Describe according to the electrode cap connecing for narrow side weld 4 of the utility model embodiment below with reference to Fig. 1 to Fig. 4, this electrode cap 4 is assemblied on welding equipment, the surface of electrode cap 4 connecting welding parts 10 when welding.
According to the electrode cap connecing for narrow side weld 4 of the utility model embodiment, as depicted in figs. 1 and 2, comprising: Part I 40 and Part II 50.Wherein, Part I 40 is cylindrical, and the lower surface of Part I 40 has installing hole 41 with connecting welding equipment, Part II 50 connecting welding parts 10.
Part II 50 upwards extends from the upper surface of Part I 40, a part for the upper surface of Part II 50 is formed as the circular flat 51 that diameter d is 6mm, the central axis setting of Part I 40 is departed from the center of circle of circular flat 51, and the remainder of the upper surface of Part II 50 is formed as the curved surface 52 that tilts to extend from top to bottom.That is to say, electrode cap 4 is offest electrode cap 4, and in direction from top to bottom, Part II 50 cross-sectional areas reduce gradually.When welding, circular flat 51 connecting welding parts 10, because the diameter d of circular flat 51 is 6mm, electrode cap 4 is less with the contact-making surface of weldment 10.
Particularly, electrode cap 4 connecting welding parts 10 energising when welding, the weldment 10 energisings fusing after heat that has a resistance forms solder joint.Because electrode cap 4 is less with the contact area of weldment 10, while therefore welding, electric current concentrates on circular flat 51, and the nugget of formation is less and reliable, and welding quality is higher.
According to the electrode cap connecing for narrow side weld 4 of the utility model embodiment, the end face of electrode cap 4 is the circular flat 51 that diameter d equals 6mm, thereby reduces the contact area of electrode cap 4 and weldment 10, improves welding quality.
In embodiment more of the present utility model, as shown in Figure 3, the center of circle of circular flat 51 and the distance L of cylindrical central axis are 5mm.
Particularly, as shown in Figure 3, the higher limit (Rz of the surface roughness Rz of circular flat 51
max) equal 25 μ m.Thus, the surface of circular flat 51 is comparatively level and smooth.
More specifically, as shown in Figure 3, curved surface 52 is inclined-plane 52a, and angle theta between inclined-plane 52a and circular flat 51 is 35 degree.Wherein, inclined-plane 52a is oval face, thereby is convenient to the processing of electrode cap 4.
Further, the height of Part I 40 and Part II 50 and H are 20mm.That is to say, the height H of electrode cap 4 is 20mm.
In a concrete example of the present utility model, as shown in Figure 3, the height H of electrode cap 4 is 20mm, and electrode cap 4 comprises Part I 40 and Part II 50.Wherein, Part I 40 is cylinder, the part of the upper surface of Part II 50 is that diameter d is the circular flat 51 of 6mm, the center of circle of circular flat 51 and the distance L of cylindrical central axis are 5mm, the remainder of the upper surface of Part II 50 is for being inclined-plane 52a, and the angle theta between inclined-plane 52a and circular flat 51 is 35 degree.
With reference to figure 4, in the correlation technique connecing in narrow side weld, weldment 10 is provided with salient point 3, to coordinate the electrode cap 4 according to the utility model embodiment.
Particularly, as shown in Figure 4, weldment 10 comprises: the first welded plate 1 and the second welded plate 2.The second welded plate 2 is located at a side of the first welded plate 1, and the surface of vicinity first welded plate 1 of the second welded plate 2 is provided with multiple spaced salient points 3, and each salient point 3 is formed as the hemispherical projections of extending towards the first welded plate 1 from the second welded plate 2.The part that each salient point 3 is the second welded plate 2 forms along the direction towards the first welded plate 1 is recessed.The salient point upper surface 32 of each salient point 3 is formed as recessed arcwall face downwards, and its salient point lower surface 31 is formed as the arcwall face protruding downwards.
According to the shape of the electrode cap 4 of the utility model embodiment can with the shape adaptation of salient point 3, when welding, the circular flat 51 of electrode cap 4 is only butted in salient point upper surface 32, thereby avoid electrode cap 4 to cross the shunting that closely causes welding current to the edge of salient point 3, and then raising welding quality, the outward appearance of beautifying weldment 10.
In the description of this description, the description of reference term " embodiment ", " some embodiment ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And specific features, structure, material or the feature of description can be with suitable mode combination in any one or more embodiment or example.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: in the situation that not departing from principle of the present utility model and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claim and equivalent thereof.
