Description

Gantry multiple-spot welder
Technical field
The present invention relates to a kind of resistance welder, relate in particular to a kind of gantry multiple-spot welder.
Background technology
The kind of resistance welder has a lot, and commonplace have single phase ac welding machine or a phase secondary rectification welding machine.This resistance welder is at the stainless steel material of welding 2Cr13Ni4Mn9 and have and but be not suitable for when strict process requires.Because workpiece material 2Cr13Ni4Mn9 stainless steel, its welding characteristic is: the big 50%-60% of welding electrode pressure ratio common stainless steel; This workpiece is a heat-radiator plate, and interior water-filling, pressure are at 20Mpa, so butt welding point is strict, can not has during welding and splash, and the nugget transition is even around the welding; Long 7600mm * the 1220mm of this heat-radiator plate has 1440 solder joints on the plate, become regular distribution, and requirement can not have a pad not reach quality requirement.Otherwise whole plate does to do over again processing.
Consistent single phase ac welding machine or the phase secondary rectification welding machine that adopts of traditional welding manner: all there is shortcoming in this this welding to this workpiece welding:
1.A, single phase ac electric resistance welding machine is big because of the welding circuit reactance, power factor has only about 40%, energy loss is big, and is not energy-conservation, uneconomical.B, required time of welding are long, and the heat affected area is big, and welding work pieces is easy to generate distortion.C, required time of welding are long, and it is long to conduct the hot time to peripheral metal, and heat loss is many, and general heat loss accounts for about the 30%-50% of total amount of heat, welds the heat great majority of generation and has done idle work.
2. the phase secondary rectification welding machine is output as direct current, but does not also have secondary constant-current control function at present, and whole plate of this workpiece has 1440 solder joints, and size of current is the same in the time of can not guaranteeing each solder joint welding like this.This is directly connected to the quality of solder joint.
3. traditional welding manner is single-point welding, carries out operation, and a plate welding is finished and needed about 30 minutes, and operating personnel need 3-4 people to operate to finish, and production efficiency is low like this, and personnel labor intensity is big.
Summary of the invention
Technical problem to be solved by this invention is exactly the defective that exists at existing resistance welder, and a kind of gantry multiple-spot welder is provided, and it has overcome big, the inefficient shortcoming of existing resistance welder energy loss.
Technical scheme of the present invention is achieved in that it comprises electrical control gear, spot welding hydraulic system and resistance welding machine, the both sides of resistance welding machine are fixed with front console and aftertable, it is characterized in that: all be fixed with longitudinal movement rail on front console and the aftertable, be fixed with horizontal traveling roller on the aftertable, the front end of front console and the tail end of aftertable are fixed with workpiece detent mechanism and servo-actuating device, and the both sides of front console and aftertable are fixed with a plurality of guiders.
The present invention's technical scheme preferably is: described resistance welding machine comprises upper spider and lower bearing bracket, corresponding on upper spider and the lower bearing bracket a plurality of welders is housed; Described welder comprises a welding oil cylinder, on the piston rod of welding oil cylinder electrode tip holder is housed, and welding electrode is housed on the electrode tip holder; Described guider comprises a fixed head, be fixed with accurate line slide rail on the fixed head, slide block is equipped with in activity on the accurate line slide rail, the slide block top is fixed with the guide securement plate, one end of guide securement plate is fixed with the orienting roll wheel shaft by the directive wheel fixed block, guide roller is equipped with in activity on the orienting roll wheel shaft, and the other end of guide securement plate is connected with the shift cylinder slurcam, and the shift cylinder slurcam is connected with the piston rod of shift cylinder.
The advantage that the present invention has is simple in structure, automaticity is high, it can realize that multiple spot welds automatically, the energy loss of comparing it with existing resistance welder is low, production efficiency is high, welding quality good.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
As shown in Figure 1, the present invention includes electrical control gear, spot welding hydraulic system and resistance welding machine, the both sides of resistance welding machine 1 are fixed with front console 2 and aftertable 3.All be fixed with longitudinal movement rail 4 on front console 2 and the aftertable 3 as shown in Figure 2, be fixed with horizontal traveling roller 5 on the aftertable 3, the front end of front console 2 and the tail end of aftertable are fixed with workpiece detent mechanism 6 and servo-actuating device 7, and the both sides of front console 2 and aftertable 3 are fixed with a plurality of guiders 8.Described as shown in Figure 3 resistance welding machine 1 comprises upper spider 9 and lower bearing bracket 10, corresponding on upper spider 9 and the lower bearing bracket 10 a plurality of welders 11 is housed; Described welder comprises a welding oil cylinder 12, on the piston rod of welding oil cylinder 12 electrode tip holder 13 is housed, and welding electrode 14 is housed on the electrode tip holder 13; Described guider 8 comprises a fixed head 15 shown in Fig. 5, figure, be fixed with accurate line slide rail 16 on the fixed head 15, slide block 17 is equipped with in activity on the accurate line slide rail 16, slide block 17 tops are fixed with guide securement plate 18, one end of guide securement plate 18 is fixed with orienting roll wheel shaft 20 by directive wheel fixed block 19, guide roller 21 is equipped with in activity on the orienting roll wheel shaft 20, the other end of guide securement plate 18 is connected with shift cylinder slurcam 22, and shift cylinder slurcam 22 is connected with the piston rod of shift cylinder 23.Fig. 4 is circuit theory diagrams of the present invention, belongs to prior art so do not describe.
During work, workpiece is placed on the front console 2, drives workpiece by servo-actuating device 7 and on longitudinal movement rail 4, vertically move.When workpiece vertically moves on longitudinal movement rail 4, be fixedly clamped, prevent that workpiece from laterally moving by the guide roller on the guider 8 21.By when workpiece is delivered to assigned address, following welding oil cylinder rises and pressurize, and the welding oil cylinder is depressed one by one on this moment, and each oil cylinder all works alone successively.When first oil cylinder depress welded after, get back to original position, second oil cylinder just begins the work of depressing, and finishes up to row's groove welding.When having welded whole 11 groove backward shift oil cylinders to a side shifting 54mm, servomotor counter-rotating at this moment drives workpiece and moves round about, welds remaining groove, and servomotor shuts down behind the triggering photoelectric sensor.At this moment all following welding oil cylinder retractions, servomotor begins to start, and promotes the workpiece reach, welding second row's groove.
