Description
Technical field
The utility model belongs to a kind of anti-deformation mechanism, be applied to middle underloading and for long distance ball lead screw drive mechanism on use.
Background technique
The use of current ball screw module is comparatively general, and under the applicable situation of Long travel, often relevant workpiece precision problem becomes the bottleneck of ball wire rod mechanism; The ball screw quality of fit of being correlated with works when not high production and application, can cause that the working life of ball screw is short, operating accuracy is poor and motion time noise large; And then affect quality and the working environment of work production.
Model utility content
The utility model aims to provide a kind of ball leading screw driving fit tolerance absorbing mechanism, and object reaches in the relevant Workpiece Machining Accuracy difficulty that coordinates of the current ball wire rod mechanism of solution, and use with the life-span short, operating accuracy is poor, the problem that noise is large.
In order to solve the problem, the utility model solves its technical problem and have employed following technological scheme:
A kind of ball leading screw driving fit tolerance absorbing mechanism, comprise mountion plate, carrier board, slide rail, driving screw, driving screw nut, it is characterized in that: also comprise elastic steel sheet, the two ends of described mountion plate are provided with slide rail, motor and driving screw are installed in the intermediate groove of mountion plate, ball screw guiding nut is enclosed within driving screw, described ball screw guiding nut is fixedly connected with elastic steel sheet, the two ends of elastic steel sheet are installed on the bottom surface of carrier board by fixed block, the two ends of carrier board are fixedly connected with mountion plate by slide rail, and carrier board can slide along slide rail in mountion plate.
Preferably, described fixed block and elastic steel sheet are that slideway type is connected, and have two chutes in described fixed block, elastic steel sheet is fixedly connected with fixed block by mobile sliding pin, and elastic steel sheet can along slide in fixed block.
Preferably, be provided with Baltimore groove inside described fixed block, elastic steel sheet coordinates with Baltimore groove, is fixed on carrier board.
The utility model links by installing and using the good elastic steel sheet of toughness at the nut of ball screw with the carrier board place of link, steel disc carrier board is fixed together, can absorb when ball screw works not in place due to machining accuracy like this and trace that is that produce is deteriorated, the friction produced due to positional deviation between ball screw and transmission nut is reduced.Thus increase with the life-span, improve operating accuracy, reduce operating noise.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Figure 1-Figure 2, the utility model provides a kind of ball leading screw driving fit tolerance absorbing mechanism, comprise mountion plate 5, carrier board 7, slide rail 4, driving screw 3, driving screw nut 8, it is characterized in that: also comprise elastic steel sheet 6, the two ends of described mountion plate 5 are provided with slide rail 4, motor 2 and driving screw 3 are installed in the intermediate groove of mountion plate 5, ball screw guiding nut 8 is enclosed within driving screw 3, described ball screw guiding nut 8 is fixedly connected with elastic steel sheet 6, the two ends of elastic steel sheet 6 are installed on the bottom surface of carrier board 7 by fixed block 9, the two ends of carrier board 7 are fixedly connected with mountion plate 5 by slide rail 4, and carrier board 7 can slide along slide rail 4 in mountion plate 5.
Fig. 2 is an embodiment of the present utility model, and as shown in Figure 2, described elastic steel sheet is directly fixed on carrier board 7 with fixed block.
Fig. 3 and Fig. 4 is a preferred embodiment of the present utility model, as diagram, described fixed block 9 with elastic steel sheet 6 for slideway type is connected, two chutes are had in described fixed block 9, elastic steel sheet 6 is fixedly connected with fixed block 9 by mobile sliding pin 91, and elastic steel sheet 6 can along slide in fixed block.
As shown in Figure 5, in another embodiment of the present utility model, be provided with Baltimore groove inside described fixed block 9, elastic steel sheet 6 coordinates with Baltimore groove, is fixed on carrier board 7.
Working principle of the present utility model is: when elastic steel sheet 6 is direct and ball screw guiding nut 8 is connected and fixed, during revolution, ball screw guiding nut 8 will move forward and backward, when ball screw guiding nut 8 moves to deformation workpiece height direction had within 0.5mm, then elastic steel sheet 6 can be out of shape the error that absorbs on the relative position of workpiece, after using other embodiments, the relative mistake of absorption deformation can be made relatively to increase.
The utility model links by installing and using the good elastic steel sheet of toughness at the nut of ball screw with the carrier board place of link, steel disc carrier board is fixed together, can absorb when ball screw works not in place due to machining accuracy like this and trace that is that produce is deteriorated, the friction produced due to positional deviation between ball screw and transmission nut is reduced.Thus increase with the life-span, improve operating accuracy, reduce operating noise.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.
