[0021] This invention provides the following technical solutions: Example 1

[0022] Please see Figure 1 - Figure 8 A welding device for building construction includes a base plate 1 and a pipe fitting 12. A fixing block 3 is fixedly connected to the upper side of the base plate 1, and a fixing ring 5 is fixedly connected to the outer side of the fixing block 3.

The installation unit 2 includes a guide plate 21, and a guide block 22 is slidably connected to the outer side of the guide plate 21. The upper side of the guide block 22... A movable plate 23 is fixedly connected, and an mounting plate 26 is fixedly connected to the upper side of the movable plate 23. A stabilizing component 27 is provided on the upper side of the mounting plate 26. The stabilizing component 27 is used to limit the two ends of the pipe fitting 12. A base block 24 is fixedly connected to the lower side of the movable plate 23.

A motor 4 for driving the rotating shaft 8 to rotate is fixedly connected to the right side of the fixed block 3.

[0023] When welding the pipe fitting 12, first place the two pipe fittings 12 on the mounting units 2 on both sides and limit their positions. Then, control the electric push rod 25 to move the base block 24, the base block 24 to move the moving plate 23, the moving plate 23 to move the mounting plate 26, the mounting plate 26 to move the fixing box 271, and the fixing box 271 to move the pipe fitting 12 so that the pipe fittings 12 on both sides come into contact. Then start the motor 4, the motor 4 to drive the rotating shaft 8 to rotate, the rotating shaft 8 to drive the gear 9 to rotate, the gear 9 to drive the gear ring 6 to rotate, and the gear ring 6 to drive the welding gun 7 to rotate, so that the welding gun 7 can weld the connection between the two pipe fittings 12.

[0024] The stabilizing component 27 includes a fixing box 271, which is fixedly connected to the upper side of the mounting plate 26. Two sliding holes 273 are formed on the upper side of the fixing box 271. Two sliders 274 are slidably connected to the inner side of the sliding holes 273. Control plates 275 are fixedly connected to the upper side of each slider 274. A groove 276 is formed on the upper side of the control plate 275. Two sliders 279 are slidably connected to the inner side of the groove 276. Two top blocks 2710 are fixedly connected to the upper side of each slider 279. A control rod 2711 is rotatably connected between the two top blocks 2710. A rotating block 2712 is fixedly connected to the middle of the control rod 2711. Clamping plates 2713 are fixedly connected to the outer sides of the rotating blocks 2712 on both sides. A support block 272 is fixedly connected to the middle of the upper side of the fixing box 271. The inner side of the fixing box 271 rotates... A rotating rod 2723 is connected to the upper end of the rotating rod 2723. A rotating plate 2724 is fixedly connected to the upper side of the rotating plate 2724. Two inclined plates 2725 are rotatably connected to the upper side of the rotating plate 2724. A control plate 2722 is fixedly connected to the lower side of the slider 274. The inclined plates 2725 are rotatably connected to the control plate 2722. A linkage plate 2726 is fixedly connected to the outer side of the rotating rod 2723. An inclined plate 2727 is rotatably connected to the outer side of the linkage plate 2726. A limit rod 2729 is fixedly connected to the inner side of the fixed box 271. A guide block 2728 is slidably connected to the outer side of the limit rod 2729. The guide block 2728 is rotatably connected to the inclined plate 2727. A side block 2730 is fixedly connected to the outer side of the guide block 2728. An electric push rod 2731 that drives the side block 2730 to move is fixedly connected to the inner side of the fixed box 271. Before welding the pipe fitting 12, first place the pipe fitting 12 on the support block 272. Then, control the electric push rod 2731 to drive the guide block 2728 to move. The guide block 2728 drives the inclined plate 2727 to rotate. The inclined plate 2727 drives the linkage plate 2726 to rotate. The linkage plate 2726 drives the rotating rod 2723 to rotate. The rotating rod 2723 drives the rotating plate 2724 to rotate. The rotating plate 2724 drives the inclined plate 2725 to rotate. The inclined plate 2725... The second control plate 2722 moves. Since the two inclined plates 2725 on both sides are arranged in parallel, the two control plates 2722 on both sides move away from each other. The second control plate 2722 drives the first slider 274 to move. The first slider 274 drives the first control plate 275 to move. The first control plate 275 drives the clamping plate 2713 to move. The two clamping plates 2713 on both sides move away from each other, which makes it convenient for the clamping plates 2713 on both sides to limit the two ends of the pipe fitting 12 and increase the stability of the pipe fitting 12 during welding.

[0025] Connecting block 2714 is fixedly connected to the outer side of slider 279 on both the front and rear sides. Inclined plate 2715 is rotatably connected to the outer side of connecting block 2714. Connecting block 2716 is rotatably connected to the outer side of inclined plate 2715. Push plate 2717 is fixedly connected to the outer side of connecting block 2716. Slide rod 2718 is fixedly connected to both the left and right sides of support block 272. Spring 2719 is fixedly connected between push plate 2717 and support block 272. A stop rod 2720 is fixedly connected to the outer side of push plate 2717. Contact block 2721 is fixedly connected to the upper side of fixed box 271. Slide rod 2718 is slidably connected to push plate 2717. Inclined plate 2715 on both the front and rear sides is symmetrically distributed. Contact block 2721 and stop rod 2720 are not connected. Clamping plate 2713 is set with an arc structure.

[0026] When the control plate 275 moves, it drives the push plate 2717 to move, and the push plate 2717 drives the abutment 2720 to move. When the abutment 2720 contacts the contact block 2721, the control plate 275 continues to move, so that the abutment 2720 moves in the opposite direction to the control plate 275. The abutment 2720 drives the push plate 2717 to move, and the push plate 2717 drives the inclined plate 2715 to rotate. The inclined plate 2715 drives the slider 279 to move. Since the inclined plates 2715 on both sides are symmetrically distributed, the sliders 279 on both sides move closer to the pipe 12, which facilitates the clamping plates 2713 on the front and rear sides to clamp and limit the pipe 12. This makes it easier for both ends of the pipe 12 to be limited at the same time, which facilitates the welding of the pipe 12.

[0027] Gear 2743 is fixedly connected to the outer end of control rod 2711. Side plate 277 is fixedly connected to the outer side of control plate 275. Toothed plate 278, which meshes with gear 2743, is fixedly connected to the outer side of side plate 277. After welding, push plate 2717 is reset under the action of spring 2719, controlling slider 279 to move. Slider 279 drives control rod 2711 to move. Control rod 2711 drives gear 2743 to move. Under the action of toothed plate 278, gear 2743 rotates. Gear 2743 drives control rod 2711 to rotate. Control rod 2711 drives rotating block 2712 to rotate. Rotating block 2712 drives clamping plate 2713 to rotate, so that clamping plates 2713 on the front and rear sides are placed parallel to control plate 275. This makes it easier for workers to directly place pipe fitting 12 during the next welding. Compared with the method of placing pipe fitting 12 axially (pipe fitting 12 is sleeved on limiting component), it is simpler. Example 2

[0028] Based on Example 1, such as Figure 9 , Figure 10As shown, a second side block 2737 is fixedly connected to the outer side of the support block 272, a fixed cylinder 2740 is fixedly connected to the outer side of the second side block 2737, a piston disc 2742 is provided on the inner side of the fixed cylinder 2740, a moving rod 2738 is fixedly connected to the outer side of the piston disc 2742, a stabilizing plate 2739 is fixedly connected to the outer end of the moving rod 2738, a second spring 2741 is fixedly connected between the outer side of the piston disc 2742 and the inner wall of the fixed cylinder 2740, an air box 2733 is fixedly connected to the inner side of the fixed box 271, a piston plate 2734 is provided on the inner side of the air box 2733, a connecting rod 2735 is fixedly connected to the outer side of the piston plate 2734, an mounting block 2732 is fixedly connected to the lower side of the control plate 2722, the mounting block 2732 is fixedly connected to the connecting rod 2735, and a conveying pipe 2736 is fixedly connected between the air box 2733 and the fixed cylinder 2740.

[0029] The gas box 2733 contains gas. When clamping the pipe fitting 12, the slider 274 drives the control plate 2722 to move. The control plate 2722 drives the mounting block 2732 to move. The mounting block 2732 drives the connecting rod 2735 to move. The connecting rod 2735 drives the piston plate 2734 to move, so that the gas in the gas box 2733 is pushed out and enters the inside of the fixed cylinder 2740 through the delivery pipe 2736. The gas pushes the piston disc 2742 to move. The piston disc 2742 drives the moving rod 2738 to move. The moving rod 2738 drives the stabilizing plate 2739 to move closer to the pipe fitting 12. The stabilizing plate 2739 has an arc-shaped structure, which makes it convenient for the stabilizing plates 2739 on the front and rear sides to limit the pipe fitting 12 again, increasing the stability of the pipe fitting 12 during welding.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] During operation, the pipe fitting 12 is first placed on the support block 272. Then, the electric push rod 2731 is controlled to move the side block 2730. The side block 2730 moves the guide block 2728, which in turn moves the inclined plate 2727. The inclined plate 2727 then rotates the linkage plate 2726. Under the action of the rotating rod 2723, the rotating plate 2724, the inclined plate 2725, and the control plate 2722, the sliders 274 on both sides are controlled to move. The sliders 274 move the control plate 275, which facilitates the movement of the clamping plates 2713 on both sides away from each other, thus facilitating the clamping and limiting of both ends of the pipe fitting 12. At the same time, the control plate 2713... 75 drives the push plate 2717 to move, and the push plate 2717 drives the abutment rod 2720 to move. Under the action of the contact block 2721, the inclined plate 1 2715, and the slider 279, the clamping plates 2713 on the front and rear sides move closer to each other, so that the clamping plates 2713 can clamp and limit the pipe fitting 12. At the same time, the control plate 2722 drives the mounting block 2732 to move. Under the action of the connecting rod 2735, the piston plate 2734, the air box 2733, the conveying pipe 2736, the fixed cylinder 2740, the piston disc 2742, and the moving rod 2738, the stabilizing plates 2739 on both sides limit the pipe fitting 12 again, increasing the stability of the pipe fitting 12 during welding.

[0032] During the welding process, the motor 4 is started to drive the gear 9 to rotate, the gear 9 drives the gear ring 6 to rotate, and the gear ring 6 drives the welding gun 7 to rotate, so that the welding gun 7 can weld the connection of the pipe fitting 12. After the welding is completed, under the action of the gear 2743 and the toothed plate 278, the clamping plate 2713 is rotated to facilitate the placement of the pipe fitting 12 next time.
