[specific embodiment]
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, 2, be the first embodiment of the utility model spot welding device 100, it comprises soldering tip 2 and the holding parts 1 that is connected soldering tip.Described soldering tip 2 is provided with the end 20 for welding, and described end 20 is flat pattern, and it comprises two sides, first side 201 and second side on the other side 202 that long axis direction is connected with holding parts.In the present embodiment, establishing the plane vertical with the outrigger shaft of described spot welding device is horizontal plane, and described end 20 comprises that one has the first end face 22 of certain angle with horizontal plane, as Fig. 3, shown in 4, described the first end face and horizontal plane have angle a, and this angle a is acute angle.Preferably, described a is 0 ° to 8 °.Like this, what can increase described end face and welding object can contact area, improves the efficiency of welding.
Described end 20 is provided with the circular-arc depressed part 21 to holding parts direction depression from the first end face 22, and described the first end face 22 is positioned at the periphery of described depressed part 21.The projected outline of described depressed part 21 on horizontal plane is a major arc, and a wherein side of described major arc and end intersects, tangent with another side.In the present embodiment, for intersecting with first side 201, tangent with second side 202.Like this can be by welding object; enamel-covered wire etc. normally; part is accommodated or is pressed in depressed part 21; effectively increase the contact area of welding; and form nugget at welding body surface; wrap the welding objects such as enamel-covered wire, can the structure after welding be played a very good protection, make to weld not frangibility of object.Certainly, these are only preferably a kind of embodiment of the utility model, in selectable other embodiments, also can there are other distortion, such as, described major arc is not necessarily tangent with second side 202, also can be separated by a distance with it, the projection of described depressed part 21 can be also irregular arc, also can be other shapes, so long as there is certain depression, welding object partly can be pressed into, realize the effect that increases solder side, can implement.
As shown in Fig. 5 to 8, be the utility model the second embodiment, itself and first in embodiment roughly the same, difference is, described end 20 ' is also provided with first end face 22 ' intersects, and the second end face 23 ' tilting to holding parts direction.As shown in Figure 7 and Figure 8, described the first end face 22 ' is a ' with horizontal plane angle, and the angle between described the second end face 23 ' and the extended surface of the first end face 22 ' is b.Described angle a ' and angle b are acute angle.Preferably, described a ' is 0 ° to 8 °, and described b is 0 ° to 11 °.Be described the first end face 22 ' and the second end face 23 ' not in same plane, the more close holding parts of described the second end face 23 ' to first end face 22 '.The intersecting lens of the first end face 22 ' and the second end face 23 ' protrudes from the side of described end 20 '.It is upper that described first side 201 ' is positioned at described the first end face 22 ', and second side 202 ' is positioned on described the second end face 23 '.Described depressed part 21 ' is recessed to form to holding parts direction from the first end face and the second end face.Like this, not only can increase the degree of depth of depressed part 21 ', further increase the contact area of welding, can also prevent that second side 202 ' from encountering object to be welded, thereby affect the reliability that welding effect affects product.
Certainly, these are only preferably embodiment of the utility model, in selectable other embodiments, also can have other variations, for example, described depressed part also can be for other shapes, as groove, and bar shaped, so long as can realize increase bonding area, make to weld product and form nugget parcel, can improve product reliability can, can implement.
The foregoing is only better embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; in every case the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or is changed, and all should include in the protection domain of recording in claims.
