(2) process after, stay the surplus of 0.15 mm to be used for hone.Clamp hone head handle (diameter is φ 11) with the variable-ratio electric hand drill thick, smart hone is carried out in the hole, improve the surface roughness in hole with the out-of-roundness sum of errors of repairing the bore hole generation.
The processing in (3) assembling of lining, φ 8 holes and the hone of lining endoporus.
1. lining is contained in and puts cooled with liquid nitrogen on the lining sleeve together into after about 5 minutes, put the good hole of boring again into, and rap sleeve lining is seated.
2. by former existing hole, body 980 sides, on lining, process φ 8 holes with drill bit.
3. use the smart hone lining of hone head endoporus, to remove overlap or the burr that bores the generation of φ 8 holes and to repair the slight deformation that the lining endoporus produces because of cold setting.
Because the aperture in this kind situation is little, hole depth is similar to blind hole again, and the operating space is narrow and small, adopts common process equipment and traditional processing technology can't guarantee crudy.Bore hole body 980 is long-pending little, in light weight in this project, mechanism is compact, part processing precision is high, fit clearance is little; Characteristics according to body 980 self, utilize two very a cup hole position by boring bar locating shaft 410 is set, made full use of the structure of original very cup hole and camshaft hole 990, both guaranteed the positioning accuracy of boring bar 400, can control process velocity and feed velocity easily again, thereby guarantee the quality of machining hole.
Embodiment 3.
A kind of Boring machine, other structures are identical with embodiment 2, and difference is: the size of this Boring machine is different with embodiment 2, and it is that diameter is that φ 43.9mm, hole depth are 20mm that the Boring machine in the present embodiment is applied to former very cup hole dimension.Adjusting relative dimensions as required can meet the demands, and repeats no more here.
At last, need to prove that the occasion that Boring machine is suitable for is not limited only to the occasion of embodiment 2 and embodiment 3, the hole of other size also is suitable for this Boring machine, as long as adjust relative dimensions according to concrete needs.
Should be noted that at last; above embodiment is only in order to illustrate technical scheme of the present invention but not limiting the scope of the invention; although the present invention has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the essence and the scope of technical solution of the present invention.
