Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary tooling technology, specifically a welding positioning welding tooling. Background Technology

[0002] Welding is a critical process in the production of brackets, and the positioning accuracy before welding directly determines the final dimensional accuracy and assembly performance of the bracket. Currently, the industry mostly uses manual alignment for welding positioning of this type of bracket: operators hold the product, adjust its position based on experience, perform spot welding to fix it, and then complete the overall welding.

[0003] This traditional positioning method has obvious drawbacks: First, the positioning accuracy is low, and manual adjustment makes it difficult to ensure that there are no gaps between the mating surfaces of the products, which can easily lead to component misalignment and dimensional deviations after welding, resulting in a high rework rate; Second, the production efficiency is low, and a single person takes a long time to position the product, which cannot meet the needs of mass production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a welding positioning welding fixture, which solves the problems of low positioning accuracy, difficulty in ensuring no gaps between the mating surfaces of products due to manual adjustment, easy misalignment of welded parts, dimensional deviations, and high rework rates; secondly, low production efficiency, with long single-person positioning time, which cannot meet the needs of mass production.

[0005] This utility model provides the following technical solution: a welding positioning welding fixture, including a base, a first product, and a second product. A limiting plate is fixedly installed inside the base. Multiple sets of pin columns are fixedly connected to the upper surface of the base and the surface of the limiting plate. A first stop is provided at one end of the base, and a second stop is provided at the other end of the base.

[0006] The number of pin posts is eight sets. The first stop and the second stop cooperate with the pin posts to ensure that the first product and the second product have no gaps when placed together.

[0007] Preferred technical solution 1: The first stop and the second stop are fixed to the base by welding or bolt connection.

[0008] Preferred technical solution 2: The base, limiting plate, pin column, first stop block and second stop block are all made of 45# steel.

[0009] Preferred technical solution three: The surfaces of the base, limiting plate, pin post, first stop and second stop are free from bending deformation, dents, defects, dents, corrosion, sharp edges and sharp corners.

[0010] Compared with the prior art, this utility model provides a welding positioning fixture with the following advantages: First, the first product is aligned with the pins on the surface of the limiting plate and slowly lowered so that the lower surface of the first product is in contact with the limiting plate. Then, the second product is aligned with the pins on the upper surface of the base and slowly lowered so that the second product is in contact with the first product. After that, the positioned first and second products are welded according to the welding process requirements. After welding, the workpiece is cooled and then slowly lifted so that the positioning holes of the first and second products are disengaged from the pins. After the finished product is removed, the welding slag and debris on the surface of the base, the limiting plate, and the pins are cleaned. In the entire welding process, this fixture achieves precise positioning and gapless fit of the first and second products through the coordinated action of various components, ensuring welding quality and efficiency.

[0015] Please see Figure 1-3 ,

[0016] Example 1: A welding positioning welding fixture includes a base 1, a first product 6, and a second product 7. A limiting plate 2 is fixedly installed inside the base 1. Multiple sets of pin columns 3 are fixedly connected to the upper surface of the base 1 and the surface of the limiting plate 2. A first stop 4 is provided at one end of the base 1, and a second stop 5 is provided at the other end of the base 1.

[0017] There are eight sets of pin posts 3. The first stop block 4 and the second stop block 5 cooperate with the pin posts 3 to ensure that there is no gap between the mating surfaces of the first product 6 and the second product 7 after they are placed.

[0018] Example 2: The difference between this example and Example 1 is that the first stop 4 and the second stop 5 are fixed to the base 1 by welding or bolt connection.

[0019] Example 3: The difference between this example and Example 1 is that the base 1, the limiting plate 2, the pin column 3, the first stop block 4 and the second stop block 5 are all made of 45# steel.

[0020] Example 4: The difference between this example and Example 1 is that the surfaces of the base 1, the limiting plate 2, the pin column 3, the first stop block 4 and the second stop block 5 are free from bending deformation, dents, defects, dents, corrosion, sharp edges and sharp corners.

[0021] In summary, this welding positioning fixture first aligns the first product 6 with the pins 3 on the surface of the limiting plate 2 and slowly lowers it so that the lower surface of the first product 6 is in contact with the limiting plate 2. Then, the second product 7 is aligned with the pins 3 on the upper surface of the base 1 and slowly lowered so that the second product 7 is in contact with the first product 6. After that, the positioned first product 6 and second product 7 are welded according to the welding process requirements. After the welding is completed, the workpiece is slowly lifted after cooling so that the positioning holes of the first product 6 and second product 7 are disengaged from the pins 3. After the finished product is removed, the welding slag and debris on the surfaces of the base 1, limiting plate 2, and pins 3 are cleaned. Throughout the welding process, this fixture achieves precise positioning and gapless fit of the first product 6 and second product 7 through the coordinated action of various components, ensuring welding quality and efficiency.
