The welding and positioning assembly comprises a base 10, a sliding block 20, a positioning piece 30, an elastic piece 40 and a driving piece 50.

Referring to fig. 1, the base 10 has a working plane S which is arranged in use parallel to the ground surface and faces upwards for the placement of the switching device 80. The positioning member 30 is disposed on the working plane S. Fig. 2 is a schematic view of an assembled structure of the welding fixture of fig. 1 after being rotated 180 degrees around a first direction X parallel to the working plane S, and fig. 3 is a schematic view of an exploded structure of the welding fixture 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 drive the welding electrode 70 fixed thereon to move toward the positioning member 30 along the first direction X, so that the welding electrode 70 and the positioning member 30 clamp the switching device 80 (refer to fig. 6). The elastic member 40 applies force to the base 10 and the slider 20 to provide an elastic force that drives 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 slider 20 to move the slider 20 away from the positioning member 30 against the elastic force of the elastic member 40.

In the illustrated embodiment, referring to fig. 1-3, the base 10 includes a base plate 12, a bracket 14, a guide 16, and an anti-roll bar 18. The substrate 12 has a working plane S. The support 14 is disposed on a side of the substrate 12 facing away from the working plane S. The guide member 16 is disposed on the support 14, the guide member 16 has a cylindrical guide portion 17 with an axis parallel to the first direction X, the slider 20 is slidably sleeved on the guide portion 17, and the welding electrode 70 fixed to the slider 20 is disposed through the substrate 12 and extends out of the working plane S. The anti-tilt bar 18 is disposed through the slider 20 and the bracket 14 in a direction perpendicular to the first direction X, and in the illustrated embodiment, the anti-tilt bar 18 is inserted into a chute formed in the bracket 14 and extending in the first direction X, and the anti-tilt bar 18 is movable with the slider 20 in the first direction X and the opposite direction thereof, and is capable of preventing the slider 20 from rotating about the axis of the guide 17. The structure is simple and convenient to process, and the slide block 20 is arranged on one side of the substrate 12, which is away from the working plane S, so that more operation space can be reserved on the working plane S. However, the present invention is not limited thereto, and in other exemplary embodiments, the slider 20 may be slidably disposed on the base 10 by other means. The anti roll bar 18 may be replaced by other structures, such as abutment on both sides of the slider 20. The guide 17 may have other shapes extending in the first direction X, and the anti-roll bar 18 may be omitted without the slider 20 rotating around the guide 17.

The structure is simple and the cost is low. Since the guide 16 always abuts against the head of the screw, the position of the guide 16 in the first direction X can be adjusted by adjusting the depth of the screw into the bracket 14, thereby changing the compression degree of the elastic member 40 and the magnitude of the elastic restoring force, thereby changing the abutting force of the welding electrode 70 against the member 82 to be welded when the switching device 80 is clamped. The weld fixture can accommodate the welding requirements of different switching devices 80 by varying the abutment force against the switching devices 80. However, the present invention is not limited thereto, and the position adjusting members 15 may be replaced by other structures in other exemplary embodiments, and the number of position adjusting members 15 may be adjusted according to actual needs, and only one position adjusting member 15 is possible.
