Suit moves measuring staff, moves alternate by the spring of coaxial package between measuring staff and quiet measuring staff, dynamic axis of the measuring staff relative to quiet measuring staff of composition
To elastic extension structure.The dynamic measuring staff and quiet measuring staff being vertically arranged window from pedestal stretch out, in two measuring staff overhanging ends towards on lateral surface
One coaxial bulb bolt is installed respectively, constitutes the M value measurement structures for leaning on real workpiece internal tooth by opposite thirty years of age of bulb bolt.It is described
Spacing ring is in tennis racket shape, and racket portion is directly sleeved on dead axle and on the left of dynamic measuring staff, shank runs through pedestal from inside to outside
One side wall, exposed thread segment are furnished with wing nut, this locking mechanism is positioned the dynamic measuring staff of setting by spacing ring.It is described
For dial gauge location and installation on pedestal, gauge head vertically abuts against dynamic measuring staff stage casing outer wall, and the pointer for thus forming dial gauge is servo-actuated
Measuring staff and dynamic M value measurement structures.
As the scheme that is further improved, the dynamic measuring staff stage casing side is equipped with a horizontal overhanging handle.
As the scheme that is further improved, the bulb diameter of the bulb bolt is equal to selection standard steel ball size.
As the scheme that is further improved, the spring is compression type springs.
As the scheme that is further improved, the bar portion lateral cross section of the dynamic measuring staff and quiet measuring staff is rectangle.
Compared with prior art, the present invention having the positive effect that：
1, desk-top contraposition measurement structure is simple, is easy to make, easy to use, and measurement efficiency is high；
2, it moves measuring staff position to be set up with standard workpiece in advance, the displacement of dynamic measuring staff is quantified by the pointer of dial gauge when reality measures
Instruction, therefore surveyed M values precision is high；
3, the present apparatus is made of purely mechanic parts, and to measuring environment without particular/special requirement, it is online that M values are made in particularly suitable production scene
It measures.

Specific implementation mode
Below according to attached drawing and in conjunction with the embodiments, the invention will be further described.
Fig. 1, internal gear shown in Fig. 2 and M value of internal spline measuring device, it is by pedestal 1, dead axle 2, spacing ring 3, dial gauge
4, measuring staff 5, bulb bolt 6, quiet measuring staff 7 and spring 8 is moved to collectively constitute.The pedestal 1 is rectangular box main component.Pedestal 1 or so
Wall lower part is equipped with the coaxial through-hole of placement dead axle 2, and left side wall top is equipped with the through-hole of inserting dial gauge 4, disposes the through-hole of dead axle 2
It is parallel with the inserting through-hole of dial gauge 4.1 roof of pedestal is equipped with the rectangular window of hollow out between two parties, which is dynamic measuring staff 5 and quiet
The reserved channel of measuring staff 7.The dead axle 2 is straight-bar axis, and when installation extends transversely through preset coaxial in 1 or so wall lower part of pedestal and leads to
Hole.To realize 2 location and installation of dead axle, nut 2.2 is configured at 2 both ends of dead axle, stage casing is equipped with radial evagination shoulder together.It is described quiet
Measuring staff 7 and bushing 2.1 are sleeved on successively on 2 right axis section of dead axle, and quiet measuring staff 7 is by the radial evagination shoulder axial limiting on dead axle 2.
It is set in 2 left axle section of dead axle and moves measuring staff 5, move alternate by the spring of coaxial package 8 between measuring staff 5 and quiet measuring staff 7, spring used
8 be a kind of compression type springs, this structure composition moves axial elasticity stretching structure of the measuring staff 5 relative to quiet measuring staff 7.It is sleeved on dead axle
The bar portion of dynamic measuring staff 5 and quiet measuring staff 7 on 2 is vertically arranged upward without exception, and free end is reserved rectangular window from 1 roof of pedestal and stretched
Go out.For the ease of measuring, the bar portion lateral cross section of dynamic measuring staff 5 and quiet measuring staff 7 in the present invention is rectangle, opposite in overhanging end
One coaxial bulb bolt 6 is installed respectively on side, the internal spline circular tooth thickness of the present embodiment workpiece for measurement 9 be dimensioned for
3.14mm routinely selects the standard length bar of identical or slightly larger diameter or steel ball to be used to measure, and bulb bolt 6 used in the present embodiment is such as
Shown in Fig. 4, the bulb of diameter 3.5mm is chosen by standard series.With two identical sizes and opposite thirty years of age of bulb bolt 6 when measurement
Make M values by 9 internal spline of real workpiece to measure.For the ease of setting the range position for moving measuring staff 5, the present invention is in 5 stage casing side of dynamic measuring staff
Face is equipped with a handle 5.1 as shown in Figure 3, and dynamic measuring staff 5 and handle 5.1 are as shown in Figure 8 after connecting.Spacing ring in the present invention
3 as shown in Figure 5, Figure 6, and the spacing ring 3 of this likeness in form tennis racket is attached to racket portion set on locating shaft, and position must be surveyed dynamic
5 left side of bar, the shank of spacing ring 3 run through 1 one side wall of pedestal, wing nut 3.1 are equipped on exposed thread segment from inside to outside,
Such spiral locking mechanism is positioned the dynamic measuring staff 5 of setting by locating ring 3.4 location and installation of the dial gauge is in pedestal 1
On, gauge head vertically abuts against 5 stage casing outer wall of dynamic measuring staff, and the pointer for thus forming dial gauge 4 is servo-actuated measuring staff 5 and dynamic measurement knot
Structure.M value ranges first are set with standard component before measuring, that is, sets up the position for moving measuring staff 5, then dial gauge 4 returns to zero.Remove standard
Part, change the outfit workpiece for measurement 9, moves up and down workpiece 9, and the circular tooth thickness margin of error drives dynamic measuring staff 5 to make corresponding axial direction through bulb bolt 6
Displacement, displacement change M values, specific displacement by dial gauge 4 pointer with respect to zero-bit instruction.Since measurement result is direct
Quantization instruction, it is high certainty of measurement, efficient.In addition, the present apparatus is made of purely mechanic parts, measuring environment is wanted without special
It asks, so being particularly suitable for production scene makees M value on-line measurements, can avoid that the overproof problem of batch occurs.
