Abstract
A kind of auxiliary support apparatus preventing screw mandrel sagging, comprise the workbench for processing guide rail workpiece, workbench is provided with the pull bar of sliding guides workpiece, pull bar is fixed on sliding seat by holder, sliding seat is arranged on rail plate, rail plate is installed on supporting seat, the screw mandrel that on supporting seat, mounted motor drives, and screw mandrel is connected on sliding seat by feed screw nut; Supporting seat is provided with support cylinder, the piston rod of support cylinder is provided with the back-up block be supported on screw mandrel.This structure is supported on below screw mandrel by the back-up block supported on cylinder, prevents screw mandrel sagging, thus screw mandrel can be avoided be out of shape, not whipping when guaranteeing the High Rotation Speed of screw mandrel, thus protects the steady and precision of positive working table movement.
Description
Technical field
The utility model relates to guide rail process equipment, particularly relates to a kind of auxiliary support apparatus preventing screw mandrel sagging.
Background technology
At present added to guide rail man-hour, because the length of guide rail is longer, some longer guide rail reaches more than 5 meters, and guide rail needs the screw mandrel sliding guides of corresponding length in processing, because screw mandrel length is long, the zone line of screw mandrel can be sagging, produces whipping, can only moving at a lower rate of workbench when causing screw mandrel to rotate.Simultaneously cause screw mandrel to be out of shape after Long-Time Service, thus cause that movement velocity is low, low precision.
Utility model content
The utility model will solve above-mentioned prior art Problems existing, provides a kind of auxiliary support apparatus preventing screw mandrel sagging, can avoid screw mandrel sagging deflections, and does not affect screw mandrel use.
The utility model solves the technical scheme that its technical problem adopts: this auxiliary support apparatus preventing screw mandrel sagging, comprise the workbench for processing guide rail workpiece, workbench is provided with the pull bar of sliding guides workpiece, pull bar is fixed on sliding seat by holder, sliding seat is arranged on rail plate, rail plate is installed on supporting seat, the screw mandrel that on supporting seat, mounted motor drives, and screw mandrel is connected on sliding seat by feed screw nut; Supporting seat is provided with support cylinder, the piston rod of support cylinder is provided with the back-up block be supported on screw mandrel.This structure is supported on below screw mandrel by the back-up block supported on cylinder, prevents screw mandrel sagging, thus screw mandrel can be avoided to be out of shape, ensure higher precision.
In order to perfect further, back-up block is provided with the arc groove matched with screw mandrel external diameter.Better fit between such back-up block and screw mandrel, increase the contact area between back-up block and screw mandrel, support more stable.
Perfect further, support cylinder and have two at least and be distributed in the zone line of screw mandrel.The sagging region of screw mandrel mainly concentrates on centre, therefore will support cylinder and is arranged on the zone line of screw mandrel, and be intervally distributed with multiple stage.
Perfect further, the left and right sides supporting cylinder is separately installed with inductive switch.Because feed screw nut can bump against on back-up block in the process of movement, therefore respond to feed screw nut by inductive switch, feed screw nut near back-up block time, support cylinder back-up block is declined and allows feed screw nut pass through.This structure or employing extension position programming Control replace inductive switch, and this spline structure is more simple, operates safer.
The effect that the utility model is useful is: the utility model reasonable in design, be supported on below screw mandrel by the back-up block supported on cylinder, avoid sagging in the middle part of the screw mandrel of large span and cause screw mandrel can not the problem of High Rotation Speed, ensureing stationarity and the precision of working table movement speed and motion.

Description of reference numerals: workbench 1, pull bar 2, holder 2-1, sliding seat 3, rail plate 4, supporting seat 5, screw mandrel 6, feed screw nut 6-1, supports cylinder 7, back-up block 8, arc groove 8-1, inductive switch 9.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing: prevent the auxiliary support apparatus that screw mandrel is sagging in the present embodiment, comprise the workbench 1 for processing guide rail workpiece, workbench 1 is provided with the pull bar 2 of sliding guides workpiece, pull bar 2 is fixed on sliding seat 3 by holder 2-1, sliding seat 3 is arranged on rail plate 4, rail plate 4 is installed on supporting seat 5, the screw mandrel 6 that on supporting seat 5, mounted motor drives, and screw mandrel 6 is connected on sliding seat 3 by feed screw nut 6-1; Supporting seat 5 is provided with and supports cylinder 7, the piston rod of support cylinder 7 is provided with the back-up block 8 be supported on screw mandrel 6.Back-up block 8 is provided with the arc groove 8-1 matched with screw mandrel 6 external diameter.Support cylinder 7 have two at least and be distributed in the zone line of screw mandrel 6.The left and right sides supporting cylinder 7 is separately installed with inductive switch 9.
Although the utility model has illustrated by reference to preferred embodiment and has described, those skilled in the art should understand, and in the scope of claims, can do the various change in form and details.
