Abstract
Provided is a precise boring cutter. A locating shaft is arranged at the end portion of a cutter rod. Decentration exists between the axis of the locating shaft and the axis of the cutter rod. A screw is arranged at the end portion of the locating shaft. The axis of the screw is the same to that of the locating shaft. A cutter base is arranged on an outer circle of the locating shaft through an eccentric hole formed in the cutter base. A boring tool bit is fixedly arranged on the direction of the farthest eccentric distance from the cutter base through a fixing bolt. A pressing plate and a locking nut are arranged on the screw. An angle dial is arranged at the back of the cutter base. A pointer is arranged on the generatrix direction of the outer circle of the cutter rod. The precise boring cutter has the advantages of being simple in structure, convenient to use, relatively high in adjustment accuracy, and high in labor productivity.
Description
Technical field
The utility model relates to a kind of accurate boring cutter, belongs to the machine tool technical field.
Background technology
At present, the boring cutter that is used for bore hole generally is comprised of knife bar and the cutter head that is fixed on knife rod head, so, the diameter of its bore hole is changeless, for the circular hole of boring different-diameter processed, must readjust cutter head, and through repeatedly trying bore hole and then the position of cutter head being fixed, so, exist and use trouble and the lower defective of efficient; Although also there are at present some can the adjustable boring cutter of bore size,, this class boring cutter generally exists structure comparatively complicated, adjusts the relatively poor defective of precision.
Summary of the invention
The utility model is for the existing defects of existing boring cutter, and the utility model provides a kind of accurate boring cutter, overcomes the existing existing defects of boring cutter.
a kind of accurate boring cutter described in the utility model, it is by knife bar, pointer, angle scale, set bolt, cutter head, tool rest, pressing plate, locking nut forms, it is characterized in that: the end of knife bar is shaped with locating shaft, has bias between the axis of described locating shaft and the axis of knife bar, end at locating shaft is shaped with screw rod, described screw rod has identical axis with locating shaft, tool rest is arranged on the cylindrical of locating shaft by the eccentric orfice on it, install with set bolt on the direction of the eccentric distance farthest of distance tool rest and fix a cutter head, pressing plate and locking nut are installed on screw rod, the back side at tool rest is provided with angle scale, generatrix direction at the knife bar cylindrical is shaped with pointer.
Beneficial effect: when the utility model changes bore diameter at needs, only the corresponding knife bar of tool rest need to be rotated a certain angle, and utilize trigonometric function to calculate the lifting distance of point of a knife through the number of degrees on angle scale, can be found out by structural front view of the present utility model and operation principle, the utility model not only has advantages of simple in structure, easy to use; Have advantages of also that simultaneously degree of regulation is higher, and can effectively raise labour productivity, advantage easy to use.
