The purpose of this utility model provides the light-duty welding machine of a kind of convenient adjusting, energy balance fixed-piping.
The utility model adopts following technical proposal: a kind of portable pipeline automatic welding machine, comprise main frame, the source of welding current, welding control system and wire feeder, main frame comprises support, roller, extension spring, steel pipe crossbeam and loam cake, loam cake is set on the support, support one side vertically is provided with a steel pipe, the steel pipe top connects the steel pipe crossbeam, welding control system and wire feeder are set respectively on the steel pipe crossbeam, the vertically parallel second wheel that is provided with on support, roller top horizontally set two chains, between roller and chain, leave the space of fixing pipeline to be welded, one end of chain is fixed in loam cake on one side, and the chain other end connects an extension spring by the hook of chain hook connection extension spring on the another side support, be covered with chain tensioner on the extension spring relative edge, chain tensioner tilts to press the outside of chain.
The utility model adopts roller rotation, the relatively-stationary mode of welding head to realize automatic welding, and control system wherein is used to control welding parameter, swing parameter, roller rotating speed etc.When pipeline to be welded is longer, use the supporting dolly of welding machine (optional components) to cooperate with roller set on the main frame, jointly soldered pipeline is supported on the horizontal plane, make soldered pipeline smooth rotation, the suffered moment of flexure minimum of while welding machine.
In the technical program, the roller top also can only be provided with the fixing pipeline to be welded of one group of chain.
Described chain tensioner is, described chain tensioner is, offer a screwed hole last covering, spiral shell welds a clamp nut in the screwed hole, the clamping screw that is spirally connected in the clamp nut, the clamping screw upper end is provided with handwheel, clamp nut lower end snail cock wheel seat, wheel seat connects contact roller by wheel shaft, and contact roller presses the chain outside.Large roller diameter on the chain is greater than the carrier bar width, on the chain only large roller can with the tube contacts to be welded of being fixed, chain can be rolled on the pipeline to be welded, therefore, be rolling friction between chain and the pipeline to be welded, but not sliding friction, purpose is the frictional force that reduces between chain and the pipeline to be welded, the convenient adjusting.
In order to control the rotating speed of roller well, also be provided with reductor on the described main frame and be connected with roller.
Described chain hook is by rising to the bait and following hook is formed, and rising to the bait is connected with chain, promptly rises to the bait and colludes between the chain link of chain, and following hook is connected with the hook of extension spring.
The rising to the bait of described chain hook can be inserted in the gap between any chain roller pitch, hooks chain, regulates as required, will rise to the bait and insert in position.
Advantage of the present utility model shows following aspect: one, adopt chain tensioner tension chain, the convenient adjusting and use; Two, the source of welding current and wire feeder are selected approved product for use, can be selected voluntarily by the client, have realized good coupling; Three, chain tensioner adopts the adjustable diameter and screw adjusting mode, can finely tune, and makes that adjusting is more accurate; Four, an end of chain is connected with extension spring, makes chain thrust the right and left balance.Five, simple in structure, complete machine is in light weight, conveniently moving.
