DEVICE FOR MANDRELLING OF SMALL DIAMETER HOLES |
摘要 |
FIELD: technological processes. ^ SUBSTANCE: invention is related to the field of mechanical processing of holes, namely, to devices for mandrelling of small diameter holes. Device contains casing with slot for installation of processed part. Guide bushing made of elastic anti-friction material is immovably fixed in casing. Mandrel and mandrel drive pusher are installed in the hole of guide bushing. Support bushing for part installation is installed coaxially relative to the guide bushing. Support bushing is installed in the casing with the possibility of axial movement. Support bushing lifting is provided by means of fork. Mandrel return pusher is installed in the hole of support bushing. ^ EFFECT: increase of hole mandrelling device operation convenience and expansion of its technological resources. ^ 3 dwg |
