Description
Technical field:
The utility model relates to field of welding devices, relates in particular a kind of self-priming spot-wedling electrode.
Background technology:
Spot-wedling electrode is the strength member that guarantees point quality, and its major function has: the first, to beam current through work-piece; The second, to the workpiece transmission of pressure; The 3rd, lead rapidly the heat of loose weld zone.In production in enormous quantities, spot welding obtains extensive use.When High-Speed Automatic pay-off was delivered to the electrode hole fast with the contact, under effect of inertia, the placement location of contact just can not coincide with the electrode hole, the position skew can occur, place uneven, the phenomenons such as electrode is pushed out, spot welding solder skip.And the generic point welding electrode of prior art does not effectively address this problem at present.Chinese patent Granted publication CN 201399659 Y for example, at on 02 10th, 2010 Granted publication day, the name of innovation and creation is called spot-wedling electrode, this application case discloses a kind of spot-wedling electrode of small-sized rod-like element, combined innovation by two semi-circular recesses and elastic rubber ring, avoided scuffing and the electric spark on small-sized rod-like element surface that the erosion of small-sized rod-like element is hindered, efficiently solve battery copper pin bottom or the undesirable problem of other small-sized rod-like element welding effects, but this application case does not solve the solder skip problem of battery copper pin bottom.For another example Chinese patent Granted publication CN 201807830 U, at on 04 27th, 2011 Granted publication day, the name of innovation and creation is called embedding type spot welding electrode, this application case discloses a kind of spot-wedling electrode, the combined innovation of the inlaid hole by sleeping bar and the installing handle of electrode tip, realization is convenient for changing or dismantles the purpose of electrode tip, efficiently solve the problem of waste of material when changing electrode tip, but this application case there is not effectively to solve the problem that position skew, workpiece placement out-of-flatness and solder skip etc. appear in spot-wedling electrode.The utility model provides a kind of simple in structure by the matrix of spot-wedling electrode and the combined innovation of strong magnetic, matrix rapid heat dissipation in pinpoint welding procedure, and the spot welding position is smooth, does not have the self-priming spot-wedling electrode of solder skip phenomenon.
The utility model content:
The generic point welding electrode does not have effectively to solve the problem that the position skew occurs in pinpoint welding procedure, place the phenomenons such as injustice, spot welding solder skip in the utility model solution prior art, a kind of self-priming spot-wedling electrode is provided, by the matrix of spot-wedling electrode and the combined innovation of strong magnetic, address the above problem.
In order to solve the technical problem of above-mentioned existence, the utility model is taked following technical proposals: a kind of self-priming spot-wedling electrode, comprise matrix, electrode hole, feed well, strong magnetic, top electrode and bottom electrode, it is characterized in that, described electrode hole and feed well are arranged on the upper surface of matrix, described electrode hole is communicated with feed well, the edge conducting of described feed well and matrix, described strong magnetic be arranged on electrode hole under, the degree of depth in described electrode hole is greater than the degree of depth of feed well, described top electrode be arranged on electrode hole directly over, bottom electrode links to each other with matrix.
When mounted, as long as strong magnetic is packed in the manufactured goods of matrix, and strong magnetic is fixed in the matrix gets final product.In use, first matrix is fixed, and bottom electrode is connected with matrix, top electrode be arranged on the electrode hole directly over, then by High-Speed Automatic pay-off the contact is sent to feed well fast, the contact is fallen in the electrode hole along feed well afterwards, simultaneously workpiece is needed the position of spot welding to be placed on the electrode hole, by the acting in conjunction of top electrode, matrix and bottom electrode, workpiece and contact point are welded into one, take out at last this workpiece, and prepare the spot welding of next workpiece.Matrix links to each other with bottom electrode, forms the closed-loop path with top electrode, forms large electric current so that workpiece spot welding is in when welding, and finishes spot welding work; Electrode hole is the last dwell point in contact, and the electrode hole increased the area of dissipation around the spot welding, improves the matrix rate of heat dispation, prevents the expand with heat and contract with cold out-of-flatness phenomenon of rear appearance of matrix; Feed well makes things convenient for the contact to transmit; Strong magnetic in the process that transmit at a high speed the contact, is offset the inertia of contact, and the center guiding function in magnetic field, makes the contact fall into difficult ejection the behind the electrode hole, prevents the position skew of contact; Upper/lower electrode is for the spot welding of contact and workpiece provides power supply; The degree of depth in electrode hole is greater than the degree of depth of feed well, so that after the contact leaves feed well, have gravity, with the magnetic field force acting in conjunction of strong magnetic, guarantees to be difficult for ejecting after the electrode hole is fallen in the contact.
Preferably, on the bottom surface of matrix, described strong magnetic is provided with shutoff.Prevent that strong magnetic displacement is moving, put forward the stability in high-strength magnetic magnetic field.
Preferably, described matrix is provided with fixing hole.Before this self-priming spot-wedling electrode uses, by fixing hole matrix is fixed, prevent the movement of position when matrix is worked, improve the stability of this self-priming spot-wedling electrode.
Preferably, the end face of described matrix is provided with the chute consistent with the workpiece shape.Reduce the deviation of workpiece pinpoint welding procedure position, improve the precision of spot welding.
Preferably, at the two ends of chute, described matrix is provided with dodges groove.Dodge groove, make things convenient for preventing of workpiece, reduce simultaneously the volume of some welding work table, be conducive to the heat radiation of a postwelding, prevent the distortion after matrix expands with heat and contract with cold.
Owing to take above-mentioned technical scheme, a kind of self-priming spot-wedling electrode that the utility model provides has such beneficial effect: simple in structure, stable performance, by the matrix of spot-wedling electrode and the combined innovation of strong magnetic, solve the problem of phenomenons such as contact position skew, the not gentle spot welding solder skip of workpiece placement in pinpoint welding procedure, occur.
