The specific embodiment
Shown in Fig. 1,2,3,4, the utility model comprises drive motors 1, and drive motors 1 is controlled fixed center gear 4 by cylindrical gear reducer 3, and fixed center gear 4 is by controlling swivelling tool-holder 6 with the fixing planetary gear 5 of worm shaft 16.Described swivelling tool-holder 6 is fixedly mounted on speed reducer output shaft 15, swivelling tool-holder 6 is provided with cutter head 9, cutter head 9 is installed in and drives on the movable knife bar 11 of screw mandrel 13 threaded engagement, on movable knife bar 11, be set with fairlead 10, between movable knife bar 11 and fairlead 10, be provided with feather key 12, drive screw mandrel 13 and worm gear 14 and be connected and fixed by key.Between described cylindrical gear reducer 3 and the speed reducer output shaft 15 mounting flange 17 is installed.Described drive motors 1 drives cylindrical gear reducer 3 by driving belt 2.Be fixed with thin-wall barrel geometrical clamp shell on the described swivelling tool-holder 6.Lower half shell 8 bodies of described thin-wall barrel geometrical clamp shell are longer, and the rear portion is provided with guide pile, and upper half-shell 7 is shorter, and housing lower half 8 passes through bolting with upper half-shell 7.
Both ends of the surface special cutting device of the present utility model is as shown in Figure 1, 2: the utility model can be divided into thin-wall barrel geometrical clamp shell and knife rest rotating mechanism two parts are formed.Thin-wall barrel geometrical clamp shell is divided into two halves up and down, and housing lower half 8 is longer, and the rear portion is provided with two groups of guide piles, to solve the length positioning requirements of two end face processing of thin-wall barrel; Upper half-shell 7 is very short, and is also comparatively light, adopts special bolt to fixedly connected with housing lower half 8, when cylinder part is installed, need unclamp bolt, take away upper half-shell 7, treat that cylinder part is in place after, refill upper half-shell 7, and use bolting, processed housing is fastened in the folder shell.The roundness of circular hole is guaranteed that by machining the out-of-roundness error is less than 0.2 millimeter in the last lower house.
The knife rest rotating mechanism is by drive motors 1, belt pulley, and the two poles of the earth cylindrical gear reducer 3 and swivelling tool-holder 6 etc. is partly formed.Wherein, swivelling tool-holder 6 is fixedly mounted on the cylindrical gear reducer output shaft 15, and by belt 2, gear drive is slowed down, and realizes that knife rest slowly runs.The internal structure of swivelling tool-holder 6 is by cutter head 9, fairlead 10, and movable knife bar 11, feather key 12 drives screw mandrel 13, worm gear 14, worm shaft 16, planetary gear 5 and swivelling tool-holder 6 etc. is partly formed.We fixedly mount a fixed center gear 4 on the shell of cylindrical gear reducer output shaft 15, when swivelling tool-holder 6 slowly runs, with the fixing planetary gear 5 of worm shaft 16, in the central gear revolution, rotation is ordered about worm shaft 16 and is rotated, and worm shaft 16 orders about worm gear 14 again and slowly runs; Worm gear 14 with drive screw mandrel 13 and link synchronously by key and rotate, with the movable knife bar 11 that drives screw mandrel 13 threaded engagement, can't rotate by fairlead 10 and feather key 12 constraints, when driving screw mandrel 13 and rotate, movable knife bar 11 can only stretch out or withdraws along axis direction.Like this, when swivelling tool-holder 6 uniform rotation, movable knife bar 11 and cutter head 9 slowly stretch out, and realize thin-wall barrel end face cutting from inside to outside; During the motor counter-rotating, movable knife bar 11 and cutter head 9 be slowly withdrawal again.
