But, be no matter that common ball tip or dish type tip provide the dirigibility and the precision that in crucial or special high speed, high-acruracy survey task, require.
Summary of the invention
Solution
Therefore, the present invention proposes a kind of probe-type equipment for surveying instrument, comprise rod-like stem (rod-shaped stem) and the contact tip with described rod-like stem attached (attach), wherein, described contact tip is tubbiness (barrel-shaped) normally.
Term " tubbiness tip " refer to there is rounded bottom surface or end face, middle outwardly right cylinder.The radius of the radius of outwardly cylindrical wall or the cylindrical end face of ratio of curvature tubbiness or bottom surface is large.In side view, the radius of outwardly cylindrical wall or curvature are also obviously greater than the half of barrel-shaped cylinder height.In the region of the outwardly cylindrical wall at tubbiness tip, have a barrel equator (barrel equator), this barrel of equator extended to the bucket equatorial radius definition of the most advanced and sophisticated central axis of tubbiness (Z) and had maximum transversal extension (X, Y) by orthogonal.
Point-device measurement can be realized with low hertz of contact stress at for example slot most advanced and sophisticated and that be touched between face in tubbiness tip.This is because tubbiness contact tip allows tip end surface to have the front end face of relatively large radius (or compared with small curve), thereby reduces a hertz contact stress.It is most advanced and sophisticated with to be touched this hertz contact stress between face very little.Tubbiness is most advanced and sophisticated allows most advanced and sophisticatedly in the hole of minor diameter relatively, have larger contact radius.In addition, tubbiness is most advanced and sophisticated allows to exist transverse pitch action in the time of cross measure, and can not cause obvious measuring error.
In a preferred embodiment of probe-type equipment, the end of tubbiness contact tip has less bucket radius, the Chi Daochu of tubbiness contact tip has larger bucket radius, and the less bucket radius of tubbiness contact tip is 0.5 to 0.97 with the ratio of larger bucket radius.
In another preferred embodiment of probe-type equipment, the bucket equatorial radius of tubbiness contact tip is 0.06 to 0.5 with the ratio of bucket radius-of-curvature.The situation that this bent bodies shape that is specially adapted to tubbiness contact tip in side view overlaps with the circle (partly) with barrel radius-of-curvature.
In the another preferred embodiment of probe-type equipment, in the time of the symmetrical shaping of contact tip, the bucket equatorial radius of tubbiness contact tip is 0.2 to 0.45 with barrel long ratio; In the time of the asymmetric shaping of contact tip, the bucket equatorial radius of tubbiness contact tip is 0.3 to 0.8 with barrel long ratio.
In addition, in another preferred embodiment of probe-type equipment, it is long long with bar that tubbiness contact tip and rod-like stem have respectively bucket, and bucket ratio long and that bar is long is 0.07 to 2.
In addition, tubbiness contact tip may comprise proximal part and distal portions, and wherein, proximal part extends to the equator of tubbiness contact tip from bar, and distal portions extends to the free end of tubbiness contact tip from the equator of tubbiness contact tip.In one embodiment, the length of the upper distal portions of Z direction (longitudinal axis of probe-type equipment) and proximal part is equal in length.This is to have symmetrical barrel-shaped situation.
In addition, the distal portions of tubbiness contact tip and the Length Ratio of proximal part can be 0.15 to 1, but can not equal 1, make contact tip normally asymmetric barrel-shaped.Can realize so point-device cross measure, also be in close proximity to the ground with boring, step or groove.In another embodiment, contact tip is also asymmetric barrel-shaped conventionally, but the Length Ratio of distal portions and proximal part is 1.5 to 2.In a rear embodiment, the shape of contact tip quite approaches onion shape.
In the another preferred embodiment of probe-type equipment, the free end of contact tip has curved surface shape, and the free end radius-of-curvature of contact tip is 0.3 ~ 3.5 with the ratio of bucket radius-of-curvature.
In the another preferred embodiment of probe-type equipment, the free end of contact tip has curved surface shape, and the bucket equatorial radius of contact tip and the ratio of free end radius-of-curvature are 0.06 ~ 0.5.
Bucket equatorial radius may equate with the ratio 0.06 ~ 0.5 of free end radius-of-curvature with ratio and the bucket equatorial radius of bucket radius-of-curvature.
Due to its physical construction/shape/framework, when the contact force of probe-type equipment of the prior art is measured in Z direction from the time that X, Y-direction are measured, be different.Conventionally,, compared with X, Y-direction, in Z direction, may change with the factor (factor) 3-15.This causes being subject on surface of the work different stress.For relatively soft workpiece material, add to use and measure micro-structure (for example hole) necessary small-sized probe-type equipment (especially spherical probes), may cause serious problem.
Current disclosed probe-type equipment allows the bucket radius of probe because of the geometric configuration difference of workpiece, thereby make probe X, Y with in Z direction, there is similar even identical hertz pressure (geometric configuration of suppose material behavior and workpiece is identical, and in X, Y and Z direction, measuring sonde is with respect to the obviously difference of contact force of workpiece).
Rod-like stem has radius, and the bucket equatorial radius of probe-type equipment and the ratio of rod-like stem radius are 1 to 2.
Asymmetrical barrel-shaped shape is conducive to the scalariform hole of measurement or very thin scalariform workpiece.
Utilize the seat calibration method in the boring that above arbitrary probe-type device measuring comprises internal whorl, comprise the following steps:
(a) probe-type equipment is inserted in threaded bore (being parallel to the longitudinal axis of this boring), until for example, align with the chamber portion of screw thread towards upper substantially at first of coordinate to be measured (X or Y coordinate) in the region at the place, equator of tubbiness contact tip.
(b) for example, move described probe-type equipment towards the chamber portion of described screw thread first direction (X-axis positive dirction) is upper, until described tubbiness contact tip contacts with described chamber portion.
(c) read the first coordinate figure of described tubbiness contact tip and described chamber portion contact position.
(d) for example, move described probe-type equipment towards the chamber portion of described screw thread second direction (X-axis negative direction) is upper, until described tubbiness contact tip and described chamber portion disengage, wherein said second direction is contrary with described first direction.
(e) move described probe-type equipment (for example continuing to go deep in described boring) along the axle of threaded bore, until half helical pitch or the pitch of mobile screw thread, so that the region at the place, equator of described tubbiness contact tip coordinate to be measured second towards on substantially align with the chamber portion of screw thread, wherein said second towards with described first towards the opposite.
(f) for example, move described probe-type equipment towards the chamber portion of described screw thread second direction (X-axis negative direction) is upper, until described tubbiness contact tip contacts with described chamber portion, wherein said second direction is contrary with described first direction.
(g) read the second coordinate figure of described tubbiness contact tip and described chamber portion contact position.And
(h) get the mean value of described the first coordinate figure and described the second coordinate figure, with the axle that obtains threaded bore in the position of measuring in coordinate system.
Helical pitch is along the axle of screw thread, the distance that a complete thread rotation round (360 °) covers.Pitch is the distance from a thread cavity portion to another bung flange chamber portion.Because most screw thread forms are all single thread shapes, therefore their helical pitch and pitch are all identical.
Because the accurate location of screw thread is unknown, even its equator of tubbiness contact tip often cannot contact with the chamber portion of screw thread exactly.Therefore, can produce measuring error.But this error of tubbiness contact tip is significantly less than above-mentioned spherical or dish type contact tip.But, because pitch or the helical pitch of screw thread are known, can very accurately move axially a half-distance of pitch or the helical pitch of screw thread.Contact on the y direction of the boring on opposite side radially, above or below at a distance of the screw thread of thread pitch or helical pitch one half-distance, can cause same measuring error, but there is contrary symbol.Therefore, can process these error counteractings by averaging.The result of processing of averaging is exactly the accurate coordinates value of the position of the axle of threaded bore.By this processing, roughly align with the chamber portion of screw thread in the region, equator of tubbiness contact tip, and this is no problem.Region, equator refers to and extends to 0 of the proximal part of this contact tip and/or distal portions from the equator of tubbiness contact tip ... 25% circumference band.
