Abstract
The utility model discloses a spot welding fixture with a fan and a heating plate and belongs to the field of spot welding fixtures. The spot welding fixture with the fan and the heating plate comprises a clamp, a positioning device, a base, two vertical supporting plates and a positioning table, and further comprises the heating plate and the fan, wherein the clamp is positioned on one side of the upper surface of the base; the two vertical supporting plates are respectively positioned on the two sides of the lower surface of the base; the positioning device is positioned on one side of the upper surface of the base; the positioning table is positioned in the center part of the upper surface of the base; the heating plate is a resistance heating plate, and is positioned in the middle part of the lower surface of the base; the fan is fixed on the side surface of the base. When spot welded workpieces are required to be preheated, the heating plate is directly started for heating the workpieces, the heating is fast, welding is performed immediately after the heating is finished, energy waste is avoided, and the cost is lowered, in addition, during the work in a hot summer, workers can turn on the fan for cooling so as to avoid sunstroke, and the workers are protected to be safe.
Description
Technical field
The invention belongs to spot welding fixture (SWFX) field, specifically, relate to a kind of spot welding fixture (SWFX) with fan and heating plate.
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, 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.Workman is when operation, hot especially while working especially during the broiling summer, and 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 heat to have program complexity, cost is high and have the problem of workman's processing ease heatstroke, the invention provides a kind of spot welding fixture (SWFX) with fan and heating plate.
2, technical scheme
In order to reach object of the present invention, the present invention adopts following technical scheme:
With a spot welding fixture (SWFX) for fan and heating plate, comprise clamp, positioner, base, vertical gripper shoe and positioning table, also comprise heating plate and fan, described clamp is positioned at a side of base upper surface; Described vertical 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; Described heating plate is resistance heated plate, is positioned at the lower surface middle part of base; Described fan is fixed on the side of base.
Preferably, the power of described heating plate is 600 watts.
Preferably, the diameter that described fan is is 15-20cm.
3, beneficial effect
Than prior art, beneficial effect of the present invention is:
(1) the present invention includes clamp, positioner, base, vertical gripper shoe and positioning table, also comprise heating plate and fan, clamp is positioned at a side of base upper surface, vertically gripper shoe has two, lay respectively at the both sides of base lower surface, positioner is positioned at a side of base upper surface, positioning table is positioned at the centre of base upper surface, heating plate is resistance heated plate, be positioned at the lower surface middle part of base, fan is fixed on the side of base, like this when being needed preheating by the workpiece of spot welding, directly start heating plate, workpiece is heated, heating fast, and heat and completely weld, avoid the waste of energy, reduce costs, simultaneously, workman can open fan in hot summer in the course of work, give oneself cooling, avoid heatstroke, protected workman's safety,
(2) power of heating plate of the present invention is 600 watts, is applicable to processing common parts, can complete the heating to workpiece, again impaired loci welding machine not;
(3) the present invention is simple in structure, easy to use, reasonable in design, cost is low.
