Abstract
The utility model relates to a machine tool saddle driving device with an anti-collision structure, comprising a lead screw which is driven by a direct current servo motor; the device is characterized in that one side which is close to a motor seat and one side which is close to a tail end seat of the lead screw are respectively provided with anti-collision pads; and a ball screw nut pair which is matched with the lead screw is arranged between the two anti-collision pads. The machine tool saddle driving device with the anti-collision structure can prevent the phenomenon of iron collision when a machine tool passes through strokes and improve the movement stability of the machine tool so as to improve the processing precision and service life of the machine tool.
Description
Technical field
The utility model relates to a kind of lathe saddle drive unit that has anti-collision structure, is applicable to the machining equipment field.
Background technology
The general no any crashproof measure of the saddle drive unit of existing machine tool three (X-axis, Y-axis and Z axles), when lathe is crossed stroke, ball guide screw nat will take place to be bumped mutually firmly with motor cabinet or tail end seat, noise is big, and can make motor cabinet and tail end seat loosening, and then cause the machining accuracy of lathe to descend, also can influence the life-span of lathe.
Summary of the invention
The purpose of this utility model is to provide a kind of lathe saddle drive unit that has anti-collision structure.
Of the present utility model being characterised in that: a kind of lathe saddle drive unit that has anti-collision structure, comprise the leading screw that drives by DC servo motor, described leading screw is respectively equipped with a bumper near a side of motor cabinet and a side of close tail end seat, and the ball guide screw nat that matches with leading screw is between two bumpers.
Advantage of the present utility model: can prevent to take place when lathe from crossing stroke iron and bump bumping firmly of iron, when the stroke collision took place lathe, noise was little, and motor cabinet and tail end seat are difficult for loosening, guarantee machine finish.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
The specific embodiment
With reference to shown in Figure 1, a kind of lathe saddle drive unit that has anti-collision structure, comprise the leading screw 2 that drives by DC servo motor 1, it is characterized in that: described leading screw 2 is respectively equipped with a bumper 5 near a side of motor cabinet 3 and a side of close tail end seat 4, and the ball guide screw nat 6 that matches with leading screw 2 is between two bumpers 5.
For the influence of the malalignment of eliminating motor shaft and leading screw 2, described DC servo motor 1 is connected with screw mandrel 2 front ends through shaft coupling 7.Described leading screw 2 two ends are all by bearing 8 supportings, and described bearing 8 is by nut 9 lockings, and described bumper 5 dormant bolts 10 are fixed on motor cabinet 3 or the tail end seat 4, and described motor cabinet 3 all is fixed on the bed piece with dormant bolt 10 with tail end seat 4.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
