Description

Предметом изобретени   вл етс  гидравлическа;; опра;м;а с жидким заполнителем, сжимаемым посредством полого рабочего плунжера, из органического стекла и с уплотнительными прокладками из гидропласта .;The subject matter of the invention is hydraulic ;; opra; m; and with liquid aggregate, compressible by means of a hollow working plunger, made of organic glass and with sealing gaskets made of hydroplast;

В известных конструкци х гидравлических оправок с жидким заполнителем уплотнение осуществл етс  кожаными, резиновыми или хлорвиниловы ,ми манжетами, которые не устран ют утечки из гицрополости,In the known designs of hydraulic mandrels with liquid aggregate, the seal is carried out with leather, rubber or vinyl chloride cuffs that do not eliminate leaks from the pericheral cavity,

В описыв-аемой конструкции уплотнение гидрополости оиравки с жидким занолнителем ооундествлено с помощью пробок и колец из гидропласта , расположенных в разъемных частей оправки в качестве уплотнительных прокладок, и нолого тонкостенного рабочего плунжера из органического стекла, заполненного гидронластом.In the design described, sealing a hydraulic cavity with a liquid sealer is determined with the help of plugs and rings made of hydroplast arranged in detachable parts of the mandrel as sealing gaskets, and a thin thin-walled working plunger made of plexiglass filled with hydronlast.

Высока  эластичность гидропласта и значительна  деформаци  стенок рабочего плунжера, плотно прилегающего к стенкам отверсти , поз1вол ют обеспечить надежное уплотнение гидрополости оправки.The high elasticity of the hydroplast and the significant deformation of the walls of the working plunger, which is tight to the hole, makes it possible to ensure a reliable seal of the hydraulic cavity of the mandrel.

На чертеже изображен продольный разрез гидравлической оправки с жидким заполнителем и уплотнителем из гпдротастимескпх поокладок.The drawing shows a longitudinal section of a hydraulic mandrel with a liquid filler and a sealant from gpdrostimeskshh pokladok.

Унлотиение гидрополости оправки, образованной корпусом / и втулкой 2, осуществлено с полющью зажатых в местах стыка уплотнительных колец 5 ,из гидропласта.The replacement of the hydraulic cavity of the mandrel formed by the body / and the sleeve 2, is carried out with a field clamped at the junction of the sealing rings 5, from the hydraulic layer.

Уплотнение рабочего плунжера 4 и регулирующего плунжера 5 выполнено посредством помещенных перед ними нробок 6 и ба из гидронласта .The sealing of the working plunger 4 and the regulating plunger 5 is carried out by means of nrobok 6 placed in front of them and a hydronast ba.

С целью надежного уплотнени  гидрополости со стороны рабочего плунжера и устранени  его нроворота при завинчивании нажимного винта 7, рабочий нлунжер выполнен в виде нолого тонкостенного цилиндра из органического стекла со стальным наконечником 8, взвимоаействующи;М нажимным винтом 7. Полость рабочего пл -нжера заполнена пробкой 9 из гидропласта и открыта со стороны гидронолостн оправки.In order to reliably seal the hydraulic cavity on the side of the working plunger and eliminate its level when screwing in the pressure screw 7, the operating stem is made in the form of a thin thin-walled cylinder made of organic glass with a steel tip 8, agglomerated; M by the pressure screw 7. from the hydroplast and is open from the side of the hydrololder mandrel.
