Description
Technical field
The present invention relates to for the modified grinding machine of operation cylinder and the method for the described cylinder that is used for polishing.
Background technology
Definition " operation cylinder " for example represents the cylinder for the milling train of pressed metal, the cylinder that in paper machine, uses, the cylinder that in oil pressure is used, uses, the axle of motor peculiar to vessel and by substantially all cylinders with industrial significance of metal and nonmetallic materials manufacturing.
The polishing of the specific cylinder of above-mentioned cylinder, particularly milling train or paper machine has at first the various defectives that link to each other with weight with the burden of sizable cylinder.
In fact cylinder has on diameter from 40mm to 2,300mm, on length from 1,000mm to 12, the size of 000mm and scope are from tens daN until the weight of 230-250t.
Give the function of these cylinders and need to process them with the degree of accuracy and the precision of about some thousandths of millimeter.
Therefore the grinding machine that can be used for these cylinders have special characteristic and must not obscure with less and traditional lathe or the similar grinding machine that can not realize in this sense these bruting process.
Known grinding machine generally includes substantially fixing workpiece holder head and tailstock centre movably, the function of workpiece holder head is to make the workpiece rotating of processing, and support in some applications it, tailstock centre can with respect to the workpiece holder head axially mobile and its function provide with respect to the axial benchmark of cylinder and also support in some applications it.
Before the polishing of cylinder must always be arranged the Primary Location stage of cylinder on grinding machine, this is by inserting cylinder to polish between workpiece holder head and the tailstock centre and subsequently it to be supported between the center of the grinding machine that links to each other with head and tailstock centre; In addition, in case of necessity, use the supporting arrangement that is also referred to as support to tighten the described support member of cylinder, in some cases, support is the weight of support cylinder fully, therefore eliminates the support function of head and tailstock centre.Select any in two kinds of solutions about the type of cylinder to be polished and processing to be achieved.
Known technology was imagined substantially before loading cylinder, along the base stand location support of grinding machine in order to hold cylinder to be polished.Various types of supports can be arranged: at the support that is suitable for resisting polishing power in the situation that is supported on the cylinder on the tip or in all other situations, is suitable for the weight of support cylinder.In addition, can be useful on two supports that support fully of cylinder, perhaps in the time must resisting polishing power, at least one can be arranged; Even in the situation of polishing short-coarse cylinder between the center, do not have support at all, etc.At last, after finishing the location of support, equally in this case must be with respect to the sizing tailstock centre of cylinder.All these substantially all activities movable and that be intended to make grinding machine to be fit to hold certain cylinder are defined as the setting of grinding machine.
So the length of the correct location imagination of cylinder on grinding machine by depending on cylinder in the axial direction towards or move tailstock centre and support away from the workpiece holder head tailstock centre and support or the supporting arrangement length with respect to cylinder be positioned at from the variable range place of fixing workpiece holder head.
Tailstock centre and support or supporting arrangement move and adjusting position usually independently, and no matter these setting operations are manual or automatic.
In this case, if on the one hand, manually solution is economical, on the other hand, it needs time and operator to the precision of parts, and automated solution guarantees service speed and precision, but it need to be used for tailstock centre and be used for motion and the controlling organization of each support.
In the situation of manual grinding machine, these problems are serious due to the fact that and more: the cylinder with different length must usually be polished continuously, so these setting operations must realize for each processing, and is quite consuming time.
Especially, at every turn not only must mobile tailstock centre, and must traversing carriage, reason is must measure from the distance of workpiece holder head (it is used as benchmark) at every turn and so must move all supports along cylinder.
Summary of the invention
Therefore overall purpose of the present invention is these and other defective that overcomes known technology.
This purpose realizes that by the grinding machine with feature of appointment in the first independent claims and subsidiary dependent claims claim should be considered to the integral part of this description.
In order to overcome these shortcomings, imagine a kind of grinding machine for the operation cylinder, described grinding machine comprises workpiece holder head and tailstock centre, described workpiece holder head and described tailstock centre band are useful on the center of moving and supporting in some cases the cylinder of processing, wherein said grinding machine comprises mobile device, and described mobile device and described workpiece holder head are with described tailstock centre and may link to each other with support to be used for allowing them to move along common moving direction.
Another advantageous feature of the present invention, the workpiece holder head all links to each other with single worm screw with possible support with tailstock centre, described single worm screw is equipped with two parts with inconsistent helical thread, so that they can move simply, accurately and rapidly.
26S Proteasome Structure and Function feature of the present invention and it become more obvious with reference to accompanying drawing from following description with respect to the advantage of known technology, and accompanying drawing shows the possible possible embodiments of identical invention.
Description of drawings
In the accompanying drawings:
Fig. 1 illustrates the side view according to grinding machine of the present invention;
Fig. 2 illustrates the perspective side elevation view of part of the grinding machine of Fig. 1;
Fig. 3 is in the details of the grinding machine of the figure of front shown in the front view;
Fig. 4 is in the details of the figure of front shown in the side view.
The specific embodiment
With reference to figure 1, this figure shows according to grinding machine of the present invention.
More specifically, represented grinding machine 10 belongs to such type, wherein just processed cylinder is supported by two the pivot spares 81 and 83 that are positioned in workpiece holder head 13 and the tailstock centre 12, and support 20,21,22 is positioned to the cylinder contact and have provide since the cylinder that identical processing causes may be crooked supporting functions.
Should be understood that grinding machine 10 can belong to dissimilar equally, its medium-height trestle is except having above-mentioned functions, the function that also has the total weight of the cylinder that support processing, and workpiece holder head and tailstock centre only have and make it rotate the function that allows it to polish in the part of emery wheel or equivalent instrument, perhaps described support can not exist fully, with the same in the situation of polishing short-coarse cylinder between the center.
The pivot spare 81 that forms in some cases the support member of cylinder 14 can be contained in the inside of the main body of workpiece holder head 13.
On the other hand, motor 71 can be positioned in the rear section, has the associated drive means for rotor 14.
Tailstock centre 12 also comprises main body, this main body since exist the lower part be arranged in this structure two Linear guides 80 and can translation, it is connected with described Linear guide by means of suitable slide block.
Represent that in some cases the removable central part 83 of the second support member of cylinder can be contained in the body interior of tailstock centre 12.
In addition, if being processing, this needs, in the polishing of so-called " carefully " cylinder, like this is exactly for example, tailstock centre 12 can have device in lower part, this allows to generate preload by spring assembly: this preload acts on and guarantees the Continuous Contact between cylinder 14 and two removable central parts 81 and 83 in the axial direction.
Grinding machine 10 also can comprise opposing or supporting bracket 20,21,22.
These also can and must be present in the unit 20 in guiding piece 80 running in the embodiment in figure 1 at least, but substantially at least three unit 20,21 and 22 and usually exist with odd number.Only under specific circumstances, when the geometry needs of cylinder were such, imagination was used the support (that is, not having center bearing bracket) of even number.Therefore, except this particular case, the support group always comprises center bearing bracket 20, or more generally comprises center bearing bracket 20 and two side stands 21 and 22, or four side stands etc.
For this reason, grinding machine 10 comprises that the mobile device that links to each other with workpiece holder head, tailstock centre and support or supporting arrangement is to allow them to move along common moving direction.
In this example, mobile device comprise with workpiece holder head 13, tailstock centre 12 are connected with support, 21 with are connected the worm screw 16 that is connected so that when when rotation, screw rod 16 activates approaching or removing in the same direction, screw rod 16 extends along described direction.
The screw rod that produces with single-piece has two threaded portions 160 and 161, and workpiece holder head 13, tailstock centre 12 and support 20,21 and 22 each relevant sleeve engage with described two threaded portions, and this will be described in more detail below.
For prevent screw rod 16 in rotation oppositely, screw rod is with two threaded portions 160,161, described two threaded portions have inconsistent helical thread, for example preferably have the counterclockwise screw thread of identical pitch and clockwise screw thread.
Should be understood that two independent spiral shape screw rods can imagining equivalently with having support thread replace single screw rod 16, perhaps the latter can not be single-piece, but can be divided into two different pieces.
As in Fig. 3 and 4 more clearly shown in, mobile device also comprise for workpiece holder head 13, tailstock centre 12 are connected with support, 21 with are connected be bonded on screw rod 16 on screw shell connection/disconnecting apparatus of being connected or disconnecting.
In this mode, by acting on connection/disconnecting apparatus, can by actuating screw with any combination simply, accurately and rapidly moving-head 13, tailstock centre 12 and support 20,21,22, promote the stage that arranges of grinding machine.
This feature can be carried out the unit 12,13,20 that will obtain, a large amount of movement combinations of 21 and 22 easily, wherein the symmetric motion of workpiece holder head and tailstock centre is particularly useful in the situation of polishing " carefully " or " Sendzimir " cylinder, and this is described hereinafter.
During the location of head 13 and tailstock centre 12, these must in the same direction, still move (will move towards the end of cylinder) in the opposite direction.In this mode, by actuating screw 16, workpiece holder head 13 is connected with tailstock centre and can be moved to be connected with it towards the end of cylinder 14 and support it.
In this mode, no matter its size, can easily locate cylinder, be arranged in and be in the tram on the grinding machine in case reason is it, head and tailstock centre move until they are correctly located, and lean against the place, end of cylinder to be processed.
This special characteristic also is convenient to give prominence to the mechanism of possibility automatic loading system significantly, and reason is that the exact connect ion of head 13 and cylinder also can obtain (reason is that head can move) with simple bi-axial loading device.
In addition, need in polishing in the described situation of thin cylinder of opposing polishing power, in the situation of odd number support, can keep center bearing bracket to fix and mobile support arm symmetrically; And in the situation of even number support, both can equate to move symmetrically.
More normally, the various moving conditions of the part of the integral part that should be considered to said method can be arranged, wherein most important as follows:
1) support, workpiece holder head and tailstock centre are with respect to the symmetry of the center reference of grinding machine location: nut and screw rod iff two supports are integral, and then owing to the structural form of worm screw, but they are with mobile same distance opposite direction.Simultaneously the nut of workpiece holder head and tailstock centre from screw rod break away from and these two groups therefore keep motionless.After locating support, be integral and break away from nut positioning workpieces fixed mount head and the tailstock centre of support by the nut that makes these.For example this position fixing process can be useful in the situation of the symmetrical cylinder of polishing (for example Sendzimir).
2) symmetry of the asymmetric localization-support of workpiece holder head and tailstock centre location: in this case, synchronously locating support is integral the latter's nut and screw rod.In this mode, by actuating screw, but they are with mobile same distance opposite direction.After locating these two groups, their nut breaks away from from screw rod.At this moment, the nut of workpiece holder head and tailstock centre alternately is integral with screw rod, then at first mobile first group moved another group.
3) support, workpiece holder head and tailstock centre are with respect to the asymmetric localization of the center line of cylinder: in this case, the location group makes the nut of a group and screw rod be integral at every turn, and the nut of other group that does not relate at the volley breaks away from.(for example keeping in the fixing application in the situation of the asymmetric cylinder of polishing (for example typically hot rolling and cold rolling cylinder) or at the workpiece holder head, usually all application except polishing Sendzimir cylinder), this program can be of great use with mobile above part.
Up to the present many substituting of described grinding machine 10 is possible, and all substitute and are considered to integral part of the present invention.
Imagine the selection mechanism of part to be moved, for these each, sleeve 90 comprises cylindrical cover cap and being threaded on the worm screw 16 by means of cover cap self inside.
Each sleeve 90 also can be connected to the unit that moves by means of suitable mechanism.
In principle, should be noted that substituting of conduct brake block hereinafter described, disclosing of providing in this article is provided, the expert of this area also it is contemplated that the solution that other are different; For example, replace brake block, the retention device of unit to be moved can comprise electromagnet, mechanical connecting device, for example steady pin, wedge, movably interfere profile or other similar articles.
In order to illustrate and non-limiting purpose, in these connection/disconnecting apparatus has hereinafter been described, for example brake block.
Connection/the disconnecting apparatus that is used for the sleeve of part to be positioned comprises two arms 91,92 of the structure (workpiece holder head, tailstock centre and support) that is pivoted to part to be moved, and each band be useful on described sleeve 90 engagement end portion 93,94 with the relative free end 95,96 that connects with actuator 97.
Two arms 91,92 have along their main body at their fulcrums of position O ' and O ' ' swinging so that when two free ends 95,96 near the time, opposed end 93,94 leaves, vice versa.
Grinding machine 10 preferably includes single screw rod 16, and head 13 is connected with tailstock centre and support 20,21,22 is equipped with these connection/disconnecting apparatus, and each has specific relevant sleeve.
In this mode, be provided with along a plurality of sleeves of the main body of screw rod, each is used for a connection/disconnecting apparatus.
Can estimating ability with regard to described content: one actuator in activating connection/disconnecting apparatus be when being closed into liner on the relevant sleeve, pass through actuating screw, the same section of grinding machine (head, tailstock centre or support) can be owing to the rotation of screw rod 16 by the control translation, in fact, prevent that the sleeve that rotates from moving along screw rod 16, cause arm to be pivoted to element translation on it.
So can use simple and accurate system moving-head, tailstock centre and support so that they correctly are positioned on the pedestal 11, greatly reduce the setup times of grinding machine 10.
In addition, in this mode, support and head and tailstock centre can start simultaneously or separately with individual command, obtain the very big multifunctionality of grinding machine.
It is contemplated that other substitutes, for example, can differently make for head 13 with for tailstock centre 12 and/or for the mobile device of support, for example by means of the conveyer belt that is connected with trolley wheel, thereby allow the motion of head 13 and tailstock centre 12 and/or support, as mentioned above.
Mobile device can comprise two independent screw rods and two motors equivalently, even in this case, the cost of grinding machine is higher.
In brief, in known technology, the workpiece holder head is that the fact of fixing means that self regarding the workpiece holder head as benchmark realizes the location of cylinder on grinding machine, with respect to all relative dimensions of described reference measurement and the location of realizing cylinder, for the setup times of grinding machine with must have negative consequence with the loading attachment that the latter is used in combination.
In fact these setting operations in the known grinding machine can manually or automatically be realized.
In the previous case, setup times is of crucial importance, and reason is that a series of different operatings of needing accurately to realize are in order to verify their correctness.Under latter event, simplicity and the reliability of the minimizing of setup times infringement grinding machine, reason is that support must be equipped with suitable mobile device and relative control system with tailstock centre.
Another defective that contacts with known technology is relevant with the following fact: at loading days, cylinder must be on three directions and especially, especially also move along longitudinal axis, in order to correctly be positioned on the grinding machine; These adjustment movement need to be used loading attachment.
In manual equipment, this installs typically gantry or whipping crane and movement and the necessary accuracy of location cylinder and need to grow positioning time, skilled operators and faulty operation and can produce and damage cylinder or grinding machine or both risks.In automatic equipment, if the motion of cylinder realizes with 3 axle Load Systems and on the one hand, they reduce the operating time and increase its security, and on the other hand, they need to along 3 axis moving loads and so person's character be complicated, cost is high and the grinding machine of needs maintenance.Support and tailstock centre must move along the cylinder that will correctly locate, in this sense, use conventional art locating support and tailstock centre also very consuming time; With regard to support, for example in the situation of polishing so-called " carefully " or " Sendzimir " cylinder, one is in its sidepiece corresponding to the center line of cylinder location and other substantially, but careful the measurement from the distance of the side of the cylinder that links to each other with the workpiece holder head.Equally in this case, if on the one hand, manually solution is economical, on the other hand, it needs time and operator to the precision of parts, and automated solution guarantees service speed and precision, but it need to be used for tailstock centre and be used for motion and the controlling organization of each support.
By using according to grinding machine 10 of the present invention, can easily realize also should being considered to the localization method of purpose of the present invention, the method always may further comprise the steps:
A-is corresponding to horizontal, the longitudinal centre line plane of locating cylinder at removable workpiece holder head and the datum mark between the tailstock centre of grinding machine;
B-travelling workpiece fixed mount head is connected with tailstock centre that they are connected with cylinder and support it.
The general form of localization method is also imagined following steps:
A1-prepares rolling cylinder to be polished;
A-is corresponding to horizontal, the longitudinal centre line plane of locating cylinder at removable workpiece holder head and the datum mark between the tailstock centre of grinding machine;
B-travelling workpiece fixed mount head is connected with tailstock centre that they are connected with cylinder and support it;
C-laterally is positioned at same distance place from described centre bearing support with at least two support-side supports of described cylinder or supporting arrangement.
The datum mark of in above steps A, mentioning can with corresponding to fixed support with respect to the framework of grinding machine and/or with respect to side stand location cylinder laterally, the longitudinal centre line plane is consistent.
Many modification can be applied to described method significantly, overall purpose of the present invention; In this sense, can put upside down some steps (for example step B. can exchange with C.) of method or can increase other step of regulating relevant method with the secondary of grinding machine; Perhaps also may be because the specific modality of cylinder and geometry and can not use center bearing bracket.
Refer step A, datum mark, this preferably be fixed on the grinding machine and with support or supporting arrangement, particularly consistent with center bearing bracket; Can remove significantly the cylinder of this support to allow polishing to have specific modality and geometry.
Thereby it is always equidistant from datum mark that workpiece holder head and tailstock centre can preferably be moved: in other words, but their movement degree is identical and always in the same direction in the opposite direction realization.
About side stand, that is, be positioned at the support of the sidepiece of the center bearing bracket consistent with datum mark equally, these can be advantageously on same degree and in the same direction, but mobile in the opposite direction.Can be provided with in the both sides with respect to center bearing bracket one or more in these side stands, but always with equal number.
In this mode, obtain above-mentioned advantage, reason is that the datum mark of whole positioning stage no longer is the end of cylinder, but its center line, therefore overcomes the shortcoming of known technology.
So realized in the purpose described in the preface of specification.
