Description
Technical field
The utility model belongs to Aeronautics and Astronautics manufacturing, is related to the processing of thin and long shafts part, specially a kind of elongated
Axial workpiece turning clamp.
Background technique
In the manufacturings such as Aeronautics and Astronautics, automobile, there are a large amount of thin and long shafts parts, when such part draw ratio
After 30, difficulty of processing is in significantly to increase.Conventional Machining of Shaft-type Parts mode be on center lathe using chuck and
Top " one top of a folder " mode is processed, and when major diameter is smaller, this processing method does not embody obvious shortcoming, but when length
Diameter than it is very big when（Such as more than 30）Afterwards, under the influence of the pressure of " one top of a folder " mode, part machining deformation is obvious, and part goes out
It is now bent, " waist drum " shape feature occurs in part after processing, and machining accuracy is difficult to ensure.To improve processing quality, existing improvement
Measure includes increasing follow-rest, using the modes such as double-pole vehicle instead, or being realized in numerically controlled lathe using ANSYS mathematical analysis modeling
The modes such as real-time compensation, or reduce processing efficiency by experience technician very rich and guarantee, it is all to solve such as with upper type
What improves the workpiece bending deformed measure of big L/D ratio.It how to be inherently eliminated the clamping deformation of such part, is not obtain
To what is effectively solved.
Utility model content
In view of the deficiency of the prior art, the utility model provides a kind of thin and long shafts part turning clamp.
A kind of thin and long shafts part turning clamp, it is characterised in that including：General barrel of tail stock, big lantern ring, small lantern ring, set
Cylinder nut, end face nut, screw, gasket, bearing installation axle, part cutting ferrule, alignment bearing and thrust bearing, the general tailstock
Sleeve, big lantern ring, small lantern ring, sleeve nut, end face nut, screw, gasket, bearing installation axle, part cutting ferrule, alignment bearing and
Thrust bearing contacts with each other to form fixture entirety.
The barrel of tail stock characterized by further comprising：For tail stock cooperation periphery, for and alignment bearing,
The inner headed face of thrust bearing cooperation, the internal screw thread for cooperating with sleeve nut, the screw thread for being connected with tail stock handle
Hole.
The periphery diameter is 75-85mm.
The sleeve nut characterized by further comprising：Barrel of tail stock external screw thread for cooperating with barrel of tail stock, is used for
