The corresponding views of the three phases in when Fig. 3 is annular object automatic,
View shown in Figure 4 is with respect to the accurate centering ending phase of the pivot at surface of revolution of annular object, and
Fig. 5 illustrates aforementioned according to the device that is in the automatic centering state of the present invention a little in further detail,
That Fig. 6 has shown is aforementioned, according to the part of annular object of the present invention alternative in period automatic centering starting stage on surface of revolution.
The specific embodiment
Fig. 1 has schematically shown a surface of revolution 1, and this surface is around its pivot O slow circumvolve.This surface of revolution 1 is preferably the magnetic chuck of any existing type, but can use equally the grip device that is used for axial clamping of other types.At random place annular object or a workpiece 2 with geometric center A on chuck, owing to placing arbitrarily this object or workpiece, this geometric center departs from the pivot O of surface of revolution 1 usually.In the automatic centering process, magnetic force maintain one low-level, the active force that is subject to being basically parallel to the plane of the surfaces of revolution 1 when workpiece thus allows the workpiece 2 can be removable on chuck when affecting.
In order to realize the centering of workpiece 2, a device 3 is provided, this device be provided in towards with can move radially away from the pivot O of surface of revolution 1, for example by a reciprocating drive unit that does not show with by the guiding of guider 4.According to schematic diagram shown in Figure 1, this device 3 is illustrated as a bar with yoke shape end face 5, this yoke shape end face is towards the surface of revolution center O, and its end is two isolated fingers 6,7 with the bisection bisector of radially extending towards the pivot O of surface of revolution 1.When annular workpieces arbitrarily has been placed on surface 1, the beginning slow circumvolve, when workpiece 2 is located with respect to device 3, make workpiece by the finger 6 of device 3,7 support, and described finger 6,7 shrinks on bisection bisector direction gradually, until workpiece 2 is not subjected to the impact of finger 6,7 in a revolution of surface of revolution 1.
When being positioned at, workpiece 2 is not to be easy to and the finger 6 that installs 3,7 the contact the position time, at first device 3 marches forward to the pivot O footpath of surface of revolution 1, and two fingers 6 of working as the bar 5 of propulsion plant 3, when any one in 7 arrives the external envelope surface of workpiece 2 in forward travel, device 3 will tilt and make two fingers 6,7 all contact the external envelope surface of workpiece in spaced apart position, thereby make workpiece be subjected to the effect of these two isolated power, these two power are all acting on the direction on the surface 1 of slow circumvolve.
Here, device 3 forward travel is used for promoting workpiece 2, keeps this motion until workpiece 2 has been pulled to far position, so that its center A has been crossed and surpass the pivot O of surface of revolution 1, as shown in Figure 2.
Arrive this position when, the forward travel of propulsion plant stops, and slowly contraction of propulsion plant 3 beginnings, as shown in Figure 3.When surface of revolution 1 continues slow circumvolve and produced one 180 ° rotations with respect to position shown in Fig. 1 and 2, the action of workpiece 2 by the device 3 of slow contraction is pushed back to the center O of surface of revolution 1, this timer 3 has come the effect of supporting workpiece by the finger 6,7 at two interval.Short-term in the short-term at the surperficial lower end position place shown in Fig. 1 and 2 relatively and surperficial upper surface shown in Figure 3 can find out at Fig. 1, in 2 and 180 ° of motions that between position shown in Figure 3, surface of revolution 1 is done.
When workpiece 2 has been completed centering, make the pivot O of its geometric center A and surface of revolution 1 be consistent, as shown in Figure 4, propulsion plant 3 continues to back off or shrink, the finger 6,7 of propulsion plant will no longer contact surface of the work, so workpiece will remain on the centered positions place.When this position, the confining force of magnetic chuck can convert a powerful chucking power to, so workpiece can carry out machining, such as grinding or turning processing.
Just can in the situation that do not use measuring instrument and/or calculation element, realize the accurate centering of annular object in this way.
In Fig. 5, shown in further detail surface of revolution 1, it can rotate around center O.Annular element or workpiece 2 are placed on arbitrarily on surface of revolution 1, so the center A of workpiece 2 probably departs from the pivot O of surface of revolution 1, therefore when surface of revolution 1 when center O is rotated, workpiece 2 will produce a swing.Propulsion plant 3 forms a push rod, have one to have two separated fingers 6 at the end towards the pivot of surface of revolution 1,7 bar shape end 5, this propulsion plant in the mode of guiding towards radially removable with the pivot O away from surface of revolution 1.The function of this propulsion plant 3 is identical with the function of parts shown in Fig. 1-4.
When annular workpieces still centering and when therefore swinging, embodiment as shown in Figure 5, propulsion plant 3 or supporting arrangement 3 during movement will be at first with finger 7 contact workpiece, and when initial contact, due to the angle of the collision of frictional force and finger and outer surface of workpiece, workpiece may be subject to one makes it to the component of inner rotary.
Be subject to this active force that will weaken its alignment function for workpiece is avoided, wish at least to design the frictional force of the finger that at first contacts workpiece as far as possible littlely.For realizing this point, as shown in Figure 5, end at finger arranges a gyroscope wheel 8 or a pan, conveyer belt or analog, and driving it rotates in one direction, thereby produce a frictional force component on finger 7 and workpiece 2, be used for the contact of holding workpiece and finger 6,7.
If the annular workpieces diameter of centering is very large, the distance between the end of contact element needs very large, thereby make propulsion plant also become very large, therefore will occupy a very large space with respect to surface of revolution, not too be suitable for the automatic centering of very large-scale annular workpieces according to the scheme shown in the embodiment of Fig. 1 to 5.
Fig. 6 has shown a surface of revolution 1, and this surface is around pivot O slow circumvolve.This surface of revolution 1 is preferably the magnetic chuck of an existing type, but can use equally the grip device that is used for axial clamping of other types.Placed arbitrarily annular object or a workpiece 2 with geometric center A on this chuck, owing to placing arbitrarily this object, this geometric center can depart from the pivot O of surface of revolution 1 usually.In the automatic centering process, magnetic force maintains a reduced levels, when the power that is subject to being in substantially parallel relationship to the plane of the surfaces of revolution 1 when workpiece 2 affects, can move on chuck.
For implementing the centering of workpiece 2, first contact element 13 is provided, this element can be towards moving with pivot O away from surface of revolution 1, for example by a reciprocating drive unit that does not show with by the guiding of guider, contacts the outer surface of annular workpieces 2.
The first contact element 13 be arranged to can illustrated straight arrows 13 ' direction on move, preferably, but not necessarily, it is connected to the sliding system of (not shown) mechanical sliding system on lathe or separation and by the sliding system operation of this machinery sliding system or separation, wherein surface of revolution 1 is formed for a chuck of workpiece 2.
This lathe is preferably, but 2+2 axle cnc machine tool not necessarily.
This device comprises second contact element 14 equally, be used for the outer surface at the position contact annular workpieces 2 that fully separates away from the first contact element 13 and contact position between workpiece, the second contact element 14 illustrated straight arrows 14 ' direction on move in reciprocating mode equally, simultaneously, this second contact element 14 is preferably, but not necessarily be connected on lathe another (not shown) mechanical sliding system and by its operation, wherein, surface of revolution 1 forms a chuck that is used for workpiece 2.In other words, contact element can be connected to an independent sliding system and by its operation.
When annular workpieces has been placed on arbitrarily on surface 1, surface 1 beginning slow circumvolve, when workpiece 2 is located with respect to contact element 13 and 14, workpiece is supported by contact element, element is radial contraction gradually, until workpiece 2 is not subjected to the impact of contact element 13,14 in a swing circle of surface of revolution 1.
When workpiece 2 has been placed complete, be that it has not been to be easy to and contact element 13, during 14 contact, contact element 13, at first 14 advance in the opposite direction simultaneously towards the pivot O of surface of revolution 1, when these two contact elements 13, when any one in 14 arrives the outer surface of workpiece 2 in forward travel, workpiece movable, and two contact elements 13,14 all will be at the outer surface of interval location place contact workpiece, thereby makes workpiece be subjected to the effect of these two isolated power, and these two power are all towards the pivot O directive effect on the surface 1 of slow circumvolve.
Here, the forward travel of contact element 13,14 be used for to promote workpiece 2, continues this motion until this workpiece 2 has been pulled to far position, so that its center A has crossed and surpass the pivot O of surface of revolution 1.
When arriving this position, stop the forward travel of contact element 13,14, slowly recession of contact element 13,14 beginnings.When surface of revolution 1 continued slow circumvolve, by the slow recession action of contact element 13,14, workpiece 2 will push back to the center O of surface of revolution 1, and contact element 13,14 comes supporting workpiece by two isolated contact positions now.
When workpiece 2 centering make the pivot O of its geometric center A and surface of revolution 1 be consistent, contact element 3,4 continues to back off or return, contact element 13,14 will no longer contact surface of the work, so workpiece will remain on its center position.Confining force at this position magnetic chuck can convert a powerful chucking power to, so workpiece can bear machining operations, such as grinding or turning processing.
Just can in the situation that need not to use measuring instrument and/or calculation element, realize the basic accurate centering of annular object in this way.
When workpiece still centering not, and therefore produce when swinging, at first contact element 13 during movement will collide the outer surface of workpiece, and when initial contact workpiece, due to frictional force and depend on that the angle of described contact element collision outer surface of workpiece may to workpiece one component, impel annular workpieces to inner rotary.
Be subject to this undesirable power that will weaken its alignment function for workpiece is avoided, wish that at least the contact element 13 that contacts at first workpiece should be designed to have such frictional force, namely frictional force can push annular workpieces to the center of surface of revolution with joint efforts.For implementing this, be provided with a gyroscope wheel 15 or a pan on contact element 13, it should be driven on a direction of a frictional force component of generation between wheel 15 and workpiece 2 and rotate, and is used for keeping the contacting of wheel 15 of workpiece and contact element 13.The second contact element 14 may also arrange a device, for example a free gyroscope wheel or a conveyer belt 16, and it equally can be driven.
The present invention is not limited to illustrated in accompanying drawing and with the described embodiment of Reference numeral, still, any modification and modification are all possible within the scope of appended claim.
