Mounting hole, be movably installed with mounting blocks in the mounting hole, the bottoms of the mounting blocks is connected with the 3rd spring, the described 3rd
The other end of spring and the bottom surface of mounting hole connect, and the side of the inner wall of the hole installing is provided with groove, the opposite side of the groove
It is communicated with the perforation of penetrating electrode head, the sides of the mounting blocks is connected with the pressing plate with matching grooves, institute by second spring
The opposite side for stating pressing plate is connected with push rod through perforation, and the one end of the push rod away from pressing plate is provided with pressing board.
Preferably, gap is left between the screwed hole of the electrode tip and electrode tip holder, and interior is provided with limiting plate, the limit
Position plate is provided with positioning hole corresponding with alignment pin.
Preferably, one end that the alignment pin is located inside electrode tip holder screw top hole is connected with the first spring, and described
The other end of one spring and the bottom surface of screwed hole connect.
The utility model proposes a kind of projection welder detachable electrode, beneficial effect is：The present apparatus is provided with circle
The alignment pin of platform shape, for inserting the central through hole of project-welding nut, play a part of positioning, and alignment pin can be relatively electric
Cartridge moves up and down, and can so position the nut of different model, and the gap between nut and electrode tip, in operation not
Easily avoid, can determine that the top surface of project-welding nut and electrode tip completely attaches to by the cooperation of pressing plate and groove, so weld
Effect is more preferable.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of projection welder detachable electrode general structure schematic diagram；
Fig. 2 be the utility model proposes a kind of projection welder detachable electrode Fig. 1 A at enlarged drawing.
In figure：Electrode tip holder 1, electrode tip 2, limiting plate 3, alignment pin 4, project-welding nut 5, through hole 6, the first spring 7, pressing board 8,
Perforation 9, groove 10, pressing plate 11, mounting blocks 12, mounting hole 13, second spring 14, the 3rd spring 15, push rod 16.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-2, a kind of detachable electrode of projection welder, including electrode tip holder 1, the top of electrode tip holder 1 are provided with screwed hole, and
And the screw top of electrode tip holder 1 is connected with electrode tip 2, the middle part of electrode tip 2 is provided with through hole 6, and through hole 6 is threaded with for positioning
The alignment pin 4 of project-welding nut 5, the top of alignment pin 4 is in round table-like, and the top surface of electrode tip 2 is provided with and the diameter parallel of through hole 6
Mounting hole 13, mounting blocks 12 is movably installed with mounting hole 13, the bottom of mounting blocks 12 is connected with the 3rd spring 15, the 3rd spring
15 other end is connected with the bottom surface of mounting hole 13, and the side of the inwall of mounting hole 13 is provided with groove 10, and the opposite side of groove 10 connects
The perforation 9 of penetrating electrode first 2 is connected with, the side of mounting blocks 12 is connected with the pressing plate matched with groove 10 by second spring 14
11, the opposite side of pressing plate 11 is connected with the push rod 16 through perforation 9, and the one end of push rod 16 away from pressing plate 11 is provided with pressing board 8.
