The specific embodiment
The boring cutter of embodiment 1, present embodiment fine boring machine is fast to be transferred and micro-adjusting mechanism, its structure can be seen from Fig. 1～Fig. 3, it contains a band internal thread A who installs and external screw thread B on bed body 6 fine setting screw mandrel 3, one and the fast accent screw mandrel of the internal thread A engagement of fine setting screw mandrel 38, thread jacket 5 and this thread jacket with the external screw thread B engagement of fine setting screw mandrel 3 pass through screw 9 and tool rest 2 affixed one, the spring 7 that can eliminate thread pitch; Wherein finely tune screw mandrel 3 and comprise a bar 3a that under the restriction of pin 3d, can only rotate, an intermediate sleeve 3c who is connected with chute 3b ' with key 3b with this bar, and internal thread A and external screw thread B are separately positioned on the inner and outer wall of intermediate sleeve 3c, the pitch of internal thread A is greater than the pitch of external screw thread B; The fast accent has the locking device 4 of can be affixed with bed body 6 or throwing off on the screw mandrel 8.
The structure of locking device 4 can see from Fig. 1, Fig. 4～Fig. 5, and it contains one and is installed in and holds out against screw 4a in the body 6.This holds out against screw forward or reverse, can be locked motionless from the screw mandrel that circumferentially it held out against, transfers soon of fast accent screw mandrel 8; Unclamp perhaps that to hold out against screw 4a be rotatable fast accent screw mandrel 8.
When the depth of cut of micrometer adjustement boring tool, screw earlier and hold out against screw 4a fast accent screw mandrel 8 is maintained static, the bar 3a, the bar 3a that rotate fine setting screw mandrel 3 then promptly only rotate under the qualification of pin 3d, and drive intermediate sleeve 3c by key 3b and rotate; Intermediate sleeve is its internal thread A and fast screw-threaded engagement, its external screw thread B and thread jacket 5 engagements of transferring screw mandrel 8 in rotation, and key 3b and chute 3b ' allow it to move axially, 5 of thread jackets are done moving to the left or to the right vertically in this gear motion, thereby driven the tool rest 2 of one affixed, realized that the depth of cut of boring cutter 1 changes with it.
If the fine setting depth of cut, so that it changes from small to big, then clockwise rotate fine setting screw mandrel 3, key 3b drives intermediate sleeve 3c and clockwise rotates, because fast accent screw mandrel 8 locked can't drives, so intermediate sleeve 3c along screw thread A be moved to the left, 5 of thread jackets move right along screw thread B because pitch A is greater than pitch B, the synthetic rear thread overcoat 5 of two moving directions drives tool rests 2 and is moved to the left.This amount of movement is the pitch that the pitch of screw thread A deducts screw thread B, multiply by the rotation number of turns of intermediate sleeve 3c again.
When if the depth of cut is carried out coarse adjustment (being that the depth of cut changes greatly) greatly by ditty, then unclamp earlier and hold out against screw 4a, clockwise rotate fast accent screw mandrel 8 then, at this moment intermediate sleeve 3c is moved to the left along screw thread A, simultaneously thread jacket 5 is driven by intermediate sleeve and is moved to the left, and promptly is adjusted with the affixed tool rest of intermediate sleeve to put in place.Its amount of movement is the rotation number of turns that the pitch of screw thread A multiply by fast accent screw mandrel 8.
From Fig. 1 and Fig. 3, can see, transfer soon on the bar 3a of screw mandrel 8 and fine setting screw mandrel to have graduation mark respectively, with convenient faster to the depth of cut, regulate exactly.
The boring cutter of embodiment 2, present embodiment fine boring machine is fast to be transferred and micro-adjusting mechanism, its structure can be seen from Fig. 3, Fig. 6～Fig. 8, different is with embodiment 1 for it: its locking device 4 is the locking devices that have fast accent screw mandrel calibration location, and what this device was included in that one group of inner groovy 8a being provided with on the outer circle wall of fast accent screw mandrel 8 and one installs on bed body 6 can embed elastic component among the fast inner groovy 8a that transfers screw mandrel 8 with its elasticity.Wherein the elastic component among Fig. 3 and Fig. 4 is spring leaf 8b ', one end of this spring leaf is by screw 9 is fixed on the body 6, the other end has to be complementary with the shape of cross section of inner groovy 8a termination, this termination can embed among the inner groovy 8a who transfers screw mandrel 8 soon (state as shown in Figure 3) by its elasticity, so that transfer screw mandrel 8 to stop on this circumferential position soon, guarantee that its depth of cut is invariable in the boring cutter boring process, perhaps locking is fast transfers carry out of screw mandrel 8 to guarantee to finely tune.As rotating fast accent screw mandrel 8, then (state as shown in Figure 6) promptly deviate from elastic force, its termination that overcomes spring leaf 8b ' with revolving force from inner groovy 8a, and slip over from the outside wall surface of fast accent screw mandrel 8, rest at last with the corresponding to inner groovy of the depth of cut of required adjusting in.
Above-mentioned elastic component also can be to bump pearl 8b "; its structure can see from Fig. 7 and Fig. 8, this bump pearl comprise one be installed in the body 6 bump pearl body, one be installed in the little spring that bumps in the pearl body and energy under the little spring effect from bumping the external ball of stretching and being pressed into an inner groovy 8a of fast accent screw mandrel 8 of pearl.Imbed inner groovy by ball, can guarantee to transfer soon screw mandrel to rest on this feed position equally.Wherein Fig. 7 bumps ball in the pearl to embed state diagram, the depth of cut of locating among the inner groovy 8a under the little spring effect invariable, Fig. 8 transfers revolving force on the screw mandrel to overcome to bump pearl 8b soon " little spring power; the state diagram when making ball from inner groovy, slide to fast accent screw mandrel surface, that is be in the process that the depth of cut changes.
The locking device that has fast accent screw mandrel calibration location can not only lock fast accent screw mandrel and be convenient for people to finely tune the depth of cut, and is convenient for people to the quick depth of cut of coarse adjustment boring cutter exactly, and guarantees the invariable of the boring process depth of cut.
The fast accent with the structure of micro-adjusting mechanism of the boring cutter of embodiment 3, present embodiment fine boring machine can be seen from Fig. 2 and Fig. 7, it is with embodiment 1 or 2 different is: also increase a screw hole 2a and the regulating block 2b that can embed in the hole, boring cutter 1 place and have screw hole on it on its tool rest 2, have simultaneously on the sidewall of regulating block 2b and hold out against screw 4a.By the screw hole 2a that increases newly on the tool rest 2 and the screw hole among the regulating block 2b, present embodiment mechanism can be fastened on horizontal boring cutter sheet 1 ' on the tool rest with two screws at least, thereby carry out boring processing with horizontal boring cutter sheet 1 '.
From Fig. 7, also see, have simultaneously on the sidewall of regulating block 2b and hold out against screw 4a, so that the boring of this horizontal boring cutter sheet 1 ' processing is more reliable and more stable.
