Description
Technical field
The present invention relates to a kind of auxiliary process technical field of spoke wheel type inlet casing part, more particularly to one kind can be automatic
The resilient supporting unit of centering.
Background technology
Aero-engine inlet casing part uses spoke wheel type welding structure, i.e. an inner ring passes through certain with an outer shroud
The hollow support plate solder joint of quantity is integral, and one end of support plate is connected in the inner wall of outer shroud, and the other end is connected in the outer wall of inner ring.Its
Axial design benchmark is one end end face of outer shroud, and radial reference is the gyration central axis of inner ring inner wall.Outer shroud outer wall is to add
Work area domain, outer shroud inner wall are irregular cylindrical surfaces.Common localization method is used before, and fixture is first installed on to the work of lathe
Make on platform, be placed on by one end end face of machine casing outer shroud on the installation base surface of fixture with the axial benchmark of positioning, Zhi Houxu
Using instruction table look-up inner ring inner wall circumference bounce variable quantity, with reference to dial gauge numerical value by the method movable clamp of percussion,
The revolution axle center of part is determined by adjusting repeatedly, after centering, whole operation process is cumbersome, and work efficiency is relatively low, Er Qieding
Position low precision.The poor structure rigidity of inlet casing, during outer shroud outer wall is processed, outer shroud easily by cutting force influenced produce by
Compel vibration, selection cutting parameter is bigger, and cutting force is bigger, and the vibration that inlet casing outer shroud produces is more obvious, not only processing quality
Difference, and accelerate the loss of process tool.
The content of the invention
In order to solve the above technical problems, the object of the present invention is to provide one kind can self centering resilient supporting unit, tool
Body technique scheme is as follows：
One kind can self centering resilient supporting unit, including base, locating ring, compact heap, support base, O-ring, core
Axis, bearing, centrum, backing pin, compression spring, expansion block, gland, adjusting nut and hanging ring；
The locating ring is bolted on base, and installation base surface of the locating ring end face as clamping parts；
The pressing device is made of pressing plate, stud, supporting pin and nut；
The lower end of part is installed side by pressing device to be fixed on base；
The support base is bolted on base, and upper outside is equipped with annular recess；
The O-ring is embedded in the annular recess of support base, the part fitting part outer shroud inner wall exposed；
The mandrel is fixed on the center of base, and portion's installation fixing stud；
The bearing is arranged on the outside of mandrel, upper surface installation fix stopper, and is fixed on base；
The cone is socketed in mandrel top, and cone endoporus with mandrel is cylindrical fits closely；
The expansion block is installed on holder top inner wall close to cone male cone (strobilus masculinus), ring inner surface in external cylindrical surface swelling part；
The outer surface of cone is bonded with expansion block；

Cone, compression spring and expansion block are fixed on bearing by the gland by bolt；
The adjusting nut is arranged on the fixing stud of mandrel, can flex outward expansion block for tightening adjusting nut；
Described hanging ring one end is threadedly secured on base, and the other end is used to connect suspender.
Described one kind can self centering resilient supporting unit, its preferred solution for the base external cylindrical surface be equipped with look for
Positive annulus.
Described one kind can self centering resilient supporting unit, its preferred solution is equipped with 8 loss of weight sectors for base
Loss of weight mouth.
Described one kind can self centering resilient supporting unit, its preferred solution is additionally provided between the pressing device
Basal plane is measured, is fixed on base, for measuring the part height after processing.
Beneficial effects of the present invention：Technical scheme overcomes that existing localization method clamping speed is slow, positioning accuracy
Difference, be unable to the problem of vibration damping.Can effectively be lifted parts fixation speed, precise positioning and can effectively suppress cut force vibration carry
High technology rigidity, and material removing rate is improved, it can be achieved that producing necessary ancillary fabrication method in enormous quantities.Before using common fixed
The position each clamping parts of method are required for operator's Manual alignment, adjustment part revolution axle center, generally require 20 to 30 minutes
Time, and common localization method can not suppress cutting vibration, can only reduce cutting force shadow by reducing the method for cutting parameter
Ring, general process time needs 20 to 25 hours, and processing efficiency is very low, and technical scheme can self centering bullet
Property support technology scheme clamping, time for positioning a part be no more than 5 minutes, while can realize high material removing rate, process
Time be usually no more than 12 it is small when.
