The locating detent 302 and the maximum displacement for limiting the locating detent 302 radially-inwardly (the left-hand direction in Fig. 2 and Fig. 3).
Locating detent 302 is run through by the second locating part 322, while gap is provided therebetween, to allow locating detent 302
Displacement or movement.But the second locating part 322 provides radially inner extreme position to locating detent 302, in other words, works as positioning
When pawl 302 is moved radially inward to the second 322 competing position of locating part, then locating detent 302 reaches radially inner
Maximum displacement and extreme position, it is impossible to be further continued for deformation or displacement.
Second locating part 322 can be arranged on vertical block in several ways, such as can be fixedly connected or a bodily form
Into.But preferably, the second locating part 322 is detachably connected for example, by screw thread and vertical block, therefore can be to locating detent 302
Radially inner extreme position controllably adjusted, to be adapted to different operating modes.Second locating part and locating detent 302
Restriction effect can be realized by the ledge structure in through hole or latch structure.
Utilize the above-mentioned locating part including the first locating part 321 and/or the second locating part 322, it can be ensured that at locating detent
Within rational deformation, displacement range.First locating part 321 and the second locating part 322 can also have other suitable installations
Mode, and the installation settings being not limited on vertical block.
Under preferable case, locating detent have it is multiple, the plurality of locating detent be evenly arranged around the central shaft 100 and with it is described
Multiple claws are staggered, and the assembled shaft 10 is kept in the state of the measurement position in the multiple claw, described fixed
Position pawl can contact at the assembled shaft 10.That is, when claw keeps assembled shaft 10 to be in measurement position, locating detent energy
The precalculated position of the assembled shaft 10 of part based on enough contacting at.Specifically, circumferential grooves are provided with the assembled shaft 10,
In the measurement position, the upper surface of the circumferential grooves of the assembled shaft 10 is supported by the multiple claw, the multiple positioning

In fixing bracket 304, adjusting gasket 333 is set.Therefore, by adjusting the thickness of adjusting pad, realize measuring basis block 331 and survey
The position for measuring unit is adjusted.
Measurement process
Behind upper surface using the circumferential grooves of multiple claws clamping assembled shaft of hoisting mechanism, lifting assembled shaft 10 is to most
High position (i.e. measurement position).
After the completion of deduction action, that is, meet the technological requirement that workpiece makes up fit-up gap.It is next after workpiece stabilization
Step measures action using measuring mechanism.
Under the action of tension spring, locating detent is open configuration in initial position.Then, start driver 313, such as make
The piston rod for obtaining cylinder stretches out, and will contact and pushes up connecting rod 308.With the increase of cylinder stroke, connecting rod 308 drives roller to turn left
Movement, at the same locating detent under the action of compression spring 311 all the time by pressure to the left.When roller 312 moves to left, then hook portion 309 is being pressed
To left movement, locating detent starts to receive and support in locating detent along one angle of clockwise oscillation in elastomer opening position the power of spring
Touch in the upper surface of the circumferential grooves of assembled shaft 10.
Meanwhile the state of tension is between lower rocker piece below roller and upper rocker piece all the time, as described above, floating downward
Parallelogram mechanism is formed between motion block, upper rocker piece and vertical block and fixing bracket.Therefore, when roller is along lower floating
When the upper surface of block is moved to the left, due to having ramp structure on lower rocker piece, between upper rocker piece and lower rocker piece
Under the action of tension spring, lower rocker piece moves up.Simultaneously as lower rocker piece is fixedly connected with vertical block, so result in perpendicular
The action or displacement that straight block is produced to correspondingly upper action or displacement, the vertical block can be examined by sensor 303 installed above
Survey and obtain, and obtain corresponding numerical value, which can obtain required measured value by computing.
Pass through detection of the measuring basis block 311 to the end face of housing in addition, combining, the circumferential direction of above-mentioned assembled shaft can be obtained
The distance between upper surface and housing end face of groove.
