Abstract
The utility model discloses a gantry type spot welding nut tool, which comprises a gantry red copper body and a lower support red copper body, wherein the gantry red copper body is located above the lower support red copper body, a square through groove is arranged in the middle of the gantry red copper body, vertical through holes are arranged in both sides of the lower support red copper body, cylindrical ceramic core rods are arranged on the upper ports of the through holes, bolts are arranged on the lower ports of the through holes, springs are arranged in the through holes, and the lower part of the lower support red copper body is connected to a red copper insertion rod. According to the utility model, the central distance of a welding nut conforms to requirements and the welding efficiency is improved, and the gantry type spot welding nut tool belongs to the technical field of machinery.
Description
Technical field
The utility model belongs to field of mechanical technique, especially relates to a kind of planer-type spot welding nut frock.
Background technology
Lap joint and flanging joint are adopted in spot welding usually.Joint comprises the workpiece group of two or more equal thickness or non-equal thickness.At present adopting the spot welding of coremaking rod is the special shape of indirect welding, and this form is particularly suitable for the spot-welded structures narrow space, and electrode is difficult to or maccessiable workpiece at all.Existing spot-welding equipment all is designed to single spot welding, single-point joint namely, for example need to weld two nuts on the workpiece of required welding, and the centre-to-centre spacing to two nuts has requirement, and present welder equipment need to weld twice workpiece, be difficult to guarantee in the centre-to-centre spacing ± 0.5mm of two nuts, and welding efficiency is also low.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of and can guarantee that welded nut centre-to-centre spacing meets the requirements and can improve the planer-type spot welding nut frock of welding efficiency.
Technical solution adopted in the utility model is: a kind of planer-type spot welding nut frock, comprise planer-type red copper body, lower support red copper body, planer-type red copper body is positioned at above lower support red copper body, planer-type red copper body middle part is provided with a square three-way groove, lower support red copper body both sides are equipped with a vertical through holes, and the through hole upper port is provided with cylinder pottery plug, and the through hole lower port is provided with bolt, be provided with spring in through hole, lower support red copper body bottom is connected with the red copper insertion rod.
the beneficial effects of the utility model are: the utility model planer-type spot welding nut frock, be provided with two cylinder pottery plugs on lower support red copper body, use the disposable spot welding of completing two nuts of this frock energy, production efficiency can improve 80%, simple to operate, for difform workpiece, only need to change shape and the size of planer-type red copper body (interior also have be called gantry fixed mount), simultaneously according to the spot welding principle, need not electric welding machine is reequiped, not only with low cost, and technique is simple, easy to operate, in the fine assurance two nut bore centre-to-centre spacing ± 0.5mm of some postwelding energy, can't affect product appearance, torsional strenght, pressure-off power.This frock just converts on the basis of general point welding fixture, and equipment cost is low.
Description of drawings
Fig. 1 is the utility model cutaway view.
In figure, 1, planer-type red copper body, 1.1, groove, 2, lower support red copper body, 2.1, through hole, 2.2, cylinder pottery plug, 2.3, spring, 2.4, bolt, 3, the red copper insertion rod.
The specific embodiment
Be below the utility model preferred embodiment, but therefore do not limit protection domain of the present utility model.
With reference to shown in Figure 1, a kind of planer-type spot welding nut of the utility model frock, comprise planer-type red copper body 1, lower support red copper body 2, planer-type red copper body 1 is positioned at lower support red copper body 2 tops, planer-type red copper body 1 middle part is provided with a square three-way groove 1.1, lower support red copper body 2 both sides are equipped with a vertical through holes 2.1, through hole 2.1 upper port are provided with cylinder pottery plug 2.2, through hole 2.1 lower port are provided with bolt 2.4, be provided with spring 2.3 in through hole 2.1, lower support red copper body 2 bottoms are connected with red copper insertion rod 3.Described cylinder pottery plug 2.2, spring 2.3 and bolt 2.4 coordinate, and can play good buffering effect when place work piece and nut.
Operation principle of the present utility model is: in the middle of actual the use, planer-type red copper body 1 upper end is connected with the upper horn of mash welder, red copper insertion rod 3 is connected with the lower horn of mash welder, the workpiece lower end is placed on lower support red copper body 2, it is fixing with planer-type red copper body 1 that groove 1.1 is passed in the workpiece upper end, then nut is inserted on cylinder pottery plug 2.2, presses the mash welder switch, carry out spot welding.
the utility model planer-type spot welding nut frock, be provided with two cylinder pottery plugs 2.2 on lower support red copper body 2, use the disposable spot welding of completing two nuts of this frock energy, production efficiency can improve 80%, simple to operate, for difform workpiece, only need to change shape and the size of planer-type red copper body (interior also have be called gantry fixed mount), simultaneously according to the spot welding principle, need not electric welding machine is reequiped, not only with low cost, and technique is simple, easy to operate, in the fine assurance two nut bore centre-to-centre spacing ± 0.5mm of some postwelding energy, can't affect product appearance, torsional strenght, pressure-off power.This frock just converts on the basis of general point welding fixture, and equipment cost is low.
