Abstract
The utility model relates to a structure for driving eccentric-sleeve used for roller grinder grinding wheel main shaft. The driving eccentric sleeve of it drives the feed of the grinding wheel, which has higher sensitivity and higher precision of the ground work piece. The utility model is characterized in that: it comprises a numerical control motor and a swinging link, the numerical control motor swing joints with a worm which engages with a worm gear sleeved on a ball screw rod which is screwed with a feed screw nut mounted on a linear rolling track pair; one end of the swinging link is a fork buckling the eccentric sleeve, and its other end is pressing equipped on the feed screw nut, and the middle part of the swinging link connects with the piston rod of the cylinder.
Description
(1) technical field
The utility model relates to the parts of roll grinder, is specially the drives structure of roll grinder grinding wheel spindle with eccentric bushing.
(2) background technology
The grinding wheel spindle of roll grinder is installed on the mill frame, and described mill frame is installed on slide plate, between described mill frame and the described slide plate cylindrical slideway is set, and described slide plate places lathe bed.During the grinding machine roll, the mill frame adheres to does low-angle rotation along cylindrical slideway when slide plate moves under the drive of driving mechanism on lathe bed, thereby realize camber grinding.Because the weight of mill frame is big, inertia was big when the mill frame drove the emery wheel feeding, poor sensitivity, and the workpiece accuracy that grinding goes out is also poor.
(3) summary of the invention
At above-mentioned shortcoming, the utility model provides the drives structure of a kind of roll grinder grinding wheel spindle with eccentric bushing, and under the driving of eccentric bushing driving mechanism, eccentric bushing drives the emery wheel feeding, and its sensitivity is higher, and the workpiece accuracy of grinding is also higher.
Its technical scheme is such: it is characterized in that: it comprises numerical-control motor, fork, described numerical-control motor rotating shaft connects worm screw, described worm and wheel engagement, described worm gear set is loaded on ball screw, and described ball screw and feed screw nut screw togather, and described feed screw nut is installed on straight-line rolling guide set, one end of described fork is a prong, described prong fastens eccentric bushing, and the other end of described fork press-fits in described feed screw nut, and the middle part of described fork is connected with the piston rod of oil cylinder.
Eccentric bushing of the present utility model is set in grinding wheel spindle, under the driving of driving mechanism, eccentric bushing drives grinding wheel spindle and does low-angle rotation, short-range skew is done in the axle center of grinding wheel spindle, thereby realize camber grinding to workpiece, the entire mechanism compact conformation, sensitivity is good, and precision is higher when driving the grinding wheel spindle rotation, thereby has avoided existing roll grinder, it drives the mill frame by drives structure and rotates, realize camber grinding, and the weight of mill frame is big, inertia was big when the mill frame drove the emery wheel feeding, the shortcoming that the workpiece accuracy that poor sensitivity, grinding go out is relatively poor.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) specific embodiment
See Fig. 1, the utility model comprises numerical-control motor 2, fork 1, numerical-control motor 2 rotating shafts connect worm screw 4, worm screw 4 and worm gear 3 engagements, and worm gear 3 is set in ball screw 5, ball screw 5 screws togather with feed screw nut 7, feed screw nut 7 is installed on straight-line rolling guide set 8, and an end of fork 1 is a prong, and prong fastens eccentric bushing 10, the other end of fork 1 press-fits in feed screw nut 7, and the middle part of fork 1 is connected with the piston rod of oil cylinder 6.Describe course of action of the present utility model below in conjunction with Fig. 1: cnc mechanism control motor 2 rotates on request, drive ball screw 5 and rotate through worm gear 3, worm screw 4, because ball screw nut 7 has limited the free degree by straight-line rolling guide set 8, so when screw mandrel 5 rotates, ball screw nut 7 will move up and down along straight-line rolling guide set 8, thereby driving eccentric bushing fork 1 swings up and down, the eccentric bushing revolution, make grinding wheel spindle 9 obtain to drive closely or recess the displacement X of workpiece, thereby in whole roll surface length, realized camber grinding.Oil cylinder 6 can make emery wheel recess the surface of workpiece immediately, is power-off protection mechanism.
Claims (1)
