Gap is easily produced between female and motor head, is difficult to avoid during operation.
The content of the invention
The invention aims to the shortcoming for the nut for solving to be not applied for Multiple Type present in prior art,
And a kind of detachable electrode of the projection welder proposed.
To achieve these goals, present invention employs following technical scheme：
Design and be provided with screwed hole, and electrode tip holder at the top of a kind of detachable electrode of projection welder, including electrode tip holder, the electrode tip holder
Screw top is connected with electrode tip, and the middle part of the electrode tip is provided with through hole, and the through hole is movably installed with for positioning projection welding
The alignment pin of nut, the top of the alignment pin is in round table-like, and the top surface of the electrode tip is provided with the peace parallel with through-bore axis
Fill in hole, the mounting hole and be movably installed with mounting blocks, the bottom of the mounting blocks is connected with the 3rd spring, the 3rd spring
The other end and the bottom surface of mounting hole connect, the side of the mounting hole inwall is provided with groove, and the opposite side of the groove is connected
There is the perforation of penetrating electrode head, the sides of the mounting blocks is connected with the pressing plate with matching grooves, the pressure by second spring
The opposite side of plate is connected with the push rod through perforation, and the one end of the push rod away from pressing plate is provided with pressing board.
It is preferred that, gap is left between the screwed hole of the electrode tip and electrode tip holder, and it is interior provided with limiting plate, the limit
Position plate is provided with positioning hole corresponding with alignment pin.
It is preferred that, one end that the alignment pin is located inside electrode tip holder screw top hole is connected with the first spring, and described the
The other end of one spring and the bottom surface of screwed hole are connected.
A kind of detachable electrode of projection welder proposed by the present invention, beneficial effect is：The present apparatus is provided with truncated cone-shaped
The alignment pin of shape, the central through hole for inserting project-welding nut plays a part of positioning, and alignment pin can be with comparative electrode head
Move up and down, can so position the nut of different model, and the gap between nut and electrode tip, be difficult to keep away in operation
Exempt from, can determine that the top surface of project-welding nut and electrode tip is completely attached to by the cooperation of pressing plate and groove, such welding effect
More preferably.
Brief description of the drawings
Fig. 1 is a kind of general structure schematic diagram of the detachable electrode of projection welder proposed by the present invention；
Fig. 2 is enlarged drawing at a kind of detachable electrode Fig. 1 of projection welder proposed by the present invention A.
