Embodiment
The utility model is described further below in conjunction with drawings and examples.
Simultaneously as simply section Example described below, in the case where not conflicting, embodiment in the application and
Feature in embodiment can be mutually combined.
A kind of digital display calliper, include the number for being provided with the chi body 1 of sensor and being electrically connected with sensor as illustrated in fig. 1 and 2
Aobvious panel 2, the chi body 1 include the main scale and vernier scale 12 for being separately installed with measuring jaw 11, and the measuring jaw is self contering structure, from
Adjective-centre structure includes the cylinder being connected with chi body and the cone for realizing positioning, and the cylinder is located above cone, institute
The central shaft of cone and cylinder is stated on same straight line.
The measuring jaw 11 is integrally formed, and the height ratio of the cone and cylinder is 1:1.5~1:2.5, preferably 1:
2。
The sensor is linear pattern capacitor grid transducer, and the moving grid pole plate of the linear pattern capacitor grid transducer is arranged on vernier
On chi 12, fixed grid pole plate is arranged on main scale.The slide calliper rule using capacitor grid transducer have small volume, simple in construction, resolution ratio and
The advantages of degree of accuracy is high, measuring speed is fast, small power consumption, low, less demanding to use environment cost, can effectively realize to object
Accurately measure.
The linear pattern capacitor grid transducer electrically connects with the processing module in digital display panel 2, will directly measure the data obtained
Transmit to processing module.
Display 21 and hole count enter key 26, the hole count enter key 26 and digital display face are provided with the digital display panel 2
The input module connection set in plate 2, the input module electrically connect with processing module, the processing module and display module electricity
Connection, the display module electrically connect with display 21, can show measurement or the data calculated.
Circumferential apertures process of measurement is provided with the processing module, measurement switching push button is provided with the digital display panel 2
23, the measurement switching push button 23 electrically connects with processing module, can realize the flexible switching of slide calliper rule function.
The measuring jaw of slide calliper rule two is placed directly in hole such as Fig. 5 during measurement, main scale also with regard to auto-paralleling in the end face of tested metering-orifice,
So as to ensure that the concentricity of cone and tested metering-orifice.Having shown in Fig. 6 just conversely occurs if A and B is not parallel
One taper head incomplete contact between is tested the situation of metering-orifice, so only two cones of slide calliper rule need to be completely attached into measured hole, you can
Ensure that A is parallel with B's, also just reach self-centering effect, can effectively ensure that the accuracy of measurement and positioning.
The method of measurement plane pitch-row is：It is zeroed after Data panel 2 is opened, presses measurement switching push button, slide calliper rule are adjusted
To straight hole process of measurement, two measuring jaws 11 are holes pitch-row by the position to hole, reading.Or slide calliper rule are adjusted to circumferential apertures
