Description
Technical field
The present invention relates to a kind of technical field of mechanical processing more particularly to deep hole machining accessory, processing technology and cylinder head
Oil leak hole processing technology.
Background technology
An important branch of the deep hole machining as mechanical processing at present, depth drill is even more the important composition of deep hole machining,
It is higher and higher to its machining accuracy and stability requirement, but in the processing of intersection hole system, usually will appear short-bore and deep hole phase
The case where logical and axis antarafacial of holes, on the basis of short-bore is processed when deep hole processing, the processing of deep hole works as depth frequently with drill gun
When the major diameter in hole is bigger, due to there is certain eccentricity between short-bore and deep hole, if directly on the basis that short-bore machines
Upper deep hole processing, due to the unilateral stress at the position of short-bore, drill bit can not be positioned in center, easy sideslip, error accumulation,
It can lead to that workpiece is scrapped and cutter breaks.
And in cylinder head, the position relationship of fuel feed hole and oil leak hole is intersection hole mentioned above, is contained in cylinder head
Multiple fuel feed holes are communicated with oil leak hole between multiple fuel feed holes, and the axis antarafacial of fuel feed hole and oil leak hole, and eccentricity is more than
The aperture of fuel feed hole 1/2 equally exists the unilateral stress of oil inlet hole location, drill bit is in centre bit if directly cutting oil leak hole
To set can not position, and lead to that cylinder head is scrapped and cutter breaks.Especially：Occur (first processing short-bore, post-processing across process
Deep hole) processing workpiece, or must first machined short-bore for some reason, the case where post-processing deep hole, current process is also
Clearly not effective countermeasure.
