Two-station mechanism for machining main bearing seat, oil groove and tile groove

一种二工位加工主轴承座以及油槽、瓦槽的机构

Abstract

本实用新型公开一种二工位加工主轴承座以及油槽、瓦槽的机构,在铣头上水平设置有工位I和工位II,其中,工位I的刀杆上装有八把锒齿两面刃铣刀和五把槽铣刀;工位II的刀杆上装有五把槽铣刀;刀杆上设置有调整刀具轴向位置的隔套。本实用新型通过对铣刀的特殊设置,实现了一次性完成对四缸柴油机机体主轴承座八侧面以及油槽、瓦槽的加工,有效降低了加工成本,且加工精度高、工效高。
The utility model discloses a two-station mechanism for machining main bearing seat, oil grooves and tile grooves. A milling head is horizontally provided with a station I and a station II, wherein, a cutter holder of the station I is provided with eight inserted-tooth two-edge cutters and five groove milling cutters. The cutter holder of the station II is provided with five groove milling cutters. Each cutter holder is provided with a sleeve gasket which adjusts an axial position of the cutter. Through special setting to the milling cutter, the two-station mechanism realizes one-time machining to eight side surfaces of a main bearing seat of a four-cylinder diesel engine, oil grooves and tile grooves. Furthermore the two-station mechanism has the following advantages: effectively reduced machining cost, high machining precision and high operation efficiency.
