Abstract

The invention discloses High Precision Central positioning tool, including positioning core axle and tapered sleeve mandrel, the positioning core axle is coaxially embedded in tapered sleeve mandrel and location fit, between the tapered sleeve mandrel and positioning core axle, same section is angularly provided with multiple locking balls, and the locking ball is coordinated using zero-clearance with tapered sleeve mandrel.It is an advantage of the invention that：Locking ball and tapered sleeve mandrel blind-mate, it is ensured that locking ball activity is flexibly；Tapered sleeve mandrel and the location fit that positioning core axle is positioned using taper and end face is positioned, it is ensured that the repetitive positioning accuracy of the frock；O-ring can effectively prevent the entrance of iron filings, it is ensured that the rotation of locking ball is flexible.

Description

High Precision Central positioning tool
Technical field
A kind of the present invention relates to positioning tool, more particularly to High Precision Central positioning tool.
Background technology
Original processing A4V series housing large end face is positioned using optical axis, and optical axis positions repetitive positioning accuracy than relatively low（0.03- Between 0.05）, and dismounting is relatively difficult, causes the housing bearing for processing larger with the coaxiality deviation of bonnet installing hole （More than 0.05）.
Therefore, it is badly in need of a kind of improved technology to solve this problem in the presence of prior art.
Content of the invention
The present invention provides a kind of High Precision Central positioning tool.
The technical solution used in the present invention is：
High Precision Central positioning tool, including positioning core axle and tapered sleeve mandrel, the positioning core axle is coaxially embedded in tapered sleeve The interior simultaneously location fit of mandrel, between the tapered sleeve mandrel and positioning core axle, same section is angularly provided with multiple locking balls, institute State locking ball to coordinate using zero-clearance with tapered sleeve mandrel.
O-ring is provided between the tapered sleeve mandrel and positioning core axle.
The quantity of the locking ball is 10-15.
It is an advantage of the invention that：Locking ball and tapered sleeve mandrel blind-mate, it is ensured that locking ball activity is flexibly；Cone Set mandrel and the location fit that positioning core axle is positioned using taper and end face is positioned, it is ensured that the repetitive positioning accuracy of the frock；O Shape circle can effectively prevent the entrance of iron filings, it is ensured that the rotation of locking ball is flexible.
Description of the drawings
With reference to the accompanying drawings and detailed description the present invention is described in further detail.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the sectional view of A-A in Fig. 1 of the present invention.
Wherein：1st, positioning core axle, 2, tapered sleeve mandrel, 3, O-ring, 4, locking ball.
Specific embodiment
As illustrated in fig. 1 and 2, High Precision Central positioning tool of the invention, including positioning core axle 1 and tapered sleeve mandrel 2, described Positioning core axle 1 is coaxially embedded in tapered sleeve mandrel 2 and location fit, it is ensured that the repetitive positioning accuracy of the frock, the tapered sleeve Between mandrel 2 and positioning core axle 1, same section is angularly provided with 12 locking balls 4, the locking ball 4 and tapered sleeve mandrel 2 are coordinated using zero-clearance, it is ensured that 4 activity of locking ball flexibly, is provided with O-ring 3 between the tapered sleeve mandrel 2 and positioning core axle 1, The entrance of iron filings is effectively prevented, it is ensured that the rotation of locking ball 4 is flexible.
