[0005] Therefore, the present invention proposes an automatic corner assembly device for doors and windows to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0046] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and other obvious variations can be conceived by those skilled in the art.

[0047] As Figures 2 to 5 shown, an automatic corner assembling device for doors and windows includes:

[0048] A base 1, on the top of which an inner positioning mechanism and an outer positioning mechanism are provided, and the inner positioning mechanism and the outer positioning mechanism are used to position the door and window frames;

[0049] Two rotating plates 5, which are rotatably connected in the base 1 with the vertex of the top angle of the door and window frame as the center of the circle;

[0050] A rotation driving assembly, which is used to drive the two rotating plates 5 to rotate so that the rotating plates 5 are parallel to the door and window frames;

[0051] Two notches 2, which are symmetrically opened at the top of the base 1;

[0052] Two track frames 6, which are respectively fixedly connected to the side walls of the rotating plates 5 corresponding to the positions of the two notches 2. Knife seats 7 are slidably connected to both track frames 6, and several impact knives 8 are fixedly connected to the side walls of the knife seats 7;

[0053] Two first cylinders 9, which are fixedly connected to the track frames 6, and the telescopic rods of the first cylinders 9 are fixedly connected to the knife seats 7;

[0054] Specifically, in the prior art, during the process of corner assembling of isosceles right triangle doors and windows or equilateral triangle doors and windows, since the angles of the corner codes built in the isosceles right triangle doors and windows or equilateral triangle doors and windows are different, it is easy to cause the problem that the left and right impact knives 8 are difficult to adapt to the corner codes. This technical solution can solve the above problems, and the specific operation is as follows:

[0055] First, place the triangular door and window to be corner assembled (such as an equilateral triangle door and window) on the base 1, and then position the triangular door and window through the inner positioning mechanism and the outer positioning mechanism. Then start the rotation driving mechanism, so that the two rotating plates 5 rotate respectively with the vertex of the top angle of the door and window frame as the center of the circle, so that the rotating plates 5 are parallel to the two frames of the triangular door and window;

[0056] Then start the two first cylinders 9, so that the telescopic rods of the first cylinders 9 respectively push the two knife seats 7, so that the two knife seats 7 move along the track frames 6, so that the impact knives 8 act on the corner codes inside the door and window, thus completing the corner assembling of one of the door and windows;

[0057] Since the three angles of the equilateral triangle door and window are the same, when assembling the remaining two corners, there is no need to adjust the angles of the rotating plates 5;

[0058] During the process of assembling the components of an isosceles right - angled triangle door or window, since the three angles of the isosceles right - angled triangle door or window are not the same, when assembling the remaining two angles, the angle of the rotating plate 5 needs to be adjusted, and then the above operation is performed to assemble the isosceles right - angled triangle door or window.

[0059] Since the tool holder 7 moves together with the rotating plate 5, and after the rotating plate 5 is adjusted, it will be parallel to the corresponding door or window frame, it is beneficial to make the impact knife 8 adapt to corner codes of different angles, and thus beneficial to improve the processing accuracy.

[0060] It should be noted that before adjusting the rotating plate 5 to adapt to the door or window frame, the two rotating plates 5 are rotated to the maximum angle first, so that the included angle between the two rotating plates 5 is greater than 90 degrees.

[0061] As a further implementation of the present invention, the rotation drive assembly includes:

[0062] Two second air cylinders 13, the two second air cylinders 13 are fixedly connected inside the machine base 1, and the end parts of the expansion rods of the two second air cylinders 13 are rotatably connected to the side wall of the rotating plate 5; by setting the second air cylinders 13, the rotational adjustment of the rotating plate 5 is realized.

[0063] As a further implementation of the present invention, two arc - shaped chutes 3 are symmetrically opened at the end of the machine base 1, and the arc - shaped chutes 3 are concentric with the vertex of the top angle of the door or window frame;

[0064] Two rotating brackets 10 are respectively slidably connected in the arc - shaped chutes 3, and the rotating brackets 10 are fixedly connected to the rotating plate 5 at the corresponding positions; by setting the rotating brackets 10, the rotating plate 5 is extended, which is beneficial to support long - sized doors and windows.

[0066] Contact sensors 11 are arranged on the side walls of both rotating brackets 10;

[0067] A controller 12, based on the contact signal of the contact sensor 11, closes the second air cylinder 13 to stop the sliding of the rotating bracket 10; by setting the contact sensor 11 and the controller 12, during the movement of the rotating plate 5, the rotating bracket 10 drives the contact sensor 11 to move synchronously until the contact sensor 11 contacts the door or window, at which time the contact sensor 11 generates a contact signal, and the controller 12 controls the second air cylinder 13 to close based on the contact signal, thereby realizing the precise adjustment of the rotating plate 5, which is beneficial to ensuring that the rotating plate 5 is parallel to the door or window frame, and thus beneficial to making the impact knife 8 adapt to corner codes of different angles and improving the processing accuracy.

[0068] As a further embodiment of the present invention, the inner positioning mechanism comprises:

[0069] A clearance chute 4 is provided on the machine base 1;

[0070] A third cylinder 14, the third cylinder 14 is fixedly connected in the machine base 1 at a position corresponding to the yielding groove;

[0071] A mounting plate 15, the mounting plate 15 is fixedly connected to the telescopic rod of the third cylinder 14, and the mounting plate 15 is slidably connected to the top end of the base 1;

[0072] A first self-locking motor 16, the first self-locking motor 16 is fixedly connected to the mounting plate 15, the output shaft of the first self-locking motor 16 is fixedly connected to a first mounting column 17, the first mounting column 17 is slidably connected in the yielding chute 4, and the outer side wall of the first mounting column 17 is fixedly connected to three trapezoidal positioning blocks 18 at different angles in an annular array;

[0073] It should be noted that the end angles of the three trapezoidal positioning blocks 18 are 90 degrees, 60 degrees and 45 degrees respectively;

[0074] Specifically, by providing the first mounting column 17 and three trapezoidal positioning blocks 18 with different angles, when it is necessary to assemble the equilateral triangle, the first self-locking motor 16 is first started to rotate the first mounting column 17, so that the 60-degree trapezoidal positioning block 18 is rotated to a specified position. Since the three angles of the equilateral triangle door and window are the same, there is no need to switch the trapezoidal positioning block 18 when assembling the remaining two angles.

[0075] When it is necessary to assemble the isosceles right triangle, first start the first self-locking motor 16 to rotate the first mounting column 17 so that the 90-degree trapezoidal positioning block 18 rotates to the specified position. After the assembling of the angle is completed, the first mounting column 17 is rotated again so that the 45-degree trapezoidal positioning block 18 rotates to the specified position. Then, the third cylinder 14 is used to move the trapezoidal positioning block 18 to limit the inner vertex of the triangular door and window.

[0076] As a further embodiment of the present invention, the external positioning mechanism comprises:

[0077] A second self-locking motor 19, the second self-locking motor 19 is fixedly connected to the top of the base 1, the output shaft of the second self-locking motor 19 is fixedly connected to a second mounting column 20, the second mounting column 20 is rotatably connected to the top surface of the base 1, and the outer wall of the second mounting column 20 is fixedly connected to three V-shaped positioning plates 21 at different angles in an annular array;

[0078] It should be noted that the groove angles at the ends of the three V-shaped positioning plates 21 are 90 degrees, 60 degrees and 45 degrees respectively;

[0079] Specifically, by setting the second self-locking motor 19 and the V-shaped positioning plate 21, when assembling the corners of an equilateral triangle, first start the first self-locking motor 16 and at the same time start the second self-locking motor 19, so that the second mounting post 20 rotates, and the 60-degree V-shaped positioning plate 21 rotates to the designated position. Since the three angles of an equilateral triangle door and window are the same, when assembling the remaining two corners, there is no need to switch the positioning block of the V-shaped positioning plate 21;

[0080] When assembling the corners of an isosceles right triangle, start the second self-locking motor 19, so that the second mounting post 20 rotates, and the 90-degree V-shaped positioning plate 21 rotates to the designated position. After completing the corner assembly, then rotate the second mounting post 20 so that the 45-degree trapezoidal positioning block 18 rotates to the designated position. Then, through the second self-locking motor 19, adjust the 45-degree V-shaped positioning plate 21 to rotate to the designated position. The outer vertices of the triangular door and window are limited by the 45-degree trapezoidal positioning block 18 and the 45-degree V-shaped positioning plate 21, thereby positioning the triangular door and window, which is beneficial to avoiding the position deviation of the door and window during the corner assembly process.

[0081] The working principle of the present invention: First, place the triangular door and window to be assembled (such as an equilateral triangle door and window) on the machine base 1, and then position the triangular door and window through the inner positioning mechanism and the outer positioning mechanism. Then start the rotation driving mechanism, so that the two rotating plates 5 rotate respectively with the vertex of the top angle of the door and window frame as the center of the circle, so that the rotating plates 5 are parallel to the two frames of the triangular door and window;

[0082] Then start the two first cylinders 9, so that the telescopic rods of the first cylinders 9 respectively push the two tool holders 7, so that the two tool holders 7 move along the track frame 6, so that the impact knives 8 act on the corner codes inside the door and window, thereby completing the corner assembly of one of the door and windows;

[0083] Since the three angles of an equilateral triangle door and window are the same, when assembling the remaining two corners, there is no need to adjust the angle of the rotating plate 5;

[0084] During the process of assembling an isosceles right triangle door and window, since the three angles of an isosceles right triangle door and window are not the same, when assembling the remaining two corners, it is necessary to adjust the angle of the rotating plate 5, and then perform the above operations to assemble the isosceles right triangle door and window;

[0085] Since the tool holder 7 moves together with the rotating plate 5, and the rotating plate 5 will be parallel to the corresponding frame after adjustment, it is beneficial to make the impact knife 8 adapt to corner codes of different angles, and thus beneficial to improving the processing accuracy.
