Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technological scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Fig. 1 is structural representation of the present invention, the present invention proposes a kind of automatic reversing mechanism for plug tapping machine, it is characterized in that, comprise output shaft 2, input shaft 8, jack shaft 9, cylinder 3, input shaft 8 is provided with input shaft gear 7, jack shaft 9 is provided with countershaft-gear 1, countershaft-gear 2 11, output shaft 2 is provided with output shaft gear 15, input shaft 8 to be meshed with countershaft-gear 1 by input shaft gear 7 and to be connected, jack shaft 9 is connected with output shaft gear 15 by countershaft-gear 2 11, the external splines 16 that commutates is provided with between output shaft 2 and output shaft gear 15, the bottom of cylinder 3 is provided with shifting fork bar 4, fork plate 5, connector element 6, and shifting fork bar 4 is connected with fork plate 5, and fork plate 5 is connected with connector element 6, and connector element 6 is connected with commutation external splines 16.
Be provided with idle pulley 12 between output shaft gear 15 and countershaft-gear 2 11, output shaft gear 15 is connected with countershaft-gear 2 11 by idle pulley 12; Idle pulley 12 inside is provided with idler shaft 14; Sliding bearing 1 is provided with between idle pulley 12 and idler shaft 14; Sliding bearing 2 17 is provided with between commutation external splines 16 and output shaft 2; Output shaft 2 is provided with the belt wheel 1 of outside transferring power; Input shaft 8 be externally connected to coupling.
Working principle of the present invention: the piston of cylinder 3 is positioned at stroke lower end, shifting fork bar 4 drives fork plate 5 and connector element 6, make input shaft 8 lead to external splines with output shaft 2 to be directly connected with spline housing, now power is directly delivered to output shaft 2 by input shaft 8, thus transmission of power is gone out (in this process by band movable belt pulley 1, output shaft gear 15 dallies on sliding bearing 2 17 with commutation external splines 16, not transferring power); When the piston of cylinder 3 is positioned at stroke upper end, shifting fork bar 4 drives fork plate 5 and connector element 6 up, input shaft 8 departs from output shaft 2 and is directly connected, now power input is transported to input shaft 8 by coupling and drives input shaft gear 7 to operate, then being transmitted by gears meshing drives countershaft-gear 1, jack shaft 9, countershaft-gear 2 11 to operate successively, and countershaft-gear 11 drives idle pulley 12 to drive output shaft gear 15 to operate by gears meshing transmission; So, the turn to belt wheel 1 when with the piston of cylinder 3 being positioned at stroke lower end of output shaft 2 with movable belt pulley 1 turns to contrary, realizes automatic reverse.
