Description

The vernier micrometer callipers of using more

Technical field

The utility model relates to vernier caliper, is specifically related to the vernier micrometer callipers of using more.

Background technology

At present, being used for the measurer commonly used that general precision such as mechanical component measures is vernier caliper, and it has easy to use, advantages such as measurement range is big, and is of many uses, but because its structural reason, its measuring accuracy is lower, so can only be used for the measurement that general precision requires low part.For the measurement of degree of precision, generally adopt the spiral micrometer measuring implement to measure, as outside micrometer, micrometric depth gauge, micrometer inside caliper etc.These micrometer measuring implements have improved measuring accuracy, but it measures range and diminished, and are a ruler with the 25mm range generally, and this ruler can only be measured the size in this range ability, as exceed this measurement range and will change ruler in another range ability.In addition, the purposes of this class micrometer measuring implement is also more single, and one can only measure a physical dimension to ruler, can only measure external diameter as outside micrometer, and micrometric depth gauge can only fathom, and micrometer inside caliper can only be measured internal diameter etc.Sometimes need use manyly ruler for measuring a part, as vernier caliper, many milscale, pit gauge, micrometer inside caliper etc., this use to the user, keeping etc. bring inconvenience.

Summary of the invention

The purpose of this utility model is: provides a kind of and uses the vernier micrometer callipers more, and simple in structure, to measure accurately, a chi is used more.

Technical solution of the present utility model is: these slide calliper rule comprise blade, chi frame and pit gauge, the chi frame is installed on the blade by spring copper sheet and can slides on blade, chi frame reading baseline is arranged on the chi frame, pit gauge is installed in the elongated slot of the blade back side and is linked together with the chi frame, measuring claw and external pelivimetry pawl in blade and chi frame are provided with, it is characterized in that: micrometering mechanism is installed on blade, micrometering mechanism comprises the micrometer screw mandrel, the fine motion frame, fixed muffle, microdrum, the fine motion frame is installed on the blade by spring copper sheet and is close to also and can slides on blade with blade, the fine motion frame is provided with fixed muffle, the micrometer screw mandrel is installed in the fixed muffle, one end of micrometer screw mandrel is connected on the hold-down nut on the chi frame, the affixed microdrum of the micrometer screw mandrel other end, microdrum is enclosed within outside the fixed muffle.

Of the present utility model many with in the vernier micrometer, micrometer screw mandrel tail end is installed the constant device of dynamometry.

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.
