[0026] The utility model provides a technical scheme:

[0027] Please refer to Figures 1 to 3 Aluminum door and window corner assembling machine, including workbench 1, workbench 1 is provided with positioning mechanism 2, the top of positioning mechanism 2 is provided with pressing mechanism 3, the lower left corner of workbench 1 is fixedly installed with PLC controller 4.

[0028] Positioning mechanism 2 includes top corner fixer 21 and inner angle positioning assembly 22.

[0029] The inner corner positioning assembly 22 comprises a base block 221, a hydraulic rod 222 fixedly installed on the base block 221, an inner corner fixer 223 fixedly installed at the output end of the hydraulic rod 222 and matched with the top corner fixer 21, an installation slot 224 symmetrically opened in the inner corner fixer 223, a pressure sensor 225 fixedly installed at the middle section of the inner cavity bottom of the installation slot 224, a plurality of rubber air bags 226 fixedly installed on the pressure sensor 225, the rubber air bags 226 being stacked, a movable plate 227 fixedly installed on the rubber air bags 226 and matched with the installation slot 224, and telescopic springs 228 fixedly installed at both ends of the inner cavity bottom of the installation slot 224 and fixedly connected with the movable plate 227. The inner corner positioning assembly 22 is pushed by the hydraulic rod 222 fixedly installed on the base block 221 to make the inner corner fixer 223 accurately extend and retract, so that the inner corner fixer 223 gradually fits the inner top corner formed by the two profiles. The installation slot 224 in the inner corner fixer 223 is provided with the pressure sensor 225 and the stacked rubber air bags 226. When the profile contacts the movable plate 227, with the increase of the pressure, the movable plate 227 drives the rubber air bags 226 to move inward and compress the telescopic springs 228, and at the same time, the pressure sensor 225 monitors the pressure change in real time, so as to ensure stable fixation and avoid excessive compression. This process improves the accuracy and stability of profile processing and effectively reduces assembly errors.

[0030] Further, the top corner fixer 21 is fixedly connected with the workbench 1, wherein the included angle of the top corner fixer 21 towards the inner corner fixer 223 is 90 degrees. The top corner fixer 21 is fixedly connected with the workbench 1 during the working process, and the included angle of the top corner fixer 21 towards the inner corner fixer 223 is accurately designed as 90 degrees. This design ensures that after the two profiles are placed on the workbench and preliminarily positioned, the top corner fixer 21 can accurately clamp one outer corner of the profile, ensuring that the angle of the outer corner is 90 degrees. This step is the basis of profile corner assembly processing, providing a stable reference for subsequent inner corner fixation and compression operation, thereby improving the accuracy and efficiency of the entire processing process and ensuring the assembly quality and stability of aluminum door and window products.

[0031] Further, the movable plate 227 is higher than the surface of the inner corner fixer 223 where the movable plate 227 is located, wherein the movable plate 227 is parallel to the surface of the inner corner fixer 223 where the movable plate 227 is located. The movable plate 227 is designed to be higher than the surface of the inner corner fixer 223 where the movable plate 227 is located and remains parallel to the surface of the inner corner fixer 223. When the profile is pushed into the predetermined position and contacts the movable plate 227, with the continuous pushing of the hydraulic rod 222, the movable plate 227 can stably receive gradually increasing pressure and move inward. This process helps to accurately position the profile. This design of the movable plate 227 not only ensures the preliminary fixation of the inner corner of the profile, but also provides a stable support surface for subsequent compression operation, thereby enhancing the stability of the profile during the processing process, avoiding position deviation and ensuring the processing accuracy of aluminum door and window corner assembly.

[0032] Further, the pressing mechanism 3 comprises a mounting plate 31 symmetrically mounted on the top of the workbench 1, the inner side of the mounting plate 31 is rotationally connected with a screw rod 32, the end of the screw rod 32 away from the mounting plate 31 is fixedly installed with a double-shaft motor 33, the output end of the double-shaft motor 33 is fixedly connected with the screw rod 32 and fixedly connected with the workbench 1, the double-shaft motor 33 drives the screw rod 32 to rotate after being started, since the screw rod 32 is threadedly connected with a ball screw block 34 and the outer side of the ball screw block 34 is fixedly installed with a linkage rod 35, the rotation of the screw rod 32 is converted into the linear motion of the ball screw block 34 and the linkage rod 35, thereby driving the pressing piece 36 to approach the profile for pressing and cutting operation. The function is to drive the pressing piece 36 to realize the connection of the aluminum door and window corner part, and the assembly precision and finished product quality of the aluminum door and window are improved by accurately controlling the pressing process.

[0033] Further, the outer side of the screw rod 32 is threadedly connected with the ball screw block 34, the outer side of the ball screw block 34 is fixedly installed with the linkage rod 35, the linkage rod 35 is slidingly connected with a limiting rod penetrating through the linkage rod 35, wherein the limiting rod is fixedly installed on the inner side of the mounting plate 31, the inner side of the linkage rod 35 is fixedly installed with the pressing piece 36, the pressing piece 36 is composed of a corner assembling cutter rod and a corner cutter, when the screw rod 32 rotates, the ball screw block 34 threadedly connected with the screw rod 32 moves linearly, the linkage rod 35 fixedly installed on the outer side of the ball screw block 34 moves, the linkage rod 35 stably slides under the guidance of the limiting rod, thereby driving the pressing piece 36 (composed of the corner assembling cutter rod and the corner cutter) fixedly installed on the inner side to approach the profile. The function of this process is to convert the rotary motion into linear motion through the threaded cooperation of the ball screw block 34 and the screw rod 32, the limiting rod makes the ball screw block 34 move on the screw rod 32 more stably, the position of the pressing piece is accurately controlled, the profile is pressed and cut, the accurate connection of the aluminum door and window corner part is ensured, and the assembly precision and finished product quality are improved.

[0034] Further, the PLC controller 4 is electrically connected with the pressure sensor 225, so that the PLC controller can receive the pressure data of the pressure sensor 225.

[0035] In specific use, the working principle of the utility model is as follows:

[0036] Before work starts, first, the aluminum alloy profile to be corner assembled is accurately placed on the positioning mechanism 2. The core components of the positioning mechanism include a top corner fixer 21 and an inner corner positioning assembly 22, which work cooperatively to ensure the accurate positioning of the profile.

[0037] The top corner fixer 21 is fixedly connected with the workbench 1, and is designed to preliminarily position the outer corner formed by the two profiles, ensuring that the included angle between them is 90 degrees. The inner corner positioning assembly 22 flexibly pushes the inner corner fixer 223 close to and gradually fits the inner top corner formed by the two profiles through the precise extension of the hydraulic rod 222, thereby firmly fixing the inner corner of the profile. This double fixation of the inner and outer corners greatly improves the stability of the profile during processing, avoiding assembly errors caused by positional deviation.

[0038] Particularly noteworthy is that the installation grooves 224 are symmetrically opened in the inner corner fixer 223. These installation grooves 224 not only have pressure sensors 225 fixedly installed therein, but also have several rubber airbags 226 ingeniously stacked therein. When the profile is pushed into the predetermined position and contacts the movable plate 227, the movable plate 227 will be subjected to gradually increasing pressure and move inward as the hydraulic rod 222 continues to push. This movement process not only compresses the rubber airbags 226 and the extension springs 228, but also monitors the pressure change of the movable plate in real time through the pressure sensor 225.

[0039] When the movable plate 227 finally levels with the surface of the inner corner fixer 223, the pressure data tends to be stable, indicating that the profile has been positioned. At this time, the pressure sensor 225 will transmit the monitored pressure signal to the PLC controller 4 in real time. The PLC controller can intelligently judge according to the received signal. Since the two sides of the inner corner fixer 223 can be subjected to extrusion by the profile, the pressure sensors 225 on both sides will transmit the pressure data monitored by themselves to the PLC controller.

[0040] The operator can intuitively compare the pressure data of the two sides of the inner corner fixer 223 through the interface displayed by the PLC controller 4. If the pressure data of the two sides is equal or very close, it can be judged that the profile has been accurately placed in the specified position, and the two profiles remain perpendicular. Conversely, if there is a significant difference in the pressure data of the two sides, it means that the position of the profile may be deviated or inclined, and timely adjustment is needed to ensure the processing precision and product quality in the subsequent process.

[0041] After positioning, the pressing mechanism 3 starts to work. After the double-shaft motor 33 is started, it drives the screw rod 32 to rotate. Since the screw rod 32 is threadedly connected with the ball screw block 34, the rotation of the screw rod 32 will be converted into the linear motion of the ball screw block 34. The linkage rod 35 fixedly installed on the outside of the ball screw block 34 will also move, thereby driving the pressing piece 36 to approach the profile. The pressing piece 36 is composed of a corner assembling knife rod and a corner assembling knife, which will perform pressing and cutting operations on the profile when they contact the profile, realizing the connection of the corner part.

[0042] In summary, the aluminum door and window corner assembling machine realizes high-precision positioning and real-time monitoring of the aluminum alloy profile through the positioning mechanism 2 and the intelligent monitoring system.

[0043] The above is only a specific embodiment of the present application, but the technical features of the present application are not limited thereto. Any simple change, equivalent replacement or modification made on the basis of the present application to solve the same technical problem and achieve the same technical effect is included in the protection scope of the present application.
