Description

Technical Field

[0001] This utility model relates to the field of door and window fixing technology, and more specifically, to a fixing device for manufacturing aluminum alloy doors and windows. Background Technology

[0002] In the production process of aluminum alloy doors and windows, the assembly of the door and window frames is the core link that directly affects the final quality of the product. The assembly precision not only determines the sealing performance and structural stability of the doors and windows, but is also closely related to their service life and installation compatibility.

[0003] In the manufacturing process of aluminum alloy doors and windows, the precise splicing of two profiles at specific angles (such as 90°, 120°, etc.) is a crucial step that determines the squareness, structural stability, and sealing performance of the door and window frame. Traditional assembly methods generally rely on manual operation: first, workers need to use an angle gauge or simple tooling to make rough measurements and positioning; then, they rely on their personal experience to judge whether the angle is accurate; next, they use tools such as C-clamps and quick clamps to temporarily fix the profiles; and finally, they perform connection operations such as drilling, tightening bolts, or welding.

[0004] Differences can occur between different workers, and even among the same worker in different batches. Visual observation and manual positioning inevitably introduce errors. During fixing and connection, profiles are prone to shifting, leading to poor angle consistency in mass-produced door and window frames. Angle deviations, such as greater than or less than 90°, directly affect the fit of subsequent glass installation and the sealing performance of the finished product. Even rework and adjustment not only increase labor costs but may also damage the profile surface. When using clamps to fix a single profile, the end of the other profile to be spliced ​​is easily slightly offset under gravity or external force, making it difficult to ensure the theoretically required tight, seamless contact between the splicing ends of the two profiles. Such gaps at the splice not only affect aesthetics but also weaken the overall structural strength of the doors and windows, becoming a potential hazard for future ventilation and leakage. Therefore, we propose a fixing device for aluminum alloy door and window manufacturing. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a fixing device for the manufacture of aluminum alloy doors and windows, so as to solve the technical problem that the profiles are easy to shift during the current manual positioning, resulting in inconsistent angles of the door and window frames and gaps in the splicing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fixing device for manufacturing aluminum alloy doors and windows, including a first flip frame and a second flip frame, a pressing and correcting mechanism, and an angle positioning mechanism. The first flip frame and the second flip frame are hinged together by a hinge shaft. The inner sides of the first flip frame and the second flip frame form a cavity for accommodating a door and window frame. The pressing and correcting mechanism includes a lower pressure frame and a lower pressure wheel. The lower pressure frame is slidably installed inside the first flip frame and the second flip frame, and is rotatably installed inside the lower pressure frame. The wheel surface of the lower pressure wheel protrudes from the lower pressure frame and faces the inside of the cavity. The circumferential surface of the pressure roller is provided with a spiral strip. The angle positioning mechanism includes a rotating frame and a sliding block. The sliding block is slidably installed in the rotating frame. The rotating frame is provided with at least one limiting groove. The sliding block is provided with a receiving cavity. The receiving cavity is provided with an elastic element and a ball ball partially pushed out by the elastic element. When the sliding block moves to the corresponding position, the ball ball can be partially embedded in the limiting groove. The angle positioning mechanism is used to adjust and lock the included angle between the first flipping frame and the second flipping frame. The pressing and correction mechanism is used to press and automatically position the door and window frame placed in the cavity at the set included angle.

[0007] Preferably, the clamping and correction mechanism further includes a first spring, which is fixedly installed between the first and second flipping frames and the lower pressure frame, and a guide head is fixedly installed on the outer end of the lower pressure frame.

[0008] Preferably, the angle positioning mechanism further includes a rotating block, which is rotatably mounted on the top of the first flipping frame. A lower pressure frame is rotatably mounted inside the rotating block, and a knob is fixedly mounted at the end of the lower pressure frame. The rotating frame is rotatably mounted on the top of the second flipping frame, and the sliding block is threadedly mounted on the outside of the threaded rod.

[0009] Preferably, the opening of the guide head is provided with a guide slope to facilitate the insertion of the door and window frame.

[0010] Preferably, the elastic element is a second spring and a telescopic block, the second spring is fixedly installed between the telescopic block and the inner wall of the accommodating cavity, and the ball bearing is rotatably installed at the end of the telescopic block.

[0011] Preferably, the rotating frame has multiple limiting grooves, which are arranged at intervals on the inner wall of the rotating frame.

[0012] Preferably, the first flipping frame is provided with a first mounting cavity, and the second flipping frame is provided with a corresponding second mounting cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses ball bearings embedded in the limiting groove to quickly lock the angles of the first and second flip frames, eliminating the need for manual visual judgment and avoiding differences in operation between different workers or batches. This ensures uniform angles of door and window frames produced in batches. When the frame pushes the pressure roller upwards, the first spring stores energy and continuously squeezes the profile through the pressure roller. Combined with the guide head guiding the inclined surface to accurately guide the frame, this not only prevents the profile from shifting during fixing and connection, reducing manual positioning errors, but also eliminates the need for frequent rework and adjustments, saving labor costs and avoiding damage to the profile surface during rework. It also provides a basic guarantee for the fit of subsequent glass installation, solving the problem of inconsistent door and window frame angles and gaps caused by easy profile shifting during current manual positioning.

[0014] 2. This utility model also utilizes the lateral thrust generated by the spiral strip around the circumference of the pressure wheel as the wheel rotates. This thrust can automatically fit the profile into the inner reference wall of the first and second flip frames. Even when fixing a single profile, this thrust can limit the end displacement of the other profile to be spliced, ensuring that the splicing end faces of the two profiles are in close contact. This not only improves the appearance but also enhances the overall structural strength of the doors and windows, eliminating the potential for drafts and leaks during future use.

[0017] Example: Figures 1 to 5As shown, this utility model relates to a fixing device for manufacturing aluminum alloy doors and windows, including a first flip frame 1 and a second flip frame 2, a pressing and correcting mechanism 3, and an angle positioning mechanism 4. The first flip frame 1 and the second flip frame 2 are hinged together by a hinge shaft. The inner sides of the first flip frame 1 and the second flip frame 2 form cavities for accommodating door and window frames. The first flip frame 1 is provided with a first mounting cavity 11, and the second flip frame 2 is provided with a corresponding second mounting cavity 21. The pressing and correcting mechanism 3 includes a lower pressure frame 32 and a lower pressure wheel 34. The lower pressure frame 32 is slidably installed inside the first flip frame 1 and the second flip frame 2, and the lower pressure frame 32 is rotatably installed. Inside the lower pressure frame 32, the wheel surface of the lower pressure roller 34 protrudes from the lower pressure frame 32 and faces the inner side of the cavity. The circumferential surface of the lower pressure roller 34 is provided with a spiral strip 35. The angle positioning mechanism 4 includes a rotating frame 43 and a sliding block 44. The sliding block 44 is slidably installed in the rotating frame 43. The rotating frame 43 is provided with at least one limiting groove 45. The sliding block 44 is provided with a receiving cavity. The receiving cavity is provided with an elastic element and a ball 443 partially ejected by the elastic element. The elastic element is a second spring 441 and a telescopic block 442. The second spring 441 is fixedly installed between the telescopic block 442 and the inner wall of the receiving cavity. The ball 443 is rotatably installed on the telescopic block 442. At the end of block 442, the ball bearing 443 can partially embed into the limiting groove 45 when the sliding block 44 moves to the corresponding position. There are multiple limiting grooves 45 on the rotating frame 43, which are spaced apart on the inner wall of the rotating frame 43. The angle positioning mechanism 4 is used to adjust and lock the included angle between the first flipping frame 1 and the second flipping frame 2. The pressing and correction mechanism 3 is used to press and automatically position the door and window frame placed in the cavity at the set included angle. In this utility model, the threaded rod 42 drives the sliding block 44 to move, so that the ball bearing 443 embeds into the limiting groove 45, quickly locking the angle between the first flipping frame 1 and the second flipping frame 2 without the need for manual visual judgment. To avoid differences in operation between different workers or batches and ensure uniformity of door and window frame angles in mass production, the first spring 31 stores energy and continuously compresses the profile through the lower pressure roller 34 when the frame pushes the lower pressure roller 34 upward, in conjunction with the guide head 33 to guide the inclined auxiliary frame for precise insertion. This not only avoids the profile shifting during fixing and connection, reducing manual positioning errors, but also eliminates the need for frequent rework and adjustment, saving labor costs and avoiding damage to the profile surface during rework. It also provides a basic guarantee for the fit of subsequent glass installation, solving the problem of inconsistent door and window frame angles and gaps in splicing caused by easy profile shifting during current manual positioning.

[0018] Furthermore, the clamping and correction mechanism 3 also includes a first spring 31, which is fixedly installed between the first flipping frame 1, the second flipping frame 2, and the lower pressure frame 32. A guide head 33 is fixedly installed on the outer end of the lower pressure frame 32. The opening of the guide head 33 is provided with a guide slope to facilitate the introduction of the door and window frame. The lower pressure frame 32 cooperates with the first spring 31. When the frame pushes the lower pressure roller 34 to move upward, the first spring 31 stores energy and continuously squeezes the profile through the lower pressure roller 34 to prevent the profile from shifting during the fixing and connection process. At the same time, the guide slope of the guide head 33 assists the frame to be accurately introduced, reducing manual positioning errors and eliminating the need for frequent rework adjustments, which saves labor costs and avoids damage to the surface of the profile caused by rework.

[0019] Furthermore, the angle positioning mechanism 4 also includes a rotating block 41, which is rotatably mounted on the top of the first flipping frame 1. A lower pressure frame 32 is rotatably mounted inside the rotating block 41. A knob 421 is fixedly mounted at the end of the lower pressure frame 32. A rotating frame 43 is rotatably mounted on the top of the second flipping frame 2. A sliding block 44 is threadedly mounted on the outside of the threaded rod 42. The first mounting cavity 11 of the first flipping frame 1 and the second mounting cavity 21 of the second flipping frame 2 provide a convenient channel for fastener installation. When splicing, there is no need to avoid the device components, simplifying the operation steps.

[0020] Working principle: This embodiment provides a fixing device for aluminum alloy door and window manufacturing. In use, the knob 421 is rotated, which drives the threaded rod 42 to rotate, thereby causing the sliding block 44 to slide inside the rotating frame 43, and then causing the ball 443 to move inside the rotating frame 43. When the ball 443 moves to the position of the limiting groove 45, the second spring 441 rebounds, thereby causing the ball 443 to enter the limiting groove 45, thus completing the fixing of the angle of the first flipping frame 1 and the second flipping frame 2.

[0021] The individual frame of the aluminum alloy door and window is placed from the guide head 33 and pushed to the bottom of the pressure roller 34. The frame is pushed inward, and the pressure roller 34 is squeezed to move upward. Then, the pressure frame 32 squeezes the first spring 31, so that the first spring 31 stores energy and the pressure roller 34 can continuously squeeze the frame.

[0022] Furthermore, during the rotation of the pressure roller 34, the spiral 35 rotates along with the pressure roller 34. This rotating spiral 35 generates a lateral thrust, which automatically and smoothly fits the door and window frame into the inner reference wall of the first flip frame 1 and the second flip frame 2. This automatically ensures that there is no gap between the frame and the reference surface, and the positioning is accurate.

[0023] After placing and fixing the two frames in the first flip frame 1 and the second flip frame 2 respectively, push them towards the middle so that their ends are in close contact at a preset angle. Use bolts or other fasteners to pass through the first mounting cavity 11 on the first flip frame 1 and the second mounting cavity 21 on the second flip frame 2 to fix the matched door and window frames together, thus completing the precise angle assembly.

[0024] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
