Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figures 1 to 4, axle housing mesopore processing technology of the present invention, comprises the following steps:
A, heavy boring: adopt boring cutter heavy boring mesopore 11; Heavy boring mesopore pore size, ensures the surplus of right boring;
B, chamfering: adopt the aperture of rose reamer to reinforcing ring side 12 and back cover side 13 to carry out chamfering;
C, anti-right boring: adopt reverse boring cutter right boring mesopore 11, anti-thorax cutter is moved to reinforcing ring side 12 by back cover side 13.
As shown in Figures 1 to 4, mesopore 11 is opened in the through hole on axle housing middle piece 1, and on axle housing middle piece 1, one end of mesopore 11 is provided with reinforcing ring, and the other end of mesopore 11 is provided with back of the body lid 2; For convenience, the side that reinforcing ring is close to mesopore 11 is called reinforcing ring inner face, the another side relative with reinforcing ring inner face is called reinforcing ring outer face 14.
