Moreover, the welding can only be performed from one side of the metal plates to be welded. The welding efficiency is low, and the welding is unreliable. CONTENT OF THE UTILITY MODEL

[0003] To solve the above-mentioned problems of the existing jig, that is, the jig only has a positioning plate, a plurality of metal plates are placed in the groove of the positioning plate without being clamped, and the welding can only be performed from one side of the metal plates to be welded, the present application provides a laser welding jig.

[0004] The laser welding jig provided by the present application adopts the following technical scheme:

[0005] The laser welding jig comprises a bottom plate and a pressing plate, the bottom plate and the pressing plate are hinged through a hinge, one side of the bottom plate is welded with a supporting block, one side of the pressing plate is welded with a limiting block, a rectangular hole is formed in the middle of the top end of the limiting block, a plug is welded in the middle of the top end of the supporting block, a plug hole is formed in one side of the plug, and a plug pin is movably penetrated into the plug hole.

[0006] Preferably, the hinge comprises one connecting cylinder one, two connecting cylinders two, one bolt and one nut, the connecting cylinder one is welded on the other side of the bottom plate, the two connecting cylinders two are both welded on the other side of the pressing plate, the two connecting cylinders two correspond to the connecting cylinder one, the bolt is movably penetrated into the two connecting cylinders two and the connecting cylinder one, and the nut is threadedly sleeved on the other end of the bolt.

[0007] Preferably, the bottom plate and the pressing plate are both made of a steel plate.

[0008] In summary, the present application has the following beneficial technical effects: by folding the pressing plate and the bottom plate, the plurality of metal plates are positioned, at this time the limiting block is sleeved outside the plug-in block, the plug-in block is provided with a plug hole on one side, and the plug hole is movably penetrated by a plug pin, and the bottom end of the plug pin is attached to the top end face of the limiting block, the pressing plate and the bottom plate are fixed, and then the welding gun outside is penetrated through the plurality of holes on the pressing plate, so that the welding points of the plurality of metal plates can be precisely welded, then the pressing plate and the bottom plate are turned over by 180 degrees, and then the welding gun outside is penetrated through the plurality of holes on the bottom plate to weld the welding points of the plurality of metal plates. Compared with the prior art, not only the metal plate can be clamped, but also the welding points of the metal plate can be welded from multiple surfaces. BRIEF DESCRIPTION OF DRAWINGS
