Abstract
The utility model relates to a tool for measuring and testing the radius and the angle of an external circular arc, which comprises a circular arc support frame and at least three rulers arranged on the support frame along the radial direction and are movably matched with the radial direction of the support frame, wherein, at least two rulers are movably matched with the support frame on the circular arc direction. The utility model is completed according to the principle that the three points on the circular arc are utilized to realize the determination of the center of circle according to that the distance between the center of circle and each point on the circular arc. The utility model has the advantages of simple structure, low cost, and convenient operation.
Description
The utility model is a kind of instrument of measuring verification outer arc radius and angle.
In many production fields such as machine-building, processing, mapping, often need to measure the radius and the angle of verification external arc.As measure the arcwall face or the protruding sphere of verification part.All do not have good measuring method and instrument in this respect always, and generally adopt instruments such as radius gauge (arc rule) or projector to realize that it is very loaded down with trivial details to operate, the measurement expense height, and measure inaccurately, measurement data is discontinuous.Sometimes adopt tool microscope, bow Gao Yi, arc to cut tool operations such as instrument, but will pass through loaded down with trivial details calculating, and on-the-spot practicality is not strong.
The purpose of this utility model is: design a kind of simple in structure, the measurement school verification outer arc radius of processing ease and the instrument of angle.
The utility model comprises arc stent and is installed in support along radially and with support the forming at movingly at least three rulers radially of support, and wherein at least two rulers and support are in the circular arc direction movingly.
The utility model is according to the distance of center of circle each point to the circular arc, utilizes on the circular arc 3 realizations that the principle of determining in the center of circle is finished.Move three rulers in use, its inner all is positioned on the circular arc, adjust three ruler the inners again and equate, deduct the length of ruler in support, then draw by the radius of side circular arc by the radius of support to the distance on the support.During measurement, if the both sides ruler in the outside is positioned at the outer end of circular arc, then the angle of both sides chi is the angle of circular arc.The utlity model has simple in structure, with low cost, convenience operation.
The connected mode of the utility model ruler and support can be: the chi frame is installed on the support, and each ruler is loaded in the radial slot on its chi frame.The chi frame can be moved along support, and ruler can be done radial motion along the chi frame, its concrete structure can be: the support cross section is dovetail shaped, the shape of groove one side that the chi frame is gone to the bottom is consistent with the shape of support cross section one side, another part of groove is equipped with compact heap, and the adjusting bolt that passes compact heap is connected with the chi frame.And the thickness of compact heap can be less than the degree of depth of groove, between bolt and the compact heap spring is arranged.
But the cross section parallelogram of the groove in the utility model on the chi frame, the compact heap side view is corresponding with the shape that support reaches the groove that cooperates with it.
In addition, on a chi frame that is positioned at the outside, can also be shaped on the angle scale of support arc unanimity with it.
For the utility model is measured accurately, the inner of each ruler is preferably pointed.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the A-A view of Fig. 1:
Fig. 3 is the B-B view of Fig. 1;
Fig. 4 is the C-C view of Fig. 1;
Wherein, 1-side chi, the 2-support, 3-chi frame, chi among the 4-, the 5-clamping screw, 6-side chi, the 7-angle scale, the 8-compact heap, 9-regulates bolt.
As shown in the figure, present embodiment comprises that circular arc, end face are trapezoidal support 2, and three identical chi framves are installed on the support 2.With middle chi chi frame 3 is example, has on its bottom surface that a side with a side stand 2 adapts, the groove of cross section parallelogram, and support 2 is arranged in groove, and its corresponding limit cooperates.Between the another side of the groove on support 2 and the chi frame 3 compact heap 8 is housed.The thickness of compact heap 8 has the adjusting bolt 9 that cooperates with spring to pass compact heap 8 and spins with chi frame 3 less than the degree of depth of groove on it.The upper surface of chi frame 3 has along support 2 dovetail groove radially, and inner pointed middle chi 3 is a ruler, and it is loaded in the groove on the chi frame 4, and there is clamping screw 5 side of chi frame 3.The version of two side chis 1,6 and chi frame thereof is identical with middle chi 3.Be fixed with in the outside of a chi frame of a side chi 6 and have angle scale 7 angle index and consistent with support 2 arcs.
When using the utility model, joined the Youth League on any 3 of measured circular arc in the inner of three rulers, the inner of regulating three rulers is equal to the distance of circular arc support, at this moment, orthodrome shown in measured circular arc and the support is a concentric circles, and the difference of the inner distance to support of support radius and three rulers is the radius of measured circular arc.The clamping screw of three rulers is tightened, regulate the angle of two side chis, make two end points of the inner of two side chis corresponding to measured circular arc, the adjusting bolt of the compact heap of middle chi and side chi is tightened, can on support upper angle scale, read angle, and the angle scale on the side chi can make angular readings more accurate.For the verification of external arc, can be earlier the arc radius angular adjustment of side chi directly be stuck on the circular arc after accurately and carries out.
