The following description is made in detail by way of example with reference to the accompanying drawings.
FIG. 1 is a front view of a tool for machining a universal nut;
fig. 2 is a top view of fig. 1.
In the figure: 1-a knife handle; 1-1-bevel; 1-2-tool apron; 1-3-arc surface one; 1-4-an arc shoulder; 2-a cutter head; 2-1-cambered surface two; 2-2-knife edge; 2-3-straight edge.
Detailed Description
In the embodiment, referring to the attached drawings, the cutter for machining the universal nut comprises a cutter handle 1, wherein a cutter head 2 is welded at the left end of the cutter handle 1, and is characterized in that a first arc surface 1-3 is formed on the cutter head 2, a second arc surface 2-1 is formed below the cutter head 2, a straight cutting edge 2-3 is arranged at the lower end of the second arc surface 2-1, and a left end of the straight cutting edge 2-3 is provided with a bevel cutting edge 2-2; an inclined plane 1-1 is formed at the upper part of the left side of the cutter handle 1, a cutter holder 1-2 is formed between the lower end of the inclined plane 1-1 and the cutter head 2, and an arc-shaped shoulder 1-4 is arranged below the cutter holder 1-2.
The included angle between the inclined surface 1-1 and the horizontal line of the tool holder 1 is alpha 1, and alpha 1=60 degrees.
The included angle between the bevel edge 2-2 and the horizontal line of the cutter head 2 is alpha 2, and alpha 2=70 degrees.
The distance between the straight edge 2-3 and the horizontal line of the tool apron 1-2 is H, and H =15 mm.
The angles of the included angles alpha 1 and alpha 2 and the size of the angle H are determined according to the size requirement of the processed universal nut.
During machining, firstly, a tool shank 1 of a tool is fixed on a chuck at the driving shaft end of a machine tool, a universal nut to be machined is aligned and fixed on a workbench of the machine tool according to the position of a tool bit 2, and the machine tool can be started to machine after the universal nut is fixed.
