Description
Technical field
The utility model relates to a kind of welding gun.
Background technology
Inwall welding technology is mainly used on all kinds of petrochemical industry, nuclear pressure container, and built-up welding tubule diameter of bore scope is generally 50 ~ 500mm, and welding machine stroke is 1.5m to the maximum.Welding small diameter inner hole, because aperture is little, length is long, and manual electric arc welding and gas shielded arc welding need manual operation generally will not adopt, existing conventional equipment is generally divided into two kinds, be a hole inner wall overlaying welding equipment of diameter 50 ~ 300mm, adopt argon arc welding head, elongated tubular is the body of a gun, because body of a gun diameter is less of ensureing that the body of a gun does not bend, its length is generally within 2m, and argon arc welding welding efficiency is in addition lower, and welding interval is long; Another kind is the hole inner wall overlaying welding equipment of diameter 300 ~ 500mm, and adopt submerged arc welding machine head, this type of device travel is mostly 6 ~ 7m, but can only be greater than the endoporus of 300mm by built-up welding diameter because head is excessive.Therefore when the inner walls of deep holes needing built-up welding diameter to be less than 300mm length to be greater than 3m, argon arc welding and submerged-arc welding equipment cannot carry out built-up welding.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of Small-deep Hole gas to protect welding gun.
In order to solve the problems of the technologies described above, the utility model comprises welder head, lengthen the body of a gun, tip, cantilever and telescoping mechanism, lengthen the body of a gun and comprise copper pipe, the insulation sleeve being in the wire convey soft pipe in copper pipe and being wrapped in outside copper pipe, welder head is gas shielded arc welding welder head, one end of copper pipe is fixedly connected with the snorkel of welder head, wire convey soft pipe is connected with the wire-feeding pipe of welder head, tip is fixed on the other end of copper pipe, the one end lengthening contiguous tip on the body of a gun bends, lengthening the body of a gun is fixed on cantilever, one end away from tip on cantilever is connected with telescoping mechanism.
Move in body to be welded for ease of tip, realize inboard wall of tube body to weld comprehensively, described telescoping mechanism has the support arm two perpendicular direction motions, cantilever and support arm fix, and the length direction of cantilever, lengthen a direction of motion of the length direction of rifle body and the support arm of telescoping mechanism in the same way.
For the ease of connecting, the two ends of described copper pipe are respectively welded with a threaded joint, and two joints are threaded with the snorkel of welder head and tip respectively.
Described lengthening body of a gun length is 3-5 rice, and copper pipe diameter is 8-12 millimeter, lengthens the length 30-50 millimeter of the curved end of the body of a gun.
Contact inboard wall of tube body to be welded for the ease of tip, the knee angle of the described lengthening body of a gun is 150 degree.
In order to fixing reliable, the described lengthening body of a gun and cantilever are fixed by multiple geometrical clamp.
The beneficial effects of the utility model are: the utility model lengthens the body of a gun especially owing to adopting, making the welding head when welding not enter body to be welded, thinner body can be welded, and lengthen the body of a gun by cantilever support, thus there is enough intensity, can do long and not bend.The utility model can be 100 ~ 400mm and the long narrow tube inner wall of length≤8m by built-up welding diameter of bore, and owing to being connected with telescoping mechanism, working (machining) efficiency is high.
