First claim

The invention claimed is:

1. A combined type angle head milling cutter for machining mounting faces of an axial bearing, comprising an angle head body, a lock nut, first slotted countersunk head screws, a first hexagon socket head cap screw, a first flat key, semicircle seal covers, first angular contact ball bearings, a cutter handle shaft lower adjusting pad, a cutter handle shaft, a cutter handle shaft upper adjusting pad, a bearing cover plate, a first bevel gear, a first spring washer, a second bevel gear, a bevel gear adjusting pad, an orientation shaft, cutter shaft inner-side seal covers, second hexagon socket head cap screws, a cutter shaft outer-side seal cover, a second slotted countersunk head screw, a small seal ring, a first shaft circlip, round nuts, flat washers, short cutter locating sleeves, long cutter locating sleeves, cutters, second flat keys, cutter adjusting pads, a cutter shaft end cover, a big rubber seal flat pad, a cylindrical gear, a second spring washer, a third flat key, an M10 hexagon thin nut, a transition cylindrical gear, a second shaft circlip, a left transition gear adjusting pad, a transition shaft end cover, a small rubber seal flat pad, a cylindrical drive gear, an M8 hexagon thin nut, a bearing retaining ring, a second angular contact ball bearing, a drive shaft, a drive gear adjusting pad, a right transition gear adjusting pad, a third angular contact ball bearing, a transition shaft, a transition shaft seal cover, an O-shaped rubber seal ring, a gear adjusting pad, a cutter shaft, a big seal ring, deep groove ball bearings and a rubber seal flat pad; characterized in that, eight cutters are installed on the cutter shaft, the cutters being set in a way that positions thereof are adjusted via the cutter adjusting pads, the short cutter locating sleeves and the long cutter locating sleeves, and the flat washers being placed on the outmost cutters and fixed by the round nuts; two ends of the cutter shaft being installed on the angle head body by the deep groove ball bearings, and the cutter shaft inner-side seal covers and the rubber seal flat pad being installed on two sides of the interior of the angle head body by the second hexagon socket head cap screws; the cutter shaft inner-side seal covers not only being set to position the deep groove ball bearings, but also stopping cutting fluid and dust from entering the interior of the angle head body via the big seal ring; the right side of the cutter shaft being sealed by the cutter shaft outer-side seal cover, the rubber seal flat pad and the small seal ring, the cylindrical gear being installed on the left side of the cutter shaft, the position of the cylindrical gear being adjusted via the gear adjusting pad, the second spring washer being installed and fixed by the M10 hexagon thin nut, the cutter shaft end cover and the big rubber seal flat pad being installed on the outer side of the angle head body, and thus the cutter shaft being sealed; the cutter handle shaft being butted with the spindle of a machine tool; the cutter handle shaft being installed on the angle head body via the pair of first angular contact ball bearings, and the position of the cutter handle shaft being adjusted via the cutter handle shaft upper adjusting pad; the first bevel gear being installed at the end part of the cutter handle shaft, the position of the first bevel gear being adjusted by the cutter handle shaft lower adjusting pad, and the first spring washer and the lock nut being used for fixing the first bevel gear for preventing loosening; the outer rings of the first angular contact ball bearings and the angle head body being fixed by the bearing cover plate, and the cutter handle shaft being sealed by two semicircle seal covers; the drive shaft being connected to the angle head body via the second angular contact ball bearing, and the position of the drive shaft being fixed by a shaft shoulder and the bearing retaining ring; the second bevel gear being installed on the right end of the drive shaft, and engaged with the first bevel gear for transferring power, and the position of the second bevel gear being adjusted by the bevel gear adjusting pad; the cylindrical drive gear being installed on the left end of the drive shaft, the position of the gear being adjusted by the drive gear adjusting pad, the gear being fixed by the M8 hexagon thin nut, and the spring washer being placed therebetween for preventing loosening; the transition shaft being connected to the angle head body via the third angular contact ball bearing, the transition cylindrical gear installed on the transition shaft being engaged with the cylindrical gear and the cylindrical drive gear, the position of the transition cylindrical gear being adjusted via the right transition gear adjusting pad, and the end part of the drive shaft being fixed by the second shaft circlip for preventing the drive shaft from axially moving; and the transition shaft end cover and the small rubber seal flat pad being installed on the outer side of the angle head body, the transition shaft seal cover and the O-shaped rubber seal ring being installed on the inner side of the angle head body, and the above four components being all used for sealing the transition shaft and preventing the entering of the cutting fluid.

2. The combined type angle head milling cutter for machining the mounting faces of the axial bearing according to claim 1 , wherein the cutter handle shaft has a tail which meets the ISO7:24 standard.
