(5) НАПРАВЛЯЮЩАЯ ОПРАВКА К СТАНКУ ДЛЯ УКЛАДКИ КАТУШЕК 3 ПАЗЫ СТАТОРА(5) GUIDE FRAME TO THE MACHINE FOR LAYING COILS 3 STATOR SLOTS

II

Изобретение относитс к электромашиностроению и может быть использовано при изготовлении статоров электрических машин, например дл укладки катушечных групп в пазы статора .The invention relates to electrical engineering and can be used in the manufacture of electric machine stators, for example, for laying coil groups into stator slots.

Известна оправка к станку дл вт гивани и заклинивани обмоток в пазах статора, предназначенна дл направлени статора при его насадке .на штыревую оправку и содержаща руко тку и насаженную на нее пробку, выполненную в виде звезды с пр мыми лепестками Cl.The known mandrel to the machine for retraction and wedging of the windings in the stator grooves is intended to guide the stator with its attachment to the pin mandrel and containing a handle and a star-shaped plug mounted on it with straight petals Cl.

Однако эта оправка не обеспечивает раскрыти пазовых коробов статора и их фиксации в пазовых крышках штыревой оправки при сборке статора с катушками, что снижает надежность сборки статора.However, this mandrel does not provide opening of the slot boxes of the stator and their fixation in the slot covers of the pin mandrel when assembling the stator with the coils, which reduces the reliability of the assembly of the stator.

Цель изобретени - повышение надежности.The purpose of the invention is to increase reliability.

Указанна цель достигаетс тем, что пробка выполнена в виде двухступенчатого цилиндра, на наружной поверхности большего диаметра которого установлена шпонка, а на поверхности цилиндра меньшего диаметра выполнены продольные Т-образные пазы, каждый из направл ющих элементов выполнен в виде двутавра с полкой трапецеидальной формы, обращенной боль- . шим основанием трапеции к торцу цилиндра малого д иаметра, а друга This goal is achieved by the fact that the cork is made in the form of a two-stage cylinder, the key is installed on the outer surface of a larger diameter, and longitudinal T-shaped grooves are made on the surface of the cylinder of smaller diameter, each of the guiding elements is made in the form of an I-beam with a trapezoidal shelf facing big We sew the base of the trapezoid to the end of the cylinder of a small diameter, and a friend

10 полка установлена в пазу, при этом количество направл ющих элементов соответствует количеству пазов статора .The 10th shelf is installed in a groove, wherein the number of guiding elements corresponds to the number of stator slots.

На фиг. I показана предлагаема FIG. I shows the proposed

15 направл юща оправка, продольный разрез; на фиг. 2 - сечение А-А на фиг. 1; на фиг, 3 - сечение Б-Б на фиг. 1.15 guide mandrel, longitudinal section; in fig. 2 is a section A-A in FIG. one; FIG. 3 is a section BB in FIG. one.

Claims

X for stacking the coils into the grooves of the stator contains a handle 1, on which a plug 2 is tightly fitted, made in the form of a two-stage cylinder. On the outer surface of a cylinder of a larger diameter, which corresponds to the diameter formed by the inner surfaces of the pins 3 of the pin mandrel (not shown), is placed on the key to ensure that the slots of the stereo 5 coincide with the slots formed by the pins of the 3 pin mandrel. The small diameter of the two-stage cylinder of the plug 2 is made with longitudinal external grooves in which guide elements (inserts) 6 are installed, made in cross-section in the form of an I-beam. The outer shelf of the I-beam is designed to open the slotted boxes 7 of the stator 5, and the inner shelf to install the guide elements (inserts) 6 into the grooves of the plug

2. The outer shelf of the insert 6 is made in the form of a trapezoid, the base width of which is equal to the distance between the grooves 8 of the slotted covers 9 of the pin mandrel. The stopper 2 is fixed on the lower part of the handle 1 with the help of the nut 10. The guide mandrel operates as follows. After winding the coils and transferring them into the slots of the pin mandrel, the assembled guide mandrel does not fit and then the stator is put on. The inserts 6 of the guide mandrel fit into the slots between the pins 3 of the pin mandrels, while the outer trapezoidal shelves of the inserts 6 fit into the slots of the stator 5 and push apart the walls of the slot boxes, thereby causing the ends of the boxes to sink into the grooves 8 of the slot 4 covers 9 and are held there while the coils are being drawn into the stator slots. The use of the proposed guide mandrel improves assembly reliability by fully opening the slot boxes at. pulling coils into stator slots. The invention of the guide mandrel to the machine for placing the coils in the stator grooves, containing a handle and a stopper with guiding elements, is one that, in order to increase reliability, the stopper is made in the form of a two-stage cylinder on the outer surface of a larger the diameter of which is set a key, and longitudinal T-shaped grooves are made on the surface of a cylinder of smaller diameter, each of the guiding elements is made in the form of an I-beam with a trapezoidal shelf facing a large base of tradition The diameter of the cylinder is small, while the other shelf is installed in a groove, and the number of guide elements corresponds to the number of stator slots.
