Abstract
The utility model belongs to the field of welding processing, and particularly relates to a nut electric welding positioning pin which comprises three parts, namely a first part, a second part and a third part, wherein the first part is a nut guiding part; the second part is a stamping part positioning part; the third part is a fixing part; the fixing part comprises a transitional body and a combined body; the stamping part positioning part is a circular truncated cone; the transitional body and the combined body are cylinders; the nut guiding part is a cylinder with a circular arc chamfer angle at the head part; and the height of the cylinder of the nut guiding part is smaller than the thickness of a to-be-welded nut. The size and the structure of the nut electric welding positioning pin are optimized, and no hole is formed in an end surface of an upper electrode, so that the service life of the upper electrode is prolonged, and the production cost is reduced.
Description
Technical field
The utility model belongs to field of welding processing, relates in particular to a kind of nut electric welding alignment pin.
Background technology
At present; The setscrew nut targeting part of the seat mash welder used nut alignment pin of known band nut conveyer all is designed to a taper, is used for nut conveyor delivery nut to alignment pin the time, and nut is led; In order to prevent that nut from sending less than on the alignment pin time; Top electrode damages the insulated electro bakelite on the alignment pin by pressure, must bore a hole in the lower surface of top electrode, and the hole is of a size of the size of alignment pin targeting part.Since the lower surface centre drill of top electrode a hole, electrode is in long-term use, because nut extruding top electrode subsides in the hole around the lower end face of top electrode, causes top electrode to shorten service life.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned defective, and a kind of nut electric welding alignment pin is provided.
In order to realize the purpose of the utility model, the technical scheme of the utility model is:
A kind of nut electric welding alignment pin divides three parts, and first is the nut guide part; Second portion is the stamping parts location division, and third part is a fixed part, and said fixed part comprises transition body and combination; Said stamping parts location division is a Rotary-table, and said transition body is a cylinder, and said combination is a cylinder; Said nut guide part is a head band circular arc chamfering cylinder, and the cylindrical height of said nut guide part is less than the thickness of the nut of needs welding.
The cylindrical radius of said nut guide part equals the upper base radius through the said Rotary-table after the chamfering, and the cylinder radius of said transition body equals the radius of going to the bottom of said Rotary-table.
The cylinder radius of said combination is less than the cylinder radius of said transition body.
The beneficial effect of the utility model is: through optimizing this alignment pin size and structure, make the top electrode end face without perforate, prolong the service life of top electrode, save production cost.
Description of drawings
Fig. 1 is the structural representation of existing known nut electric welding alignment pin,
Fig. 2 is the utility model structural representation,
Fig. 3 is the utility model assembling sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Embodiment: referring to Fig. 1, Fig. 2, Fig. 3.
A kind of nut electric welding alignment pin divides three parts, and first is the nut guide part; Second portion is the stamping parts location division, and third part is a fixed part, and said fixed part comprises transition body and combination; Said stamping parts location division is a Rotary-table, and said transition body is a cylinder, and said combination is a cylinder; Said nut guide part is a head band circular arc chamfering cylinder, and the cylindrical height of said nut guide part is less than the thickness of the nut of needs welding.
The cylindrical radius of said nut guide part equals the upper base radius through the said Rotary-table after the chamfering, and the cylinder radius of said transition body equals the radius of going to the bottom of said Rotary-table.
The cylinder radius of said combination is less than the cylinder radius of said transition body.
Assembly Instruction Device: the top electrode 5 among Fig. 3 is not hole; Be contained in the bottom electrode 9 behind the combination 4 assembling insulated electro bakelites 7 of nut electric welding alignment pin; Below the combination 4 of nut electric welding alignment pin, spring 8 is housed, bottom electrode nut 6 and bottom electrode 9 are through being threaded.In adopting nut conveyer spot welding nut process; The operative employee at first is placed on stamping parts on the nut electric welding alignment pin, and the floor push that tramps with one's feet again starts the nut conveyer and send nut; After the nut conveyer had sent nut, the signalling of nut conveyer started a seat mash welder and carries out spot welding.Send under the situation not in place at nut; Nut electric welding alignment pin is depressed by top electrode 5; The upper surface of the nut guide part of nut electric welding alignment pin is concordant with the stamping parts upper surface, and the combination 4 lower surfaces compression spring 8 of nut electric welding alignment pin is after top electrode 5 resets; Nut electric welding alignment pin is upspring by spring 8 and is resetted, and insulated electro bakelite 7 can be by pressure break yet.
What the embodiment of the utility model announced is preferred embodiment; But be not limited thereto, those of ordinary skill in the art is very easily according to the foregoing description; Understand the spirit of the utility model; And make different amplifications and variation, but only otherwise break away from the spirit of the utility model, all in the protection domain of the utility model.
