Technical field
The utility model belongs to Turning of Slender Shaft processing technique field, and in particular to a kind of slender shaft turning clamping tooling.
Background technique
Elongated shaft is exactly that the length-to-diameter of workpiece is greater than the axial workpiece of 25 (i.e. L/D > 25), and hydraulic pressure draw-bar is adopted
Coal machine backplate connecting shaft belongs to slender rod type part.Traditional installation way that turning elongated shaft uses on lathe mainly has two
Kind: a kind of mode is that one end of elongated shaft is clamped with chuck, and the other end is supported with tail stock vertex, i.e., a so-called " folder one
Top " installation way；Another way is that top support, i.e. " Double Tops point clamping " are used in the both ends of elongated shaft.
For the installation way of " one folder one top ", in Tutrning Process, if top push up too tight, in addition to can
Can will be outside elongated shaft bending, moreover it is possible to when hindering turning elongated shaft by thermal stretching, cause elongated shaft to be compressed axially and generated
Bending deformation.In addition, claw clamping face may not be coaxial with center hole, positioning can be generated after clamping, can result in elongated shaft
Generate bending deformation.Therefore, the installation way on " one top of a folder " is obviously unable to satisfy the quality requirement of product.
And for the installation way of " Double Tops point clamping ", in Tutrning Process, elongated shaft bending deformation itself
It is larger, rigidity is poor, and is easy to produce vibration, this installation way is often only applicable to that installation major diameter is little, machining allowance
Workpiece smaller, concentricity is more demanding.
Utility model content
