Fig. 1 is structural representation of the present invention;
Fig. 2 is sounding rod structural representation among the present invention;
Fig. 3 is workpiece for measurement annular groove synoptic diagram among the present invention;
Number in the figure: 1 sounding rod; 1a measures sheet; The 1b shifting fork bar; The 1c chute; 2 returning springs; 2a returning spring base; The upper measurement of 3a support; Measure support under the 3b; 4 workpiece upper surfaces; 5 rotation cylinder; 6 upper cylinders; 7 displacement transducers; 8 annular grooves; 9 rotating shafts; The 9a horizontal rotating disc; The 9b pivot arm; The 9c shifting block; 10 workpieces for measurement.
Embodiment
Referring to Fig. 1 and Fig. 2, the present embodiment mesopore with the version of annular groove measuring mechanism is:
But the sounding rod 1 that is vertical setting fixed-axis rotation is level and is fixedly installed tongue-shaped measurement sheet 1a in the bottom of sounding rod 1, be level at the top of sounding rod and be fixedly installed shifting fork bar 1b, has been disposed radially chute 1c at shifting fork bar 1b; At sounding rod 1 suit returning spring 2, the upper end of returning spring 2 is butted on shifting fork bar 1b, and the lower end is butted on lower measurement support 3b, and sounding rod 1 and lower measurement support 3b are for being slidingly matched.
Be a rotating shaft 9 vertically is set, connect firmly horizontal rotating disc 9a in the bottom of rotating shaft 9, be disposed radially pivot arm 9b at horizontal rotating disc 9a, in the end of pivot arm 9b shifting block 9c is set, shifting block 9c is slidingly fitted among the chute 1c of shifting fork bar 1b, and the shifting block 9c that rotates centered by rotating shaft 9 drives measurement sheet 1a by shift fork 1b and sounding rod 1 and rotates centered by sounding rod 1.
For realizing measuring, on the top of rotating shaft 9 upper cylinder 6 that can drive rotating shaft decline is set, can drive the rotation cylinder 5 of rotating shaft 9 rotations in a side setting of rotating shaft 9; On the top of sounding rod 1 displacement transducer 7 is set.
For the accuracy that guarantees to measure, three sounding rods 1 are set on the inner periphery of workpiece for measurement 10, evenly distribute; Rotating shaft 9 is positioned at the top of sounding rod 1, is on the center of three sounding rod 1 place circumference.
In the implementation, lower measurement support 3b is set directly at the upper surface of workpiece for measurement 10, and upper measurement support 3a is supported on the lower measurement support 3b, and rotating shaft 9 is slidingly matched with upper measurement support 3a, and displacement transducer 7 is fixed in to be measured on the support 3a.
As shown in Figure 2, in the assembling process, at first adjust sounding rod 1 with respect to the setting angle of shifting fork bar 1b and height, when the measurement sheet of sounding rod 1 lower end is suitable with respect to the angle of shifting fork bar 1b and height and position, tighten the mounting screw on the shifting fork bar 1b, shifting fork bar 1b is fixed in sounding rod 1; Returning spring base 2a is set, and has the gap between the interstitial hole of returning spring base 2a and the measurement axle 1, returning spring base 2a is fixedly mounted on the lower measurement support 3b.Returning spring 2 will have certain precompressed when assembling, so that the suitable power that makes progress to be provided.
Workpiece for measurement 10 needs the distance A value of measuring workpieces upper surface 4 to the upper surface of annular groove 8.Measure sheet 1a on the sounding rod 1 and need to possess rotation and Telescopic, in the situation that guarantees to retract, measuring system can be in the cavity that drops to workpiece for measurement 10; After measuring system dropped to fixing position, upper cylinder 6 stretched out, and drove sounding rod 1 and dropped to the appropriate location, was in the annular groove 8 of workpiece for measurement 10 so that measure sheet on the sounding rod 1; Rotation cylinder 5 is stretched out, and drives sounding rod 1 and rotates, and makes to measure sheet 1a on the sounding rod 1 and screw out to annular groove 8; Casing top half 6 retractions, sounding rod 1 moves upward under the effect of returning spring 2, contacts with the annular groove upper surface of workpiece for measurement 10 until measure sheet on the sounding rod 1; The measuring head of displacement transducer 7 contacts with sounding rod 1 upper surface always, and at this moment, system reads the numerical value of displacement transducer, by computing, draws the A value that needs measurement; After measurement was finished, upper cylinder 6 stretched out, and with measuring the annular groove upper surface of sheet top from workpiece for measurement 10 on the sounding rod 1, was in the annular groove; Rotation cylinder 5 retraction, pulling sounding rod 1 rotates, and makes to measure sheet on the sounding rod 1 and inwardly rotate to initial position; Upper cylinder 6 retractions, the measuring system retraction breaks away from workpiece for measurement 9 internal cavities, finishes whole measuring period.
