Abstract
The invention belongs to the screw head slotting technical field, in particular to a processing method and a device of a screw micro-gap I-shaped trough without burrs. A clamping disc and a milling blade are rotated under the driving of a power source; workpieces are uniformly distributed in the workpiece troughs on the circumference of the clamping disc along the clamping disc and cut by a first milling blade and a second milling blade sequentially under the driving of the clamping disc. The first milling blade withdraws the workpiece after an arc gap is milled; the outlet is arranged on the top of the workpiece but does not perforate the other port of the workpiece. The second milling blade cuts the I-shaped trough in the rotation direction which is reverse to that of the first milling blade. The milling tracks of the two milling blades on the I-shaped trough are crossed at the internal side of the notch, thus forming the micro-gap and generating no burrs at the two ports of the I-shaped trough. The finished workpiece continues to rotate and falls down when the workpiece trough faces downwards under the rotary driving of the clamping disc, thus achieving the milling trough process. The finished screw product of the invention generates no burrs at the two ends of the I-shaped trough, and has extremely high production efficiency.
