(1) technical field

The utility model relates to a kind of new steel plate resistance welder, belongs to field of welding devices.

(2) background technology

The electric resistance welding electric welding machine that is used for the steel plate class at present can be divided into two big classes basically:

1, stationary resistance welder: operator's offhand welds.With the upper/lower electrode of need welding position aligning welding machine, pass through electric current behind the upper/lower electrode workpiece pressing, thereby weld.

2, hand-held resistance welder: the hand-held soldering turret of operator welds.

Above-mentioned existing defective of two quasi-resistance welding machines and deficiency are that automaticity is low, and the welding location is bad, and staff's labour intensity is big, inefficiency, and welding quality is difficult to guarantee.

(3) summary of the invention

For overcoming the defective of prior art, the utility model provides a kind of simple new steel plate resistance welder reasonable in design, easy to operate.

A kind of new steel plate resistance welder, form by workbench, frame, welding electrode I and II, head, operating grip and electrical appliance part, welding electrode I is connected the head bottom, operating grip is connected on the head, it is characterized in that interconnecting by more piece mechanism between frame and head, this mechanism comprises preceding lever arm, back lever arm, cylinder, parallel rod, spring and slide block, wherein:

Back lever arm one end is connected with frame by turning cylinder, and the other end is connected with preceding lever arm by turning cylinder;

The preceding lever arm other end is hinged by hinge and parallel rod, and the parallel rod other end and head are hinged;

Spring is connected before the hinged place of parallel rod down and on the upper hinge of back;

Have the strip chute hole on the slide block, slide block is fixed on the head upper end;

On the lever arm, the piston rod front end on the cylinder had sliding axle before the cylinder rear end was hinged on, and the sliding axle two ends are through in the chute hole on the slide block, can slide along chute hole.

Above-mentioned slide block also can be fixed on the parallel rod upper end.

Electrical appliance part is a prior art, does not give unnecessary details.

The utility model can be placed on workpiece on the workbench when using, and holds operating grip welding electrode I is placed on the part to be welded, connects power supply and can finish welding.The utility model is owing to be connected by more piece mechanism between frame and head, make the welding electrode I scope of activities of resistance welder strengthen, handle control electrode I nimbly and freely, and is free to rotate, promptly reduce operator's labour intensity, improved operating efficiency and welding quality again.

The utility model reasonable in design is easy to operate simple.

(4) description of drawings.

Fig. 1 is the utility model schematic diagram, and Fig. 2 is the utility model schematic top plan view.

Wherein: 1, workbench, 2 frames, 3, welding electrode I, 4, welding electrode II, 5, head, 6, operating grip, 7, back lever arm, 8, preceding lever arm, 9, cylinder, 10, parallel rod, 11, spring, 12, slide block, 13, turning cylinder, 14, hinge, 15, chute hole, 16, piston rod, 17, sliding axle.

(5) specific embodiment

Embodiment:

The utility model embodiment is shown in above-mentioned diagram, form by workbench 1, frame 2, welding electrode I3 and II4, head 5, operating grip 6 and electrical appliance part, welding electrode I3 is connected head 5 bottoms, operating grip 6 is connected on the head 5, it is characterized in that 5 of frame 2 and heads are interconnected by more piece mechanism, this mechanism comprises preceding lever arm 8, back lever arm 7, cylinder 9, parallel rod 10, spring 11 and slide block 12, wherein:

Back lever arm 7 one ends are connected with frame 2 by turning cylinder 13, and the other end is connected with preceding lever arm 8 by turning cylinder 13;

Preceding lever arm 8 other ends are hinged by hinge 14 and parallel rod 10, and parallel rod 10 other ends and head 5 are hinged;

Spring 11 is connected before the hinged place of parallel rod 10 down and on the upper hinge 14 of back;

Have strip chute hole 15 on the slide block 12, slide block 12 is fixed on head 5 upper ends;

On the lever arm 8, piston rod 16 front ends on the cylinder 9 had sliding axle 17 before cylinder 9 rear ends were hinged on, and sliding axle 17 two ends are through in the chute hole 15 on the slide block 12, can slide along chute hole 15.

Need be placed on the workbench 1 by welder's part during welding, after holding handle 6 welding electrode I3 being placed the part to be welded, connect power supply, electrical appliance part will be by setup program, at first control cylinder 9 pressurizations, cylinder 9 work promotion slide blocks 12 move downward head 5 to workpiece and pressurize, cylinder 9 pressurization time-delay 0.2 second (time can according to the welding requirements adjustment) welding machine electric power is connected, electric current forms welding (weld interval can according to the welding requirements adjustment) by welding electrode I3 and workpiece, (time can according to the welding requirements adjustment) cylinder 9 decompressions that welding stopped back time-delay 0.2 second, an impulse stroke finishes.Before the workpiece welding, can reasonably adjust welding parameter according to the difference of welding work pieces, improve welding efficiency and quality.
