Abstract

The utility model relates to a combined gage caliper with a plurality of functions, which comprises two caliper rods articulated with each other, the caliper feet fixed on the lower end of the caliper rod and the measuring heads symmetrically installed on the lower end of the caliper rod, and the utility model still comprises a figure display device. When in using and measuring, the measuring result only need to be read out from the meter, which makes reading figure more rapid, intuitionistic with high measuring precision. The utility model is mainly used in the mechanical processing and mechanical manufacturing fields with a plurality of functions like internal diameter measuring, external diameter measuring and circle drawing.

Description

A kind of digital display Combined calliper gauge
Technical field
The utility model relates to a kind of multi-functional calliper, particularly a kind of Combined calliper gauge with digital display meter.
Background technology
In machining, mechanical manufacturing field, often need draw circle on the various workpieces surface, this just need plan; When manufacturing machine part in batch, often need use caliper gauge, snap gauge in addition.When we need draw circle, survey internal diameter and survey external diameter, just need possess above-mentioned instrument, patented claim (application number is 200320129211.2) in 2003 just relates to a kind of technical scheme of Combined calliper gauge in person, this technical scheme possesses the internal diameter of survey, surveys external diameter, draws multiple functions such as round, comprise two hinged gauge bars, the gauge bar two ends rule pin of planing, the gauge bar lower end is arranged with the gauge head that can be fixed on the gauge bar; In addition, described Combined calliper gauge also can be equipped with the reading chi that the main scale that then has scale and graduated scale are formed.Such Combined calliper gauge need carry out reading by the scale of careful identification reading chi, especially the scale mark comparatively dense on the rule, graduated scale number hour, reading just seems concerning the user, and some is painstaking, precision can not be guaranteed.
Summary of the invention
The purpose of this utility model is exactly that a kind of Combined calliper gauge that reading is directly perceived, precision is high that has digital display meter will be provided.
Goal of the invention of the present utility model is to realize like this, by my patented claim in 2003 is improved, fundamentally say so and on the basis of planing, improve, a kind of Combined calliper gauge is provided, this Combined calliper gauge comprises two hinged gauge bars, be fixed on the rule pin of gauge bar lower end, be symmetricly set on the gauge head of gauge bar bottom, and described Combined calliper gauge also comprises the device for digit-displaying that is arranged between two gauge bars.
Described device for digit-displaying is made up of scale and digital display meter, scale is fixed on the gauge bar, be that hinged central point with two gauge bars is the arc chi in the center of circle, the sensor sleeve of digital display meter is contained on the arc scale and is fixed on another gauge bar, forms with scale to be slidingly matched.
Described rule pin, when the gauge head symmetry is fixed on the gauge bar, the hinged central point that rule end, underfooting, the measuring point of gauge head are in two gauge bars is on the same circular arc in the center of circle.
Adopt the Combined calliper gauge of above structure, guaranteed when the angular displacement sensor of digital display meter when scale slides, the angle that is become between two rule pin, the two corresponding gauge heads and angular displacement sensor on the arc scale of process radian, and the angle surveyed of angular displacement sensor be linear relationship.Measurement result is accurate when using and measure, and can read measurement result from table intuitively, makes reading more intuitively convenient, the measuring accuracy height.
In addition, this digital display Combined calliper gauge also comprises gauge bar aperture adjusting stationary installation.This gauge bar aperture is housed regulates the digital display Combined calliper gauge of stationary installation, can avoid the relative slip between two gauge bars, avoid unnecessary error.
Below in conjunction with specific embodiment and Figure of description the utility model is described in detail.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is a geometrical principle synoptic diagram of the present utility model.
Embodiment
On fundamentally saying so the basis of planing, improves digital display Combined calliper gauge shown in Figure 1, this Combined calliper gauge has hinged gauge bar 11,12, rule pin 21,22 is fixed on gauge bar 11,12 lower ends, be arranged with gauge head 31,32 in the gauge bar bottom, scale 4 and digital display meter 5 are formed device for digit-displaying, scale 4 is arc chis that are the center of circle with the hinged central point O point of two gauge bars 11,12, be fixed on the gauge bar 11, digital display meter 5 is sleeved on the arc scale 4 and is fixed on the gauge bar 12, and digital display meter 5 drives its angular displacement sensor and can slide along scale 4.
When rule pin 21,22 and gauge head 31,32 symmetries are fixed on the gauge bar 11,12, bottom A, the B of rule pin 21,22 and the measuring point A of gauge head 31,32 1, B 1And A 2, B 2The hinged central point O that is in two gauge bars 11,12 is on the same circular arc in the center of circle.
In addition, this digital display Combined calliper gauge also comprises gauge bar aperture adjusting stationary installation 6.
The sensor of digital display meter 5 is commercially available angular displacement sensor shaped article.The use of this digital display Combined calliper gauge is as follows: regulate the angle of release that stationary installation 6 is determined between two gauge bars by regulating the gauge bar aperture.Start index when angle measurement is spent is the hinged central point O of gauge bar and the line and the intersection point A ' of scale 4 scale center lines of the measuring point A of rule pin 21, the measuring head of digital display meter angular displacement sensor be positioned at the intersection points B of the hinged central point O of gauge bar and line and the scale 4 scale center lines of the measuring point B that advises pin 22 '.
The signal that the angular displacement sensor measuring head records, handle according to corresponding formulas through data processor, can obtain the different pieces of information of corresponding survey internal diameter, external diameter, stroke radius of circle and angle respectively, can pass through the liquid crystal display displays measurement result, corresponding button is arranged on the digital display meter, can select as requested.
Geometrical principle between the above-mentioned data is: establish ∠ AOB=∠ A ' OB '=a, OA=OB=L, the radius of a circle of drawing of planing so AB = L 2 ( 1 - cos a ) ; Because ∠ is AOA 2=∠ BOB 2=b is constant, ∠ AOA 1=/BOB 1=c is constant, so the result when surveying external diameter A 2 B 2 = L 2 [ 1 - cos ( a - 2 b ) ] ; Result when surveying internal diameter A 1 B 1 = L 2 [ 1 - cos ( a + 2 c ) ] .
