The groove principle: being carved with each little lattice on the blade is the scale mark of 0.5mm, and when measuring jaw closed up, the zero graduation line of blade alignd with chi frame reading baseline; The pitch of micrometer screw mandrel is 0.5mm, and promptly screw mandrel circles, and moves axially 0.5mm simultaneously, and the left end tapered circumference on the microdrum is provided with the scale mark of 50 five equilibriums, and the reading of each little lattice is 0.5/50mm=0.01mm.
During measurement, at first to allow chi frame and fine motion frame have adjustable clearance, make simultaneously that the zero graduation line aligns with fixed muffle reading baseline on the microdrum; According to the size of workpiece size, determine the Position Approximate of chi frame on blade earlier, then promptly than about the big 1～3mm of physical size, tighten fixedly fine motion frame position of lock-screw, the constant device of rotation dynamometry drives differential screw mandrel and microdrum and rotates, the promotion chi is frameed shift moving, and workpiece is measured.
During reading, at first read chi frame reading baseline and aim at blade high scale numerical value, numerical value should be the integral multiple of 0.5mm; See the line that fixed muffle reading baseline aligns with microdrum high scale line then; With two numerical value additions, be exactly the measured value of this workpiece at last.
The utlity model has following advantage:
1, how to integrate vernier caliper, outside micrometer, micrometer inside caliper, micrometric depth gauge with the vernier micrometer callipers, simple in structure, of many uses;
2, use the measurement range of vernier micrometer callipers big, the precision height can the survey scope be 0～150mm, 0～200mm, 0～300mm etc. more, and its precision is 0.01mm, has remedied the deficiency of existing vernier caliper and milscale;
3, how to have multi-functional with vernier micrometer, easy to use, measure fast, multiple functions such as energy measurement internal diameter, external diameter, the degree of depth and step, its measuring accuracy all mostly is 0.01mm;
4, have differential measurement non-regulating function, only need during use microdrum zero graduation line alignment fixed muffle reading baseline is got final product.
