Abstract
The utility model discloses a kind of thin-walled rotary part processing expansion set, this thin-walled rotary part processing expansion set comprises expansion core, opening expansion set, threaded pressure ring, lock-screw; Described expansion core tapering adopts 5-15 degree, opening expansion set endoporus coordinates with expansion core, threaded pressure ring screws and is arranged on opening expansion set front end, and opening expansion set and threaded pressure ring are provided with the screwed hole installing lock-screw, and the two ends of lock-screw are left-handed and right-handed thread respectively.Lock-screw two ends of the present utility model are left-handed and right-handed thread respectively, turn lock-screw, threaded pressure ring is moved axially, and drive opening expansion set moves axially by threaded pressure ring, because opening expansion set and expansion core are taper fit, moving axially of expansion set will make the external diameter size of expansion set change, structure is simple, and location, repetitive positioning accuracy are high, and expansive force is large, be convenient to dismounting, minimum to machining interference.
Description
Technical field
The utility model belongs to machining apparatus field, particularly relates to a kind of thin-walled rotary part processing expansion set.
Background technology
Advanced aero engine is because the extreme requirement to loss of weight, and structural design becomes increasingly complex, and brings great challenge to processing, particularly the Vehicle Processing of thin-walled rotary part, needs to utilize expansion set to carry out swelling location to endoporus.
Tradition expansion set because of retaining mechanism longer, dismantle extremely inconvenient, and part normal processing technology route may be affected, greatly have impact on production efficiency.
Utility model content
The object of the utility model embodiment is to provide a kind of thin-walled rotary part processing expansion set, be intended to solve traditional expansion set because of retaining mechanism longer, dismounting is inconvenient, and may affect part normal processing technology route, affects the problem of production efficiency.
The utility model is that a kind of thin-walled rotary part processing expansion set realized like this comprises expansion core, opening expansion set, threaded pressure ring, lock-screw; Described expansion core tapering adopts 5-15 degree, opening expansion set endoporus coordinates with expansion core, threaded pressure ring screws and is arranged on opening expansion set front end, and opening expansion set and threaded pressure ring are provided with the screwed hole installing lock-screw, and the two ends of lock-screw are left-handed and right-handed thread respectively.
Further, the external diameter of threaded pressure ring is identical with treating the workpiece external diameter of swelling.
Further, material selection No. 45 steel of expansion core and opening expansion set or steel alloy, modified 35-45HRC.
Further, threaded pressure ring adopts with expansion set and is threaded, pitch 2-4 millimeter, threaded pressure ring axial width 5-15 millimeter.
Further, lock-screw coordinates with expansion core and threaded pressure ring respectively, is of a size of M6-M12.
Lock-screw two ends of the present utility model are left-handed and right-handed thread respectively, turn lock-screw, threaded pressure ring is moved axially, and drive opening expansion set moves axially by threaded pressure ring, because opening expansion set and expansion core are taper fit, moving axially of expansion set will make the external diameter size of expansion set change, structure is simple, and location, repetitive positioning accuracy are high, and expansive force is large, be convenient to dismounting, minimum to machining interference.
