It controls combined machine to widely apply, to we provide a new solution routes.
The conventional clamp majority of conventional machine tool adapted originally is a set of fixture of a procedure, therefore the positioning and compression provided
Position it is more, as long as positioning with compress element be non-processing surface.But it is more to complete the processing of product needs
Procedure is completed, and the positioning datum of every procedure and machining benchmark are difficult unification, cause the Datum transfer larger；It is more
Process processing needs multiple sets of fixtures just to assist producing, cause in this way it is too long when beam worker keep efficiency relatively low, multiple sets of fixtures
Also relatively high economy is bad for cost.
With the development of numerically-controlled machine tool, various multi-function peripheral beds are widely applied.As turnning and milling combined numerically controlled machine is exactly
One is typical.This kind of lathe usually can a sequence complete 70%-100% processing；And it is overlapped design basis with machining benchmark, it mentions
High machining accuracy.But with the application of all kinds of advanced lathes, conventional fixture cannot be exactly matched.It to be processed in a sequence
More features, it is desirable to which the surface of processed product will begin completely, not allow to arrange pressing plate, this would have to fixed with inner hole
Position simultaneously clamps on.
Summary of the invention
In view of the problems of the existing technology, the present invention proposes a kind of inner hole machinery tensioning device, and spindle flange is according to machine
The connecting interface design of bed main shaft；By the special-shaped product clamping with hole characteristic on the tight device of inner hole mechanical expanding, locking nut
On mandrel；Nut lock clamp force, which is transmitted to tensioner, makes tensioner compressive deformation to radial tensioner；Tensioner inner hole and outer circle
Precision is had, thus by product orientation tensioner on device.
The technical solution of the present invention is as follows:
A kind of inner hole machinery tensioning device, including spindle flange 1, tension mandrel 2, end face positioning sleeve 3, tensioner 4, guiding

Cylinder head bolt c11；
The tension mandrel 2 is Pyatyi multi-diameter shaft, and second level ladder shaft diameter is maximum, and level V ladder shaft diameter is minimum,
First order multi-diameter shaft external cylindrical surface and shaft shoulder end face and spindle flange 1 cooperate, and pass through interior six point cylindrical head bolt b10 and method of principal axis
Blue 1 one end connection；1 other end of spindle flange is positioned at machine tool chief axis inner hole, is connected by interior six point cylindrical head bolt a9 and lathe
It connects；3 sets of end face positioning sleeve on the third level multi-diameter shaft of tension mandrel 2, lower end surface by interior six point cylindrical head bolt c11 with rise
The shaft shoulder connection of tight mandrel 2, end face of the upper surface for product 12 position；
The tensioner 4, spacer 6, guiding tensioner 5, gasket 7 and locking nut 8 are sequentially sleeved in the 5th of tension mandrel 5
On grade multi-diameter shaft；Tensioner 4 with guiding 5 material of tensioner it is identical, be spring steel material, be in thin-walled groove structure, inner hole with
Tension mandrel 2 cooperates, and middle part outside diameter Φ D2 is depending on the hole size of different product 12, in the case where applying pressure
Expanding force is generated to product 12 by micro-deformation；It is Φ D2 size that the guiding tensioner 5, which has an end face outside diameter, is played
Guiding role；6 inner hole of spacer and tension mandrel 2 cooperate, and excircle dimension is less than 12 hole size of product, and spacer 6 is for adapting to not
Length with product 12 changes；Gasket 7 is for being isolated guiding tensioner 5 and locking nut 8, in order to avoid damage guiding tensioner 5；Lock
Tight nut 8 is threadedly coupled with tension mandrel 2, and composition screw thread pair provides pressure, realizes the compression and positioning of product 12.
The end face positioning sleeve 3 is different according to the material of product to be processed, selects different material and heat treatment mode.
Beneficial effects of the present invention:
It is that positioning clamps element with hole characteristic, positions and compress while realizing the special-shaped product with hole characteristic, essence
It determines position, reliable clamping, and machined surface is completely open, greatly improves a sequence working modulus；Avoid the base of multistage manufacturing processes
Quasi- conversion, realizes being overlapped for design basis and machining benchmark, improves machining accuracy.
