Stage clip between alignment pin tail end and projection welding electrode seat, it is characterised in that：Cylinder knot of the alignment pin for stainless steel
Structure, the alignment pin outer wrap have the insulating bushing for keeping apart alignment pin with projection welding electrode cap and projection welding electrode seat, in institute
State the stage clip position tactile with the projection welding electrode seated connection and be provided with step-like insulation spacer, will be described by the insulation spacer
Stage clip is kept apart with the projection welding electrode seat.
Further, in order that alignment pin can be coordinated with the nut of plurality of specifications, with reduce change alignment pin when
Between, the head of the alignment pin is ledge structure.So, the nut and parts of small dimension can be placed in the head of alignment pin,
The nut and parts of big specification can be placed in the bottom of ledge structure.
Further, in order to ensure the connection between alignment pin and stage clip, the afterbody of the alignment pin is also ledge structure,
The stage clip is fixed on the ledge structure.
The beneficial effects of the utility model are：This utility model simple structure, by the alignment pin using stainless steel
And in alignment pin outer wrap insulating bushing so that alignment pin is hardly damaged, and the insulating bushing set up can be by alignment pin and electricity
Polar cap and electrode tip holder are kept apart, and welding current can be prevented to shunt, it is to avoid the generation of distributary phenomenon in welding process, it is possible to increase weldering
Intensity and welding quality is connect, while playing a part of guiding, can prevent alignment pin from inclining, be conducive to improving the welding matter of nut
Amount；In the insulation spacer set by the stage clip position tactile with projection welding electrode seated connection in this utility model, can stage clip and projection welding electricity
Electrode seat is kept apart, and preferably solves the shunting problems in welding process, the electric current in welding process is used on welded nut,
Ensure that weld strength；Additionally, this utility model by by the head design of alignment pin be ledge structure, can make alignment pin with
The nut adaptation of plurality of specifications, so as to avoid frequently changing alignment pin, has saved the plenty of time, has been greatly improved welding efficiency.
