The technical scheme that provides according to the utility model: a kind of adjustable large-scale boring cutter; It is characterized in that: comprise a boring dish, two adjusting seats and two boring cutter seats; Its length direction of said boring dish upper surface upper edge offers first gathering sill; Regulate the two ends that a symmetry is installed in the boring dish for said two, regulate seat and be slidingly matched, but regulate seat and boring dish relative fixed through first guide pad and the formation of first gathering sill that its bottom is provided with; Its length direction of said adjusting seat upper surface upper edge offers second gathering sill; Said two boring cutter seats are installed in two accordingly and regulate on the seat; The boring cutter seat is slidingly matched through second guide pad and the formation of second gathering sill that its bottom is provided with, but a boring cutter seat and an adjusting seat relative fixed; Said boring cutter seat end has the boring head hole, is fitted with conventional fine setting boring head in the boring head hole.
As the further improvement of the utility model, said boring dish middle part offers and is used for the boring dish is fixed on the fixing hole on the machine tool chief axis; Said boring dish two ends offer several first locating holes that equidistantly distribute along its length, offer several adjustment holes that equidistantly distribute along its length on the said adjusting seat, and the adjustment hole and the first locating hole corresponding matching are used for fixing and regulate seat; The said seat end of regulating offers several second locating holes that equidistantly distribute along its length, offers second adjustment hole on the said boring cutter seat, and second adjustment hole and the second locating hole corresponding matching are used for fixing the boring cutter seat.Further, said second adjustment hole is a slotted hole.
As the further improvement of the utility model, said boring dish, adjusting seat and boring cutter seat all adopt 7075 aluminium alloys to process.
The utility model compared with prior art, advantage is: simple in structure, ingenious, reasonable, can be used for processing the circular hole of diameter greater than Φ 1400mm, whole light and flexible has high adjusting accuracy.

The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure: said adjustable large-scale boring cutter is mainly used in the large diameter circular hole of processing.It is mainly regulated 2 and two boring cutter seats 3 of seat and is formed by a boring dish 1, two.
Like Fig. 1 ~ shown in Figure 3; Said boring dish 1 its length direction of upper surface upper edge offers the first gathering sill 1a; Regulate the two ends that seat 2 symmetries are installed in boring dish 1 for said two; Regulate seat 2 and be slidingly matched, but regulate seat 2 and boring dish 1 relative fixed through the first guide pad 2c and the first gathering sill 1a formation that its bottom is provided with; Said adjusting seat 2 its length directions of upper surface upper edge offer the second gathering sill 2a; Said two boring cutter seats 3 are installed in two accordingly and regulate on the seat 2; Boring cutter seat 3 is slidingly matched through the second guide pad 3b and the second gathering sill 2a formation that its bottom is provided with, but a boring cutter seat 3 and adjusting seat 2 relative fixed; Said boring cutter seat 3 ends have boring head hole 3a, are fitted with commercially available routine fine setting boring head in the 3a of boring head hole.
Like Fig. 1 ~ shown in Figure 3, said boring dish 1, regulate installing and fixing between seat 2 and the boring cutter seat 3 and adopt following structure: said boring dish 1 middle part offers and is used for boring dish 1 is fixed on the fixing hole 1b on the machine tool chief axis; Said boring dish 1 two ends offer several the first locating holes 1c that equidistantly distributes along its length; The said adjusting offers several adjustment holes 2b that equidistantly distributes along its length on the seat 2; The adjustment hole 2b and the first locating hole 1c corresponding matching are used for fixing and regulate seat 2; Said seat 2 ends of regulating offer several the second locating holes 2d that equidistantly distributes along its length, offer the second adjustment hole 3c on the said boring cutter seat 3, and the second adjustment hole 3c and the second locating hole 2d corresponding matching are used for fixing boring cutter seat 3.In the present embodiment, the said second adjustment hole 3c is a slotted hole, can make boring cutter seat 3 realize stepless precise and tiny adjusting like this.
