Conveying accuracy related fault detectable integrated sheet body punching and grinding assembly

A conveying accuracy related fault detectable integrated sheet body punching and grinding assembly, comprising:

• a frame;
• a conveying trough seat disposed upon said frame and upon which a sheet to be punched is mounted above a feed trough defined within said conveying trough seat;
• a processing frame disposed upon said conveying trough seat and having a punching device disposed at a punching station for punching a hole within the sheet, and a grinding device disposed at a grinding station for grinding internal peripheral portions of the hole punched within the sheet by said punching device;
• a feed motor operatively connected to a feed screw which is sleeved within a plurality of movable feed blocks;
• said plurality of movable feed blocks are operatively connected to a movable feed seat;
• said movable feed seat is provided with a feed lift cylinder which is operatively connected to a feed lift block;
• a plurality of feed blocks, which are movable through said feed trough, are disposed upon said feed lift block for moving the sheet between said punching station and said grinding station;
• a vertically oriented beam emitter is mounted within said feed lift block for emitting a beam signal;
• and
• a beam receiver is mounted within said grinding device so as to receive said beam signal from said beam emitter and thereby ensure that the sheet is precisely positioned with respect to said punching device such that the hole may be accurately punched within the sheet.
