Abstract
The invention discloses a grounding conduction device for welding, which comprises a conduction rod, wherein one end of the conduction rod is provided with a copper lug, and the other end thereof is provided with a boss; the conduction rod is sleeved with a guide sleeve; one end of the guide sleeve is provided with a stop block; a chamber is formed between the guide sleeve and the conduction rod; a spring is arranged in the chamber; and one end of the spring abuts against the boss of the conduction rod, and the other end thereof abuts against the stop block of the guide sleeve. The grounding conduction device for welding is simple in structure and easy to realize; a pretightening force is applied to the conduction rod by the spring arranged between the conduction rod and the guide sleeve, so that the conduction rod can be tightly attached to a workpiece to perform conduction; and tightening screws are used, so that the rotation of the conduction rod is effectively prevented, and the conduction rod can work more smoothly, thereby preventing the twisting of a cable due to the rotation with the conduction rod and further avoiding the torsion failure of the cable.
Description
Technical field
The present invention relates to a kind of welding earth conduction device.
Background technology
When adopting electric welding machine welding, need workpiece grounding, at present, the earth conduction device of usual employing contact, but, the earth conduction device of existing contact and absorption surface defective tightness, easy generation loosens, and when welding for workpiece rotary annular-seam, easily makes cable be wound around.
Summary of the invention
The object of the invention is to for the problems referred to above, provide a kind of structure simple, be easy to realize, earth conduction device can be used with welding of workpiece close contact.
The object of the invention is to be achieved through the following technical solutions:
A kind of welding earth conduction device, comprise contact rod, one end of described contact rod is provided with the copper lug for stube cable, its other end is provided with boss, and contact rod is arranged with fairlead, and described fairlead one end is provided with block, and form a chamber between fairlead and contact rod, be provided with spring in described chamber, one end of described spring is resisted against on the boss of contact rod, and its other end is resisted against on the block of fairlead.
Further, the outer surface of described fairlead is provided with external screw thread, and it is connected with fixed head by nut, is provided with insulating case between described fixed head and fairlead.
Further, described contact rod has strip gathering sill, on described fairlead, corresponding gathering sill position has screwed hole, and is provided with the holding screw matched with this screwed hole, and described holding screw lower end, through screwed hole, is arranged in gathering sill.
Beneficial effect of the present invention is, described welding earth conduction device structure is simple, be easy to realize, the spring arranged between contact rod and fairlead, to contact rod pretightning force, makes contact rod and workpiece fit tightly conduction, and the setting of holding screw, effectively prevent contact rod from rotating, more steady when contact rod is worked, thus prevent cable transfer and be wound around, cause cable to reverse and damage.
Accompanying drawing explanation
Fig. 1 is the structural representation of welding earth conduction device of the present invention.
In figure:
1, contact rod; 2, nut; 3, spring; 4, fairlead; 5, holding screw; 6, gathering sill; 7, copper lug; 8, fixed head; 9, insulating case.
Embodiment
Technical scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
Please refer to shown in Fig. 1, Fig. 1 is the structural representation of welding earth conduction device of the present invention; In the present embodiment, a kind of welding earth conduction device, comprise contact rod 1, one end of described contact rod 1 is provided with the copper lug for stube cable, and its other end is provided with boss, and contact rod 1 is arranged with fairlead 4, described fairlead 4 one end is provided with block, and forms a chamber between fairlead 4 and contact rod 1, is provided with spring 3 in described chamber, one end of described spring 3 is resisted against on the boss of contact rod 1, and its other end is resisted against on the block of fairlead 4.
When the present invention uses, contact rod 1 one end is by copper lug 7 stube cable, and the other end and absorption surface, and the spring 3 arranged between contact rod 1 and conductive sleeve 4, to contact rod 1 one pretightning forces, make itself and workpiece fit tightly and play electric action.
The outer surface of fairlead 4 is provided with external screw thread, and it is connected with fixed head 8 by nut 2, positioning action installed by fixed head 8, and be provided with insulating case 9 between fixed head 8 and fairlead 4, unclamp nut 2, the i.e. position of adjustable fairlead 4 and fixed head 8, thus the compression degree of control spring 3, to control the size of pretightning force.
Contact rod 1 has the gathering sill 6 of strip, on described fairlead 4, corresponding gathering sill 6 position has screwed hole, and be provided with the holding screw 5 matched with this screwed hole, described holding screw 5 lower end is through screwed hole, be arranged in gathering sill 6, it can effectively prevent contact rod 1 from rotating, more steady when contact rod 1 is worked, thus prevent cable transfer and be wound around, cause cable to reverse and damage.
Above embodiment has just set forth general principle of the present invention and characteristic; the present invention does not limit by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
