Abstract
The utility model discloses a spot welding fixture with hooks and a heating plate and belongs to the field of spot welding fixtures. The spot welding fixture with the hooks and the heating plate comprises a clamp, a positioning device, a base, two vertical supporting plates and a positioning table, wherein the clamp is positioned on one side of the upper surface of the base, and 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 spot welding fixture with the hooks and the heating plate further comprises the heating plate and the hooks, and the heating plate is a resistance heating plate and is positioned in the middle part of the lower surface of the base; the hooks are positioned on a side surface of the base. When the spot welding fixture with the hooks and the heating plate is used, workpieces can be directly heated by workers, after heating, welding can be performed immediately, the operation is convenient, the cost is lowered, meanwhile, the workers can hang various tools required in the work onto the hooks and can conveniently take and use the tools, attractive and elegant effects are achieved, and potential safety hazards to production can not be caused.
Description
Technical field
The invention belongs to spot welding fixture (SWFX) field, specifically, relate to a kind of spot welding fixture (SWFX) with hook 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.The operator of general spot welding is in the process of operation, need to use various tool, such as spanner etc., and for easy to operate, generally instrument will be placed on to the place that can get at any time, the result causing is like this that workman arbitrarily puts instrument, not only not attractive in appearance, but also bring potential safety hazard can to other people contact, the management of these Dou Gei factories has brought a difficult problem.
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 the problem that program is complicated, cost is high and exist workman's operation tool to place nowhere, the invention provides a kind of spot welding fixture (SWFX) with hook 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 hook and heating plate, comprise clamp, positioner, base, vertical gripper shoe and positioning table, 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, also comprises heating plate and hook, and described heating plate is resistance heated plate, is positioned at the lower surface middle part of base; Described hook is positioned on the side of base.
Preferably, the power of described heating plate is 500 watts.
Preferably, described hook is 4-10.
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, 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, also comprise heating plate and hook, heating plate is resistance heated plate, be positioned at the lower surface middle part of base, hook is positioned 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, people can hang over the required various tool of using in work on hook simultaneously, take conveniently, and elegant in appearance, can not cause potential safety hazard to producing,
(2) power of heating plate of the present invention is 500 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.
