Part has many advantages, such as that light-weight, intensity is high, material saves, stress is good, geometric modeling is smooth, easy to process.
Annular thin wall part is because its thickness ratio is relatively thin, diametrical rigidity deficiency, therefore difficulty of processing is larger.Traditional
Processing technique of annular thin wall part is directly to be installed in annular thin wall part on spindle chuck, and resulting problem is：Chuck is determined
Position make annular thin wall part easily deform in the radial direction thereof and process in cause to be become by heat due to the depth of cut is excessive
Shape.In view of the situation, in order to which stationary annular thin-wall part avoids directly radially generating workpiece fastening stress effect, in design ring
It during shape thin-wall part processing tool, is not fixed radially, and uses thin in annular by locking auxiliary mould in annular thin wall part
The axial direction of wall pieces is located, and can be effectively prevented from the workpiece radial dimension generated due to workpiece is clamped stress by claw and be deformed,
Ensure the machining accuracy of annular thin wall part, improve work pieces process qualification rate.
The content of the invention
In view of the deficiency of the prior art, the utility model provides a kind of thin-wall part processing locking device, it is locked
Tight effect is good, convenient and practical, and annular thin wall part radial dimension can be avoided to deform, ensure the machining accuracy of annular thin wall part, carry
High annular thin wall part passing rate of processing.
Technical solution adopted in the utility model is：A kind of thin-wall part processes locking device, including mandrel, locking member and
Pressing plate, the locking member include locking cap and two lock plungers；The cross section of described two lock plungers is trapezoidal, two lockings
Pig gauge lattice are identical, and the trapezoidal upper bottom edge of two lock plungers is in contact, and the locking cap is detachably connected with two lock plunger upper ends,
The mandrel upper surface opens up fluted, described two lock plunger lower ends and groove grafting, and through hole is offered in the middle part of the pressing plate,
The pressing plate is sleeved on by through hole on two lock plungers, and pressing plate is arranged between locking cap and mandrel.
The beneficial effects of the utility model are：
1. the locking member of the utility model and mandrel grafting, annular thin wall part are sleeved on mandrel, pressing plate is by annular thin wall
Part is positioned and locked by locking member, so as to fulfill the locking positioning in the axial direction of annular thin wall part, avoids annular thin wall part footpath
To size distortion, ensure the machining accuracy of annular thin wall part, improve the passing rate of processing of annular thin wall part.
2. two lockings of the utility model locking member fasten and can skid off and slip into out of mandrel groove, convenient for locking member with
The installation and removal of mandrel, it is simple in structure, convenient and practical, locking effect is good.
