[0002] Aluminum materials need to go through multiple processes such as cold bending, sawing, drilling, assembly, and coloring to make products. During the cutting process, effective fixing is required to ensure the precise processing of aluminum materials and guarantee the cutting dimension accuracy and cut quality. Therefore, special fixing fixtures are needed to meet the processing requirements.

[0003] Existing fixtures for cutting aluminum profiles for doors and windows have limitations. Firstly, their simple structures typically only provide basic clamping, making it difficult to stably clamp aluminum profiles of varying sizes, thus limiting their application. Secondly, some cutting devices require an additional measuring tape to determine the cutting length when cutting aluminum alloy door and window frames, making the process cumbersome. Furthermore, some cutting processes rely on manual adjustment of the cutting machine angle to accommodate different cutting angles, posing significant safety hazards and potentially leading to hand injuries to operators. Therefore, we need to propose a fixture for cutting aluminum profiles for doors and windows. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a fixing fixture for cutting aluminum profiles for doors and windows, including a bracket 1 and a worktable 2. The worktable 2 is mounted on the upper side of the bracket 1, and a support frame 3 is fixed on the upper side of the worktable 2. Two sets of clamping components for fixing aluminum profiles of different sizes and shapes for doors and windows are slidably installed inside the worktable 2. The clamping components include a housing 5, which is vertically installed inside the worktable 2. A vertical baffle 6 is slidably installed inside the housing 5, and side baffles 7 are installed on both sides of the vertical baffle 6. The side baffles 7 are rotatably installed inside the housing 5. By setting the vertical baffle 6 and the side baffles 7, an adjustable three-sided clamping space is formed to fix the aluminum profile.

[0025] The clamping assembly also includes a movable block 8, and the worktable 2 has a movable groove inside that matches the movable block 8. The movable block 8 slides along the movable groove, thereby adjusting the longitudinal position of the entire clamping assembly within the worktable 2 to prevent clamping offset due to the aluminum material being too long or too short. The movable block 8 is fixedly installed on both sides of the housing 5, and multiple pin holes 9 are longitudinally opened on both side walls of the housing 5, with pins 10 passing through the interior of the pin holes 9.

[0026] Place the aluminum profile to be cut between the vertical baffle 6 and the side baffle 7. Push the vertical baffle 6 downwards along the inside of the housing 5 until the top of the vertical baffle 6 contacts the bottom of the aluminum profile, forming a vertical barrier. At the same time, the side baffle 7 rotates to both sides along the pivot point to adapt to the width of the aluminum profile, forming a horizontal barrier. After the vertical baffle 6 and the side baffle 7 are adjusted to fit the aluminum profile, select the corresponding height of the pin holes 9 on both sides of the housing 5 and insert the pins 10 through them. The positions of the two are locked by mechanical limit, preventing displacement due to vibration or the force of the cutting tool during the cutting process.

[0027] A limiting component for limiting the cutting of aluminum profiles for doors and windows is installed on one side of the workbench 2. The limiting component includes an outer square tube 11, which is installed on the outside of the workbench 2. A cylindrical hole 12 is provided on the side of the outer square tube 11 away from the workbench 2. A bolt 13 slides through the cylindrical hole 12. The diameter of the cylindrical hole 12 is slightly larger than the diameter of the bolt 13, so that the bolt 13 can pass through and be pressed against the inner square tube 15 by a nut 14. The threaded end of the bolt 13 is fitted with a nut 14. The limiting component also includes an inner square tube 15, which slides inside the outer square tube 11. The outer surface of the inner square tube 15 is provided with scale lines 16, and a limiting baffle 17 is installed at one end of the inner square tube 15. The outer square tube 11 is hollow inside and has a square cross-section, which matches the square cross-section of the inner square tube 15. This allows the inner square tube 15 to slide axially while restricting its rotation to prevent the limiting baffle 17 from tilting, thus ensuring positioning stability. The aluminum profile of the door and window is positioned by setting a limiting baffle 17; the inner square tube 15 is set and its extension length is adjusted by sliding inside the outer square tube 11. With the help of the scale line 16 on the outer surface, the distance between the limiting baffle 17 and the cutting blade can be precisely controlled, thereby realizing the preset cutting length of the aluminum profile of the door and window.

[0028] After the aluminum material to be cut is clamped, the operator adjusts the inner square tube 15 to the target length according to the scale line 16, and then locks it through the bolt 13 and nut 14 in the cylindrical hole 12. When tightening the nut 14, the end of the bolt 13 presses against the surface of the inner square tube 15, using friction to limit the sliding of the inner square tube 15 and ensure that the limit length does not deviate during the cutting process. When cutting aluminum materials of different lengths, the nut 14 is loosened in the opposite direction, and the inner square tube 15 can extend and retract freely. It can be quickly adjusted to the new target length with the help of the scale line 16 and then re-locked.

[0029] A cutting assembly for cutting aluminum profiles for doors and windows is installed on the upper side of the workbench 2;

[0030] The cutting assembly includes a first screw 18, which is rotatably mounted on the top of a support frame 3. A first servo motor 19 is mounted on the outside of the support frame 3. One end of the first screw 18 extends rotatably to the outside of the support frame 3 and connects to the power output end of the first servo motor 19. A sliding block 20 is threaded onto the surface of the first screw 18. A sliding groove adapted to the sliding block 20 is provided inside the support frame 3. By setting the sliding block 20 and the sliding groove, the movement trajectory of the sliding block 20 can be limited, while providing stable support for the connected components.

[0031] The cutting assembly also includes an electro-hydraulic rod 21, which drives the lower components to adjust their overall height. The electro-hydraulic rod 21 is mounted on the lower side of the sliding block 20. A mounting box 22 is fixed to the working end of the electro-hydraulic rod 21. A second screw 23 is installed inside the mounting box 22, and a second servo motor 25 is installed outside the mounting box 22. One end of the second screw 23 extends rotatably to the outside of the mounting box 22 and connects to the power output end of the second servo motor 25. A transmission block 26 is threaded onto the surface of the second screw 23. A transmission groove adapted to the transmission block 26 is formed on the inner wall of the mounting box 22.

[0032] The cutting assembly also includes an "L"-shaped fixing plate 27 and a connecting rod 28. The "L"-shaped fixing plate 27 is rotatably mounted on one side of the mounting box 22. A fixing block 29 is mounted on the outer side of the "L"-shaped fixing plate 27, and a cutting machine 30 is mounted on the inner side of the "L"-shaped fixing plate 27. One end of the connecting rod 28 is rotatably mounted on both sides of the transmission block 26, and the other end of the connecting rod 28 is rotatably connected to both sides of the fixing block 29. By setting the transmission block 26, the movement of the transmission block 26 will push or pull the "L"-shaped fixing plate 27 around the connection point of the mounting box 22 through the connecting rod 28, thereby driving the cutting machine 30 mounted on its inner side to change its angle to meet different cutting angle requirements.

[0033] After the limit baffle 17 is adjusted to the preset length, the first servo motor 19 is started. Its power output end drives the first screw 18 connected to it to rotate on the top of the support frame 3. This drives the sliding block 20 to move on the top, thereby driving the lower components to move synchronously, realizing the adjustment of the cutting position in the horizontal direction to align with the part of the aluminum material to be cut. After adjusting to the appropriate position, the electric hydraulic rod 21 is started. The working end of the electric hydraulic rod 21 drives the cutting machine 30 to cut the aluminum material. If it is necessary to adjust the cutting angle, the second servo motor 25 is started, driving the second screw 23 inside the mounting box 22 to rotate, thereby driving the transmission block 26 to move along the screw axis. When the transmission block 26 moves toward the second servo motor 25, the connecting rod 28 pulls the fixing block 29, causing the "L"-shaped fixing plate 27 to rotate inward, thereby driving the inner cutting machine 30 to adjust its angle; when the transmission block 26 moves away from the second servo motor 25, the connecting rod 28 pushes the fixing block 29, causing the "L"-shaped fixing plate 27 to rotate outward, similarly driving the cutting machine 30 to change its angle, ensuring that the cutting machine 30 performs cutting operations at the appropriate angle.
