[0043] There are two docking seats 2, and the two docking seats 2 are symmetrically fixed to the upper end of the frame 1. The two docking seats 2 are arranged in a V shape with an angle of ninety degrees, and a gap is left between the two ends of the V-shaped tip part formed by the two docking seats 2.

[0044] Among them, the auxiliary alignment mechanism 3 is installed on the docking seat 2, and is used to assist the alignment of door and window frames placed on the two docking seats 2. Specifically, the auxiliary alignment mechanism 3 includes a plurality of V-shaped alignment components, and the V-shaped alignment components are arranged from top to bottom along the inner surface of the docking seat 2. The V-shaped alignment components include two rotating arms 31, and the two rotating arms 31 form a V-shape. The ends of the two rotating arms 31 away from the tip of the V-shape are both rotatably installed on the docking seat 2 through a rotating shaft, and a torsion spring is installed between the docking seat 2.

[0045] Furthermore, the ends of the two rotating arms 31 close to the V-shaped tip are rotatably mounted with an alignment pulley 32, and a synchronization structure is installed between the two rotating arms 31 forming the V-shape, so that the two rotating arms 31 rotate synchronously in opposite directions at the same angle. More specifically, the synchronization structure is located on the side of the docking seat 2 away from the rotating arms 31, such as Figure 4 As shown, the synchronization structure includes a first transmission gear 33 and a second transmission gear 34. There are two first transmission gears 33, and the number of second transmission gears 34 is an even number. The two first transmission gears 33 are coaxially fixed to the two rotating shafts respectively. The multiple second transmission gears 34 are all arranged between the two first transmission gears 33 and rotatably installed on the docking seat 2. The multiple second transmission gears 34 are meshed with each other and with the first transmission gears 33.

[0046] The welding equipment can automatically align the welding bevels of two door and window frames by means of two V-shaped docking seats 2 arranged at an angle of ninety degrees and cooperating with two V-shaped rotating arms 31, wherein the end surfaces of the two docking seats 2 close to each other are movably mounted with multiple ball bearings 201, and the multiple ball bearings 201 are evenly distributed on the docking seats 2, thereby reducing the frictional resistance between the door and window frames; the alignment pulleys 32 rotatably mounted at the ends of the two rotating arms 31 close to the V-shaped tips are also used to reduce the frictional resistance between the door and window frames.

[0047] A fixed frame 4 is commonly installed at the upper ends of the two docking seats 2. The grinding drive mechanism 6 is installed at the middle part of the bottom end of the fixed frame 4 through the lifting drive device 5. The grinding disc 7 is installed at the output end of the grinding drive mechanism 6 and is located directly below the gap. Specifically, the grinding drive mechanism 6 includes a lifting seat 61 fixed on the output shaft of the lifting drive device 5, a mounting seat 62 fixed at the bottom end of the lifting seat 61, and a grinding drive assembly installed on the inner side of the lifting seat 61. The grinding disc 7 is slidably installed on the inner side of the mounting seat 62. The grinding drive assembly is connected to the grinding disc 7 to drive the grinding disc 7 to rotate. A gear ring 702 is integrally provided on the circumferential side of the grinding disc 7, and a limiting slide groove 6202 for sliding connection of the gear ring 702 is provided on the inner side of the mounting seat 62.

[0048] More specifically, the grinding drive assembly includes a gear 63 and a dual-axis motor 64. The dual-axis motor 64 is fixed on the inner side of the lifting seat 61. The gear 63 is coaxially fixed on the output shaft of the dual-axis motor 64. The mounting seat 62 is provided with a through hole 6201 for the gear 63 to pass through. A limiting slip ring 701 meshing with the gear 63 is provided on the circumference of the grinding disc 7. The dual-axis motor 64 drives the gear 63 to rotate, thereby driving the grinding disc 7 to rotate, and grinding the welding bevel of the door and window frames.

[0049] Among them, a first bevel gear 65 is coaxially fixed on the output shaft of the dual-axis motor 64, and a friction wheel 67 is rotatably installed on the side end of the lifting seat 61 close to the docking seat 2. A second bevel gear 66 is coaxially fixed to the friction wheel 67, and the second bevel gear 66 is meshed with the first bevel gear 65. During the grinding process, the cooperation between the second bevel gear 66 and the first bevel gear 65 is utilized to make the dual-axis motor 64 drive the friction wheel 67 to rotate at the same time, and the friction wheel 67 feeds the door and window frame toward the side close to the grinding disk 7, thereby improving the grinding effect.

[0050] Among them, in order to ensure stable grinding and welding operations, the auxiliary alignment mechanism 3 also includes an electric locking member 37, a transmission chain 36 and a transmission sprocket 35. The electric locking member 37 is fixed on the docking seat 2. A plurality of transmission sprockets 35 are provided. The plurality of transmission sprockets 35 are respectively coaxially fixed with one of the rotating shafts on the plurality of V-alignment components, and the plurality of transmission sprockets 35 are connected by a transmission chain 36. The output end of the electric locking member 37 is coaxially fixed with one of the transmission sprockets 35.

[0051] Based on the coordinated arrangement of the above electric locking member 37, the transmission chain 36 and the transmission sprocket 35, after the two door and window frames are initially aligned, the electric locking member 37 is used to lock the first transmission gear 33 to facilitate stable grinding; after the grinding is completed, the locking effect of the electric locking member 37 on the first transmission gear 33 is released, and the two door and window frames slide downward under their own gravity until the welding bevels of the two door and window frames are aligned and fit together, and then the electric locking member 37 is used again to lock the first transmission gear 33 to perform stable welding operations.

[0052] The electric locking member 37 may adopt any electric locking structure in the prior art that can achieve the above-mentioned locking effect.

[0053] A waste collection frame 9 is placed at the inner bottom end of the frame 1. The waste collection frame 9 is located directly below the grinding disc 7 and is used to centrally collect waste generated by grinding and welding operations. Steps 10 are installed on both side ends of the frame 1 at the docking seat 2 to facilitate staff to take and place door and window frames.

[0054] Working principle:

[0055] Initial alignment operation: the two door and window frames to be welded are respectively placed on the end faces of one side of the two docking seats 2 close to each other, and the two docking seats 2 arranged in a V shape with an angle of 90 degrees cooperate with the two V-shaped rotating arms 31, so that the two door and window frames slide downward to the welding bevel under the action of their own gravity to automatically align, and the welding bevels of the two door and window frames in the initial alignment state directly contact with the set grinding disc 7 (on the one hand, it is convenient for instant synchronous grinding, and on the other hand, it can effectively prevent the bottom tip of the welding bevel of the door and window frame from being deformed due to local collision), and at this time, the first transmission gear 33 is locked by the electric locking member 37;

[0056] Grinding operation: Then, the double-axis motor 64 drives the gear 63 to rotate and drives the grinding disc 7 to grind the welding bevel of the door and window frame. In the grinding process, the second bevel gear 66 and the first bevel gear 65 cooperate to make the double-axis motor 64 drive the friction wheel 67 to rotate at the same time. The friction wheel 67 feeds the door and window frame toward the side close to the grinding disc 7, thereby improving the grinding effect and making the welding bevel of the door and window frame smoother, thereby improving the welding quality.

[0057] Align again: After the grinding is finished, the grinding disc 7 is evacuated upward by the lifting drive device 5, and the locking effect of the electric locking member 37 on the first transmission gear 33 is released. The two door and window frames slide downward under their own gravity until the welding inclined surfaces of the two door and window frames are aligned and attached (here the welding robot 8 can be used to limit the bottom of the door and window frames), and the electric locking member 37 is used to lock the first transmission gear 33 again;

[0058] Welding operation: Then the welding robot 8 can be used for welding. The coordinated design of the above structure makes the grinding and welding operations more coherent, greatly improving the welding quality and welding efficiency.

[0059] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
