Abstract

Изобретение относитс  к машиностроению, в частности к устройствам дл  уравновешивани  вертикально-подвижных органов металлорежущих станков. Цель изобретени  - повышение экономичности работы устройства за счет уменьшени  гидравлических потерь на дросселирование рабочей жидкости. Так, при подъеме подвижного органа 2 в штоковой полости гидроцилиндра 1 уравновешивани  поддерживаетс  давление слива, а в поршневой - давление уравновешивани . При опускании подвижного органа 2 в штоковой полости гидроцилиндра 1 устанавливаетс  давление посредством св зи этой полости с помощью гидрораспределител  8 с редуцированным давлением подпитки гидроаккумул тора 3. 2 з.п. ф-лы, 3 ил.The invention relates to mechanical engineering, in particular to devices for balancing the vertically movable parts of machine tools. The purpose of the invention is to increase the efficiency of the device by reducing the hydraulic losses on the throttling of the working fluid. Thus, when the movable member 2 is raised, the pressure of the balance cylinder 1 of the balancing cylinder 1 is maintained, and the pressure of the balance in the piston cavity. When lowering the rolling element 2 in the rod cavity of the hydraulic cylinder 1, pressure is established by coupling this cavity with the help of the hydraulic distributor 8 with the reduced pressure of the hydroaccumulator 3. 3. C. f-ly, 3 ill.

Формула изобретенияClaim 1. Устройство уравновешивания вертикально-подвижного органа металлорежущего станка, содержащее гидроцилиндр уравновешивания, шток которого предназначен для соединения с подвижным органом, а поршневая полость связана гидролинией с гидроаккумулятором, имеющим систему питания, редукционный и переливной клапаны, отличающееся тем, что, с целью повышения надежности в работе за счет уменьшения гидравлических потерь на дросселирование рабочей жидкости, устройство снабжено гид равлическим узлом нагружения подвижного органа дополнительным усилием, при этом редукционный и переливной клапаны установлены в гидролинию связи аккумулятора с гидроцилиндром уравновешивания параллельно и навстречу друг другу.1. The balancing device of a vertically movable body of a metal cutting machine, containing a balancing hydraulic cylinder, the rod of which is designed to connect to a movable body, and the piston cavity is connected by a hydraulic line to a hydraulic accumulator having a power system, pressure reducing and overflow valves, characterized in that, in order to increase reliability in operation due to the reduction of hydraulic losses due to throttling of the working fluid, the device is equipped with an additional hydraulic unit for loading the moving body perpetuate violence, thus reducing and overflow valves are set to the hose connection with the accumulator cylinder and the equilibration parallel towards each other. 2. Устройство по π. 1, отличающееся тем, что узел нагружения выполнен в виде двухпозиционного распределителя, связанного с одной стороны с системой питания гидроаккумулятора и сливом, а с другой — со штоковой полостью гидроцилиндра уравновешивания.2. The device according to π. 1, characterized in that the loading unit is made in the form of a two-position distributor connected on the one hand to the accumulator supply system and drain, and on the other, to the rod cavity of the balancing hydraulic cylinder. 3. Устройство по π. 1, отличающееся тем, что узел нагружения при подъеме подвижного органа выполнен в виде установленного параллельно гидроцилиндру уравновешивания дополнительного гидроцилиндра, поршневой полостью связанного через двухпозиционный распределитель либо с системой питания гидроаккумулятора, либо со сливом.3. The device according to π. 1, characterized in that the load node when lifting the movable member is made in the form of balancing an additional hydraulic cylinder mounted parallel to the hydraulic cylinder, the piston cavity connected via a two-position distributor either to the accumulator power supply system or to the drain.
