Tailored blank laser welding jig for six spliced parts

The invention discloses a tailored blank laser welding jig for six spliced parts, comprising a mounting platform. A pre-positioning mechanism, a positioning baffle mechanism, a positioning pushing mechanism, a profiling positioning part and an electromagnet adsorption mechanism are arranged on the mounting platform; one six spliced part is composed of an A-column upper beam plate, a B-column top plate, a B-column vertical plate, a B-column bottom plate, a doorsill plate and an A-column vertical plate; the pre-positioning mechanism is used for pre-positioning the A-column upper beam plate; the positioning pushing mechanism is matched with the outer side edge of the six spliced part; the inner side edge of the six spliced part is matched with the profiling positioning part; and the electromagnet adsorption mechanism is used for adsorbing and fixing the six spliced part. According to the scheme, through mutual cooperation of the pre-positioning mechanism, the positioning baffle mechanism, the positioning pushing
