According to the multi-level adjustable lead screw device, multi-level position adjusting can be achieved on the same center line, the working efficiency is improved, optimal integration of a multi-level adjusting mechanism is achieved, the guiding links are reduced, and the multi-level adjustable lead screw device has the advantages of being convenient to operate and compact in structure.
Description
Technical field
The present invention relates to multistage situation monitoring, particularly a kind of Multi-stage adjustable lead screw device.
Background technique
It is straight line motion that feed screw nut (being commonly called as feed screw nut) mechanism is used to convert rotational motion, or is the executive component of rotary motion by transform linear motion, can be used for the occasions such as position adjustment, heavy lift, pretension location.
More common screw-nut body is all single-stage driving, realizes nut respectively or leading screw carries out straight line motion according to the helical pitch of corresponding specification by rotating threaded shaft or rotating nut.If need to carry out position adjustment to multiple parts, the actuator of respective numbers will be adopted to regulate and control.This creates the terminal following intrinsic defect: (1) can only realize independent adjustment, can not coordinated signals be realized, reduce working efficiency; (2) design of multilayer actuator increases complete machine weight, increases the friction effects of adjustment process, reduces the synchronism of data feedback.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of Multi-stage adjustable lead screw device, multistage situation monitoring can be realized on same center line, improve working efficiency, the optimization achieving Multi-regulation mechanism is integrated, decrease guiding link, have easy to operate, the advantage of compact structure.
To achieve these goals, the technical solution used in the present invention is:
A kind of Multi-stage adjustable lead screw device, comprise one end with leading screw 2 in interior leading screw flange 1, outer leading screw 4 is set with outside interior leading screw 2, outer leading screw 4 is provided with outer leading screw forward flange 3 near one end of interior leading screw flange 1, the other end of outer leading screw 4 is provided with outer leading screw rear flange 6, outer leading screw 4 is provided with front regulation box 5, interior leading screw 2 is provided with middle regulation box 7 and rear regulation box 8.
Described middle regulation box 7 is pressed close to outer leading screw rear flange 6 and is installed, and described rear regulation box 8 is near the other end of interior leading screw 2.
Described rear regulation box 8 is provided with dust-proof cover 9.
Described front regulation box 5 is provided with front connecting plate 10, middle regulation box 7 is provided with middle connecting plate 11, rear regulation box 8 is provided with rear connecting base 12.
Described front regulation box 5, middle regulation box 7 and rear regulation box 8 be built-in nut all, and front regulation box 5 forms screw-nut structure with outer leading screw 4, and middle regulation box 7 and rear regulation box 8 form screw-nut structure with interior leading screw 2 respectively.
Compared with prior art, the present invention has selected set type screw-nut body, and is provided with multiple regulation box, therefore not only makes global design compacter, and achieves and adjust the grading type position of each connected element.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the side schematic view of embodiment of the present invention.
Embodiment
Embodiments of the present invention are described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of Multi-stage adjustable lead screw device, comprise one end with leading screw 2 in interior leading screw flange 1, outer leading screw 4 is set with outside interior leading screw 2, outer leading screw 4 is provided with outer leading screw forward flange 3 near one end of interior leading screw flange 1, the other end of outer leading screw 4 is provided with outer leading screw rear flange 6, and outer leading screw 4 is provided with front regulation box 5, and interior leading screw 2 is provided with middle regulation box 7 and rear regulation box 8.Middle regulation box 7 is pressed close to outer leading screw rear flange 6 and is installed, and rear regulation box 8 is near the other end of interior leading screw 2.Front regulation box 5, middle regulation box 7 and rear regulation box 8 be built-in nut all, and in front regulation box 5, nut is screwed on outer leading screw 4 and forms screw-nut structure, and middle regulation box 7 and rear regulation box 8 are screwed on interior leading screw 2 by nut respectively and form screw-nut structure.Front regulation box 5 is provided with front connecting plate 10, middle regulation box 7 is provided with middle connecting plate 11, rear regulation box 8 is provided with rear connecting base 12.
The working principle of this device is:
Three the parts sub-headends carrying out regulating and controlling will be needed, middle, tail end, respectively with interior leading screw flange 1, outer leading screw forward flange 3, the front-end face of front connecting plate 10 connects, after adjustment, regulation box 8 seesawing on interior leading screw 2 can realize synchronously carrying out position adjustment to three parts, in the middle of adjustment, regulation box 7 seesawing on interior leading screw 2 can realize between synchronous centering, tail end two parts carry out position adjustment, regulation box 5 seesawing and can carry out position adjustment separately to intermediate member outside on leading screw 4 before adjustment, because screw-nut body has auto-lock function, therefore each parts can automatic locking after adjusting to the right place.Rear regulation box 8 is provided with dust-proof cover 9, necessary protection can be carried out to rear regulation box 8.
In the present invention, train of reduction gears and auxiliary leading screw and nut can be added in front regulation box 5, middle regulation box 7 and rear regulation box 8, each regulation box stretches out the rotatingshaft of a connecting handle 13 respectively, is adjusted corresponding leading screw by handle with sleeve 13, makes operation easier.
