Abstract
The utility model discloses a high-order curve automatic grinding device for a heavy CNC roll grinder, which comprise a swing link, a fully-digital AC servo motor and a reducer, the rotation of a ball bearing screw pair and the positioning of a nut sleeve realized by a guide bar realize the linear longitudinal movement of the nut sleeve. Furthermore, the transmission is sensitive; one end of the swing link precisely moves up and down along with the nut sleeve without swinging to the left and right, thereby realizing the high-precision back and forth microfeed or withdrawal of a main shaft arranged in an eccentric sleeve. Therefore, the high-order curve automatic grinding device can greatly enhance grinding precision.
Description
Technical field
The utility model relates to a kind of heavy type numerically-controlled roll grinding machine high order curve automatically grinding device structure, is used for the grinding of roller surface bus or special high order curve of grinding, and is smooth with the sheet material of guaranteeing to roll out, and accurately controls template.
Background technology
At present, the high order curve grinding attachment of roll grinder all is to adopt static pressure eccentric bushing structure (interior dress dynamic and static pressure principle axis shafting), drive ball screws and the fork that is loaded on the eccentric bushing drives eccentric interplanting small angle oscillation by AC servo motor through two helical pitch worm reduction boxs, make the grinding wheel spindle that is loaded in the static pressure eccentric bushing do the no gap of trace and cut (or withdrawing from) feeding with respect to roll surface.This feeding and planker (referring to the Z axle, perpendicular motion) feeding is mutually compound according to specific requirement, goes out various high order curves in roller surface (generatrix direction) grinding.But use two helical pitch worm and gear transmissions easy to wear, cause its gap big, transmission is insensitive, moreover its fork is guiding not, cause in grinding process the stressed back of eccentric bushing easily swing (refer to swing, this direction is vertical with exit axis with the feeding of main shaft), thus cause grinding accuracy not high.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of heavy type numerically-controlled roll grinding machine high order curve automatically grinding device, and this device can make fork can not swing, the grinding accuracy height.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of heavy type numerically-controlled roll grinding machine high order curve automatically grinding device, comprise fork, the digital ac servo motor and speed reducer, the power of digital ac servo motor is exported to reductor, be provided with a shaft coupling (flexibility), the shaft coupling power intake connects reductor power output, the shaft coupling clutch end connects the ball wire bar pair power intake, freely mesh by screw thread on the ball wire bar pair and be arranged with a nut sleeve, be fixed with one again and be guide post longitudinally, guide post is provided with a location slide block, nut sleeve is fixed on positioning sliding block, nut sleeve can go up under the rotation of ball wire bar pair accurately like this, following straight line moves, be that nut sleeve realizes by the guide post location, following straight line moves, fork places above the nut sleeve away from an end of eccentric bushing, fork is provided with balancing weight again away from an end of eccentric bushing, thereby making fork one end can lean against the nut sleeve upper surface follows nut sleeve and moves up and down, make it to drive the low-angle swing of eccentric interplanting, thereby make the main shaft that is loaded in the eccentric bushing realize high-precision front and back microfeed or withdraw from.
Further technical scheme of the present utility model is:
Positioning sliding block is made up of two eccentric cam bearings, the stiff end of two the eccentric cam bearings nut sleeve that is connected, the guide post condensing tube tongs is located in the scroll end of two eccentric cam bearings, by adjusting the off-centre of two eccentric cam bearings, make the scroll end of two eccentric cam bearings clamp guide post.
Fork is provided with camshaft bearing away from an end of eccentric bushing, and the rolling surface of camshaft bearing places above the nut sleeve, can reduce like this both contact-making surfaces wearing and tearing.
The beneficial effects of the utility model are: rotation by ball wire bar pair and nut sleeve are by the location of guide post, realize that the nut sleeve straight line moves up and down, and transmission sensitivity, fork one end is followed nut sleeve and is precisely moved up and down, and phenomenon can not occur swinging, thereby make the main shaft that is loaded in the eccentric bushing realize high-precision front and back microfeed or withdraw from.Therefore the utility model can increase substantially grinding accuracy.
