Detailed Description

The utility model provides a door leaf hinge welding positioning tool, which comprises a 1# welding clamping fixture and a 2# welding clamping fixture; the following description is made with reference to the accompanying drawings.

FIG. 1 is a view showing a structure of a # 1 welding jig, in which a is a front view; b is a side view; and c is a top view. The No. 1 welding mould shown in the figure is assembled and welded together by a bottom plate 1, a right baffle plate 2, a side baffle plate 3 and a height base plate 4; one side of the right baffle plate 2 and one side of the side baffle plate 3 are vertical to each other and are vertically welded on the bottom plate 1; the height backing plate 4 is parallel to the right baffle 2, vertical to the side baffle 3, tiled on the bottom plate 1 and welded on the bottom plate 1;

FIG. 2 is a view showing a structure of a # 2 welding jig, in which a is a front view; b is a side view; and c is a top view. The No. 2 welding mould shown in the figure is assembled and welded together by a positioning bottom plate 5, a vertical plate 6, a hinge lug backing plate 7, a baffle plate 8 and a main body backing plate 9; a hinge lug backing plate 7 is arranged between the two vertical plates 6 and is vertically welded on the positioning bottom plate 5 in parallel; baffle 8 is in a riser 6 near vertical welding on positioning bottom plate 5, and two main part backing plates 9 are perpendicular to baffle 8, parallel to each other, the tiling on positioning bottom plate 5 to the welding is on positioning bottom plate 5.

Fig. 3 shows a welding positioning diagram of the door leaf hinge welding tool. As shown in the figure, a hinge lug backing plate 7 is arranged between two vertical plates 6, and the width of the hinge lug backing plate 7 is the same as the thickness of a hinge lug. The bearing hole 10 of the hinge lug is consistent with the direction of the rectangular hole of the door leaf hinge main body (as shown in the top view of the door leaf hinge workpiece in fig. 4).
