[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0022] As attached Figures 1 to 3A precise positioning welding fixture shown includes a reference plate 1, which is made of Q235 steel and is mainly used to support and provide a reference for workpiece production. It ensures the accuracy and repeatability of the welding process by accurately positioning and fixing the workpiece. An inner gap limit plate 2 is arranged above the reference plate 1. The inner gap limit plate 2 is made of 45 steel and mainly controls the positioning size of the inner gap. It is usually fixed to the specified position of the reference plate 1 by bolts to ensure its stability and reliability. By limiting the movement of the workpiece, the inner gap limit plate 2 ensures that the workpiece remains fixed during the welding process, thereby improving the welding accuracy and quality. A support plate 3 is arranged on one side of the inner gap limit plate 2. The height of the support plate 3 needs to be milled to 105mm and is fixed to the reference plate by bolts or welding to ensure its stability and reliability. It is mainly used to enhance the stability of the fixture in the vertical and horizontal directions and prevent the workpiece from being displaced or deformed due to vibration, impact or other external forces. Component outer gap limit plates 4 are arranged on both sides above the reference plate 1. The component outer gap limit plates 4 need to be precisely processed during the manufacturing process. , ensure the surface roughness and dimensional accuracy of the outer opening limit plate 4 of the component to provide a stable positioning effect. The surface is usually treated with rust prevention and wear resistance to ensure durability for long-term use. The main function of the outer opening limit plate 4 of the component is to control the outer opening size of the component. By limiting the activity of the workpiece, the outer opening limit plate 4 of the component ensures that the workpiece remains fixed during the welding process, thereby improving the welding accuracy and quality. A No. 1 rib plate height positioning plate 5 is arranged on one side of the inner opening limit plate 2. The No. 1 rib plate height positioning plate 5 is mainly used to control the positioning size of the height of the parts to prevent vertical displacement caused by vibration, impact or other external forces. The No. 1 rib plate height positioning plate 5 is composed of two parallel plate structures made of 45 steel materials. A component length positioning plate 6 is arranged on one side of the No. 1 rib plate height positioning plate 5. The component length positioning plate 6 is mainly used to control the total length of the component. A No. 1 rib plate 7 is arranged on one side of the component length positioning plate 6. The No. 1 rib plate 7 is mainly used to support the component length positioning plate 6. The structural stability of the component length positioning plate 6 is ensured by arranging two groups evenly horizontally on its back;

[0023] The top of the inner opening limit plate 2 is connected to the No. 2 rib plate height positioning plate 10, and the No. 2 rib plate height positioning plate 10 is installed on the top of the inner opening limit plate 2 by bolts. By combining the two, the workpiece can be accurately positioned in the horizontal and vertical directions at the same time, thereby improving the overall accuracy and quality of welding. The bolt connection method makes it easier to adjust or replace the No. 2 height positioning plate 10 to adapt to workpieces of different sizes or different welding tasks. This flexibility enables the welding tooling to adapt to diverse production needs and improves the versatility and adaptability of the equipment. The top of the No. 1 rib plate height positioning plate 5 is connected to the No. 3 rib plate height positioning plate 11, and the No. 3 rib plate height positioning plate 11 is also connected to the No. 1 rib plate height positioning plate 5 by bolts. Since the bolt connection allows a certain amount of slight movement and adjustment, this helps to reduce internal stress caused by factors such as temperature changes, material expansion or contraction, and this stress reduction helps to extend the service life of the welding tooling.
