According to the technical scheme of the center line gauge, upper and lower ends of a cuboid ruler rack are provided with sliding tracks, the sliding tracks are equipped with tooth bars, tail ends of the tooth bars are fixed with measuring pins, a gear is equipped between the two tooth bars, the gear is fixedly connected with a bearing through a shaft and then is engaged with the tooth bars, and a center ruler is fixed at a center of the ruler rack. The center line gauge can rapidly determine the center line or the center position of the object and has advantages of simple use, high work reliability and accurate positioning. The center line gauge not only can position a box body, a beam end and a track, but also can position center lines or center positions of other objects having regular geometric bodies.

Description

Center line calliper
Technical field
The utility model relates to mechanical engineering, measurer field, is specifically related to a kind of calliper of locating center line or center.
Background technology
The method of now general searching object center line or center is the mode by measuring, such as at mechanical engineering field, the mechanical property of measuring material plays an important role to whole mechanical development, the measurement of mechanical property has a lot of different experimental techniques, wherein one is exactly tension test, tension test sample used need to be delimited gauge length in the time that normal temperature stretches, in the time of drawing by high temperature, and the thermopair that also need use at the center of sample welding thermometric except delimiting gauge length.For example, being that circular sample is while carrying out stretching experiment to a cross section, the method of traditional measurement tensile sample center is: first go out the length of Lc in Fig. 1 with ruler measurement, then calculate the size of Lc/2, the position that finally measures Lc/2 taking arbitrary end as benchmark is center.But this kind of method is more loaded down with trivial details, this method can not be carried out centralized positioning and gauge length demarcation to multiple samples simultaneously simultaneously.Fast and accurately determine object center every field all tool be of great significance.As Chinese patent open file CN201941432U discloses a kind of adjustable drawing compass for centerline of beam ends device, it is mainly used in locating beam-ends center line; Chinese patent open file CN102199906A discloses a kind of track centerline ruler device, only limits to locate the midline position of railroad track.But a kind of center line or center of installing energy positioning object is also badly in need of in other some fields.The object of center line calliper of the present invention is center line or the center of quick positioning object and gauge length accurately delimited.
Summary of the invention
In order to determine fast and accurately center line or the center of object in every field, the utility model provides a kind of center line calliper, this center line calliper can not only solve the problem that some fields lack location center line or center device, and can determine fast object center line or center and delimit gauge length.
The technical scheme of center line calliper of the present utility model is: at the upper and lower two ends of rectangular parallelepiped chi frame, slideway is set, tooth bar is housed on slideway, tooth bar end and measuring jaw are fixed, between two tooth bars, gear is housed, gear is fixedly connected with bearing by axle afterwards and tooth bar meshes together, and paper centering scale is fixed on Chi Jia center.
Two described measuring jaw front ends adopt slope.
Described paper centering scale front end is fixed with scale, has the scale taking millimeter as unit on scale, and scale is movable, can be connected and fixed by bolt and paper centering scale, and the shape of scale is square waveform.
The beneficial effects of the utility model are: determine fast and accurately center line or the center of object, and use is simple, functional reliability is high, accurate positioning.This center line calliper is except locating casing, beam-ends, track, and the object that other are had to regular geometric body can be located its center line or center equally.

Embodiment
In Fig. 2, slideway 2 is fixed on chi frame 1, tooth bar 3 is arranged on slideway 2, measuring jaw 8 is fixed with tooth bar 3 ends, gear 4 is fixedly connected with bearing 7 by axle 6 afterwards and tooth bar 3 meshes together, paper centering scale 12 is fixed on chi frame 1 center, in the time that needs are measured gauge length, scale 10 can be fixed on paper centering scale 1 and measure.Described two measuring jaws, 8 front ends adopt slope.Described paper centering scale (12) front end is fixed with scale (10), scale has the scale taking millimeter as unit on (10), scale (10) is movable, can be connected and fixed by bolt and paper centering scale (12), the shape of scale (10) is square waveform.
Specific embodiment 1: in Fig. 5, sample is carried out in location, center, measuring jaw 8 is in the process contacting with sample, tooth bar 3 starts mobile along slideway 2, by the transmission of gear 4, tooth bar 13 also moves along slideway 9, when measuring jaw 8 is stuck in sample two ends by the time, stops, the position that is arranged on the center reference A indication of the paper centering scale 12 on chi frame 1 is the center of sample, has completed the location of sample center with scoring tool along paper centering scale picture straight line.If sample delimited to gauge length, can install gauge length instrument 10, moving forward and backward paper centering scale 12 makes gauge length instrument be placed on the position that sample is suitable, suppose taking the distance between benchmark B and benchmark C as gauge length, so only need draw straight line and completed respectively with scoring tool the demarcation of gauge length along the benchmark B of gauge length instrument and benchmark C.
Specific embodiment 3: in Fig. 6, multiple samples being carried out in center and gauge length location simultaneously, make equally measuring jaw 8 and sample clamping, the position that is arranged on the center reference A indication of the paper centering scale 12 on chi frame 1 is the center of sample, move forward and backward equally paper centering scale 12 and make gauge length instrument be placed on the position that sample is suitable, the distance between benchmark B and benchmark C is gauge length.
Specific embodiment 4: in Fig. 7, the utility model can also carry out centralized positioning to right cylinder bottom surface, first the distance of adjusting two secondary measuring jaws 8 makes itself and right cylinder contacts side surfaces, to ensure that paper centering scale 12 is on right cylinder bottom surface simultaneously, now draw straight line along paper centering scale with scoring tool, this straight line is exactly bottom surface diameter of a circle; Then rotate certain angle, same method is drawn straight line along paper centering scale with scoring tool, and the intersection point of these two straight lines is exactly the center of right cylinder bottom surface.
Specific embodiment 5: the utility model can also carry out center line location to rectangular parallelepiped surface as shown in Figure 8, first the distance of adjusting two secondary measuring jaws 8 makes itself and rectangular parallelepiped Surface Contact, to ensure paper centering scale 12 just and rectangular parallelepiped Surface Contact simultaneously, then draw straight line along paper centering scale 12 use line tools, this straight line is exactly the center line on rectangular parallelepiped surface.
