Utility model content
The purpose of this utility model is the fastening means providing a kind of simple and reasonable face milling cutters, and the fastening means of these face milling cutters adopts main shaft end face and excircle orientation, makes system connect rigidity better, is conducive to ensureing to promote crudy and high-speed cutting.In addition, only need install and remove cutter at ordinary times, need not fastening means be installed and removed, so the positioning precision of main shaft and fastening means can not be destroyed; Further, because the installation of face milling cutters and taper hole, tensioning mechanism have nothing to do, taper hole and tensioning mechanism need not be repaired, avoid overhaul lathe.
For achieving the above object, the utility model provides the fastening means of face milling cutters, this fastening means is three grades of multidiameter structures, specifically comprise: the macro-axis be connected with machine tool chief axis, the little axle be connected with cutterhead and the axis connecting macro-axis and little axle, the outer end of described macro-axis offers the positioning spigot of locating with the end face of machine tool chief axis and cylindrical adaptation.
Preferably, in technique scheme, the outer end of macro-axis offers the circular positioning spigot of indent.
Preferably, in technique scheme, the step surface of macro-axis and axis transition circumferentially evenly offers multiple bolt hole.
Preferably, in technique scheme, bolt hole is four.
Preferably, in technique scheme, the axis of the macro-axis on bolt hole edge is offered, and one end is bolt head counterbore, and the other end is through to the circular positioning spigot of macro-axis outer end.
Preferably, in technique scheme, little axle has the periphery of installing with the installing hole adaptation of cutterhead, and the outer end central authorities of described little axle also offer screwed hole.
Preferably, in technique scheme, macro-axis, little axle and axis are cylindric.
Compared with prior art, the utility model has following beneficial effect: the fastening means of these face milling cutters adopts main shaft end face and excircle orientation, makes system connect rigidity better, is conducive to ensureing to promote crudy and high-speed cutting.In addition, only need install and remove cutter at ordinary times, need not fastening means be installed and removed, so the positioning precision of main shaft and fastening means can not be destroyed; Further, because the installation of face milling cutters and taper hole, tensioning mechanism have nothing to do, taper hole and tensioning mechanism need not be repaired, avoid overhaul lathe.

Fig. 3 is the using state structural representation of the fastening means of face milling cutters of the present utility model;
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As shown in Figures 2 and 3, be three grades of multidiameter structures according to the fastening means 23 of the face milling cutters of the utility model detailed description of the invention, specifically comprise: the macro-axis 231 be connected with machine tool chief axis, the little axle 232 be connected with cutterhead and the axis 233 connecting macro-axis 231 and little axle 232, wherein, the outer end of macro-axis 231 is by tightening on screw 24 on main shaft 25.Little axle 232 is tightened by screw 21 and cutterhead 22.Owing to using main shaft end face and excircle orientation, so taper hole, tensioning mechanism are irrelevant, taper hole and tensioning mechanism need not be repaired; Owing to only cutter need be installed and removed at ordinary times, fastening means need not be installed and removed, so the positioning precision of main shaft and fastening means can not be destroyed; Because main shaft is comparatively large, it is better that this location makes system connect rigidity, is conducive to ensureing to promote crudy and high-speed cutting.
Specifically, as shown in Figure 2, the outer end of macro-axis 31 offers the circular positioning spigot of indent, for locating with end face and the cylindrical adaptation of machine tool chief axis, owing to using main shaft end face and excircle orientation, so taper hole, tensioning mechanism are irrelevant, taper hole and tensioning mechanism need not be repaired; Owing to only cutter need be installed and removed at ordinary times, fastening means need not be installed and removed, so the positioning precision of main shaft and fastening means can not be destroyed; Because main shaft is comparatively large, it is better that this location makes system connect rigidity, is conducive to ensureing to promote crudy and high-speed cutting.Macro-axis 231 circumferentially evenly offers multiple bolt hole with the step surface of axis 233 transition, and preferably, this bolt hole is four.The axis of the macro-axis 231 on the overall edge of this bolt hole is offered, one end is bolt head counterbore, the other end is through to the circular positioning spigot of macro-axis 231 outer end, after the circular positioning spigot of macro-axis 231 outer end and the end face of machine tool chief axis and cylindrical adaptation locates, then pass this bolt hole tighten on main shaft 25 by tightening screw 24.The head tightening screw 24 sinks to the bolt head counterbore of this bolt hole, when avoiding the fastening means of these face milling cutters to rotate and miscellaneous part interfere.
Little axle 232 has the periphery of installing with the installing hole adaptation of cutterhead 22, the outer end central authorities of little axle 232 offer screwed hole, cutterhead 22 is arranged on after on little axle 232, then by screw 21 through cutterhead 22 and screw hole, to realize tightening of little axle 232 and cutterhead 22.
Preferably, the macro-axis 231 be connected with machine tool chief axis, the little axle 232 be connected with cutterhead and the axis 233 connecting macro-axis 231 and little axle 232 are cylindric.
To sum up, the fastening means of these face milling cutters adopts main shaft end face and excircle orientation, makes system connect rigidity better, is conducive to ensureing to promote crudy and high-speed cutting.In addition, only need install and remove cutter at ordinary times, need not fastening means be installed and removed, so the positioning precision of main shaft and fastening means can not be destroyed; Further, because the installation of face milling cutters and taper hole, tensioning mechanism have nothing to do, taper hole and tensioning mechanism need not be repaired, avoid overhaul lathe.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
