Abstract
The utility model provides a fixture structure for processing annular and special-shaped parts, which can guarantee reliable and stable clamping during numerical-control milling of parts, and guarantees that the parts are not easy to deform. The fixture structure comprises a substrate, and is characterized in that the substrate is provided with a circular groove, an axial positioning hole is arranged at the central bottom of the circular groove, a positioning clamp is disposed in the axial positioning hole, and a side surface press plate positioning mechanism is disposed on an upper peripheral surface of the substrate.
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 annular special-shaped part processing.
Background technology
A kind of annular special-shaped part that is used for aero-engine, its structure is seen illustrated in figures 1 and 2, its circumferential surface on annular element has the spline 7 of odd number five equilibrium, mostly the processing of spline in the past is to adopt broaching machine to process with broaching tool, but because this ring-shaped work pieces wall thickness, thinnest part is 4.5mm only, and to process its cutting stress big so adopt in the past broaching tool to carry out spline, easily causes the distortion of workpiece.In order to address the above problem, now use the spline processing that CNC milling machine carries out this part instead, because this annular special-shaped part cross section complexity adopts common CNC milling machine anchor clamps, can't carry out accurate clamping location to part, influence the location processing of part.
Summary of the invention
At the problems referred to above, the utility model provides a kind of clamp structure that is used for the processing of annular special-shaped part, and clamping was reliable and stable when it can guarantee that part by numerical control mills processing, and guaranteed that part is not yielding.
Its technical scheme is such, it comprises matrix, it is characterized in that: described matrix has circular groove, and described circular groove center bottom has the axial location hole, described axial location is provided with the location fastener in the hole, and circumferential surface is provided with side pressing plate detent mechanism on the described matrix.
It is further characterized in that: described part side pressing plate detent mechanism is provided with three, and described three part side pressing plate detent mechanisms are along the installation that evenly distributes of circumferential surface on the matrix; Described side pressing plate detent mechanism comprises the side pressing plate, and the working face that compresses of described side pressing plate is the conical surface, the taper inner recess coupling of the described conical surface and annular special-shaped part outer peripheral face to be processed.
A kind of clamp structure that is used for annular special-shaped part processing of the present utility model, its location fastener suffers that part side pressing plate detent mechanism is fixedly clamped to part in the interior ring side of part and the side surface of part jointly, its clamping is reliable, the side pressing plate of part side pressing plate detent mechanism cooperates with the outer weekly form recess of part, part is not yielding in clamping process, has guaranteed the crudy and the precision of part.
