Description

(54) СПОСОБ ПРАВКИ ДЕТАЛЕЙ(54) METHOD FOR EDITING PARTS

Изобретение относитс  к способам пра:В,ки деталей.The invention relates to methods for p: B, ki parts.

Известен способ правки деталей, преимущест1ве«но коленчатых залав, заключающийс  в том, что деталь за1кре1пл ют не менее чем в д-вух точках, а затем двформи;руют.There is a known method of straightening parts, moreover, advantageously of crankshafts, which consists in the fact that the detail is recorded in at least two points and then in two shapes.

С целью повышени  производительности предложен способ, по которому дефор гиро(вание осуществл ют путем знакопеременного поперечного изгиба искривленного участка детали 1при вращении ее в плоскости, перпендикул рной продольной оси детали, кроме того, дл  обеспечени  правки деталей iC различной жесткостью величину изгиба Л1е1н ют иронорционально жесткости детали :в плоскости изгиба .In order to increase productivity, a method is proposed in which the deformation is carried out by alternating transverse bending of the curved section of the part 1 while rotating it in a plane perpendicular to the longitudinal axis of the part, moreover, to ensure that parts iC are modified with different rigidity, the amount of bending Le1e ironsally stiff Details: in the plane of bending.

Изобретение по сн етс  чертежом, где на фиг. 1 показана схема закреплени  детали; «а фИг. 2 - вид по стрелке А на фиг. 1.The invention is illustrated in the drawing, where in FIG. Figure 1 shows the detail fastening scheme; “A FIG. 2 is a view along arrow A in FIG. one.

Рассмотрим .пример правки z-образного кроиштейна, 1выполнен ного из i6pyca пр моугольного сечени . Кронштейн / закреплен неподвижными жесткими зaxJвaтaми 2 и имеет отклонение переднего торца 3 с центром 4 торца от проектного .положени  5 торца с центром 3 точке 6. Подэиж1ными за.хватами 7 кон-ец детали 1 перемещаетс  таким образом, чтобы контур торца 3 и центр его 4 оказались сов.мещенны1ми с проектным полажением 5Consider an example of editing a z-shaped croisstein made from i6pyca of a rectangular section. The bracket / is fixed with fixed rigid joints 2 and has a deviation of the front end 3 with the center 4 ends from the design position 5 of the end with the center 3 point 6. The bottom end hooks 7 end of the part 1 are moved so that the contour of the end 3 and its center 4 turned out to be combined with the project position 5

этого торца и положением центра торца в точке 6.this end and the position of the center of the end at point 6.

При этом пере мещении деталь / в зависимости от веЛИчины деформации и жесткостиWhen moving this part / depending on the magnitude of the deformation and stiffness

детали может претерпеть как упругую, так и пла1стическую деформа ции. Если с захватов сн ть усили , удерживающие конец детали в проектноМ положении 5, то этот конец детали члн :вер1нетс  в исходное положение, или займет какое-то промежуточное .положение.parts may undergo both elastic and plastic deformations. If the force is removed from the grippers, which holds the end of the part in design position 5, then this end of the part is returned to its original position, or it will take some intermediate position.

. Дл  того чтобы добитьс  щроектного положени  5 торца 3 детали и после сн ти  уоиЛИЙ с за.хватов 7, необходимо переместить центр.4 торца 3 через точку 6 проектного ттоложени  iB точку 8 (фиг. 2).. In order to achieve the design position 5 of the end 3 parts and after removing the tool from catch 7, it is necessary to move the center 4 of the end 3 through point 6 of the design position iB point 8 (Fig. 2).

Отклон  , конец детали в любом направлении от .проектного .положени  1на велИЧИну упругой деформации, гарантируют ее возврат в исхадное .положение. Бели же центром (илиThe deviation, the end of the part in any direction from the design position 1 to the value of elastic deformation, guarantee its return to the original position. Beli center (or

любой другой точкой торца описать вокруг ее проектного положени  кривую, представл ющую собой пол рную эпюру предельной упругой дефорМацки детали, то в случае выполнени  этой операции над деталью с правильнымdescribe a curve, representing a polar diagram of the ultimate elastic deformation of a part, around its design position with any other end point, then in the case of performing this operation on a part with the correct

положением торца она ншкаких пластических деформаций не испытает.the position of the end face will not experience nshkak plastic deformations.

Величину вынужденной деформации снимают ил.авньрм уменьщением радиуса спиралеобразной кривой О-6, которую описывает торец детали.The magnitude of the forced deformation is removed by the illusion by decreasing the radius of the spiral O-6, which is described by the end of the part.
