Fig. 3 is the displacement transducer floor plan of detector of the present utility model.
Embodiment: gerotor type outer rotor detector of the present utility model comprises that gerotor type outer rotor detection of packets instrument of the present utility model comprises support 8, elastic centering anchor clamps 4, centering guiding mechanism 5, electrical control measuring mechanism 2, operating mechanism 1, elastic centering anchor clamps 4 are made of resilient sleeve 9 and column 10, centering guiding mechanism 5 is for having 90 ° of V-type alignment mechanisms that slide and shrink, be fixed on described bracket end face, operating mechanism 1 is installed in support 8 bottoms, connect with column 10 lower ends, handle the clamping of 4 pairs of parts of elastic centering anchor clamps; Electrical control measuring mechanism 2 comprises controller 12, display 13 and displacement transducer 7,11, sensor 7,11 and controller 12 are by being electrically connected, the sensor side head is arranged round internal rotor along circumference, have 8, the floor plan of sensor as shown in Figure 4, sensor 7 is measured along the diametric(al) of circumscribed circle, has 4 sides 14 to contact with the teeth top of internal rotor; Sensor 11 is measured along the diametric(al) of incircle, has 4 sides 15 to contact with the tooth root of internal rotor.During measurement, elastic centering clamp system 4 passes the internal rotor center pit and clamps, and is against the teeth of internal rotor 6, centering measuring position by the V-type alignment mechanism 5 that is fixed on bracket end face.
Be example explanation testing process with EQ1141 lubricating oil pump outer rotor now: as shown in Figure 1, two groups of diameter parameters that need to detect are φ 32
+ 0.779 + 0.830, φ 52
+ 0.591 + 0.642, the concrete steps of detection are:
A, at first measured piece is eliminated the measuring error that causes thus by elastic centering clamp system Reasonable Orientation;
B, make the desirable measuring position of part very accurately coincide with the measuring position of instrument by having 90 ° of V-type alignment mechanisms that slide to shrink, thereby eliminate: because two groups of diameter parameters of part are all at same measurement plane because the improper caused error of centering, there is 45 ° phase differential inscribed circle and circumscribed measuring position, and every group of diameter parameters has 90 ° phase differential, therefore when measuring, phase place centering requirement accurately to be arranged, i.e. the gauge head of sensor true value that records inscribed circle and circumcircle diameter parameters surely when measuring;
C, the measuring mechanism that has a displacement transducer are measured, and two groups of diameter parameters shared 10 each displacement transducers are seen shown in Figure 3;
D, parameter is detected, divides into groups, the measured value that shows on the display: A
