Description
Technical field
The invention belongs to mechanical detection field of measuring technique, and in particular to a kind of suitable for detecting workpiece end face circle bounce
Measuring device.
Background technique
Circle bounce is when referring to that element to be measured is revolved one-turn around datum axis, and the indicator fixed by position is in given directions
The difference of the maximum and least count that measure.Circle bounce point is radial, end face and three kinds oblique.The title of bounce is associated with measurement
, part is turned round around datum axis when measurement, and the gauge head of measurement dial gauge contacts element to be measured, indicator gage finger when revolution
Jerk value is exactly the numerical value of circle bounce.Dial gauge gauge head refers on cylindrical surface as radial run-out, refers in end face to be that end face circle is jumped
It is dynamic, it is perpendicularly oriented on circular cone element line be oblique circle bounce.
Workpiece after the assembly is completed, round pulsation measurement need to be carried out to workpiece, checks whether to meet matching requirements under normal conditions,
If design requirement is not achieved in orchard run-out tolerance, illustrates that workpiece centre is not coaxial with datum axis, will appear when rotation is used
Bias, therefore the dismounting of desired workpiece will be unsatisfactory for and ressembled.The method of measurement is as follows, and dial gauge is mounted on dial framework
On, dial framework is slowly moved, contacts the measuring head of dial gauge with tested end face, and keeps vertical, pointer is returned to zero, and is had certain
Decrement.Slowly and equably turning of work piece one week, and the fluctuation of percentage list index is observed, take full-scale reading Max and minimum
The difference for reading Min, as the Circular Run-out Tolerance error delta i at the diameter.
When workpiece alignment measurement for having outer box structure, stablize when in order to guarantee measurement, measurement side at this stage
Formula is that will measure a piece metal extension bar of installation on dial framework to be used to fix dial gauge, then extend into tray interior and measures,
Two class problems can be brought in this way: first is that the assembly space of box body structure is limited, if it is coaxial to need to be packed into several in space
Workpiece, one layer of workpiece of every loading in this way require to measure primary circle bounce, and metal extension bar is easily artificially touched in measurement process
It arrives, deviation occurs in the circle pulsation measurement datum mark for causing workpiece.Second is that when tray interior needs to assemble magneto, box body
Interior space will appear magnetic field, and magnetic force has adsorption capacity to metal, and metal extension bar can vibrate in measurement process, into
And influence measurement numerical value.
