On, main shaft is divided into main shaft interlude and both ends, and main shaft both ends are mounted on bearing block, connects decelerating motor and master with shaft coupling
Left section of axis, and the revolving speed of motor is adjustable, is separated among shaft coupling with insulator, insulator is to prevent the electricity in reflow process
It spreads and passs motor, right section of fit on mercury slip ring of main shaft；Main shaft both ends and main shaft interlude are separated with mica sheet makes both
Be not directly contacted with, and with nut be bolted；Workpiece is fixed on main shaft interlude, and welding gun is fixed on main shaft interlude
Surface, mercury slip ring connects source of welding current anode, and welding gun connects source of welding current cathode.
With the method for the device remelting workpiece: motor is opened, by workpiece surface linear velocity, welding current, welding gun and workpiece
Distance, argon gas flow velocity, remelting together after translation distance adjust to optimal value, can be to circular ring work piece surface after welding gun striking
Carry out re melting process, after striking main shaft rotate a circle i.e. workpiece remelting together, power off at this time, by welding-torch horizontal translate one section away from
Continue remelting from, energization striking, and so on can be by workpiece by road whole remelting.Remelting is carried out using this heat source of argon arc
The patent of method forefathers had it is involved, why select argon arc make heat source carry out re melting process be because argon arc equipment just
Preferably, simply, and argon arc remelting has argon gas protection, the oxidation on surface when can prevent workpiece remelting.
The working mechanism of the utility model are as follows: argon arc belongs to electric arc, therefore the positive and negative anodes of the source of welding current must be when remelting
Conduct, and electric current will stabilization cannot power off or become smaller or larger, and workpiece rotates together with main shaft when present apparatus remelting, weldering
Rifle connects source of welding current cathode, and according to current design, either workpiece or main shaft connects source of welding current anode, can all cause to weld
The conducting wire of positive pole follows main shaft or workpiece rotation so as to cause conducting wire winding；Mercury slip ring is divided into left end (round end) and right
It holds (fixing end), and there is threaded binding post at both ends, and both ends can rotate freely and conduct, and electric current is steady,
Therefore the binding post of mercury slip ring left end directly can be screwed into right section of main shaft, right end binding post connects source of welding current cathode, this
Mercury slip ring left end follows main shaft to rotate when sample one carrys out remelting, and the right end for connecing source of welding current cathode does not rotate, therefore will not lead
Conducting wire winding is caused, to form following welding circuit when remelting: welding cathode power supply line → welding gun → workpiece → main shaft interlude
Right section of → main shaft → mercury slip ring → welding anode power cord.
The present invention once load and unload can 5 workpiece of remelting, this significantly improves working efficiency, and the workpiece surface ten after remelting
It is divided bright, intermittent situation does not occur in remelted layer, and due to there is argon gas protection in reflow process, remelted layer does not occur sternly
The oxidative phenomena of weight.
The above, only one embodiment of the utility model additionally include directly carrying out to metal ring workpiece
Remelting, and the circular ring work piece that externally circular surfaces are coated with metallic paint carry out Argon arc cladding, but the protection scope of the utility model
Be not limited thereto, anyone skilled in the art within the technical scope disclosed by the utility model, according to this
Technical solution and its utility model design of utility model are subject to equivalent substitution or change, should all cover in the utility model right
It is required that protection scope within.
The utility model unaccomplished matter is well-known technique.
