Abstract
The invention discloses a spot-welding fixture with an electric heating plate, belonging to the field of spot-welding fixtures. The spot-welding fixture comprises a clamp, a positioning block, a base, two support devices, a positioning seat and the electric heating plate, wherein the clamp is arranged on one side of the upper surface of the base, the two support devices are arranged on two sides of the lower surface of the base respectively, the Z-shaped positioning block is arranged on one side of the upper surface of the base, the positioning seat is arranged at the center of the upper surface of the base, and the electric heating plate is arranged in the middle of the lower surface of the base. When the spot-welding fixture is in use, a worker can directly heat workpieces, and then the heated workpieces can be welded, so that the operation is convenient, and the cost is lowered. The spot-welding fixture has the advantages of simple structure, reasonable design and easiness in manufacture.
Description
Technical field
The invention belongs to the spot welding fixture (SWFX) field, specifically, relate to a kind of spot welding fixture (SWFX) with electric hot plate.
Background technology
Spot welding is the method for attachment of a kind of high speed, economy.It is suitable for manufacturing can adopt 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 that plasticity preferably will be arranged.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 the 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 usually.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 the electrode impression 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 simultaneously the direct welding of two or more spot welding, use a transformer and by each electrode parallel connection, 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 numbers 201110442055.4, open day be to disclose the patent application document that a name is called a kind of spot welding fixture (SWFX) and spot-welding technology on 07 08th, 2012, 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, being provided with and keeping away a hole between described battery core rest area and fuse rest area.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 the 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 the 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 make thin or conduction, workpiece penetration rate that thermal conductivity is good reduce, and Joint Strength reduces.Nugget skew is by two workpiece heat production and radiating condition identical causing not.When thickness did not wait, thick resistance was large, the interface ionization electrode is far away on one side, and heat radiation is few therefore heat production is many, causes thick of nugget deflection; When material was different, it is difficult that the material heat production of conduction, poor thermal conductivity is easily dispelled the heat, therefore nugget also is partial to this material.And in order to prevent the 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 the workpiece preheating, has not only wasted time cost, has also increased cost of labor.
Summary of the invention
The problem that 1, will solve
For the prior art mid point, weld the situation of existing nugget skew, and adopt existing heater to heat the problem that program is complicated, cost is high that exists, the invention provides a kind of spot welding fixture (SWFX) with electric hot plate.
2, technical scheme
In order to reach purpose of the present invention, the present invention adopts following technical scheme:
A kind of spot welding fixture (SWFX) with electric hot plate, comprise clamp, locating piece, base, bracing or strutting arrangement and positioning seat, and described clamp is positioned at a side of base upper surface; Described bracing or strutting arrangement has two, lays respectively at the both sides of base lower surface; Described locating piece is positioned at a side of base upper surface; Described locating piece is " Z " type; Described positioning seat is positioned at the centre of base upper surface; Also comprise electric hot plate, described electric hot plate is positioned at the lower surface middle part of base.
Preferably, the power of described electric hot plate is 100-300 watt.
3, beneficial effect
Than prior art, beneficial effect of the present invention is:
(1) the present invention includes clamp, locating piece, base, bracing or strutting arrangement and positioning seat, clamp is positioned at a side of base upper surface, and bracing or strutting arrangement has two, lays respectively at the both sides of base lower surface; Locating piece is positioned at a side of base upper surface; Positioning seat is positioned at the centre of base upper surface; Also comprise electric hot plate, electric hot plate is positioned at the lower surface middle part of base, like this when the workpiece by spot welding needs preheating, directly start electric hot plate, workpiece is heated, heating fast, and heat and completely namely weld, avoid the waste of energy, reduce costs;
(2) power of electric hot plate of the present invention is 100-300 watt, is applicable to the processing miniature parts, and power is crossed conference mash welder is impacted, so power can not be excessive, the too small effect that does not have heating, and power selection 100-300 watt, 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, clamp; 2, locating piece; 3, base; 4, electric hot plate; 5, bracing or strutting arrangement; 6, positioning seat.
