Detailed implementation manners

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0036] As Figures 1 - 11 shown, an assembly mechanism for an aluminum alloy door and window includes a base 1, and a screw fastening structure 3 is provided on the top of the base 1;

[0037] The screw fastening structure 3 includes a fixing frame 6 and a plurality of bases 23. A first bidirectional lead screw 7 is rotatably arranged inside the fixing frame 6, and one end of the first bidirectional lead screw 7 penetrates through the fixing frame 6 and is fixedly connected to the output shaft of a first motor 8.

A second electric push rod 21 is arranged on one side of the second fixing plate 20, and an installation plate 22 is fixedly arranged at one end of the second electric push rod 21. The base 23 is connected to the installation plate 22 through two first bolt fasteners 24, and a servo screwdriver 25 is arranged on one side of the base 23.

[0038] The screw fastening structure 3 can greatly improve the working adaptability of the splicing mechanism. The position of the servo screwdriver 25 can be adjusted according to the position of the threaded holes reserved in the aluminum alloy doors and windows, so that the servo screwdriver 25 can perform position translation or rotation, and can install screws or bolts in the threaded holes at the front and rear parts or both sides of the aluminum alloy doors and windows at one time, improving the splicing efficiency of the aluminum alloy doors and windows.

[0039] In this embodiment, a transmission mechanism 2 is arranged on the top of the base 1, and the fixing frame 6 is fixedly connected to the base 1.

[0040] The transmission mechanism 2 plays a role in transporting the aluminum alloy doors and windows.

[0041] In this embodiment, a fixing block 14 is fixedly arranged inside the first storage rack 11, and the second bidirectional lead screw 12 penetrates through the fixing block 14. A baffle 15 is fixedly arranged on the outer part of the fixing block 14, and two threaded holes are formed in the outer part of the baffle 15.

[0042] The baffle 15 and the screw fastening structure 3 can limit the positions of the front and rear parts of the aluminum alloy doors and windows. When the first slider 9 moves, the baffle 15 moves synchronously until it contacts the outer side of the aluminum alloy doors and windows and then stops for limiting and constraining, which is beneficial to correcting the position of the aluminum alloy doors and windows for the subsequent installation of screws or bolts.

[0043] In this embodiment, a plurality of threaded holes are formed in one side of the installation plate 22, and the threads of the first bolt fasteners 24 are thread-adaptively matched with the threaded holes of the installation plate 22.

[0044] According to the height spacing between the threaded holes opened in the aluminum alloy doors and windows, the position of the corresponding servo screw driver 25 can be adjusted through the bolt fastener 24 so that it matches the position of the threaded holes of the aluminum alloy doors and windows.

[0045] In this embodiment, a limit pressing structure 4 is provided on the top of the base 1. The limit pressing structure 4 includes two electric telescopic rods 26.

A mounting bracket 31 is fixedly arranged on the top of the slider 30, and a limiting plate 32 is fixedly arranged on the top of the mounting bracket 31.

[0046] The limit pressing structure 4 can limit the positions on both sides of the aluminum alloy doors and windows, cooperate with the baffle 15 to limit the four sides of the aluminum alloy, and at the same time can achieve the effect of lifting and supporting the aluminum alloy doors and windows, avoiding damage to the aluminum alloy doors and windows caused by the transmission mechanism 2 after being pressed.

[0047] In this embodiment, a base plate 33 and a motor 34 are arranged outside the mounting bracket 31. The output shaft of the motor 34 penetrates through the mounting bracket 31 and is fixedly provided with a first bevel gear 35, and the first bevel gear 35 is meshed with a second bevel gear 36. The second bevel gear 36 is rotatably connected to the base plate 33. An electric push rod 37 is arranged on the top of the second bevel gear 36, and a first pressing plate 38 is fixedly arranged at one end of the electric push rod 37.

[0048] Under the action of the motor 34, the first bevel gear 35 and the second bevel gear 36 can make the first pressing plate 38 rotate, which can prevent the first pressing plate 38 from lifting the aluminum alloy doors and windows when the electric telescopic rod 26 moves upward, affecting the subsequent fixed installation work.

[0049] In this embodiment, the mounting bracket 31 is C-shaped, and the first pressing plate 38 is U-shaped.

[0050] The mounting bracket 31 can support and lift the aluminum alloy doors and windows.

[0051] In this embodiment, an auxiliary structure 5 is arranged outside the baffle 15. The auxiliary structure 5 includes a mounting seat 39. The mounting seat 39 is connected to the baffle 15 through two bolt fasteners 40. A third fixing plate 41 is fixedly arranged on the top of the mounting seat 39. An electric telescopic rod 42 is arranged on the top of the third fixing plate 41, and one end of the electric telescopic rod 42 penetrates through the third fixing plate 41 and is fixedly connected to a second pressing plate 43.

[0052] The auxiliary structure 5 enables the second pressing plate 43 to press down on the top of the aluminum alloy door and window. The second pressing plate 43 cooperates with the first pressing plate 38 to press the aluminum alloy door and window, which is beneficial for fixing the aluminum alloy door and window and facilitating the subsequent installation of screws or bolts.

[0053] In this embodiment, the first fixing plate 18, the second fixing plate 20, and the third fixing plate 41 are all L-shaped, and the second pressing plate 43 is U-shaped.

[0054] The second pressing plate 43 presses down to restrict the top of the aluminum alloy door and window.

[0055] In this embodiment, the first bolt fastener 24 and the second bolt fastener 40 are both composed of a bolt and a nut.

[0056] The first bolt fastener 24 adjusts and fixes the position of the base 23, and the second bolt fastener 40 fixes the position of the mounting seat 39.

[0057] It should be noted that the present invention is an assembling mechanism for aluminum alloy doors and windows. Before use, place the device in the required place, and it can reach the operating conditions for work. Figure 1 This is the initial state of the assembling mechanism: the distances between the two first sliders 9, the two second sliders 16, and the two third sliders 30 are all in the maximum state.

Start the electric push rod three 37 to raise the pressing plate one 38 until it stops when the horizontal height of the pressing plate one 38 exceeds the top of the aluminum alloy door and window and the top of the limit plate 32. Start the motor five 34 to make the bevel gear one 35 drive the bevel gear two 36 to engage until the bevel gear two 36 rotates 180 degrees and then stops. Then, use the electric push rod three 37 to lower the pressing plate one 38 until its bottom touches the top of the aluminum alloy door and window and stops. At this time, the outside of the aluminum alloy door and window is restricted by two baffles 15 and two limit plates 32, and at the same time, the top of the aluminum alloy door and window is pressed by two pressing plates one 38 and two pressing plates two 43;

[0061] According to the positions of the threaded holes at the front and rear of the aluminum alloy door and window, adjust the positions of the two sliders two 16 through the motor two 13 until it stops when the servo screwdriver 25 matches the corresponding threaded hole positions.
