Background technology
Existing gear shaving machine can only make cutter frame mechanism be rotated motion, can not realize simultaneously rotatablely moving and axial back and forth movement is fastened coexistence at same axle.
Summary of the invention
Technical problem to be solved by this invention provides a kind of driving box device of gear shaving machine, and it can be fastened at same axle and realize rotatablely moving and axial back and forth movement.
For solving the problems of the technologies described above, the technical solution of the driving box device of gear shaving machine of the present invention is:
Comprise drive motors, the output shaft of drive motors connects the driving worm screw, drives worm screw and is meshed with the driving worm gear; Driving worm gear is fixedly set on the driving splined shaft; Drive on the splined shaft and be arranged with hollow spline leading screw, be set with the lifting worm gear on the hollow spline leading screw, promote worm gear and be meshed with the lifting worm screw; Promote worm screw and connect the output shaft that promotes motor; Be provided with the gap between said hollow spline leading screw and the driving splined shaft, make the spinning movement of driving splined shaft and the spinning movement mutually noninterfere of hollow spline leading screw; Be movably set with feed screw nut on the hollow spline leading screw, feed screw nut is fixedly connected slide; An end that drives splined shaft is provided with driving bevel gear; Drive motors drives the splined shaft rotation through driving worm screw and driving worm gear drives, can drive the driving bevel gear rotation; Driving bevel gear flexibly connects with driving splined shaft through spline, can drive driving bevel gear when driving the splined shaft rotation and rotate together, and driving bevel gear is when axis direction moves up and down, and it is motionless to drive splined shaft; Promote motor through promoting worm screw and promoting the hollow spline leading screw rotation of worm gear drives, feed screw nut is moved along hollow spline leading screw up and down, feed screw nut can drive driving bevel gear through slide and move up and down.
Said hollow spline leading screw and the coaxial setting of driving splined shaft.
The lower end of said driving splined shaft is provided with spline mechanism; Driving bevel gear is provided with and drives the endoporus that the splined shaft end surface shape matches.
The technique effect that the present invention can reach is:
The present invention adopts two cover worm and gear transmissions and a cover ball-screw drive mechanism, and this three covers fine structure is carried out perfect adaptation, thereby has realized rotatablely moving and axial back and forth movement is fastened coexistence at same axle; And the overall structure operation is highly stable; Safety, reliable, noise is extremely low.

The specific embodiment
As shown in Figure 1, the driving box device of gear shaving machine of the present invention comprises drive motors 4, and the output shaft of drive motors 4 connects driving worm screw 3, drives worm screw 3 and is meshed with driving worm gear 2; Driving worm gear 2 is fixedly set on the driving splined shaft 1;
Drive on the splined shaft 1 and be arranged with hollow spline leading screw 5, be set with on the hollow spline lead screw pair 5 and promote worm gear 6, promote worm gear 6 and be meshed with lifting worm screw 12; Promote worm screw 12 and connect the output shaft that promotes motor 11;
Hollow spline leading screw 5 and the 1 coaxial setting of driving splined shaft are provided with the gap between hollow spline leading screw 5 and the driving splined shaft 1, make the spinning movement of driving splined shaft 1 and the spinning movement mutually noninterfere of hollow spline leading screw 5;
Be movably set with feed screw nut 7 on the hollow spline leading screw 5, feed screw nut 7 is fixedly connected slide 9;
Drive splined shaft 1 and be arranged in the drive case 8, drive splined shaft 1 and flexibly connect through bearing and drive case 8; An end that drives splined shaft 1 stretches out drive case 8, and feed screw nut 7 and slide 9 are arranged at outside the drive case 8;
An end that drives splined shaft 1 is provided with driving bevel gear 10;
Driving bevel gear 10 flexibly connects through spline and driving splined shaft 1; Can drive driving bevel gear 10 when driving splined shaft 1 rotation and rotate together, and driving bevel gear 10 is when axis direction moves up and down, driving splined shaft 1 is motionless;
The lower end that drives splined shaft 1 is provided with spline mechanism; Driving bevel gear 10 is provided with the endoporus that matches with the end surface shape that drives splined shaft 1; Driving splined shaft 1 realizes and being connected of driving bevel gear 10 through spline mechanism; Driving splined shaft 1 both can drive driving bevel gear 10 and be rotated, and can also in the spline endoporus of driving bevel gear 10, slide up and down;
Driving bevel gear 10 flexibly connects through bearing and slide 9.
Operation principle of the present invention is following:
Drive motors 4 drives 2 rotations of driving worm gear through driving worm screw 3, makes to drive splined shaft 1 rotation; Drive splined shaft 1 and drive driving bevel gear 10 rotations, thus can drive installation in the cutter frame mechanism work of slide 9 bottoms;
Promote motor 11 and drive 12 rotations of lifting worm screw, and then make 6 rotations of lifting worm gear, promote hollow spline leading screw 5 rotations of worm gear 6 drives, the hollow spline leading screw 5 in feed screw nut 7 edges is moved up and down; Feed screw nut 7 drives slide 9, driving bevel gear 10 and cutter frame mechanism and pumps together, thereby realizes the shave action.
