[0035] For examples, please refer to the attached Figure 1-7 A welding device for metal door and window processing includes a welding table 20, a first clamping mechanism 30 is installed on the top of the welding table 20, and a circular groove 22 is arranged on the welding table 20 on one side of the first clamping mechanism 30.

[0036] An angle adjustment mechanism 50 is provided in the circular groove 22 area, and the angle adjustment mechanism 50 includes a connecting shaft 51 rotatably connected to the center of the circular groove 22, a rotating table 52 installed on the connecting shaft 51, and a locking assembly arranged on one side of the rotating table 52 for fixing the position of the rotating table 52; a second clamping mechanism 40 is installed on the rotating table 52, and a welding mechanism 60 is installed in the side area of ​​the welding table 20.

[0037] It should be noted that the electrical components of this device are all externally powered and electrically connected to a conventional PLC controller.

[0038] For details, please refer to the attached Figure 3 The welding table 20 is provided with two sliding grooves 21 along the width direction, and a cavity is provided on one side of the two sliding grooves 21. The first clamping mechanism 30 includes a first fixed plate 31 installed on one side of the two sliding grooves 21, two ball screws 33 rotatably connected in the two sliding grooves 21, two nut seats 34 symmetrically installed on the two, a driving motor 35 connected to the ball screw 33, two first movable plates 32 installed on the two nut seats 34, two transmission wheels 36 rotatably connected inside the cavity and respectively connected to the two ball screws 33, and a transmission belt 37 sleeved on the two transmission wheels 36.

[0039] It should be noted that, in this embodiment, by operating the driving motor 35 and cooperating with the transmission of the two transmission wheels 36 and the transmission belt 37, the two ball screws 33 can rotate synchronously and in the same direction, so that the two nut seats 34 drive the two first movable plates 32 to move toward the first fixed plate 31, and then one of the metal rods is firmly clamped by the two first movable plates 32 and the first fixed plate 31, and the metal rod will serve as the fixed end.

[0040] For details, please refer to the attached Figure 6 The second clamping mechanism 40 includes a second fixed plate 43 and an electric push rod 41 installed on the rotating truncated table 52, and a second movable plate 42 installed at the output end of the electric push rod 41. The second fixed plate 43 and the electric push rod 41 are in a vertical state.

[0041] It should be noted that, in this embodiment, the second movable plate 42 can be moved toward the second fixed plate 43 through the operation of the electric push rod 41, so as to firmly clamp the metal rod. The metal rod serves as a rotating end and presents a required angle with the metal rod clamped by the first clamping mechanism 30, thereby completing the angle welding of doors and windows of different shapes.

[0042] For details, please refer to the attached Figure 6 Rubber pads 70 are installed on the side where the first fixed plate 31 and the two first movable plates 32 are close to each other, and on the side where the second fixed plate 43 and the second movable plate 42 are close to each other.

[0043] It should be noted that, in this embodiment, the rubber pad 70 can increase the friction resistance, thereby clamping the metal rod more firmly, preventing the metal rod from shifting during welding and affecting the welding effect.

[0044] For details, please refer to the attached Figure 5 An L-shaped groove 23 is provided on the welding table 20 on one side of the circular groove 22. The locking assembly of the angle adjustment mechanism 50 includes an L-shaped block 53 and a compression spring 55 installed in the L-shaped groove 23, and a positioning shaft 54 ​​installed on one side of the L-shaped block 53 and penetrating into the circular groove 22; a plurality of positioning grooves 521 adapted to the positioning shaft 54 ​​are provided on the side of the rotating circular table 52.

[0045] It should be noted that, in this embodiment, by fixing the positioning shaft 54 ​​in different positioning grooves 521, the rotating table 52 can be fixed at different angles, so that one of the metal rods is fixed in position after rotating a certain angle, which is convenient for subsequent angle welding.

[0046] For details, please refer to the attached Figure 6 The top side of the rotating table 52 in the top area of ​​the multiple positioning grooves 521 is provided with identification grooves 522.

[0047] It should be noted that, in the present embodiment, the identification groove 522 is engraved with numbers three, four, five, six, and eight, which correspond to different regular polygons respectively. When the positioning shaft 54 ​​is in different positioning grooves 521, the angles between the metal rod on the second clamping mechanism 40 and the metal rod on the first clamping mechanism 30 are 60°, 90°, 108°, 120°, and 135°, which correspond to the common inner angles of regular polygons respectively, so as to weld regular polygon doors and windows;

[0048] It should also be noted that the positioning grooves 521 can be increased according to actual needs.

[0049] For details, please refer to the attached Figure 5 One end of the top of the L-shaped block 53 does not exceed the top plane of the L-shaped groove 23, and a buckle groove 531 is provided on the top of the L-shaped block 53, and a handle 56 is installed on the rotating round table 52.

[0050] It should be noted that, in this embodiment, the L-shaped block 53 does not protrude, and thus does not affect the rotation of the metal rod on the rotating table 52. The buckle groove 531 facilitates the buckling of the L-shaped block 53 for displacement, and the handle 56 can be held by hand to facilitate the rotation of the rotating table 52.

[0051] For details, please refer to the attached Figure 2A support frame 10 is also installed on the outside of the welding table 20. The top area of ​​the support frame 10 is a U-shaped structure. Slide blocks 25 are provided on both sides of one end of the inner side of the welding table 20. A slide groove 11 is provided on the inner side of the welding table 20. The slide block 25 slides inside the slide groove 11. A handle 24 is installed at the center of the outer side of the welding table 20.

[0052] It should be noted that in this embodiment, when the metal rod needs to be clamped, in order to facilitate positioning, the welding table 20 can be pulled out through the handle 24 and then clamped and the angle adjusted. After the adjustment is completed, the welding table 20 is pushed into the support frame 10 to increase convenience.

[0053] For details, please refer to the attached Figure 7 The welding mechanism 60 includes a three-axis movable platform slide module 61 installed outside the support frame 10 and a welding gun 62 installed on a driving block of an X-axis module of the three-axis movable platform slide module 61 .

[0054] It should be noted that, in this embodiment, the three-axis mobile platform slide module 61 is a prior art and will not be overly introduced. The three-axis mobile platform slide module 61 can realize XYZ three-axis movement of the welding gun 62, thereby welding different positions of the metal rod.

[0055] The welding method used in any of the above-mentioned welding devices for metal door and window processing comprises the following steps:

[0056] Step 1: First, place one of the metal rods between the first fixed plate 31 and the two first movable plates 32, and start the driving motor 35 so that the first fixed plate 31 and the two first movable plates 32 fix the metal rod;

[0057] Step 2: Then, another metal rod is placed between the second fixed plate 43 and the second movable plate 42, and the electric push rod 41 is started so that the second fixed plate 43 and the second movable plate 42 fix the metal rod;

[0058] Step 3: Rotate the rotating table 52 according to the welding angle required for the two metal rods. Use one hand to push the L-shaped block 53 toward the end away from the rotating table 52 to pull the positioning shaft 54 ​​out of the positioning groove 521. Use the other hand to rotate the rotating table 52 to make the two metal rods present a suitable angle. When the two metal rods are rotated to a suitable angle, release the L-shaped block 53. The compression spring 55 pushes the L-shaped block 53 to insert the positioning shaft 54 ​​into the corresponding positioning groove 521 to complete the angle fixing of the rotating table 52.

[0059] Step 4: fine-tune the positions of the two metal rods through the first clamping mechanism 30 and the second clamping mechanism 40 so that the welding positions of the two are aligned, and finally start the welding mechanism 60 to perform welding.

[0060] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
