The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, present embodiment gear-hobbing machine slide plate rotating disk retaining mechanism, comprise slide plate 1, be arranged at the rotating shaft 2 on the slide plate 1 and be fixed on rotating disk 3 in the rotating shaft 2, also comprise being fixed on the rotating disk 3 and the gear 4 coaxial, be provided with the adjustable gap of axial distance 5 between the end face of described gear 4 and the slide plate end face with it; Also comprise be arranged on the gear 4 and with the coaxial arc groove 6 of gear 4, be connected the bolt 7 of gear 4 and slide plate 1 and be arranged on and be used to drive the screw drive mechanism that bolt 7 moves vertically on the slide plate 1, described bolt 7 is arranged in arc groove 6 and can reciprocatingly slides along arc groove 6.
In the present embodiment, rotating disk 3 and gear 4 are bolted to connection (not drawing among the figure), easy accessibility.Certainly in different embodiments, described rotating disk 3 and gear 4 also can adopt the mode that is made into integration to fix, and at this moment arc groove 6 just directly is arranged on the rotating disk 3.
In the present embodiment, described arc groove 6 is a T-slot, and itself and bolt 7 nose shapes are adaptive; Certainly in different embodiments, described arc groove 6 also can be the straight arc groove that groove width equates on depth direction, and the groove that holds bolt 7 heads is set on rotating disk 3 simultaneously, also can realize the purpose of this utility model.
The utility model gear-hobbing machine slide plate rotating disk retaining mechanism, under the screw drive mechanism lead-screw is pressed on gear state on the slide plate, gap between gear 4 and the slide plate 1 is eliminated, rotating disk 3 is locked, thereby strengthened the rigidity of rotating disk, made rotating disk in process, the rotating disk vibration reduces, and then the vibration of knife rest is reduced, can improve crudy.
As improvement to present embodiment, described screw drive mechanism comprises that cylinder body 8 is fixed on the oil cylinder on the slide plate 1, described bolt 7 passes the cylinder body 8 and the piston 9 of oil cylinder in mode sliding back and forth, and the end that described bolt 7 passes piston 9 is provided with the locking nut 10 that cooperates with piston 9 end faces.
In the present embodiment, described oil cylinder is an one-way cylinder, is provided with the disk spring 11 that promotes piston 9 between its piston nose and the cylinder body 8, and the front end of described piston is an end relative with locking nut 10.Certainly in different embodiments, oil cylinder also can be two-way cylinder, and the reciprocating motion of piston 9 all leans on hydraulic oil to drive, and also can realize the utility model purpose, but its control is complicated, and energy loss-rate present embodiment is big.
The utility model gear-hobbing machine with the operation principle of slide plate rotating disk retaining mechanism is:
