Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and particularly relates to a device for controlling the welding deformation of fusion welding. Background Technique

[0002] Fusion welding is a metal welding method. During the welding process, the welding joint is heated to a molten state by a heat source such as high temperature. Since the workpieces to be welded are closely attached, under the action of the temperature field, gravity, etc., the molten metal liquids of the two workpieces will be mixed. After the temperature drops, the molten part solidifies, and the two workpieces are firmly welded together. This method can form a firm welding joint and is widely used in the fields of automobiles, ships, aerospace, etc.;

[0003] At present, it is found in actual fusion welding operations that due to the large temperature change of the material before and after, the temperature gradient value is too high, resulting in easy deformation in the welding area, affecting the product quality and being not conducive to high-efficiency welding operations;

[0004] To solve the above problems, a device for controlling the welding deformation of fusion welding is proposed in this application. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device for controlling the welding deformation of fusion welding, which solves the problems put forward in the above background technique.

[0010] Further, a chute is arranged inside the sliding seat, which is used to slidingly install a slider at one end of the telescopic guide rod.

[0011] Further, a protruding ring seat is provided on the outer side of the upper end of the welding gun, and a ring frame is rotatably installed on the outer side thereof. The other end of the telescopic guide rod is rotatably connected to the ring frame.

[0013] Further, ball bearings are provided inside both ends of the sliding seat to abut against the inner wall of the slideway, so as to avoid the situation of tilting and jamming due to gravity.

[0014] The utility model has the following beneficial effects:

[0015] By installing the spray head, the utility model can use the telescopic conduit to adjust the use height according to workpieces with different structures, and then preheat the workpiece before welding, so as to reduce the temperature gradient during the welding operation, ensure that the workpiece will not be deformed due to temperature changes during welding, and guarantee the operation quality.
