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
Sleeve nut's card slot of sleeve nut's installation.
The end face nut characterized by further comprising:Bearing for cooperating with bearing installation axle installs internal screw thread.
The bearing installation axle characterized by further comprising:End face nut external screw thread for cooperating with end face nut is used
In the part cutting ferrule conical surface cooperated with part cutting ferrule, threaded hole for being connected with screw, for and alignment bearing, thrust bearing
The periphery of cooperation.
Described its feature of part cutting ferrule further includes:Bearing for cooperating with bearing installation axle installs the conical surface, for closing up
Fastenings cracks, the step card slot for cooperating with part top bar.By tightening end face nut, make part cutting ferrule epicone
Face generates radial contraction, realizes the clamping of part.
The effect of the alignment bearing is that rotating accuracy with higher is pressed from both sides in guarantee, and the effect of thrust bearing is fixture
Axial force is born when reverse drawing part.
The part cutting ferrule inner diameter size can be designed according to diameter of part to be mounted, to adapt to the part of different-diameter
Clamping.Card slot diameter is 0.5-1mm bigger than interior circular diameter, to play the role of cooperating fastenings with part step.
The effect of the big lantern ring, small lantern ring is that the inner and outer ring of alignment bearing and thrust bearing is protected not generate axial position
It moves, improves bearing life, while must assure that lantern ring both ends of the surface meet higher depth of parallelism requirement.
The beneficial effects of the utility model:
