Abstract
The invention relates to a longitudinal movement device for an image intensifier of a simulated locator. The longitudinal movement device comprises a longitudinal framework, wherein a linear guide rail and a ball screw pair are respectively arranged at one side of the longitudinal framework up and down, and the ball screw pair is driven by a driving motor and a gear to rotate in the longitudinal framework; a nut is arranged on the ball screw pair, and a connecting plate is arranged at the outer side of the nut; the nut rotates to drive the connecting plate to move left and right on the linear guide rail, and a longitudinal movement guide rod is fixedly arranged on the connecting plate; a linear bearing is arranged at a matched part of the longitudinal guide rod and a device body. The linear bearing replaces a sliding spline pair, so that the radial clearance is greatly reduced and the precision of linear movement is improved; the linear guide rail is used for balancing the torque generated by the weight of the image intensifier, so that a screw cannot bear a lateral force, and the impact of the stiffness of the screw on the precision of the linear movement is eliminated; the ball screw pair replaces a trapezoidal screw pair, so that the driving resistance is reduced.
Description
Technical field
The present invention relates to a kind of localization machine image amplifier, particularly relate to a kind of localization machine image amplifier lengthwise movement device.
Background technology
The lengthwise movement of image amplifier requires higher precision of rectilinear motion, ensures that the position of image amplifier relative longitudinal framing in any position in space does not deflect, the rectilinear motion before and after only producing.The Imaging enhanced lengthwise movement of traditional analog localization machine, trapezoidal screw is adopted to drive the mode of free-sliding spline pair to realize by connecting plate, the accuracy of rectilinear motion is subject to the stiffness effect of the glade plane space of free-sliding spline pair and trapezoidal screw pair very large, causes the precision of rectilinear motion very poor.
Summary of the invention
The object of this invention is to provide a kind of localization machine image amplifier lengthwise movement device, this apparatus structure is simple, and the mode that linear bearing and line slideway combine, improves the precision of rectilinear motion.
The object of the present invention is achieved like this:
A kind of localization machine image amplifier lengthwise movement device, it comprises longitudinal framing, longitudinal framing side arranges line slideway and ball wire bar pair up and down respectively, ball wire bar pair rotates under the drive of drive motors and gear in longitudinal framing, ball wire bar pair is provided with nut, is provided with connecting plate outside nut, and nut rotation drives connecting plate side-to-side movement on line slideway, connecting plate is fixed with lengthwise movement guide rod, the cooperation place of Der Laengslenker and body is provided with linear bearing.
The present invention achieves following technique effect: linear bearing substitutes free-sliding spline pair, substantially reduces the precision that radial clearance improves rectilinear motion; The moment of torsion that the weight that line slideway is used for balanced image booster produces, makes screw mandrel no longer by cross force, eliminates the rigidity of screw mandrel to the impact of the precision of rectilinear motion; It is secondary that ball wire bar pair replaces trapezoidal screw, decreases driving resistance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
See Fig. 1, a kind of localization machine image amplifier lengthwise movement device, it comprises longitudinal framing 1, longitudinal framing side arranges line slideway 4 and ball wire bar pair 3 up and down respectively, ball wire bar pair rotates under the drive of drive motors and gear 7 in longitudinal framing, ball wire bar pair is provided with nut 9, connecting plate 2 is provided with outside nut, nut rotation drives connecting plate side-to-side movement on line slideway, connecting plate is fixed with lengthwise movement guide rod 6, the cooperation place of Der Laengslenker and body 8 is provided with linear bearing 5.
Drive motors and gear 7 drive the screw mandrel of ball wire bar pair 3 to rotate, and nut 9 side-to-side movement of ball wire bar pair 3 also drives the guide rod 6 be fixed as one with image amplifier to make tandem and moves.The precision of the rectilinear motion of guide rod 6 has linear bearing 5 and line slideway 4 to ensure.The cooperation of the nut of connecting plate 2 and ball wire bar pair 3 is that the very large hole axle in gap coordinates, add the support of line slideway, can ensure that the active force that the total amount of image amplifier produces can not produce cross force on ball wire bar pair 3, thus the rigidity eliminating ball wire bar pair 3 is to the image of the precision of rectilinear motion of guide rod 6.
