Abstract
The utility model discloses spot welding bolt includes bolt head and polished rod, is equipped with transition portion between this bolt head and the polished rod to be equipped with heavy platform around transition portion department on this bolt head. The structure enables the transition part of the spot welding bolt to have a larger radius, can enhance the strength of the bolt head and the transition part of the spot welding bolt, and can avoid the problem of insufficient strength between spot welding pieces caused by shunting during spot welding.
Description
[technical field]
The utility model relates to machinery/material processing field, refers in particular to a kind of spot welding bolt of fastening usefulness.
[background technique]
The spot welding bolt that is used for machinery or materials processing comprises polished rod and bolt head two-part, as shown in Figure 1, be provided with intermediate location 30 between polished rod 10 and the bolt head 20, it generally is fillet structure, the fillet size is generally R0.5 or R1, the fillet of its polished rod diameter parts and bolt head intermediate location is too little, and then the head strength deficiency of bolt does not reach the mechanical property of requirement; If fillet is too big, then because the influence of shunting during spot welding, and solder joint 40 is not had and weldment between welding fully merge, thereby cause spot welding strength deficiency between the weldment.The spot welding bolt that existing industry is used all exists above-mentioned contradiction and shortcoming not to solve.
Therefore, strength problem between bolt head intensity that a kind of size that can solve because of the intermediate location fillet between spot welding bolt light rod diameter parts and the bolt head influences and weldment need be provided, bolt head intensity height, fully welding fusion between solder joint and the weldment, the spot welding bolt that spot welding intensity is high.
[summary of the invention]
The purpose of this utility model is to provide a kind of bolt head intensity height, fully welding fusion between solder joint and the weldment, the spot welding bolt that spot welding intensity is high.
For realizing the utility model purpose, provide following technological scheme:
The utility model spot welding bolt comprises bolt head and polished rod, is provided with transition part between this bolt head and the polished rod, and is provided with heavy stand around the transition part place on this bolt head.This structure makes the transition part of spot welding bolt that bigger radius can be arranged, and can strengthen the bolt head of spot welding bolt itself and the intensity of transition part, the shunting in the time of simultaneously can avoiding spot welding again and cause the problem of strength deficiency between the weldment.
The described heavy stand degree of depth is generally 0.5～1.5mm.This transition part can be inclined-plane or fillet.Fillet radius is generally greater than R0.5mm, and for example fillet is R1.5mm.So, adopt big fillet, intermediate location can be selected suitable fillet radius and transition altitude, transition altitude can be according to the degree of depth setting of heavy stand, can suitably exceed on the heavy stand, but should not be too many above the height of heavy stand, generally the ratio of the radius of this transition part fillet and the heavy stand degree of depth is 0.8～1.2.Like this, can guarantee the intensity of bolt head, the influence that can reduce again even shunt when avoiding spot welding, thus guarantee weld strength.
The contrast prior art the utlity model has following advantage:
The utility model is provided with heavy stand around the transition part place on this bolt head, make the transition part of spot welding bolt that bigger radius can be arranged, and can strengthen the bolt head of spot welding bolt itself and the intensity of transition part, has also strengthened intensity between the some weldment simultaneously.
[description of drawings]
Fig. 1 is the schematic perspective view of existing spot welding bolt;
Fig. 2 is the stereogram of the utility model spot welding bolt;
Fig. 3 is the plan view of the utility model spot welding bolt;
Fig. 4 be among Fig. 3 A-A to sectional view.
[embodiment]
See also Fig. 2～4, the utility model spot welding bolt comprises bolt head 2 and polished rod 1, be provided with transition part 3 between this bolt head 2 and the polished rod 1, and the place around transition part 3 is provided with heavy stand 4 on this bolt head 2, heavy stand 4 also should adopt circular design in the present embodiment, the radius of heavy stand 4 is less than the radius of bolt head 2, and solder joint 5 is arranged at the edge of bolt head 2 and the position between the heavy stand 4.It is the fillet of R1.5mm that this transition part 3 adopts size, can certainly be the inclined-plane.These heavy stand 4 degree of depth are 1.5mm, and the quantity of solder joint 5 is 3, more help fixing.
This structure makes the transition part of spot welding bolt that bigger radius can be arranged, specifically can be adjusted according to the degree of depth and the radius of heavy stand 4, for example the degree of depth of heavy stand 4 is remained radius with transition part and is 1: 1 ratio, so can strengthen the bolt head of spot welding bolt itself and the intensity of transition part, simultaneously be provided with heavy stand 4 between transition part 3 and the solder joint 5, the shunting in the time of can effectively avoiding spot welding and cause the problem of strength deficiency between the weldment.
The above only is preferred embodiment of the present utility model, and protection domain of the present utility model is not limited thereto, and anyly all belongs within the utility model protection domain based on the equivalent transformation on the technical solutions of the utility model.
