Description
Technical field
The present invention relates to a kind of grinder for being used to carry out workpiece mechanical lapping.
Background technology
Grinder is fully disclosed by prior art.Most of grinders are the bases, at least that there is position to fix herein
The grinder of one slide plate that can be moved and the linear steering mechanism constructed between the base and the slide plate.The cunning
Plate can be moved by means of channeling direction of the linear steering mechanism along the linear steering mechanism.In order to be processed to having
Workpiece is ground, and the grinder has milling tool unit.The milling tool unit is fixed on the slide plate or institute
State on base.By the movement of the slide plate or the base, the milling tool unit can be directed into be processed
Workpiece on or will there is workpiece to be processed to direct on the milling tool unit.The accuracy of grinding is in itself for grinding
Diversified factor is depended on for machine.One of these factor to affect are the guidance accuracies of the linear steering mechanism.
If the guidance accuracy very little of the linear steering mechanism, that can is it is contemplated that grinding result equally has the precision of very little
Quality.
In addition, the known different mode for guid skateboard from the prior art.Cunning is exemplarily mentioned herein
Lower moving guide and rolling guide, the rolling guide can be respectively configured to wide guide, narrow guide or center and lead
To part.Rolling guide generally has less gapless and less friction.But roll the damping of guide mechanism（Dä
mpfung）It is smaller.In most cases bothered very much in addition, rolling the manufacture of guide and its accurately installing, and thus
Correspondingly cause higher cost.And known sliding guide piece conversely then has preferably damping, and generally have higher
Rigidity.In order to bear the power from different directions, known crimping-sliding guide piece in addition（Umgriff-Gleitfü
hrung）.Sliding guide piece can be structured as hydrokinetic sliding guide piece, and can be structured as the slip of hydrostatic
Guide.
As the lubricant for sliding guide piece, known multiple fluid from the prior art.The most frequently used lubricant exists
Here it is oil.Therefore, oil is next used as the synonym for every other lubricant.
Sliding guide piece preferably have respectively two toward each other, flat spigot surface.Slip for hydrostatic
For guide, by means of oil pump by oil film be added to it is described toward each other, between the spigot surface of plane, wherein by means of institute
State oil pump the oil film is placed under pressure.The oil film being placed under pressure（Ölfilm）Thus by described in toward each other
, flat spigot surface extruding separates.In other words, it is described toward each other, flat spigot surface is in such hydrostatic
Sliding guide piece in do not contact each other.Therefore the sliding guide piece of hydrostatic is the very low guide mechanism that rubs.Continue
It is described toward each other, the oil that is added between flat spigot surface flows down on the fringe region of the spigot surface.By means of institute
Pump is stated, thus continuously should be added the oil mass equal with the oil mass flowed out on the interface of the side of the spigot surface in institute
State toward each other, between flat spigot surface.Thus, the sliding guide piece of hydrostatic is characterised by higher oil consumption.
For hydrokinetic sliding guide piece, in it is described toward each other, between flat spigot surface
Pressure is produced by the mobilization force caused by the relative motion between two spigot surfaces in oil film.In halted state,
That is it is described toward each other, between flat spigot surface without relative motion when, two spigot surfaces are pressed on one
Rise.Due to the oily attachment between the spigot surface, the oil is in halted state also by without residually from described
Extruded in region between spigot surface.More precisely, in halted state, oil film is maintained between the spigot surface.Institute
State between spigot surface when there is relative motion, it is so-called " oily to produce with the shear stress between corresponding spigot surface by oil
Wedge ".With the rise of relative velocity, the shear stress and thus the pressure in the oil film wedge also raises.Due to the oil
Pressure and by the spigot surface extrude separate.In other words：The spigot surface of hydrokinetic sliding guide piece is relative to each other
Move faster, then by the spigot surface extruding separately it is more remote.Actually, this also referred to as " suspends ".For with
For the grinder of the hydrokinetic sliding guide piece formed between the base and the slide plate, therefore there is also following
It is dangerous：The slide plate suspends relative to the bearing and thus may produce deleterious effect to the accuracy of grinding.Due to
Elevated pressure in the oil film wedge, for hydrokinetic sliding guide piece, at the end of the outside of the spigot surface
Following danger is equally existed on portion edge：Oil can flow out herein.But utterly apparently, the oily amount of outflow is substantially small
The amount flowed out in the sliding guide piece in similar hydrostatic.For hydrokinetic sliding guide piece, only will
Oil film add it is described toward each other, between flat spigot surface, and then will for the sliding guide piece of hydrostatic
Continuous oil stream is added in the space between the spigot surface, and the oil stream is then on the side of the outside of the spigot surface
This space is left on edge.
The content of the invention
Therefore, task of the invention is to provide a kind of grinder, and the slide plate of the grinder can be damaged with oil as few as possible
Mistake is particularly precisely moved and positioned.
The task is resolved by a kind of grinder, and the grinder has base, the slide plate that can be moved, is fixed on institute
The linear steering stated the milling tool unit on slide plate or the base and constructed between the base and the slide plate
Mechanism, the slide plate can be moved by means of channeling direction of the linear steering mechanism along the linear steering mechanism, wherein
The linear steering mechanism has at least one sliding guide piece for being used to bear normal force and at least another is used to bear
The guide of cross force, wherein described or each sliding guide piece include respectively two toward each other, flat spigot surface,
And at least one spigot surface in the spigot surface of wherein described or each sliding guide piece has at least one integrated table
Bin part, the surface element have the lower coefficient of friction of remaining spigot surface more adjacent than accordingly.
Accordingly, the linear steering mechanism includes at least one especially hydrokinetic, for bearing normal force cunning
Lower moving guide.Certainly, the guide for being used to bear cross force can also be configured to corresponding sliding guide piece, or only
Other known guide can also be configured to.It is also contemplated that mixed form.
For the sliding guide piece, using lubricant, especially oily, for can realize the spigot surface,
As unresisted as possible, opposite movement.
According to the present invention, at least one surface element is integrated at least one guiding in the flat spigot surface
In face.Such spigot surface thus by distribution arrange, have lower coefficient of friction surface element and led by described
Formed to remaining surface in face.It consequently leads to：This spigot surface has a variety of different size of coefficient of friction, and these rub
Wipe the different regions that coefficient is correspondingly associated with the flat spigot surface.
In addition, as already explained like that, can during progress relative motion between the spigot surface toward each other
So-called oil film wedge can be produced.This oil film wedge should fatefully be attributed to it is on the interface relative to corresponding spigot surface,
The shear stress to be worked in the oil.The shear stress depends on the coefficient of friction of corresponding spigot surface again.Therefore, it is worth
Pursue, corresponding spigot surface has alap coefficient of friction.In this case, caused shear stress and
Corresponding oil film wedge all very littles, this causes advantageously lesser degree of suspension.
It has been found in practice that there can be especially small coefficient of friction by especially different types of plastics to manufacture
Surface.By surface very firmly and/or made of very hard material coefficient of friction often as a rule apparently higher than
The coefficient of friction of similar softer material.Further it has been found that softer material only possesses less wearability.Thus,
If occurs the contact of machinery between the spigot surface, then following danger is there is for softer material：This
A little spigot surfaces can soon wear and then become at once inaccurate.Therefore, in order to by means of sliding guide piece also chronically
Ensure accurate guiding, it is nonsensical that the whole spigot surface of sliding guide piece is manufactured by softer material.In order to ensure this two
Kind hope, that is, long-term guarantee accurately guide and provide the low guide function that rubs as far as possible, by the grinding of the present invention
Machine has at least one spigot surface of corresponding sliding guide piece, the spigot surface then have it is at least one it is integrated, gather around
There is the surface element of the lower coefficient of friction of remaining spigot surface more adjacent than accordingly.Therefore, integrated surface element can be by
The first plastics or the first plastics are made, and remaining spigot surface then can be by second of plastics or the second plastics system
Into.It should be considered that total friction of such sliding guide piece is by the table with relatively low coefficient of friction in terms of this
Bin part region and remaining（With higher coefficient of friction）Spigot surface region friction part institute group
Into.But in the case where being weighted by corresponding surface share, average coefficient of friction is smaller than on similar surface, institute
Similar surface is stated only to be made up of a kind of material with higher coefficient of friction.Thus, it is a feature of the present invention that being used for
Optimal compromise proposal between grinder, accurate guiding and the low guiding that rubs as far as possible.By for area than
Simple adjustment, corresponding favourable characteristic can be made most preferably to match with the prespecified of reality.
A kind of favourable design of the grinder is characterised by, the guiding of described or each sliding guide piece
At least one spigot surface in face have it is multiple it is integrated, advantageously arranging, possess remaining spigot surface more adjacent than accordingly
The surface element of lower coefficient of friction.Due to this design, it can realize that surface is born on corresponding sliding guide piece
The more preferable distribution of lotus.
Another favourable design of the grinder is characterised by, described or each have relatively low friction
The surface element of coefficient is made up of more halogen alkene, especially polytetrafluoroethylene (PTFE), and the spigot surface accordingly abutted is by artificial
Resin, especially alkyd resin, polyurethane resin, epoxy resin, silicones, vinylester resin or acrylic resin are made,
Or mainly there is corresponding component.Actually, it has been shown that, point between the oil and more halogen alkene of solid
The interaction of less molecule in interlayer be present（Attachment）, and then exist in the boundary layer between the oil and artificial resin
（Comparatively）The interaction of higher molecule.Therefore, adhewsive action and caused friction described in more halogen alkene
Coefficient is significantly less than in the artificial resin.
Another favourable design of the grinder is characterised by, described or each surface element have compared with
Low coefficient of friction, such as less than 0.1 coefficient of friction, and described accordingly adjacent remaining spigot surface have it is higher,
Especially slightly higher coefficient of friction.The average coefficient of friction of corresponding spigot surface by surface share from being determined
Determined in coefficient of friction.In the case of current, the average coefficient of friction is therefore less than 0.15, and thereby guarantee that and rub
Wipe especially low guide function.
Another favourable design of the grinder is characterised by, described or each possess relatively low friction
The material of the surface element of coefficient has the intensity smaller than the material of accordingly adjacent remaining spigot surface and/or just
Property.In other words, the material of accordingly adjacent remaining spigot surface have than（Affiliated spigot surface）It is described or every
The individual high intensity of surface element for possessing lower coefficient of friction and/or high rigidity.It is above interpreted, hydrokinetic
Suspension phenomenon is likely to occur in sliding guide piece.The suspension phenomenon is more severe, it is described toward each other, flat spigot surface just
It is movable with respect to each other faster.But in the case where relative velocity is very low, this effect can ignore that.If for one
For kind sliding guide piece, the spigot surface of the sliding guide piece is moved towards each other with less relative velocity, is unintentionally being existed
Occurs the contact of machinery between the spigot surface, then ensure due to this implementation flexible program, at least substantially by " described
Remaining adjacent spigot surface " bears the power and issuable friction during this.This point should be attributed to phase
Intensity and/or rigidity that should be higher.Since when the contact of machinery be present, " remaining spigot surface of the adjoining " not empress dowager
Move back, and thus prevent at least one surface element for possessing relatively low coefficient of friction to be worn and/or damage.
Another favourable design of the grinder is characterised by that described or each sliding guide piece is put down
At least one spigot surface in smooth spigot surface is interrupted by least one oil supply tank.The oil supply tank is in this implementation flexible program
In occupy a kind of specific position because it is this implementation flexible program in the sense that " flat spigot surface " refer to a kind of surface,
The surface is configured to flat structure in addition to the oil supply tank., can be to the slide-and-guide by means of the oil supply tank
Part, be particularly in it is described toward each other, region between flat spigot surface targetedly fuel feeding.
Another favourable design of the grinder is characterised by that described or each sliding guide piece is led
The slide plate is associated with to one of face, and/or another described corresponding spigot surface is associated with the base, or otherwise also
So.One spigot surface of the sliding guide piece is it is possible thereby to be the integrated part of the slide plate.Additionally or as
Alternative solution is it is also possible that arrange：One spigot surface of the sliding guide piece is the integrated part of the base.
A kind of feature of such design is in particular, in that compact structure, wherein the base and/or the slide plate are formed accordingly

In a general chart from Fig. 1 to Fig. 6, it can be seen that a kind of grinder 2, the grinder have base 4, can moved
Slide plate 6, the milling tool unit 8 being fixed on the slide plate 6 and the line constructed between the base 4 and the slide plate 6
Property guiding mechanism 10, can be along the guiding of the linear steering mechanism 10 by means of slide plate 6 described in the linear steering mechanism
Direction F move, wherein the linear steering mechanism 10 have it is at least one be used for bear normal force sliding guide piece 12 and
At least another guide 14 for being used to bear cross force, wherein described or each sliding guide piece 12 includes two courts respectively
To each other, flat spigot surface 16,17, and in the spigot surface 16 of wherein described or each sliding guide piece 12 at least
One spigot surface has at least one integrated surface element 18, and the surface element possesses remaining than the accordingly adjoining
The lower coefficient of friction of spigot surface 20.
Grinder 2 is fully disclosed by prior art, thus need not carry out detailed view and explanation herein.Principle
On in this respect it is to be noted, that the base 4 is preferably configured as the structure of position fixation, and the slide plate 6 then can be relative to institute
Base 4 is stated relatively to move.If in addition, there is milling tool unit 8 described in capable person to be fixed on the slide plate 6 or the base
Feasible program on 4.Furthermore it is known that the grinder 2 with a base 4 and multiple slide plates 6 that can be moved.It is here, favourable
, the slide plate 6 can move independently of one another.Therefore, for example at least one slide plate 6a, 6b are configured to flatly move
Dynamic structure, and at least another slide plate 6c is configured to the structure being vertically movable.It can accomplish in this way
This point：One of described slide plate 6 holds workpiece to be processed by means of corresponding workpiece base, wherein described
The milling tool unit 8 is secured on another slide plate 6 that can be moved.
In order to move the milling tool 8 as accurately as possible or have workpiece to be processed and/or make its positioning, in institute
State and linear steering mechanism 10 is constructed between base 4 and the slide plate 6.From universal oil well known in the prior art or other
Fluid that is liquid or even sticking, having lubrication is suitable as lubricant.Due to the linear steering mechanism 10, institute
Stating slide plate 6 can move along the channeling direction F.Therefore, the linear steering mechanism 10 especially flows with least one
Body power, sliding guide piece 12 for bearing normal force.In order to ensure to bear normal force as homogeneously as possible, such as in Fig. 1
Shown in as advantageously, the linear steering mechanism 10 have it is multiple it is parallel it is being arranged side by side, for the method for bearing
To the sliding guide piece 12 of power.In this case, less transverse direction is formed in the slide plate 6 and in the base 4
Stress, and the slide plate 6 and/or the base 4 are bent with lesser extent.In order to ensure to guide along channeling direction F
The slide plate 6, the linear steering mechanism 10 have at least another guide 14 for being used to bear cross force in addition.In order to
Crooked phenomenon is avoided during being guided along channeling direction F, herein also advantageously, the linear steering mechanism 10
With multiple guides 14 for being used to bear cross force.In addition, it can be clearly seen that these guides 14 are same from Fig. 1
It is oriented parallel, for can be guided along identical channeling direction F.
In addition, figure 1 illustrates the linear steering mechanism with crimping 11.These crimpings 11 are described for adjusting
The prestressing force of corresponding guide 12,14 and/or gap, and be consequently for improving guiding accuracy.
For grinder 2, the normal force to work is generally much bigger compared with the cross force of effect.Therefore, in reality
On have confirmed particularly advantageously, make corresponding guide 12,14 decoupled from top of one another.As shown in Figure 1 that
Sample, makes that the sliding guide piece for being used to bear normal force and the guide 14 for bearing cross force are decoupled, and method is
Described two guides 12,14 are disposed perpendicularly to each other.Thus cross force is led by the slip for being used to bear normal force
Transmitted to part 12.Similar situation is applied to the guide 14 for being used to bear cross force.It is possible thereby to will be described corresponding
Guide 12,14 be applied to clearly defined objectively it is anticipated that power on.
As previously mentioned, very high normal force is likely to occur in grinder.In order to be kept away along normal direction
Exempt from point-by-point load, the grinder 2 by the present invention is therefore with least one sliding guide piece for being used to bear normal force
12.Described or each sliding guide piece 12 include respectively herein two toward each other, flat spigot surface 16,17.By
The normal force can with planar be transmitted in these spigot surfaces 16,17.In principle, sliding guide piece 12 is people from the prior art
It is known.But these sliding guide pieces carry shortcoming.The sliding guide piece of hydrostatic such as has the disadvantages that：Led described
There is oil stream to go out all the time on to the fringe region of part.For the sliding guide piece of hydrostatic, periodically occur in " during suspension "
The change depending on load of chinky altitude.
In order to overcome the negative effect of known sliding guide piece, the grinder 2 by the present invention has at least
One preferred hydrokinetic sliding guide piece 12, the sliding guide piece have two toward each other, it is flat, for holding
By the spigot surface 16,17 of normal force, wherein at least one guiding in the spigot surface 16 of described or each sliding guide piece 12
Face has at least one integrated surface element 18, and it is low that the surface element then possesses remaining spigot surface 20 more adjacent than accordingly
Coefficient of friction.Provide herein, integrated surface element 18 respectively at least have 1,5,10,20,50,100,200,500,
1000th, 2000 or 5000mm2Area and/or affiliated spigot surface 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%
Or 90%.The flat spigot surface 16 is thus by least one integrated surface element 18 and the spigot surface 16, corresponding
Remaining adjacent surface 20（Its coefficient of friction is higher than the coefficient of friction of at least one surface element）Formed.Due to collection
Into surface element 18 less coefficient of friction, the average coefficient of friction of the whole spigot surface 16 is significantly less than and integrates
The coefficient of friction on surface 20 that abuts of surface element 18, and cause lesser degree of suspension when the slide plate 6 moves.By
This, the oil mass for being lubricated to the sliding guide piece also can be smaller.The degree that the slide plate suspends is smaller, the slide plate
6 just more accurately can move and/or position.
As shown in fig. 3 and in fig. 5, in the spigot surface 16 of described or each sliding guide piece 12 at least
The surface element 18 that one spigot surface is arranged with having multiple integrated, distributions, the surface element possess than accordingly adjoining
The lower coefficient of friction of remaining spigot surface 20.Therefore, the surface element 18 can arbitrarily be distributed in principle.But in reality
Had shown that on border, symmetrical distribution is favourable, because also symmetrically bearing the normal force in this case.By
This can effectively prevent the crooked of the spigot surface 18 toward each other.Integrated surface element is such as shown in figure 3
The distribution situation of 18 island.Fig. 5 shows the distribution feelings of the pattern of integrated surface element 18, automobile tire profile
Condition.It is integrated it is surface element, formed with may be reversed relative to the distribution of remaining spigot surface.
It is described or each with relatively low coefficient of friction surface element 18 advantageously by more halogen alkene, especially poly- four
PVF is made, and the spigot surface 20 accordingly abutted is by artificial resin, especially alkyd resin, polyurethane resin, ring
Either acrylic resin is made or mainly has corresponding component for oxygen tree fat, silicones, vinylester resin.Before having
Component that face is previously mentioned or the spigot surface 16 being made up of component noted earlier at least fifty-fifty have especially low rub
Wipe coefficient.It can be disposed herein：Surface element 18 that is described or each possessing relatively low coefficient of friction has especially
Coefficient of friction less than 0.15 or 0.1, and remaining spigot surface 20 of the accordingly adjoining is with preferably significantly higher
Coefficient of friction.It is also contemplated that other pairing schemes of coefficient of friction, in particular for standing the slide-and-guide of grinder 2
The higher load in the part of part 12.Even if the linear steering mechanism 10 and the common load phase of corresponding grinder 2
Matching, actually there is also following dangerous：Overload causes corresponding sliding guide piece 12, toward each other flat
The aggravation of the friction of smooth spigot surface 16,17.In order to by toward each other flat of corresponding sliding guide piece 12
Spigot surface 16,17 carries out wearing the level for keeping as small as possible accordingly caused by mechanical friction especially unintentionally,
Advantageously, the material of surface element 18 that is described or each possessing relatively low coefficient of friction has than the accordingly adjoining
The material of remaining spigot surface 20 smaller intensity and/or rigidity.It is thus described relative to corresponding adjacent when there is overload
Remaining spigot surface 20 surface element 18 with relatively low coefficient of friction can slightly retreat, so as to the substantially only phase
Remaining spigot surface 20 that should be abutted is subjected to actual mechanical friction.These spigot surfaces due to its higher intensity and/or
It is rigid and relatively more resistant to abrasive wear.Even in the case of there is short-term and/or unexpected overload, the sliding guide piece 12
Such design also there is higher service life to be expected.
It is known that the function of sliding guide piece 12 is even in the spigot surface toward each other from explanation above
16th, also keep constant during the mechanical contact of 17 progress short time.In contact mechanical as appearance, it is described possess it is relatively low
The surface element 18 of coefficient of friction protected by described accordingly adjacent remaining spigot surface 20.Thus It is not necessary to
, continuously larger oil mass is added between the spigot surface 16,17 toward each other.More precisely, use oil film
It is just enough to soak the spigot surface 16,17.In order to ensure this wetting, preferably provide, described or each slide-and-guide
At least one spigot surface in the flat spigot surface 16 of part 12 is interrupted by least one oil supply tank 22.Such oil supply tank 22 exists
Shown in Fig. 5 and 6.This road oil supply tank 22 occupies a kind of specific position herein, because " flat spigot surface in this sense
16 " refer to a kind of surface, and the surface is configured to flat structure in addition to the oil supply tank 22.By means of the oil supply tank
22, can targetedly to the sliding guide piece 12 and especially its it is described toward each other, flat spigot surface
16th, the lubricant between 17 receives the fuel feeding of room 28.Oil is conveyed to by the oil supply gallery 23 behind especially herein described
Oil supply tank 22.If the sliding guide piece 12 is hydrokinetic sliding guide piece 12, then by means of the oil supply tank 22
Can will be added into the lubricant receives the oil mass in room 28 to keep the level of very little, especially remains to minimum degree.
Described " being protected ", possess relatively low coefficient of friction surface element 18 be used for obtain belonging to sliding guide piece 12 must
The slip ability wanted.Due to the less oil mass being added into the lubricant chamber 28 and due to described noted earlier
The relatively low coefficient of friction of surface element 18, or even there is the situation of higher relative velocity between the spigot surface 16,17
Under also only there is lesser degree of suspension.It is described with possessing relatively low friction when speed is relatively low or in halted state
The spigot surface 20 that the surface element 18 of coefficient abuts prevents the breaking-up and/or damage of corresponding sliding guide piece 12.
In principle, the phase to be added for receiving the oil mass in room 28 to depend on the sliding guide piece 12 to the lubricant
The actual load answered.Here, will be it is considered that at least soaking the spigot surface 16,17 with oil film.In order to ensure this
Point, it is advantageous to continuously and/or according to consumption oil mass is added in the spigot surface by means of the oil supply tank 22
16th, the lubricant between 17 is received in room 28.In continuously oil transportation, this amount is preferably smaller than 0.1 l/h/100cm2、0.2
l/h/100cm2、0.5 l/h/100cm2、1 l/h/100cm2、2 l/h/100cm2Or 5 l/h/100cm2（Correspondingly on
