Technical Field

[0001] The utility model provides a welding fixture for mechanical processing, belonging to the technical field of welding fixtures. Background Art

[0002] Welding is a processing technology that uses heating or pressurization, or both, to achieve atomic bonding of workpieces to form a permanent connection. Welding is widely used in manufacturing, construction, automobile manufacturing, aerospace and other fields. It is one of the indispensable technologies for modern industrial production and structural assembly. According to different welding methods, such as manual arc welding, gas shielded welding, laser welding, resistance welding, etc., it can adapt to the needs of different materials and application scenarios to achieve efficient connection of metals and other thermoplastic materials.

[0003] In the welding industry, welding of cylindrical materials has always been a difficult point, mainly because the positioning of the workpiece is more difficult. When performing welding positioning, the welding rod or welding wire needs to contact the welding material to form a molten pool. Therefore, the cylindrical material is easy to roll during positioning, which requires workers to fix the material. For two materials with the same diameter and their axes are in the same plane after welding, they can be quickly positioned after being placed on a plane and adjusted and fixed. However, for two materials with the same diameter and their axes are staggered after welding, two materials with different diameters and their axes are in the same plane after welding, and two materials with different diameters and their axes are staggered after welding, their adjustment and positioning are more difficult, requiring workers to spend more time, affecting workers' work efficiency.

[0006] As an improvement, the four upper corners of the base are provided with lifting ears;

[0007] As an improvement, the angle adjustment mechanism includes a connecting platform 1 and a connecting platform 2 arranged at the end of the external threaded rod, and connecting shafts are respectively arranged on both sides of the connecting platform 1 and the connecting platform 2, and the two connecting shafts of the connecting platform 1 and the connecting platform 2 on the same side are respectively rotatably connected to the lower part and the upper part of the connecting plate;

[0008] As an improvement, the rotating platform includes a lower rotating platform arranged above the connecting platform 2, a T-shaped platform is fixedly arranged above the lower rotating platform, and an upper rotating platform is rotatably connected to the outer side of the T-shaped platform;
