Seat 2 is assemblied on screw mandrel, and the regulation driving dovetail mount 2 of screw flange 23 is moved along screw mandrel.
Dovetail mount 2, which is provided with slide calliper rule seat, slide calliper rule seat, is fixed with digital vernier caliper 14, and regulation screw mandrel drives dovetail mount
While 2 movement, slide measure 14 is driven to move.Digital vernier caliper 14 is capable of the precision of " zero setting " and displacement use immediately
Up to 0.01mm, the true horizontal sample point data of display is coordinated using the display of torsion spring table with longitudinal direction and can be achieved to convexity workpiece
Measurement.
The dovetail mount 2 is provided with reference seat 7, end face push rod 15, and workpiece for measurement 8 is provided with the top of reference seat 7, measuring instrumentss
9 gauge head is located at the top of workpiece for measurement 8, and the reference seat is 7 double knife edges reference seats.
As depicted in figs. 1 and 2, when measuring 8 linearity of workpiece, workpiece 8 is placed between double knife edges reference seat 7, double knife edges
The length of spacing=50%~60% × workpiece for measurement 8.The summit of end face push rod 15 is in same horizontal line with the center of workpiece for measurement 8.
Along the light pressure of the surface direction of workpiece 8 pressure, regulation screw flange 23 is shaken, makes dovetail mount 2 drive workpiece for measurement 8 to reach
Add 0.3mm~0.8mm position after chamfering of being divided out below gauge head.The side surface locking bolt of column 12 is loosened, makes torsion spring table 9（0.5μ
M precision）Indicator shown to " 0 " position, slightly locking side bolt 13, after the completion of vertically move measuring instrumentss 9, make instrument
Display peaks, then drives regulation screw flange 23, makes workpiece for measurement 8 toward transverse shifting, instrument, which is shown, can increase or subtract
Few, through debugging repeatedly, until the transverse shifting of workpiece for measurement 8 is with when vertically moving, instrument shows maximum in the model less than 0.2 μm
Interior repetition is enclosed, now, shown instrument is linearity situation.
As depicted in figs. 1 and 2, during 8 shape measure of workpiece, to ensure that measurement shape starting point is correct, first torsion spring table

Near " 0 " position.Screw flange 23 can be shaken after putting former debugging needle roller into, the measuring point of workpiece 8 is reached the other end（Length is specified by drawing
Degree point）, now it should be observed that two-end-point gauge outfit show should be basically identical, two ends show value can be restored, now tightly should once be owned
Clamping screw and screw.It is finally putting into measured workpiece 8（Pin bus belt shape）, needle roller is put into rear thumb minute-pressure needle roller, shakes and adjust
Section screw flange 23 makes slide measure 14 show from 0 → A, to after " A ", by the reset of slide measure 14, makees ground zero, continues to shake
Dynamic regulation screw flange 23 is to next measuring point B, and the difference of the different value shown by instrument is the action H values in A-B chord lengths, the value
As convexity amount.
Exemplified by structure as shown in Figure 6, workpiece 8 reflected when 1mm points are moved to from end face from end face starting point to A point away from
From for 1mm, A points numeral slide measure 14 should reset again, record torsion spring gauge outfit show value, be rotated further regulation screw flange
23, make workpiece 8 toward moving left, the difference of show value when torsion spring gauge outfit show value is with newly " 0 " position during slide measure 14 to 2.45mmB points
Action value as in A-B chord lengths, it is also convexity amount to obtain being worth.Screw flange 23 is shaken it can be found that gauge head enters 9.1mm
Torsion spring list index is gentle during region, and almost very little changes, if occurring illustrating 9.lmm if pointer diminishes in 9.lmm regions
Region may have a depression, and general 9.lmm regions only allow straight or dimpling, repeatable 1~3 time of measurement process it is consistent preferably,
If error should be resetted when larger.Certainly debugging step ibid, is simply turned round in measurement length range during measurement straight edge line workpiece 8
Spring list index shows that almost ＜ is O.5（1）μm preferably, should be consistent with standard component test value.
Second component is equipped with up and down moving pairs on the column 12, and prismatic pair includes coattail board 27, dovetail slide block seat
