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 utility model compared with prior art is:
1, the utility model adds locating piece, compressed spring and gland in existing "V"-block, measures outside odd number gear spline
When circle size, "V"-block can be positioned quickly, and measurement efficiency is high.
2, two compressed springs in the utility model are arranged relative to the axisymmetrical of locating piece, and compressed spring stress is more
Uniformly.
3, the gland in the utility model 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, the diameter and the outer diameter phase of compressed spring of groove in the utility model
Adaptation, compressed spring can be limited preferably.
