Description
Technical field
The utility model is related to arrive a kind of automatic welding device.
Background technology
Projection welder is the commonly used equipment in auto parts and components production, is mainly used for the welding to stamping parts.The type of projection welding
Very much, in addition to plate projection welding, also nut, screw class part projection welding, wire rod intersect projection welding, pipe projection welding and plank etc..
Automobile overspeed governor support rod is connected by fixing bracket with car body, which is U-shaped body, bottom position weldering
Connected nut.Since workpiece is smaller, workpiece shift is often resulted in when projection welder welds it, keeps welding effect undesirable, rejection rate
It is higher.It is existing using clamping by the way of, welded again after workpiece and nut are gripped using clamp body in advance, no
But process is increased, it is time-consuming and laborious, and also effect is also undesirable.
Invention content
The utility model provides a kind of nut projection welding machine top electrode assembly, realize to small-sized speed limit support rod fixed frame and
The welding of nut avoids the workpiece shift formed when welding, reduces rejection rate, it can be achieved that while quickly positioning.
In order to achieve the above object, the technical solution adopted in the utility model is：
A kind of nut projection welding machine top electrode assembly, it is characterized in that：Including upper electrode holder, upper electrode holder is equipped with top electrode,
Top electrode is fixed on by hexagon-headed bolt I in upper electrode holder, and the top electrode centre is equipped with U-lag, U-lag both sides
Equipped with preceding catch and rear catch, preceding catch and rear catch are fixed on by connecting bolt in top electrode, the U-shaped of the top electrode
Groove center position is equipped with longitudinal positioning pin, which is fixed on by hexagon-headed bolt II in top electrode, further includes heat-resisting
Magnet, the heat-resisting magnet are arranged in top electrode U-lag bottom position.
The utility model has the beneficial effects that by equipped with front and rear baffle and heat-resisting magnet, realize the positioning of workpiece,
Workpiece is avoided in welding shift, effect simple in structure is ideal.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left side schematic view of the utility model Fig. 1.
In figure：1 top electrode；2 hexagon-headed bolts I；3 positioning pins；4 hexagon-headed bolts II；5 heat-resisting magnet；6 upper electrode holders；7
Quick connector；Catch before 8；Catch after 9；10 connection bolts.
Specific implementation mode
The utility model is described further below by embodiment.
Referring to Fig. 1~2, the utility model includes upper electrode holder 6, and upper electrode holder 6 is equipped with top electrode 1, and top electrode 1 passes through
Hexagon-headed bolt I 2 is fixed in upper electrode holder 6, and 1 centre of top electrode is equipped with U-lag, the U-lag groove body size
And height and the fixing bracket shape of welding match.U-lag both sides are equipped with preceding catch 8 and rear catch 9, preceding catch 8 and rear gear
Piece 9 is fixed on by connecting bolt 10 in top electrode 1, after so that the U-lag of top electrode 1 is put into workpiece after connection, before being not in
Backward shift.The U-lag centre of the top electrode 1 is equipped with longitudinal positioning pin 3, which passes through hexagon-headed bolt
II 4 are fixed in top electrode 1, which not only plays the role of electrodes conduct in welding, and the spiral shell of welding may be implemented
Mother's positioning, ensure that the accuracy of welding.Further include heat-resisting magnet 5, which is arranged in the U-lag bottom of top electrode 1
Position, the heat-resisting magnet 5 can realize the absorption to workpiece, further ensure the positioning of workpiece.The utility model upper electrode holder 6
Upper both ends are additionally provided with quick connector 7, and the perforation connection of quick connector 7 for accessing cooling water, is realized when necessary to upper electrode holder
It is cooling.
It should be noted that embodiment described in the utility model is only to realize the preferred embodiment of the utility model,
To belonging to the utility model general idea, and it is only obvious change, all should belong to the protection range of the utility model
Within.
