A hot melt plate 6 is fixedly installed at one end of the swing plate 5. A drive positioning component 7 is provided on the upper surface of the processing table 1.

[0019] like Figure 2 , 3As shown, the drive positioning assembly 7 includes two first hydraulic cylinders 701, two moving plates 702, and a slide groove 704. The two first hydraulic cylinders 701 are fixedly mounted on the upper surface of the processing table 1. The two moving plates 702 are slidably mounted on the upper surface of the processing table 1. The slide groove 704 is formed on the upper surface of the processing table 1. The output ends of the two first hydraulic cylinders 701 are respectively disposed on the surfaces of the two moving plates 702. A slider 710 is fixedly mounted on the lower surface of each of the two moving plates 702, and the slider 710 is slidably mounted inside the slide groove 704. A lower clamping plate 703 is fixedly mounted on the upper surface of each of the two moving plates 702. A second hydraulic cylinder 705 and a guide rod 706 are fixedly installed on the upper surface of the movable plate 702. A guide plate 707 is fixedly installed at the output end of the second hydraulic cylinder 705. The guide plate 707 is slidably installed in the middle of the guide rod 706. An upper clamping plate 708 is fixedly installed at the top of each of the two guide plates 707. The upper clamping plate 708 is located directly above the lower clamping plate 703. The two guide plates 707 are connected by a telescopic rod 709. Two drainage pipes are respectively set between the two lower clamping plates 703 and the upper clamping plate 708. At this time, the second hydraulic cylinder 705 extends and retracts. And because the upper surfaces of the two movable plates 702 are respectively A second hydraulic cylinder 705 and a guide rod 706 are fixedly installed. A guide plate 707 is fixedly installed at the output end of the second hydraulic cylinder 705. A guide plate 707 is slidably installed in the middle of the guide rod 706. An upper clamping plate 708 is fixedly installed at the top of each guide plate 707. The upper clamping plate 708 is located directly above the lower clamping plate 703. The two guide plates 707 are connected by a telescopic rod 709. At this time, both upper clamping plates 708 can be driven to move downwards simultaneously, fixing the drain pipe between the upper clamping plate 708 and the lower clamping plate 703, thus fixing the two drain pipes. At this time, the rotating shaft 4 is driven to rotate by the output end of the servo motor 3. This allows the swing plate 5 to swing, placing the hot melt plate 6 between the two pipes. The output ends of the two first hydraulic cylinders 701 extend and retract, driving the two moving plates 702 to move, bringing the tops of the two pipes together on the surface of the hot melt plate 6 for hot melting.

[0020] The working principle of this water supply and drainage pipe welding device:

[0021] In use, when welding drainage pipes is required, first, place the two drainage pipes between the two lower clamping plates 703 and the upper clamping plate 708 respectively. Then, the second hydraulic cylinder 705 extends and retracts at its output end. Since the second hydraulic cylinder 705 and guide rod 706 are fixedly installed on the upper surfaces of the two moving plates 702 respectively, and a guide plate 707 is fixedly installed on the output end of the second hydraulic cylinder 705, and the guide plate 707 is slidably installed in the middle of the guide rod 706, with an upper clamping plate 708 fixedly installed at the top of each guide plate 707. The upper clamping plate 708 is located directly above the lower clamping plate 703, and the two guide plates 707 are connected by a telescopic rod 709. This allows both upper clamping plates 708 to be driven to move downwards simultaneously, fixing the drainage pipes to the upper clamping plate 708. Between the lower clamping plates 703, the two drain pipes are fixed. At this time, the output end of the servo motor 3 drives the rotating shaft 4 to rotate, which in turn drives the swing plate 5 to swing, placing the hot melt plate 6 between the two pipes. Then, the output ends of the two first hydraulic cylinders 701 extend and retract, driving the two moving plates 702 to move, so that the tops of the two pipes are attached to the surface of the hot melt plate 6 to perform hot melting. Then, the two pipes are removed from the surface of the hot melt plate 6, and the hot melt plate 6 rotates away from the two pipes. Then, the output end of the first hydraulic cylinder 701 extends and retracts again, and the tops of the two pipes are attached together for a period of time to perform welding. This device can automatically perform docking work and ensure the accuracy of the docking position, thus improving the welding efficiency.
