Description
Technical field
The invention belongs to spot welding fixture (SWFX) field, specifically, relate to a kind of spot welding fixture (SWFX) that there is refrigerant effect and have preheat function.
Background technology
Spot welding is the method for attachment of a kind of high speed, economy.It is suitable for manufacturing and can adopts overlap joint, joint not to require that airtight, thickness is less than the punching press of 3mm, the thin-plate element of rolling.The indivedual means of spot welds on the contact-making surface of joint weldment.Spot welding requires metal will have good plasticity.Spot-wedling electrode is the strength member that guarantees point quality, and its major function has: (1) is to beam current through work-piece; (2) to workpiece transmission of pressure; (3) lead rapidly the heat of loose weld zone.Spot welding is divided into direct welding and the large class of indirect welding two conventionally.During direct welding, electrode is by two side direction weld feeds of workpiece.Typical direct welding mode is the most frequently used mode, and at this moment all there is electrode impression the both sides of workpiece.The conductive plate of large bonding area is done bottom electrode, can eliminate or alleviate like this impression of lower work piece.Be usually used in the spot welding of decorative panel.Weld the direct welding of two or more spot welding simultaneously, use a transformer and each electrode is in parallel, at this moment, the impedance of all current paths must be substantially equal, and the surface state of each welding position, material thickness, electrode pressure all need identical, guarantee is basically identical by the electric current of each solder joint, so adopt the two-sided multiple spot welding of a plurality of transformers.
Spot welding need to complete by fixture, for example Chinese Patent Application No. 201110442055.4, within open day, be within on 07 08th, 2012, to disclose the patent application document that a name is called a kind of spot welding fixture (SWFX) and spot-welding technology, this invention relates to a kind ofly can avoid rosin joint, dry joint and fried fiery phenomenon, and the spot welding fixture (SWFX) that uses of the spot-welding technology with higher welding efficiency, comprise jig main body and be located at battery core rest area and the fuse rest area on described jig main body, between described battery core rest area and fuse rest area, being provided with and keeping away a hole.With respect to prior art, this inventive point welding clamp can be good at locating the position of fuse and metal tape, and can adjust the height of capillary, improves point quality, reduces failure welding rate, boosts productivity, cost-saving.This patent is exactly a kind of spot welding fixture (SWFX), and the development of these fixtures has brought very large convenience to people's productive life, has also improved production efficiency, and workman operates these fixtures, easily, but also has inconvenient place to need to improve.For example, when carrying out not equal thickness or different materials spot welding, nugget will be asymmetric with its interface, but to one side skew of slab or conduction, poor thermal conductivity, the result of skew will reduce thin or conduction, workpiece penetration rate that thermal conductivity is good, and Joint Strength reduces.Nugget skew is by two workpiece heat production and radiating condition identical causing not.When thickness does not wait, thick resistance is large, interface ionization electrode is far away on one side, therefore heat production is many, heat radiation is few, causes thick of nugget deflection; When material is different, it is difficult that the material heat production of conduction, poor thermal conductivity is easily dispelled the heat, therefore nugget is also partial to this material.And in order to prevent nugget skew, in advance workpiece being carried out to preheating is one of very feasible way.But prior art needs a lot of technology and steps to workpiece preheating, has not only wasted time cost, has also increased cost of labor.Also have a problem to be exactly: workman is when operation, hot especially while working especially during the broiling summer, easily heatstroke, when threatening workman's life security, has also reduced operating efficiency.
Summary of the invention
the problem that 1, will solve
For prior art mid point, weld the situation of existing nugget skew, and adopt existing heater to heat to exist, program is complicated, cost is high, and workman's easily heatstroke in the process of operation, the problem that operating environment is poor, the invention provides a kind of spot welding fixture (SWFX) that has refrigerant effect and have preheat function.
2, technical scheme
In order to reach object of the present invention, the present invention adopts following technical scheme:
Have refrigerant effect and have the spot welding fixture (SWFX) of preheat function, comprise clamp, positioner, base, gripper shoe and positioning table, described clamp is positioned at a side of base upper surface; Described gripper shoe has two, lays respectively at the both sides of base lower surface; Described positioner is positioned at a side of base upper surface; Described positioning table is positioned at the centre of base upper surface, also comprises eddy current heater and fan, and described eddy current heater is fixed on the lower surface middle part of base; Described fan is fixed on base; The power of described eddy current heater is 700 watts.
Preferably, the diameter of described fan is 15-20cm.
3, beneficial effect
Than prior art, beneficial effect of the present invention is:
(1) the present invention includes clamp, positioner, base, gripper shoe and positioning table, clamp is positioned at a side of base upper surface; Gripper shoe has two, lays respectively at the both sides of base lower surface, and positioner is positioned at a side of base upper surface; Positioning table is positioned at the centre of base upper surface, also comprises eddy current heater and fan, and eddy current heater is fixed on the lower surface middle part of base.Fan is fixed on base, and the power of eddy current heater is 700 watts, like this when being needed preheating by the workpiece of spot welding, directly start eddy current heater, workpiece is heated, heating fast, and heat and completely weld, avoid the waste of energy, reduce costs; Meanwhile, workman can open fan in hot summer in the course of work, gives oneself cooling, avoids heatstroke, has protected workman's safety;
