Abstract

The invention relates to a method for correcting a rolling wheel molded line, and aims to solve the conventional problems of low efficiency and inaccuracy of correcting the rolling wheel molded line by workers according to experience. The method comprises the following steps of: 1, drawing the rolling wheel molded line according to a proportion of 1 to 1 based on an uncorrected rolling wheel, drawing the highest control point straight line which passes by a control point of the rolling wheel molded line of the rolling wheel with the maximum diameter, and is parallel to the rotary central line of the rolling wheel, and selecting an end point of the straight line in the molded line and an end point of a circular arc as control points to be corrected; 2, selecting the straight line and the control points to be corrected as correction points, inputting respective parameters, calculating a height of each molded line control point of the rolling wheel, and determining the corrected molded line control points; and 3, connecting the corrected molded line control points by the straight line or the circular arc according to the uncorrected rolling wheel molded line, and thus obtaining the corrected rolling wheel molded line. The method is mainly used for correcting the rolling wheel molded line. By the method, during correction, the precision and the work efficiency are improved.

Description

A kind of correction rolling wheel set molded lines method
Technical field
The present invention relates to a kind of correction rolling wheel set molded lines method.
Background technology
The correction of rolling wheel set molded lines all is to revise by workman's working experience at present; But because the molded lines control point is many; Correction is big (every kind of blade root milling cutter molded lines has about 30 control points) very, uses this method efficient very low, and correction is not very accurately.
Summary of the invention
The objective of the invention is rule of thumb to carry out the low and coarse problem of rolling wheel set molded lines correction efficient, a kind of correction rolling wheel set molded lines method is provided in order to solve present workman.
Following steps of the present invention:
Step 1: the rolling wheel set based on before revising goes out the rolling wheel set molded lines by 1: 1 scale; Draw again the maximum gauge through rolling wheel set the rolling wheel set molded lines the control point and with the highest molded lines control point straight line of the centre of gyration line parallel of rolling wheel set, select out the molded lines control point that the end points conduct of end points and the circular arc of the straight line in the rolling wheel set molded lines will be revised again;
Step 2: select straight line and the molded lines control point that respectively will revise as adjusting point, input cutter tooth number Z, milling cutter relief grinding amount K, milling cutter maximum radius R, said milling cutter employed instrument during for correction rolling wheel set molded lines; The molded lines control point height
Figure BDA0000105275060000011
that calculates rolling wheel set wherein; R is the maximum exradius of milling cutter; H is that milling cutter radially cuts the form height degree; E is the eccentric throw of the approximate circular arc of the milling cutter back of tooth, and wherein z is that cutter tooth number, K are milling cutter relief grinding amounts; So just confirmed revised molded lines control point, the molded lines control point height h ' of rolling wheel set is the vertical range of molded lines control point to the highest control point straight line;
Step 3: with reference to the rolling wheel set molded lines before revising, be that straight line connects if promptly revise between preceding two the molded lines control points that will revise, these two revised molded lines control points remain straight line and connect; If revise between preceding two the molded lines control points that will revise is that camber line connects, and these two revised molded lines control points remain camber line and connect; Connect revised molded lines control point with straight line or circular arc, just obtained revised rolling wheel set molded lines.
The present invention is through practical application, and effect is splendid, has not only improved rolling wheel set correction precision, has also improved operating efficiency greatly.
Description of drawings
Fig. 1 is the sketch map that the present invention draws the rolling wheel set molded lines.
The specific embodiment
The specific embodiment one: combine Fig. 1 this embodiment to be described, following steps of the present invention:
Step 1: the rolling wheel set based on before revising goes out the rolling wheel set molded lines by 1: 1 scale; Draw the control point and the highest molded lines control point straight line 1 parallel of the rolling wheel set molded lines of the maximum gauge through rolling wheel set again, select out the molded lines control point X that the end points conduct of end points and the circular arc of the straight line in the rolling wheel set molded lines will be revised again with the centre of gyration line of rolling wheel set 2;
Step 2: select straight line and the molded lines control point X that respectively will revise as adjusting point, input cutter tooth number Z, milling cutter relief grinding amount K, milling cutter maximum radius R, said milling cutter employed instrument during for correction rolling wheel set molded lines; The molded lines control point height that calculates rolling wheel set wherein; R is the maximum exradius of milling cutter; H is that milling cutter radially cuts the form height degree; E is the eccentric throw of the approximate circular arc of the milling cutter back of tooth, and
Figure BDA0000105275060000022
wherein z is that cutter tooth number, K are milling cutter relief grinding amounts; So just confirmed revised molded lines control point X ', the molded lines control point height h ' of rolling wheel set is the vertical range of molded lines control point to the highest control point straight line;
Step 3: with reference to the rolling wheel set molded lines before revising, be that straight line connects if promptly revise between preceding two molded lines control point X that will revise, these two revised molded lines control point X ' remain straight line and connect; If revise between preceding two molded lines control point X that will revise is that camber line connects, and these two revised molded lines control point X ' remain camber line and connect; Connect revised molded lines control point X ' with straight line or circular arc, just obtained revised rolling wheel set molded lines.
Can use Grip exploitation, procedure of development, the Grip program is worked out under the UG platform, and unique developing instrument, compiling link process, program syntax and file format are arranged, and concrete development process is following:
(1) in the UG menu, selects Unigraphics Tool---UG Open Grip, eject NX Open Grip environmental interface.
(2) in UG Open Grip environmental interface, select Edit, create or open xz.grs file, just Grip source file with notepad; Select Compile that source file is compiled, generate the xz.gri file destination; Select Link to generate the xz.grx file again, this file is exactly the execute file that UG can discern, and can in the UG menu, click File---Execute UG/Open---Grip and call.
Program generates an xz.grx file through behind the compiling link, and selection File---Execute UG/Open---Grip from the UG menu chooses this xz.grx file just can performing a programme again, and this Grip program file is used to revise the rolling wheel set molded lines.
