Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Fig. 1 shows the present embodiment spot-welded systematic difference schematic diagram, with reference to diagram, this spot-welded system comprises: be arranged on the suspension spot welding machine 13 on the crossbeam of workshop, be arranged on the tooling platform 16 on welding post, for placing workpiece 17 to be welded on tooling platform 16, described tooling platform 16 is made up of conductive material; The spot-welding gun 18 be connected with described suspension spot welding machine 13, described suspension spot welding machine 13 is for powering for described spot-welding gun 18; And the earth connection 15 that two ends are connected with suspension spot welding machine 13 and tooling platform 16 respectively.The spot-welded system that this structure is formed, based on the original suspension spot welding machine 13 arranged of workshop welding post as power supply, for spot-welding gun 18 is powered, the triviality that workshop body in white plants nail welding system layout can be simplified, reduce the cost required for welding system layout; A loop is formed by between suspension spot welding machine 13, spot-welding gun 18, workpiece 17 to be welded, tooling platform 16 by earth connection 15, when the surface that spot-welding gun 18 contacts workpiece 17 is welded, meet the single fillet welded requirement of workpiece 17, realize good spot welding and plant nail.
Particularly, as shown in Figure 2, spot-welding gun 18 comprises the structural representation of described spot-welding gun 18: water flowing torch head 1, and its one end arranges welding gun electrode 10, the inner Water cooling cable 7 through being connected with described welding gun electrode 10; Handle 4, fixing described water flowing torch head 1 on it, described handle 4 is arranged the switch 5 be connected with described suspension spot welding machine 13, described switch 5 is connected by control line 6 with described suspension spot welding machine 13.The conveniently fixed installation of spot-welding gun 18 on handle 4, described handle 4 arranges handle hoop-closing buckle 2, and described water flowing torch head 1 is fixed on described handle hoop-closing buckle 2.
The spot-welding gun 18 of the present embodiment is also carry out transforming obtaining based on the structure of suspension spot welding machine welding gun, can reduce the cost of the present embodiment spot-welded system further.Particularly, water flowing torch head 1 is taken out from suspension spot welding machine soldering turret, then handle 4 is taken off equally; Handle 4 is buckled 2 by fastening bolt 3 with handle clip and is fixedly connected with, and handle clip button 2 is fixed by fastening bolt and water flowing torch head 1 equally, requires to insulate preferably above the tube wall of water flowing torch head 1 and between handle clip button 2.Switch 5 is as a whole with handle 4, and first control line 6 one end is connected on the switch 5 of handle 4, then other one end is connected to suspension spot welding machine 13.By easy transformation, can obtain the basic frame structure of spot-welding gun 18 and supply electrical connection, the operation of switch 5 is passed to suspension spot welding machine 13 by control line 6, and suspension spot welding machine 13 can be powered to Water cooling cable according to this information, to weld.
In the present embodiment, earth connection 15 makes workpiece 17 self as the part in loop, makes welding process define closed loop, meets the condition needed for spot-welded; Described earth connection 15 self can meet the loading demands under welding condition completely.
Described suspension spot welding machine 13 is also provided with water flowing/backwater module, the delivery port of described water flowing/backwater module is connected with described Water cooling cable 7; The water inlet of described water flowing/backwater module is connected by return pipe 11 with the returning pipe joint 8 be arranged on described Water cooling cable 7; Described suspension spot welding machine 13 is also provided with control module, described control module is connected respectively with described water flowing/backwater module, Water cooling cable 7 and control line 6, controls described water flowing/carry out water flowing or backwater between backwater module and Water cooling cable 7 and control suspension spot welding machine 13 whether powering to described Water cooling cable 7 with the signal transmitted according to control line 6.In the present embodiment, welding gun electrode 10 can play the effect of water inlet pipe in Water cooling cable 7 inside, defines good circulation simultaneously, and then reach the object of cooling with return pipe 11.
Described welding gun electrode 10 end is also provided with welded limiting platform 9, to carry out spacing to nail of planting to be welded, ensures that welding is efficiently accurately carried out.
Tube connector wire harness between spot-welding gun 18 and suspension spot welding machine 13 at least comprises above-mentioned Water cooling cable 7, control line 6 and return pipe 1, this bale of pipeline has certain length and weight, when operative employee 14 carries out planting nail welding, if directly operate spot-welding gun 18 by dragging above-mentioned bale of pipeline, labour intensity will be very large, so described bale of pipeline is connected with the balancer 12 be arranged on the crossbeam of workshop in the present embodiment, described workshop crossbeam is provided with at least two balancers 12, two described balancers 12 position corresponding on described bale of pipeline connects, balancer 12 can either carry the weight of bale of pipeline, can ensure that again the balance and stability of bale of pipeline moves, convenient operation work 14 plants nail welding accurately.
When carrying out planting nail welding, first according to the using state figure shown in Fig. 1, above-mentioned indirect welding welding system is installed, the fastness of Water cooling cable 7 and earth connection 15 must be guaranteed during installation, any loosening can not be had, otherwise explosion and obvious spark when implementing welding, can be produced.After whole system installs, first the adjustment of welding parameter is carried out, for ensureing that spot-welding gun 18 is energized after first contacting workpiece 17, need to arrange welding squeeze time to be not less than 15 cycles (frequency is the electric current of 50 hertz, a cycle equals 0.02 second), be not less than 15 cycles pressing time, in this welding, the object of the hitch point welding machine that precompressed and pressing time are complete and common is different, and these two parameters mainly guarantee that welding gun is that workpiece 17 is not energized temporarily at contact plate or gentle touchdown plate here.Spot-welding gun 18 welding parameter is mainly carried out to the setting of weld interval and welding current, ordinary circumstance is set as 30 cycles weld interval, and welding current is at 8000A.
When coming into effect welding, first earth connection 15 is pressed on when tooling platform 16 guaranteeing work and forms good loop, then workpiece 17 is put on tooling platform 16, guarantee the contact surface that can have certain area between tooling platform 16 and workpiece 17, more guarantee current loop when welding.The same with welding habitually in the past when formal enforcement welding, first the greasy dirt etc. on workpiece 17 is disposed, and then implement welding, finally reach the effect that one side plants nail.Spot-welding gun 18 requires that in the process of operation welding gun electrode 10 contacts with workpiece 17 and applies certain external force.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
