Description

A kind of measurer of degree of detection space of planes point distance
Technical field:
The invention belongs to machining fields of measurement, be specifically related to a kind of measurer of degree of detection space of planes point distance, for measuring space intersection that part degree face formed to distance size between its entity point.
Background technology:
Part manufacture need be undertaken processing and detecting by design drawing dimensioning.But the distance form between the design drawing space intersection that sometimes size marking become part degree face to be formed to its entity point, after causing part to process, this kind of size cannot directly be measured.Current solution one is that part spatial point is first processed into entity point, and after measurement entity point distance also records, then machined away by entity point, working (machining) efficiency is low; Two is that the special angle slide calliper rule of manufacture or special profile model detect, but affects part single-piece or small lot batch production economy; Three is carry out matching detection by three coordinate measuring machine, but the method is not suitable for the cost reality that little capital business equipment drops into.
Summary of the invention:
The object of the invention is to for above-mentioned the deficiencies in the prior art, provide a kind of measurer of degree of detection space of planes point distance, this measurer can be convenient for measuring the length distance between space intersection that part 0 ° ~ 140 ° degree faces are formed to material object parts point.
For achieving the above object, the present invention adopts following technical scheme to be achieved:
A measurer for degree of detection space of planes point distance, the ruler of existing universal protractor offers scale, and on this ruler, is provided with vernier and vernier to " 0 " block.
The present invention further improves and is, the precision of ruler high scale is 1mm.
The present invention further improves and is, the precision of vernier high scale is 0.02mm.
The present invention further improves and is, vernier is arranged on certain position of ruler to " 0 " block, and when this position is for making vernier carry out zero correction, its 0 scale mark overlaps with 0 scale mark of ruler.
Relative to prior art, the present invention has following advantage:
The function of chamfering slide calliper rule and universal protractor is carried out comprehensively by measurer provided by the invention, and based on universal protractor structure, and the ruler of measurer is equipped with vernier in appropriate location marking size scale.Regulate the annex such as ruler, angle square, range deflection fan of measurer during use, make the tip of range deflection fan aim at " 0 " scale mark of ruler.Then the measurement limit of ruler and range deflection fan is leaned against on the face twice of tested part, with the space intersection position finding part degree face to be formed respectively.Measured by ruler afterwards and with the use of the vernier be arranged on ruler, can read the length distance between space intersection that part degree face formed to material object parts point, measuring accuracy is 0.02mm.
In sum, the present invention is that the space intersection that part degree face is formed provides a kind of novel measurer to the direct measurement of distance size between material object parts point, and measurer provided by the invention is simple to operate, measuring accuracy is high, highly versatile, various parts single-piece or a small amount of production cost significantly can be reduced.
Accompanying drawing illustrates:
Fig. 1 is that 50 ° ~ 140 ° degree space of planes points use schematic diagram to entity point distance measurer;
Fig. 2 is that 0 ° ~ 50 ° degree space of planes points use schematic diagram to entity point distance measurer.
In figure: 1-ruler, 2-range deflection fan, 3-chi cover, 4-range deflection fan holding screw, 5-vernier, 6-vernier to " 0 " block, 7-holding screw, 8-part, 9-angle square.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As depicted in figs. 1 and 2, the measurer of a kind of degree of detection space of planes point of the present invention distance, the ruler 1 of existing universal protractor offers scale, and on this ruler 1, be provided with vernier 5 and vernier to " 0 " block 6, and vernier is arranged on certain position of ruler 1 to " 0 " block 6, when this position is for making vernier 5 carry out zero correction, its 0 scale mark overlaps with 0 scale mark of ruler 1.Wherein the precision of ruler 1 high scale is 1mm, and the precision of vernier 5 high scale is 0.02mm.
In order to further understand the present invention, now its using method is explained as follows.
Using method 1, as shown in Figure 1:
Step one: on the ruler 1 of measurer in appropriate location with every lattice 1mm marking size scale;
Step 2: be equipped with the vernier 5 that reading accuracy can reach 0.02mm on the ruler 1 that marking completes, and by the vernier be placed on ruler 1, by vernier 5, correct null position is adjusted to " 0 " block 6;
Step 3: by the ruler 1 to " 0 " block 6 inserts in chi cover 3 with vernier 5 and vernier.Regulate the annex such as ruler 1, range deflection fan 2 of measuring tool, with holding screw 7, ruler 1 is locked after making the tip of range deflection fan 2 aim at " 0 " scale mark of ruler 1;
Step 4: the measurement limit of ruler 1 and range deflection fan 2 is closely abutted on the face twice of tested part 8 respectively.By ruler 1 and range deflection fan 2 measure limit formed intersection point matching find out part degree face formed space intersection position after, with range deflection fan holding screw 4, range deflection fan 2 is locked;
Step 5: the distance size X coordinating vernier 5 to read on ruler 1 between space intersection that part 8 degree of faces are formed to part 8 entity point.Measuring accuracy is 0.02mm.
Using method 2, as shown in Figure 2:
Step one: on the ruler 1 of measurer in appropriate location with every lattice 1mm marking size scale;
Step 2: be equipped with the vernier 5 that reading accuracy can reach 0.02mm on the ruler 1 that marking completes, and by the vernier be placed on ruler 1, by vernier 5, correct null position is adjusted to " 0 " block 6;
Step 3: the ruler 1 of " 0 " block 6, angle square 9 are inserted in chi cover 3 by with vernier 5 and vernier.Regulate the annex such as ruler 1, range deflection fan 2, angle square 9 of measuring tool, the tip of range deflection fan 2 is made to aim at " 0 " scale mark of ruler 1, and making angle square 9 right-angle side be affixed on ruler 1, another right-angle side aims at " 0 " scale mark of ruler 1, ruler 1, angle square 9 is locked afterwards with holding screw 7;
