Abstract
The utility model belongs to machine tool technologies, and relates to a milling cutter adaptor of a milling machine main shaft. The milling cutter adaptor of the milling machine main shaft is composed of a Morse taper shank (2) and an adaptor body (3), a Morse taper hole (5) is formed in the lower end face of the adaptor body (3), an oblong location hole (4) is formed in the cylindrical surface of the adaptor (3), is through axially and stretches along the axial direction, and the lower end of the oblong location hole (4) is communicated with the hole bottom of the Morse taper hole (5). The length of the main shaft of a milling machine can be extended, the milling cutter adaptor of the milling machine main shaft facilitates machining of the workpieces which are relatively deep or narrow in cavity, or abrupt in molded surface, and the phenomena of cutter relieving and overcut caused by the facts that a cutter bar is overlength and a cutter is insufficient in rigidity in a machining process are prevented.
Description
Technical field
The utility model belongs to the machine tool technology, relates to a kind of milling machine spindle milling cutter adapter.
Background technology
Add man-hour at milling machine, often run into the situations such as the workpiece to be processed die cavity is dark, die cavity is narrow, profile is precipitous, only have long cutter could process such part.But cutter length is long, and is will rigidity not enough, cutter relieving often can occur in process and cross the phenomenon of cutting.
Summary of the invention
The purpose of this utility model is: propose a kind of milling cutter adapter that can extend milling machine spindle, so that the workpiece such as processing cavity is dark, die cavity is narrow, profile is precipitous prevents from occuring in process cutter relieving and crosses the phenomenon of cutting.
the technical solution of the utility model is: a kind of milling machine spindle milling cutter adapter, it is characterized in that, it is connected to form by Morse taper shank 2 and chovr body 3, the profile of chovr body 3 is cylinder, the lower end of Morse taper shank 2 and the coaxial integral body that is connected in the upper end of chovr body 3, it is the locating piece 1 of rectangle that cross section is arranged in the upper end of Morse taper shank 2, at the bottom of the hole of the width dimensions of locating piece 1 and milling machine spindle Morse taper hole, the width dimensions of locating hole is identical, the vertical bisector plane of the width of locating piece 1 is by the axis of Morse taper shank 2, a Morse taper hole 5 is arranged on the lower surface of chovr body 3, this Morse taper hole 5 is blind hole, the inner chamber overall size of this Morse taper hole 5 is identical with the inner chamber overall size of milling machine spindle Morse taper hole, the dead in line of the axis of this Morse taper hole 5 and Morse taper shank 2, there is one radially to connect on the face of cylinder of chovr body 3, the oval locating hole 4 that stretches vertically, connect at the bottom of the hole of the lower end of oval locating hole 4 and Morse taper hole 5, at the bottom of the hole of the width dimensions of oval locating hole 4 and milling machine spindle Morse taper hole, the width dimensions of locating hole is identical, the vertical bisector plane of the width of oval locating hole 4 is coplanar with the vertical bisector plane of locating piece 1 width, the axial length of oval locating hole 4 is greater than the axial length of locating piece 1.
The utility model has the advantages that: can extend the main axis length of milling machine, be convenient to the workpiece such as processing cavity is dark, die cavity is narrow, profile is precipitous, prevent from cutter relieving occuring because arbor stiffness is not enough and crossing the phenomenon of cutting.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The below is described in further details the utility model.referring to Fig. 1, a kind of milling machine spindle milling cutter adapter, it is characterized in that, it is connected to form by Morse taper shank 2 and chovr body 3, the profile of chovr body 3 is cylinder, the lower end of Morse taper shank 2 and the coaxial integral body that is connected in the upper end of chovr body 3, it is the locating piece 1 of rectangle that cross section is arranged in the upper end of Morse taper shank 2, at the bottom of the hole of the width dimensions of locating piece 1 and milling machine spindle Morse taper hole, the width dimensions of locating hole is identical, the vertical bisector plane of the width of locating piece 1 is by the axis of Morse taper shank 2, a Morse taper hole 5 is arranged on the lower surface of chovr body 3, this Morse taper hole 5 is blind hole, the inner chamber overall size of this Morse taper hole 5 is identical with the inner chamber overall size of milling machine spindle Morse taper hole, the dead in line of the axis of this Morse taper hole 5 and Morse taper shank 2, there is one radially to connect on the face of cylinder of chovr body 3, the oval locating hole 4 that stretches vertically, connect at the bottom of the hole of the lower end of oval locating hole 4 and Morse taper hole 5, at the bottom of the hole of the width dimensions of oval locating hole 4 and milling machine spindle Morse taper hole, the width dimensions of locating hole is identical, the vertical bisector plane of the width of oval locating hole 4 is coplanar with the vertical bisector plane of locating piece 1 width, the axial length of oval locating hole 4 is greater than the axial length of locating piece 1.
Using method of the present utility model is: when the workpiece such as processing cavity is dark, die cavity is narrow, profile is precipitous, at first the Morse taper shank with this milling machine spindle milling cutter adapter is arranged in the mohs tapered bore of milling machine spindle, and the Cutting tool installation manner that then will use is in the lower end mohs tapered bore of this milling machine spindle milling cutter adapter.Just can carry out Milling Process after installing.Use by this milling machine spindle milling cutter adapter not only can extend the distance of cutter and former milling machine spindle, has also improved the processing stability of cutter simultaneously.
