Description
Technical field
It is related to special shape nut the utility model relates to nut field of locating technology, especially one kind to match with bottom outlet precision
Close the special projection welding nut electrode positioning device used.
Background technique
Nut projection welding belongs to using relatively broad Joining Technology form in automobile industry, and automatic/semi-automatic nut is convex
Soldering equipment quickly and efficiently, but in efficient behind but needs to stablize and reliably welding quality and positioning accuracy are as quality
Guarantee.The screw thread specification and bottom outlet aperture engaged therewith difference of general project-welding nut are smaller, therefore ordinary electrode positioning form is
It can satisfy location requirement, but in the case where differing greatly in face of screw thread specification and bottom outlet aperture engaged therewith, it is necessary to
Extraordinary electrode design is met technique requirement.
Utility model content
The purpose of this utility model is that it is fixed to provide a kind of special projection welding nut electrode in place of making up the deficiencies in the prior art
Position device.Positioning during the positioning early period of nut projection welding and projection welding push can be guaranteed, and need to overcome spiral shell
Line specification and bottom outlet aperture engaged therewith differ biggish premise calls, guarantee that electrode design can meet big bottom outlet simultaneously
The positioning accuracy request of precision positioning and small dimension nut thread size.
The purpose of this utility model is realized by following technological means:
A kind of special projection welding nut electrode positioning device, it is characterised in that: including small axle diameter positioning column, large-diameter positioning column
With seam allowance location structure, small axle diameter positioning column is co-axially located at the upper surface of large-diameter positioning column, under large-diameter positioning column
Floor design goes out seam allowance location structure, which includes the upper seam allowance end and lower seam allowance end of coaxially connected setting, should
Upper seam allowance end and the bottom surface of large-diameter positioning column are coaxially connected, and diameter at seam allowance end is greater than the diameter at lower seam allowance end on this, and
The maximum gauge at upper seam allowance end is greater than the diameter of large-diameter positioning column.
Moreover, the small axle diameter positioning column and large-diameter positioning column are designed using round-corner transition.
The advantages and positive effects of the utility model are as follows:
1, the present apparatus use Based on Dual-Aperture location structure, realize diplopore precision positioning, meet screw thread specification and and its
The bottom outlet aperture of cooperation differ greatly in the case where processing request.
2, the present apparatus is designed using round-corner transition, has not only met the gentle of transition, but also meet the skill of intensity and fatigue strength
Art requirement.
3, the present apparatus is that a kind of design is reasonable, structure is practical, special projection welding nut electrode positioning device easy to use, this
Device can satisfy the requirement that special shape nut and bottom outlet class fit use.

Specific embodiment
Embodiment of the utility model will be described in detail below with reference to the attached drawings, it should be noted that the present embodiment is narrative
, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of special projection welding nut electrode positioning device (positioning pin), including small axle diameter positioning column 1, large-diameter positioning column 2
With seam allowance location structure, small axle diameter positioning column is co-axially located at the upper surface of large-diameter positioning column, small axle diameter positioning column and big axis
Diameter positioning column is designed using round-corner transition.
Seam allowance location structure is designed in the bottom surface of large-diameter positioning column, which includes coaxially connected set
The upper seam allowance end 3 and lower seam allowance end 4 set, seam allowance end and the bottom surface of large-diameter positioning column are coaxially connected on this, seam allowance end on this
Diameter be greater than lower seam allowance end diameter, and the maximum gauge at upper seam allowance end be greater than large-diameter positioning column diameter.
The design principle of the utility model are as follows:
Due to needing diplopore precision to position, therefore need to design Based on Dual-Aperture location structure, and need to consider large-diameter bottom
Hole positioning pin and large aperture bottom outlet height dimension reserved when cooperating, because height dimension will meet the positioning of projection welding initial stage simultaneously thus
It is required that and during pushing under positioning pin in contracting moving process, the length of the reserved movement of the various pieces of Based on Dual-Aperture positioning pin is filled
Foot.
And need to pay attention to nut thread bottom and detent fit structure, it is ensured that the flatness and stabilization that nut is placed
Property, while needing to meet in the design, Based on Dual-Aperture positions the round-corner transition design of the transition intensity of the different diameters of axle between shank, both
Meet the technical requirements for gently meeting intensity and fatigue strength again of transition.
