Abstract
The invention provides a welding head for a small-diameter cylinder. By using the welding head, when a longitudinal circumferential weld inside the small-diameter cylinder is welded, the quality of the circumferential weld can be ensured, and the labor strength of workers also can be relieved. The key point of the structure of the welding head is that: an upper guide pulley is arranged at the upper end of a wire feed roll fixing plate, an a lower guide pulley is arranged at the lower end of the wire feed roll fixing plate; an insulating bush wheel and a clamping wheel are arranged between the upper guide pulley and the lower guide pulley to feed or withdraw welding wires; the insulating bush wheel is driven to rotate by a reducing motor; the running tangential line of the wire feed reducing motor is equidirectional with the welding wires; and a welding gun clamping block and a welding gun fixing block are arranged at lower ends of the wire feed roll fixing plate and the lower guide pulley and are used for connecting and fixing a welding gun. When the welding head is used, the welding wires enter a driving unit formed by the insulating bush wheel driven by the wire feed reducing motor and the clamping wheel from the upper guide pulley, and enter the welding gun from the lower guide pulley by the motion of the reducing motor.
Description
Technical field:
The present invention proposes to be suitable for the welding head of minor diameter cylindrical shell, relates to a kind of metal solder device, particularly the welding head of the submerged-arc welding manipulator of Φ 300-Φ 600 minor diameter cylindrical shells.
Background technology:
At present, many boilers and pressure vessel manufacturer when the vertical circumferential weld of welding Φ 300-Φ 600 minor diameter inner barrel, because the welder head volume of common submerged-arc welding is bigger, can't stretches into inner barrel and implement submerged arc welding.Cause many producers to use manual welding instead, increased working strength of workers so greatly, also be difficult to guarantee welding quality to be easy to generate weld defect, problem such as weld seam is defective.
Summary of the invention:
The welding head (being called for short head once) that the purpose of this invention is to provide a kind of submerged-arc welding manipulator of Φ 300-Φ 600 minor diameter cylindrical shells, use this head, during the vertical circumferential weld of welding Φ 300-Φ 600 minor diameter inner barrel, can guarantee weldquality, can alleviate working strength of workers again, realization submerged-arc welding is welded automatically, increases work efficiency.
Technical scheme of the present invention is such: it mainly comprises the welding head of minor diameter cylindrical shell: go up directive wheel, pinch wheels, following directive wheel, wire feed rolls fixed head, insulation wheel, reductor Connection Block, wire feed reducing motor, welding gun, welding gun clamp, welding gun fixed block, connecting plate, clamping adjustment handwheel.Its structural feature is: establish directive wheel in wire feed rolls fixed head upper end, directive wheel is set in the lower end, establish insulation wheel and pinch wheels between the two, insulation wheel and pinch wheels rely closely, pinch wheels is adjusted handwheel adjustment position with it by clamping, work to clamp welding wire, to send welding wire or backstep welding silk, the insulation wheel is located at wire feed reducing motor front end, is driven by reductor and rotates, and wire feed reducing motor running tangent line and welding wire for submerged-arc welding are in the same way, the wire feed reducing motor is fixed on the wire feed rolls fixed head by the reductor Connection Block, the welding gun clamp is established behind the following directive wheel in the lower end of wire feed rolls fixed head, the welding gun fixed block is in order to be connected and fixed welding gun; When using this device, welding wire enters the driver element of being made up of the insulation wheel and the pinch wheels of the driving of wire feed reducing motor by last directive wheel, and the motion by reducing motor is entered in the welding gun by following directive wheel then.
Advantage of the present invention is, has dwindled the welder head volume of common submerged-arc welding greatly, makes it can stretch into the minor diameter inner barrel and implements submerged arc welding.
