Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
As shown in Figures 1 to 4, this is used for the compound tool of stepped hole and inner annular slot machining, comprise handle of a knife 1, cutter hub 2, shaping blades, wherein, handle of a knife 1 is positioned at cutter hub 2 one end, and shaping blades is positioned at cutter hub 2 other end, be connected by flange arrangement between handle of a knife 1 with cutter hub 2, between position can finely tune, handle of a knife 1 is connected with machine tool chief axis, is fixed on machining tool by cutter.
Shaping blades comprises stepped hole forming reamer and Slot shaping cutter, and Slot shaping cutter is fixed on cutter hub outermost end, and stepped hole forming reamer 3 is fixed on cutter hub 2 and is positioned at inside Slot shaping cutter 4.
Cutter hub 2 is divided into inner segment and outer section, and the external diameter of cutter hub inner segment is greater than the external diameter of the outer section of cutter hub, and stepped hole forming reamer 3 is fixed on inner segment, and Slot shaping cutter 4 is fixed on outer section, and the external diameter of stepped hole forming reamer 3 is greater than the external diameter of Slot shaping cutter 4.
The external diameter of Slot shaping cutter 4 is less than the internal diameter in the hole of workpiece to be processed 5, and be convenient to the inside, hole that Slot shaping cutter 4 enters workpiece to be processed and carry out cannelure processing, wherein, Slot shaping cutter is Slot shaping milling cutter.
