Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts welding, and more specifically, to an anti-deformation tool for Y-shaped pipe welding. Background Art

[0002] After welding, Y-shaped tube products are easily deformed due to thermal expansion and contraction, which can easily affect the size of the Y-shaped tube products, making the products unqualified and requiring rework or re-dimensioning of the welded products to meet the processing requirements. Therefore, the deformation of the products after welding not only affects the product size, but also ultimately affects the subsequent continuous construction of the products and the efficiency of product processing. After welding, the existing products are subjected to anti-deformation operations, but the anti-deformation effect is uncontrollable and cannot meet the requirements for ensuring the precise size of the products after welding. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an anti-deformation tool for Y-type tube welding, including a tool body, which is a cross-shaped tool with thickness. The circular diameter formed by the outer circumference of the tool body is exactly matched with the inner diameter of the end of the Y-type tube. One pair of ends of the tool body are arranged opposite to each other and are exactly arranged at two opposite welds of the Y-type tube, and the other pair of ends are exactly arranged at a 90-degree position perpendicular to the two welds of the Y-type tube. When the Y-type tube is welded, its end is arranged on a mounting seat, and the mounting seat is corresponding to a connecting seat that is sleeved and connected to the end of the Y-type tube, and the tool body is connected to the mounting seat instead of the connecting seat.

[0005] Preferably, the four ends of the tool body are all square, and the ends of the tool body are cut at the edges and corners on one side inside the Y-shaped tube to form inclined guide surfaces.

[0006] Preferably, the tool body is provided with avoidance holes for avoiding components on the mounting seat.

[0007] Preferably, a connecting column is fixedly provided at the center of the tool body, and is inserted into the mounting seat to achieve connection with the mounting seat.

[0008] Preferably, a through hole is provided in the mounting seat, which can just accommodate the connecting column to be inserted therein to realize the installation of the tooling body.

[0009] Preferably, a through hole is provided in the mounting seat, which accommodates the connecting column to be freely inserted and protrudes out of the mounting seat, and the end of the connecting column has an external thread and is threadedly connected and fixed by a nut outside the mounting seat.

[0010] The utility model at least has the following beneficial effects:

[0011] 1. The anti-deformation tooling of the utility model has been installed before welding, and can ensure that the welded product will not be deformed during or after welding, thereby ensuring the accurate size of the product after welding.

[0012] 2. The anti-deformation tooling of the utility model has a simple structure and replaces a part of the structure of the original equipment, does not affect the welding of the product, and can also realize the anti-deformation of the Y-shaped pipe after welding.

They do not indicate or imply 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.

[0022] like Figures 1 to 4 As shown, the utility model provides an anti-deformation tool for Y-tube welding, including a tool body 1, which is a cross-shaped with thickness, the circular diameter formed by the outer periphery of the tool body 1 is exactly matched with the inner diameter of the end of the Y-tube 2, one pair of ends of the tool body 1 is exactly arranged at two opposite welds of the Y-tube 2, and the other pair of ends is exactly arranged at a 90-degree position perpendicular to the two welds of the Y-tube 2; when the Y-tube 2 is welded, its end is arranged on a mounting seat 3, and the mounting seat 3 is correspondingly sleeved with a connecting seat 4 connected to the end of the Y-tube 2, and the tool body 1 is connected to the mounting seat 3 instead of the connecting seat 4.

[0023] The four ends of the tool body 1 are respectively located at the weld position and at a position perpendicular to the weld at 90 degrees. This setting position achieves the best welding anti-deformation effect. The four ends of the tool body 1 can support the end of the Y-shaped tube 2 tightly against anti-deformation. The tool body 1 is set to have a certain thickness, which can stably support the end of the Y-shaped tube 2. Figure 3 As shown, in the existing construction, the Y-tube 2 is directly sleeved on the connecting seat 4 for welding, while the tooling body 1 of the present application replaces the connecting seat 4 to achieve the sleeve arrangement and anti-deformation effect of the Y-tube 2. During welding, the tooling body 1 is first installed on the mounting seat 3, and then the Y-tube 2 is installed. After the welding is completed, the Y-tube 2 and the tooling body 1 inside are formed into a whole, and the whole is removed for cooling or withdrawn from the mounting seat 3 for cooling.

[0024] In another embodiment, the four ends of the tooling body 1 are all square, and the end of the tooling body 1 is cut at the corners on one side of the inner part of the Y-shaped tube 2 to form an inclined guide surface 5. The guide surface 5 is an inclined surface, which facilitates the Y-shaped tube 2 to be inserted along the guide surface 5 and sleeved on the outside of the tooling body 1 to achieve a guiding effect.

[0025] In another embodiment, an avoidance hole 6 is provided on the tooling body 1, which is used to avoid the components on the mounting seat 3. A pin shaft is provided on the mounting seat 3, and the avoidance hole 6 is provided at the corresponding position, so that when the tooling body 1 is installed, the avoidance installation can be achieved through the avoidance hole 6.

[0026] In another embodiment, a connecting column 7 is fixedly provided at the center of the tool body 1, which is inserted into the mounting seat 3 to achieve connection with the mounting seat 3. The installation position of the tool body 1 is positioned and guided by the connecting column 7, so that the installation position is accurately positioned and installed.

[0027] In another embodiment, the mounting seat 3 is provided with a through hole 8, which just accommodates the connecting column 7 to be inserted therein to realize the installation of the tool body 1, that is, the through hole 8 and the connecting column 7 have the same size to realize the fit. Figure 3 The through holes 8 on the original connecting seat correspond to each other.

[0028] In another embodiment, the mounting seat 3 is provided with a through hole 8, which accommodates the connection column 7 to be freely inserted and protrudes outside the mounting seat 3. The end of the connection column 7 has an external thread and is threadedly connected and fixed by a nut outside the mounting seat 3. The size of the through hole 8 is slightly larger than the diameter of the connection column 7, so that the connection column 7 can freely pass through the through hole 8, and the connection column 7, i.e., the tool body 1, is fixed by the nut; after welding is completed, the nut is removed to facilitate the quick and convenient disassembly of the tool body 1 and the mounting seat 3.

[0029] In one specific example of the tooling body 1 of the present application, the corresponding dimensions are set as: width 10±0.5mm, length 82.1±0.5mm, diameter Φ6.8±0.5mm, width 15±0.5mm, and curvature R8±0.3mm of the guide surface.

[0030] The construction method of this application is:

[0031] 1. Before starting work, place the main body of the welding anti-deformation tool on the mounting seat of the welding tool;

[0032] 2. Place the Y-shaped tube on the welding tooling, and when the welding work starts, the Y-shaped tube welding work is completed;

[0033] 3. Then take out the Y-shaped tube together with the anti-deformation tooling, i.e. the tooling body, and place them in the area to be inspected;

[0034] 4. After a certain period of time, the temperature of the Y-tube gradually decreases and approaches the temperature. The anti-deformation tooling is taken out and separated from the product. The anti-deformation tooling is continued to be installed on the welding tooling and used repeatedly.

[0035] It can be understood that the present invention is described by some embodiments, and those skilled in the art know that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation mode. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, other modifications can be easily realized.
