Abstract
The utility model discloses a welding head for welding a grounding claw, wherein the welding head is integrally formed by connecting a smaller rectangle under a larger rectangle; four holes are formed on the upper part of the larger rectangle in parallel; a transverse long hole is formed under the four holes; a groove which leads to the top of the welding head is arranged on the upper end of the long hole; the groove penetrates through the second hole and the third hole of the four holes; a point for connecting a welding temperature-sensing line is arranged under the transverse long hole; and a bulge is arranged on the lower surface of the lower smaller rectangle. Two ends of the lower surface of the lower smaller rectangle are respectively provided with one bulge. The middle bulge corresponds to a welding point in the middle of the grounding claw, and the welding contact area is narrowed to the only middle point simultaneously, so that the welding speed and welding efficiency are favorable to improve. The bulges at two ends are used for preventing from influencing the welding operation owing to the fact that the two ends are tilted due to being stressed in the process of welding the grounding claw.
Description
Technical field
The utility model relates to the welding machine technical field, particularly relates to a kind of welding head that welds the ground connection pawl.
Background technology
The existing multiplex manual welding of ground connection pawl.Manual welding ground connection pawl was had relatively high expectations to employee's proficiency, age.The manual welding quality is also unstable, and fraction defective is higher.Through trial-production, adopt pawl welding yield in bonding machine welding ground to reach 100%.Existing welding head bottom is a flat surface, and whole surface all is heating surface (area) (HS.Long heating surface (area) (HS is influential to speed of welding and efficient.And the ground connection pawl only has a solder joint.
The utility model content
Technical problem to be solved in the utility model is to be unfavorable for welding the technical problem of ground pawl and a kind of Kazakhstan bar welding head that can be used for preferably welding ground pawl of designing for above-mentioned existing welding head.This welding head lower surface respectively has a projection at middle and two ends.Middle projection is corresponding with a solder joint in the middle of the ground connection pawl, also is simultaneously the welding contact area to be narrowed down to only have middle this point, is conducive to improve speed of welding and welding efficiency.When the projection at two ends was used for preventing the welding of ground connection pawl, the middle stressed two ends perk that causes, butt welding were practiced midwifery and are given birth to impact.
The technical problem that the utility model requires to solve can be achieved through the following technical solutions:
A kind of welding head that welds the ground connection pawl, described welding head integral body is that larger rectangle below connects a less rectangle, four holes are also shown in large rectangle top, below, described four holes has the elongated hole of a horizontal stroke, the elongated hole upper end has groove to lead to the welding head top, described groove passes through between second, third hole from four holes, and the elongated hole below of described horizontal stroke has any to be used for the connecting welding temp.-sensing wire, and the less rectangular undersurface in described below has a projection.
Respectively there is a projection at less rectangular undersurface two ends, described below.
Owing to adopted as above technical scheme, the utlity model has following features:
Be conducive to improve speed and the efficient of welding ground connection pawl.The welding yield reaches 100%.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the utility model comprises the larger rectangle 1 that is positioned at the top and the rectangle 2 that is positioned at the below that links with rectangle 1, four circular holes 3 are also shown in rectangle 1 top, there is the elongated hole 4 of a horizontal stroke four circular hole 3 belows, elongated hole 4 upper ends have a groove 5 to lead to rectangle 1 top, and elongated hole 4 belows have 1: 6 to be used for the welding temp.-sensing wire.
There is a projection 7 at rectangle 2 lower surface centers, and two ends respectively have a projection 8. projections 7 corresponding with the solder joint of ground connection pawl, and the welding contact area narrows down to a point, is conducive to improve speed of welding and efficient.When projection 8 is used for preventing the welding of ground connection pawl, middle stressed two ends perk, thus affect the welding of ground connection pawl.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. welding head that welds the ground connection pawl, described welding head integral body is that larger rectangle below connects a less rectangle, four holes are also shown in large rectangle top, below, described four holes has the elongated hole of a horizontal stroke, the elongated hole upper end has groove to lead to the welding head top, and described groove passes through between second, third hole from four holes, and the elongated hole below of described horizontal stroke has a bit for the connecting welding temp.-sensing wire, it is characterized in that the less rectangular undersurface in described below has a projection.
2. the welding head of welding ground connection pawl as claimed in claim 1 is characterized in that respectively there is a projection at less rectangular undersurface two ends, described below.
