Description

Small electrode holder for soldering and point-welding

The utility model discloses a kind of small-sized soldering, the dual-purpose electrode holders of spot welding, belongs to electric welding tool kind.

So far, in middle-size and small-size copper conductor resistance brazing, existing soldering turret is only made soldering usefulness, is not with microswitch, needs during soldering with floor push control, and is very inconvenient.When soldering finished, rubescent graphite electrode easily comes off from electrode holder, and was dangerous.Simultaneously, electrode holder is made with weldering arm one body and function steel and iron parts, and resistance is big, and heating is serious; Soldering turret two handles are swaged into back overcoat insulation tube with steel part, do not have reed between handle, and armrest moves clamping electrode, effort, inconvenience.Its cable adopts general electric welding machine Plastic-sheathed Cable, easily aging, cracking, and any processing is not done on the cable connector surface that links to each other with soldering turret, oxidation easily.In addition, existing soldering turret is each factory's self-control, and outward appearance is relatively poor.

The purpose of this utility model provides a kind of and soldering, the supporting use of the dual-purpose electric welding machine of spot welding, can carry out soldering or spot welding, welding efficiency height, welding quality are good, the dual-purpose electrode holders that function is many, in light weight, easy to operate and safe and reliable.

Task is finished like this: two electrodes 1 insert respectively and constitute upper and lower jaw in the hollow electrode folder 2, on weld arm 3 and weld 9 on arm down and be with rotating shaft 12 and be movably hinged, upper handle 7 afterbodys are equipped with microswitch 8.Electrode holder 2 be pressed into respectively the weldering arm 3, down weld arm 9 after, fixing with lock-screw 14,10 of upper handle 7 and lower handles are equipped with reed 6, the material of electrode 1 is divided into two kinds: during soldering, use graphite electrode, use copper alloy electrode during spot welding, under weld arm 9 and 4 on the support insulation board 5 of packing into, the high temperature-resistant cable joint 11 after surface treatment is threaded with upper and lower weldering arm 3,9 sides.Angle is 110 ° when welding current is soldering 350A, the spot welding 1000A left and right sides, between the electrode holder axis; When welding current was soldering 800A, the spot welding 3000A left and right sides, angle was 90 ° between the electrode holder axis.

After adopting said structure, after this soldering turret matches with welding machine, adopt graphite electrode to carry out resistance brazing, can replace oxygen one acetylene to carry out high temperature brazing, compare with the low temperature brazing (soldering) of adopting electric iron have the welding efficiency height, advantages such as Joint Strength is big, heatproof, soldering turret also can carry out low temperature brazing directly or indirectly as required.During spot welding, change graphite electrode, load onto high temperature resistant copper alloy electrode, connect welding machine, manual pressure, just can carry out spot welding less, thin steel-iron components.In Fig. 1 soldering turret, pull down after the rotating shaft 12 in two.After wherein mixing corresponding electrode, just can carry out soldering or spot welding separately, enlarge the welding scope with " half the soldering turret " of microswitch.Compare with existing soldering turret.The utlity model has the welding efficiency height, in light weight, function is many, easy to operate, welding quality good, advantage such as safe and reliable, is a kind of comparatively ideal electric resistance welding instrument.

Provide embodiment below in conjunction with accompanying drawing.

Figure 12 has the soldering turret structural representation now.

Remainder among the figure, 4 is support, and 13 is workpiece, and 14 and 15 is lock-screw.Electrode holder 2 usefulness heat-resisting cast iron are made, and upper and lower weldering arm 3,9 usefulness brass are made.Upper and lower handle 7,10 usefulness heat resistant glass cloth rods are made, after the weldering arm is threaded, with lock-screw 15 lockings.When welding current is soldering 350A, spot welding 1000A, use KWX type microswitch; When welding current is soldering 800A, spot welding 3000A, use KW2-1 type microswitch, the copper alloy electrode during spot welding is a chromium zirconium copper electrode, the material of rotating shaft 12 is a metalwork, can remove.Insulation board 5 is to prevent short circuit usefulness, reed 6 is used for clamping and fixing welding work pieces, rely on the reed holding workpiece during soldering, except that holding workpiece, the also necessary upper and lower handle of manual control produces certain welding pressure during spot welding, weld, when less, thin steel-iron components was carried out spot welding, if adopt the button type spot welding of Fig. 6, Fig. 9, then effect was better.

The utility model varies in size according to welding current, is divided into " tong " and " small forceps " two kinds of specifications, and " tong " is welding current 3000A when 800A, spot welding when being soldering, and " small forceps " is welding current 1000A when being soldering 350A, spot welding." tong " electrode holder adopts the version of Fig. 7, Fig. 8, Fig. 9.Angle is 90 ° between its axis; Temperature is more better; " small forceps " electrode holder adopts the version of Fig. 1, Fig. 5, Fig. 6, and angle is 110 ° between its axis, its objective is the copper conductor and part and the assembling electrode that help the welding position anxiety.Two lead-out terminals on the single-phase welding machine are by two heat proof cables, upper and lower weldering arm on the soldering turret, and electrode holder, electrode and workpiece constitute welding circuit, by " microswitch " control welding " leading to ", " breaking " and weld interval on the soldering turret.
