[0010] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0011] like Figures 1-4 The welding fixture shown is a cantilever spot welding fixture for return air grilles, which consists of three main parts: a fixed frame 1, two sets of positioning jigs, and a clamping mechanism.

[0012] The return air grille cantilever (referred to as Product 13 in the following description) has the following structure: Figure 4As shown, it consists of a main body 14 and various accessories 16. The main body 14 is a closed structure composed of multiple main body segments 15 welded end to end, and the accessories 16 are welded onto the main body 14.

[0013] The fixed frame 1 serves as the basic load-bearing structure of the tooling, providing a stable installation platform for the positioning jig 2 and the clamping mechanism. This ensures that the entire tooling remains stable during the welding process and will not shake due to external forces, thus providing a reliable guarantee for the accurate positioning and welding of product 13.

[0014] The positioning fixture 2 set includes multiple positioning fixtures 2 evenly distributed along the contour of product 13, which are fixedly installed on the fixing frame 1. The main function of these positioning fixtures 2 is to provide vertical support for product 13. Each positioning fixture 2 has a limiting groove 4 at the upper end that matches the shape of the corresponding section of product 13. Precise positioning is achieved through the limiting groove 4 that matches the shape of product 13, preventing product 13 from shifting in the vertical and horizontal directions.

[0015] Positioning fixtures are divided into the following types: Main support fixture 5: Used to provide multi-point support for the main body 14 of product 13, evenly distribute the weight of product 13, ensure that product 13 maintains a stable posture during welding, and avoid deformation due to uneven local stress. Through multi-point support, the stability and positioning accuracy of product 13 are effectively improved, providing a good foundation for subsequent welding operations.

[0016] Limiting and fixing fixture 6: A short column 8 is set in its limiting groove 4. The short column 8 can be inserted into the pin hole of product 13 to achieve positioning. This positioning method further improves the accuracy and reliability of product 13 positioning. Through the cooperation of the pin hole and the short column 8, the position of product 13 can be precisely limited to prevent product 13 from rotating or shifting during the welding process and ensure the accuracy of the weld point position.

[0017] Accessory fixing fixture 7: Used to fix the accessory 16 to be welded. The accessory 16 is provided with pin holes and can be connected to the accessory fixing fixture 7 by bolts 9. This design facilitates the installation and fixing of the accessory 16, ensures that the relative position of the accessory 16 and the main body 14 of the product 13 is accurate during welding, and improves the precision and quality of welding.

[0018] Detachable and adjustable design: The positioning fixture 2 and the fixing frame 1 can be detachably connected. This design makes the tooling highly versatile. The positioning fixture 2 can be replaced or its position adjusted according to different product models 13 to adapt to products 13 of various specifications and shapes. There is no need to redesign and manufacture tooling for each product model 13, which greatly reduces production costs and improves production efficiency.

[0019] Height adjustable: The positioning fixture 2 can adopt a two-section structure design, and the overall height can be adjusted. This design can meet the positioning requirements of return air grille products 13 with different thicknesses or heights. At the same time, the lifting stroke of the rotary clamping cylinder 3 covers the height adjustment range of the positioning fixture 2, ensuring that no matter how the height of the positioning fixture 2 is adjusted, the clamping mechanism can effectively clamp and fix the product 13, ensuring the smooth progress of the welding process.

[0020] The clamping mechanism includes at least one rotary clamping cylinder 3, which can be an Airtac ACKL type. It is fixedly mounted on the cylinder seat 10 of the mounting bracket 1. The rotary clamping cylinder 3 is located on one side of the positioning fixture 2 and works in conjunction with it. The movable end 11 of the rotary clamping cylinder 3 has both rotation and lifting functions, and a clamping head 12 is provided at its end. In use, the movable end 11 of the rotary clamping cylinder 3 can rotate to above the product 13 on the positioning fixture 2, and then the clamping head 12 is lowered through the lifting function to clamp and fix the product 13 onto the positioning fixture 2. This design makes the clamping operation more flexible and convenient, enabling quick and accurate fixing of the product 13, improving operational convenience and welding efficiency.

[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
