Working principle:
The circular arc type tooth turbine disk 10 has to be different from along each position distance over bar of arc surface, but consistent due to tooth form
Property, as long as determining the distance over bar of center, the distance over bar of other positions also be can determine, therefore be surveyed by measurement by three coordinates
Amount can calculate the distance of the centre distance datum plane of the tooth of measurement and the distance over bar at tooth center from the present invention, which cleverly passes through, to be pushed away
The measuring head 59 of spring 58 and elastic connection (the first spring 594) quickly searches out the center of 10 tooth of the turbine disk, and measures in tooth
Height value of the heart apart from datum plane and the distance across ball.
By the position of the first slideway 42 and the second slideway 43 adjustment positioning bulb 41 and fixation, make it and turbine to be measured
Disk 10 matches, and the turbine disk 10 is placed in 21 in cavity, and quickly the handle 321 of folder 32 unclamps, and the benchmark of the turbine disk 10 is put down
Face is pressed on cavity 21, therefore the datum plane of the turbine disk 10 is the contact plane that can be considered cavity 21 Yu the turbine disk 10；It is sliding
The positioning bulb 41 that bar 44 connects is embedded into tooth, it is therefore an objective to so that the measurement contact stud 593 in measuring head 59 measures any tooth
Same position；Measuring block push rod 57 is rotated clockwise, measuring block 54 is pushed into be located at the turbine disk 10 far from the second vertical plate 52
Then tooth center left reversely rotates measuring block push rod 57, so that the contact bulb of measuring block push rod 57 and measuring block 54 are detached from,
Measuring head 59 is set to suffer from one's own actions 10 tooth center of the turbine disk, i.e. pushing away by the first spring 594 by the effect of push spring 58 and elastic connection
The center of arc for measuring contact stud 593 is pushed into the center of 10 disk tooth of the turbine disk by the synergistic effect of power and push spring 58, realizes measurement
The center for suffering from one's own actions disk tooth of head；The numerical value for reading the second digital display dial gauge 56 is the height of Turbo-Disk Tooth centre distance datum plane
Degree, the numerical value for reading the first digital display dial gauge 55 is the distance over bar at Turbo-Disk Tooth center.
