Description
Technical field
The invention belongs to the technical field of quality detection of the rotary part with circumferential distribution pore group, and in particular to one
Circumferential distribution pore group position degree assessment method of the kind based on coordinate transform and array sort.
Background technology
In Mechanical Processing Industry, slewing parts are a kind of critically important parts, are widely used in automobile, aviation, ship
Circumference uniform distribution hole system is often distributed on this kind of part in the industries such as oceangoing ship and industrial robot, as shown in Figure 1, (a) represents band in figure
There is circumferential distribution pore group part schematic diagram, (b) represents the sectional view using part after rotation cutting, and (c) represents part tolerance band
Schematic diagram, to ensure the assembly relation between part, hole group generally requires the very accurate of processing.
Important component of the industrial robot as high-end intelligent manufacturing equipment, automatization level is high, and application places are wide,
It is the important support technology of advanced manufacturing industry.RV retarders and harmonic speed reducer be apply it is main on industrial robot joint
Two class retarders.RV retarders compared with harmonic speed reducer have larger fatigue strength, rigidity and service life, stable drive, thus its
It is widely used in industrial robot transmission system.RV retarders are by gear shaft, planetary gear, Cycloidal Wheel, pinwheel, crank axle, needle tooth
The compositions such as shell and planet carrier.Planet carrier and Cycloidal Wheel are as its important part (hereinafter referred to as part), and machining accuracy is to complete machine
Assembling quality, rotating accuracy and service life have direct influence.The position degree precision of the circle distribution axis hole hole group of part,
Load distribution, transmission capacity, fretting wear and the noise objective of retarder are directly affected, and then influences domestic robot industry
Development, therefore must assure that the position of position degree precision in hole system group between each hole and hole system relative to machining benchmark in processing
Degree of putting precision.
The measurement of domestic device to hole group position degree at present mainly has dedicated gauge and measurement of coordinates two ways with evaluation.Pass through
Dedicated gauge carries out workpiece qualification judgement, simple and easy to operate, but can only to evaluate workpiece qualified or not for the method, it is impossible to
Measure the exact value of position error.And three coordinate measuring machine is measurement of coordinates Typical Representative, can be accurately measured multiple
The location coordinate information of miscellaneous structure and hole group, but measurement beat is longer, it is of high cost, it is suitble to being inspected by random samples under the line of part, and
There are strict requirements to measuring environment, the on-line measurement to production line can not be met.In recent years, for certain part special measurement
The research of instrument has obtained significant progress, and this special purpose measuring instrument generally realizes data processing using software kit, for
Algorithm evaluation in terms of position degree is complex.
In actually detected, if selecting different hole as tangential positioning datum, the tangential deviation of same holes is general
Difference, this causes the final measurement error of workpiece larger, easily causes erroneous judgement.Traditional assessment method is directed to different design requirements,
By the way that carry out coordinate transform is translated or rotated under polar coordinates or rectangular coordinate system, circumferential apertures group position degree is assessed,
It needs to find the extreme point of rotation and judges direction of rotation during evaluation, direction of rotation and rotation angle and the tangential mistake in each hole
Difference is related, and due to the randomness of work pieces process, each each hole of workpiece is not known in tangential offset direction, the judgement of direction of rotation
The concrete condition for workpiece is needed, processing mode is complicated and changeable, is not easy to grasp.
Invention content
In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is that it provides a kind of based on coordinate
