As preferably, described main carriage bottom is provided with blowpit, and the folder mouth of discharging notch and clamping device is complementary, and is convenient to finished product and can skids off lathe successively.
As preferably, described main carriage is provided with some fastener, and recessing bit is connected with main carriage by fastener with interior flatcar cutter.Fastener can be clamp-screw or clamping bolt, and recessing bit and interior flatcar cutter can move on main carriage and locate, and makes it to regulate distance with workpiece by the numerical control case, thereby keeps stable dimensional accuracy.
For the mill new technology, described technology may further comprise the steps a kind of band clasp fluted shaft cover with car:
A. in feed well, add some axle sleeve semi-finished product;
B. main carriage moves, and the charging notch is aimed at clamping device, by the charging oil cylinder axle sleeve semi-finished product is pushed clamping device and clamping;
C. main carriage moves, and recessing bit location and car go out the axle sleeve annular groove;
D. main carriage moves, and interior flatcar cutter location and car go out the axle sleeve inner plane;
E. main carriage moves, and the discharging notch is aimed at clamping device, and clamping device unclamps, and the axle sleeve finished product is fallen into blowpit.
Main carriage can be made moving of any direction in the bed piece two dimensional surface, be convenient to the charging oil cylinder axle sleeve semi-finished product are pushed clamping device, and clamping device provides power by the Hydraulic Station on the lathe, realizes the automated exchanged cutter of building together by the PC programme-control.The numerical control case that lathe is provided with can be controlled each moving component sequence of movement and movement locus.Recessing bit and interior flatcar cutter adopt the superhard alloy lathe tool, and it is used for processing Hardened Steel Workpiece, replace the grinding of annular groove and inner plane, can obtain surface quality and the dimensional accuracy higher than grinding.
Therefore, the present invention has under car hardness HRC58～64 high rigidity prerequisites, merge cutting the annular groove operation different with grinding face twice, formed by clamping, turning automatically, guaranteed the requirement of axle sleeve bottom surface and draw-in groove, once finished turning apart from tolerance and surface roughness, the manufacturing procedure beat shortens, by using new hard driving skills art, guarantee stable machining accuracy, characteristics such as structure advanced person.
