Description
Technical field
This utility model relates to a kind of double blade internal lathe-tool.
Background technology
nullThe axis hole of the wheels such as Al-alloy motorcycle wheel hub and electric vehicle hub is I-shaped through hole，Axis hole both sides are the counterbore of pressing bearing，Middle for the through hole of spacer sleeve in placing，The counter bore hole diameters of bearing is more than the aperture of spacer，During pressing bearing，It first is pressed through the bearing of side at the bottom of dead eye，Middle spacer sleeve is put into after anti-for wheel hub one side，Press-fit the bearing of opposite side，The inner ring making two bearings is tightly pressed at together by middle spacer sleeve，Realize two bearing synchronous axial system，Under normal circumstances，The axis hole processing these wheel hubs once can only process counterbore and the through hole of side，Counterbore inside fixture just can be processed after needing anti-dress，Again clamping process there will be the impact such as clamping error and knife rest resetting error，Cause both sides dead eye not problem point-blank，Rotate smooth after causing bearing press mounting and block problem of waiting indefinitely，Therefore，It is very urgent for adopting the processing that rational method solves wheel hub both sides dead eye.
Summary of the invention
This utility model is intended at least solve one of technical problem of existence in prior art.
For this, the purpose of this utility model is in that, it is provided that a kind of double blade internal lathe-tool, to improve the collimation of the dead eye platform of axis hole both sides, reduces Clamped Positioning Error and mismachining tolerance.
For achieving the above object, embodiment of the present utility model provides a kind of double blade internal lathe-tool, including knife bar, front blade, rear blade and screw, the thin back segment of leading portion of described knife bar is thick, described knife rod head is provided with a blade and installs tangent plane, the cutting fluid conveying through hole leading to blade installation tangent plane from knife bar afterbody it is provided with inside described knife bar, described blade is installed tangent plane and is provided with two insert grooves that can install blade, two blade positions of described insert groove open at an angle, described front blade and described rear blade are fastened on described insert groove by described screw respectively, during cutting feed, the blade of described front blade is higher than the blade of described rear blade, when described front blade cut, described rear blade not with absorption surface.
The double blade internal lathe-tool that this utility model above-described embodiment provides, cutting fluid channel it is provided with inside knife bar, cutter is made still to have good cutting fluid lubrication and cooling effect when going deep into endoporus, slow down the abrasion that cutter causes because of cutting heating, extend cutter life, and cutting swarf is flushed out axis hole, the thin back segment of knife bar leading portion is slightly conducive to clamping and improves the intensity of cutter, cutter is conducive to go deep in tiny axis hole, reduce the cutter that shakes, two blades are angled to be opened, the blade of front blade is higher than the blade of rear blade, the interference between two cutters can be reduced, front blade carries out outboard counterbore and through hole adds man-hour, rear blade will not contact with workpiece hole wall, blade is arranged in insert groove by screw, more allowing blade replacement is convenient and swift.
It addition, the double blade internal lathe-tool that this utility model above-described embodiment provides also has following additional technical feature:
According to an embodiment of the present utility model, the difference in height of the two panels point of a knife of described front blade and described rear blade is more than described front blade or described rear blade cutting output once, and the level interval of the two panels cutting end point of a knife of described front blade and described rear blade is more than the counterbore degree of depth of workpiece to be processed side.
In above-described embodiment, the difference in height of the two panels point of a knife of front blade and rear blade is necessarily more than the cutting at one time amount of cutter, ensure before blade after adding man-hour blade not with workpiece axis hole contact internal walls, do not result in processing by mistake, the level interval of the sheet cutting end point of a knife of front blade and rear blade is more than the stomidium degree of depth of workpiece to be processed side, when making rear blade stretch out inboard bearing counterbore toward carriage return, outer blade will not encounter the axis hole end face of workpiece, thus can guarantee that outer blade car outboard bearing counterbore and through hole, rear blade car inboard counterbore, two panels blade is non-interference.
Additional aspect of the present utility model and advantage will become apparent upon in description below part, or recognized by practice of the present utility model.
Accompanying drawing explanation
Fig. 1 is cutter structure schematic diagram described in the utility model.
Detailed description of the invention
In order to be more clearly understood that above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with the drawings and specific embodiments, this utility model is further described in detail.It should be noted that when not conflicting, the feature in the embodiment of present patent application and embodiment can be mutually combined.
As shown in Figure 1:
This utility model provides a kind of double blade internal lathe-tool, to improve the collimation of the dead eye platform of axis hole both sides, reduces Clamped Positioning Error and mismachining tolerance, reduces the rotation fault rate of axis hole two side bearing and stuck problem.
For achieving the above object, including knife bar 1, front blade 2, rear blade 3 and screw 4, the thin back segment of leading portion of described knife bar 1 is thick, described knife bar 1 head is provided with a blade and installs tangent plane 11, described knife bar 1 is internal is provided with the cutting fluid conveying through hole 12 leading to blade installation tangent plane 11 from knife bar 1 afterbody, described blade is installed tangent plane 11 and is provided with two insert grooves 13 that can install blade, two blade positions of described insert groove 13 open at an angle, described front blade 2 and described rear blade 3 are fastened on described insert groove 13 by described screw 4 respectively, during cutting feed, the blade of described front blade 2 is higher than the blade of described rear blade 3, when described front blade 2 cuts, described rear blade 3 not with absorption surface.
