Thus, the automatic feeding is completed,

on the contrary, after receiving the boring machine processing completion signal, the boring machine moves the interactive positioning device 2 to a position (i.e. the other interactive tooling plate up-and-down mechanism 13) opposite to the idle double-row U-shaped conveying beam 131, the screw nut transmission mechanism 132 of the idle double-row U-shaped conveying beam 131 starts to perform an extending motion, meanwhile, the zero-point positioner 211 on the positioning workbench 211 releases the first interactive tooling plate 138, after the first interactive tooling plate is extended in place, the plurality of oil cylinders 135 start to be ejected synchronously, and at this time, the double-row supporting strip 136 is matched with the inner side hole 1382 of the first interactive tooling plate 138 through the double-row cylinder 1361. It should be noted that the internal holes 1382 on the first interactive tooling plate 138 and the internal four holes 232 on the second interactive tooling plate 23 are identical in structure and effect. After positioning, the machined first interactive tooling plate 138 and the workpiece are lifted until the first interactive tooling plate 138 completely leaves the zero positioner 211, and after detecting that the lifted levelness is in place, the screw-nut transmission mechanism 132 is slowly pulled back. Thus, the two rows of the upper and lower mechanisms 13 of the two interactive tooling plates are staggered to repeatedly convey and recycle workpieces, and automatic feeding and discharging are completed.

To sum up, the utility model discloses following beneficial effect has: through the design and application of the automatic feeding device, the workpiece to be processed is conveyed and discharged in a staggered and continuous mode, the processing production efficiency is increased, and the potential safety hazard of manual operation is greatly reduced.
