Patent attributes
The present invention relates to a fault detectable sheet body fixed distance conveying and punching assembly, which may include a rack, a conveying trough seat, a feeding trough, a processing rack and a punching device. On the rack is provided a feed motor and a feed screw. The movable feeding block is sleeved on the feed screw and the movable feeding seat is fixedly connected to the movable feeding seat. On the movable feeding seat is provided a feed lifting cylinder and on the feed lifting cylinder is provided a feed lifting block. On the feed lifting cylinder are equally provided feed blocks which may go through the feeding trough. On the processing rack is also provided a position detecting device which may include a detecting lifting cylinder provided on the processing rack. Under the detecting lifting cylinder is connected the detecting block. On the both sides of the detecting block is provided an acoustic wave range finder. The present invention includes a position detecting device, which may measure the position of the feeding block on the processing station by lifting the acoustic wave range finders on the position detecting device, and conduct integrity check to the fixed distance feeding part and maintain the entire assembly.
