Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a welding fixture for positioning angularly when using multiple non-slip flanges. Background Technology

[0002] For argon arc welding of non-loose flanges on the plate surface of products, due to the large number of flanges, high precision, and complex procedures, deformation during the welding process has always been a key factor restricting production efficiency and product quality. Welding thermal stress often leads to significant angular and dimensional changes in welded products. Especially when processing precision flanges, even minor deformations can have a huge impact on the product, making it impossible to meet the stringent requirements of end customers.

[0003] While traditional general-purpose welding fixtures can provide some control over local angularity and dimensions, their precision is insufficient and often fails to meet the demands of high-precision welding. Furthermore, general-purpose fixtures present numerous inconveniences in shape correction, wasting significant time and manpower. For non-slip flanges, due to the diversity of their structure and dimensions, general-purpose fixtures struggle to achieve effective positioning and fixation, further exacerbating the risk of welding deformation.

[0004] Therefore, in order to overcome the shortcomings of existing technologies and improve the accuracy and efficiency of argon arc welding of non-loop flanges, it is necessary to provide a dedicated welding fixture. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a welding fixture for angular positioning when multiple non-slip flanges are used. This welding fixture effectively solves problems such as prominent deformation, insufficient welding precision, and time-consuming alignment when welding precision products, thereby improving production efficiency, reducing the labor intensity of workers, and ensuring the quality and precision of welded products.

[0006] The technical solution of this utility model is as follows:

[0007] A welding fixture for positioning multiple non-slip flanges in an angular direction includes a positioning plate set on a product end plate. Several non-slip flanges are to be welded on the product end plate. The positioning plate is placed on the non-slip flanges. The positioning plate is provided with positioning holes corresponding to the non-slip flanges. Positioning elements are installed in the positioning holes to fix the non-slip flanges to the positioning plate.

[0008] The product's mounting plate is equipped with a positioning chuck for positioning non-slip flanges.

[0009] Non-slip flanges come in a variety of different specifications.

[0010] Optionally, the positioning hole is a pin hole, and the positioning element is a positioning pin.

[0011] Optionally, the positioning hole is a threaded hole, and the positioning element is a bolt.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model discloses a welding fixture for locating multiple non-slip flanges in the angular direction. This welding fixture for locating multiple non-slip flanges in the angular direction can achieve precise positioning of the non-slip flanges through the positioning holes on the positioning plate and the corresponding positioning elements (such as positioning pins or bolts), thereby effectively controlling the angular and dimensional changes caused by thermal stress during the welding process, significantly reducing the deformation after welding, and meeting the strict requirements of end customers for precision welded products.

[0014] 2. This utility model discloses a welding fixture for positioning multiple non-slip flanges in an angular direction. This welding fixture for positioning multiple non-slip flanges in an angular direction enables the non-slip flanges to be quickly and accurately assembled onto the product plate, greatly simplifying the preparation work before welding. At the same time, since the fixture can control the deformation during the welding process, it reduces the amount of subsequent straightening work, thereby improving the overall production efficiency. In addition, the use of the fixture also helps the welder to tack weld all the positions to be welded, further ensuring the welding quality.

[0015] 3. This utility model discloses a welding fixture for positioning multiple non-slip flanges in an angular direction. This welding fixture for positioning multiple non-slip flanges in an angular direction is suitable for welding non-slip flanges of different specifications and heights. The positioning holes on the positioning plate can be adjusted or replaced according to the specifications of different flanges, so that the fixture can flexibly meet diverse welding needs.

[0016] 4. This utility model discloses a welding fixture for locating multiple non-slip flanges at an angular angle. This welding fixture facilitates inspection and calibration: after welding, the fixture can be used again to re-inspect the angle and height of the product. If any defects are found, calibration can be performed directly until the product meets the design requirements. This not only improves the product pass rate but also simplifies the inspection and calibration process.

[0017] 5. The present invention discloses a welding fixture for positioning multiple non-slip flanges in the angular direction. This welding fixture for positioning multiple non-slip flanges in the angular direction also takes into account the heat dissipation problem during the welding process. By quickly assembling and disassembling the fixture, the heat generated during welding can be quickly dissipated, reducing the impact of thermal stress on the product and further reducing welding deformation.

[0027] The components represented by the various reference numerals in the diagram are:

[0028] This utility model includes: 1. a product obstruction plate, 11. a positioning plate, 2. a non-slip flange, 21. a first-specification non-slip flange, 22. a second-specification non-slip flange, 3. a positioning plate, 31. a positioning hole, and 4. a positioning pin. Detailed Implementation

[0029] like Figure 1 As shown, the welding fixture for positioning angles when there are multiple non-slip flanges includes a positioning plate 3 set on the product blind plate 1.

[0030] like Figure 2 and Figure 3 As shown, several non-slip flanges 2 are to be welded on the product's sealing plate 1. These non-slip flanges 2 have various different specifications.

[0031] like Figure 4 As shown, the positioning plate 3 is placed on the non-slip flange 2 and is designed to conform to different flange sizes. The positioning plate 3 has positioning holes 31 corresponding to the non-slip flange 2; these positioning holes 31 can be pin holes or threaded holes. When the positioning hole 31 is a pin hole, the positioning element is a positioning pin 4; when the positioning hole 31 is a threaded hole, the positioning element is a bolt. The non-slip flange 2 is fixedly connected to the positioning plate 3 through the positioning elements, achieving angular positioning.

[0032] In addition, a positioning plate 11 is provided on the product obstruction plate 1 for positioning the non-slip flange 2 to further ensure the accurate placement of the flange.

[0033] like Figures 5 to 7 As shown, when using this fixture for welding, firstly, the perforated non-slip flange is angularly positioned to the conformal positioning fixture using locating pins or bolts. After assembling all flanges, the welder tack welds all positions to be welded. After tack welding, the fixture is removed, and argon arc welding is performed on all positions. After welding is completed and cooled, the fixture is used again to re-inspect the angle and height of the product. If it fails to meet the requirements, it can be directly adjusted until it meets the requirements.

[0034] This utility model is a tooling integrated with assembly, inspection, and calibration designed to ensure precise dimensions in the welding of non-slip flanges. Considering the stringent dimensional requirements of these parts, and the fact that they are machined before welding, an effective solution is needed to prevent defects and ensure the overall dimensional accuracy after welding. This solution can be used for welding non-slip flanges of different specifications and sizes, guaranteeing a angular dimensional accuracy of ±0.1° after welding. Example

[0035] The positioning hole 31 is a pin hole, and the positioning element is the positioning pin 4. First, place the positioning plate 3 on the product end plate 1, ensuring that the positioning plate 3 corresponds to the position of the non-slip flange 2. Then, insert the positioning pin 4 into the positioning hole 31, and achieve angular positioning of the flange by having the head of the positioning pin 4 contact the hole wall of the non-slip flange 2. After assembling all flanges, perform tack fixing, welding, and re-inspection steps, the specific operation of which is the same as above. Example

[0036] The positioning hole 31 is a threaded hole, and the positioning element is a bolt. First, place the positioning plate 3 on the product end plate 1, ensuring that the positioning plate 3 corresponds to the position of the non-slip flange 2. Then, screw the bolt into the positioning hole 31, and achieve angular positioning of the flange by pressing the bolt head against the contact surface of the non-slip flange 2. Subsequent operations are the same as in Example 1.

[0037] In both of the above embodiments, the accurate placement of the non-loose flange 2 can be further ensured by setting a positioning bracket 11 on the product obstruction plate 1. Meanwhile, because the tooling design takes into account heat dissipation during welding, it can quickly dissipate the heat generated during welding, reducing the impact of thermal stress on the product and further minimizing welding deformation.

[0038] The positioning plate of the fixture is designed to conform to the shape of non-slip flanges of different specifications, thus allowing control over the assembly height of different flanges. This fixture can also be used for alignment and inspection after welding.

[0039] The welding process can employ welding methods such as TIG and MIG, as well as other connection methods for correction and inspection.

[0040] The tooling is suitable for welding non-slip flanges made of stainless steel, aluminum alloy or titanium alloy.

[0041] In summary, this utility model provides a welding fixture with multiple functions, strong connectivity, and convenient operation. It is suitable for welding non-slip flanges of different sizes and heights, which can significantly improve production efficiency, reduce the labor intensity of workers, and ensure the quality and precision of welded products.
