Description

Technical Field

[0001] The utility model relates to the technical field of welding machines, in particular to a precision positioning welding machine. Background Art

[0002] A head is a component used to seal the end of a container to isolate the internal and external media, also known as an end cap. The heads of cylindrical containers are generally rotating shells. According to the shape of the head surface, it can be divided into convex, conical, flat, and combined shapes. A convex head refers to a head with a convex outer surface, such as a hemispherical, elliptical, dished, and spherical head without folding edges. The head needs to be processed using a welding machine during the processing process. There are many types of welding machines, including single-point single-function, single-point dual-function, and single-point multi-function (this type of welding machine also has only one welding head, and after changing the form of the positioning plate, it can be used for welding at any angle between 90° and 180°); there are also two-point, three-point, four-point, and even six-point welding machines and four-corner welding machines. Different types of welding machines have different welding functions and work efficiency.

[0003] At present, most welding machines usually adopt longitudinal and transverse adjustment structures in conjunction with vertical and transverse brackets to achieve the adjustment of the left and right and up and down positions of the welding head of the welding machine, and cooperate with the angle adjustment mechanism to adjust its angle, so that it can accurately locate the position where the head needs to be processed, so that its processing accuracy is higher. However, some waste gas and smoke will be generated during the welding process. If it is not processed, it will spread to the surrounding polluting environment or endanger human health. Most welding machines lack the function of cleaning the waste gas and smoke generated by welding, which is inconvenient to use and has relatively poor practicality. Utility Model Content
