Description
Technical field:
The present invention relates to machine science, a kind of multi-degree of freedom precision adjustment technique for non-allowance roll milling leaf blade is provided especially.
Background technology:
In the prior art, because the rolling basic theory and the restriction of technology level, people generally do not fully realize the blade and the importance of rolling six-freedom degree adjustment between the mould.In actual applications, do not carry out adjustment substantially.
In the prior art, the problem that blade occurs in the operation of rolling is not to solve by the method for adjusting usually, and is to use the method for restriking dies tool profile to solve.The characteristics of doing like this are: production efficiency is low, and the cycle that repairs a die is long, and needs the workman who enriches on-the-spot rolling experience and finish, and therefore becomes the technical bottleneck problem in the production.
But, in the blade operation of rolling owing to roller mill, rolling woollen reasons such as state with frock and before rolling, the blade that rolls out tends to occur the deviation between all and the ideal blade, and these deviations mainly comprise: blade is to the leaf basin or carry on the back that offsetting appears in a lateral bending song, tenon and blade, cross section torsional angle inconsistent (cross and turn round and the torsional angle deficiency), blade be to problems such as edge one lateral bending song, seaming malpositions.
It is very normal these situations occurring, algorithm design rolling model face is to carry out under the perfect condition of hypothesis because use tricks, and the operation of rolling is with perfect condition certain deviation to be arranged, in order to eliminate these deviations, will carry out the adjustment of the six-freedom degree between blade and the rolling mould, these adjustment technologies are to realize by the adjustment function of improving milling train and the structure of improving the blade chuck, and grope method of adjustment and rule in the operation of rolling.
The following problem of normal appearance in producing at the scene: blade is to leaf basin or blade back one lateral bending song, offsetting appears in tenon and blade, the torsional angle of rolling cross section and design section is inconsistent: for example cross and turn round and the torsional angle deficiency, blade is to air inlet or exhaust limit one lateral bending song, problems such as the malposition of seaming.
We think that by analysis the main cause that produces these problems is the rule owing to rolling mould and the relative position incompatibility metal flow of blade in the operation of rolling, and perhaps the rolling mould exists shortcoming with the design of rolling preceding woolen cloth.
People expect to obtain a kind of multi-degree of freedom precision adjustment technique for non-allowance roll milling leaf blade that can solve a prior art difficult problem.
Summary of the invention:
The multi-degree of freedom precision adjustment technique for non-allowance roll milling leaf blade that the purpose of this invention is to provide a kind of novelty.
The present invention has made the application and the adaptive innovation transformation of innovation formula according to existing rolling equipment; Its pairing milling train traditional structure is described as follows referring now to Figure 17 with relevant basic functional principle:
Milling train is specially framework swing type roller mill.The characteristics of roller mill are provided with swing each other, and the roll 812 of rigid frame is housed, the blade forming instrument is housed on the roll 812 rolls mould, for roll-in fricton-tight, roll 812 each other and use gears engaged between the rigid frame, in order to guarantee that contact wire is in a plane between roll 812 and the framework, be provided with the support that vertically moves, roll pins having utilizes the guide rail on the sidewall to keep on a vertical plane by rolling bearing within it.Move the transmission that support has been realized roll 812 by primary load bearing hydraulic actuator 805.
The little hydraulic actuator 804 of auxiliary moving also is housed in the secondary frame 803, and fixedly the dressing double-layered quilt is processed the chuck that blade is used on its push rod.In addition, little hydraulic actuator 804 can be with push rod and blade by the copying apparatus transmission when rolling, and what guarantee that the blade blade is necessary reverses.
The framework oscillating rolling mill comprises following critical piece:
The lathe bed 809 that has the Rectangular Rigid framework has the mainframe 808 of roll 812 and gear 816, has the secondary frame 803 of little hydraulic actuator 804 and serration bar 802, primary load bearing hydraulic actuator 805, pumping plant, electric system and the operating desk of mobile support.
The lathe bed parts comprise inner chamber, base 801 as the oil pump fuel tank, the framework lathe bed 809 that has the rectangle of rectangular window, platform 810 and lower platform 815 are housed down thereon, with load tooth bar 811, left tooth bar 813, right tooth bar 817, and primary load bearing hydraulic actuator 805 usefulness load platforms 806 are installed, it and framework lathe bed 809 and hanging stick 807 link with the raising rigidity.
The mainframe 808 that moves along horizontal line in framework lathe bed 809 windows has main hydraulic actuator 805 push rod bearings and roll 812, and the end between them is by gear 816 connections and be used for carrying corresponding with it carrying rolling mould 814.Support is equipped with little hydraulic actuator 804, secondary frame 803 and guide.802 transmissions of secondary frame 803 usefulness serration bars are connected with roll 812.
Primary load bearing hydraulic actuator 805 is fixed on the load platform 806 and with push rod and is fixed on the mainframe 808.Little hydraulic actuator 804 is that bipartite special-purpose oil pump provides power.
In order to guarantee the semi-automatic work circulation of milling train, on hanging stick 807, be fixed with 5 travel switches, and corresponding cam is installed on mainframe 808, they send down column signal: the home position of mainframe 808; Back boundary position and emergent anterior position; Mould " bite " blade before moment little pressurized strut push rod withdraw from signals such as blade.
Roll 812 rolls along load platform 806, platform 810 and lower platform 815 in the working cycles process, and keeps pre-interference 0.4～0.5mm to each other.Floating bearing on roll 812 axle journals keeps its axis in a vertical plane and by the tractive force of mainframe 808 to axle transmission primary load bearing hydraulic actuator 805.Rigid motion connection between roll 812 is guaranteed that by 4 gears 816 gear 816 meshes with left tooth bar 813 with load.The pitch diameter of gear 816 and roll 812 equal diameters, therefore, they roll fricton-tight along platform 810, lower platform 815.

In the research process of a kind of multi-degree of freedom precision adjustment technique for non-allowance roll milling leaf blade of the present invention, for the convenience that studies a question, at first we set a coordinate system as shown in Figure 1 on blade: the blade length direction is set at the Z direction, blade basin, back of the body direction setting are the Y direction, blade inlet and outlet direction setting is a directions X, will occur in the operation of rolling along the mobile of X, Y, Z-direction with around the adjustment aspect the rotation of X, Y, Z axle.
A kind of multi-degree of freedom precision adjustment technique for non-allowance roll milling leaf blade of the present invention, it is characterized in that: utilize one of following two kinds of methods or its combination to realize the adjustment of 6 frees degree of blade in the operation of rolling: one, utilize the guiding mechanism of milling train itself, the adjustment function of development and application milling train; Its two, use custom-designed be used for remedying roller mill the vanes fixed anchor clamps of the irrealizable free degree realize the adjustment of blade in the operation of rolling free degree.
In described multi-degree of freedom precision adjustment technique for non-allowance roll milling leaf blade, utilize the guiding mechanism of milling train itself, the adjustment function of development and application milling train realizes that the adjustment process of the free degree of blade in the operation of rolling comprises one of following several concrete adjustment schemes or its combination:
1, the X-direction adjustment of moving: in order to solve blade tenon position and the problem of blade to skew, leaf basin and the offsetting of blade back profile of intake and exhaust edge direction; Concrete grammar is respectively: adjust two rolls up and down simultaneously or adjust the horizontal level of any one roll;
2, the Z-direction adjustment of moving: be used to guarantee that the seaming physical location overlaps with theoretical position so that obtain qualified blade; Concrete grammar is respectively: adjust the position of blade Z-direction on milling train by control Z to adjusting nut 201;
3, around the adjustment of Z axle rotation: be used to control blade integral body with respect to the deflection of tenon center or/and blade tip with respect to tenon center amount of deflection; Because in feeler mechanism, guide roller 302 rolls in the gathering sill of feeler mechanism, gathering sill is by the angular position of guide roller 302 control small piston rods; We adjust around the adjustment of Z axle rotation by the feeler mechanism realization blade to movable machine frame top as shown in Figure 7; Concrete method of adjustment is respectively:
For the whole deflection of blade: the direction of rotation that need press blade is come whole parallel mobile feeler mechanism, the deviation angle of mobile distance by measuring blade, determines that the roller center is to valve piston centre distance and calculate to determine;
Deflection problem for blade tip: need come the position of closed slide in the mobile feeler mechanism by the direction of rotation of blade, mobile distance by measure blade tip with respect to the deviation angle of blade root, determine that the roller center is to valve piston centre distance and calculate to determine;
When above-mentioned two kinds of adjustment need be carried out simultaneously, adjust the whole deflection of blade earlier, the deflection of blade tip is adjusted in the back.
In the described multi-degree of freedom precision adjustment technique for non-allowance roll milling leaf blade, utilize the guiding mechanism of milling train itself, the adjustment function of development and application milling train realizes that the preferred content in the adjustment process of the free degree of blade in the operation of rolling is as follows: we can carry out following transformation to original milling train according to the actual needs: the structure perpendicular to X-direction that is used for the adjustment that X-direction moves on the milling train is replaced by the nut that has scale: roll is adjusted nut 102; On roll adjustment nut 102, scale is arranged, lattice of every rotation, roll 103 is with regard to the certain straight-line displacement of translation.
The guiding mechanism that utilizes milling train itself that relates in the foregoing, the adjustment function of development and application milling train realize that the further preferred particular content of the three major types adjustment process of the free degree of blade in the operation of rolling is following one of several or its combination:
1, the X-direction adjustment of moving
The problem that the adjustment that X-direction moves mainly solves: blade tenon position and blade are to the problem of skew, leaf basin and the offsetting of blade back profile of intake and exhaust edge direction; Main forms at blade is the inlet and outlet one side printing opacity of leaf basin or leaf back; As shown in Figure 2.
The detailed process of the adjustment that X-direction moves is: will determine that at first roll wants the distance of move left and right; Unclamp the roll of moving direction indication one side then and adjust nut 102, the roll that has scale of precession opposite side is adjusted nut 102 then, roll is adjusted the drift 103 that nut 102 drives lathe beds 101 both sides and is moved forward and backward, drift 103 move forward and backward the move left and right that has driven whole roll 103; According to shown in Fig. 3 for moving up and down;
On roll adjustment nut 102, scale is arranged, lattice of every rotation, roll is with regard to the certain straight-line displacement of translation; Our occurrence can be 0.01mm;
The horizontal adjusting amount of whole roll is about 2mm.Can not use this function, roller mill left and right adjusting mechanism such as Fig. 3 because mould structure is unreasonable in the production;
Blade tenon position and blade to the reason of the skew generation of intake and exhaust edge direction are: blade center and rolling mould center level occurs and offset;
The reason that leaf basin and the offsetting of blade back profile produce is: the top and bottom rolls center produces and offsets.---adjust two rolls up and down in the time of at this time will seeking common ground usually or adjust the horizontal level of any one roll.This adjustment function has possessed in the milling train design process, and what can not adjust in still on-the-spot the use mainly is rolling Mould design unreasonable structure, can not realize adjusting;
Because the precision prescribed of horizontal adjusting is than higher, the function of the horizontal adjusting of existing milling train exists adjustment amount can not digitlization, and the operator will measure after adjusting, and adjusts repeatedly then just can reach the expection requirement.
So be necessary the traditional structure of milling train is simply transformed, to change the roll that has scale and adjust nut 102, the size of adjustment amount is adjusted nut 102 by roll and controlled, and is simple and convenient.---convert straight-line displacement to circular motion, certain circumference angle value correspondence certain straight line and is adjusted displacement.
The process of the main operation of the adjustment that X-direction moves can be: will determine that at first roll wants the distance of move left and right; Unclamp the roll of moving direction indication one side then and adjust nut, the nut that has scale of precession opposite side then, the wedge that nut drives both sides moves forward and backward the mobile move left and right that drives whole roll of the front and back of wedge; According to shown in Fig. 3 for moving up and down;
On roll adjustment nut 102, scale is arranged, lattice of every rotation, roll is with regard to the certain straight-line displacement of translation; The horizontal adjusting amount of whole roll is about 2mm.Can not use this function because mould structure is unreasonable in the production, the roller mill left and right adjusting mechanism as shown in Figure 3.
2, the Z-direction adjustment of moving
Set blade seaming position in rolling mould design process, the original position of mould design section is just rolled in the position of blade seaming;
Specification requirement: in the operation of rolling, have only the seaming physical location to overlap, just may obtain qualified blade with theoretical position;
The problem that exists: first point, in the operation of rolling, before crossing, the seaming position wounds easily or the tenon that bites, and then blade profile is incorrect later in the seaming position; Second point owing to the error in length of blade chuck manufacturing, the reasons such as rigging error of rolling molded angular error of making and milling train, seaming often occurs and crosses phenomenon preceding or later;---therefore will adjust the position of blade Z-direction on milling train.The structure of milling train is shown in figure four.
The adjustment process that Z-direction moves is: rotation Z carries out the Z-direction adjustment to adjusting nut 201; The nut front end has the groove of 8 equal portions usually, hooks groove with hook spanner and rotates nut, and the pitch of nut is 2mm.---we judge adjustment amount by calculating the position of groove rotation.
Because the seaming position accuracy demand is not very accurate, add front end measurement clip position by judgement, obtaining suitable dimension is eaily.
3, the adjustment of rotating around the Z axle
Existing problem: in the blade operation of rolling, occur tenon and blade often and theoretical profile has deflection.This deflection generally is divided into two kinds of situations, a kind of situation be blade integral body with respect to the deflection of tenon center, another kind of situation is blade root correct position and blade tip deflection; As Fig. 5, shown in Figure 6.
Mode for these two kinds of deflections, as shown in Figure 7, mainly be on the feeler mechanism of milling train adjustment, the feeler mechanism on movable machine frame top to be adjusted: in feeler mechanism, as shown in Figure 8, guide roller 302 rolls in the gathering sill of feeler mechanism, and gathering sill is by the angular position of guide roller 302 control small piston rods;
The concrete adjustment process of adjusting around the rotation of Z axle can be:
For the whole deflection of blade: the direction of rotation that need press blade is come whole parallel mobile feeler mechanism, the deviation angle of mobile distance by measuring blade, determines that the roller center is to valve piston centre distance and calculate to determine.
Deflection problem for blade tip: need come the position of closed slide in the mobile feeler mechanism by the direction of rotation of blade, mobile distance by measure blade tip with respect to the deviation angle of blade root, determine that the roller center is to valve piston centre distance and calculate to determine.
When above-mentioned two kinds of adjustment need be carried out simultaneously, require to adjust earlier the whole deflection of blade usually, the deflection of blade tip is adjusted in the back.
Sum up above-mentioned three major types adjustment process, they all are to utilize the function of milling train that the free degree of as-rolled condition lower blade is adjusted.
The invention allows for and realize that blade does not have the second largest class scheme that surplus rolling multiple degrees of freedom is adjusted:
The vanes fixed anchor clamps are undergone technological transformation, do not realize to realize free degree adjustment originally milling train so that have in the surplus rolling process at blade.Concrete operating process can be adopted one of following three kinds of concrete adjustment schemes or its combination:
In the described multi-degree of freedom precision adjustment technique for non-allowance roll milling leaf blade, use custom-designed be used for remedying roller mill the vanes fixed anchor clamps of the irrealizable free degree realize that blade comprises one of following several concrete adjustment schemes or its combination in the adjustment process of the operation of rolling blade free degree:
The adjustment that one, Y direction move: in order to solve the problem of blade, on equipment, can not adjust, have only by the blade chuck and adjust tenon Y direction position owing to roll the mould center with respect to mind-set leaf basin in the tenon or the skew of back of the body direction; Concrete method of adjustment is one of following two kinds or its combination:
One, on chuck, use the eccentric key 401 that can upper and lowerly adjust to adjust the position of Y direction, concrete form is as shown in figure 10; Two, four eccentric wheels of adjustment billy gate bottom are realized the chuck lifting;
Two, the adjustment of rotating around Y-axis: thus be used to solve because the edge thickness of blade woolen cloth is inharmonious or the blade center makes blade the problem of lateral bending occur with rolling direction formation drift angle; Concrete method of adjustment is: blade is rotated the drift angle that the thickness that remedies the inlet and outlet limit is inharmonious or eliminate blade center and rolling direction around the Z axle;
Three, the adjustment of rotating: be used to control blade with respect to the reversing of tenon, the inconsistent situation of rotational line speed of avoiding the chuck of clamping blade to tilt up or down or roll mould up and down around X-axis; Concrete method of adjustment is: use the fixed angle piece: have the little secter pat of certain corresponding central angle to adjust around X-axis and rotate degree;
Described in the foregoing of the present invention the vanes fixed anchor clamps are undergone technological transformation, so that have in the surplus rolling process preferred content that realizes can not realizing originally concrete three class methods that adopt in the process that the free degree adjusts are not: specifically adopt one of following three kinds of concrete adjustment schemes or its combination to carry out three following class adjustment milling train at blade:
The adjustment that one, Y direction move:
Problem: in the blade operation of rolling, often occur blade with respect to tenon in mind-set leaf basin or back of the body direction skew; As shown in Figure 8.
The reason that produces is: the center of the center of blade chuck and rolling mould can not be adjusted on equipment owing to roll the mould center not at same horizontal level, has only by the blade chuck and adjusts tenon Y direction position.
One of corresponding method of adjustment: use eccentric key to adjust the position of Y direction on chuck, concrete form is shown in figure nine.In order to obtain a series of adjusted value, the offset of eccentric key is generally 0.1mm at interval and gets final product respectively from 0.1～1mm; The foundation that the offset of eccentric key is chosen at interval is: the profile that the blade design drawing requires generally at 0.12～0.2mm, selects for use 0.1mm as the adjustment of eccentric key 401 at interval with respect to the position degree at center, can satisfy the demand; Eccentric key can upper and lowerly be adjusted, and adjusts simple and conveniently, and precision is also than being easier to assurance.
Two of method of adjustment: four eccentric wheels adjusting the billy gate bottom, realize the chuck lifting, because four eccentric wheels roll on guide rail, good gap is arranged, be both four eccentric wheels and also control the inclination of dolly, this method is adjusted cumbersome, and will beat the depth of parallelism of oil cylinder of table look-up dolly and the changing value of rising or decline, and this method is compared without any advantage comparable with eccentric key.
Two, the adjustment of rotating around Y-axis:
Problem: in the operation of rolling of blade,, make blade lateral bending occur: be commonly called as and be " sabre shape " because the edge thickness of blade woolen cloth is inharmonious or blade center and rolling direction formation drift angle; As shown in figure 11.Solution: this situation will be rotated the drift angle that the thickness that remedies the inlet and outlet limit is inharmonious or eliminate blade center and rolling direction around the Z axle with blade.
In order to realize this adjustment function, clip designs is become the composition surface of two circular arcs, two arc surfaces cooperate to be made, and stained area is not less than 80%, and the size of R is to determine that by the position of seaming seaming is the center of circle of circular arc.Two screws connect together two circular arcs with spherical washer, and concrete form as shown in figure 12.
Be in course of adjustment, at first to measure the angle and direction of blade deflection, make chuck deflection by adjusting the both sides screw, use the chuck standard component to check the angle of required deflection, beat table look-up small oil tank stretch out and the state of withdraw under, the variable quantity of indicator, the data of horizontal displacement on the acquisition collapsing length, collapsing length by small oil tank calculates deflection angle, can also realize fine setting by screw simultaneously.
Three, the adjustment of rotating around X-axis:
Occurring the situation that blade reverses with respect to tenon after blade is rolling, is blade surplus deflection leaf basin or blade back in the sign of measuring process; As shown in figure 13;
Reason: this situation be inconsistent the causing of rotational line speed that the chuck by the clamping blade tilts up or down or rolls mould up and down.We will analyze the reason of deflection of blade and the direction of deflection in this case, adjust the rotation of blade around X-axis.
We have designed the fixed angle piece and adjust for this adjustment: angle block gauge has a series of angle value, get usually per 10 ' be divided into one grade, maximum adjustment angle is 1 °.
Every milling train only need be joined once eccentric key of cover and angle block gauge and can be used.The structure full figure of rolling vane chuck as shown in figure 16.
In terms of existing technologies, the present invention has realized that really blade does not have the adjustment of surplus rolling six degree of freedom.The blank that it has filled up a key technology has predictable huge economy, society and national defence and is worth.

On roll adjustment nut 102, scale is arranged, lattice of every rotation, roll is with regard to the certain straight-line displacement of translation; Our occurrence can be 0.01mm;
The horizontal adjusting amount of whole roll is about 2mm.Can not use this function, roller mill left and right adjusting mechanism such as Fig. 3 because mould structure is unreasonable in the production;
Blade tenon position and blade to the reason of the skew generation of intake and exhaust edge direction are: blade center and rolling mould center level occurs and offset;

So be necessary the traditional structure of milling train is simply transformed, to change the roll that has scale and adjust nut 102, the size of adjustment amount is adjusted nut 102 by roll and controlled, and is simple and convenient.---convert straight-line displacement to circular motion, certain circumference angle value correspondence certain straight line and is adjusted displacement.
The process of the main operation of the adjustment that X-direction moves can be: will determine that at first roll wants the distance of move left and right; Unclamp the roll of moving direction indication one side then and adjust nut, the nut that has scale of precession opposite side then, the wedge that nut drives both sides moves forward and backward the mobile move left and right that drives whole roll of the front and back of wedge; According to shown in Fig. 3 for moving up and down;
On roll adjustment nut 102, scale is arranged, lattice of every rotation, roll is with regard to the certain straight-line displacement of translation; The horizontal adjusting amount of whole roll is about 2mm.Can not use this function because mould structure is unreasonable in the production, the roller mill left and right adjusting mechanism as shown in Figure 3.
2, the Z-direction adjustment of moving: be used to guarantee that the seaming physical location overlaps with theoretical position so that obtain qualified blade; Concrete grammar is respectively: adjust the position of blade Z-direction on milling train by control Z to adjusting nut 201;
Particularly, set blade seaming position in rolling mould design process, the original position of mould design section is just rolled in the position of blade seaming;
Specification requirement: in the operation of rolling, have only the seaming physical location to overlap, just may obtain qualified blade with theoretical position;
The problem that exists: first point, in the operation of rolling, before crossing, the seaming position wounds easily or the tenon that bites, and then blade profile is incorrect later in the seaming position; Second point owing to the error in length of blade chuck manufacturing, the reasons such as rigging error of rolling molded angular error of making and milling train, seaming often occurs and crosses phenomenon preceding or later;---therefore will adjust the position of blade Z-direction on milling train.The structure of milling train is shown in figure four.
The adjustment process that Z-direction moves is: rotation Z carries out the Z-direction adjustment to adjusting nut 201; The nut front end has the groove of 8 equal portions usually, hooks groove with hook spanner and rotates nut, and the pitch of nut is 2mm.
---we judge adjustment amount by calculating the position of groove rotation.
Because the seaming position accuracy demand is not very accurate, add front end measurement clip position by judgement, obtaining suitable dimension is eaily.
3, around the adjustment of Z axle rotation: be used to control blade integral body with respect to the deflection of tenon center or/and blade tip with respect to tenon center amount of deflection; Because in feeler mechanism, guide roller 302 rolls in the gathering sill of feeler mechanism, gathering sill is by the angular position of guide roller 302 control small piston rods; We adjust around the adjustment of Z axle rotation by the feeler mechanism realization blade to movable machine frame top as shown in Figure 7;
In the described multi-degree of freedom precision adjustment technique for non-allowance roll milling leaf blade, utilize the guiding mechanism of milling train itself, the adjustment function of development and application milling train realizes that the preferred content in the adjustment process of the free degree of blade in the operation of rolling is as follows: we can carry out following transformation to original milling train according to the actual needs: the structure perpendicular to X-direction that is used for the adjustment that X-direction moves on the milling train is replaced by the nut that has scale: roll is adjusted nut 102; On roll adjustment nut 102, scale is arranged, lattice of every rotation, roll 103 is with regard to the certain straight-line displacement of translation.
Particularly, around the existing problem in adjustment aspect of Z axle rotation: in the blade operation of rolling, occur tenon and blade often and theoretical profile has deflection.This deflection generally is divided into two kinds of situations, a kind of situation be blade integral body with respect to the deflection of tenon center, another kind of situation is blade root correct position and blade tip deflection; As Fig. 5, shown in Figure 6.
For the mode of these two kinds of deflections, as shown in Figure 7, mainly be on the feeler mechanism of milling train adjustment, the feeler mechanism on movable machine frame top to be adjusted:
In feeler mechanism, as shown in Figure 8, guide roller 302 rolls in the gathering sill of feeler mechanism, and gathering sill is by the angular position of guide roller 302 control small piston rods;
The concrete adjustment process of adjusting around Z axle rotation can be: for the whole deflection of blade: the direction of rotation that need press blade is come whole parallel mobile feeler mechanism, the deviation angle of mobile distance by measuring blade, determines that the roller center is to valve piston centre distance and calculate to determine.Deflection problem for blade tip: need come the position of closed slide in the mobile feeler mechanism by the direction of rotation of blade, mobile distance by the distance that moves by measure blade tip with respect to the deviation angle of blade root, determine that the roller center is to valve piston centre distance and calculate to determine.When above-mentioned two kinds of adjustment need be carried out simultaneously, require to adjust earlier the whole deflection of blade usually, the deflection of blade tip is adjusted in the back.
Above-mentioned three major types adjustment process, they all are to utilize the function of milling train that the free degree of as-rolled condition lower blade is adjusted.
Present embodiment has proposed also to realize that blade does not have the second largest class scheme that surplus rolling multiple degrees of freedom is adjusted:
The vanes fixed anchor clamps are undergone technological transformation, do not realize to realize free degree adjustment originally milling train so that have in the surplus rolling process at blade.Concrete operating process can be adopted one of following three kinds of concrete adjustment schemes or its combination:
In the described multi-degree of freedom precision adjustment technique for non-allowance roll milling leaf blade, use custom-designed be used for remedying roller mill the vanes fixed anchor clamps of the irrealizable free degree realize that blade comprises one of following several concrete adjustment schemes or its combination in the adjustment process of the operation of rolling blade free degree:
The adjustment that one, Y direction move: in order to solve the problem of blade, on equipment, can not adjust, have only by the blade chuck and adjust tenon Y direction position owing to roll the mould center with respect to mind-set leaf basin in the tenon or the skew of back of the body direction; Concrete method of adjustment is one of following two kinds or its combination: one, and on chuck, use the eccentric key 401 that can upper and lowerly adjust to adjust the position of Y direction, concrete form is as shown in figure 10; Two, four eccentric wheels of adjustment billy gate bottom are realized the chuck lifting;
Particularly, the existing subject matter in adjustment aspect that moves of Y direction is: in the blade operation of rolling, often occur blade with respect to tenon in mind-set leaf basin or the skew of back of the body direction; As shown in Figure 8.The reason that produces is: the center of the center of blade chuck and rolling mould can not be adjusted on equipment owing to roll the mould center not at same horizontal level, has only by the blade chuck and adjusts tenon Y direction position.
One of corresponding concrete method of adjustment: use eccentric key to adjust the position of Y direction on chuck, concrete form is shown in figure nine.In order to obtain a series of adjusted value, the offset of eccentric key is generally 0.1mm at interval and gets final product respectively from 0.1～1mm; The foundation that the offset of eccentric key is chosen at interval is: the profile that the blade design drawing requires generally at 0.12～0.2mm, selects for use 0.1mm as the adjustment of eccentric key 401 at interval with respect to the position degree at center, can satisfy the demand; Eccentric key can upper and lowerly be adjusted, and adjusts simple and conveniently, and precision is also than being easier to assurance.
Two of method of adjustment: four eccentric wheels adjusting the billy gate bottom, realize the chuck lifting, because four eccentric wheels roll on guide rail, good gap is arranged, be both four eccentric wheels and also control the inclination of dolly, this method is adjusted cumbersome, and will beat the depth of parallelism of oil cylinder of table look-up dolly and the changing value of rising or decline, and this method is compared without any advantage comparable with eccentric key.
Two, the adjustment of rotating around Y-axis: thus be used to solve because the edge thickness of blade woolen cloth is inharmonious or the blade center makes blade the problem of lateral bending occur with rolling direction formation drift angle; Concrete method of adjustment is: blade is rotated the drift angle that the thickness that remedies the inlet and outlet limit is inharmonious or eliminate blade center and rolling direction around the Z axle;
Around the existing problem in adjustment aspect that Y-axis is rotated: in the operation of rolling at blade,, make blade lateral bending occur: be commonly called as and be " sabre shape " because the edge thickness of blade woolen cloth is inharmonious or blade center and rolling direction formation drift angle; As shown in figure 11.
Solution: this situation will be rotated the drift angle that the thickness that remedies the inlet and outlet limit is inharmonious or eliminate blade center and rolling direction around the Z axle with blade.
In order to realize this adjustment function, clip designs is become the composition surface of two circular arcs, two arc surfaces cooperate to be made, and stained area is not less than 80%, and the size of R is to determine that by the position of seaming seaming is the center of circle of circular arc.Two screws connect together two circular arcs with spherical washer, and concrete form as shown in figure 12.
Be in course of adjustment, at first to measure the angle and direction of blade deflection, make chuck deflection by adjusting the both sides screw, use the chuck standard component to check the angle of required deflection, beat table look-up small oil tank stretch out and the state of withdraw under, the variable quantity of indicator, the data of horizontal displacement on the acquisition collapsing length, collapsing length by small oil tank calculates deflection angle, can also realize fine setting by screw simultaneously.
Three, the adjustment of rotating: be used to control blade with respect to the reversing of tenon, the inconsistent situation of rotational line speed of avoiding the chuck of clamping blade to tilt up or down or roll mould up and down around X-axis; Concrete method of adjustment is: use the fixed angle piece: have the little secter pat of certain corresponding central angle to adjust around X-axis and rotate degree;
Particularly, the situation that blade reverses with respect to tenon occurring after blade is rolling, is blade surplus deflection leaf basin or blade back in the sign of measuring process; As shown in figure 13;
Reason: this situation be inconsistent the causing of rotational line speed that the chuck by the clamping blade tilts up or down or rolls mould up and down.We will analyze the reason of deflection of blade and the direction of deflection in this case, adjust the rotation of blade around X-axis.
We have designed the fixed angle piece and adjust for this adjustment: angle block gauge has a series of angle value, get usually per 10 ' be divided into one grade, maximum adjustment angle is 1 °.
Every milling train only need be joined once eccentric key of cover and angle block gauge and can be used.The structure full figure of rolling vane chuck as shown in figure 16.
