For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product. In addition, for simplicity and clarity of understanding, only one of the components having the same structure or function is schematically illustrated or labeled in some of the drawings.

FIG. 1 is a schematic diagram of an exemplary embodiment of a weld positioning assembly. FIG. 2 is a schematic view of an assembly structure of the welding positioning assembly at another angle. Fig. 3 is an exploded view of the weld positioning assembly. Referring to fig. 1-3, the weld positioning assembly is used to position a switching device 80 (see fig. 6) in cooperation with a welding electrode 70. The welding positioning assembly includes a base 10, a sliding block 20, a positioning member 30, an elastic member 40 and a driving member 50.

Referring to fig. 1, the base 10 has a working plane S which, in use, is disposed parallel to the ground and facing upwards for placing the switching device 80. The positioning member 30 is disposed on the working plane S. Fig. 2 is an assembled structural view of the welding positioning assembly of fig. 1 after being rotated 180 degrees around a first direction X parallel to the working plane S, and fig. 3 is an exploded structural view of the welding positioning assembly of fig. 2. Referring to fig. 2 and 3, a slider 20 is movably provided to the base 10 in a first direction X and a reverse direction thereof, the slider 20 being used to detachably fix the welding electrode 70. The slider 20 can move the welding electrode 70 fixed thereon toward the positioning member 30 along the first direction X, so that the welding electrode 70 and the positioning member 30 clamp the switch device 80 (see fig. 6). The elastic member 40 applies force to the base 10 and the slider 20 to provide elastic force for driving the slider 20 toward the positioning member 30. The driving member 50 is disposed on the base 10, and the driving member 50 can apply a force to the sliding block 20, so that the sliding block 20 moves back to the positioning member 30 against the elastic force of the elastic member 40.

In an exemplary embodiment, referring to fig. 1-3, the base 10 includes a base plate 12, a support bracket 14, a guide 16, and an anti-roll bar 18. The substrate 12 has a working plane S. The support 14 is arranged on the side of the substrate 12 facing away from the working plane S. The guide 16 is disposed on the bracket 14, the guide 16 has a cylindrical guide portion 17 with an axis parallel to the first direction X, the slider 20 is slidably fitted over the guide portion 17, and the welding electrode 70 fixed to the slider 20 is inserted through the substrate 12 and extends from the working plane S. The anti-roll bar 18 is inserted through the slide 20 and the support 14 in a direction perpendicular to the first direction X, and in the illustrated embodiment, the anti-roll bar 18 is inserted into a slide slot extending in the first direction X on the support 14, and the anti-roll bar 18 is capable of moving with the slide 20 in the first direction X and in the opposite direction, and of blocking the slide 20 from rotating about the axis of the guide 17. The structure is simple and convenient to process, and the slider 20 is arranged on one side of the substrate 12, which is opposite to the working plane S, so that more operating space can be reserved on the working plane S. However, the present invention is not limited to this, and in other exemplary embodiments, the slider 20 may be slidably disposed on the base 10 by other means. The anti roll bar 18 can be replaced by other structures, such as abutment on both sides of the slide 20. The guide portion 17 may also have another shape extending in the first direction X, and it is also possible to omit the anti-roll bar 18 without the slider 20 rotating about the guide portion 17.

Fig. 4 is a schematic cross-sectional structural view of the welding positioning assembly, and referring to fig. 2, 3 and 4, in an exemplary embodiment, the elastic member 40 is a compression spring sleeved on the guide portion 17 and abutting against the guide 16 and the slider 20, respectively. The guide 16 is slidably disposed through the bracket 14 along the first direction X. The welding positioning assembly further comprises two position adjusting members 15, which are two screws in the illustrated embodiment, the screws are inserted through the guide member 16 along the first direction X and are threadedly connected to the bracket 14, and the guide member 16 abuts against the head of the screw serving as the position adjusting member 15 under the elastic force of the elastic member 40. The structure is simple and the cost is low. Since the guiding element 16 always abuts against the head of the screw, the position of the guiding element 16 along the first direction X can be adjusted by adjusting the depth of the screw entering the bracket 14, so as to change the degree of compression of the elastic element 40 and the magnitude of the elastic restoring force, thereby changing the abutting force of the welding electrode 70 against the component 82 to be welded when clamping the switch device 80. The weld locating assembly is capable of adapting to the welding requirements of different switchgear 80 by varying the abutment force on the switchgear 80. However, the present invention is not limited to this, and the position adjusting members 15 may be replaced by other structures in other exemplary embodiments, and the number of the position adjusting members 15 may be adjusted according to actual requirements, and only one position adjusting member 15 may be provided.

In an exemplary embodiment, referring to fig. 2-3, the drive member 50 includes a cylinder 52 and an insulating top block 54. The air cylinder 52 is provided to the base 10 along the first direction X. An insulating top block 54 is arranged at the output end of the air cylinder 52, and the air cylinder 52 can push the sliding block 20 to move through the insulating top block 54. Thereby preventing the cylinder 52 from contacting the welding electrode 70 during the pushing of the slider 20 and improving safety during the driving.
