[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Refer to Figures 1-3 , a production and assembly positioning device for a tank cleaning guide rod pre-treatment device, comprising: a workbench 3, on which a first slide rail 4 and a second slide rail 12 are fixedly connected. The first slide rail 4 and the second slide rail 12 have the same structure and are arranged at intervals; a first slide table 7 is movably connected to the first slide rail 4, and a plurality of first clamp groups 5 and a round pipe locking block 6 are fixedly connected to the first slide table 7; a second slide table 11 is slidably connected to the second slide rail 12, and a second clamp group 10 and a round pipe locking block 6 are fixedly connected to the second slide table 11; the round pipe locking block 6 fixes the PPR fixed-length pipe fitting 2 to prevent the PPR fixed-length pipe fitting 2 from sliding, and the first clamp group 5 and the second clamp group 10 fix the round pipe locking block 6. Moreover, PPR plugs 1 are welded to both ends of the PPR fixed-length pipe fitting 2. And a relatively convenient sliding guide rail is provided by the first slide rail 4 and the second slide rail 12, while controlling the workpiece to move linearly to prevent deviation in the fusion welding angle of the PPR pipe. The PPR fixed-length pipe fitting 2 is connected to the tee through a PPR pipe welding machine 8.

[0017] A three-way locking module 9 is provided between the first slide rail 4 and the second slide rail 12. The three-way locking module 9 includes a first module and a second module that matches the first module. A vertical slot is provided in the second module, and a horizontal slot is provided in both the first module and the second module. The vertical slot fits with the PPR three-way pipe fitting. After combining the first module and the second module, the three-way can be firmly fixed to prevent movement and angular deviation during welding.

[0018] Further, a first clamp group 5 is provided on each side of the round pipe locking block 6, and the two first clamp groups 5 are respectively located at both ends of the round pipe locking block 6.

[0019] Further, the inside of the round pipe locking block 6 is a semi-circular concave clamping groove, and the clamping groove fits with the outer shape of the round pipe.

[0020] After the pipe fitting is welded, a hole is drilled in the pipe fitting through the hole-opening positioning plate 13. The cross-section of the hole-opening positioning plate 13 is a semi-circular ring, and its size matches the length of the round pipe of the workpiece welding assembly. Positioning holes are pre-opened according to process requirements at the upper part.

[0021] During installation, each component is fixed on the workbench 3 according to the rules to form an integral device. The first slide rail 4 is fixed on the workbench 3, and the first slide table 7 is connected to the first slide rail 4 through a linear bearing to form a smoothly sliding platform; the first clamp group 5 and the round pipe locking block 6 are fixed on this sliding platform; the above structures are combined to form the left-side structure, and the right-side structure is the same as the left-side structure and forms a symmetrical structure in layout.

[0022] The three-way locking module 9 is fixedly arranged in the middle of the workbench 3. The center line of the horizontal circular slot is parallel to the circular slots on both sides of the round pipe locking block 6, and the center lines of the circular slots in the left, middle, and right parts correspond; this structure makes the center lines of the PPR pipes on both sides and the PPR three-way in the middle on the same line, thus ensuring that the pipe fittings are straight and non-bent after butt joint.

[0023] As Figure 2 shown, the three-way locking module 9 is divided into two parts, the first module and the second module. Horizontal slots with semi-circular cross-sections are respectively provided in the horizontal direction. After the two parts of the first module and the second module are buckled, they can completely fit with the PPR three-way to prevent the three-way from moving forward and backward. A hole that fits with the outer shape of the three-way joint is provided in the vertical direction of the three-way locking module 9, so that the three-way interface is completely embedded. Thus, the three-way is firmly fixed from two directions to prevent the three-way from shaking due to the thrust during welding.

[0024] During work, the PPR fixed-length pipe fitting 2 that has been cut to a fixed length is placed in the round pipe locking block 6, and enough length for fusion welding is reserved on the right side. Then the first clamp group 5 is tightened to prevent the PPR fixed-length pipe fitting 2 from moving; the same operation is performed on the right side.

[0025] Place the PPR tee fitting into the middle groove of the tee locking module 9 and lock the first module to firmly fix the tee fitting.

[0026] Install a welding head on the PPR pipe welder 8 that matches the PPR fixed-length pipe fitting 2 to be welded and preheat it; when the temperature reaches, first insert the male side of the welding head into the PPR tee; then push the PPR fixed-length pipe fitting 2 through the slider into the welder, so that the PPR fixed-length pipe fitting 2 and the tee are heated in the welder for a certain period of time simultaneously.

[0027] Then move the slider, pull out the welder, and at the same time immediately insert the heated section of the PPR into the tee. After cooling, it can be fixed and formed. When welding the right-side PPR fixed-length pipe fitting 2 and the tee, the same operation mode is adopted.

[0028] Then, without moving the welded pipe fittings, perform welding operations on the PPR plugs on both sides. After all the welded parts are cooled and welded, loosen all the circular pipe locking blocks 6 and the clamps, remove the PPR pipe assembly, use the hole-opening positioning plate 13 to make drilling positioning marks on the left and right straight pipes of the assembly respectively, and then perform the drilling operation.

[0029] The number of devices and the processing scale described here are used to simplify the description of the present utility model. The application, modification, and variation of the present utility model are obvious to those skilled in the art.

[0030] Although the embodiments of the present utility model have been disclosed as above, it is not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to the specific details and the illustrated examples described here.
