Description
Technical Field
[0001] This utility model relates to the field of auxiliary tooling technology, specifically a welding tooling fixture. Background Technology
[0002] Welding fixtures are process equipment used to accurately position and fix workpieces during welding, ensuring welding precision. Their core functions include guaranteeing assembly accuracy, improving production efficiency, reducing welding deformation, and adapting to the clamping requirements of different workpieces. Welding fixtures typically consist of a positioning mechanism, a clamping mechanism, a support mechanism, and auxiliary devices. The positioning mechanism ensures accurate workpiece positioning, the clamping mechanism prevents workpiece movement during welding, and the support mechanism provides a rigid foundation. With the development of the manufacturing industry, welding fixtures are evolving towards flexibility, modularity, and intelligence. Flexible fixtures achieve rapid changeover through standardized modules, adapting to the needs of multi-variety, small-batch production and significantly reducing the manufacturing cost of specialized fixtures. Modular design improves the versatility of fixtures; for example, combined fixtures can be adapted to different workpieces by adjusting the positioning blocks and clamping mechanisms, reducing production line adjustment time. The trend towards intelligence is reflected in the application of computer-aided design and automated control technologies, such as laser tracking positioning and robots, enabling real-time quality monitoring. Furthermore, the introduction of new materials reduces the fixture's weight while enhancing durability, allowing it to maintain stable performance even in high-intensity welding environments. Currently, welding fixtures have become a key support for modern intelligent manufacturing, playing an irreplaceable role in improving welding quality and reducing production costs.
[0003] Traditional welding fixtures cannot easily adjust the clamping height when welding round pipes, making it difficult to keep the axis aligned for pipes of different diameters. This requires repeated adjustments or the use of shims, affecting welding accuracy and efficiency. For irregular square pipes, existing fixtures are mostly fixed structures, which cannot adapt to the clamping requirements of square pipes of different sizes, easily leading to welding misalignment. Furthermore, when changing to square pipes of different specifications, the entire set of fixtures needs to be replaced or complex adjustments need to be made, which is cumbersome and time-consuming.

[0028] Furthermore, the right-side bearing V-shaped plate 22 and the left-side bearing V-shaped plate 315 are set with an upward opening angle of 90° in order to hold the lower edge of the square tube.
[0029] Furthermore, the right fixed base 21 and the left fixed base 313 are symmetrically arranged on the top of the A-type base 1 to ensure that the force is evenly distributed at both ends and that it will not tip over during operation.
[0030] Example 2:
[0031] Please see Figure 1-5 Furthermore, in conjunction with Embodiment 1, it is further obtained that the irregular square tube adaptation component 32 includes an irregular adaptation frame 321. The two irregular adaptation frames 321 are slidably installed in the right adaptation frame sliding groove 23 and the left adaptation frame sliding groove 316.

Rotate the bottom screw handle 312 to adjust the screw 311 to adapt the tube size, and adjust the height of the left-side fixed base 313 to ensure that the V-plates on both sides are in full contact with the workpiece, ensuring that the round tube axis is aligned or the square tube is horizontally positioned. After clamping, welding can be performed. If welding tubes of different diameters using a reducer, first place the larger diameter tube on the right-side bearing V-plate 22 for fixation, rotate the bottom screw handle 312 to lower the left-side fixed base 313, and place the smaller diameter tube on the left-side bearing... On the V-shaped plate 315, adjust the large and small tube adapting screws 311 to raise the left-side bearing V-shaped plate 315 to a suitable height, ensuring that the axes of the large and small tubes coincide. After maintaining stability through the base guide post 314, welding is carried out.
