The hole-boring and interior-angle-chamfering mechanism is characterized in that a screw rod body is arranged in a spindle hole of a boring head which is provided with a key groove. The axial extending length of a cutter bar is adjusted through a round nut A, the cutter bar is connected with an eccentric shaft through a radial feeding pin, an annular groove which is 90 degrees in circumference is arranged on the eccentric shaft at a position where the radial feeding pin is arranged, and accordingly the cutter bar can rotate at 90 degrees in the eccentric shaft. Simultaneously, the eccentric shaft is further connected with a hole of a spiral groove through a shift pin, and the spiral groove is arranged on the screw rod body. A bearing sleeve arranged on an outer ring of a thrust ball bearing is tightly attached to a guide sleeve base, the eccentric shaft moves relative to the screw body at the axial direction, the screw rod body is provided with the spiral groove, the shift pin forces the cutter bar to rotate in an eccentric hole to lead a tool nose to generate radial feeding during the process that the tool nose rotates around the axes of the screw rod body, and accordingly the movement of interior-angle chamfering is completed. The hole-boring and interior-angle-chamfering mechanism completing the hole-boring process and the interior-angle- chamfering process at one station has the advantages of completing the hole-boring process and the interior-angle-cutting process at one station, shortening machining time and simplifying processes. A rough-fine composite cutter is adopted, and accordingly cutting effect can be guaranteed.

Accompanying drawing 1 is the structural representation of the bore hole mechanism of falling the interior angle.
In the accompanying drawing 1 is the screw rod body, the 2nd, and A round nut, the 3rd, spring, the 4th, eccentric shaft, the 5th, B round nut, the 6th, back nut, the 7th, bearing holder (housing, cover), the 8th, guide bracket cover, the 9th, cutter head, the 10th, knife bar, the 11st, thrust ball bearing, the 12nd, the right lid of spring, the 13rd, dial and ship and resell on another market, the 14th, radial feed pin, the 15th, spring left side lid, the 16th, C round nut
The specific embodiment
Contrast accompanying drawing 1, its structure is that screw rod body 1 is installed in the spindle hole of the boring head of being with keyway, axial extension elongation by two the A round nuts that can lock, 2 adjusting knife bars, knife bar connects with eccentric shaft 4 by radial feed pin 14, the annular groove of 90 ° of girths is arranged in the position that eccentric shaft 4 is installed radial feed pin 14, can make knife bar 10 half-twist in eccentric shaft; Simultaneously eccentric shaft 4 again by dial ship and resell on another market 13 with screw rod body 1 on have the spiral fluted hole and be connected; Mechanism of the present invention does not only rotate and cutter head 9 has axial feed before bearing holder (housing, cover) 7 is run into guide pin bushing seat 8, and knife bar 10 and eccentric shaft 4 just can't axial feeds after unit head is run into guide pin bushing seat 8, bearing holder (housing, cover) 7 on thrust ball bearing 11 outer rings is close to guide pin bushing seat 8, screw rod body 1 still have march forward to, eccentric shaft 4 relatively moves axial the generation with screw rod body 1 like this, owing to have helicla flute on the screw rod body 1, dialling ships and resell on another market 13 just forces knife bar 10 to rotate in eccentric orfice to make point of a knife produce radial feed in screw rod body 1 axis turning course, finish the action of falling the interior angle, after processing puts in place, unit head is return fast, knife bar 10 just oppositely is retracted into reset condition along former road, finishes processing request.
Spring 3 is on eccentric shaft 4, the left end of spring 3 has spring left side lid 15, the right-hand member of spring 3 has the right lid 12 of spring, in sleeve mechanism, spring 3 is also being undertaken the effect of offsetting keyhole cutting axial force except playing eccentric reset response, too small as spring 3 strength, certainly will cause knife bar 10 vibrations and influence crudy, even cause the failure of this process; Crosses then assembling difficulty by force as spring 3 elasticity, and be difficult to be compressed to the spiral stroke, so the basic parameter of spring 3 is:
Steel wire diameter d=φ 6; Pitch T=20mm
Mean diameter of coil D=φ 50; Number of total coils N=12;
Free state length overall L=240mm;
Assembling back length L 1=192mm; Decrement Δ=48mm; Individual pen deflection fsd=4mm;
Deformation force Fs=fsd*kd=4*102=408N
The bore hole mechanism of falling the interior angle is installed on the unit head, unit head is installed on the nc sliding table, job order is: F.F., worker advance 1 (bore hole), the worker advances 2 (interior angles), rewind down, and work speed is controlled by nc sliding table, advance a little to use near the switch signalling the worker to make the servomotor action.If when falling the interior angle still is the bore hole feed speed axially, then radial feed speed is very low, and the worker advances chronic.Therefore under the prerequisite of selecting suitable cutting output for use, axial velocity is improved, radial velocity is improved.
When transferring the worker to by F.F., advances on slide unit, employing makes the servomotor action near switching signal, the worker advances length and is regulated by the length of signal generation piece, after in case bore hole is finished like this, axial feed just enters the F.F. state and falls interior angle, processing is return later fast, reaches the suitable purpose of radial feeds simultaneously of saving time.
The workpiece blank surplus has deviation than big and position, can cause cutting effect not satisfactory, roughness does not reach requirement, then knife bar can be made another kind of form, adopt thick right boring compound tool: to φ 14.4, surplus is little and even when allowing B cutter head right boring φ 15 with the hole heavy boring for the A cutter head, screw 1 is used for regulating bore diameter among the figure, screw 2 is a trip bolt, and is in order to compress cutter head, better through cutting effect like this.It should be noted that: dial and to ship and resell on another market unsuitable excessively with the spiral fluted gap, otherwise knife bar may have the withdrawing trace when retreating and influence surface quality.
