Description
Technical field
The invention belongs to tooling and fixture technical field, are related to a kind of bracket, especially a kind of bracket of slender shaft turning.
Background technique
In turning process, conventional processing method of slender axle is using toolings such as top, follow-rest and centre frames
Fixture carries out clamping, but problem of the prior art is:
L, it is easy to appear " rope skipping " phenomenon: since elongated shaft rigidity itself is poor, when by elongated shaft clamping on lathe,
It is sagging to occur bent intermediate because of own wt elongated shaft under no external force, by lathe tool axial direction in turning process
Cutting force, radial cutting force and top axial pressing force effect and easily occur bending and deformation, vibrate, knife the problems such as.
2, thermal deformation is big: since the heat diffusivity during Turning of Slender Shaft is poor, being easy to produce cutting thermal linear expansion, especially
It is the processing method based on one top of in the prior art one folder, elongated shaft easily generates bending deformation.
3, tool wear is big: since slender shaft turning cutting data is less, long processing time, tool wear is big, is also easy to produce
Circularity, concentricity, the geometric tolerances such as taper value and surface roughness value are unqualified.
4, processing disadvantage is more: during slender shaft turning, it is desirable that horizontal corresponding higher, one ring of processing link of operating technology
A ring is detained, deals with improperly and waste product easily occurs, while the adjustment auxiliary tool of lathe is used, tool geometrical parameter, cutting is used
The selection of amount etc. is proposed compared with strict requirements.
A kind of Turning of Slender Shaft frock clamp as disclosed in Chinese patent literature (application number: 201220303614.3), packet
The second technical clamp for including the first technical clamp for being fixed on the first chuck of lathe and being fixed on the second chuck of lathe, tail stock set letter
On be provided with the clamp body with cylindric inner cavity, be connected with the second chuck and be provided with mandrel, mandrel is through the bottom of clamp body, the heart
