Abstract
The utility model discloses a clamp for thin-wall shaft parts. The clamp is composed of two semi-ring press plates, a ring-shaped base and pressing screws. The two semi-ring press plates are symmetrically arranged into a ring plate, the ring plate is fixed onto the base through bolts, the semi-ring press plates are provided with screw holes, the pressing screws are mounted inside the screw holes, the base is provided with a positioning locking opening, the pressing ends of the pressing screws are fixedly connected with arc-shaped pressing plates, and the arc-shaped pressing plates adapt to the thickness of the wall of a thin-wall part to be turned in size. The clamp for the thin-wall shaft parts can improve the stability of the thin-wall shaft parts during the turning process.
Description
Technical field
The utility model relates to a kind of axle class centering clamping tool, relates in particular to a kind of fixture for turbine shaft class thin-walled parts.
Background technology
Steam turbine has a lot of axle class thin-walled revolution parts, and its internal diameter is mostly between 200-360mm, and length is greater than 1500mm, and wall thickness is less than 7mm, and after processing, cylindricity should be less than 0.02mm.This class part is in the time of fine turning outer circle, and the improper part that very easily causes of clamping deforms because clamping force is excessive, even assemble silently at thin-wall part endoporus, owing to there being the magnitude of interference, the outer fenestra of pulling down after thin-wall part silently can deform.
In order to address the above problem, following technology is proposed in prior art:
As China Patent No. " 200720117742.8 " discloses a kind of clamping bulkhead for rotation of steam turbine shaft type thin wall parts, its open day is on October 01st, 2008, and clamping is silently made up of two and half ring-shaped pressuring plates, base and housing screw described in its technical scheme; Base is annular, and base is provided with positioning spigot, and two and half ring-shaped pressuring plates are symmetrical arranged a Circular Plate of composition, and Circular Plate is packed on base, and half ring-shaped pressuring plate is provided with screw, and housing screw is arranged in screw.But in actual use, due to the compression end of housing screw and the contact area of thin-walled parts less, cause housing screw less to the pressure of thin-walled parts, when to turning thin-walled parts, thin-walled parts is easily loosening, affects turning effect.
Summary of the invention
The purpose of this utility model is to solve the above-mentioned problems in the prior art, and a kind of fixture for axle class thin-walled parts is provided, and the utility model can improve the stability of thin-walled parts in turning process.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of fixture for axle class thin-walled parts, it is characterized in that: formed by two and half ring-shaped pressuring plates, annular base and housing screw, described two and half ring-shaped pressuring plates are symmetrical arranged and form a Circular Plate, described Circular Plate is bolted on base, on described half ring-shaped pressuring plate, be provided with screw, described housing screw is arranged in screw, on described base, be provided with positioning spigot, the compression end of described housing screw is fixedly connected with pressure strip, described pressure strip is arc, and it is big or small and treat that the wall thickness of turning thin-wall part is suitable.
The radian of described pressure strip is π/6-π/4.
Described pressure strip is threaded with housing screw.
Employing the utility model has the advantage of:
One, in the utility model, compression end at housing screw connects pressure strip, the contact area that is conducive to increase housing screw and treat turning thin-wall part, thereby can increase the pressure of housing screw to part, be conducive to improve the stability of thin-walled parts in turning process, thereby improve the turning effect of part.
Two, in the utility model, the radian of described pressure strip is set to π/6-π/4, makes the stably compressing component of two arc-shaped sides of pressure strip, is conducive to improve turning accuracy.
Three, in the utility model, described pressure strip and housing screw are threaded connection, and this structure is convenient to change pressure strip, by changing the pressure strip of different model, are applicable to compress the part of different size, thereby improve the scope of application of whole fixture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, be labeled as: 1, base, 2, half ring-shaped pressuring plate, 3, housing screw, 4, positioning spigot, 5, pressure strip.
