(III) advantageous effects

The invention provides a limiting mechanism for drilling a pin shaft. The method has the following beneficial effects:

1. this round pin axle is stop gear for drilling compares with traditional locking device, when the one end to the round pin axle was drilled the operation, its other end can not be because the existence production moment of resistance of moment of resistance, also can not have residual stress to exist after the processing finishes, ensures its mechanical properties.

2. This round pin axle is stop gear for drilling, and this stop gear carries out the round pin axle after spacing, and its drilling operation is accomplished in aqueous, compares with traditional operation mode, and it not only can adsorb most noise, simultaneously, can avoid the smear metal piece to scatter around, all has fine guard action to operating personnel and processing environment.

3. This round pin is stop gear for axle drilling, after processing, start servo motor, servo motor's drive end drive second driving plate and mounting panel are reciprocating, promote the round pin axle after the continuous promotion rivers of reciprocating of sieve erode the processing for its cooling, erode the piece of adhesion simultaneously and break away from rather than, and with the iron fillings absorption of aquatic, play the effect of purified water, the live time of extension water, resources are saved.
