Abstract

Изобретение относитс к механосборочному производству и может быть использовано при сборке прессовых соединений деталей. Цель изобретени - расширение технологических возможностей и повышение производительности стендов дл сборки прессовых соединений. Стенд содержит установленные вдоль оси станины 5 две неподвижные стойки 4 и 21 с силовыми цилиндрами /Ц/ 3 и 22, неподвижный корпус 7 и размещенный в нем стакан (С) 1, жестко закрепленный на штоке 2. Внутри С 1 размещены пружина 11 и центрирующа оправка 13. Центрирующий элемент может быть выполнен в виде продольного выступа, закрепленного на оправке 13 с возможностью размещени в пазу С1. Торец центрирующей оправки 13 выполн етс по меньшей мере с двум конусными центрирующими элементами 20. После подготовительной установки и ориентировки собираемых деталей в корпусе редуктора 26 включением Ц 3 и 22, движением оправки 24 в сторону корпуса редуктора 26 перемещают вал-шестерню 30 в сторону С 1, и, преодолева усилие пружины 11, осуществл ют сборку вала с шестерней, обеспечива их сопр жение по шпоночному соединению. 2 з.п. ф-лы, 6 ил.The invention relates to a mechanical assembly production and can be used in the assembly of press joints of parts. The purpose of the invention is to expand the technological capabilities and increase the productivity of stands for the assembly of press joints. The stand contains two fixed racks 4 and 21 with power cylinders / C / 3 and 22 mounted along the axis of the frame 5, the fixed body 7 and the cup (C) 1 placed in it, rigidly mounted on the rod 2. Inside C 1 there is a spring 11 and centering the mandrel 13. The centering element can be made in the form of a longitudinal protrusion fixed on the mandrel 13 with the possibility of placement in the groove C1. The end of the centering mandrel 13 is performed with at least two conical centering elements 20. After the preparatory installation and orientation of the assembled parts in the gearbox housing 26 by turning on C 3 and 22, by moving the mandrel 24 to the gearbox housing 26 move the gear shaft 30 to the side C 1 and, overcoming the force of the spring 11, carry out the assembly of the shaft with the gear, ensuring their mating by the keyed connection. 2 hp f-ly, 6 ill.

Claims

1. A stand for assembling press joints of parts of the shaft-sleeve type, comprising installed along the longitudinal axis of the stan-

5 there are two stationary racks with power cylinders with rods, at least one of which has a centering element of connected parts, characterized in that, in order to expand technological capabilities and increase θ productivity, it is equipped with a fixed case mounted on the bed and a glass rigidly connected to the rod of the power cylinder with a centering element and placed in the cavity of the stationary housing with the possibility of translational movement relative to it along the axis of the rod, and also placed bubbled into the inner cavity of nozzle elastic member and a central mandrel mounted for limited movement of postupatelno'0.

2. Stand by π. 1, characterized in that the centering element for the details of the sleeve type is made in the form of a longitudinal • 5 protrusion attached to the end of the centering mandrel, and a groove is made on the inner surface of the glass to accommodate the said longitudinal protrusion.

3. Stand by π. 1, characterized in that the end face of the centering mandrel is made

Yu with at least two conical centering elements.
