Description
Technical field
The invention belongs to a kind of apparatus for correcting, and in particular to a kind of ultra-thin-wall cylinder class location of workpiece degree apparatus for correcting.
Background technique
Ultra-thin-wall cylinder class workpiece would generally be in irregular ellipticity, ultra-thin-wall cylinder since its wall is thin in its natural state
Class workpiece is in there is clampings in machining field many uncertain factors such as difficult, machining accuracy is difficult to ensure.
In the middle part of ultra-thin-wall cylinder class workpiece after processing technology groove, respective positions degree floating in groove two sides is very big, and work
The position degree variation of part entirety also very greatly, cannot meet the technological requirements substantially.
So-called position degree refers to that the axis of a body or central plane allow self-position to change the i.e. body of Fan Wei ﹐
The permission mobility scale of the physical location relative theory position of axis or central plane.The meaning for defining axis or central surface exists
In the influence for avoiding feature dimension.
Position degree includes position degree, the position degree of line and the position degree in face of point.
Ultra-thin-wall cylinder class workpiece is corrected means and is not particularly suited for ultra-thin-wall due to its own particularity, conventional position degree
The position degree of class workpiece is corrected, moreover, there is no the correction means and correcting device of this aspect at present.
Summary of the invention
The present invention proposes that the purpose is to provide a kind of ultra-thin-wall cylinder class workpiece position in order to solve the problems existing in the prior art
Degree of setting apparatus for correcting.
The technical scheme is that a kind of ultra-thin-wall cylinder class location of workpiece degree apparatus for correcting, including tighten bolt, pressure
The bottom of device is arranged in ring, mandrel, upper core model, lower core model and pedestal, pedestal, is equipped with mandrel in the upper end of pedestal, on
Core model, lower core model are separately mounted to the upper/lower terminal of mandrel outer circle, and centre is separated by the collar of mandrel, and workpiece upper section is mounted on
The upper/lower terminal of the outer circle of upper core model, workpiece lower section are mounted on the upper/lower terminal of the outer circle of core model, lower core model, workpiece it is recessed
Slot and collar are corresponding, tighten bolt and are screwed into the internal thread hole of mandrel across pressure ring, the nut for tightening bolt fixes pressure ring
On upper core model.
The section of the pedestal is the T-shape structure for having centre bore.
The mandrel is have internal thread hole columnar structured, forms collar among mandrel outer wall axial direction.
The upper core model, lower core model are made of same material, and its coefficient of expansion is greater than the coefficient of expansion of workpiece.
Ultra-thin-wall cylinder class location of workpiece degree apparatus for correcting of the invention, position can not be corrected by solving ultra-thin-wall cylinder class workpiece
The problem of spending improves machining accuracy and the efficiency of loading and unloading, provides effective solution for the processing of ultra-thin-wall cylinder class batch workpieceization
Method.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Wherein:
1 tightens 2 pressure ring of bolt
Core model on 3 mandrels 4
5 lower 6 pedestals of core model
7 collar, 8 workpiece
9 workpiece upper section, 10 workpiece lower section
11 grooves
Specific embodiment
Hereinafter, referring to drawings and examples, the present invention is described in detail:
As shown in Figure 1, a kind of ultra-thin-wall cylinder class location of workpiece degree apparatus for correcting, including pedestal 6, tighten bolt 1, pressure ring 2,
Mandrel 3, upper core model 4, lower core model 5.The section of pedestal 6 is the T-shape structure for having centre bore, and the bottom of device is arranged in,
The upper end of pedestal 6 is equipped with mandrel 3, and mandrel 3 is to have the columnar structured of internal thread hole, is formed among 3 outer wall axial direction of mandrel
Collar 7.
Upper core model 4, lower core model 5 are separately mounted to the upper/lower terminal of 3 outer circle of mandrel, and centre is separated by the collar 7 of mandrel 3.
Workpiece upper section 9 is mounted on the upper/lower terminal of the outer circle of core model 4, and workpiece lower section 10 is mounted on the outer circle of core model 4, lower core model 5
Upper/lower terminal, the groove 11 and collar 7 of workpiece to be processed 8 are corresponding.
It tightens bolt 1 to be screwed into the internal thread hole of mandrel 3 across pressure ring 2, the nut for tightening bolt 1 is fixed by pressure ring 2
On upper core model 4.The section for tightening bolt 1 is " work " the type structure for having centre bore.
The upper core model 4, lower core model 5 are made of same material, and its coefficient of expansion is greater than the coefficient of expansion of workpiece 8.
Application method of the invention: after workpiece is mounted on ultra-thin-wall cylinder class location of workpiece degree apparatus for correcting, it is put into vacuum
In glowing furnace, be heated heat preservation, upper core model 4, lower core model 5 thermal expansion coefficient be sufficiently more than the thermal expansion coefficient of workpiece 8, on
Core model 4, lower core model 5 are respectively by the 8 swollen circle of upper and lower ends swelling of workpiece, after held for some time, upper core model 4, lower core model 5 and workpiece
8 is cooling with vacuum quencher, then takes out workpiece from device, the concentricity of workpiece upper and lower ends is realized with this, is reached
The correction of ultra-thin-wall cylinder class location of workpiece degree.
Ultra-thin-wall cylinder class location of workpiece degree apparatus for correcting of the invention, position can not be corrected by solving ultra-thin-wall cylinder class workpiece
The problem of spending (concentricity), improves machining accuracy and the efficiency of loading and unloading, has provided for the processing of ultra-thin-wall cylinder class batch workpieceization
The solution of effect.
