Abstract
The utility model relates to the vernier gauge caliper used for measuring length, used as a vernier caliper and a gauge which can adjust measuring range random or a plug gauge. The vernier gauge caliper can simply and accurately measure the central distance of a hole or a slot. The working principle is used by the measuring tool to the gauge field, the gauge can be used as a vernier caliper, and the disadvantages that the special gauge just can test one dimension but can not carry out adjustment are overcome. The utility model has the advantages of one vernier caliper with multipurpose, flexible use, low cost, high durability, high efficiency, etc. The figure is the functional diagram of the vernier gauge caliper.
Description
The present invention is a novel dimensional measuring instrument.Need workplace that machined object is carried out linear measure longimetry at each, measuring method commonly used at present generally has two kinds, and a kind of is to wait and measure with graduated general measurer such as vernier caliper, milscale; A kind of is to check with the limit gauge of no scale.Two kinds of measuring methods cut both ways.The present invention improves on the basis of vernier caliper, has designed both to can be used as vernier caliper and use, and can be used as multi-usage measurer---the vernier gauge slide calliper rule that the calliper that can arbitrarily adjust measurement range or feeler gauge use again.
Vernier caliper can directly be measured the physical size of testee, but efficiency of measurement is low.Be subjected to the influence of survey crew individual factor bigger, when producing in enormous quantities, be restricted.Though gauge is easy to use, quick, accurate, a secondary gauge can only be checked the surface of a size and a kind of tolerance usually.After size or tolerance change, just need redesign, make new gauge, this is economical inadequately concerning single-piece or small serial production.
The objective of the invention is to advantages, the vernier principle of work is applied to the gauge field, overcome special-purpose gauge and can only check a size, the shortcoming that can not adjust vernier caliper and gauge.
Vernier gauge slide calliper rule are made up of a main scale and the secondary chis of two verniers, on main scale and the vernier pair chi with measuring jaw in, have at least three measuring jaws can to move or adjust mutually.Three measuring jaws like this can constitute two different sizes.As required, a size can be adjusted into the go side size that allows testee to pass through, and another size can be adjusted into the not-go-end size that stops testee to pass through, and the measuring jaw position of adjusting is fixed with clamping screw, has just constituted a secondary gauge.In the whole measurement range of main scale, can be adjusted to the gauge of any one dimensional tolerence.When not needing to do the gauge use, this measurer still can be made vernier caliper and use.
Accompanying drawing is the fundamental diagram of vernier gauge slide calliper rule.
Fig. 1 is in the view of zero position for measuring jaw.The secondary chi of the vernier on the pulling right side, measurer just can use by common vernier caliper.
Fig. 2 is the vernier gauge fundamental diagram.When the zero line on the secondary chi of left side vernier is aimed at the scale value " 2 " on the main scale left side, above the slide calliper rule face of two measuring jaws and following two measuring jaws the slide calliper rule face in correspondence with each other, be in same reference position.If need a certain size of check, routine φ 30hg(
-0 -0.084) time, with the scale value " 3 " that the zero line on the secondary chi of right side vernier is aimed at the main scale right side, the slide calliper rule face of at this moment following two measuring jaws has formed go side size " 30 "; Vernier secondary chi in the left side is done slight adjustment to the right, move 0.084, the slide calliper rule face of then top two measuring jaws has formed not-go-end size 30
-0.084, the secondary chi of the vernier on both sides is fastening with clamping screw, just constituted the calliper of checking this dimensional tolerence of φ 30hg.Measuring jaw position available internal diameter milscale is adjusted.
Fig. 3 is the fundamental diagram of vernier feeler gauge.When the zero line on the secondary chi of left side vernier is aimed at the scale value " 1 " on the main scale left side, above the clearance gauge face of two measuring jaws and following two measuring jaws the clearance gauge face in correspondence with each other, be in same reference position.If need certain size of check, routine φ 40Hg(
+ 0.062 + 0) time, the scale value " 3 " that the zero line on the secondary chi in the right side is aimed at the main scale right side, because of the clearance gauge face of following two measuring jaws has the width of 10mm after altogether, they have promptly constituted go side size " 40 "; The secondary chi in the left side is done slight adjustment left, move 0.062, the clearance gauge face of then top two measuring jaws has constituted not-go-end size 40
+ 0.062
If 1/2nd numerical value with scale value on the scale face of the main scale left side mark, then this measurer can be used for the centre distance of measured hole or groove.Common calliper measuring center distance needs through measurements and calculations several times; Not only time-consuming but also easily make mistakes.Then very easy with this gage measuring centre distance, as long as the indicated scale value addition of zero line on 1/2nd scale values that zero line on the secondary chi of the vernier on the left side is indicated and the secondary chi of the right vernier is tested centre distance.
As Fig. 4
M＝L＋N
Centre distance=1/2(M+N)
＝1／2（L＋2N）
＝1／2L＋N
According to above-mentioned principle of work, in order further to improve efficiency of measurement, can adopt vernier gauge slide calliper rule as shown in Figure 5, also can design the vernier gauge or the vernier feeler gauge of independent use.
The present invention has the following advantages:
1, the many usefulness of a chi are easy to use, can be according to producing needs flexible transformation use-pattern, thus improve efficiency of measurement and production efficiency.
2, can reduce the expense of design, manufacturing, the special-purpose gauge of keeping, reduce production costs.
3, the method for available adjustment slider position solves behind the measurement surface wear of this measurer.Therefore when making gauge and use, the go side size stay that mill measures comparable special-purpose gauge stay the mill amount little, can allow more to pass through near the qualified part of dimension limit.The wearing and tearing that special-purpose gauge is measured face will be scrapped above behind the prescribed limit, and this measurer is just reusable after adjusting a little.
The explanation of accompanying drawing drawing:
Accompanying drawing 1 is in the view of zero-bit for vernier gauge slide calliper rule measuring jaw.
Accompanying drawing 2 is the vernier gauge fundamental diagram, and 1 is main scale, and 2,3 is the secondary chi of vernier, and 4 is clamping screw.
