Detailed description of the invention
As depicted in figs. 1 and 2, a kind of Cylinder Parts outer round surface drilling-hole positioning device, comprises V-block 9, is characterized in: also comprise trip bolt 1, angle steel clamp 2, adjustment screw rod 3, locking nut 4, centering pin 6, location mandril 7;
Described angle steel clamp 2 is fixed on the V-block end face 5 vertical with V-type groove 8 of V-block 9 by trip bolt 1, two limits respectively with upper surface and the end contact of V-block 9, mounting and adjusting screw rod 3 on the limit being positioned at the angle steel clamp 2 on V-block end face 5, this adjustment screw rod 3 is parallel with V-type groove 8 and be positioned at V-type groove 8, by rotating adjustment screw rod 3 adjustable axle to location dimension, adjustment screw rod 3 is provided with locking nut 4; Offer the through hole 10 with its axes normal in the middle part of described location mandril 7, the axis of this through hole 10 and the intersect vertical axis of location mandril 7, and the distance of the location end face of the axis of this through hole 10 and location mandril 7 is definite value S; Described centering pin 6 is cylindrical, its diameter mates with the through hole 10 on location mandril, during use, location mandril 7 is positioned at V-type groove 8, location end face is near the top of adjustment screw rod 3, and as shown in Figure 3, centering pin 6 is connected with the drill chuck 11 on drilling machine vertical principal axis, described centering pin 6 is inserted in the through hole 10 on location mandril 7, now, the distance that drill press spindle axis locates end face with adjustment screw rod is S, is that benchmark can locate the cylinder class workpiece needing surface drilling with S.
Using method:
The utility model one Cylinder Parts outer round surface drilling-hole positioning device, during use, as shown in Figure 1,
1, clamping centering pin 6 on drill chuck of drilling machine;
2, location mandril is placed in V-block groove 8;
3, centering pin 6 is passed the through hole 10 on location mandril 7, pressure is put in V-block groove 8, and radial direction is able to centering, compresses V-block 9 in Drilling machines bench, and adjustment screw rod 3 is held out against the location end face of location mandril 7, determines the initial position adjusting screw rod 3;
4, part axial location dimension is determined:
According to detail drawing requirement, the center, hole that will be ensured by cylinder class workpiece is compared with distance X and the S between Cylinder Parts datum level, if be greater than S, then unscrews locking nut 4, outwards mobile adjustment screw rod 3, and displacement is (X-S); If X is less than S, then unscrew locking nut 4, move inward adjustment screw rod 3, displacement is (S-X).
