Duan Sizhou installs multiple locating piece bearings by dormant bolt, and locating piece bearing is axially positioned in knife bar with positioning step B, positioning
PTFE locating pieces are installed with block bearing, after PTFE locating piece installations, outer face is coaxially disposed at one with knife bar
The face of cylinder on；Handle of a knife mounting seat is arranged on the cylindrical section of knife bar front end, is axially positioned in knife bar with positioning step A；Handle of a knife is pacified
Fill seat and fixation is coordinated by nut and the thread segment of knife bar front end, handle of a knife mounting seat is provided with the installation bolt for being used for installing handle of a knife.
It is further：The section of changeover portion is polygonized structure.
It is further：Changeover portion is rectangular parallelepiped structure, rectangular parallelepiped structure have with knife bar identical central axis, it is rectangular
Body structure sets locating piece bearing respectively in four faces of knife bar peripheral direction.
It is further：Locating piece bearing is U-shape structure, and a side of U-shape structure is connected with stop screw, U-shape structure
Another side cushion block, PTFE locating pieces are set gradually in U-shape structure, stop screw is connected to PTFE locating pieces side, made
Obtain the cell body center that PTFE locating pieces are fixed at U-shape structure.
It is further：Stop screw be arranged side by side it is multiple.
It is further：Nut is hexagonal big nut, for fixing handle of a knife mounting seat.
It is further：Handle of a knife mounting seat sets two blade installation structures, and makes to have before and after the installation of two blades
Difference.
The beneficial effects of the invention are as follows：In actual use, it is not necessary to overstriking knife bar diameter, in process, avoid
Knife bar is trembled, and part processing will not produce ripple, taper etc., it is ensured that machining accuracy.Knife bar front band positioner, front portion is used
PTFE is positioned, and solves the problems, such as that knife bar is sagging, while front and rear point all stress of knife bar, not by one direction stress, solves knife bar
Own wt influence, be applicable to roughing and finishing passes.Simultaneously using rough boring cutter process principle, before place
Two blades, a blade is higher 1mm than another blade, the shearing stress that each blade is subject to, cancels out each other, considerably increases
Cutting output.The allowance of rough turn endoporus has risen to 60mm-80mm, and hilted broadsword turning reaches 30mm-40mm, effectively improves life
Produce efficiency.Present invention is particularly suitable for the processing of big L/D ratio deep hole.

Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, the present invention includes knife bar 1, and the front end of knife bar 1 is the cylindrical structure being coaxially disposed, cylinder knot
Structure front end is thread segment, and cylindrical section is connected by changeover portion with knife bar 1, and positioning step A is formed between cylindrical section and changeover portion,
Positioning step B is formed between changeover portion and knife bar 1；Changeover portion surrounding installs multiple locating piece bearings 3 by dormant bolt 2, fixed
Position block bearing 3 is axially positioned in knife bar 1 with positioning step B, is installed with PTFE locating pieces 5 on locating piece bearing 3, PTFE is fixed
After the installation of block 5 of position, outer face is on the face of cylinder being coaxially disposed with knife bar 1；Handle of a knife mounting seat 7 is arranged on knife bar 1
The cylindrical section of front end, axially positioned in knife bar 1 with positioning step A；Handle of a knife mounting seat 7 passes through nut 8 and the screw thread of the front end of knife bar 1
Duan Peihe is fixed, and handle of a knife mounting seat 7 is provided with the installation bolt 9 for being used for installing handle of a knife.Nut 8 is hexagonal big nut, for fixing
Handle of a knife mounting seat 7.
Positioned for convenience of by PTFE locating pieces 5 in the radially installed of knife bar 1, the section of changeover portion is polygonized structure, this hair
