Fig. 3 measuring blocks use schematic diagram；
Fig. 4 measuring block design outline figures.
Specific implementation mode
The embodiment of the present invention is described below in detail, the embodiment is exemplary, it is intended to for explaining the present invention, and It is not considered as limiting the invention.
The purpose of the invention is to quickly establish inclined-plane ignition hole coordinate system, workpiece clamping centering trial cut repeatedly is reduced The Operational preparation time makes simple and quick, raising Working position precision, reduction matter caused by coordinate system deviation tool-setting error Risk is measured, Efficient CNC machining equipment capacity is made preferably to be played.
For the workpiece blank with 45 ° of worktable rotary, the center O for establishing workpiece coordinate system is accurately found2, Cai Nenggao The completion process of effect.Accordingly the present invention devise dedicated measuring block carry out workpiece to knife, can accurately find workpiece rotation O after turning2Position relative to main axle cutter.
As shown in figure 4, the measuring block of the fast run-up inclined-plane coordinate system, including the chamfered region of side and the other side to knife Region.
Rectangular channel of the chamfered region by V-groove and in V-groove bottom forms；The plane of symmetry of V-groove and rectangular channel It overlaps；The two sides of V-groove are in 90 °, and requirement on machining accuracy is interior at 90 ° ± 10 '；The surface roughness upper limit of V-groove two sides It is 1.6 μm；The intersection that rectangle groove deep meets V-groove two sides elongated surfaces is in requirement in rectangular channel.
Described is a rectangular area, the plane of symmetry and V-groove and the plane of symmetry weight of rectangular channel of rectangular area to knife region It closes；For rectangular area tool there are three to knife face, three surface roughness upper limits to knife face are 1.6 μm.
In measuring block, the intersection of V-groove two sides elongated surfaces with to knife sections bottom at a distance from knife face it is known that knife area The domain sides Liang Ge are to known to the distance of knife face.
As long as from figure 3, it can be seen that can determine K2The position of point, O2The position of point just uniquely determines, and measuring block will The coordinate position conversion processing of point, by the sensor probe of Machinetool workpiece centering measuring system, X-direction is to knife face, Z in figure Direction carries out three face detections to knife face, determines K2Point, and then O can be conversed2The coordinate of point.
According to the profile diagram that measuring block in Fig. 4 designs, the precision of measuring block mainly by two inclined-planes (chamfered region) precision and The precision of groove (to knife region) determines, after gauge block process finishing to be measured, to be demarcated to the relative dimensions of measuring block.It measures Electrical discharge machining can be used in block, and the size that tolerance is labeled in figure is all to need the size controlled in processing.When actual processing, knife The size of block is expressed by drawing software, for correcting size conversion.The angle of measuring block is according to processing bevel angle It is differently formed Seriation Design, to adapt to processing environment, convenient for workpiece to knife.
Processing boss face greasy dirt etc. need to be wiped clearly when measuring block use, then will with 502 bonding agents of strength of a small amount of moment It is closely bonded on one corner angle of workpiece boss.
Although the embodiments of the present invention has been shown and described above, it is to be understood that above-described embodiment is example Property, it is not considered as limiting the invention, those skilled in the art are not departing from the principle of the present invention and objective In the case of can make changes, modifications, alterations, and variations to the above described embodiments within the scope of the invention.
