Abstract
The invention relates to a machining method of a slant-hole machine. The machining method comprises the following steps: (1) machining an end surface (2) which is vertical to the feeding direction of a cutter on a vertical end surface (1), and eliminating a part (3) in a semi-cutting state between a drill stem and the vertical end surface; (2) in a drilling-out position of a drill hole, manufacturing a compensating material (5) on an circular-arc surface (4) attached with an inner hole by using machining prepared materials, and fixing the compensating material (5) at a hole machining position with parts; (3) driving the cutter for feed machining, feeding to the position of the compensating material (5) and then retracting; and (4) finally cutting the compensating material (5) off, polishing the end surface (2) and finishing the whole machining process. In the method, as the method that the drill stem is in full contact with the parts during the whole machining process, the semi-cutting state can not be generated, thereby ensuring the machining precision and finishing the machining process. The machining method is simple and practical, ensures the slant-hole machining requirements and is a convenient and practical machining method of the slant-hole machine.
Description
Technical field
The present invention is a kind of machining method of slant-hole machine, belongs to the innovative technology of machining method of slant-hole machine.
Background technology
Boats and ships repair, make the machined operation that constantly has part in the process, maximum is boring and bore hole.Generally all be the processing straight hole, the less processing problems that runs into inclined hole.The process that the processing of straight hole is existing ripe, cutter and part are in full contact condition always, however the processing of inclined hole, because the problem at inclination angle, having cutter and part is half state of contact when feed and the situation that gets out; Half state of contact makes drilling rod produce torsion, causes bit freezing or drill rod breaking easily, and makes the axis runout of processing, does not satisfy the precision of processing.
Such as, the processing difficulties of the stern tube shaft pipe of the 76000t bulk freighter that company builds is at the stern tube shaft tube axis direction deep hole of two 1 ° of angles and the deep hole (length that runs through the stern tube shaft pipe) of two 8 ° of angles to be arranged.In view of big (long nearly 1 meter of workpiece appearance and size, width is above 1 meter), because part is long,, pierce from vertical end face so drilling rod can design longlyer, drilling rod just part cuts stressed, when arc surface got out, length 100mm was nearly cut in the hemisection of this moment, and part cutting force can produce torsion, make drilling rod bit freezing or fracture, axis also easily is offset.
Summary of the invention
The objective of the invention is to consider the problems referred to above and a kind of torsion that inclined hole adds the feed in man-hour and the part cutting state when getting out produces of eliminating is provided, make drilling rod in whole boring procedure, all be in full state of contact with part always, finish the machining method of slant-hole machine of whole process.
Technical scheme of the present invention is: machining method of slant-hole machine of the present invention comprises the steps:
1) processes the end face vertical at vertical end face, with drilling rod and the vertically part elimination of the semi-cutting state between the end face with the Tool advance direction;
2) get out the position in boring, the arc surface of applying endoporus is expected to make a compensative material with processing, and compensative material is fixed at hole Working position and part;
3) start cutter, feed processing, feed is to the position of compensative material; Withdrawing then.
4) at last compensative material is cut off, whole process is finished in the end face polishing.
Above-mentioned steps 1) processes the end face vertical with milling cutter at vertical end face with the Tool advance direction.
Above-mentioned steps 2) compensative material is fixed with spot welding at hole Working position and part.
Therefore the present invention, can not produce semi-cutting state because employing all is the method that contacts entirely with part in the whole process of drilling rod, thereby guarantees the precision of processing, finishes process.Processing method of the present invention is simple and practical, has guaranteed the processing needs of inclined hole processing, is a kind of convenient and practical machining method of slant-hole machine.

The specific embodiment
Embodiment:
In the present embodiment structural representation of part to be processed as shown in Figure 1, an end face of part to be processed is a perpendicular 1, the other end is an arc surface 4, and the hole on the part and horizontal plane have certain included angle.
Machining method of slant-hole machine of the present invention comprises the steps:
1) processes the end face vertical 2 at vertical end face 1, with drilling rod and vertically part 3 eliminations of the semi-cutting state between the end face 1 with the Tool advance direction;
2) get out the position in boring, the arc surface 4 usefulness processing of applying endoporus is expected to make a compensative material 5, and compensative material 5 is fixed at hole Working position and part; Wherein arc surface 4 is transition structures, increases the intensity of member, avoids stress to concentrate.
3) start cutter, feed processing, feed is to the position of compensative material 5; Withdrawing then.
4) at last compensative material 5 is cut off, whole process is finished in end face 2 polishings.
In the present embodiment, above-mentioned steps 1) process the end face vertical 2 with milling cutter at vertical end face 1 with the Tool advance direction.
In the present embodiment, above-mentioned steps 2) compensative material 5 is fixed with spot welding at hole Working position and part.
It is in order to eliminate the semi-cutting state of cutter that this method is adopted in the processing of above-mentioned inclined hole, the size of this semi-cutting state influence is cut the distance L decision by hemisection, as shown in Figure 5, in practical operation, generally more than L＞20mm, will add compensative material, if L≤20mm, eliminate the influence of semi-cutting state by the rotating speed of the cutter that slows down, such as the processing of 1 ° of inclined hole, semi-cutting state just can not considered, without compensative material.If the skilled worker has surpassed 20mm and also can consider to add compensative material.
Among the present invention, drilling rod all contacts with part in whole process entirely, can not produce semi-cutting state, thereby has guaranteed the precision of processing, has finished process.
The present invention is not limited to above embodiment, so long as with this specification and claims book in the scheme that is equal to mentioned all can implement.
