Abstract
The present invention relates to a grinding point scraping method for a fixed binding surface in position. When a fixed binding surface reaches 5 to 7 points per sq inch by conventional scraping, the fixing binding surface is fastened. Thus, a machine tool is in an operating state under the action of a vibrator or by switching on a traction motor, the fixing binding surface can generate vibrating friction, few presented hard contacting points can be observed on each sq inch, scraping is then carried out, the hard contacting points are increased by repeating 5 to 6 times, and the number of the hard points on each sq inch can not change. The accuracy of the fixed binding surface can be improved according to a formula, and the accuracy of the present invention is higher than sliding grinding point method.
Description
The present invention relates to the scraping method on plane.Particularly a kind of scraping method that improves the fixed combinating surface contact stiffness.
At present, in existing lathe assembling process, no matter be slidingly connected all to adopt to slide before face or the fixed combinating surface scraping and grind a method, a this method of grinding is fit to for the face of being slidingly connected, it is constant to contact the constant quantity of hard spot when making with use, can guarantee that contact stiffness is stable, but for fixedly contact-making surface is just improper, the contact hard spot is a lot of when grinding though slide, owing to there is meso-and mega-relief, have only the only a few hard spot to participate in contact during fixing the contact, the lathe stiffness is low to making, patent 89109019.3 checkered scrapers for example, under the drive of power finished piece surface is carried out the micro cutting processing of spaced discontinuities outside, makes piece surface form the convex-concave spot of forming by certain rule and pattern, from microcosmic piece surface is uneven and height alternate, make piece surface store oil, strengthen static oil film thickness, can improve the bearing capacity of part, but can not obviously prolong lathe fixedly contact-making surface accuracy life and raising stiffness.
The purpose of this invention is to provide a kind ofly at lathe or other scraping method for fixed binding surface in position of grinding point, contact stiffness is improved, machine tool accuracy is stable, prolong accuracy life.
The present invention includes following steps:
When (A) earlier being worked into every heart 5-7 point, adopt a facing that grinds in place to continue processing with conventional facing, fixed combinating surface is fastening, under the vibrator effect, perhaps start dragging motor and make lathe be in rotary state, then vibrate and rub in the fixed combinating surface appearance.
(B) checking by blueing check can be found minority contact hard spot, and the scraping hard spot grinds a little more then, scraping again, and so circulation is gone down, and the hard spot that grinds an appearance this moment all occurs after assembling.
(C) check juxtaposition metamorphose, after the faying face that scraping is finished is fastening, on forcing press, pressurize that recording juxtaposition metamorphose by 4 amesdials is zero.
The present invention slides and grinds a method stiffness height, and particularly the stationary plane that can't improve contact stiffness with the method for grinding of sliding is more suitable for.
The present invention is applied in the scraping that requires the high mating surface of stiffness in the lathe manufacturing, and when particularly grinding the stiffness that a method do not guarantee mating surface with sliding, employing this law is better., can detect by an unaided eye after conventional scraping at fixed combinating surface, every heart reaches the 5-7 point, fixed combinating surface is fastening, under the effect of vibrator, perhaps make lathe in running order, after the vibration friction with connecting dragging motor, minority contact hard spot displays, again according to the hard spot that manifests, repeatedly scraping several times, precision is improved, grind a contact stiffness of method processing than adopt sliding and improve and stable accuracy, according to formula: contact stiffness
Average pressure, C-coefficient between the P-contact-making surface, contact point increases, and the C value reduces, and contact stiffness increases the increase of fixed combinating surface contact hard spot, and will be directed at the fixed combinating surface contact stiffness increases.
Claims (1)
1, a kind of scraping method for fixed binding surface in position of grinding point comprises the steps:
When (A) earlier being worked into every heart 5-7 point, adopt a facing that grinds in place to continue processing with conventional facing, fixed combinating surface is fastening, under the vibrator effect, perhaps start dragging motor and make lathe be in rotary state, then vibrate and rub in the fixed combinating surface appearance.
(B) checking by blueing check can be found minority contact hard spot, and the scraping hard spot grinds a little more then, scraping again, and so circulation is gone down, and the hard spot that grinds an appearance this moment all occurs after assembling.
(C) check juxtaposition metamorphose, after the faying face that scraping is finished is fastening, on forcing press, pressurize that recording juxtaposition metamorphose by 4 amesdials is zero.
