Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention can facilitate, measure accurately and rapidly and select clutch coupling (detent) collar thickness of automatic transmission, operating process robotization, ensures the assembly quality of automatic transmission, enhances productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is sounding rod structural representation in the present invention;
Fig. 3 is workpiece for measurement annular groove schematic diagram in the present invention;
Number in the figure: 1 sounding rod; 1a measures sheet; 1b shifting fork bar; 1c chute; 2 returning springs; 2a returning spring base; 3a measures support; Support is measured under 3b; 4 workpiece upper surfaces; 5 rotation cylinder; 6 upper cylinders; 7 displacement transducers; 8 annular grooves; 9 rotating shafts; 9a horizontal rotating disc; 9b pivot arm; 9c shifting block; 10 workpieces for measurement.
Embodiment
See Fig. 1 and Fig. 2, the version of the present embodiment mesopore annular groove measuring mechanism is:
Can the sounding rod 1 of fixed-axis rotation in vertically arranging, be that level is fixedly installed tongue-shaped measurement sheet 1a in the bottom of sounding rod 1, be that level is fixedly installed shifting fork bar 1b at the top of sounding rod, shifting fork bar 1b has been disposed radially chute 1c; Sounding rod 1 is set with returning spring 2, and the upper end of returning spring 2 is butted on shifting fork bar 1b, and lower end is butted on lower measurement support 3b, and sounding rod 1 and lower measurement support 3b are for being slidably matched.
In vertically arranging a rotating shaft 9, horizontal rotating disc 9a is connected firmly in the bottom of rotating shaft 9, horizontal rotating disc 9a is disposed radially pivot arm 9b, in the end of pivot arm 9b, shifting block 9c is set, shifting block 9c is slidably fitted in the chute 1c of shifting fork bar 1b, and the shifting block 9c rotated centered by rotating shaft 9 drives measurement sheet 1a to rotate centered by sounding rod 1 by shift fork 1b and sounding rod 1.
For realizing measuring, the upper cylinder 6 that rotating shaft can be driven to decline being set on the top of rotating shaft 9, the rotation cylinder 5 that rotating shaft 9 can be driven to rotate is set in the side of rotating shaft 9; On the top of sounding rod 1, displacement transducer 7 is set.
In order to ensure the accuracy measured, three sounding rods 1 being set and being uniformly distributed on the inner periphery of workpiece for measurement 10; Rotating shaft 9 is positioned at the top of sounding rod 1, is on the center of three sounding rod 1 place circumference.
In concrete enforcement, lower measurement support 3b is set directly at the upper surface of workpiece for measurement 10, and upper measurement support 3a is supported on lower measurement support 3b, and rotating shaft 9 and upper measurement support 3a are slidably matched, and displacement transducer 7 is fixed on to be measured on support 3a.
As shown in Figure 2, in assembling process, first adjust sounding rod 1 relative to the setting angle of shifting fork bar 1b and height, the measurement sheet in sounding rod 1 lower end relative to the angle of shifting fork bar 1b and height and position suitable time, tighten the mounting screw on shifting fork bar 1b, shifting fork bar 1b is fixed on sounding rod 1; Arrange returning spring base 2a, and have gap between the interstitial hole of returning spring base 2a and measurement axle 1, returning spring base 2a is fixedly mounted on lower measurement support 3b.Returning spring 2 will have certain precompressed, to provide suitable power upwards when assembling.
Workpiece for measurement 10 needs the distance A value of the upper surface of measuring workpieces upper surface 4 to annular groove 8.Sounding rod 1 is measured sheet 1a and need to possess rotation and Telescopic, when ensureing to retract, measuring system can drop to from above in the cavity of workpiece for measurement 10; After measuring system drops to fixing position, upper cylinder 6 stretches out, and drives sounding rod 1 to drop to appropriate location, makes sounding rod 1 to be measured sheet and be in the annular groove 8 of workpiece for measurement 10; Rotation cylinder 5 is stretched out, and drives sounding rod 1 to rotate, and makes sounding rod 1 to be measured sheet 1a and screws out in annular groove 8; Casing top half 6 bounces back, and sounding rod 1 moves upward under the effect of returning spring 2, contacts until sounding rod 1 is measured sheet with the annular groove upper surface of workpiece for measurement 10; The measuring head of displacement transducer 7 contacts with sounding rod 1 upper surface always, and now, system reads the numerical value of displacement transducer, by computing, draws the A value needing to measure; After measurement completes, upper cylinder 6 stretches out, and by sounding rod 1 being measured the annular groove upper surface of sheet top from workpiece for measurement 10, is in annular groove; Rotation cylinder 5 bounces back, and pulls sounding rod 1 to rotate, and makes sounding rod 1 to be measured sheet and inwardly rotates to initial position; Upper cylinder 6 bounces back, and measuring system bounces back, and departs from workpiece for measurement 9 internal cavities, completes whole measuring period.
