High -speed EMUs door section bar adds clamping apparatus relates to EMUs door section bar processing technology field, and it includes base, two short supporting shoes of straightway, oval segmentalarc supporting shoe, a plurality of A type pressing tongs, two type B pressing tongss and locating piece. Workpiece coordinate and the state that the lathe coordinate system does not coincide appearedin work piece alignment in -process very easily when current door section bar processing clamping had been solved to these anchor clamps, leaded to the work piece radian of work piece processing intercepting wrong, caused the waste product, and the clamping inefficiency leads to the low technical problem who increases with manufacturing cost of lathe availability factor. The beneficial effects ofthe utility model are that: use this to add the clamping apparatus, the alignment once and need not once more the alignment during work piece clamping and can process in the time of only need be on installing the lathe with an
