The using method of this centring means for support shaft class inner bore of part is as follows：
Step 1：First collet 401 is put into the left side so as to location mandril 1 middle part from the left end of location mandril 1
End face is fitted；First conical ring 3 is also put into from the left end of location mandril 1, makes the outer cone ring of the first conical ring 3 right-hand member load the first bullet
In the internal taper hole of property chuck 401；Again the 3rd collet 403 is put into from the left end of location mandril 1, by the second conical ring 2 from
The left end of location mandril 1 is put into, and so that the outer cone ring of the second conical ring 2 right-hand member is loaded in the internal taper hole of the 3rd collet 403；Then
First nut 7 is screwed in the screw thread of location mandril 1 using box spanner assembly 10, gently tightens the first nut 7, make to assemble
The first good conical ring 3 and the male cone (strobilus masculinus) inner cone with the first collet 401 and the 3rd collet 403 respectively of the second conical ring 2
Hole contacts.
It should be noted that the present embodiment is divided into three elastic parts, respectively first collet the 401, second elasticity
Chuck 402 and the 3rd collet 403, carry out tensioner of feeling relieved.Also according to the difference requirement of processed axial workpiece, select two
Elastic part, the respectively first collet 401 and the second collet 402, carry out tensioner of feeling relieved.
Step 2：Second collet 402 is put into the right side so as to location mandril 1 middle part from the right-hand member of location mandril 1
End face is fitted, and so that the inner conical surface of the second collet 402 is contacted with the male cone (strobilus masculinus) of location mandril 1；Then by bushing 5 from locating core
The right-hand member of rod 1 is put into, and is connected by the elongate slots of bushing 5 and location mandril 1 with pin 14, makes bushing 5 in locating core
Can axially move on rod 1.
Step 3：The said apparatus assembling are loaded from the left end of axial workpiece, and by gland 6 from the right side of axial workpiece
End loads axial workpiece it is ensured that the axle of the endoporus of gland 6 and location mandril 1 coordinates and gap is not more than 0.01, in location mandril 1
Right-hand member screw in the second nut 902, pre-pressing.
Step 4：Positioning bushing 8 is loaded axial workpiece it is ensured that positioning the endoporus of bushing 8 and determining from the left end of axial workpiece
The axle of position plug 1 coordinates and gap is not more than 0.01, screws in the 3rd nut 901, complete this centring means and exist on location mandril 1
Assembling in axial workpiece.
Step 5：Pre-screwing the 3rd nut 901 makes step end face and the laminating of axial workpiece left side of positioning bushing 8；Then
Tighten the second nut 902 again, by the male cone (strobilus masculinus) of the outer cone ring of the first conical ring 3, the second conical ring 2 and location mandril 1 middle part right side,
Fit with the inner conical surface of the internal taper hole of the first collet 401, the 3rd collet 403 and the second collet 402 respectively, lead to
Cross the screw thread that the second nut 902 screws in location mandril 1, make the first collet 401, the second collet 402 and the vertically
Three collet 403 spreading reaches and contacts with axial workpiece and tensioner, meet thin-wall long and thin type axial workpiece endoporus many
Section elastic centering requires.
Step 6：. after the completion of Machining of Shaft-type Parts, unclamp the 3rd nut 901 and second nut 902 at left and right end, it is fixed to take out
First nut 7 is unscrewed from location mandril 1 using box spanner assembly 10 and is taken out, using 2 spiral shells by position bushing 8 and gland 6
Nail 13 is screwed into the screw thread in the hole of the second conical ring 2, the second conical ring 2 is taken out from part, afterwards the first conical ring 3, the first elastic clip
The 401, second collet 402, the 3rd collet 403, bushing 5 both can freely take out.
Step 7：The centring means not used time, in order to prevent the deformation of this centring means, collar nut 12 is screwed into locating core
The threaded portion of excellent 1 left or right, vertically hangs.
The utility model provides a kind of centring means for support shaft class inner bore of part, by the 3rd nut at two ends
901 and second nut 902, make the second collet of the first collet 401, the 3rd collet 403 and the right-hand member of left part
402 spreadings, and fit and stretching with axial workpiece, the centering quickly realizing thin-wall long and thin profile shaft class inner bore of part requires.Pass through
Cylindrical grinder main axis, drive this centring means to rotate together with axial workpiece, realize the processing of axial workpiece external diameter.This practicality
New axial workpiece endoporus can be supported, increased the integral rigidity of axial workpiece, meanwhile, improve axial workpiece
Machining accuracy, axial workpiece is quick detachable.
