The large-scale irregular parts are thick, fine finishining one boring cutter
The utility model belongs to machining tool, and particularly a kind of large-scale irregular parts are thick, fine finishining one boring cutter.
At present, in large-scale irregular parts process, for the aperture greater than the parts of ￠ more than 600; Be difficult to buy the boring cutter of appropriate size, can only customize boring cutter according to actual needs, and be thick, fine boring cutter separately; Cutter processing dimension adjustable extent is little; The cutter fabrication cycle is long, and price is high, and result of use is not ideal enough.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of simple in structure, cost is low, and smart, roughing is one, thick, the fine finishining one boring cutter of the large-scale irregular parts that machining accuracy is high.
The technical scheme that the utility model technical solution problem is adopted is: a kind of large-scale irregular parts are thick, fine finishining one boring cutter; It is characterized in that boring cutter body and function boring cutter body set bolt is fixed on the boring spindle; The boring cutter body is tightly fixed with mounting flange and is connected; The mounting flange center is provided with spindle hole, and the left end of boring cutter body is adjusted on the slide plate with roughing boring head of roughing boring head bolt on a left side with a left side adjustment of a plurality of bolt slide plate; Add blade with the fixing roughing machine of thick plough bolt on the roughing boring head, the roughing blade presses nail fixing with machine tooled knife; Right-hand member at the boring cutter body is adjusted slide plate with the fixing right side that is provided with dovetail groove of a plurality of dormant bolts; In dovetail groove, adorn a slide plate of dovetail groove adjustment versatilely; On dovetail groove adjustment slide plate, adorn a fine boring head, trim button and fine finishining blade are housed on fine boring head.
The beneficial effect of the utility model is: use that these large-scale irregular parts are thick, fine finishining one boring cutter has solved the processing problems in the large-scale aperture of large-scale irregular parts; The processing pore diameter range is big; Roughing efficient is fast, and the fine finishining precision is high, and is easy to use, quick; Avoid frequent tool changing, cost is low.

The specific embodiment
Embodiment; With reference to accompanying drawing, a kind of large-scale irregular parts are thick, fine finishining one boring cutter, it is characterized in that boring cutter body 6 usefulness boring cutter main shaft set bolts 7 are fixed on the boring cutter main shaft; Boring cutter body 6 is tightly fixed with mounting flange 12 and is connected; The center of mounting flange 12 is provided with spindle hole 16, and the left end of boring cutter body 6 is fixed roughing boring heads 2 with roughing boring head set bolt 17 with eight bolts, 4 a fixing left side adjustment slide plates 3 on left side adjustment slide plate 3; Add blade 1 with thick plough bolt 18 fixing roughing machines on the roughing boring head 2, the roughing machine adds blade 1 usefulness machine tooled knife and presses nail 14 fixing; Right-hand member at boring cutter body 6 is adjusted slide plates 13 with ten dormant bolts, 11 fixing right sides that are provided with dovetail groove; In dovetail groove, adorn a slide plate 8 of dovetail groove adjustment versatilely; On dovetail groove adjustment slide plate 8, adorn a fine boring head 9, trim button 10 and fine finishining blade 15 are housed on fine boring head 9.Main shaft fixedly is housed in spindle hole 16, on boring cutter axle mounting flange 12, mainshaft cap 19 is housed.At suspension ring 5 of center fixed of boring cutter body 6, convenient lifting.
The course of work is like this, drives boring cutter body 6 during main axis rotation and rotates, and the length of boring cutter body 6 adds blade 1 with the roughing machine earlier and carries out roughing according to the design of process component pore size, carries out fine finishining with fine finishining blade 15 again.Can adjust slide plate 12 with dovetail groove during fine finishining and on boring cutter body 6, adjust distance, but fine boring head 9 uses is special-purpose band tool changing, adjustable other boring cutter module of scale um level.
