When in order to solve using "V"-block measurement odd number gear spline excircle dimension, there are "V"-block positioning inconvenience, and lead
The technical problem for causing measurement result inaccuracy, the present invention provides a kind of odd number gear spline excircle dimensions to measure cubing.
The technical solution of the invention is as follows:
A kind of odd number gear spline excircle dimension measurement cubing, including "V"-block and amesdial, are characterized in that also
Including locating piece, compressed spring and gland.
The locating piece is multi-diameter shaft, and gauge head mistake compatible with the gauge head outer diameter of amesdial is arranged in the big end of locating piece
Hole, small end setting can gap compatible with the spline tooth of measured piece.
Counterbore is arranged in the small end center of the "V"-block, and the small end of locating piece is used to position after passing through counterbore lower part aperture
The spline tooth of measured piece highest order, big end are placed in the macropore of counterbore top；Gland, gland is arranged in the small end of the "V"-block
Center is equipped with through-hole, and the gauge head of amesdial (4) sequentially passes through gland (5), "V"-block (1) and locating piece (2) afterwards and measured piece
(6) spline tooth of highest order is in contact；Compressed spring is set between gland and the big end end face of locating piece.
Further, in order to which structure is simpler, the quantity of the compressed spring is one, is coaxially disposed with locating piece 2.
Further, more evenly for stress, the quantity of the compressed spring is two, and two compressed springs are relative to fixed
The axisymmetrical setting of position block.
Further, more convenient in order to install, the gland is connected by screw in the "V"-block.
Further, in order to which compressed spring can be limited preferably, the big end end face of the locating piece is equipped with groove, recessed
The diameter of slot is adapted with the outer diameter of the compressed spring.
The beneficial effect of the present invention compared with prior art is:
1, the present invention adds locating piece, compressed spring and gland in existing "V"-block, measures odd number gear spline outer circle ruler
When very little, "V"-block can be positioned quickly, and measurement efficiency is high.
2, two compressed springs in the present invention are arranged relative to the axisymmetrical of locating piece, and compressed spring stress is more equal
It is even.
3, the gland in the present invention is connected by screw in the upper of the "V"-block, and installation is more convenient.
4, the big end end face of locating piece is equipped with groove in the present invention, and the diameter of groove is mutually fitted with the outer diameter of compressed spring
Match, compressed spring can be limited preferably.
