Description

The center of circle aligning method of aviation rotary part machining benchmark circle
Technical field
The present invention relates to aviation rotary part manufacture field, particularly aviation rotary part machining benchmark circle Center of circle aligning method.
Background technology
In the course of processing of aviation rotary part, it is necessary first to reference center's point of part is carried out centering, pass The aligning method of system is in the way of table played by lathe, measures the circumference of the machining benchmark of part to be processed, mainly has two ways, The first carries out centering with the jerk value of the circumference of machining benchmark, it is stipulated that jerk value has been part when being not more than a certain numerical value Centering.It two is by measuring 4 points symmetrical on the circumference of machining benchmark circle 1, to adjust two point of symmetry respectively to lathe rotation The range difference of the table core (distance of the range difference of A Dian Dao center and A ' to center or B Dian Dao center and B ' to center Difference) carry out centering, as shown in Figure 2.Saying from the angle of accurate quantification machining benchmark center, tradition aligning method can not Accurately, the center of the physical location at the center of the machining benchmark circle of part to be processed and the basic circle of theory calls is truly reflected Position deviation amount, because to beat in the benchmark judging part to be processed that table mode measures the round circumference jerk value of machining benchmark Heart position on rotation workbench of machine tool, this judgement is actually rough, and jerk value simply reflects machining benchmark circle The center of circle on rotation workbench of machine tool, be partial to some region of trend, and the particular location in the basic circle center of circle cannot be known, nothing Method quantifies the departure at part actual machining benchmark center and the position of the reference center of theory calls, and becomes at centering thin-walled During the reference center of shape part reference center and the bigger part of circularity the longest.Equally, point of symmetry are measured beating table mode Method to rotation workbench of machine tool central difference is also inaccurate, because the symmetrical measurement point that centering is taken in this way Randomness is big and samples on the low side, by different operators, same machining benchmark is carried out centering or is taken difference by same operator Measuring the point same benchmark of centering, final part to be processed position on rotation workbench of machine tool is all different, this difference Not caused by measurement error, but what aligning method itself was caused, and this difference certainly exists.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of aligning method being applicable to various aviation rotary part, Can accurately, efficiently solve reference center's centering of the bigger situation of circularity of thin-walled deformation part and part to be processed basic circle Problem.
For solving above-mentioned technical problem, the center of circle centering side of the aviation rotary part machining benchmark circle that the present invention provides Method, comprises the steps:
A, set centering coordinate system SCS, and lathe is pressed centering coordinate system SCS back to zero；Part to be measured is substantially placed In rotation workbench of machine tool center, i.e. revolving parts machining benchmark center O1 is big with rotation workbench of machine tool center O Cause to overlap.
B, center to part carry out preliminary centering, beat table mode at centering seat by machine tool on-line measurement technology or tradition Under mark system SCS, uniform measurement four point on the circumference of processed revolving parts machining benchmark circle, it is desirable to symmetrical 2 are arrived The difference of the distance of machine tool rotary center O is less than 20mm, the most slightly compresses part to be processed, and thrust is with at centering During machine tool motion time part is immovable is as the criterion.
C, with online metering system under centering coordinate system SCS, operating measurement program, at revolving parts machining benchmark Circumference on uniform measure n put and by each coordinate points of recording with cartesian coordinate (x, y, z) or polar coordinate (r, θ) shape Formula record, and be fitted calculating with method of least square by above-mentioned numerical value input computer, simulate this n and measure some institute structure The circle become, and export a central coordinate of circle O1(x1, y1, z1), wherein n is the positive integer not less than 8；(the circle depending on machining benchmark circle Depending on degree situation, the value of n is the biggest, and data measured is the most, it is thus achieved that data the most accurate).
D, lathe is pressed centering coordinate system SCS back to zero, remove thrust, with the processing of the part to be processed that step C obtains The centre coordinate O1(x1 of benchmark, y1, z1) it is reference, the X direction under centering coordinate system SCS and Y direction targetedly Upper adjust part position respectively；On Y direction of principal axis, table is first pressed, to the opposite direction moving parts of y1, the distance that need to move during adjustment For absolute value y1, then pressing table on X direction of principal axis, to the opposite direction moving parts of x1, the distance that need to move is absolute value x1, with Making the center of circle and the platen center superposition, the most slightly compressing component of machining benchmark circle, thrust is with during machine tool motion zero Part is immovable to be as the criterion.
This fitting circle reflects the actual state of tested benchmark, and the central coordinate of circle of this basic circle is machining benchmark center O1 Position on rotation workbench of machine tool, because the central coordinate of circle that software matching is calculated is with institute in centering coordinate system SCS The coordinate of n the point measured is that initial data carries out calculating, so the center of circle of the basic circle exported after fitting software calculating Coordinate is exactly the center of circle of the machining benchmark circle of processed rotary part coordinate position 01(x in centering coordinate system SCS, Y, z) or O1(r, θ).Again because the initial point of centering coordinate system overlaps with rotation workbench of machine tool center O, therefore this fitting circle center of circle Coordinate is exactly the reference center of processed revolving parts position 01(x, y on rotation workbench of machine tool, z) or O1(r, θ) 。
The deviation at the reference center of part to be processed and rotation workbench of machine tool center is with the processing base after the matching of n point True centric coordinate figure O1 represents, wherein the size of r value represents the degree that overlaps of O1 with O, and the least then O1 with O of this value overlaps Property is the best.It addition, the concrete orientation that the machining benchmark center O1 of part to be processed is on rotation workbench of machine tool is with O1(x1, y1, Z1) representing, x1, y 1 represents the center of circle X direction, Y on rotation workbench of machine tool of the machining benchmark circle of part to be processed respectively Side-play amount on direction.
Further, in above-mentioned aligning method, further comprising the steps of: on the basis of step D, by centering coordinate system SCS Back to zero, with online metering system under centering coordinate system SCS, operating measurement program, at the machining benchmark circumference of part to be processed Upper the most uniform measuring n again and put and the coordinate points recorded calculated with method of least square method with fitting software again, matching makes new advances Measure the new circle that point is constituted, and export central coordinate of circle O2 (x2, y2, z2) or O2(r2 for n, θ 2), operating personnel is with r2 value For with reference to centering required value (i.e. in the center of circle of the basic circle of the part to be processed that technological procedure specify and rotation workbench of machine tool The distance value of the heart) compare, if r2 is not more than centering required value, then centering terminates, if r2 is beyond requiring so to repeat Aforesaid operations process meets the requirements to r2.
The technique effect of invention: the center of circle aligning method of the aviation rotary part machining benchmark circle of (1) present invention, phase For prior art, after part machining benchmark circle is carried out multimetering, principle of least square method is used to draw the theory of this part Center, compared to " 4 centerings of circumference " or " circumference jerk value centering " principle more science, it is thus achieved that result more accurate；(2) First use 4 centerings to primarily determine that the approximate location in the center of circle of slewing parts basic circle before centering, decrease the adjustment time； (3) the method use secondary centering verify, it is thus achieved that accuracy higher.
