Technical field
The utility model relates to a kind of milscale, and particularly a kind of milscale for cone workpiece measuring outside diameter belongs to the measurer technical field.
Background technology
At present, generally having the Outer Taper workpiece that degree of precision requires, all is to use the cone ring gauge to measure.A kind of ring gauge can only be measured a kind of workpiece, and the ring gauge manufacturing expense is high, and the cycle is long, and measurement is wasted time and energy, and measuring accuracy is but not too high.Another kind method is to adopt the platform measuring technology to measure, and this measuring method is confined to little, the lightweight part of measurement volumes, and can not measure at lathe, so usable range is narrower.Therefore, need to provide a kind of easy to use, measuring accuracy is high, can adapt to the measurer of various Outer Taper workpiece external diameter measurings.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, thus the cone outside micrometer that providing a kind of measures conveniently, cost of manufacture is low, measuring accuracy is high, measurement range is wide.
The purpose of this utility model is achieved through the following technical solutions: the cone outside micrometer, comprise clock gauge, the gauge head installed on chi frame and the chi frame, clock gauge is installed in an end of chi frame, upper gauge head is installed in the sounding rod end of clock gauge, lower gauge head is installed on the gage button of chi frame lower end, it is characterized in that, the gauge head that install at described chi frame two ends is the identical scarce round post measuring stick of radius, two faces of cylinder that lack round post measuring stick are relative, axis is parallel to each other, lack the axis of round post measuring stick vertical with the sounding rod axis and with its at grade.
Chi frame and clock gauge junction rear side are the plane and slide block are installed, be processed with two T-shaped grooves parallel with sounding rod on the slide block, slide block is by T-shaped groove and chi frame slidable adjustment location, be screwed between slide block and the chi frame and be connected, the slide block lateral surface is parallel with the axis that lacks round post measuring stick, and slide block lateral surface to sounding rod center size equates with the radius that lacks round post measuring stick.
The outer side bus place that is installed in the scarce round post measuring stick of clock gauge one end wears into facet, and facet is towards the slide block lateral surface, and facet is parallel with the slide block lateral surface, and the distance of facet and slide block lateral surface is 0.01-0.02mm.
Described scarce round post measuring stick is that end face is greater than the right cylinder of semicircle.
When the utility model is measured cone, be not subjected to the restriction in workpiece size, weight, putting position and place, can directly measure at lathe, greatly facilitate the operator, and can increase substantially production efficiency.The utility model is simple in structure, and is easy to use, and measurement range is wide, and measuring accuracy is high, and is swift to operate, safe and reliable.

Embodiment
The cone outside micrometer comprises identical scarce round post measuring stick 4 and the slide block 3 of diameter that install at chi frame 1, clock gauge 2 and chi frame two ends.Lack round post measuring stick and be end face greater than the right cylinder of semicircle, why select to lack round post measuring stick, but second first weight reduction can increase measurement range.
Clock gauge is installed in an end of chi frame, the sounding rod that upper scarce round post measuring stick is installed in clock gauge is terminal, lacking down round post measuring stick is installed on the gage button of chi frame lower end, two faces of cylinder that lack round post measuring stick are relative, axis is parallel to each other, lack the axis of round post measuring stick vertical with the sounding rod axis and with its at grade.
Chi frame and clock gauge junction rear side are the plane, and slide block is installed on this plane, are processed with two T-shaped grooves parallel with the sounding rod axis on the slide block, and slide block is by T-shaped groove and chi frame slidable adjustment location, are screwed between slide block and the chi frame to be connected.The slide block lateral surface is parallel with the axis that lacks round post measuring stick, and the slide block lateral surface equates with the radius r of scarce round post measuring stick to sounding rod center size b.The outer side bus place that is installed in the scarce round post measuring stick of clock gauge one end wears into a facet, and facet is towards the slide block lateral surface, and facet is parallel with the slide block lateral surface, facet and slide block lateral surface be 0.01-0.02mm apart from a.During measurement and cone end face retention gap, can guarantee to lack round post measuring stick and move up and down freely.
Fig. 3 to Fig. 6 is cone gradient and large and small end diameter measuring method synoptic diagram, and lacking round post measuring stick radius among the figure is r.Proofread and correct two with proof-reading block before measuring and lack between round post measuring sticks apart from M0, clock gauge is set to null value.Prop up dull and stereotyped 6 with top 7 and be adjacent to cone 5 end faces, adjust slide position and fixing, to lack round post measuring stick and cone Down Highway and the large end of cone (small end place flat board 6) end face tangent with lower with left hand, lack round post measuring stick with putting on the hand thumb again, all the other four fingers are close to large end (small end place flat board 6) end face with chi frame slide block, then thumb is unclamped gently, make scarce round post measuring stick and cone Up Highway UHW tangent, get measured value e.Large and small end data is measured complete, and measured value e is added proof-reading block size M
0Be M1 (M2) size with scarce round post measuring stick diameter d, record two ends distance between the surface L, substitution with inside diameter caliper again
Formula 1:tg α=(M1 – M2)/2L;
Ctg[(90 ° of formula 2:D1=M1 – 2r+α)/2];
Ctg[(90 ° of formula 3:D2=M2 – 2r-α)/2];
Can try to achieve cone bevel angle α and cone outside diameter D1, cone end diameter D2.
In order to reduce gauger's calculated amount, can large and small end diameter D1, the D2 of tapering will be commonly used, proof-reading block size M0, measuring head diameter d and measured value e are tabulating up and down, choose corresponding measured value according to diameter is large and small during measurement, directly read measured value and get final product.
