Изобретение относитс  к области механосборочных работ, в частности к устройствам дл  сборки и разборки прессовых соединеппн, преимущественно конусных.The invention relates to the field of mechanical assembly work, in particular to devices for assembling and disassembling press joints, mainly conical.

Известно гидравлическое устройство , содержащее силовой исполнительный механизм, соединенный трубопроводом через золотник с насосом, а также второй силовой исполнительный механизм, соединенный трубопроводом через золотник с насосом 1.Known hydraulic device containing a power actuator connected by pipeline through the valve to the pump, as well as a second actuator connected by pipeline through the valve to the pump 1.

Однако известное устройство не обеспечивает процесса сборки и разборки прессовых соединений, так как не предусматривает разницу давлений рабочей среды в рабочем исполнительном органе и при подаче ее в зону разъема соединени  деталей.However, the known device does not provide for the process of assembling and disassembling the press joints, since it does not provide for the difference in pressure of the working medium in the working actuator and when it is fed into the zone of the connector for connecting parts.

Известно также устройство дл  сборки и разборки прессовых соединений, содержащее гидродомкрат, соединенный трубопроводом через редукционные клапаны с гидроприводом , а также трубопровод дл  подачи рабочей среды в зону разъема соединени  2.It is also known a device for assembling and disassembling press joints, comprising a hydraulic jack connected by pipeline through hydraulic pressure reducing valves, as well as a pipeline for supplying working medium to the zone of the connector 2.

Однако известное устройство не обеспечивает требуемого качества сборки и разборки, так как дл  качественной сборки и разборки прессовых соединений необходимо выдерживать определенные соотнощени  давлени  рабочей среды, подаваемой в зону разъема соединени , к давлению среды, подаваемой в гидродомкрат.However, the known device does not provide the required quality of assembly and disassembly, since for high-quality assembly and disassembly of press joints, it is necessary to withstand certain ratios of the pressure of the working medium supplied to the joint area of the joint to the pressure of the medium supplied to the hydraulic jack.

Указанное устройство не обеспечивает посто нного выполнени  этого соотношени  дайлений , поэтому наблюдаютс  случаи выхода из стро  деталей прессового соединени  (задир сопр гаемых поверхностей, проворот деталей соединени  и т. п.).The said device does not ensure the constant fulfillment of this diving ratio, therefore there are cases of failure of parts of the press connection (scuffing of mating surfaces, turning of parts of the connection, etc.).

Целью изобретени   вл етс  повышение качества сборки и разборки за счет исключени  задиров сопр гаемых поверхностей (при сборке и разборке) соединений с прессовой посадкой путем подачи жидкости гидродомкрат после достижени  заданной величины давлени  в зоне разъема соединени . Указанна  цель достигаетс  тем, что устройство снабжено регулируемым золотником, соединенным с напорной полостью насоса, с рабочей полостью гидродомкрата и с зоной разъема сопр гаемых прессовой посадкой деталей, а редукционные клапаны установлены между золотником и гидроприводом.The aim of the invention is to improve the quality of assembly and disassembly by eliminating the scuffing of mating surfaces (during assembly and disassembly) of joints with press fit by supplying fluid to the hydraulic jack after reaching a predetermined pressure value in the area of the joint connector. This goal is achieved by the fact that the device is equipped with an adjustable spool connected to the pressure cavity of the pump, to the working cavity of the hydraulic jack and to the connector area of the parts matched by press fit, and pressure reducing valves are installed between the slide valve and the hydraulic actuator.

На чертеже схематично показано предлагаемое устройство.The drawing schematically shows the proposed device.

Устройство содержит гидропривод в виде плунжерного насоса 1 высокого давлени , соединенного трубопроводом через редукционные клапаны 2 и 3 с золотником 4, полости которого соответственно соединены с рабочей полостью гидродомкрата 5 и с зоной разъема соединени  деталей 6 и 7. Дл  установки величины давлени  открыThe device contains a hydraulic actuator in the form of a high-pressure plunger pump 1 connected by pipeline through pressure reducing valves 2 and 3 to the spool 4, the cavities of which are respectively connected to the working cavity of the hydraulic jack 5 and to the connector area of the connection parts 6 and 7. To set the pressure open
