Abstract
The utility model discloses a measuring tool for circle center determination. The measuring tool comprises a center cone frustum, a left connecting rod and a right connecting rod. One end of each of the left connecting rod and the right connecting rod is rotatably connected with the center cone frustum by means of surrounding a circle center of the center cone frustum; the other end of each of the left connecting rod and the right connecting rod is respectively and fixedly connected with a left cone frustum and right cone frustum which are the same with the center cone frustum in diameter; straight lines where the left connecting rod and the right connecting rod are located intersect at the circle center of the center cone frustum and penetrate the circle center of each of the left cone frustum and the right cone frustum; perpendicular bisectors of the left connecting rod and the right connecting rod are respectively and fixedly connected with a left measuring rod and a right measuring rod. The measuring tool for the circle center determination is simple in operation and visual, and measuring efficiency and accuracy can be improved.
Description
Technical field
The utility model relates to a kind of survey instrument of definite center of circle, in particular for determine the survey instrument as central portion centers of circle such as flange, disks in mechanical industry.
Background technology
Usually adopt the manual method searching centers of circle such as construction with ruler and compasses in the present known mechanical industry, but have problems such as troublesome poeration, efficient is low, degree of accuracy is not high.
Summary of the invention
At above-mentioned weak point of the prior art, the utility model provides a kind of survey instrument of definite center of circle, and is easy and simple to handle, directly perceived, improves and measures efficient and precision.
The technical solution of the utility model is a kind of survey instrument of definite center of circle, comprises left connecting rod, right connecting rod that center round platform and an end all are rotatably connected with it around the center of circle of center round platform; The other end of described left and right connecting rod is fixedly connected with the left and right round platform identical with described center round platform diameter respectively; The straight line at described left and right connecting rod place intersects at the center of circle of center round platform, and passes through the center of circle of left and right round platform respectively; Perpendicular bisector by described left and right connecting rod is fixedly connected with left and right sounding rod respectively.
In technique scheme, because left and right connecting rod can rotate around the center of circle of center round platform, make to form an angle between two connecting rods to guarantee that center round platform and left and right round platform are all tangent with tested central portion; Because linking to each other respectively, the round platform center of circle, center, the left round platform center of circle and the parts center of circle, the tested center of circle can form an isosceles triangle, so left connecting rod is equivalent to the base of this isoceles triangle shape, left side sounding rod is equivalent to the perpendicular bisector on base and crosses summit (the tested central portion center of circle), in like manner right sounding rod is also crossed the center of circle of tested central portion, because intersecting, two straight lines have only an intersection point, and two sounding rods are all crossed the tested central portion center of circle, so the intersection point of left and right sounding rod is the center of circle of tested center of circle parts.
Further, described center round platform comprises the last disk of fixedlying connected with left connecting rod and the lower disc of fixedlying connected with right connecting rod; Described upward disk and lower disc are hinged by hinge; Described hinge is fixed on the lower disc, and the described disk of going up is provided with the through hole corresponding with described hinge.
Further, be equipped with rectangular through slot along its length on described left sounding rod and the right sounding rod; Described left sounding rod and right sounding rod are expansion link.Rectangular through slot is convenient to observe and mark, and left sounding rod and right sounding rod are the measurement that expansion link can adapt to different big or small central portions, have enlarged measurement range.
Further, described center round platform, left round platform and right round platform are magnetic material and make.Adopt magnetic material to can be adsorbed on the metal parts such as steel, iron and avoided manually compressing, convenient and labor-saving.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model structural representation.
Embodiment
Further describe the utility model below in conjunction with specific embodiment and accompanying drawing.
A kind of survey instrument of definite center of circle as shown in Figure 1, comprises left connecting rod 21, right connecting rod 22 that center round platform and an end all are rotatably connected with it around the center of circle of center round platform; The other end of described left connecting rod 21, right connecting rod 22 is fixedly connected with left round platform 11, the right round platform 12 identical with described center round platform diameter respectively; The straight line at described left connecting rod 21, right connecting rod 22 places intersects at the center of circle of center round platform, and respectively by the center of circle of left round platform 11, the center of circle of right round platform 12; Perpendicular bisector by described left connecting rod 21, right connecting rod 22 is fixedly connected with left sounding rod 31, right sounding rod 32 respectively.
A left side connecting rod 21, right connecting rod 22 can be according to the size of tested central portion, the center of circle around the center round platform rotates to an angle, up to making center round platform, left round platform 11 and right round platform 12 all tangent with tested central portion, this moment, left sounding rod 31 was centers of circle of tested central portion with the intersection point of right sounding rod 32.Manufacturing and easy to adjust for convenience, left connecting rod 21 is consistent with right connecting rod 22 length.
Further, described center round platform comprises the last disk 14 of fixedlying connected with left connecting rod 21 and the lower disc 15 of fixedlying connected with right connecting rod 22; Described upward disk 14 is hinged by hinge 13 with lower disc 15; Described hinge 13 is fixed on the lower disc 15, and the described disk 14 of going up is provided with the through hole corresponding with described hinge 13.Simple in structure, realized that left connecting rod 21, right connecting rod 22 rotate around the center of circle of center round platform.
Further, be equipped with rectangular through slot along its length on described left sounding rod 31 and the right sounding rod 32; Described left sounding rod 31 and right sounding rod 32 are expansion link.Rectangular through slot when left sounding rod 31 intersects with right sounding rod 32 on it can form a diamond hole, is convenient to observe and the mark home position; The left sounding rod 31 of stretching structure and right sounding rod 32 can adapt to the measurement of large-size central portion, have enlarged measurement range.
Further, described center round platform, left round platform 11 and right round platform 12 are magnetic material and make.Adopt magnetic material to can be adsorbed on the metal parts such as steel, iron and avoided manually compressing, convenient and labor-saving.
