Description

Electric welding tongs with internal clamping head

The utility model relates to and is used for welding, the clamping of soldering or local heat cut workpiece or the clamp of location.

At present, general manual electrode holders are that clamp-type outer spring thick stick weld clip is held welding rod, with bridge screw clamping power line.Its main drawback has: the operator will have big grip just can open the jaw dress to change welding rod.Continuous operation expends muscle power, particularly requires great effort when women welder or weakling are operated, and causes the tired operating efficiency that reduces easily; The soldering turret mouth is two-way charged, easily causes the jaw scaling loss, and soldering turret mouth guard shield is fragile, causes burn when making a jaw dew place contact work package, influences product quality, and power line tightens up with bridge screw, and frequent motion is loosening easily, causes soldering turret body self-heating cooking loss of energy.

CN902222112 thin plate electric welding machine electrode holder, by case, core, handle, spring and the throw-out collar etc. that compresses that has a groove are formed, utilize the spring compression throw-out collar to make the dislocation in core hole and case hole is clamped welding rod, this electrode holder welding rod clamping direction changes difficulty, be difficult for adapting to multidirectional various welding positions welding, the scope of application is less.

The purpose of this utility model is to provide a kind of novel soldering turret that overcomes above-mentioned soldering turret weak point.Welding rod clamping adjustable angle is whole, enlarge the soldering turret scope of application, and appropriate design prevents jaw discharge scaling loss, alleviates the soldering turret volume and weight and improves working conditions, and changes the power cable clamping structure, prevents loosening cutting down the consumption of energy, and prolongs soldering turret service life.

The utility model reaches by following approach: the soldering turret main body of the utility model soldering turret conduction places insulation protection head-shield and sleeve pipe insulated handle; welding rod clamping chamber (front portion) and cable taper surface clamping chamber (rear portion) are arranged in the soldering turret main body; welding rod clamping chamber is built-in with the right side, left electrode socket; tension force pressing clip head-clamp with the compression spring is held welding rod; when connecting chuck, can make the multidirectional adjusting welding of welding rod angle, have wide range of applications with spherical bearing.The welding rod right side (or left side) chuck is made of insulating materials, makes the chuck unilateal conduction, prolongs the soldering turret life-span.The electrode carrier mouth relevant position of full-enclosed insulation protection head-shield and soldering turret body front part has the perforation bellmouth orifice; be convenient to the welding rod clamping; being screwed into opening elastic nut (its front end conical surface post inner chamber shape mask has the clamping tooth) in the soldering turret back body cable taper surface clamping chamber, the cable that penetrates can be embraced wedge firm; be difficult for becoming flexible, be suitable for the welding of changeable orientation.

Effect of the present utility model is: be adapted to the Welding Structure welding of all places, owing to the chuck unilateal conduction, reduce or the discharge scaling loss when having avoided changing welding rod, can prolong soldering turret service life, full-enclosed insulation protection head-shield is difficult for breaking welding product and guarantees the weldment quality; Welding rod is clamped in uses compression spring inner clamping type in the soldering turret main body, volume is little in light weight, has alleviated labor strength, can boost productivity; Power line compresses the full bag of opening elastic nut by soldering turret main body dimension shape chamber and holds cable tightly, forms firmly to connect, and is difficult for looseningly, has reduced energy dissipation.

Fig. 1 is the electrode socket structure chart that the utility model has the sphere coupling seat;

Fig. 2, Fig. 3 the utlity model has monoblock type electrode socket structure chart.

The utility model in conjunction with the accompanying drawings in 1 embodiment details are as follows: felt pad ［ 7 ］, compression spring ［ 6 ］, pack into the successively anterior welding rod clamping of soldering turret main body ［ 8 ］ chamber of the spherical bearing ［ 2 ］ of having assembled the sphere insulation protective jacket ［ 5 ］ of the right chuck of insulation welding rod ［ 4 ］ and having assembled welding rod left side chuck ［ 3 ］, bounce with compression spring ［ 6 ］ compresses electrode socket, keep electrode socket ［ 3 ］, ［ 4 ］ chucking power between, have 1-4 road welding rod holding tank as A-A view clamping jaw, the welding rod holding tank can be wide, also can need make its size different according to the core diameter clamping, general clamp port radius is discard electrode size radius R, and notch subtracts 02 to 05 for R deeply; Again insulation protection head-shield ［ 1 ］ is fixed on outside the soldering turret main body ［ 8 ］ with screw thread, prevent the workpiece of burning when soldering turret contacts with workpiece, the folder mouth correspondence position of insulation protection head-shield ［ 1 ］ and soldering turret main body ［ 8 ］ and electrode socket ［ 3 ］ ［ 4 ］ has the loudspeaker through hole of perforation, be convenient to the welding rod clamping, be suitable for the adjustment of welding rod orientation angle; Opening elastic nut ［ 9 ］ is put into the conical surface cable clamping chamber of soldering turret main body ［ 8 ］, penetrate power cable, tighten opening elastic nut ［ 9 ］ and be about to cable and firmly hold tightly.At last sleeve pipe insulated handle ［ 10 ］ is sleeved on outside the soldering turret main body ［ 8 ］ and can uses for welding.

Its operation principle is: the welding rod head is inserted from the loudspeaker aperture, welding current reaches welding rod through conical surface opening elastic nut ［ 9 ］ by soldering turret main body ［ 8 ］ connection welding rod left side chuck ［ 3 ］ by power cable and forms the welding current path, because electrode socket ［ 3 ］, ［ 4 ］ equal seated connection are in spherical bearing, so can adjust welding rod welding angle arbitrarily, the moving welding rod that is held of only with hand plate gets final product, when a root bead bar uses up when changing welding rod, new welding rod can be extruded the remaining discard electrode jaw of packing into from jaw and can continue welding.
