Description
Technical field
The present invention relates to center-rotary joint manufacturing technology fields, and in particular to a kind of center revolution based on deep hole positioning
Connector cross drilling attachment and technique.
Background technique
Center-rotary joint component is the hydraulic system of the machinery such as excavator, crane, land leveller, tower crane, rotary drilling rig
In critical component, effect is the fixed fluid pressure line with rotating part in the entire hydraulic system of connection, makes system hydraulic tube
Upper and lower two part in road has 360 degree of opposite rotary motion without interfering.
Body element in center-rotary joint component is the center-rotary joint body shaft as spindle nose, above along axis
To deep hole is offered, the transverse holes for carrying out lateral centering with the deep hole and connecting laterally are offered.
For the center-rotary joint body shaft of large-scale over-long, deep hole is relatively thin and deep, it is therefore desirable to using overlength drill bit into
Row drilling, deep hole will also bore transverse holes after being drilled, it is required that transverse holes and deep hole have good accuracy of alignment, be returned with meeting center
The performance requirement of adapter component.But it is rigidly poor when due to deep hole machining, and the tune of part its axial position in clamping
Whole precision has certain error, certain axial deflection can occur after leading to deep hole drilling, its about deep skewed error of deep hole is bigger.
After the skewed error of this deep hole will lead to subsequent transverse holes drilling processing, relative dislocation occurs between transverse holes and deep hole,
That is transverse holes and deep hole is unable to centering, thus reduces the quality of product, and when serious dislocation also results in scrapping for product.
Since there are the above-mentioned skewed errors of deep hole, pressed from both sides using conventional boring method in the prior art and boring positioning
Has and cannot achieve the good centering of transverse holes and deep hole.
