Description
Technical field
This utility model belongs to mechanical manufacturing field, is specifically related to a kind of novel Internal hole positioning, Tensioning structure.
Background technology
As mechanical processing industry, it is frequently encountered some disk-like accessories, needs on the basis of machined endoporus,
Location processing other to be processed, in order to improve working (machining) efficiency, it is to avoid before processing, pieces is corrected, so often
Can design, make a kind of with Internal hole positioning, the ringfeder of tensioner, rise cored structure；Therefore a kind of positioning accurate of research and development
Really, stablize, tensioner is firm, efficient, quick, improve efficiency and the new type of bore locating tensioning structure of precision
There is very much Practical significance.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of registration, steady
Determine, tensioner is firm, efficient, quick, improve the new type of bore location of efficiency and precision, Tensioning structure.
The purpose of this utility model is achieved in that a kind of novel Internal hole positioning, Tensioning structure, its bag
Including nut, described nut is that clamp nut takeed on by band, and the outside of described band shoulder clamp nut is provided with ringfeder,
Being provided with groove on the outer wall of described ringfeder, the shoulder of described band shoulder clamp nut is arranged on the sky of ringfeder
Intracavity, the lower surface of the shoulder of described band shoulder clamp nut is provided with thrust ball bearing, described thrust ball
Bearing is also disposed in the cavity of ringfeder, and the mandrel that rises is fixed in being internally provided with of described ringfeder, and described rises
The outside of set is provided with workpiece to be processed, and the bottom of described workpiece to be processed is provided with end face location and supports seat.
Described groove is loop configuration.
The number of described groove is at least 3.
Reading aloud in the inside of described groove tightly has rubber band.
The inner conical surface of described ringfeder is completely the same with the angle of the male cone (strobilus masculinus) of the fixing mandrel that rises.
The outer wall of described ringfeder is cylindrical surface structure.
After the final machine-shaping of described ringfeder, according to its face of cylinder diameter on cutting on line, vertically
Line uniformly cuts.
The beneficial effects of the utility model: this utility model is because of the advance of its structure, and this kind of structure is the most not
Positioning precision and expanding force is affected by the tolerance values in hole, part to be processed location, because the footpath of ringfeder outer wall
Increase, therefore along with the inner conical surface of ringfeder, the increase of the male cone (strobilus masculinus) angle of the fixing mandrel that rises to contraction scope
The most not affecting use when positioning hole dimension scattered error and being bigger, simultaneously because of ringfeder equal mark lobe, each lobe of ringfeder is radially
During spreading, external cylindrical surface does not haves tapering, and the goodness of fit of the inner cylinder face in its outer wall and hole to be positioned is all the time
For maximum, it is ensured that positioning precision and expanding force；Band shoulder clamp nut, in rundown process, presses and pushes away
The end face of power ball bearing, this pretightning force is transferred to novel ringfeder rear end face, novel ringfeder by thrust ball bearing
Moving down along the fixing mandrel male cone (strobilus masculinus) that rises under responsive to axial force, in folding process, novel ringfeder inner conical surface can be solid
Surely rise under mandrel male cone (strobilus masculinus) counteracting force so that ringfeder wall radially spreading, reach expansion sleeve on ringfeder outer wall
Part, for processing other to be processed；During this, band shoulder clamp nut in screwing operations, its axle
Pass to ringfeder to pretightning force by thrust ball bearing, so ringfeder is only by axial compressive force, there is no circumference
Frictional force, it is simple to screw, unlike traditional ringfeder, rise cored structure, and clamp nut directly compresses ringfeder, no
Only producing bigger frictional force because of its contact surface, it is painstaking to compress, and more or unclamps wink because of ringfeder before tensioner endoporus
Between, can there is minor rotation, increase under frictional force effect in ringfeder outer wall and hole to be positioned inner cylinder face
The abrasion of ringfeder outer wall, decreases service life, reduces positioning precision.
