Станок для сборки поворотных кругов содержит корпус 1, планшайбу 2, электродвигатель 3, дозатор 4 с электроприводом 5 и фиксаторы 6 наружной обоймы круга от проворота.The machine for assembling turntables contains a housing 1, a faceplate 2, an electric motor 3, a dispenser 4 with an electric drive 5 and latches 6 of the outer ring cage from rotation.

Планшайба 2 установлена в подшипниках 7 и 8 на валу 9 в корпусе 10, который установлен на станине 1. Вал 9 через шпонку 11 соединен с валом 12 червячного редуктора 13 и установлен .в подшипниках 14 и 15. Корпус червячногоThe washer 2 is installed in bearings 7 and 8 on the shaft 9 in the housing 10, which is mounted on the bed 1. The shaft 9 is connected via a key 11 to the shaft 12 of the worm gearbox 13 and is installed in bearings 14 and 15. The worm housing

1315 4 цевая часть 60 которого установлена в горизонтальном пазу 61, выполненном в торцовой части 62 втулки 55. На корпусе 1 станка установлен блок управлэ— $ ния 63.1315 4, the main part 60 of which is installed in a horizontal groove 61, made in the end part 62 of the sleeve 55. A control unit 63 is installed on the machine body 1.

Станок для сборки поворотных кругов работает следующим образом.Machine for assembling turntables works as follows.

Наружная обойма поворотного круга отверстиями, выполненными на крепежном 10 фланце, надевается на выступы 64 фиксаторов 6 и тем самым удерживается в вертикальном положении. В наружную обойму вставляется внутренняя обойма поворотного круга, при этом ползуны 28 зажима распо15 лагаются напротив отверстий в обойме.The outer casing of the turntable with holes made on the mounting 10 of the flange, is put on the protrusions 64 of the latches 6 and thereby is held in a vertical position. The inner race of the turntable is inserted into the outer race, while the slide sliders 28 are located opposite the holes in the race.

Затем включением силового цилиндра 17 через шток 19 коническая втулка 23 взаимодействует через выступы 26 с пазами 27 ползунов 28, осуществляя зажим 20 внутренней обоймы поворотного круга. Та_ким образом наружная и внутренняя обой’ ’ мы готовы для загрузки в их беговые рожки элементов качения, при этом загрузочное отверстие, выполненное в на— 25 ружной обойме поворотного круга и неподвижного в радиальном направлении за счет фиксаторов 6, находистя в верхнем положении.Then, by turning on the power cylinder 17 through the rod 19, the conical sleeve 23 interacts through the protrusions 26 with the slots 27 of the sliders 28, thereby clamping 20 the inner ring of the turntable. In this way, the outer and inner wallpaper ’’ we are ready to load rolling elements into their running horns, with a loading hole made in the outer sleeve of the turntable and stationary in the radial direction due to the latches 6, located in the upper position.

Включается механизм 49 поворота сопла 48 в рабочее положение,*автоматически включается электродвигатель 3 привода планшайбы 2 и привод 5 дозатора 4 подачи шариков 37.The mechanism 49 for turning the nozzle 48 to the operating position is turned on, * the electric motor 3 of the drive of the faceplate 2 and the drive 5 of the dispenser 4 of the ball feed 37 automatically turn on.

Как только произойдет загрузка расчетного количества шариков 37 в собираемый узел, кулачок, установленный на выходном валу дозатора 47, взаимодействуя с конечным выключателем, отключит дозатор 4 подачи шариков 37 и привод 3 планшайбы 2.As soon as the estimated number of balls 37 is loaded into the assembly, the cam mounted on the output shaft of the dispenser 47, interacting with the limit switch, will turn off the dispenser 4 for supplying the balls 37 and the drive 3 of the faceplate 2.

При отключенном дозаторе 4 подачи шариков 37, шарики, находящиеся в сопле 48 при его повороте в нерабочее положение, удерживаются от высыпания пружинным кольцом 53.When the dispenser 4 for supplying balls 37, the balls located in the nozzle 48 when it is turned into an idle position are kept from spilling out by the spring ring 53.

Использование устройства в народном хозяйстве позволяет не только повысить производительность труда и качество сборки изделий типа поворотных кругов, но создает возможность автоматизировать процесс.The use of the device in the national economy allows not only to increase labor productivity and assembly quality of products such as turntables, but also creates the ability to automate the process.
