Description

Technical Field

[0001] This application relates to the field of door and window assembly technology, and in particular to an aluminum alloy door and window frame assembly and fastening device. Background Technology

[0002] The corner assembly of aluminum alloy door and window frames is a crucial step in ensuring the stability, sealing, and aesthetics of doors and windows. Its core involves precisely cutting, fixing with connectors, and sealing two profiles at the corner (usually 90°) to form a whole. The assembly components include aluminum alloy profiles, steel corner brackets, weather-resistant corner adhesive, compatible self-tapping screws, and sealing strips. The two profiles are connected by corner brackets and secured with a corner fastening device.

[0003] Existing corner fastening devices require adjusting the height of the two pressure blades according to different models of aluminum alloy door and window frames to form corner grooves of different heights on the profiles. However, when adjusting the height of the pressure blades, it is necessary to adjust the height of the pressure blades separately on the overall equipment. This process is time-consuming and labor-intensive. Moreover, the height of the two pressure blades must be measured manually with a tape measure, which affects both accuracy and efficiency. In addition, after fastening, the two pressure blades are not connected, resulting in poor stability and a risk of displacement, which may affect the corner fastening quality. Summary of the Invention

[0004] This device provides an assembly and fastening device for aluminum alloy door and window frames, and the specific implementation method is as follows:

[0005] An aluminum alloy door and window frame assembly and fastening device includes:

[0006] V-shaped positioning blocks are used to position one end of the assembled profile.

[0007] Fastening components are provided on both sides of the V-shaped positioning block. The fastening components include horizontal telescopic components and a sliding seat. The sliding seat integrates a pressure knife assembly. The horizontal telescopic components on both sides push the sliding seat with the pressure knife assembly horizontally out. The pressure knife assembly fastens and presses against the profile and generates a corner groove.

[0008] The pressing knife assembly includes an assembly block on which an upper pressing knife and a lower pressing knife are mounted. A spacing adjustment structure is provided between the upper pressing knife and the lower pressing knife. The assembly block is vertically slidably connected to the translation seat, and the two are locked together by positioning bolts, integrating both the upper and lower pressing knives on the assembly block to improve the overall stability of the pressing knife assembly on the profile after the knife spacing is adjusted.

[0009] Preferably, it also includes a worktable, with V-shaped positioning blocks and horizontal telescopic components all located on the top of the worktable.

[0010] Based on the above technical solutions, by integrating both the upper and lower pressure knives onto the assembly block, the distance between the upper and lower pressure knives is first adjusted, and then the height of the entire pressure knife assembly on the sliding seat is adjusted using positioning bolts. This achieves accurate adjustment of the knife spacing and also improves the stability of the pressure knife assembly installation. Fixing the corners of aluminum alloy doors and windows using horizontal telescopic components and the sliding seat is a conventional technical method in this field. The horizontal telescopic components are conventional cylinder or hydraulic cylinder structures. The two horizontal telescopic components can also be controlled by a single drive source through a linkage structure, that is, a single drive source controls the two horizontal telescopic components to move inward synchronously.

[0011] Preferably, it also includes a mounting bracket located above the V-shaped positioning block, the mounting bracket being equipped with a pneumatic pressure block, the pneumatic pressure block acting vertically downwards on the upper end of the assembled profile.

[0012] Preferably, the translation seat has a groove on one side facing the profile, a vertical guide rail on one side of the groove, and a corner limiting block on the other side; the assembly block is vertically slidably connected to the vertical guide rail and the corner limiting block on both sides, and a number of positioning bolts are evenly distributed along the height direction of the translation seat.

[0013] Based on the above technical solutions, the assembly block is designed with guide patterns that fit into the corner limiting block, the sliding seat groove, and the vertical guide rail. The patterns, the groove contour, and the guide rail structure form a corresponding matching relationship. Through the fitting constraint between the patterns and the guide rail, on the one hand, the lateral offset and shaking that may occur during vertical movement are eliminated, ensuring the accuracy of the movement trajectory; on the other hand, by increasing the contact guide area, the stress generated by the assembly block during movement is dispersed, effectively reducing frictional resistance and significantly improving the smoothness of operation during vertical adjustment.

[0014] Preferably, the assembly block has a first groove and a second groove arranged side by side and connected to each other; a lower pressure knife is installed at the bottom of the first groove by fastening bolts, a lifting block is vertically slidable in the first groove, an upper pressure knife is installed on the lifting block by fastening bolts, and a vertical drive structure acting on the lifting block is provided in the second groove.

[0015] Preferably, a screw and a turning rod are arranged side by side in the second groove, and the two are driven by a gear structure, with the screw vertically threaded to the lifting block.

[0016] Preferably, the outer side of the first groove is provided with vertical scale lines, which are used to mark the position of the lifting block.

[0017] Based on the above technical solution, the opening directions of the first and second grooves are opposite, thus preventing contamination of the screw and turning rod on the working surface; and the scale lines are hidden at the contact position between the assembly block and the corner limiting block. After the distance between the upper and lower pressure blades is adjusted, the scale lines are concealed during subsequent assembly. This design not only avoids the problem of scale lines being easily contaminated with oil, dust and other pollutants due to exposure during operation, but also reduces wear that may occur during long-term use, thereby maintaining the clarity and accuracy of the scale markings and extending their effective service life.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. This utility model integrates the upper and lower pressure blades onto the same assembly block. First, the distance between the two blades is precisely adjusted, and then the overall height of the pressure blade assembly on the translational base is calibrated using positioning bolts. This design not only ensures the accuracy of blade spacing adjustment but also significantly improves the installation stability of the pressure blade assembly.

[0020] 2. This utility model has a simple structure. Vertical guide rails and corner limiting blocks are arranged on both sides of the groove in the translation seat, which further improves the lateral stability of the assembly block after installation.

[0021] 3. In this utility model, a screw and a turning rod are arranged side by side in the second groove. The distance between the upper and lower pressing blades can be adjusted through this screw structure, while ensuring the overall stability after the distance is adjusted.

The profile 10 is assembled into a square frame structure. The V-shaped positioning block 6 is used to position one end of the assembled profile 10. The fastening components include a horizontal telescopic component 2 and a sliding seat 3. The sliding seat 3 integrates a pressure knife assembly 7. The horizontal telescopic components 2 on both sides push the sliding seat 3 with the pressure knife assembly 7 horizontally out. The pressure knife assembly 7 fastens and presses against the profile 10 and generates a corner groove 1001. In this structure, the V-shaped positioning block 6 and the horizontal telescopic component 2 are both located on the top of the workbench 1. The center of the square frame structure of the profile 10 is the manual operation position 1002 during assembly and fastening, which requires personnel to stabilize the profile 10 and switch between different corners.

[0040] The pressure knife assembly 7 includes an assembly block 701, on which an upper pressure knife 702 and a lower pressure knife 708 are mounted. A spacing adjustment structure is provided between the upper pressure knife 702 and the lower pressure knife 708. The assembly block 701 is vertically slidably connected to the translation seat 3, and the two are locked together by a positioning bolt 8.

[0041] The mounting bracket 4 is equipped with a pneumatic pressure block 5. The pneumatic pressure block 5 acts vertically downward on the upper end of the assembled profile 10. In this structure, before and after assembly and tightening, the pneumatic pressure block 5 presses vertically downward, acting on the diagonal joint of the two profiles 10 and flattening it.

[0042] The translation seat 3 has a groove on one side facing the profile 10. A vertical guide rail 301 is provided on one side of the groove, and a corner limiting block 302 is provided on the other side. In this structure, the assembly block 701 is vertically slidably connected to the vertical guide rail 301 and the corner limiting block 302 on both sides, and a number of positioning bolts 8 are evenly distributed along the height direction of the translation seat 3.

[0043] The specific implementation process is as follows: a person stands in the manual work position 1002 and abuts one corner of the square frame structure against the V-shaped positioning block 6. The pneumatic pressure block 5 presses down to initially flatten the joint vertically. The horizontal telescopic parts 2 on both sides push the pressure knife assembly 7 and the translation seat 3 inward, respectively acting on both sides of the square frame structure to press it tightly and generate the corner groove 1001.

[0044] Example 2

[0045] Reference Figures 1 to 7Based on the above embodiments, this embodiment also discloses an aluminum alloy door and window frame assembly and fastening device. The assembly block 701 is provided with a first groove 7011 and a second groove 7012 that are connected to each other. The bottom of the first groove 7011 is equipped with a lower pressure knife 708 by fastening bolts 709. A lifting block 704 is vertically slidably provided in the first groove 7011. An upper pressure knife 702 is installed on the lifting block 704 by fastening bolts 709. The second groove 7012 is provided with a vertical driving structure that acts on the lifting block 704.

[0046] The second groove 7012 has a screw 705 and a turning rod 707 arranged side by side, which are driven by a gear structure 706. The screw 705 is vertically threaded to the lifting block 704. In this structure, the outer side of the first groove 7011 is vertically provided with a scale line 703, which is used to mark the position of the lifting block 704.

[0047] The specific adjustment method is as follows: calculate in advance the height of the two corner grooves 1001 on the single profile 10, as well as the distance between the two corner grooves 1001; install the lower pressure knife 708 at the bottom of the first groove 7011 with the fastening bolt 709; rotate the screw rod 707 according to the scale line 703 to adjust the installation height of the lifting block 704 and the upper pressure knife 702 in the first groove 7011, thereby realizing the adjustment of the distance between the lower pressure knife 708 and the upper pressure knife 702; open the positioning bolt 8 and adjust the installation height of the assembly block 701 on the translation seat 3 so that the lower pressure knife 708 corresponds to the lower corner groove 1001 of the single profile 10, thereby realizing the adjustment of the overall corner height of the corner groove 1001.
