Abstract
The invention relates to a ballscrew nut mounting structure which comprises a nut seat which is connected with a workbench and a screw nut which has a flange and penetrates through the nut seat, wherein a magnet is embedded in the nut seat or the flange of the screw nut, and the screw nut is connected onto the nut seat through a flange face and the magnet. The ballscrew nut mounting structure has a simple structure, and is convenient to install. During the ballscrew assembly, not only is the mounting precision ensured, but also the assembly requirement is simplified. Moreover, the ballscrew nut mounting structure also can be used as a protection device for preventing a machine tool from collision.
Description
Technical field
The invention belongs to field of machining, be specifically related to a kind of ball-screw nut mounting structure.
Background technology
Ball-screw is as the critical component of realizing the motion of lathe straight-line feed, and its assembly precision and fit have material impact to guide screw movement precision (linearity, positioning accuracy, stationarity).
The screw attachment that adopts transmission ball-screw nut flange and nut seat realizes the end face location, adopts the slight clearance of nut and nut seat endoporus to realize radial location.There is following shortcoming in this structure:
1) part processing precision require high, cost is high: nut and nut seat endoporus matched in clearance, to the requirement on machining accuracy of nut seat endoporus than higher, the cost height;
2) assembling process is complicated, and assembly precision is difficult to guarantee: in order to guarantee the stationarity of feed motion, during assembling, require than higher nut and nut seat endoporus axiality.Simultaneously, in order to guarantee the linearity of feed motion, require spigot surface on leading screw Up Highway UHW and the guide rail, the depth of parallelism of side spigot surface during assembling.These required precisions have strengthened the assembled in situ difficulty, are difficult to guarantee assembly precision.
3) security in the lathe running: be screwed the fit of nut and nut seat, when lathe generation car accident, nut and nut seat can't be thrown off, and bump damages workbench, and then cause the machine tool accuracy forfeiture.
Summary of the invention
The object of the present invention is to provide a kind of assembling simple, safety, and have the collision of preventing, the ball-screw nut mounting structure of the effect of protection workbench.
For achieving the above object; The technical scheme that the present invention adopts is: comprise the nut seat that is connected with workbench; And the feed screw nut that has flange that runs through nut seat, on the flange of nut seat or feed screw nut, being inlaid with magnet, feed screw nut is connected on the nut seat through flange face and magnet.
The installing hole of described nut seat is the external diameter 2-5 millimeter of the internal diameter of nut seat greater than feed screw nut.
The suction of described magnet is greater than dragging the required minimum force of workbench, the impulsive force that reaches less than collision.
Described magnet symmetric arrangement.
Described magnet is permanent magnet or electromagnet.
The present invention connects nut flange face and nut seat through magnet; Simplify the matching requirements of ball-screw; From fit on, when leading screw is installed, at first with on magnet inserted num seat or the nut flange; The end face of nut seat or nut flange placement magnet is polished, then nut seat is connected with mobile platform.Spigot surface on adjustment leading screw Up Highway UHW and the guide rail, the depth of parallelism of side spigot surface.Nut is pushed nut seat, and magnet connects nut flange and nut seat end face.The traditional relatively usefulness screw attachment feed screw nut and the mounting structure of nut seat, the present invention propose with magnet coupling nut and nut seat, simplified assembly technology.
From the lathe security, when car accident occurring under the lathe running status, active force is during greater than magnet suction, and nut flange and nut seat face opening have effectively been protected workbench.
