[0038] Please refer to Figure 3 and Figure 4The utility model provides a kind of welding tool for electric drive axle leak detection mechanism, for positioning in the welding process of above-mentioned electric drive axle leak detection mechanism, including base 5 and limiting strut 6. Among them, base 5 has oppositely arranged first limiting slot 51 and second limiting slot 52, first limiting slot 51 is used to place the first connecting part 2 of electric drive axle leak detection mechanism, second limiting slot 52 is used to place the second connecting part 3 of electric drive axle leak detection mechanism, to preliminarily position the position of first connecting part 2 and second connecting part 3.The connecting body 1 of electric drive axle leak detection mechanism is made to pass through the via of first connecting part 2 and second connecting part 3, so that first connecting part 2 and second connecting part 3 are set on connecting body 1, then limiting strut 6 is installed between first connecting part 2 and second connecting part 3 by screw etc. fastener, and limiting strut 6 is oppositely arranged with base 5, so that the position of first connecting part 2 and second connecting part 3 is completely fixed on connecting body 1. Subsequently, first connecting part 2 and second connecting part 3 are welded on connecting body 1, to shorten the welding time of electric drive axle leak detection mechanism, to improve the production efficiency of electric drive axle leak detection mechanism in turn.

[0039] Exemplarily, the placement platform 21 of first connecting part 2 and second connecting part 3 is located in first limiting slot 51 and second limiting slot 52 respectively, so that first connecting part 2 is stably placed in first limiting slot 51, and second connecting part 3 is stably placed in second limiting slot 52.

[0040] In an example, the number of limiting strut 6 is more than one, specifically can be provided with 1, 2, 3 etc., according to actual demand to set.

[0041] In some embodiments, the base 5 includes a first limiting member 53 and a second limiting member 54 connected together, and the first limiting member 53 and the second limiting member 54 have a gap therebetween, which forms the first limiting slot 51 or the second limiting slot 52.

[0042] Exemplarily, the first limiting member 53 and the second limiting member 54 have two groups and are oppositely arranged, so that the base 5 has the first limiting slot 51 and the second limiting slot 52 oppositely arranged.

[0043] Please see Figure 5 In an application example, the first limiting member 53 and the second limiting member 54 can be provided as L-shaped angle iron, the second limiting member 54 is connected to the first limiting member 53 by welding, and the first limiting member 53 and the second limiting member 54 are welded in staggered positions, so that the first limiting member 53 and the second limiting member 54 have a gap therebetween to form the first limiting slot 51 or the second limiting slot 52.

[0044] Please see Figure 4 And 6In some embodiments, in order to position the hanger ring 11 when welding the hanger ring 11 of the electric drive axle leak detection mechanism, a connecting rod 7 is hinged on the base 5, and a positioning plate 71 is fixedly connected to the end of the connecting rod 7 away from the base 5 by welding or the like. Before welding the hanger ring 11, the connecting rod 7 is rotated so that the bottom of the positioning plate 71 abuts against the outer side wall of the electric drive axle leak detection mechanism connecting body 1, one side of the hanger ring 11 in the width direction abuts against the side wall of the positioning plate 71, and one end of the hanger ring 11 in the length direction is placed flush with the selected end of the side wall of the positioning plate 71 on which the hanger ring 11 abuts, thereby achieving positioning of the hanger ring 11.

The second adjusting part 82 includes, but is not limited to, a bolt, which is connected with the nut, by adjusting the relative position between the bolt and the nut, the bolt is extended or retracted from the end of the L-shaped angle iron, so that the adjusting support rod 8 is elongated or shortened.

[0050] In an application example, the adjusting support rod 8 is provided with at least one, and the number of the adjusting support rod 8 can be set to 1, 2, 3, 4, etc., and the specific number is set according to actual needs. When the adjusting support rod 8 is provided with multiple, multiple parts of the first connecting part 2 and the second connecting part 3 can be simultaneously supported, which is beneficial to improve the efficiency of the electric drive axle leak detection mechanism taken off from the welding tool.

[0051] In some embodiments, in order to reduce the labor input and avoid the falling of the adjusting support rod 8, a plurality of support frames 56 for supporting the adjusting support rod 8 are arranged on the base 5, and the support frame 56 is located between the first limiting groove 51 and the second limiting groove 52. The support frame 56 can be arranged on both sides of the welding tool width direction of the present application.

[0052] Please refer to Figure 8 In some embodiments, the base 5 further includes two oppositely arranged cross beams 57, the first limiting member 53 and the second limiting member 54 are connected to the cross beams 57 and are arranged between the two cross beams 57, and the base 5 is formed by the cross beams 57, the first limiting member 53 and the second limiting member 54.

[0053] In an application example, in order to reduce the cost, the cross beam 57 can be arranged as an L-shaped angle iron, and the cross beam 57, the first limiting member 53 and the second limiting member 54 are connected by welding or the like. The connecting bracket 55 and the support frame 56 can also adopt an L-shaped angle iron, and the connecting bracket 55 and the support frame 56 are connected to the cross beam 57 by welding or the like.

[0054] It should be noted that the positioning of the reinforcing rib 4 of the electric drive axle leak detection mechanism can be realized by marking lines on the first connecting part 2 and the second connecting part 3.
