The specific embodiment
Core of the present invention provides a kind of free-form surface processing device of structure optimization, with effectively controlling on the basis of lathe manufacturing cost, improves working (machining) efficiency.Specify preferred embodiment below in conjunction with Figure of description.
See also Fig. 1, this illustrates a kind of structural representation of free-form surface processing device.
As shown in Figure 1, this free-form surface processing device comprise workpiece spindle unit 1, drive the driver element 2 that rotates workpiece spindle unit 1, the workpiece spindle feed unit (not shown) that drives workpiece spindle unit 1 rapid axial displacement, knife unit 3 and drive knife unit 3 slow axis to the tool feeding unit (not shown) of radial displacement; Also comprise the shaft coupling 4 that is arranged between workpiece spindle unit 1 and the driver element 2, this driver element 2 is fixedly installed and workpiece spindle unit 1 can be with respect to driver element 2 axial displacements.
Need to prove, the related workpiece spindle feed unit of this programme is identical with prior art with the tool feeding unit, those skilled in the art can realize fully based on prior art, such as, the workpiece spindle unit is arranged on one can carry out on the straight-line slide unit, and slide unit drives by a quick linear moving mechanism; Be provided with one in the place ahead of workpiece spindle unit and drive knife unit relative to workpiece 10 carries out axially and radial alignment moves cutter slide unit etc.Therefore this paper repeats no more.
Following the position of free form surface each point is described by the cylindrical coordinates system.
Z=f (C, X), and the coordinate Z of free form surface is decomposed into Rotational Symmetry part Z1 and non-rotating symmetric part Z2.The slower traditional cutter slide unit of Rotational Symmetry part Z1=f1 (X) Negotiation speed that motion amplitude is larger is realized, and the less non-rotating symmetric part Z2=f2 (C, X) of motion amplitude realizes by the workpiece spindle unit.In fact, on the cutter slide unit simultaneously installation car, mill, the cutter such as grinding, realize that clamped one time finishes roughing, the operations such as semifinishing and fine finishining; Several cutting tools only need a cover fast feed system (Z2).All cutter is contained on the slow cutter slide unit, and non-rotating symmetric part is finished by the motion of workpiece spindle unit.In summary, Z1, Z2, C and X interlock can realize describing the integrated motion of free form surface:
Z=Z1+Z2=f1(X)+f2(C,X)。
In the course of work, because but driver element and workpiece spindle circumferential clocking of turbine rotate and can axially break away from, and driver element is fixedly installed, and the quality of actual required fast moving part farthest reduces, thereby has improved reliably the acceleration of fast feed when equal-wattage.Particularly, please in the lump referring to Fig. 2, the figure shows the assembly relation schematic diagram of described shaft coupling.
Workpiece spindle unit 1 comprises workpiece spindle nose 11, workpiece spindle 12 and collet 13 in this programme; Wherein, workpiece spindle nose 11 links to each other with the workpiece spindle feed unit, to realize the fast offset of workpiece spindle; One end of workpiece spindle 12 is connected with the output shaft of servomotor by coupling band 41, and its free end is fixedly connected with collet 13 after described workpiece spindle nose 11 stretches out; One end of this collet 13 has the jaw 131 of holding workpiece 10, compresses mutually with collet 13 outers of workpiece spindle nose 11 opposite sides and its, so that jaw 131 is regained or opened, realizes clamping work pieces or the operation of unclamping workpiece.That is to say, under the effect of workpiece spindle feed unit, when workpiece spindle nose 11 to workpiece direction displacement first apart from the time, collet 13 compresses and produces shape deforming clip clamping of workpieces 10 with the outer face of workpiece spindle nose 11, and when the 11 reverse displacements first of workpiece spindle nose apart from the time, collet 13 separates with workpiece spindle nose 11 and unclamps workpiece 10.
This paper said " first distance " is so that collet produces the strain clamping work pieces unclamps in the process of workpiece to recovering distortion, the axial displacement that workpiece spindle nose 11 is required.
Further, workpiece spindle unit 1 also comprises limiting component 14 and elastomeric element 15; Wherein, be threaded between the workpiece spindle 12 of limiting component 14 and workpiece spindle nose 11 opposite sides, to regulate the axial distance between limiting component 14 and the workpiece spindle nose 11; Certainly, comparatively simply add the formula device for using operating mode, also can adopt the mode that is fixedly connected with of non-dismountable formula between limiting component 14 and the workpiece spindle 12.
As shown in Figure 2, elastomeric element 15 adopts the disk spring that is sleeved on the workpiece spindle 12.This disk spring is through being arranged on after the precommpression between workpiece spindle nose 11 and the limiting component 14, and under this state, collet 13 jaws 131 that are arranged on workpiece spindle nose 11 opposite sides are the clamping work pieces shape; That is, under the normality, jaw 131 is in the clamping shape.Should be appreciated that the restriction for different workpieces, different grip size, keep jaw under the normality to be in clamping shape must need to regulate axial distance between limiting component 14 and the workpiece spindle nose 11.
In addition, for the above-mentioned design of under the effect of workpiece spindle feed unit, finishing clamping workpiece, has default second distance in this programme between the output shaft of servomotor and the workpiece spindle, workpiece spindle 12 can axial displacement in the second distance scope with respect to motor output shaft, satisfies the processing needs of fast feed.Second distance need to be less than aforementioned the first distance.For ease of describing its operation principle, axial displacement first distance of unclamping workpiece 10 can be divided into two stages considerations: in the phase I, workpiece spindle nose 11 is behind workpiece 10 rightabout displacement second distances, and workpiece spindle and output shaft offset; Continuing to promote workpiece spindle nose 11 this moment continues to the displacement of workpiece rightabout, then enter second stage, until workpiece spindle nose 11 displacements the first distance, workpiece spindle nose 11 will promote disk spring and produce compression, like this, thus workpiece spindle nose 11 separates with collet 13 and recovers distortion and unclamp workpiece.Matching relationship during releasing orientation between each parts sees also Fig. 3.Otherwise, when workpiece spindle nose 11 to workpiece 10 direction displacements the first distance, disk spring acts on limiting component 14 and workpiece spindle nose 11, this moment collet 13 jaw 131 be the clamping work pieces shape.
Certainly, elastomeric element 15 is not limited to the disk spring shown in the figure, in fact also can select compression helical spring or other elastomeric materials to make; In addition, the shaft coupling that is used for connection servomotor and workpiece spindle also can adopt the versions such as magnetic coupling or sliding friction spline to realize.As long as satisfy the demand all in the scope that the application asks for protection.
In order to satisfy between the two the axially use needs of relative sliding and circumferential clocking of turbine rotation, has the static pressure gap of circumferential setting between the output shaft of coupling band 41 and driver element 2; Simultaneously, the pressure medium pipeline is communicated with this static pressure gap, with under the effect of pressed gas or pressure fluid, keeps reliably axial sliding fit between the two.Particularly, pressure medium is selected gases at high pressure, and then the static pressure gap should be set to the 5-30 micron; Pressure medium is selected highly pressurised liquid, and then the static pressure gap should be set to the 10-50 micron.
In addition, the angular encoder (not shown) in this programme is arranged on the servomotor, with the angle signal that obtains workpiece spindle and the driver that feeds back to servomotor, with the turned position of the described workpiece spindle of closed-loop control.Compared with prior art, this programme can remove the angular encoder on the workpiece spindle and read head, and directly uses the angular encoder of drive motors inside, thereby further reduces the quality that needs acceleration, improves acceleration and working (machining) efficiency.
Preferably, knife unit 3 has at least a cutter, such as, on cutter slide unit at a slow speed, lathe tool can be installed simultaneously, bistrique and milling head, and with the rough cut that can realize free form surface once cover fast driving system, half essence cutting and essence are cut, but thereby with further Effective Raise machining accuracy and production efficiency, reduce the production cost of lathe.In aforementioned the first embodiment, cutter can be selected milling head or bistrique, and three kinds of embodiment that different cutters are set below are provided.
See also Fig. 4, this figure is the structural representation of free-form surface processing device described in the second specific embodiment; Cutter in this scheme is that a lathe tool and one are around the rotating tool spindle of self axis.On the tool spindle milling cutter or bistrique can be installed, the clamped one time workpiece just can carry out turning and milling or grinding, and the realization clamped one time is finished roughing and accurately machined technique.Improve working (machining) efficiency and precision.
See also Fig. 5, this figure is the structural representation of free-form surface processing device described in the third specific embodiment; Cutter in this scheme is the combination of three cutters, such as three lathe tools, or milling tool of two lathe tools, or one milling tool of lathe tool and a grinding tool, thereby can select different tool combinations according to the material of workpiece to be machined, realize best machining accuracy and efficient.
See also Fig. 6, this figure is the structural representation of free-form surface processing device described in the 4th kind of specific embodiment; Cutter in this scheme is a lathe tool.
Above-mentioned three kinds of embodiments only are the different of knife combination mode from the difference of the first embodiment, and other compositions and annexation and the first embodiment are identical, do not repeat them here.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
