As shown in Figure 1; A kind of programmable automatic welding system that present embodiment is described; It comprises material storage tube assembly 13, host backplane 10, feeding material component 11, piece-holder assembly 12, welding gun fixed mount 14, electric-control system, gas circuit and programmable controller; Described material storage tube assembly 13 comprises material storage tube 16; Above material storage tube assembly 13, be provided with the T type discharge oblique orbit 15 that a workpiece 9 gets into material storage tubes 16, the described material storage tube 16 anterior feeding ports 18 that connect a flare, crooked and influence the clamping of 12 pairs of workpiece of piece-holder assembly in the feeding process to prevent workpiece 9; Said material storage tube 16 is connected with feeding material component 11.Described feeding material component 11 includes feeding base plate 37; Feeding material component 11 is fixed on the host backplane 10; Both sides are provided with a feeding slide rail 39 with square breach respectively; The fixing respectively feeding slide plate 41 of feeding base plate 37 two bottom sides, feeding slide plate 41 is slidingly matched with described feeding slide rail 39, can insert front and back slip in the slide rail 39.On feeding base plate 37, be fixed with two workpiece locating pieces 36; In order to the position of fixation workpiece 9, workpiece locating piece 36 can be a L type structure, on workpiece locating piece 36, is provided with a plurality of slotted holes; Can be by the size adjustment spacing of workpiece, to realize fixing to multiple different size workpiece.A feeding push pedal 35 is equipped with at feeding base plate 37 rear portions, and feeding push pedal 35 is connected with feeding cylinder 32; Feeding cylinder 32 is fixedly connected with host backplane 10 through two cylinder supports 33.When feeding cylinder 32 piston-advance, can promote feeding base plate 37 and advance, require the position thereby workpiece 9 sent into.Feeding push pedal 35 both sides respectively are provided with one and regulate bolt 34, the stroke distances of scalable feeding.
Described feeding cylinder 32 take up on the feeding slide rail 39 fixing respectively magnetic field near switch 42 and No. two magnetic fields near switch 40, in order to obtaining or to send signal, thereby control the switching-over work of electromagnetic valve of gas circuit; On gas circuit, be provided with feeding cylinder magnetic valve 6, gripper cylinder magnetic valve 61, welding gun cylinder solenoid valve 62, fixing protective baffle plate 38 in feeding slide rail 39 the place aheads.
Advance when putting in place when feeding push pedal 35, touch No. two magnetic fields near switch 40 magnetic fields, produce a signal and make 61 switching-overs of gripper cylinder magnetic valve, gripper cylinder 54 air inlets promote piston-advance.Being provided with a magnetic field near feeding cylinder 32 1 sides near switch 42, when feeding cylinder 32 pistons are return the home position, touch a magnetic field near switch 42, can make 6 switching-overs of feeding cylinder magnetic valve, feeding cylinder 32 pistons are pushed away forward once more.
A piece-holder assembly 12 is arranged on feeding material component 11 the place aheads, and is connected with frame bottom plate 10.Clamp assemblies 12 has robot base 46 and manipulator cover plate 53; Both sides have a cushion block 49 respectively, form the box-like of hollow, and it is middle with manipulator cover plate 53 that the clamping manipulator 50 of an X type is arranged on robot base 46; Articulate through pin 47 and robot base 46 and manipulator cover plate 53; The manipulator front portion is provided with two V-type chucks 501 that opening is relative, applicable to the workpiece of clamping circular cross-section, to the section bar of different cross section; Chuck can make respective shapes into, to be suitable for the workpiece in different cross sections.Manipulator 50 both sides afterbodys articulate a mechanical arm 51 respectively through pin; Two arm 51 afterbodys are connected; Articulate through pin 48 with another pushing block 52 simultaneously, pushing block 52 is connected with gripper cylinder 54, and gripper cylinder 54 is fixed on the host backplane 10 through fixed support 56.When cylinder 54 piston-advance,, drive manipulator 50 around pin 47 rotations, the distance of progressively dwindling two V-type chucks 501, thereby clamping work pieces 9 through promoting pushing block 52 and mechanical arm 51.A magnetic field induction is equipped with near switch 55 in rear portion, clamp assemblies 12 top, contacts with pushing block 52, when manipulator 50 clamping work pieces 9; Pushing block 52 advances, and leaves near switch 55, produces a signal and makes magnetic valve 62 switching-overs; Promote welding gun cylinder 20 pistons and return downwards, thus beginning electric welding work.
Feeding material component outer cover 3, clamp assemblies outer cover 4 and welding job district outer cover 5 are arranged with feeding material component 11 respectively; Clamp assemblies 12 and welding job district cover; Protection equipment is not decreased ring by foreign object on the one hand; On the other hand, the arc light when also having covered welding, thus protection operator eyes can not stabbed by arc light.
Described programmable controller and magnetic field are connected near switch 55 and feeding cylinder magnetic valve 6, gripper cylinder magnetic valve 61, welding gun cylinder solenoid valve 62 near switch 40, No. three magnetic field near switch 42 and No. two magnetic field; And be connected with the wire feed switch of gas shielded welding machine; Through in programmable controller PLC, writing control action and time-program(me), the action of commander's whole system.
Automatic control journey of the present invention is accomplished by PLC, and three are carried out signals collecting near switch and turn back to PLC, press program setting and the delay adjustments of PLC, and the action of commander's magnetic valve and welding machine is like Figure 16.
Use is following:
The state of Figure 14-1 when not starting, feeding cylinder 32 pistons are retracted position, feeding push pedal 35 with contact near switch 42, promptly effective near switch 42; Gripper cylinder 54 pistons are in retracted position, pushing block 52 with contact near switch 55, promptly effective near switch 55, manipulator 50 is an open mode; Welding gun cylinder 20 pistons leave workpiece for stretching out state with welding gun 25 jack-up.
When the starting device automatic transmission, magnetic valve 6 switching-over, feeding cylinder 32 piston-advance are shifted workpiece 9 onto and are required the position.Like Figure 14-2
Feeding cylinder 32 piston-advance put back feeding push pedal 35 in place near switch 40 contacts, and are promptly invalid near switch 42, effective near switch 40.PLC receives after this changes, and produces a corresponding signal, makes magnetic valve 61 switching-overs of gripper cylinder 54, and piston is released, and promotion pushing block 52 also makes manipulator 50 clamping work pieces 9, like Figure 14-3.
This moment pushing block 52 with break away near switch 55, promptly invalid near switch 55.This moment, the PLC internal counter picked up counting, and treated in the program that the scheduled time sends signal to back PLC, produced a signal; Make magnetic valve 6 switching-overs, feeding cylinder 32 piston-retraction, this moment, workpiece 9 was clamped can and then not retreated; Again through scheduled time rear electromagnetic valve 62 switching-over, welding gun cylinder 20 piston-retraction, the welding gun fixed mount 14 of welding gun 25 that spurred clamping; With welding gun 25 workpiece 9 that furthers; Simultaneously PLC sends signal to welding machine and makes welding gun 25 begin to see off welding wire, after welding wire touches workpiece 9, begins welding, like Figure 14-4.
In the program that PLC finishes in advance with the time set of welding a suitable scope, after having arrived weld interval, send signal and make magnetic valve 62 switching-over, welding gun cylinder 20 boosts welding gun 25 and leaves workpiece, and stops wire feed, thereby stops electric welding.Like Figure 14-5.
After welding is accomplished through scheduled time gripper cylinder 54 piston-retraction; At this moment manipulator 50 its drives are unclamped workpiece 9 down, and the workpiece 9 that welds afterwards can directly fall down in the material spilling hole from host backplane 10 101; Take on container, or directly fall on conveyer belt, to flow to next procedure.State when this moment, equipment state was got back to unstart is again prepared operation cycle next time.Like Figure 14-6.
Whole duty transforms figure like Figure 17.
