For a short time, go up line slideway 304 installation directions and little line slideway 305 installation directions are vertical mutually down, that is to say that the little slip direction that goes up line slideway 304 is vertical mutually with the slip direction of little line slideway 305 down.Tail rod 5 is a cylindrical bar, its diameter is by the modulus of quilt quenching gear, decisions such as the number of teeth, when quenching, tail rod 5 is pressed on by (as Fig. 6) on the flank of tooth of quenching gear tooth slot, tail rod 5 is fixedly connected on the little lower skateboard 303 of little cross slid platform 3 by pole 4, inductor block 6 is fixedly connected on the lower skateboard 103 of grand cross slide unit by inductor block support 7, the shape of cross section of inductor block 6 is with consistent by the teeth groove of quenching gear, even with flank of tooth maintenance gap when quenching, in the present embodiment, pole 4 is provided with internal tooth tail rod 501 and external tooth tail rod 502, inductor block support 7 is provided with corresponding internal tooth inductor block 601 and external tooth inductor block 602, internal tooth tail rod 501 carries out hardening step with 601 teamworks of internal tooth inductor block to ring gear 15, and external tooth tail rod 502 carries out hardening step with external tooth inductor block 602 teamwork external gear wheels 16.
Principle of work of the present invention:
As Fig. 6 and Fig. 1,2,3,4, shown in 5, moving of grand cross slide unit 1 both direction respectively by cylinder 2 and equalizing spring 8 controls, the little cross slid platform 3 of device on grand cross slide unit 1 reaches down by above-mentioned upper screw rod nut body 306, and leading screw and nut mechanism 307 control both directions move, tail rod 5 is fixedly connected on the little cross slid platform 3 by pole 4, inductor block 6 is fixedly connected on the grand cross slide unit 1 by inductor block support 7, adjusting little cross slid platform 3 can make tail rod 5 shift to and inductor block 6 relative suitable positions, promptly when inductor block 6 in the central position of teeth groove and suitable with the spacing of the flank of tooth, tail rod 5 holds out against on the flank of tooth of adjacent sheaves, and this moment, tail rod 5 was fixed with the relative position of inductor block 6.When the quenching of finishing a teeth groove, enter when next teeth groove quenched, because the possible error of division, the physical construction gap of worktable and the error of gear itself causes the position of this teeth groove and the position of a last teeth groove that certain deviation is arranged, keep certain pressure that tail rod 5 is held out against on the flank of tooth of adjacent sheaves by cylinder 2, because the lower skateboard 103 of grand cross slide unit 1 floats, thereby guarantee inductor block 6 and even by the spacing between the quenching teeth groove flank of tooth between two equalizing springs 8.
Adjustment operating process of the present invention:
1. coarse adjustment: at first crawl starts the travel mechanism 17 of lathe, allow inductor block 6 arbitrary teeth groove near gear rings, but do not contact teeth groove, make inductor block 6 from 3 millimeters of tooth tops with interior position, guarantee that simultaneously tail rod 5 lower ends stretch out 20 millimeters of workpiece belows,, regulate worktable if inductor block is not aimed at teeth groove, make worktable at a slow speed clockwise or be rotated counterclockwise, guarantee that inductor block 6 just in time aims at teeth groove; Regulate little cross slid platform 3 simultaneously, if tail rod 5 is not aimed at contiguous teeth groove, regulate tail rod 5 by finely tuning little cross slid platform 3, assurance tail rod 5 is also just in time aimed at adjacent teeth groove, the travel mechanism 17 of manual regulation lathe, make inductor block 6 enter teeth groove, regulate little cross slid platform 3 simultaneously and make tail rod 5 lean addendum flank, two equalizing springs 8 are at meta at this moment, and lower skateboard 103 is in equilibrium state, cylinder 2 is not ventilated, and cylinder 2 piston rods are in retracted state.
2. fine setting: after adjusting, cylinder 2 ventilations, the pressure of cylinder 2 is pressed on the flank of tooth tail rod 5, regulate little cross slid platform 3, tail rod 5 is all around moved, and inductor block also moves thereupon, and the gap that makes the inductor block 6 and the flank of tooth is in 0.1 millimeter, inductor block can not contact Tooth during adjusting, in order to avoid inductor block 6 stress deformations.After mixing up, write down the machine tool control system parameter of this moment, be the quenching starting point.The air pressure adjustment of cylinder 2 at 0.3～0.4MPa, is guaranteed that tail rod 5 all the time on the flank of tooth near teeth groove, guarantees tail rod 5 simultaneously not because of stressed excessive the distortion, and the gap of inductor block 6 and the teeth groove flank of tooth is all the time in 0.1 millimeter.After above-mentioned adjustment is finished, because tail rod 5 locks with the relative position of inductor block 6, when next teeth groove is quenched, if there is certain deviation the position of this teeth groove and a last teeth groove, keep certain pressure that tail rod 5 is held out against on the flank of tooth of adjacent sheaves by cylinder 2, the lower skateboard 103 of grand cross slide unit 1 floats between two equalizing springs 8, thereby guarantee inductor block 6 and even, thereby guarantee that the inductor block 6 and the gap tracking of the flank of tooth remain in 0.1 millimeter by the spacing between the quenching teeth groove flank of tooth.
The present invention not only is used for the gear quenching lathe, can also be used in other similar lathes.
