Description
Technical field
The invention belongs to technical field of tooling clamps, relate to a kind of bracket, particularly a kind of
The bracket of slender shaft turning.
Background technology
In turning process, conventional processing method of slender axle is that use is top, with cutter
The frock clamp such as frame and centre frame carries out clamping, but problem of the prior art is:
L, easily appearance " rope skipping " phenomenon: owing to the rigidity of slender axles own is poor, when by thin
When major axis clamping is on lathe, even if also can go out because of own wt without slender axles under External Force Acting
Existing bent intermediate is sagging, its in turning process by lathe tool axial cutting force, radial cutting force
And the effect of top axial pressing force and easily occur bending and deformation, vibrate, the problem such as knife.
2, thermal deformation is big: owing to the heat diffusivity during Turning of Slender Shaft is poor, easily produce
Raw cutting thermal linear expansion, is based particularly on the processing mode on folder one top in prior art, carefully
Major axis easily produces flexural deformation.
3, tool wear is big: owing to slender shaft turning cutting data is less, long processing time,
The form and position tolerance values such as tool wear is big, is easily generated circularity, axiality, tapering and surface are thick
Rugosity value is defective.
4, processing disadvantage is many: during slender shaft turning, it is desirable to operating technology level phase
Should be higher, processing link is closely linked, deals with improperly and waste product easily occurs, simultaneously to machine
The adjustment aid of bed uses, and tool geometrical parameter, the selection of the aspects such as cutting data carries
Go out relatively strict requirements.
As disclosed in Chinese patent literature a kind of Turning of Slender Shaft frock clamp (application number:
201220303614.3), including being fixed on the first technical clamp of lathe the first chuck and fixing
It is provided with in band cylindrical shape on the second technical clamp of lathe the second chuck, tail stock set letter
The clamp body in chamber, is connected with the second chuck and is equipped with mandrel, and mandrel runs through the bottom of clamp body,
Mandrel is socketed with bearing group and circular arc packing ring being positioned at clamp body lumen portion, uses first
Technical clamp and slender axles being entered with the second technical clamp being rotationally connected by mandrel and clamp body
Luggage presss from both sides.But during this frock clamp clamping slender shaft turning, easily it is deformed and makes processing
Precision is the highest.
