[0053] The adjusting limit mechanism 3 includes a first motor 301, the output end of the first motor 301 is fixedly connected to the bottom plate 302, the inside of the bottom plate 302 is connected to the limit component 3001 by opening a slide slot, the limit component 3001 includes a limit block 303, the limit block 303 is connected to the bottom plate 302, the limit block 303 is fixedly connected to the first electromagnet 304, the outer surface of the first electromagnet 304 is in contact with the outer surface of the round tube support frame 1, the limit block 3 03 is fixedly connected to the outer surface of the first elastic band 305, and the interior of the bottom plate 302 is clamped with an adjustment component 3002 by opening a sliding groove, and the adjustment component 3002 includes a first clamping block 306, and the first clamping block 306 is slidingly connected to the bottom plate 302, and the first clamping block 306 is internally rotatably connected to the first screw rod 307, and the outer surface of the first clamping block 306 is fixedly connected to the bellows 308, and the first motor 301 is used to rotate the circular tube support frame 1, the support beam 2 and the support plate 4.

[0054] The adjustment and limiting mechanism 3 also includes an arc-shaped rubber plate 309, the outer surface of which is clamped with a second clamping block 310, the bottom of the second clamping block 310 is fixedly connected with a first connecting rod 311, and the outer surface of the first connecting rod 311 is fixedly connected with a first connecting plate 312 and a second connecting plate 313, and the arc-shaped rubber plate 309 is used to limit the circular tube support frames 1 of different sizes.

[0055] The limiting assembly 3001 and the adjusting assembly 3002 are symmetrically arranged in two groups on the outer surface of the bottom plate 302. The first screw 307 is threadedly connected to the first connecting plate 312 and the second connecting plate 313. The bellows 308 is concentric with the first screw 307. The bellows 308 is used to protect the first screw 307. By setting the adjusting limiting mechanism 3, the limiting block 303 and the first elastic band 305 can be adapted to weld frames of different planes and round tube sizes, thereby reducing auxiliary time and improving welding continuity and efficiency; and the first motor 301 can be used to rotate the unit frame, which greatly facilitates the operation of welding personnel, reduces the labor intensity of personnel, and helps to improve the stability of welding quality and production efficiency. When the round tube support frame 1 is placed on the upper surface of the limiting block 303, it is necessary to pull the symmetrically arranged limiting block 303 outward so that it does not affect the placement of the round tube support frame 1. The single side of the limiting block 303 enables it to adapt to round tube support frames 1 of different round tube sizes.

[0056] The working principle of this embodiment is as follows: when using the welding equipment and method for the frame of the automobile generator, the round tube support frame 1 is placed on the limit block 303, and is magnetically attracted by the first electromagnet 304. At the same time, the first elastic band 305 is retracted inward, pulling the limit block 303 to move along the slot of the bottom plate 302, and cooperates with the symmetrically arranged limit blocks 303 to limit the horizontal direction of the round tube support frame 1. After completing the horizontal limit, the arc rubber plate 309 is brought into contact with the outer surface of the round tube support frame 1, and the first screw 307 is started to rotate. The first screw 307 drives the first connecting plate 312 and the second connecting plate 313 to move downward, and The first connecting rod 311 is driven to move downward, and the second clamping block 310 is driven to move downward, and the arc rubber plate 309 is driven to move downward, so that it can vertically limit the circular tube support frame 1, and the welding of circular tube support frames 1 and support beams 2 of different sizes is realized through the horizontal movement of the limit block 303 and the up and down movement of the arc rubber plate 309. At this time, the operator welds the support beam 2 and the circular tube support frame 1. While completing the single-point welding, the first motor 301 rotates, driving the adjustment limit mechanism 3, the circular tube support frame 1 and the support beam 2 to rotate at the same time, so that it can weld to another position, and the welding of the support plate 4 repeats the steps to complete the welding.

[0057] Embodiment 2: Please refer to Figures 6 to 8. Based on the embodiment 1, the present invention provides a technical solution: the following adjustment mechanism 5 includes a following device 501, the following device 501 is fixedly connected to the lower surface of the first motor 301, the following device 501 is internally clamped with a third clamping block 502, the top of the third clamping block 502 is fixedly connected with a shell 503, the inside of the shell 503 is rotatably connected with a second screw rod 504, the outer surface of the second screw rod 504 is threadedly connected with a first slider 505, and the inside of the first slider 505 is slidably connected with a through hole. The first sliding rod 506 and the outer surface of the first sliding block 505 are fixedly connected to the first hydraulic pump 507, the outer surface of the first sliding rod 506 is hingedly connected to the arc column 508, the interior of the arc column 508 is rotatably connected to the rotating shaft ring 509 through a slot, the interior of the arc column 508 is fixedly connected to the annular electromagnet 510, the interior of the arc column 508 is slidably connected to the friction plate 511, the outer surface of the rotating shaft ring 509 is fixedly connected to the welding gun 512, and the second screw 504 is used to adjust the vertical position of the welding gun 512.

[0058] The third block 502 is rotated by the motor and gear inside the following device 501, and the output end of the first hydraulic pump 507 is fixedly connected to the outer surface of the first sliding rod 506 through the connecting plate. The first hydraulic pump 507 is symmetrically arranged to adjust the horizontal position of the welding gun 512. By setting the following adjustment mechanism 5, the welding of the unit frame of different sizes is adapted through the second screw 504; and the welding gun 512 is synchronously followed and moved by the following device 501, and the welding gun 512 is maintained in the relative position of the best welding through the multi-angle adjustment capability, so as to improve the welding accuracy and operation efficiency, reduce manual errors and instability, and by the rotation of the second screw 504, the following adjustment mechanism 5 is moved as a whole to the position of the lower surface of the bottom plate 302, so that it does not affect the rotation of the round tube support frame 1 driven by the first motor 301. The normal position of the first hydraulic pump 507 makes the arc column 508 contact the outer surface of the first slider 505, and the center of gravity of the welding gun 512 is the same as the center of gravity of the rotating shaft ring 509, so that it will not rotate due to gravity.

[0059] The working principle of this embodiment is as follows: when the frame welding equipment and welding method for the automobile generator are used, the second screw rod 504 rotates, driving the first slider 505 to move upward, so that the welding gun 512 is flush with the welding position. At this time, the first hydraulic pump 507 is retracted, and the first sliding rod 506 is pushed inward through the connecting plate, and the welding gun 512 and the mechanism are driven to move inward as a whole, so that the welding gun 512 contacts the welding position, and welding is performed. At the same time as welding, the first motor 301 starts to rotate, so that the round tube support frame 1 rotates, and the following The device 501 drives the welding gun 512 to rotate concentrically with the round tube support frame 1, and cooperate with each other to perform welding. When welding is required at a position that is difficult to weld, the horizontal rotation of the welding gun 512 is achieved by the difference in the telescopic distance of the symmetrically arranged first hydraulic pump 507. After the welding gun 512 contacts the welding position, the annular electromagnet 510 reduces the magnetism, so that the welding gun 512 can rotate around the shaft of the shaft collar 509. At the same time, by adjusting the second screw 504, the welding gun 512 can adapt to the angle of the position that is difficult to weld and perform welding.
