Abstract
The utility model relates to a machining tool, and provides a boring cutter. The boring cutter mainly solves the problems that coaxiality of machining two bearing holes is low and verticality of the end surfaces of the bearing holes and holes is low. The boring cutter comprises a front locating ring, a back locating ring, a boring shaft, a universal coupling mechanism and a boring cutter device. The front locating ring and the back locating ring are connected on the boring shaft through a copper bush in a rotating mode. Bolts are fixed on the outer ring of the front locating ring and the outer ring of the back locating ring. The boring cutter device is fixed on the outer side of the front locating ring or the outer side of the back locating ring. The universal coupling mechanism is fixed at one end of the boring shaft. The boring cutter device comprises a boring cutter row and a boring cutter feed mechanism, the boring cutter feed mechanism is fixed at one end of the boring cutter row, and a balance weight is fixed at the other end of the boring cutter row.
Description
Technical field
The utility model relates to the machining instrument, especially relates to a kind of borer of machining large dead eye.
Background technology
At 7MW and above dual-feed asynchronous wind power generator base front and back two large size bearings will be installed all, to improve precision and the life-span of main shaft, bearing diameter reaches
Front and back two bearings pitch-row is from 2.4 meters, and for precision and the life-span that guarantees main shaft, two bearings hole axiality is
Dead eye end face and hole perpendicularity are 0.25, and accuracy class reaches 6 grades, and just are the processing request that large-scale borer also be difficult to guarantee the perpendicularity in the axiality in two bearings hole and dead eye end face and hole.
The utility model content
Technical problem to be solved in the utility model provides a kind of borer, solves the not high defective of axiality perpendicularity low and dead eye end face and hole in existing processing two bearings hole.
For solving the problems of the technologies described above, the utility model borer, it is characterized in that, comprise: prelocalization circle, back centring ring, boring axle, Hook's coupling mechanism and boring cutter device, prelocalization circle and back centring ring are rotatably connected on the boring axle by copper sheathing, fixedly there is bolt outer ring at prelocalization circle and back centring ring, and the boring cutter device is fixed on the outside of prelocalization circle or back centring ring, and an end of boring axle fixedly has a Hook's coupling mechanism.
Preferable, above-mentioned boring cutter device comprises boring cutter row and boring cutter feed mechanism, and the boring cutter feed mechanism is fixed on an end of boring cutter row, and the other end fixedly has balance weight.
The utility model borer, the boring axle connects by Hook's coupling mechanism and boring bar, two boring cutter devices before and after the boring, be installed on the two bearings hole, front and back by bolt, front and back two large size bearing hole bore holes processing to 7MW and above dual-feed asynchronous wind power generator base, the processing in two bearings hole does not need mobile processed object, thus front and back two dead eye axialities of two large size bearings of processing than higher, dead eye end face and hole perpendicularity are also than higher.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, wherein identical label represents identical or similar parts in institute's drawings attached.It should be noted that the pattern of these accompanying drawings for simplifying in addition, only angle illustrates concrete enforcement structure of the present utility model from understanding easily.
As shown in Figure 1, the utility model borer, it is characterized in that, comprise: prelocalization circle 1, back centring ring 2, boring axle 3, Hook's coupling mechanism 4 and boring cutter device 5, prelocalization circle 1 and back centring ring 2 are rotatably connected on the boring axle 3 by copper sheathing 6, fixedly there is bolt 7 outer ring at prelocalization circle 1 and back centring ring 2, the boring cutter device is fixed on the outside of prelocalization circle or back centring ring, one end of boring axle 3 fixedly has a Hook's coupling mechanism 4, the boring cutter device comprises boring cutter row 8 and boring cutter feed mechanism 9, boring cutter feed mechanism 9 is fixed on an end of boring cutter row 8, and the other end fixedly has balance weight 10.
The utility model borer, boring axle 3 connects with boring bar by Hook's coupling mechanism 4, two boring cutter devices before and after the boring, be installed on the two bearings hole, front and back by bolt 7, front and back two large size bearing hole bore holes processing to 7MW and above dual-feed asynchronous wind power generator base, the processing in two bearings hole does not need mobile processed object, thus front and back two dead eye axialities of two large size bearings of processing than higher, dead eye end face and hole perpendicularity are also than higher.
Below the preferred embodiment of the utility model having been created specifies, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, the modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
