Abstract
The utility model relates to a long-stroke ball screw lifting system which comprises a plurality of position sensors arranged below a lead screw and a plurality of oil cylinder component, the oil cylinder components are arranged in the middle of the lead screw and are separated, and the position sensors controls the ascending and the descending of the corresponding oil cylinder components. After the technical scheme is adopted, before the lead screw stars to rotate, two oil cylinders ascend and lift the lead screws, and as the lead screw is lifted during rotation, rotary bouncing and deformation caused by drooping due to dead weight can be avoided basically, thus having good technical effects.
Description
Technical field
The design relates to a kind of long stroke ball-screw and lifts system, its be mainly used in solve long stroke ball-screw deadweight sagging with rotate at a high speed beat, vibration problem etc.
Background technology
Ball-screw has obtained using very widely at machine industry especially Digit Control Machine Tool industry at present.As lathe class feed motion mode, the common leading screw (ball) that comprises converts rotation into rectilinear motion, and the transmission of clearance elimination gear tooth bar converts motor into rectilinear motion, and the linear drives technology of conduct relative development at present etc.And because the lead screw transmission technology possesses clear superiority at aspects such as cost, precision, and obtaining increasing lifting aspect stroke, precision and the speed, therefore still take absolute predominance at the lathe drive part.
Than the lathe of farm labourer's part, present normally used leading screw (as more than 8 meters) is owing to receive restraining factors such as deadweight aspect for processing, in rotation, is easy to generate vibration and accuracy error etc., can't realize the processing that runs up.And along with leading screw length lengthening, this problem is obvious more.Mainly through reducing rotating speed as far as possible, perhaps use rack-and-pinion mode place of lead screw at present, realize that long stroke driving needs.
Summary of the invention
The design mainly analyzes the gravity sag problem that causes the leading screw vibration, produces through mechanism and lifts action, guarantees that leading screw receives balancing gravity under the external force effect, guarantees that leading screw can keep the stationarity of leading screw linearity and running under approximate state of weightlessness.
The technical scheme that the utility model technical solution problem is adopted is as described below:
A kind of long stroke ball-screw is lifted system; Comprise a plurality of position sensors and a plurality of cylinder component that are arranged on the leading screw below; And above-mentioned cylinder component is arranged on the middle part of leading screw 11 and separates, and said position sensor is controlled the rising and the decline of corresponding cylinder component.
Further, preferred construction is that said position sensor and cylinder component are set to two respectively; And; First bearing shell that said first cylinder component comprises first oil cylinder and is located at first oil cylinder top, and, be provided with the first adjustment screw between first oil cylinder and first bearing shell.
Further, preferred construction is, second bearing shell that said second cylinder component comprises second oil cylinder and is located at second oil cylinder top, and, be provided with the second adjustment screw between second oil cylinder and second bearing shell.
Further, preferred construction is that said primary importance inductor assembly connects and control the rise and the decline of first cylinder component; Said second place inductor assembly connects and controls the rise and the decline of second cylinder component.
Further, preferred construction is, also is connected with the first detection inductor that puts in place at said first cylinder component; Said second cylinder component also is connected with the second detection inductor that puts in place.
Further, preferred construction is to establish the auto-supply point at said first bearing shell and the second bearing shell place, and between leading screw and first bearing shell and second bearing shell, form oil film.
The utility model is after having taked technique scheme; Because before leading screw began to rotate, two oil cylinders lifted and lift leading screw, leading screw is lifted action owing to receiving in rotation; Basically can not cause rotation to be beated and distortion, have extraordinary technique effect because of deadweight is sagging.
Description of drawings
Below in conjunction with accompanying drawing the utility model is carried out detailed description, so that the above-mentioned advantage of the utility model is clearer and more definite.
Fig. 1 is that the long stroke ball-screw of the utility model is lifted the structural representation of system.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is carried out detailed description.
Like Fig. 1; Said long stroke ball-screw is lifted system, comprises a plurality of position sensors and a plurality of cylinder component that are arranged on the leading screw below, and; Above-mentioned cylinder component is arranged on the middle part of leading screw and separates, and said position sensor is controlled the rising and the decline of corresponding cylinder component.
And; Said position sensor and cylinder component are set to two respectively, and, first bearing shell 51 that said first cylinder component comprises first oil cylinder 21 and is located at first oil cylinder, 21 tops; And, be provided with the first adjustment screw 61 between first oil cylinder 21 and first bearing shell 51.
And said primary importance inductor assembly 31 connects and controls the rise and the decline of first cylinder component; Said second place inductor assembly 32 connects and controls the rise and the decline of second cylinder component.
And, also be connected with first at said first cylinder component and put in place and detect inductor 41; Said second cylinder component also is connected with second and puts in place and detect inductor 42.
Usually; Taked after the technique scheme, leading screw rotation nut is turned left from the right side and is moved through primary importance inductor 31, and this moment, feed screw nut 12 was avoided in 21 declines of first oil cylinder; After feed screw nut is through first oil cylinder, 21 positions; Trigger second place inductor 32, the first oil cylinders 21 and rise, continue to support leading screw.
Wherein in order to prevent that oil cylinder is declined by less than the position; Occur and the feed screw nut installation, be provided with first specially and put in place and detect inductor 41, when primary importance inductor 41 is connected back delay certain hour; The spindle motor autostop plays a protective role if inductor 2 can't accept signal.Simultaneously, also be provided with second and put in place and detect inductor 42, its effect is similar with it.
And, lift effectively in order to guarantee leading screw, and reduce the leading screw abrasion, on the one hand bush material is selected for use the low material of the relative leading screw of hardness, reduce leading screw is worn and torn; In addition, the bearing shell place establishes the auto-supply point, through between leading screw and bearing shell, forming oil film, reduces even avoids occurring wearing and tearing.
In addition, is connected through the adjustment nut between said bearing shell and the oil cylinder,, makes regular check on leading screw and beat, compensate the bearing shell abrasion condition when oil cylinder rising extreme position.
It should be noted that; Above-mentioned specific embodiment only is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of the utility model, are not to be used to limit the utility model.The protection domain of the utility model is limited claim and equivalent thereof.
