Downside, lower end withstands on look nut 11, connects pressure regulation stud 1 below look nut 11, connects linear axis bottom pressure regulation stud 1
Holding 10, linear bearing 10 is fixed on bottom plate 9, and main shaft 17 is through linear bearing 10 and bottom plate 9.
Described four means of spot welds mechanisms include that capillary fixture 7, capillary fixture 7 are provided with the fixture screw for fixing capillary 18
6, capillary fixture 7 is slidably connected with relaying fixture 8 by chute, capillary fixture 7 is additionally provided with the chute for location and fixes spiral shell
Silk 16, main shaft 17 connects relaying fixture 8 through retainer 5, and retainer 5 is provided with screw 4, and by screw 4 clamping spindle 17,
Retainer 5 is slidably connected with the axis of guide 2 by little bearing 3.
Described bottom plate 9 uses insulation high-temperature-resistant material, the most indeformable.
Described circuit board 14 is provided with relay indicating light.
Described relay indicating light includes red light emitting diodes and green emitting diode.
The minimum centers-distance of relative two described capillaries 18 is 4mm.
Described look nut 11 uses double nut standby tight on main shaft 17, prevents owing to nut loosening causes pressure to diminish.
Pressure regulation stud 1 is screwed on four main shafts 17, and main shaft 17 is through linear bearing 10, it is ensured that axle exists
Axially being not fall off, linear bearing 10 is fixed on bottom plate 9.Owing to four main shafts 17 are not the most fixed, so
Clamped by retaining clip 5 and main shaft 17, by fixed guide axle 2, fixed angle can ensure that main shaft 17 will not radial rotary, with
Time can be slided up and down smoothly by little bearing 3 and the slip of the axis of guide 2, main shaft 17.
Being sliding groove structure between fixture 7 and relaying fixture 8, bottom is screwed.Relaying fixture 8 is screwed
On main shaft 17, can rotate with main shaft 17 and change the anglec of rotation.
Being provided with spring 12 between pressure regulation stud 1 and look nut 11, the upper end of spring 12 withstands on the downside of upper mounted plate 13, bullet
The lower end of spring 12 withstands on above look nut 11, and so when static, spring 12 has had pressure, when four main shafts 17 are whole

Clamped by screw 4 between retaining clip 5 and main shaft 17, and realize two merits by little bearing 3 and the axis of guide 2
Can, one is that the direction of rotation that can realize main shaft 17 is fixed, and two is that main shaft 17 can slide up and down smoothly, and the axis of guide 2
Between friction realized by the rotation of little bearing 3, this mode frictional force can be the least, reduces between all parts
Frictional dissipation.According to the size of welding workpiece, by the loosened screw of retaining clip 5, adjust the direction of rotation of four main shafts 17 simultaneously,
That is, make to swing bottom main shaft 17 certain angle, make the angle of capillary 18 adjust therewith, the solder joint of four capillaries 18 structure as required
Become square, rectangle or trapezoidal, fix the screw 4 of retaining clip 5 after adjusting, thus fix the relative position of capillary 18, full
The welding requirements of foot workpiece to be welded to difformity.
Pressurization adjusts and is screwed on main shaft 17 between stud 1 and main shaft 17, regulates bullet by adjusting nut 11
The decrement of spring 12, when welding workpiece, owing to four main shafts 17 are separate, when completing four nuggets, each nugget
Welding effect there will be different results, in order to ensure welding effect, need regulate pressure, rotating adjusting nut 11, make bullet
Spring 12 compresses, and when original state, spring 12 has had elastic force, so when four main shafts 17 compress downwards simultaneously, and capillary 18
Pressure has been had, it is ensured that at the move distance set, welding effect can reach requirement when butt-welding fitting just contacts.Due to
Soldering tip is in the state of working long hours, and in order to ensure that look nut 11 will not loosen, uses double nut standby tight here, prevent due to
Nut loosening causes pressure to diminish.
Due to soldering tip operationally, being in long-time discharge condition, electrode holder can generate heat, in order to ensure four electrodes it
Between be insulation, ensure when temperature is too high simultaneously, relative position between four capillaries 18 keeps constant, and this requires lower fixing
Plate 9 is a kind of high temperature resistant and the material of insulation, and the material of bottom plate 9 just disclosure satisfy that and will not deform at high operating temperatures and absolutely
The performance of edge, and the quality of bottom plate 9 is very light, and intensity can reach the intensity of aluminium alloy, and this is for ensureing that precision is wanted
The welding asked is that good material selects.
Between circuit board 14 and triggering screw 15, trigger screw 14 and be fixed on the upper end of four main shafts 17, when operating, four
When root bead pin 18 is pressed in workpiece, main shaft 17 can move up, and drives triggering screw 15 to trigger circuit board 14, makes the source of welding current put
Electricity.Must simultaneously meet four triggering screws 15 and trigger circuit board 14 simultaneously, just can realize discharging function, single main shaft 17 touches
Send out or several triggering therein, electric discharge phenomena will not be realized, each station green emitting when individually triggering, on circuit board 14
Diode can be bright, only triggers at four main shafts 17 simultaneously, and four green diode just can be gone out, red light emitting diodes just meeting
Bright, the most just can realize discharging function.
One welder described in the utility model is connected with automation equipment, can realize while one side 4 from
Dynamicization is welded, and is connected with automation equipment by two welders described in the utility model, while can realizing at two-sided 4
Automatic welding.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and modification, these change
Enter and also should be regarded as protection domain of the present utility model with modification.
