Description
Technical field
The utility model relates to the spot welding of nut, specifically a kind of nut versatility spot-wedling electrode.
Background technique
The spot welding of nut has been the prior art, such as: application No. is a kind of spot welding nuts disclosed in 2011204116121
Lower electrode, whether that identification nut specification correct, plays the role of mistake proofing, and indeformable after nut electric welding, still
The technical solution of the patent disclosure does not have versatility, that is, uses only for the nut of same model.Application number simultaneously
It ensure that positioning pin to the good location of nut, is welding for a kind of 2011204166991 insulating positioning nut spot-welding electrode
It will not be glanced off when connecing, guarantee welding precision, but the patented technology is also the nut-welding for single model, is not had
Versatility.
Application No. is a kind of 2017201743335 structures for preventing nut spot welding defect, which is also for single
The nut-welding of one model, does not have versatility.
Summary of the invention
The utility model is in order to being that the spot-welding technology of nut has a versatility, that is, a kind of electrode adapts to a variety of types
The spot welding of number nut, spy propose a kind of nut versatility spot-wedling electrode.
The technical solution of the utility model is a kind of nut versatility spot-wedling electrode thus, including lower electrode mounting base, institute
The lower electrode mounting base stated is equipped with lower electrode assemblies, is cavity in the lower electric machine casing in lower electrode assemblies, and pass through upper end
The screw thread of lid screws on to form mount type chamber；The bottom of mount type chamber is equipped with felt pad, and felt pad is equipped with spring, spring top
Positioning pin is withstood again, positioning pin extends upper end cover, and positioning pin corresponds to top electrode and forms spot-wedling electrode, wherein positioning pin and upper
It is isolated between end cap by insulation sleeve, it is characterised in that: the top of the positioning pin is taper one, and the angle of taper one is 60
The bottom of degree setting, positioning pin is equipped with and the guide post of spring cooperation；Positioning pin is additionally provided with limited step in insulation sleeve lower part.
Further improvement is that the spring is in frustum structure, the bottom of spring is embedded on felt pad, spring
The cooperation of the guide post of top and positioning pin.
Further improvement is that lower electrode mounting base and lower electric machine casing bottom are the mating connection of taper two.
The utility model has the advantages that
When in use since the top of positioning pin is taper one in the utility model, the angle of taper one is 60 degree of settings,
It can be applicable in the setting of a variety of nuts, not having to replacement positioning pin at this time can be realized versatility, and the elasticity setting of positioning pin
It facilitates the movement of positioning pin and is limited by insulation sleeve isolation and limited step, positioning pin will not be formed short with lower electrode at this time
The phenomenon that road, also solves the problems, such as the sideslip of positioning pin.
Spring is in frustum structure and is embedded in felt pad, it is made to have the guiding problem an of safety, and the fortune formed
Dynamic relationship is controllable.
Lower electrode mounting base and lower electric machine casing bottom are the mating connection of taper two, fast and easy installation and removal.
The utility model has versatility, and fast and easy mounts and dismounts.
Detailed description of the invention
Fig. 1 is the structural schematic diagram in the utility model in lower electrode assemblies.
Fig. 2 is that the utility model uses assembling structure schematic diagram.
