Detailed description of the invention
Below in conjunction with accompanying drawing 1-3, the present invention will be further described: four-point welder, including main body 2 13 and the triggering system being located thereon, described triggering system Bonding pressure regulation device, pressure controlling device connects four means of spot welds mechanisms, described pressure controlling device is between main body 1 and main body 2 13, and four means of spot welds mechanisms are positioned at below main body 1.
Described triggering system includes the circuit board 14 of two pieces of series windings, and every piece of circuit board 14 is respectively equipped with the optical coupled switch of two series windings, and each optical coupled switch is respectively arranged below with one and triggers screw 15, and four are triggered screw 15 and connect four main shafts 17 respectively.
Described pressure controlling device includes the spring 12 being arranged on main shaft 17 periphery, spring 12 upper end withstands on the downside of main body 2 13, lower end withstands on look nut 11, look nut 11 is connected below pressure regulation stud 1, linear bearing 10 is connected bottom pressure regulation stud 1, linear bearing 10 is fixed in main body 1, and main shaft 17 passes linear bearing 10 and main body 1.
Described four means of spot welds mechanisms include capillary fixture 7, capillary fixture 7 is provided with the fixture screw 6 for fixing capillary 18, capillary fixture 7 is slidably connected with relaying fixture 8 by chute, capillary fixture 7 is additionally provided with the chute fixed screw 16 for positioning, main shaft 17 connects relaying fixture 8 through retainer 5, 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 main body 1 adopts insulation high-temperature-resistant material, indeformable at high operating temperatures.
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 adopts double nut standby tight on main shaft 17, it is prevented that owing to nut loosening causes that pressure diminishes.
Pressure regulation stud 1 is screwed on four main shafts 17, main shaft 17 traverse linear bearing 10, it is ensured that axle is axially being not fall off, and linear bearing 10 is fixed in main body 1.Owing to four main shafts 17 are not fixed diametrically, so being 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, simultaneously by the slip of little bearing 3 and the axis of guide 2, main shaft 17 can slide up and down smoothly.
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.
Spring 12 it is provided with between pressure regulation stud 1 and look nut 11, the upper end of spring 12 withstands on the downside of main body 2 13, the lower end of spring 12 withstands on above look nut 11, so when static, spring 12 has had pressure, when four main shaft 17 entirety are axially upwardly moved, the decrement of spring 12 can become big, and pressure also can increase.
Circuit board 14 and triggering screw 15, when four main shafts 17 move upward, the pressure of spring 12 reaches setting value, it is necessary to electrode discharge, in order to provide discharge signal, triggers screw 15 position and reaches the optical coupled switch of circuit board 14, make closing of circuit, provide discharge signal.
Fixed by chute connected mode between fixture 7 and relaying fixture 8, this connected mode can ensure that relaying fixture 8 is fixed, fixture 7 can only slide in the chute of relaying fixture 8, being limited in required accuracy rating by relative positional accuracy therebetween of this simple structure.In four spot welding heads, there are four pairs of independent this structures, it is possible to regulate relative two fixtures 7 and clamp the centre-to-centre spacing of capillary 18.Minimum centers-distance can reach 4mm, this front and back regulate achieve this function can suitable for multiple sizes workpiece welding.
Clamped by screw 4 between retaining clip 5 and main shaft 17, and realize two functions by little bearing 3 and the axis of guide 2, one is that the direction of rotation that can realize main shaft 17 is fixed, two is that main shaft 17 can slide up and down smoothly, with the friction between the axis of guide 2 is realized by the rotation of little bearing 3, this mode frictional force can be very little, reduces the frictional dissipation between all parts.Size according to welding workpiece, loosened screw by retaining clip 5, adjust the direction of rotation of four main shafts 17 simultaneously, that is, make swing certain angle bottom main shaft 17, make the angle of capillary 18 adjust therewith, the solder joint of four capillaries 18 constitutes square, rectangle or trapezoidal as required, fix the screw 4 of retaining clip 5 after adjusting, thus the relative position of fixing capillary 18, meet the welding requirements to difformity workpiece to be welded.
Pressurization adjusts and is screwed on main shaft 17 between stud 1 and main shaft 17, the decrement of spring 12 is regulated by adjusting nut 11, when welding workpiece, owing to four main shafts 17 are independent from, when completing four nuggets, the welding effect of each nugget there will be different results, in order to ensure welding effect, need to regulate pressure, rotating adjusting nut 11, spring 12 is made to compress, when original state, spring 12 has had elastic force, so when four main shafts 17 compress downwards simultaneously, capillary 18 butt-welding fitting has had pressure when just contacting, can ensure that at the move distance set, welding effect can reach requirement.Owing to soldering tip is in the state of working long hours, in order to ensure that look nut 11 will not loosen, adopt double nut standby tight here, it is prevented that owing to nut loosening causes that pressure diminishes.
Due to soldering tip operationally, it is in long-time discharge condition, electrode holder can generate heat, in order to ensure between four electrodes it is insulation, ensure when temperature is too high simultaneously, relative position between four capillaries 18 remains unchanged, this requires that main body 1 is a kind of high temperature resistant and insulation material, the material of main body 1 just disclosure satisfy that the performance that will not deform and insulate at high operating temperatures, and the quality of main body 1 is very light, intensity can reach the intensity of aluminium alloy, and this is for ensureing that the material that the welding of required precision is good selects.
Between circuit board 14 and triggering screw 15, triggering screw 14 and be fixed on the upper end of four main shafts 17, when operating, when four root bead pins 18 are 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 discharge.Must simultaneously meet four triggering screws 15 and trigger circuit board 14 simultaneously, just can realize discharging function, independent main shaft 17 triggers or several triggering therein, will not realizing electric discharge phenomena, when individually triggering, each station green LED on circuit board 14 can be bright, only trigger at four main shafts 17 simultaneously, four green diode just can be gone out, and red light emitting diodes just can be bright, at this moment just can realize discharging function.
One welder of the present invention is connected with automation equipment, it may be achieved automatic welding while one side 4, two welders of the present invention are connected with automation equipment, it may be achieved automatic welding while two-sided 4.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
