Description

Technical Field

[0001] This utility model belongs to the field of door and window processing technology, specifically relating to an aluminum profile corner assembly machine. Background Technology

[0002] The corner assembly machine is a specialized piece of equipment for producing high-end thermally broken aluminum alloy doors and windows. It is suitable for connecting aluminum doors and windows with corner bracket structures at 90-degree angles. In some regions, it is also called a corner extrusion machine, corner impact machine, or edge corner machine.

[0003] A related technology (publication number CN210817072U) discloses a profile door and window corner assembly machine, including a base. The base has a rectangular groove inside, and a first slider that can slide freely within the groove is provided. The first slider is connected to the inner wall of the groove via a reset device. The top wall of the base has an opening communicating with the rectangular groove. This invention, through the coordinated use of a slider, threaded rod, and nut, allows the abutment and fixed stop to be fixed after clamping the door or window. This method replaces a cylinder, reducing production costs and making it more convenient to use. A spring allows the slider to automatically push the abutment to clamp the door or window. Rubber pads on the fixed stop and abutment increase the friction between them and the door or window, preventing damage to the doorway. Placing the first slider inside the base saves space.

[0004] In existing related technical solutions, the two sets of riveting devices are independent of each other, fixed on both sides of the base. This fixed installation method rigidly limits the spatial position of the riveting devices, resulting in a loss of adjustability. However, in the actual processing of aluminum profiles for doors and windows, especially when dealing with corner assembly tasks of aluminum profiles of different sizes and specifications, the precise position of the riveting needs to be flexibly adjusted according to the specific dimensional parameters of the profile, based on the requirements of the processing technology, to ensure that the riveting points can accurately act on the key connection parts of the aluminum profile, thereby ensuring the quality and stability of the corner assembly. However, because the position of the riveting devices in the current technology is fixed, it cannot adapt to diverse processing needs. Even if the positions of the two sets of riveting devices are adjusted, since they are adjusted separately and in isolation, there is a lack of effective synchronous adjustment mechanisms and precise positioning references. After adjustment, it is difficult to ensure that the two sets of riveting devices can maintain an ideal symmetrical relationship. Deviations in the riveting position will cause quality problems such as misalignment and uneven gaps in the corner connection of the aluminum profile, affecting the overall performance and quality of the doors and windows. Utility Model Content

[0005] To address the limitations of existing technologies where the riveting device positions are fixed and cannot be flexibly adjusted for different profile sizes, thus failing to meet diverse processing needs; and even when attempting to adjust the positions of the two riveting devices, the lack of an effective synchronous adjustment mechanism and precise positioning reference makes it difficult to maintain ideal symmetry between the two sets of devices after adjustment, this invention provides an aluminum profile corner assembly machine. This machine allows for flexible adjustment of the positions of the two riveting devices, making it more suitable for corner assembly processing of profiles of different sizes and adaptable to diverse processing requirements. Furthermore, it enables synchronous and symmetrical adjustment of the two sets of riveting devices, ensuring symmetry during adjustment and thus guaranteeing the accuracy of subsequent riveting processing, ultimately ensuring the overall performance and quality of the assembled doors and windows. The specific technical solution is as follows:

[0006] An aluminum profile corner assembly machine includes a chassis, a worktable mounted on the chassis, a controller mounted on the side wall of the chassis, an mounting plate mounted on the rear side wall of the worktable, a cylinder mounted on the mounting plate, and a movable frame connected to the output end of the cylinder. The movable frame consists of a horizontal section and two sets of inclined sections, forming a frame with an open front side. A riveting device is fixedly mounted on the inclined section of the movable frame, and the two sets of riveting devices are arranged symmetrically about the horizontal section of the movable frame.

[0007] In the above technical solution, the two sets of riveting devices are adjusted and locked in position by adjusting components;

[0008] The adjustment assembly includes a first adjustment groove opened along the inclined portion of the movable frame. A movable seat is slidably embedded in the inner cavity of the first adjustment groove. A movable pin is fixedly installed at the top of the movable seat, and a drive frame is slidably sleeved on the movable pin.

[0009] In the above technical solution, the shape of the movable seat is set to n-shape.

[0010] In the above technical solution, the drive frame moves in the front-to-back direction via a drive assembly;

[0011] The drive assembly includes a fixed plate fixedly installed on the horizontal part of the movable frame. A first lead screw is threaded through the fixed plate and is rotatably connected to the rear side wall of the drive frame. A light rod is installed on the rear side wall of the drive frame and slides through the outer wall of the fixed plate.

[0012] In the above technical solution, a mounting frame is installed on the workbench, and a second adjustment groove is provided on the mounting frame. A bolt is slidably embedded in the inner cavity of the second adjustment groove. Two positioning nuts are threaded on the outer wall of the bolt. The two positioning nuts are respectively rotated to fit against the upper and lower side walls of the mounting frame. A first limiting seat is fixedly installed at the bottom end of the bolt. A limiting groove is provided on the front side wall of the first limiting seat.

[0013] In the above technical solution, the limiting groove is V-shaped.

[0014] In the above technical solution, the worktable is provided with a sliding groove from front to back, a second lead screw is rotatably connected in the sliding groove, a slider is threaded on the second lead screw, and a second limiting seat is fixedly installed at the top of the slider.

[0015] In the above technical solution, the rear end of the second limiting seat is triangular, and the triangular shape of the rear end of the second limiting seat is adapted to the shape and size of the limiting groove.

[0016] The advantages of this aluminum profile corner assembly machine compared with the prior art are as follows:

[0017] I. In view of the problem that the position of the punching and riveting device of the existing corner assembly machine is fixed and cannot be flexibly adjusted according to different sizes of profiles, and cannot adapt to diverse processing needs, this utility model can flexibly adjust the position of the two sets of punching and riveting devices, and is more suitable for corner assembly processing needs of different sizes of profiles, and can better adapt to diverse processing needs.

[0018] II. Regarding the problem that existing corner assembly machines cannot maintain an ideal symmetrical relationship between the two sets of punching and riveting devices after adjustment due to the lack of an effective synchronous adjustment mechanism and precise positioning reference, this utility model uses a cylinder and a moving frame to enable the two sets of punching and riveting devices to be adjusted synchronously and symmetrically. It can ensure the symmetry of the two sets of punching and riveting devices during the adjustment process, thereby ensuring the accuracy of subsequent punching and riveting processing and ensuring the overall performance and quality of the door and window corner assembly.

[0019] Third, by setting up a movable pin, a drive frame, a fixed plate, and a first lead screw, the position of the drive frame and two sets of movable pins can be adjusted, thereby causing the position of the two sets of riveting devices relative to the first adjustment groove to be adjusted, and the distance between the two sets of riveting devices and the limiting groove to be adjusted, so as to cause the two sets of riveting devices to perform riveting processing on the aluminum profile after corner assembly at different positions, so as to adjust the riveting position for aluminum profiles of different sizes.

[0020] IV. This utility model is provided with a mounting bracket, a second adjustment groove, bolts, positioning nuts, a first limiting seat, and a limiting groove, which can limit the rear side of the aluminum profile when assembling the corners. The second limiting seat can limit the front diagonal side of the aluminum profile when assembling the corners, that is, it can limit the front and rear directions of the aluminum profile when assembling the corners, ensuring the stability of the aluminum profile during the stamping and riveting process.

[0021] V. This utility model, through the sliding groove, the second lead screw, the slider, and the second limiting seat, can adjust the position of the second limiting seat relative to the limiting groove. After the aluminum profile is placed between the limiting groove and the second limiting seat, the aluminum profile is clamped by the movement of the second limiting seat closer to the limiting groove.

[0022] In summary, this utility model allows for flexible adjustment of the positions of the two sets of riveting devices, making it more suitable for corner assembly processing of profiles of different sizes and adaptable to diverse processing needs. Furthermore, it ensures the symmetry of the two sets of riveting devices during adjustment, thereby guaranteeing the accuracy of subsequent riveting processing and ensuring the overall performance and quality of the assembled doors and windows. Additionally, the distance between the two sets of riveting devices and the limiting groove can be adjusted to allow the two sets of riveting devices to perform riveting processing on the assembled aluminum profiles at different positions.

Detailed Implementation

[0028] The following are specific implementation cases and appendices. Figures 1 to 4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0029] See Figures 1 to 4 As shown, an aluminum profile processing corner assembly machine includes a housing 1, a worktable 2 mounted on the housing 1, a controller 3 mounted on the side wall of the housing 1, an mounting plate 4 mounted on the rear side wall of the worktable 2, a cylinder 5 mounted on the mounting plate 4, and a moving frame 6 connected to the output end of the cylinder 5. (See reference...) Figure 2 As shown, the movable frame 6 consists of a horizontal section and two sets of inclined sections. The horizontal section and the two sets of inclined sections form a frame with an open front. The inclined sections of the movable frame 6 are fixedly equipped with riveting devices 7. The two sets of riveting devices 7 are arranged symmetrically about the horizontal section of the movable frame 6. When the two sets of riveting devices 7 are brought close to the aluminum profile to be riveted, the movable frame 6 is driven to move forward by the activated cylinder 5, so as to drive the two sets of riveting devices 7 to move forward simultaneously, so as to bring the two sets of riveting devices 7 close to the aluminum profile simultaneously for riveting processing of the aluminum profile after riveting.

[0030] Main references Figures 2 to 4 As shown, the two sets of riveting devices 7 are positioned and locked by an adjustment assembly. The adjustment assembly includes a first adjustment groove 8 opened along the inclined part of the movable frame 6. A movable seat 9 is slidably embedded in the inner cavity of the first adjustment groove 8. A movable pin 10 is fixedly installed on the top of the movable seat 9. A drive frame 11 is slidably sleeved on the movable pin 10. The movement of the drive frame 11 causes the movable pin 10 to move synchronously along the inner cavity of the drive frame 11 and the inner cavity of the first adjustment groove 8, that is, the position of the movable seat 9 in the inner cavity of the first adjustment groove 8 is adjusted, so that the subsequent riveting position of the two sets of riveting devices 7 relative to the corner of the aluminum profile can be adjusted. The movable seat 9 is n-shaped, and can move along the first adjustment groove 8 and the outer wall of the riveting device 7 without leaving the inner cavity of the movable seat 9.

[0031] Main references Figure 2 and Figure 3 As shown, the drive frame 11 moves in the front-to-back direction via a drive assembly. The drive assembly includes a fixed plate 12 fixedly installed on the horizontal part of the movable frame 6. A first lead screw 13 is threaded through the fixed plate 12 and rotatably connected to the rear side wall of the drive frame 11. A guide rod 14 is installed on the rear side wall of the drive frame 11 and slides through the outer wall of the fixed plate 12. When adjusting the position of the two riveting devices 7 relative to the aluminum profile corner processing, the drive frame 11 moves in the front-to-back direction by driving the first lead screw 13 to rotate, so as to cause the guide rod 14 to move synchronously in the front-to-back direction along the fixed plate 12. At this time, the movement of the drive frame 11 causes the moving pin 10 to move synchronously along the inner cavity of the drive frame 11 and the inner cavity of the first adjustment groove 8, that is, to adjust the position of the moving seat 9 in the inner cavity of the first adjustment groove 8.

[0032] In addition, the main references Figure 1 and Figure 2As shown, a mounting bracket 15 is installed on the workbench 2. A second adjustment groove 16 is provided on the mounting bracket 15. A bolt 17 is slidably embedded in the inner cavity of the second adjustment groove 16. Two positioning nuts 18 are threaded on the outer wall of the bolt 17. The two positioning nuts 18 are rotated to fit against the upper and lower side walls of the mounting bracket 15. A first limiting seat 19 is fixedly installed at the bottom of the bolt 17. A limiting groove 20 is provided on the front side wall of the first limiting seat 19. The two sets of positioning nuts 18 are rotated to the position where they are disengaged from the outer wall of the mounting bracket 15. The bolt 17 is moved along the inner cavity of the second adjustment groove 16 to adjust the front and back direction of the limiting groove 20. After adjustment, the two sets of positioning nuts 18 are threaded onto the bolt 17 and made to fit against the upper and lower side walls of the mounting bracket 15. That is, the positioning and locking of the bolt 17 after it moves at the mounting bracket 15 is achieved by means of the two sets of positioning nuts 18, which ensures the stability of the position of the limiting groove 20 after adjustment.

[0033] To ensure that the limiting groove 20 can position the right angle of the aluminum profile, the limiting groove 20 is V-shaped. The worktable 2 has a sliding groove 21 from front to back. A second lead screw 22 is rotatably connected in the sliding groove 21. A slider 23 is threaded on the second lead screw 22. A second limiting seat 24 is fixedly installed at the top of the slider 23. The aluminum profiles to be processed are placed in the limiting groove 20 for docking. By driving the second lead screw 22 to rotate, the slider 23 moves along the inner cavity of the sliding groove 21, so that the second limiting seat 24 moves close to the limiting groove 20, and the aluminum profile between the second limiting seat 24 and the limiting groove 20 is positioned. Subsequently, the aluminum profiles after corner assembly are riveted by the opened riveting device 7.

[0034] In addition, the rear end of the second limiting seat 24 is triangular, and the shape and size of the triangular rear end of the second limiting seat 24 are adapted to the limiting groove 20, so as to ensure that the right angle after the aluminum profile is assembled can be fitted and limited at the triangular second limiting seat 24 and the limiting groove 20.

[0035] It is worth noting that in this application, the controller 3 is a commonly used controller for corner assembly machines in the market, capable of controlling the start and stop of various components and receiving and controlling commands in other situations; the cylinder 5 used is a commonly used self-locking cylinder in the market, whose output end can stop at any position and lock; the riveting device 7 is existing equipment, which is the same as the riveting device in the prior art with announcement number CN210817072U, and can meet the processing requirements for riveting aluminum profile corners, so its model and other details are not limited or described here; the first lead screw 13 and the second lead screw 22 are existing first lead screws 13 and second lead screws 22 that can achieve self-locking in the market, and can achieve self-locking when they stop rotating, and will not be affected by external forces to rotate; the model of the above-mentioned existing components is not limited or described in detail here.

[0036] The working principle of the aluminum profile corner assembly machine in this embodiment is as follows:

[0037] Pre-adjust the position of the limiting groove 20: Rotate the two sets of positioning nuts 18 to the position where they are disengaged from the outer wall of the mounting bracket 15, and move the bolt 17 along the inner cavity of the second adjustment groove 16 to adjust the front and back direction of the limiting groove 20. After adjustment, thread the two sets of positioning nuts 18 onto the bolt 17 and make the two sets of positioning nuts 18 fit against the upper and lower side walls of the mounting bracket 15 respectively. That is, the positioning and locking of the bolt 17 after it moves at the mounting bracket 15 is achieved by means of the two sets of positioning nuts 18, which ensures that the position of the limiting groove 20 is stable after adjustment.

[0038] When adjusting the position of the two riveting devices 7 relative to the aluminum profile corner during processing, the first lead screw 13 is driven to rotate, causing the drive frame 11 to move in the front-back direction, so as to cause the guide rod 14 to move synchronously in the front-back direction along the fixed plate 12. At this time, the movement of the drive frame 11 causes the moving pin 10 to move synchronously along the inner cavity of the drive frame 11 and the inner cavity of the first adjustment groove 8, that is, to adjust the position of the moving seat 9 in the inner cavity of the first adjustment groove 8, so as to realize the adjustment of the subsequent riveting position of the two riveting devices 7 relative to the aluminum profile corner.

[0039] When the two sets of riveting devices 7 approach the aluminum profile to be riveted, the moving frame 6 is driven to move forward by the activated cylinder 5, so as to drive the two sets of riveting devices 7 to move forward simultaneously, so as to make the two sets of riveting devices 7 approach the aluminum profile simultaneously to perform riveting processing on the aluminum profile after the corner is formed.

[0040] The aluminum profiles to be processed are placed in the limiting groove 20 for docking, and the second lead screw 22 is driven to rotate to drive the slider 23 to move along the inner cavity of the slide groove 21, so as to make the second limiting seat 24 approach the limiting groove 20 and position the aluminum profiles between the second limiting seat 24 and the limiting groove 20. Subsequently, the aluminum profiles after corner assembly are riveted by using the opened riveting device 7.

[0041] This utility model allows for flexible adjustment of the positions of the two sets of riveting devices 7, making it suitable for corner assembly processing of profiles of different sizes and adaptable to diverse processing needs. It also ensures the symmetry of the two sets of riveting devices 7 during adjustment, thereby guaranteeing the accuracy of subsequent riveting processing and ensuring the overall performance and quality of the assembled door and window profiles. Furthermore, the distance between the two sets of riveting devices 7 and the limiting groove 20 can be adjusted to allow the two sets of riveting devices 7 to perform riveting processing on the assembled aluminum profiles at different positions. Any modifications, equivalent substitutions, or improvements made should be included within the protection scope of this utility model.
