The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and example.
As shown in Figure 1.
A kind of cutter head mechanism for deep hole boring, comprise the rotary head body 18 and the rotary head 17 that link to each other with lathe headstock, machine tool chief axis I is arranged in rotary head body 18, rotary head 17 is installed on the end that machine tool chief axis I stretches out rotary head body 18, the worm-wheel shaft II parallel with machine tool chief axis I is installed in described rotary head body 18, worm gear 5 is installed on the worm-wheel shaft II, worm gear 5 is meshed with worm screw 6, worm screw 6 links to each other with the worm drive device, the worm drive device can adopt buncher, stepless speed change device or step speed change device, and can realize numerical control or programming Control; On main shaft I, the both sides of worm gear 5 are separately installed with primary pinion 1 and final stage gear 10, final stage gear 10 is a duplicate gear with bevel gear wheel 11; Primary pinion 1 and first gear 2 engagements that are installed in worm-wheel shaft II one end, final stage gear 10 and second largest gear 9 engagements that are installed in the worm-wheel shaft II other end, the first gear 2 and first pinion 3 are duplicate gear, the second largest gear 9 and second pinion 8 are duplicate gear, first pinion 3 and 4 engagements of first planetary gear, second pinion 8 is meshed with second planetary gear 7, first planetary gear 4 and second planetary gear 7 are installed in the two ends of the planet axis III that passes worm gear 5 respectively, and planet axis III is positioned at the side of worm-wheel shaft II and in parallel; Bevel gear wheel 11 and bevel pinion 12 engagements, bevel pinion 12 is installed on the end of screw mandrel 16, screw mandrel 16 is installed in the rotary head 17, feed screw nut 15 is installed on the screw mandrel 16, feed screw nut 15 links to each other with cutter 14, the guide end of cutter 14 is installed in the tool guide 13, and tool guide 13 is installed on the end face of rotary head 17.As shown in Figure 1.
During concrete enforcement, described feed screw nut 15 also can adopt following mechanism to be achieved with being connected of cutter, be about to feed screw nut 15 directly with can only link to each other as the slide block that straight line moves, cutter 14 links to each other with slide block, slide block is installed in the tool guide 13, and tool guide 13 is installed on the end face of rotary head 17.
In addition, under the situation of installing space permission, the transmission mechanism of planetary gear also can adopt following method to be realized: described primary pinion 1 and first gear 2 engagements that are installed in worm-wheel shaft II one end, final stage gear 10 and second largest gear 9 engagements that are installed in the worm-wheel shaft II other end, first gear 2 is directly meshed with first planetary gear 4, second largest gear 9 directly is meshed with second planetary gear 7, first planetary gear 4 and second planetary gear 7 are installed in the two ends of the planet axis III that passes worm gear 5 respectively, and planet axis III is positioned at the side of worm-wheel shaft II and in parallel.
Buncher (or other have the level, stepless drive unit, down together) when not working, the power that main motor is defeated by machine tool chief axis is divided into two-way, and one tunnel direct driven rotary cutterhead 17 rotates, and makes the cutter 14 (hole boring cutter) that is installed on the tool guide 13 do gyration; The transmission of fixed axis gear 1,2,3 and planetary gear 4,7 and fixed axis gear 8,9,10 is then passed through on another road, drive bevel gear wheel 11, bevel pinion 12, at this moment, bevel gear wheel and machine tool chief axis rotate synchronously, and the rotation of bevel pinion is driven by the speed discrepancy between bevel gear wheel and the machine tool chief axis, be under zero the situation at speed discrepancy, bevel pinion does not produce gyration, just bevel pinion 12 and screw mandrel 16 have only the rotation around the machine tool chief axis axis, no rotation, thereby the no radial feed motion of cutter 14 (knife rest and feed screw nut 15).
In buncher when work,, power drives planetary gear 4,7 around worm-wheel shaft II revolution through worm screw 6, worm gear 5, and is synthetic with the power of machine tool chief axis I, produces the detour rotation of star wheel series axle of planetary gear 4,7 simultaneously, makes system form resultant motion.At this moment, bevel gear wheel 11 produces speed discrepancy with machine tool chief axis I, drives bevel pinion 12 and rotates, and rotates thereby drive screw mandrel 16, by feed screw nut 15, forms the radial feed motion of borer 14.
Rotatablely move by rotary head 17, the axial feed motion of motion of the radial feed of borer 14 and workpiece (workbench, see Fig. 2), adopt Numeric Control Technology can realize that the different continuous axial feed motions with workpiece (workbench) of boring cutter different radial feeds continuously motion are synthetic, process with the boring of the difformity deep hole that satisfies large-size pivoting support.
Example recited above only is the description of preferred implementation of the present invention; be not that design of the present invention and scope are limited; do not breaking away under the design concept prerequisite of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
