It is situated between and is connected, can is the connection inside two elements.It for the ordinary skill in the art, can be as the case may be
Understand concrete meaning of the above-mentioned term in the utility model.
As shown in Figure 1, 2, 3, a kind of accurate measurement instruments used for education based on abbe's principle, including pedestal 1, pacify on pedestal 1
Equipped with the X direction guiding rails 2 apart from pedestal table top with height, the X that slides along is installed to sliding block 3 on X direction guiding rails 2, X is to sliding block
The first reading head 4 and the second reading head 5 for having height apart from pedestal table top are installed, 1 table top of pedestal is equipped with and supplies respectively on 3
First reading head 4 and the second reading head 5 carry out first grating scale 6, the second grating scale 7 of reading, and second grating scale 7, which is mounted on, hangs down
It can directly slide in the Y-direction guide rail 8 of vertical plane and along Y-direction guide rail 8 where the X direction guiding rails.
First reading head 4 and the second reading head 5 are installed to X to sliding block 3 by fixture 9.
X direction guiding rails 2 are parallel to 1 length direction of pedestal.
Reading head guide rail 10 is installed, the second reading head 5 is mounted on reading head guide rail 10 and can be along reading on fixture 9
Head guide rail slides.
Y-direction guide rail 8 is formed for two closed slides.
Y-direction guide rail 8 is made of wear-resistant material.
1 bottom of pedestal is equipped with to adjust the adjustment knob of 1 levelness of pedestal.
From figure 1 it appears that pedestal is divided into two regions in left and right along substantially symmetrical about its central axis.Left area installs the first grating
Ruler 6, and it is fixed；Right area sets Y-direction guide rail and installs second grating scale 7, makes it that can move in the Y direction.It is right
Answer two grating scales respectively there are two reading head, X is mounted on sliding block by fixture so that it can along grating scale move into
Row pin-point reading.In addition, reading head guide rail 10 has also been devised on fixture, the second reading head is mounted on reading head guide rail 10, can
So that it has small range adjustment in the Y direction.
In order to fully demonstrate the inherent feature of Abbe error and property, we devise following experiment, such as Fig. 4, Fig. 5, figure
6th, shown in Fig. 7, Fig. 8.
In experiment, we are using first grating scale 6 as standard volume, and second grating scale 7 as being measured, make by the first reading head
For reading point, the second reading head is as aiming point.
The explanation of classical abbe's principle, which refers to be measured, to be in standard volume on same straight line, therefore is met shown in Fig. 4
Abbe's principle, and Fig. 5 does not meet abbe's principle, wherein being measured with standard volume not on the same line, the two is led at intervals of A
Rail inclination angle is φ, then Abbe error amount α can be calculated according to formula (1).
When standard volume and it is measured on the same line, as shown in 6,7, and aiming point is on this straight line, and
It is first-order error by the aiming arm error of generation when deviateing S in the Y direction with reading point：
The guide rail of X-direction provides motion guide for reading head, and working face is guide surface.When standard volume is in measured
On same straight line, as shown in figure 8, and guide surface not when on this straight line, and measured point away from guide surface distance for G, G is referred to as
Leading arm then generates leading arm error, is first-order error：
Abbe's principle is the essence guideline of Precision Machinery Design, is had wide range of applications, and looks back the hair of abbe's principle
Exhibition course and the application in new instrument, with reference to, in feature and property, having carried out more systematic research in it.With reference to Ah
The latest development viewpoint of shellfish principle, we devise experimental program, fully demonstrate and demonstrate classical Abbe error, aim at arm mistake
Difference and guiding surface error are that the characteristics of student is to abbe's principle and fully understanding for property provide effective help.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
