Said riser middle part offers the mandrel installing hole, is provided with mandrel circumferential registration keyway in the said mandrel installing hole; Offer working face on the medial surface of said riser, said working face is perpendicular to said mandrel installing hole;
Said top board is provided with the guide hole that is used for drilling, and said guide hole axis is downwards and perpendicular to the axis of said mandrel installing hole;
Second step circle and the thread segment adaptive with said mandrel installing hole are justified, are used for to the descending first step that is provided with successively of said mandrel; Said first step circle is provided with keyway one, the second step circle is provided with keyway two, and said keyway one is consistent with respect to the circumferencial direction of said mandrel axis with keyway two; Said first step circle is the mandrel locating surface towards the end face of second step circle, and said mandrel locating surface contacts the working face on the said riser;
Said positioning key one is located between the mandrel circumferential registration keyway and keyway two in the said mandrel installing hole;
Said positioning key two is located in the said keyway one.
Said guide pin bushing has mesopore, and the inwall of said mesopore is provided with guide chute; Said positioning key two protrudes from said keyway one, and the two sides of said positioning key two projections are adaptive with the two sides of said guide chute respectively.
Distance on the said top board between guide hole axis and the said working face equals axis and the said guide pin bushing of key connecting hole of required drilling on the said guide pin bushing towards the distance of the working face of said riser.
Guide pin bushing drilling tool of the present invention comprises two parts, and first constitutes through riser, base plate and top board, and second portion is a mandrel, and mandrel is installed in the installing hole on the riser, utilizes positioning key one with both location, plays the circumferential positioning action to mandrel; The locating surface of mandrel contacts (keyway one, keyway two are that a clamping is processed simultaneously) with the working face of riser, guaranteed the concentricity in installing hole axle center on mandrel axle center and the said riser; First adds man-hour in addition, has guaranteed guide hole axis and the perpendicularity of installing hole axial line on the top board; So just guarantee the high positioning reference that two parts of the present invention form.
As far as workpiece-guide pin bushing, on the first step circle of mandrel, be provided with positioning key two, guide chute just in time feasible and that guide pin bushing is interior is suitable, has played the circumferential positioning action of guide pin bushing; Working face on the end face applying riser of guide pin bushing, the perpendicularity of assurance guide pin bushing axis and riser; Matching relationship in the first step circle of mandrel and the guide pin bushing between the circle has guaranteed axiality between the two; Finally guaranteed guide hole and the perpendicularity between the guide pin bushing axial line on the top board, and the guide hole axle center is through guide chute horizontal center line on the guide pin bushing.And then can adapt to scale processing, and can guarantee perpendicularity and the position degree between the guide chute between aperture and the guide pin bushing axis.The present invention has guaranteed the perpendicularity of aperture and guide pin bushing axis, has improved production efficiency.
