1 and Figure 3 The sliding assembly 31 includes a slide rail 311 fixedly mounted on the upper side of the outer frame 1. A slide block 312 is slidably mounted on the slide rail 311. Spring limit pins 313 are provided on both the left and right sides of the slide rail 311, and a first locking bolt 314 is threaded onto the slide block 312. The positioning slide frame 32 is fixedly connected to the two slide blocks 312. The slide block 312 moves along the slide rail 311. The slide block 312 is limited at both ends of the slide rail 311 by the spring limit pins 313 to prevent it from sliding out of the slide rail 311. After the slide block 312 slides to the designated position, the operator can lock the slide block 312 onto the slide rail 311 by rotating the first locking bolt 314, preventing it from moving.

[0041] See Figure 1 and Figure 5 The sliding frame 34 includes two third guide rods 341 fixedly mounted on the upper side of the positioning slide frame 32 and symmetrically arranged front and back. Second sliders 342 are slidably mounted on the third guide rods 341. A rectangular frame 343 is provided between the two second sliders 342. The rectangular frame 343 is constructed by bending and connecting circular tubes. Connecting slide plates 344 are slidably mounted on both long sides of the rectangular frame 343. The connecting slide plates 344 are fixedly connected to one end of the spring telescopic rod 33. After the drill chuck 35 is connected to the connecting slide plates 344 via the spring telescopic rod 33, the drill chuck 35 can move back and forth along the rectangular frame 343 via the connecting slide plates 344. Simultaneously, the rectangular frame 343 as a whole can slide left and right along the third guide rods 341 via the second sliders 342.

[0042] See Figure 1 and Figure 5The limiting member 36 includes a limiting slide plate 361, with a second locking bolt 362 threaded on its upper side. Two limiting slide plates 361 in one set of limiting members 36 are slidably disposed on the surface of one long sidewall of the rectangular frame 343, with the corresponding connecting slide plate 344 located between the two limiting slide plates 361. Two limiting slide plates 361 in another set of limiting members 36 are slidably disposed on the surface of one of the third guide rods 341, with the corresponding second slider 342 located between the two limiting slide plates 361. The limiting slide plates 361 can slide on the third guide rod 341 or the rectangular frame 343. By adjusting the position of the two limiting slide plates 361 on the third guide rod 341 and then fixing the limiting slide plates 361 by rotating the second locking bolt 362, the left-right sliding trajectory of the second slider 342 is restricted. By adjusting the position of the other two limiting slide plates 361 on one long sidewall of the rectangular frame 343 in the same way, the front-back sliding trajectory of the connecting slide plate 344 is restricted. In order to increase the locking force between the second locking bolt and the third guide rod 341 or the rectangular frame 343, the second guide rod 232 and a long side of the rectangular frame 343 can be provided with slots along their length, and the end of the second locking bolt can abut against the inner wall of the slot.

[0043] It should be noted that, although the slide block 312 is subject to vibration generated by the drill body 4 during operation when it is restricted to slide by the first locking bolt and the limiting slide plate 361 is restricted to move by the second locking bolt, the driving force generated by the vibration is much smaller than the locking force of the first or second locking bolt.

[0044] See Figure 1 and Figure 5 To facilitate the assembly and disassembly of the drill body 4, the drill clamp 35 includes a base plate 351 fixedly connected to one end of a spring telescopic rod 33. A socket cylinder 352 is fixedly mounted on the base plate 351. A through hole coaxial with the socket cylinder 352 is provided on the base plate 351, and multiple wedge-shaped jaws 353 are rotatably mounted on the peripheral wall of the socket cylinder 352 via a rotating shaft. A torsion spring is provided between the rotating shaft and the socket cylinder 352, and a locking sleeve 354 is threadedly connected to the surface of the socket cylinder 352. The drill bit of the drill body 4 is inserted into the socket cylinder 352, so that the drill bit of the drill body 4 abuts against each wedge-shaped jaw 353. The drill rod of the drill bit passes through the through hole on the base plate 351 and is aligned with the surface of the profile. Then, by rotating the locking sleeve 354, it moves along the surface of the socket cylinder 352, so that the locking sleeve 354 abuts against multiple wedge-shaped jaws 353 simultaneously, thus centering the drill body 4 relative to the socket cylinder 352.

[0045] It is important to note that the sliding components involved in this solution, such as the slide block 312, the first slider 251, the second slider 342, the connecting slide plate 344, and the limiting slide plate 361, can utilize rollers, ball bearings, or lubricating oil for friction at their connections. Regular maintenance is essential to ensure smooth and precise sliding. Components involving springs also require regular maintenance or replacement.

[0046] In this solution, the device is first fixed to the wall and the door frame profile is locked by double clamping of the fixed clamping plate 21 and the positioning clamping plate 24 by the clamping part 2. This effectively suppresses the micro-displacement of the profile caused by drilling vibration and avoids secondary deviation caused by temporary instability from the root.

[0047] Furthermore, the adjustable limiting mechanism of the drilling positioning frame 3 can precisely limit the movement range of the electric drill, prevent the drill bit from accidentally slipping out of the predetermined processing area, and avoid damage to key structures such as thermal break strips and reinforcing ribs, thereby ensuring the airtightness, thermal insulation and wind pressure resistance of thermally broken aluminum doors and windows.
