[0012] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0013] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0014] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fixed connection" and "fixed connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0015] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments. Figure 1As shown, a positioning welding device for a water pipe assembly at the head of a solar water collector comprises a base 1, a replaceable bottom plate 2, a vertical beam 3, a horizontal beam 4, a pressure rod 5, a pressure head 6, a connecting block 7, a U-shaped block 8, a water pipe positioning plate 9 and a plurality of connecting piece positioning pins 10; the horizontal beams are divided into two groups, each group has two beams, which are respectively fixed on both sides of the base, a U-shaped block is fixed on the top of each horizontal beam, the U-shaped block has a slot, the direction of the slot is toward the side, the two ends of the horizontal beam are respectively installed in the slots of the two U-shaped blocks, the connecting block is fixed in the middle of the horizontal beam, the two ends of the connecting block are respectively threadedly connected with the pressure rod, the lower end of the pressure rod is fixed with the pressure head, rotating the pressure rod can drive the pressure head to move up and down, and the pressure head presses and fixes the upper part of the lower collector assembly.

[0016] The replaceable bottom plate is installed on the base. The replaceable bottom plate can be replaced according to different products. Similarly, the water pipe positioning plate can also be replaced. They are all fixed to the base by bolts. Positioning pins for positioning the connecting piece are provided on both sides of the replaceable bottom plate. The positioning pins are relatively short and can cooperate with the small round holes on the connecting piece. There are several positioning pins for several small round holes on the connecting piece. The water pipe positioning plate is fixed on one side of the base. The water pipe positioning plate is provided with a through hole 11, which corresponds to the round hole of the flange on the water pipe to be welded. The water pipe flange is fixed by passing bolts through the through hole, thereby fixing the position of the water pipe.

[0017] In order to facilitate the rotation of the base, a rotating shaft 12 is fixed on the left and right sides of the base, and the base is installed on the bracket through the rotating shaft so that the entire base can rotate.

[0018] In order to facilitate the rotation of the pressure rod, the upper end of the pressure rod is provided with a through hole 13 for inserting the plate rod.

[0019] In the present invention, since the position of the connecting piece in this type of assembly is relatively special, a strip block 14 is fixed on one side of the replaceable bottom plate, and the connecting piece positioning pin on this side is fixed on the strip block.

[0020] like Figure 2 As shown, when in use, place the collector assembly 15 in the middle of the replaceable bottom plate, which has two positioning columns 16 in the middle to position the collector assembly. Then, place the connecting piece 17 on both sides of the collector assembly. Under the action of the connecting piece positioning pin, the position of each connecting piece will be very accurate. Finally, place the water pipe 18 on the upper part of the collector assembly, align the round hole on the flange at the end of the water pipe with the through hole on the water pipe positioning plate, and then fix it with bolts. After all the components are assembled, they can be welded, or welded once after each component is assembled.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
