Detailed description of the invention
For making object of the invention process, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is further described in more detail.In the accompanying drawings, same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Described embodiment is the present invention's part embodiment, instead of whole embodiments.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
In describing the invention; it will be appreciated that; term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear", "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " etc. instruction orientation or position relationship be based on orientation shown in the drawings or position relationship; be only the present invention for convenience of description and simplified characterization; instead of instruction or imply indication device or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limiting the scope of the invention.
Front elevational schematic when Fig. 1 is workpiece first clamping.Schematic side view when Fig. 2 is workpiece first clamping.Schematic top plan view when Fig. 3 is workpiece first clamping.With side opening 2 on workpiece 1.The side opening axis horizontal of side opening 2 extends.Side opening 2 needs tune processing.The side opening axis can finding out side opening 2 has an angle with Y direction during first clamping, and this angle is the angle reversing end for end to be transferred to.Such as, this angle is 23 degree, and the adjustment unit angle of lathe is 3 degree, and 23 degree is not the integral multiple of adjustment unit angle.Z axis during first clamping vertically extends, and Z benchmark is the bottom surface of workpiece 1.In this embodiment, described side opening axis is on horizontal plane when first clamping, but the present invention is not limited thereto.Described side opening axis also can with respect to the horizontal plane have a certain degree when first clamping.
Front elevational schematic when Fig. 4 is workpiece secondary clamping.Schematic side view when Fig. 5 is workpiece secondary clamping.Schematic top plan view when Fig. 6 is workpiece secondary clamping.
When secondary clamping, workpiece 1 is rotated an angle relative to Y direction during first clamping, such as rotate 7 degree, then lathe is turned one and turn angle, such as 30 degree (being the integral multiple of adjustment unit angle), thus, the side opening axis of workpiece 1 can be made parallel with the Y direction after secondary clamping.Now, can contralateral exposure 2 process easily.For the ease of determining the anglec of rotation of workpiece 1, advantageously adopt the mode of beating table centering to determine the adjustment angle that described workpiece rotates relative to described initial coordinate system.
In figure illustrated embodiment, the Z axis of side opening Cutter coordinate system when processing described side opening is parallel to the Z axis of initial coordinate system.But the present invention is not limited thereto.If described side opening axis with respect to the horizontal plane has a certain degree when first clamping, then the Z-direction after secondary clamping can relative to the Z axis of initial coordinate system at an angle.
Advantageously, the X benchmark of side opening Cutter coordinate system is determined by the technical face 3 with described side opening axes normal.In a preferred embodiment, technical face 3 carries out machine-shaping between workpiece after first clamping is with the workpiece of side opening and described in secondary clamping.Thus, described technical face 3 can be formed with higher precision.Be understandable that, technical face 3 also can be perpendicular to bottom surface and be parallel to the face of side opening axis.
In a preferred embodiment, described adjustment angle and described initial angle sum equal zero degree.That is, contrary with the direction of initial angle to the adjustment direction of workpiece 1.Thus side opening axis is rotated as the parallel position of initial coordinate system Y-axis.Process can be simplified further like this.
The present invention relates generally to mould by a kind of processing method in " 3+2 " Digit Control Machine Tool process, and namely when non-standard angle side opening appears in mould side, " 3+2 " Digit Control Machine Tool is because a kind of method adopted when having an axle cannot be transferred to required angle.(" 3+2 " lathe has the C axle that rotates around Z axis and Z axis is turned the A/B axle of angle, but be different from five-axis linkage machine tools be " 3+2 " lathe add man-hour A axle and C axle inactive, in advance the angle of main shaft can only be arranged a constant.）
The inventive method be utilize lathe to turn machining benchmark that the function of coordinate system and workpiece stay before turning carrys out centering, workpiece is made to turn an angle, added up with former side opening axis angle by this angle, form the angle that a lathe can be turned, non-standard angle side opening can be processed smoothly.Therefore for correct processing, the first coordinate system that will find second time processing, second will turn the angle that lathe can realize.Therefore must add for the first time and man-hour benchmark be stayed.The function simultaneously utilizing lathe arbitrarily angledly can turn lathe coordinate system beats table centering, thus correct in hole machined smoothly.
Whole process needs to complete in two steps.The first step is the processing of normal clamping, and object is the centering benchmark after processing is turned.Second time turns clamping processing, and object has been the requirement of workpiece side hole machined.
Because workpiece is clamping processing at twice, and the coordinate system of twice clamping is not consistent, so twice processing must specify coordinate system to prevent mistake.First after will turning when lathe normal process, required machining benchmark stays, and benchmark comprises X, Y, Z tri-directions, determines to need to stay those benchmark according to the direction difference that workpiece need be turned.The principle of benchmark is stayed to be, after turning angle in the future, X, Y, Z tri-coordinates all can be found.Namely can find smoothly and turn later Cutter coordinate system.Now milling benchmark with the axis being parallel in hole or vertical, also will can perform tool setting in conjunction with numerical control program.Coordinate system benchmark Z as illustrated this workpiece is determined by bottom surface; X-direction can be turned front at an inessential position milling in advance cutter, makes stayed benchmark parallel with axially bored line, after turning, just can determine X-coordinate.Y-direction coordinate can use tool setting program to carry out tool setting to establish after being established by X and Z coordinate.
Then lathe coordinate system is turned angle, turning angle is side opening axis and machine spindle angle angle, if this signal part angle is the angle 23 degree with Y-axis; When now lathe moves along X-axis separately, be along becoming the direction of 23 degree to move with X-axis in fact.Like this, by dial gauge centering, when workpiece is parallel with the X-axis direction of motion, reality is convenient allows workpiece have rotated 23 degree accurately.Now workpiece is put as Fig. 2, and side opening axis is parallel with Y-axis, now only needs loaded onto by 90 of lathe standard configuration degree of heads or will cutter shaft just can be made after omnipotent head 90-degree rotation consistent with hole axle.
Can machined smoothly after finally workpiece coordinate system being found by stayed benchmark.
This inventive method can by lathe when not meeting the demands (have " 3+2 " lathe but can not five-axle linkage) some hole can not reversing end for end to process utilize existing resource at hand to process smoothly.Relative to traditional machine tool processing method, it can process the hole that originally cannot process smoothly accurately; Relative to the mode changing Design of Dies, it can reduce cost of labor, reduce workpiece machining cycle.
Finally it is to be noted: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit.Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
