Detailed description of the invention
It is illustrated in figure 1 the boring template drive mechanism of the present invention, including the power shaft 2 be arrangeding in parallel and output shaft, transition axis 5 it is provided with between power shaft 2 and output shaft, power shaft 2 and transition axis 5 are rotationally connected with fuselage 1 by bearing respectively, the input of power shaft 2 is provided with driving pulley 16, this driving pulley 16 is connected by transmission band with driving motor, and power shaft 2 is connected by spline axially slidable duplicate gear 1, and duplicate gear 1 includes gear wheel one 17A and little gear one 17B.It is rotatably connected to triple gear 14 by bearing on transition axis 5, this triple gear includes the first gear 14A, the second gear 14B and the 3rd gear 14C, duplicate gear 1 is stirred along power shaft 2 position in axial sliding by a shift fork and is positioned by shift fork, when duplicate gear 1 axially slides to limit on the left position, gear wheel one 17A engages with triple gear the first gear 14A, duplicate gear 1 when sliding to limit on the right-right-hand limit position little gear one 17B engage with triple gear the second gear 14B.Being also associated with axially slidable duplicate gear 23 by spline on transition axis 5, duplicate gear 23 includes gear wheel two 3A and little gear two 3B, and the axle head of transition axis 5 is fixedly connected with transition gear 4.Output shaft includes the inner spline gear wheel shaft 11 of the hollow being rotationally connected with fuselage 1 by bearing, external splines boring bar axle 15 it has been in axial sliding connection in inner spline gear wheel shaft 11, external splines boring bar axle 15 can slide axially in inner spline gear wheel shaft 11, and external splines boring bar axle 15 one end is stretched out inner spline gear wheel shaft 11 outer end and connected boring die device.It is fixed with nut guide pin bushing 13 inside external splines boring bar axle 15 other end, the feed leading screw 8 coordinated with nut guide pin bushing 13 it is additionally provided with in external splines boring bar axle 15, feed leading screw 8 is connected by bearing with the interior axle head of inner spline gear wheel shaft 11, and feed leading screw 8 stretches out the external part of inner spline gear wheel shaft 11 and is rotatably connected to travelling gear 1 by bearing, travelling gear 1 engages with transition gear 4, travelling gear 1 is laterally provided with away break bar 7, walk break bar 7 with feed leading screw 8 by bonded, and walk break bar 7 and electromagnetic clutch is installed, to realize away break bar 7 and the synchronous axial system of travelling gear 1 or to separate.Inner spline gear wheel shaft 11 periphery is also fixedly connected with travelling gear 29, travelling gear 3 10 and travelling gear 4 12, and travelling gear 4 12 engages with the 3rd gear 14C of triple gear.Realization is stirred also by a shift fork in the position that slides axially of duplicate gear 23, and by this shift fork location duplicate gear 23 in the position of transition axis 5, when stirring shift fork and making duplicate gear 23 slide to limit on the left position, gear wheel two 3A engages with travelling gear 29, and when duplicate gear 23 slides to limit on the right-right-hand limit position, little gear two 3B engages with travelling gear 3 10.It addition, rotate for ease of manually regulation feed leading screw 8, feed leading screw 8 outer end is provided with square external part, and this square external part can connect easy-to-mount manual trip gear, and this manual trip gear can be handwheel, handle or spanner etc..
Following boring template action can be realized by the boring template drive mechanism of the present invention:
(1) low-rotate speed feeding forward: the little gear 17B of the duplex-gear 1 on power shaft 2 engages with the second gear 14 B in the triple gear 14 on transition axis 5, on transition axis 5, the gear wheel 3A in duplicate gear 23 engages with travelling gear 29, walk break bar 7 with travelling gear 1 by electromagnetic clutch synchronized links, now the rotating speed of feed screw mandrel 8 is less than nut guide pin bushing 13 and the rotating speed of external splines boring bar axle, and direction of rotation is consistent, Gu external splines boring bar axial advancement is given, again because power shaft duplicate gear 1 little gear one 17B engages with the second gear 14B in triple gear 14, so the axially front low-rotate speed feed motion of external splines boring bar；(2) fast rotating speed feeding forward: on power shaft 2, gear wheel one 17A of duplicate gear 17 engages with the first gear 14A in the triple gear 14 on transition axis 5, and remaining transmission situation is identical with the first situation；
(3) low-rotate speed feeding backward: little gear two 3B in the duplicate gear 23 on transition axis 5 engages with travelling gear three, it is identical that remaining transmission situation plants situation with (1st)；
(4) fast rotating speed feeding backward: on power shaft 2, gear wheel one 17A in duplicate gear 1 engages with the first gear 14A in the triple gear 14 on transition axis 5, little gear two 3B in duplicate gear 23 on transition axis 5 engages with the travelling gear 3 10 on output shaft, and remaining transmission situation is identical with the first situation.
(5) fast withdrawing backward: on power shaft 2, duplicate gear 17 less gear one 17B engages with the second gear 14B in the triple gear 14 on transition axis 5, and electromagnetic clutch does not works.At this moment only have nut guide pin bushing 13 and external splines boring bar axle 15 high-speed rotation, it is achieved boring bar fast withdrawing backward.
(6) manual trip gear being arranged on the square external part of feed screw mandrel 8, and makes away break bar 7 be off with travelling gear 1, the manual trip gear of positive and negative rotation, manual actuation external splines boring bar axle 15 seesaws.
The invention is not limited in above-described embodiment; such as; every on the basis of technical scheme disclosed by the invention; those skilled in the art is according to disclosed technology contents; need not performing creative labour and some of which technical characteristic just can be made some replacements and deformation, these are replaced and deformation is all in the scope of protection of the invention.
