Abstract
A clamping bulkhead for rotation of thin-wall parts of steam-turbine shaft relates to a shaft centering and clamping tool. The utility model solves the problem that the outer circle of the prior thin-wall parts of the steam-turbine shaft is likely to generate deformation during turning. The clamping bulkhead comprises two semi-ring press plates (1), a pedestal (2) and housing screws (3), wherein the annular pedestal (2) has a positioning spigot (2-1); the two semi-ring press plates (1) are symmetrically arranged to form a ring plate fixed on the pedestal (2); the semi-ring press plates (1) have screw holes (1-1) thereon; and the housing screws (3) are arranged in the screw holes (1-1). The clamping bulkhead can reduce the clamping force of the thin-wall parts of steam-turbine shaft during turning so as to reduce the deformation amount of the outer circle and control the deformation amount within 0.02 mm.
Description
Technical field
The utility model relates to a kind of class centering clamping tool.
Background technology
Steam turbine has a lot of class thin-walled revolution parts, and between 200-360mm, length is greater than 1500mm mostly for its internal diameter, and wall thickness is less than 7mm, and processing back cylindricity should be less than 0.02mm.This class part bowlder outside finish turning, the improper part that very easily causes of clamping deforms because of the excessive cylindrical of clamping force, even in thin-wall part endoporus assembling silently, because the magnitude of interference is arranged, the outer fenestra of pulling down behind the thin-wall part silently can deform.
The utility model content
The purpose of this utility model is the problem that cylindrical easily deforms in order to solve existing turbine shaft class thin-wall part and to carry out turning and provide a kind of turbine shaft class thin-wall part revolution with clamping silently.The utility model is made up of two semi-ring pressing plates 1, base 2 and housing screw 3; Two semi-ring pressing plates 1 are symmetrical arranged forms a Circular Plate, and Circular Plate is packed on the base 2, and semi-ring pressing plate 1 is provided with screw 1-1, and housing screw 3 is installed in the screw 1-1.
The utlity model has following beneficial effect: the clamping force when the utility model has reduced the turning of turbine shaft class thin-wall part, the problem that the cylindrical deflection is reduced is controlled at the cylindrical deflection in the 0.02mm.
Description of drawings
Fig. 1 is overall structure master's pseudosection of the present utility model, and Fig. 2 is an overall structure vertical view of the present utility model.
The specific embodiment
The specific embodiment one: in conjunction with Fig. 1 and Fig. 2 present embodiment is described, present embodiment is made up of two semi-ring pressing plates 1, base 2 and housing screw 3; Base 2 is an annular, and base 2 is provided with positioning spigot 2-1, and two semi-ring pressing plates 1 are symmetrical arranged forms a Circular Plate, and Circular Plate is packed on the base 2, and semi-ring pressing plate 1 is provided with screw 1-1, and housing screw 3 is installed in the screw 1-1.During processing vapor turbine axis class thin-wall part, can be earlier the positioning boss of thin wall component be placed in the positioning spigot of base, then the semi-ring pressing plate is installed on the base, hold out against thin wall component ring flange end face with housing screw, the floral disc of lathe directly is clipped on the cylindrical of base, make so radially that clamping force becomes axial friction, the problem of being out of shape when having solved the turning of steam turbine thin wall shaft base part.
Claims (2)
1, a kind of turbine shaft class thin-wall part turns round with clamping silently, and it is made up of two semi-ring pressing plates (1), base (2) and housing screw (3); It is characterized in that two semi-ring pressing plates (1) are symmetrical arranged Circular Plate of composition, Circular Plate is packed on the base (2), and semi-ring pressing plate (1) is provided with screw (1-1), and housing screw (3) is installed in the screw (1-1).
2, turbine shaft class thin-wall part revolution according to claim 1 with clamping silently is characterized in that base (2) is an annular, and be provided with positioning spigot (2-1) on base (2).
