Fig. 2 is the structural representation of correction unit in embodiments of the invention.
As shown in Fig. 2 in the present embodiment, correction unit 60 is used to be corrected the position of bat side support unit 32,
V-type frame 321a is set to play a supporting role, (ball seat is two mobile side ball seats 313 and fixed while spheroid 201 is without departing from ball seat
Side ball seat 22).
Correction unit 60 is included：First inductance amesdial 61 and two the second inductance amesdials 62.
First inductance amesdial 61 is located on spheroid 201, and spheroid 201 has been placed on ball seat, in this implementation
In example, bat 200 is placed on the spheroid side support unit 31b of fixed support portion 20 and second, and the first inductance amesdial 61 is placed
Above the first spheroid side support unit 31a, and the top contact of gauge head and spheroid 201.
Two the second inductance amesdials 62 are corresponded with the collateral support component 321 of two bats, the second inductance amesdial 62
V-type frame 321a top is placed on, gauge head is in contact with club 202.
The correction V-type frame of correction unit 60 321a bearing calibration is as follows：
Step 1, two spheroids 201 are individually positioned on the spheroid side support unit 31b of fixed support portion 20 and second.
Step 2, by two of the bat side support unit 32 between the spheroid side support unit 31b of fixed support portion 20 and second
Individual sliding block slides into the position of the Bezier point of bat 200 respectively.
Step 3, the second sliding block is adjusted respectively so that V-type frame 321a axis direction and the diameter parallel of bat 200, i.e.,
Club 202 is just fallen completely within V-shaped groove.
Step 4, three inductance amesdials are fixed, the gauge head of the first inductance amesdial 61 contacted with top dome, indicating value is put
It is zero.Two other second inductance amesdial 62 is individually positioned in above V-type frame 321a, and gauge head is contacted with club 202.
Step 5, adjust the 3rd sliding block respectively to upward direction along z, drive V-type frame to be moved in vertical direction, search out the
The critical point that the indicating value of two inductance amesdial 62 changes, this interval scale V-shaped frame 321a is completely attached to club 202.
Step 6, after critical point is searched out, by the two equal zero setting of the indicating value of the second inductance amesdial 62.
Step 7, it is further continued for finely tuning 2 the 3rd sliding blocks upwards, the indicating value one of two the second inductance amesdials 62 is kept at any time
Cause, until the indicating value of the first inductance amesdial 61 is undergone mutation, represent spheroid 201 and depart from ball seat.
Step 8, two the 3rd sliding blocks are finely tuned, finding the indicating value of the first inductance amesdial 61 will undergo mutation nonevent face
Boundary's point, records two indicating value a of inductance amesdial 62.
Step 9, two the 3rd sliding blocks are adjusted downwards, until indicating value is a/2, now, that is, represent the auxiliary branch of two V-type framves
Support effect has reached.When realizing the measurement of bat 200, the compensation of deformation is caused to gravity.
Fig. 3 is the process schematic of bat centre of sphere device for detecting distance in embodiments of the invention.
As shown in figure 3, only having interfeerometry ranging all the way on metering field, usually one dimension of application of interference length-measuring.
And because the particularity of bat structure in a dimension, it is necessary to have two-way interferometry signal, and make the optical axis weight of two light paths
Close.Measurement process is：
1. 200 two spheroids 201 of a bat be individually placed on the first spheroid mobile unit 31a mobile side ball seat 313 and
On the affixed side ball seat 22 of fixed support portion 20, the first measurement portion 40a of initialization interferometry signal is zero.
2. the first spheroid mobile unit 31a of movement makes the spheroid mobile unit of spheroid 201 to the second of the low order end of bat 200
On 31b mobile side ball seat, the displacement that the first measurement portion 40a of record is measured is a, while initializing the dry of the second measurement portion 40b
Interferometer is zero.
3. the second spheroid mobile unit 31b of movement makes the left end spheroid 201 of bat be moved on affixed side ball seat 22, record
The displacement that second measurement portion 40b is measured is b.
4. the centre of sphere of a bat is away from for L=a+b.
Based on the measurement rules, with regard to abbe's principle need to be met in the design of detection means and dress school, it is ensured that interferometry
The axis that axis is moved with the axis and sliding table of bat is overlapped, so as to reduce cosine error to greatest extent.Because once
Measurement several specific location points need to only complete on guide rail, it is to avoid the slip of workbench long stroke on guide rail, can be maximum
Reduce the influence of guide rail linearity error in degree.This reduces the requirement to guide rail linearity to a certain extent.Therefore exist
On the premise of meeting bat axis and measurement overlapping of axles, guide rail linearity meets 2 μm/m, introduced by guide rail linearity error more than
String error can be neglected during uncertainty evaluation.
