Abstract
The utility model provides a fixture structure for processing large-size thin-wall annular parts, which can resolve the problem that after a traditional fixture structure for annular parts clamps thin-wall annular parts, the thin-wall annular parts are easy to deform. The fixture structure not only can effectively clamp the parts, but also can guarantee processing quality and precision of the parts. The fixture structure comprises a fixture body, and is characterized in that a circular boss is arranged at the center of the fixture body, and a press plate is mounted on the fixture body along the periphery of the fixture body, and is sleeved on the upper surface of an annular part to be processed on the outside of the circular boss in a pressed manner from the upper portion of the annular part to be processed.
Description
Technical field
The utility model relates to large-sized annular part processing frock field, is specially a kind of clamp structure that is used for the processing of large thin-wall ring-shaped work pieces.
Background technology
A kind of large-sized annular thin-walled parts that is used for aero-engine; Its part section structure is seen Fig. 1, and wall thickness is merely 7.8mm, and traditional ring-shaped work pieces is when carrying out surperficial NC Milling; How to clamp part jointly through ring-shaped work pieces inner radial chuck and outer clamp body; But, adopt the above-mentioned traditional radially chuck and the clamp structure of outer clamp body structure to be prone to make part to produce distortion radially, thereby influence part processing quality and machining accuracy for thin-walled parts.
Summary of the invention
To the problems referred to above; The utility model provides a kind of clamp structure that is used for the processing of large thin-wall ring-shaped work pieces; It can solve the clamp structure that adopts the traditional endless part and clamp the problem that is prone to part deformation behind the circular thin-wall part, can effectively clamp part, can guarantee the crudy and the precision of part again.
Its technical scheme is such; It comprises clamp body; It is characterized in that: said clamp body is central to be round boss, and said clamp body is equipped with pressing plate along circumference, and clamping sleeve is loaded on the outside ring-shaped work pieces upper surface said to be processed of said round boss to pressing plate from top.
It is further characterized in that: pad is equipped with brass ingot and fixes through screw and said clamp body between said pressing plate and the said ring-shaped work pieces to be processed; Said pressing plate is provided with six, and said six block pressur plates are along the installation that evenly distributes of said clamp body circumference.
A kind of clamp structure that is used for the processing of large thin-wall ring-shaped work pieces of the utility model, it is simple in structure, through clamp body surface round boss and circumferential pressing plate; Ring-shaped work pieces is clamped at inner peripheral surface and upper surface simultaneously; Clamp reliably, for face contacts, reduced when clamping impact between its boss and circumferential pressure and the ring-shaped work pieces piece surface; Effectively avoid the metaboly in the process of clamping, guarantee the crudy and the machining accuracy of ring-shaped work pieces; The brass ingot of pad dress between pressing plate and the ring-shaped work pieces to be processed can reduce the compress impact of pressing plate to part in addition, further reduces the distortion in the parts fixation process.
Description of drawings
The cross section structure sketch map of the processing parts of Fig. 1 the utility model;
Fig. 2 is a kind of plug clamp structure sketch map that is used for large-scale cylindrical part processing of the utility model.
The specific embodiment
See Fig. 1, Fig. 2; It comprises clamp body 1 the utility model structure; Clamp body 1 central authorities are provided with round boss 2, and clamp body 1 is equipped with pressing plate 3 along circumference, and ring-shaped work pieces 4 to be processed is set in round boss 2 outsides, pressing plate 3 and compresses ring-shaped work pieces 4 upper surfaces to be processed from top when clamping.Pad is equipped with brass ingot 5 and fixing with clamp body 1 through screw 6 between pressing plate 3 and the ring-shaped work pieces to be processed 4; Pressing plate 3 is provided with six, and six block pressur plates 3 are along the installation that evenly distributes of clamp body 1 circumference.Among Fig. 2,7 is pad.
Claims (3)
1. one kind is used for the clamp structure that the large thin-wall ring-shaped work pieces is processed; It comprises clamp body; It is characterized in that: said clamp body is central to be round boss; Said clamp body is equipped with pressing plate along circumference, and clamping sleeve is loaded on the outside ring-shaped work pieces upper surface said to be processed of said round boss to pressing plate from top.
2. a kind of clamp structure that is used for large thin-wall ring-shaped work pieces processing according to claim 1 is characterized in that: fill up between said pressing plate and the said ring-shaped work pieces to be processed and brass ingot is housed and fixes through screw and said clamp body.
