The specific embodiment
In Fig. 1 ~ 3,7,8, a kind of boring device that adopts common boring machine machining large taper hole, comprise tapering row 1, on tapering row 1 conical outer wall, be installed with guide groove 2, slide block 4 is installed in guide groove 2 slidably, the screw rod 3 also supporting by supporting base 6 along guide groove 2, is also provided with thrust bearing on the supporting base 6 of one end of close feed arrangement 5.Screw rod 3 passes slide block 4, and forms threaded engagement with slide block 4;
On slide block 4, be fixed with cutter head;
In the termination of screw rod, be provided with the feed arrangement 5 of drive screw 3 rotations.One end of tapering row 1 is supported by bearing block 8, and the other end is connected with main shaft 7, drives whole tapering row 1 to rotate, feed arrangement 5 drive screw 3 rotations simultaneously, thus band movable slider 4 is along screw rod feeding, by the cutter head processing taper hole inwall on slide block 4.
Preferably, described tapering row's 1 tapering is consistent with the tapering in hole to be processed.
In Fig. 1 ~ 5, in described feed arrangement 5, driver plate 52 is rotatable and by spacing being arranged on screw rod 3 of circumference, and driver plate 52 can, around an angle of screw rod 3 rotations, also be provided with the spring 53 for resetting between driver plate 52 and tapering arrange 1; Spring in this example adopts rubber strip.
One side of driver plate 52 is provided with ratchet 55, and ratchet 55 is fixedly connected with screw rod 3; Driver plate 52 is provided with the ratchet 54 coordinating with ratchet 55; On ratchet 54, be also provided with the rubber strip that makes it reset.
Also be provided with for touching the collision block 9 of driver plate 52.Structure, encloses when the every rotation one of main shaft 7 thus, and driver plate 52 bumps against once with collision block 9, and 52 of driver plates rotate an angle, thereby ratchet 54 also drives an angle of ratchet 55 rotations, and screw rod 3 rotates thereupon, is with movable slider 4 to advance.
Preferred as in Fig. 5, in driver plate 52 and the termination of collision block 9 touchings, be also provided with roller 51.Structure, reduces the friction between driver plate 52 and collision block 9 thus.

Preferred as in Fig. 2, described driver plate 52 has an angle with the center line that tapering is arranged 1 cross section, and incline direction is contrary with direction of rotation.Structure thus, the harmful component when reducing driver plate 52 and being impacted, avoids affecting machining accuracy.
In Fig. 7, described guide groove 2 is inverted trapezoidal groove, and correspondingly slide block 4 cross sections are also trapezoidal.Structure, guarantees machining accuracy thus.
For the designing and calculating of the amount of feeding, first to select threaded screw rod, determine the pitch P of screw mandrel, then in conjunction with the parameter area of subscribing, select modulus z, the number of teeth m of ratchet.The ratchet corresponding screw mandrel that rotates a circle rotates a circle, therefore every feeding one tooth of ratchet, the respective slide depth of cut is calculated as follows:
fmm/r=p/m
The adjusting of the utility model amount of feeding can be by workpiece end face the position of fixedly collision block 9 determine, as can be seen from Figure 2, when collision block 9 is moved to the left, driver plate 52 is large with block contact area, thereby cause promoting the ratchet anglec of rotation, become large, once promote the more number of teeth, the amount of feeding increases.Otherwise the amount of feeding can be reduced.Supposing to regulate rear each collision to drive ratchet to rotate the number of teeth is N, and respective slide tool feeding amount is as follows:
fmm/r=p/m×N
By the method, regulate the amount of feeding, can realize the separate machined of heavy boring and right boring, thereby reach drawing specification requirement.
