Abstract
The invention provides a fixture structure for machining a large thin-wall annular part, which can solve the problem that fixture structure of a traditional annular part is easy to deform after clamping the thin-wall annular part . The fixture structure for machining the large thin-wall annular part can effectively clamp parts and also ensure the machining quality and precision of the parts. The fixture structure for machining the large thin-wall annular part comprises a fixture body and is characterized in that the center of the fixture body is provided with a circular boss, the fixture body is provided with a pressing plate along the circumference, and the pressing plate is sleeved on the upper surface of an annular part to be machined outside the circular boss from the upper part in a compacting manner.
Description
Technical field
The present invention relates to large-sized annular part processing frock field, be specially the 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, wall thickness only is 7.8mm, traditional ring-shaped work pieces is when carrying out surperficial NC Milling, how to clamp part jointly by 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 easily to make part generation distortion radially, thereby influence part processing quality and machining accuracy for thin-walled parts.
Summary of the invention
At the problems referred to above, the invention provides the 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: described clamp body is central to be round boss, and described clamp body is equipped with pressing plate along circumference, and pressing plate is loaded on the ring-shaped work pieces upper surface described to be processed of described round boss outside from the top clamping sleeve.
It is further characterized in that: pad is equipped with brass ingot and fixes by screw and described clamp body between described pressing plate and the described ring-shaped work pieces to be processed; Described pressing plate is provided with six, and described six block pressur plates are along the installation that evenly distributes of described clamp body circumference.
A kind of clamp structure that is used for the processing of large thin-wall ring-shaped work pieces of the present invention, it is simple in structure, by clamp body surface round boss and circumferential pressing plate, ring-shaped work pieces is clamped simultaneously at inner peripheral surface and upper surface, 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 schematic diagram of Fig. 1 processing parts of the present invention;
Fig. 2 is a kind of plug clamp structure schematic diagram that is used for large-scale cylindrical part processing of the present invention.
The specific embodiment
See Fig. 1, Fig. 2, it comprises clamp body 1 structure of the present invention, 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 by 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.
