Abstract
The invention provides a precise boring tool, a locating shaft is arranged on the end portion of a toolbar, eccentricity exists between the axis of the locating shaft and the axis of the toolbar, a screw rod is arranged on the end portion of the locating shaft, the screw rod and the locating shaft are provided with an identical axis, a tool apron is installed on the excircle of the locating shaft through an eccentric hole in the toolbar, a boring tool bit is installed and fixed on the tool apron in the direction of the farthest eccentric distance away from the tool apron through a fixing bolt, a press plate and a locking nut are installed on the screw rod, an angle scale is arranged on the back surface of the tool apron, and a pointer is arranged in the generatrix line direction of the excircle of the toolbar. The precise boring tool has the advantages of being simple in structure, convenient to use, high in regulation precision, and high in labor productivity.
Description
Technical field
The present invention relates to a kind of accurate boring cutter, belong 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 present invention is directed to the existing existing defects of boring cutter, the invention provides a kind of accurate boring cutter, overcome the existing existing defects of boring cutter.
a kind of accurate boring cutter of the present invention, 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 present invention 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 invention and operation principle, the present invention 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.
Description of drawings
Accompanying drawing is theory structure front view of the present invention;
Shown in figure: 1, knife bar; 2, pointer; 3, angle scale; 4, set bolt; 5, cutter head; 6, tool rest; 7, pressing plate; 8, locking nut; 9, screw rod; 10, locating shaft.
The specific embodiment
be shaped with locating shaft (10) in the end of knife bar (1), has bias between the axis of the axis of described locating shaft (10) and knife bar (1), be shaped with screw rod (9) in the end of locating shaft (10), screw rod (9) has identical axis with locating shaft (10), tool rest (6) is arranged on the cylindrical of locating shaft (10) by the eccentric orfice on it, install with set bolt (4) on the direction of the eccentric distance farthest of distance tool rest (6) and fix a cutter head (5), pressing plate (7) and locking nut (8) are installed on screw rod (9), be provided with angle scale (3) at the back side of tool rest (6), generatrix direction at knife bar (1) cylindrical is shaped with pointer (2).
