Embodiment Construction
[0021] The present invention will be further described below in conjunction with accompanying drawings and examples.
[0022] like Figure 1-3 shown.
[0023] An automatic three-dimensional profiling secondary protection welding unit for welding ball valves, which includes a gantry 1 and a water tank 2, the gantry 1 is located at the rear of the water tank 2, and the water tank 2 is installed on the base and connected to a water circulation treatment system, such as figure 1 shown. Movable sunshade 19 is installed on the water tank 2 (as figure 2 ). The guide rail 3 is installed on the gantry 1, and the welding assembly 4 is installed on the guide rail 3. The welding assembly 4 is on the traveling mechanism 5 (it can be directly driven by the traveling motor, or the motor can drive the screw mechanism to realize the horizontal movement of the welding assembly 4. ) is driven to move left and right along the guide rail 3; the welding assembly 4 is equipped with a lifting g...

Description
technical field [0001] The present invention relates to a kind of welding equipment, especially a kind of special welding equipment for welding ball valves, specifically a special automatic three-dimensional profiling welding unit for welding ball valves which can complete three welding positions of welding ball valves on one piece of equipment . Background technique [0002] At present, welded ball valves are widely welcomed by users for their excellent performance. Welded ball valves, as the name implies, are ball valves formed by welding. At present, each welded ball valve has three annular welds, such as Figure 4 As shown, one is the welding of the valve stem sleeve 21 and the valve casing 23 used to install the operation means. Since the valve stem sleeve 21 is equipped with a sealing ring, great care must be taken during welding to avoid the high temperature generated by welding from affecting the sealing ring. , the other two welds are the welding of the valve pipe...
