It states switching mechanism side and is provided with erection support, measuring instrument ontology, the measuring instrument ontology are installed at the top of the erection support
On be provided with the detector of monodactyle.
Using a kind of above-mentioned numerically control grinder measurement structure for machining crankshafts, when installing bent axle, the switching mechanism
In 0, the measuring instrument ontology upward, makes the detector far from the workbench at this time, to prevent bent axle to institute
Stating the when of being installed on workbench collides the detector, and after the completion of crankshaft installed, the switching mechanism downwardly turns over 180 °, makes institute
Stating erection support drives the measuring instrument ontology to downwardly turn over, and so that the detector is overturn to crankshaft diameter and opens on the inside of shelves, measures
Before, it first passes through the workbench band dynamic crankshaft and moves, it is complete to make the detector touch to the wherein side of crankshaft thrust face
At the positioning of the measuring instrument ontology, the workbench drives crankshaft reversal movement, to make the detector touch to crank
The other side of thrust surface, to make described this physical efficiency of measuring instrument accurately measuring basis reset be opened in thrust shoe the center of shelves
Position, to eliminate because upper process centre bore chamfering angle size causes easily to collide or measure error when described this bulk measurement of measuring instrument
Cause and measure failure feedback in lathe false data, by measuring value opening grade center and carry out the right and left, calculates and value
It carries out comparing to reach actually dividing equally with tender, to improve the accuracy of measurement.
Preferably, the workbench is X to movable working platform.
Preferably, the fixed plate is mounted on by bolt on the grinder bed.
Preferably, the switching mechanism is overturning oil cylinder, and the flip angle of overturning oil cylinder is 0 ° -180 °.
Preferably, the erection support is L-type.
Preferably, the measuring instrument ontology is T18 measuring instruments.
Advantageous effect is：1, the utility model is kept away by the way that the measuring instrument ontology to be mounted on above the workbench
When exempting from crankshaft installed, the detector is collided, to greatly save the adjustment time of measuring instrument；
2, the measuring instrument ontology is driven to overturn by the switching mechanism, to make the detector when not measuring,
It can be downwardly turned over to bent axle far from the workbench when measuring；
3, accuracy of measurement is high, and not will produce measurement illusion.
