Embodiment
Below in conjunction with specific embodiment the utility model is described:
Embodiment:
The via depth measurement mechanism that adopts in the present embodiment comprises linear displacement transducer 2, two rod cylinders 4, side-looking Fibre Optical Sensor 8.
The cylinder piston rod of two rod cylinders 4 runs through whole piston cylinder, and the piston rod two ends stretch out piston cylinder, and the moving of piston can drive piston rod two ends link simultaneously and move with displacement in the same way.One end of two rod cylinder 4 piston rods by displacement transducer connector 3 and linear displacement transducer 2 be fixedly linked, the other end of two rod cylinder 4 piston rods is fixedly linked by Fibre Optical Sensor connector 7 and side-looking Fibre Optical Sensor 8, and two rod cylinders 4 are coaxial installation with linear displacement transducer 2 and side-looking Fibre Optical Sensor 8, make the axial displacement of side-looking Fibre Optical Sensor 8 to be delivered to exactly on the linear displacement transducer 2.Side-looking Fibre Optical Sensor 8 is selected reflection-type side-looking Fibre Optical Sensor for use.
Two rod cylinders 4, linear displacement transducer 2 and side-looking Fibre Optical Sensor 8 are installed in the measurement mechanism shell 1, measurement mechanism shell 1 is the hollow cylinder structure, in the present embodiment because two rod cylinders 4 are different with the external diameter of linear displacement transducer 2, so the through hole of measurement mechanism shell 1 is a step through-hole, the large aperture of step through-hole is identical with two rod cylinder 4 external diameters, the small-bore of step through-hole is identical with linear displacement transducer 2 external diameters, two rod cylinders 4 are fixedlyed connected with measurement mechanism shell 1 one ends by set nut 5, and linear displacement transducer 2 adopts interference fit to fix with step through-hole.
For the accuracy that guarantees to measure, when side-looking Fibre Optical Sensor 8 moves axially, the moving direction that guarantees side-looking Fibre Optical Sensor 8 is parallel with the central axis of through hole to be measured, so the utility model also includes supporting seat 6, supporting seat 6 is hollow frustum cone structure, the end that two rod cylinders 4 are installed in supporting seat 6 osculum ends and the measurement mechanism shell 1 is fixedly linked, and the central axis of supporting seat 6 frustum cone structures and measurement mechanism shell 1 central axis conllinear.In order better to observe the position of side-looking Fibre Optical Sensor 8 and through hole to be measured, on supporting seat 6 frustum cone structure sidewalls, have viewport.In addition, at supporting seat 6 big opening ends flange is arranged, plane, flange place is perpendicular to the supporting base central axis.In order to guarantee side-looking Fibre Optical Sensor 8 operate as normal, supporting seat 6 adopts transmission material.
Two rod cylinders 4, linear displacement transducer 2 and side-looking Fibre Optical Sensor 8 link to each other with peripheral control unit respectively, during present embodiment work, supporting seat 6 end face flanges are close to surface of the work, make measurement mechanism central axis through-bore axis parallel and to be measured, and the viewport that passes through supporting seat 6 is observed, guarantee that side-looking Fibre Optical Sensor 8 is in the top of through hole to be measured, peripheral control unit starts linear displacement transducer 2 and side-looking Fibre Optical Sensor 8, drive two rod cylinder 4 setting in motions simultaneously, and drive side-looking Fibre Optical Sensor 8 and linear displacement transducer 2 motions.Because supporting seat 6 adopts transmission materials, by controller externally side-looking Fibre Optical Sensor 8 induction threshold values are set and make 8 pairs of supporting seats 6 of side-looking Fibre Optical Sensor insensitive.After two rod cylinders 4 driving side-looking Fibre Optical Sensors 8 are sensed through hole to be measured, the 2 record displacements of peripheral control unit control linear displacement transducer, stretch out through hole to be measured up to side-looking Fibre Optical Sensor 8, when no longer sensing through hole to be measured, linear displacement transducer 2 stops to write down displacement, thereby obtains the degree of depth of through hole to be measured.
When via depth measurement mechanism of the present utility model is integrated in the automation equipment, does not then need supporting base 6, but need automation equipment to guarantee that via depth measuring center parallel axes is in through-bore axis to be measured.
