Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing.
The processing clamping and processing method of the weak hard parts of a kind of thin-walled of the invention, including following content: work is used
Fill clamping parts.
Tooling includes swollen tire 4, expansion bolt 5.
It is blind hole that top inside swollen tire, which has bellmouth, and the center of bellmouth has tapped through hole；Side line is cut on swollen tire
6 radial slots of wide 0.5 dimensional units are processed, are located at circumference symmetrical 6, expansion bolt 2 includes falling down to be followed successively by end from above
Face, nut and thread segment；It is on the outside of nut round table surface (taper cambered surface), it is identical as taper pore size on the inside of swollen tire.Work as expanding screw
After mother is screwed into swollen tire interior tapered hole, after being adjacent to nut periphery and swollen tire inner hole, swollen tire is propped up, and realizes that part clamps.
The tapped through hole of the thread segment of expansion bolt 2 and swollen tire cooperates.
It is stepped cylindrical outside swollen tire, the outside cylinder of minor diameter is processed in advance according to the hole size of part, small straight
Diameter cylinder is for being packed into inner bore of part, as working region 2；Cylinder with large diameter is for being loaded, as collet region 1, minor diameter
Step end face between cylinder and cylinder with large diameter is as datum plane 3.
Part first completes finishing of internal diameter after getting blank, and expansion bolt is unclamped, and inner hole clamping tightens expanding screw
Bolt, stretching inner hole realize that part stablizes clamping；Furthermore swollen tire end face degree 0.02 perpendicular to the axis, passes through part bottom surface and swollen tire end
Face contact gapless guarantees the verticality requirement of part bottom surface and inner hole.
The method for using the clamping of tooling to process part is (part is by taking schematic construction as an example):
First: machining blanks: requiring, outer circle three-jaw clamping, planar end surface according to product parts structure size, and vehicle inner hole arrives
0 dimensional units of size ф 14+0.1 guarantee inner hole and plane perpendicular degree 0.03, inner bore surface roughness 1.6；Clamping is reversed end for end, is put down
End face guarantees 15 dimensional units of overall length, at this point, there are machining allowance for end face.The state is that tooling requires process blank to reach shape
State.
Second: using the three-jaw clamping lathe clamping tooling swollen tire collet region 1, swollen tire working region 2 rushes outer placement, will
Part is covered in swollen tire working region 2, and part bottom surface is adjacent to tooling datum plane 3, since 2 diameter of work status region is smaller,
It is convenient for mounting and clamping, it is contacted by tooling bottom surface with the machined datum level 1 of part and guarantees that part inside and outside circle is wanted with 1 verticality of datum level
It asks.
Third: being screwed into swollen tire for expansion bolt and correspond in threaded hole, is contacted with swollen tire so that swollen by expansion bolt side
Tire stretching accessory inner surface, realizes the reliable location of part.
4th: when renewal part, only by expansion bolt is screwed out swollen tire need to being loosened, can easily to remove part complete
At replacement.
