Background technology
Lathe tool is for turnery processing, the cutter with a cutting tip.Boring cutter is most widely used in machining
One of cutter.Endoporus turning is the basic skills of five metalworking China and foreign countries disc processing, and therefore inner hole boring tool is in lathe tool field
Have a very important role.Traditional inner hole boring tool structure is complicated, complex operation, requires to need for different turning processes
Change different inner hole boring tools, not only by loaded down with trivial details to boring cutter dismounting and exchonge step, have impact on production efficiency；Easily cause brill simultaneously
Head and the damage of workpiece, service life is short, needs often maintenance or renewal part.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, it is provided that a kind of adjustable inner hole essence
Boring cutter.
This utility model solves its technical problem and be the technical scheme is that a kind of adjustable inner hole fine boring cutter, including cutter
Body and front regulation screw, cutter hub front end uniformly offers multiple skewed slot, and skewed slot is built-in with cutter head；Described cutter hub is built-in with mandrel,
Cutter hub tail end is provided with adjusting nut, and mandrel afterbody is threadeded with adjusting nut integrally formed with screw rod, screw rod；Described cutter hub
On be provided with briquetting fixing for cutter head, front regulation screw is connected with mandrel nose threads after briquetting, cutter head, mandrel, front
Regulation screw and briquetting form black box；The locking nut that locking mandrel prevents mandrel from rotating is installed on described cutter hub；Institute
The angle α stated between the skewed slot longitudinal center line of cutter hub and front regulation screw axial centrage is 15～45 °；Described cutter hub appearance
Face is provided with the LED for illumination.
Further, described cutter hub tail end is provided with and blocks the block that adjusting nut moves to mandrel, and adjusting nut is embedded
It is located at cutter hub tail end.
Further, described mandrel offering the strip stopper slot corresponding with locking nut, locking nut is worn
The base propping up stopper slot after crossing cutter hub prevents mandrel from rotating.
Further, the angle α between skewed slot longitudinal center line and the front regulation screw axial centrage of described cutter hub is
20°。
Further, described cutter hub afterbody is provided with the conus portion being easy to that cutter hub loads knife rest.
The beneficial effects of the utility model are: this utility model simple in construction, reasonable in design, easy and simple to handle, service life
Long, rotate adjusting nut, the length of mandrel extension can be regulated under screw acting, so that cutter head is along the skewed slot shifting of cutter hub
Dynamic, it is achieved the size variation of cutter head rotating diameter, to adapt to different turning process requirements, service life is long simultaneously, it is not necessary to
Often maintenance or renewal part, improve work efficiency.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
1. cutter head in figure, 2. before regulate screw, 3. cutter hub, 4. mandrel, 5. lock-screw, 6. adjusting nut, 7. briquetting, 8.
