Abstract
An adjustable block gauge for measuring flatness is composed of an upper wedge block, a lower wedge and an insertion strip and is characterized in that the upper wedge block and the lower wedge are connected by the insertion strip through grooves in inclined planes of the upper wedge block and the lower wedge, and the upper wedge block and the lower wedge move along the inclined planes to change thickness, so that measurement on flatness or linearity of a plane subjected to machining is carried out. The adjustable block gauge is simple in structure, simple to match a flat ruler and three gauge blocks of equal thickness in use, high in measurement precision, fast in measurement speed, economical and durable, wide in application range and the like.
Description
Technical field
The utility model is about joiner's bench or the measuring measurer of associated mechanical, the measurer of especially a kind of measurement plane degree or linearity.
Background technology
Three point method is used in the joiner's bench measurement of planeness usually, promptly selects on tested plane at a distance of 3 of farthest a, b and c as reference point, and the gauge block of three uniform thickness is placed on these 3, and the upper surface of these gauge blocks is exactly the reference field of making comparisons with tested plane.The distance of measuring the plane that respective point in the tested plane and a, b, c constituted can record the flatness of lining face.Still not having at present special-purpose measurer and measure, is examining flat ruler to be placed on the uniform thickness gauge blocks such as a, b, c during measurement, by the distance on gauge block and clearance gauge measurement leveling ruler and tested plane, thus the flatness of measuring.The error of indication is big, and measuring accuracy is low, troublesome poeration.
The utility model content
The utility model has overcome deficiency of the prior art, and the adjustable slip gauge that a kind of error of indication is little, measuring accuracy is high is provided.
In order to solve the problem of above-mentioned existence, the utility model is taked following technical scheme:
1. this utility model is characterized in that being connected by a filler rod by the groove of upper and lower two voussoirs by its inclined-plane, and two voussoirs move along the inclined-plane, make its variation in thickness, thereby flatness or straight line degree measurement are carried out in the plane of machining.
2. two voussoirs described in " 1 " are that metal is made and an inclined-plane all respectively arranged, and a groove is respectively arranged in the middle of the inclined-plane, and groove connects by a filler rod that is made of metal thus, and playing the guiding role to move two voussoirs along the inclined-plane.
3. one side all has the scale mark that measures usefulness to upper and lower two voussoirs described in " 1 " on the inclined-plane, is respectively vernier scale and main scale.
4. when this utility model is measured, be used by 3-5 so adjustable slip gauge and an examining flat ruler and three uniform thickness gauge blocks.
Description of drawings
Fig. 1 is the structural representation of adjustable slip gauge;
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Among Fig. 1, the structural representation of adjustable slip gauge is by the last voussoir 1 with groove and dip plane and have the lower wedge block 4 of groove and dip plane, and the groove structure by upper and lower voussoir is connected by a filler rod 5 and forms; Main scale scale 3 is arranged on the lower wedge block, and last voussoir has vernier scale scale 2; The inclined-plane of last voussoir can move along the inclined-plane on the lower wedge block, makes the variation in thickness of adjustable slip gauge, and the vernier scale scale 2 by main scale scale 3 on the lower wedge block and last voussoir reads measurement data.
The last voussoir 1 of described adjustable slip gauge, lower wedge block 4 materials are the material of tool steel or suitable performance, and the scale marking width of main scale scale 3 and vernier scale scale 2 should be at 0.08-0.18mm, and the scale marking stand out should be not more than 0.02.The surfaceness of the measurement face on last voussoir 1, the lower wedge block 4 (non-inclined-plane) should be and is not more than R
a=0.2 μ m; Its flatness should be 0.003mm, measures in the face edge 0.2mm scope and allows the limit of collapsing.The inclined-plane of last voussoir 1, lower wedge block 4 should be through attrition process.
The depth of parallelism that the last voussoir 1 of described adjustable slip gauge and lower wedge block 4 are measured face should be not more than 0.01mm; The zero error of adjustable slip gauge is that adjustable slip gauge is when identical with uniform thickness gauge block thickness, " zero " mark on the vernier scale and " tail " mark and main scale should overlap, its registration should not surpass: " zero " mark registration is no more than ± 0.005mm, and " tail " mark registration is no more than ± 0.010mm.
The filler rod of described adjustable gauge block and the assembling of last voussoir notch should be transition fit, cooperate the clearance fit that should be loose slightly with the lower wedge block notch.
Claims (4)
1. the adjustable slip gauge of a measurement plane degree is characterized in that being connected by a filler rod by the groove of upper and lower two voussoirs by its inclined-plane, and two voussoirs move along the inclined-plane, make its variation in thickness, thereby flatness or straight line degree measurement are carried out in the plane of machining.
2. adjustable slip gauge according to claim 1, it is characterized in that described two voussoirs are that metal is made and an inclined-plane all respectively arranged, and a groove is respectively arranged in the middle of the inclined-plane, groove connects by a filler rod that is made of metal thus, and playing the guiding role to move two voussoirs along the inclined-plane.
3. adjustable slip gauge according to claim 1 is characterized in that, one side all has the scale mark that measures usefulness to upper and lower two voussoirs on the inclined-plane, is respectively vernier scale and main scale.
4. adjustable slip gauge according to claim 1 is characterized in that, is used by the such adjustable slip gauge of 3-5 and an examining flat ruler and three uniform thickness gauge blocks during measurement.
