Embodiment
In order that those skilled in the art more fully understand the utility model scheme, below in conjunction with the accompanying drawings and specific implementation
The utility model is described in further detail for mode.
Fig. 1 is refer to, the utility model embodiment provides a kind of integral type compound fine setting fine boring head.
The fine boring head includes boring head body 1, adjusting means and handle of a knife 2, and boring head body 1 and handle of a knife 2 are integrated, circle
The handle of a knife 2 of platform shape is built into top surface radius at the lower end of boring head body 1, handle of a knife 2 and is more than bottom surface radius.
The bottom center of handle of a knife 2 is configured with a blind hole, for connecting handle of a knife bar.
The boring head body 1 and handle of a knife 2 of integration overcome conventional two-piece boring cutter because split-type structural is during bore hole
Unstable easy eccentric shortcoming is easily vibrated, the precision and operating efficiency of bore hole is improved.
Boring head body 1 is configured with the through hole of a rotation radial direction, for accommodating device for installing and adjusting, boring head body 1
Top surface be configured with a hole, vertical with above-mentioned through hole, lower end is connected with through hole.
Adjusting means includes dial 3, dish-like shell fragment 4, clamp nut 5, copper nut 6 and movable axis 7, and dial 3 includes
Card, the centrally disposed screw rod of card, screw rod passes through dish-like shell fragment 4, clamp nut 5 and copper nut 6.Movable axis 7 is configured with
Copper nut mounting hole, copper nut 6 is embedded into copper nut mounting hole, makes the outer wall of copper nut 6 and copper nut mounting hole inwall close
Laminating.Movable axis 7 is configured with the mounting hole 8 of a boring head axial rotary, and position is corresponding with the top surface hole site of boring head body 1, makes boring
Cutter head can be embedded in the mounting hole 8 of movable axis 7 through boring head body top surface hole.
The side of movable axis 7 placement configurations vertical with cutter head mounting hole have a waist type fixing hole, and waist type fixing hole is long
Direction of principal axis is parallel with through hole, and the placement configurations corresponding with waist type fixing hole of boring head body 1 have a fixing hole, and screw, which is passed through, to be fixed
