Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a special tooling for ensuring welding angles. Background Technology

[0002] Welding technology is an operation method that uses welding materials to join two or more base materials into a whole under high temperature or high pressure conditions. Welding technology is mainly applied to metal base materials, and commonly used methods include electric arc welding, argon arc welding, CO2 shielded welding, oxy-acetylene welding, laser welding, electroslag pressure welding, etc. Non-metallic materials such as plastics can also be welded. Welding is a localized rapid heating and cooling process. The welding zone cannot expand and contract freely due to the constraint of the surrounding workpiece. After cooling, welding stress and deformation are generated in the weldment. Important products need to eliminate welding stress and correct welding deformation after welding.

[0003] In existing technologies, flanges often require welding to pipes during production. However, some flanges have different angles between them and the pipe during welding. In such cases, the angle between the flange and the pipe usually needs to be adjusted before welding. This requires the use of special tooling to limit the angle. However, the angle of existing tooling is usually fixed after design. Therefore, when welding flanges with different angles, a single tooling cannot meet the needs of products with different angles. As a result, in mass production, tooling needs to be changed frequently, which affects its performance. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A special tooling for ensuring welding angles includes: a base plate 1, a limiting plate 2 on the top surface of the base plate 1, a base plate 7 inside the limiting plate 2, a connecting pipe 8 fixedly installed on the top surface of the base plate 7, and a flange 9 fixedly installed on the top surface of the connecting pipe 8; a positioning frame 3 fixedly installed on the top surface of the base plate 1, a mounting frame 4 slidably connected to one side of the positioning frame 3, a receiving joint 5 on one side of the mounting frame 4, a disc fixedly installed on one side of the receiving joint 5, and two fixing pins 32 slidably connected to one side of the disc; a distance adjustment component on one side of the mounting frame 4 for adjusting the position of the receiving joint 5; and a height adjustment component on one side of the mounting frame 4 for adjusting the height of the mounting frame 4.An adjusting frame 6 is slidably connected to one side of the positioning frame 3. The adjusting frame 6 is fixed to the positioning frame 3 by bolts and nuts. A slide 18 is slidably connected inside the adjusting frame 6. A second spring 22 is movably sleeved on the outer circular wall of the slide 18. Two clamping plates 19 are provided inside the slide 18. Two positioning posts 20 are fixedly installed on the outer circular wall of the clamping plates 19. The positioning posts 20 penetrate the slide 18. A first spring 21 is movably sleeved on the outer circular wall of the positioning posts 20. In use, the operator places the base plate 7 to be welded inside the limiting plate 2, and then places the connecting pipe 8 to be welded inside the slide 18. Multiple first springs 21 push two clamping plates 19 to clamp and fix the connecting pipe 8. During this process, the spacing between the two clamping plates 19 can be adjusted to clamp and fix connecting pipes 8 of different thicknesses. Then, the operator can remove the bolts and nuts on the side of the adjusting frame 6. At this time, the operator can slide the entire adjusting frame 6 up and down along the direction of the positioning frame 3. Then, the operator slides the adjusting frame 6 to insert the bottom of the connecting pipe 8 into the positioning hole on the surface of the base plate 7. Then, as the connecting pipe 8 enters, the slide 18 will be displaced due to the position limit of the connecting pipe 8, thereby causing the slide to move. 18. Slides inside the adjusting bracket 6 and compresses the second spring 22, thereby fixing the positions of the base plate 7 and the connecting pipe 8. After the above step is completed, the operator aligns the flange 9 with the disc on one side of the socket 5 and fixes the flange 9 with two fixing pins 32. Then, the operator uses the distance adjustment component and the height adjustment component to adjust the working distance and height of the socket 5, thereby using connecting pipes 8 of different heights and diameters. Then, the operator can rotate the socket 5 to adjust the welding angle of the flange 9 so that it fits against the top of the connecting pipe 8. After the above step is completed, the base plate 7 and the connecting pipe 8 are aligned. The base plate 7, connecting pipe 8, and flange 9 are assembled into a single unit, allowing workers to weld them. During this process, since the positions of the base plate 7, connecting pipe 8, and flange 9 are fixed, workers do not need to individually measure the dimensions of each component before welding. Furthermore, the clamping plate 19 can hold connecting pipes 8 of different diameters, and the working height, distance, and angle of the socket 5 are adjustable. This facilitates welding of base plates 7, connecting pipes 8, and flanges 9 of varying diameters, improving the adaptability of the tooling.

[0030] Based on the above embodiments, refer to Figure 2 and Figure 3The distance adjustment assembly includes: an adjustment head 12, which is located on one side of the mounting frame 4 and is fixed by bolts, nuts, and a connector 5. A rack 13 is fixedly installed on one side of the adjustment head 12. An adjustment wheel 17 is rotatably connected to one side of the mounting frame 4. A transmission gear 16 is fixedly installed at one end of the adjustment wheel 17, and the transmission gear 16 meshes with the rack 13. The operator can rotate the adjustment wheel 17, which in turn drives the transmission gear 16 to rotate. Under the meshing transmission action of the transmission gear 16 and the rack 13, the rack 13 drives the adjustment head 12 to move laterally. The working distance of the connector 5 and its side disc can be adjusted. At the same time, the bolts and nuts on the side of the adjusting head 12 can be removed, and the working angle of the connector 5 and its side disc can be rotated and adjusted. This makes it easy to adjust the working distance and working angle after the flange 9 is installed, so as to adapt it to the connecting pipes 8 of different heights and diameters. Two guide rods 15 are fixedly installed inside the mounting frame 4, and a guide sleeve 14 is fixedly installed on one side of the adjusting head 12. The guide sleeve 14 is slidably connected to the guide rods 15, which improves the stability of the adjusting head 12 when it moves.

[0031] Based on the above embodiments, refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The height adjustment component includes two mounting holes 26, both located on one side of the mounting frame 4. A first limiting rod 27 is slidably connected inside each mounting hole 26. A fourth spring 28 is movably sleeved on the outer circular wall of the first limiting rod 27. Several limiting grooves are provided on one side of the inner side of the positioning frame 3. The first limiting rod 27 is movably sleeved on the inner circular wall of the limiting groove. The operator can pull the two first limiting rods 27, causing them to move out of the limiting grooves inside the positioning frame 3. At this time, the first limiting rod 27 is positioned relative to the mounting frame. The limiting effect of 4 is released, allowing the operator to slide the mounting frame 4 up and down along the direction of the positioning frame 3, thereby adjusting the working height of the connector 5 to accommodate different heights of the connecting pipe 8. Two first mounting caps 23 are fixedly installed on one side of the mounting frame 4. A third spring 24 is movably sleeved inside the first mounting cap 23, and a positioning block 25 is movably sleeved inside the first mounting cap 23. Several limiting grooves are opened on one side of the adjusting wheel 17, and the positioning block 25 is movably sleeved with the inner circular wall of the limiting groove. When rotating, the adjusting wheel 17 presses against multiple positioning blocks 25, which in turn press against the third spring 24. Then, under the rebound force of the third spring 24, the positioning blocks 25 enter the interior of multiple limiting grooves on one side of the adjusting wheel 17, thus facilitating the limiting and fixing of the receiving joint 5 after distance adjustment. The top surface of the base plate 1 has a mounting groove 10, which is slidably connected to the limiting plate 2. The top surface of the limiting plate 2 has two positioning grooves 11. A second mounting cap 29 is fixedly installed on the top surface of the base plate 1. The inner sliding connection of 29 is a second limiting post 30. The outer circular wall of the second limiting post 30 is movably sleeved with a return spring 31. The second limiting post 30 is movably sleeved with the inner circular wall of the positioning groove 11. The operator can pull the second limiting post 30 upward, which will compress the return spring 31. Then the second limiting post 30 will move out of the inside of the positioning groove 11. At this time, the operator can remove the limiting plate 2 from the inside of the mounting groove 10 and replace it, thereby achieving the effect of replacing the limiting plate 2 to adapt it to different sizes of base plates 7.

[0032] Working principle: Please refer to Figures 1-7As shown, during use, the worker places the base plate 7 to be welded inside the limiting plate 2, and then places the connecting pipe 8 to be welded inside the slide 18. Multiple first springs 21 inside the slide 18 then push two clamping plates 19 to clamp and fix the connecting pipe 8. During this process, the spacing between the two clamping plates 19 can be adjusted to clamp and fix connecting pipes 8 of different thicknesses. Then, the worker can remove the bolts and nuts on the side of the adjusting frame 6. At this time, the worker can slide the entire adjusting frame 6 up and down along the direction of the positioning frame 3. The worker then slides the adjusting frame 6 so that the bottom of the connecting pipe 8 is inserted into the positioning hole on the surface of the base plate 7. As the connecting pipe 8 enters, the slide 18 is displaced due to the positional limitation of the connecting pipe 8, causing the slide 18 to slide inside the adjusting frame 6 and press against the second spring 22. This allows the base plate 7 and the connecting pipe 8 to be aligned and fixed. After the above steps are completed, the worker connects the flange 9 to the side of the connector 5... The discs are joined together and the flange 9 is fixed by two fixing pins 32. Then, the operator uses the distance adjustment component and the height adjustment component to adjust the working distance and height of the connector 5, so as to use connecting pipes 8 of different heights and diameters. The operator can then rotate the connector 5 to adjust the welding angle of the flange 9 so that it fits against the top of the connecting pipe 8. After the above steps are completed, the base plate 7, connecting pipe 8 and flange 9 will be integrated into one unit. Then the operator can weld the base plate 7, connecting pipe 8 and flange 9. During this process, since the positions of the base plate 7, connecting pipe 8 and flange 9 are fixed, the operator does not need to measure the dimensions of the base plate 7, connecting pipe 8 and flange 9 separately before welding. At the same time, since the clamping plate 19 can clamp the connecting pipes 8 of different diameters, and the working height, working distance and working angle of the connector 5 can be adjusted, it is easy to weld the base plate 7, connecting pipe 8 and flange 9 of different sizes and diameters, thus improving the adaptability of the tooling.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
