Fig. 2 is the structural representation of correction unit in embodiments of the invention.
As shown in Figure 2, in the present embodiment, correction unit 60, for correcting the position of bat side support unit 32, makes V-type frame 321a play a supporting role, and spheroid 201 does not depart from ball seat (ball seat is two mobile side ball seats 313 and fixation side ball seat 22) simultaneously.
Correction unit 60 comprises: the first inductance amesdial 61 and two the second inductance amesdials 62.
First inductance amesdial 61 is located on spheroid 201, and spheroid 201 has placed on ball seat, in the present embodiment, bat 200 is placed on fixed support portion 20 and the second spheroid side support unit 31b, first inductance amesdial 61 is placed on above the first spheroid side support unit 31a, and the top contact of gauge head and spheroid 201.
Two the second inductance amesdials 62 and two bat collateral support component 321 one_to_one corresponding, the second inductance amesdial 62 is placed on the top of V-type frame 321a, and gauge head contacts with club 202.
The bearing calibration that correction unit 60 corrects V-type frame 321a is as follows:
Two spheroids 201 are placed on fixed support portion 20 and the second spheroid side support unit 31b by step 1 respectively.
Two slide blocks of the bat side support unit 32 between fixed support portion 20 and the second spheroid side support unit 31b are slided into the position of the Bezier point of bat 200 by step 2 respectively.
Step 3, regulates the second slide block respectively, and make the axis direction of V-type frame 321a and the axis being parallel of bat 200, namely club 202 just falls in V-shaped groove completely.
Three inductance amesdials are fixed by step 4, and by the gauge head of the first inductance amesdial 61 and ball top contact, indicating value is set to zero.Two other second inductance amesdial 62 is placed on above V-type frame 321a respectively, and gauge head contacts with club 202.
Step 5, regulates the 3rd slide block respectively along z to upward direction, drive V-type frame to move at vertical direction, search out the critical point that the second inductance amesdial 62 indicating value changes, this interval scale V-shaped frame 321a contacts completely with club 202.
Step 6, after searching out critical point, by the equal zero setting of these two the second inductance amesdial 62 indicating values.
Step 7, then continue upwards to finely tune 2 the 3rd slide blocks, keep the indicating value of two the second inductance amesdials 62 consistent at any time, until the indicating value of the first inductance amesdial 61 is undergone mutation, represent spheroid 201 and depart from ball seat.
Step 8, finely tunes two the 3rd slide blocks, finds the first inductance amesdial 61 indicating value and will to undergo mutation nonevent critical point, record two inductance amesdial 62 indicating value a.
Step 9, regulate two the 3rd slide blocks downwards, until indicating value is a/2, now, the supplemental support effect namely representing two V-type framves reaches.Achieve bat 200 when measuring, gravity is caused to the compensation of distortion.
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, at metering field, the application of interference length-measuring is generally Jin You mono-road interfeerometry ranging in a dimension.And due to the singularity of bat structure, need to have two-way interferometry signal in a dimension, and make the optical axis coincidence of two light paths.Measuring process is:
1., on the mobile side ball seat 313 bat 200 two spheroids 201 being placed on respectively the first spheroid mobile unit 31a and on the fixation side ball seat 22 of fixed support portion 20, the interferometry signal of initialization first measurement section 40a is zero.
2. moving the first spheroid mobile unit 31a makes on the mobile side ball seat of spheroid 201 to the second spheroid mobile unit 31b of the low order end of bat 200, and recording the displacement that the first measurement section 40a records is a, and the interferometer of the measurement section 40b of initialization second is simultaneously zero.
3. moving the second spheroid mobile unit 31b makes the left end spheroid 201 of bat move on fixation side ball seat 22, and recording the displacement that the second measurement section 40b records is b.
4. the centre of sphere distance of a bat is L=a+b.
Based on this measurement rules, the design and dress school of pick-up unit just need meet abbe ' s principle, the dead in line that the axis of guarantee interferometry axis and bat and sliding table move, thus reduce cosine error to greatest extent.Because one-shot measurement only need complete by several specific location point on guide rail, avoid the slip of worktable Long travel on guide rail, the impact of guide rail linearity error can be reduced to the full extent.This reduces the requirement to guide rail linearity to a certain extent.Therefore, under meeting bat axis and measuring the prerequisite that overlaps of axle, guide rail linearity meets 2 μm/m, and the cosine error introduced by guide rail linearity error can be ignored in the process of uncertainty evaluation.
Fig. 4 is the workflow diagram of the detection method of bat centre of sphere device for detecting distance in embodiments of the invention.
As shown in Figure 4, use the concrete steps of the bat centre of sphere distance detecting method of bat centre of sphere device for detecting distance 100 as follows:
Step S1, closes the air supporting switch of attached for aspiration stationary work-table 23, makes it be fixed on the centre position of guide rail 11, then enter step S2.
