Abstract

A hydraulic bushing (1) to receive and retain a machining tool, in which the cavity (2) to receive the machining tool is preferably provided with an inflexible bottom, the inner wall of the cavity is arranged to be radially flexible via a tubular space (10) inside the inner wall. The tubular space can extend beyond the length of the cavity and which space contains a pressure medium to be influenced by pressurising means (3, 4, 5) that preferably includes an axially displaceable unit and that suitably utilises a thread arrangement. The pressurising means are arranged in the shift part (6) of the bushing which is intended to secure the bushing to the holder part (8) and which transmits a rotary movement to the bushing and in that the displacement direction of the unit is parallel with the axis of the bushing and can be influenced externally.

Description

504 380 f'- 10 15 20 25 30 35 slag som kanalen ll enligt Figur 3. Kanalen 10 står i förbindelse med en tillförselkanal 9 som i sin tur står i förbindelse med ett tryckmediumutrymme_8. I tryckme- diumutrymmet finns en axiellt rörlig kropp 4 försedd med tätningsring och försedd med en ventilkula 3. Kroppen 4 är páverkbar av en andra kropp 5, som är försedd med en yttre gänga samverkande med en gänga anordnad i det hål, där den nämnda andra kroppen är anordnad. Genom att utsätta den andra kroppen 5 för skruvrörelse kan således det tryckmedium, som befinner sig i den rörformiga kanalen 10 tillförselkanalen 9 och tryckmediumutrymmet 8 påverkas så att hàlrummets vägg blir förskjutbar i radiell riktning. 504 380 f'- 10 15 20 25 30 35 35 as the channel 11 according to Figure 3. The channel 10 is connected to a supply channel 9 which in turn is connected to a pressure medium space_8. In the pressure medium space there is an axially movable body 4 provided with a sealing ring and provided with a valve ball 3. The body 4 is actuated by a second body 5, which is provided with an outer thread cooperating with a thread arranged in the hole where the said second the body is arranged. Thus, by subjecting the second body 5 to screw movement, the pressure medium present in the tubular channel 10, the supply channel 9 and the pressure medium space 8 can be actuated so that the wall of the cavity becomes displaceable in radial direction.

Den andra kroppen 5 påverkas rent bakifrån med hjälp av något lämpligt verktyg exempelvis en skruvnyckel eller någon annan sorts nyckel. Vid hänvisningsbeteckningen 8 anges del som kan tillföra bussningen l rotationsrörel- Se.The second body 5 is actuated from the rear by means of some suitable tool, for example a wrench or some other kind of key. The reference numeral 8 indicates a part which can supply the bushing in a rotational movement.
