Abstract
The present invention relates to a measuring scale for taper angle. It can be used for directly measuring cone or taper angle of taper hole. When using, the taper angle of cone can be directly indicated on its main scale. Said invention has a higher accuracy, not only can measure independent cone body, but also can measure the cone body fixed on other material, and said invention can measure inner cone body (taper hole) as well as outer cone body.
Description
The present invention relates to a kind of cone-angle measure gauge, it can directly be measured the cone angle of cone or taper hole.
The method that has the cone angle of measuring cone now is a lot, and facing-up method, sine protractor mensuration, steel ball garden post mensuration and video method etc. are arranged.Wherein, the facing-up method is by checking the situation that contacts on gauge surface and measured piece surface, and as the number percent of painted homogeneity, contact area etc., with the cone angle of visual observation judgement measured piece, this method is easy and simple to handle, but precision is not high; The precision of sine protractor mensuration, steel ball garden post mensuration and video method is higher, but also has some shortcomings: 1, will just can draw the cone angle data by calculating, speed is slow, and efficient is low; 2, can only measure independently measured piece, energy measurement is not fixed on the measured piece on other object; 3, can only measure Outer Taper, not energy measurement inner cone (being taper hole).Above measuring method is referring to China Measuring Press's " length metering technology question and answer " (October nineteen ninety).
It is 1 ' (being the sixtieth degree) cone-angle measure gauge that task of the present invention provides a kind of precision, and it is easy and simple to handle, can directly read the cone angle number of degrees of cone, can measure the independent part of surveying, and can measure the measured piece that is fixed on other objects again; Both Outer Taper can be measured, inner cone (being taper hole) can be measured again.
The present invention is achieved in that the fixedly connected top of deciding bar of the starting point end on a main scale, should decide the top of the terminal of bar and a working beam hinged, the stage casing of deciding the stage casing of bar and a moving bar is hinged, the top of moving bar connects a vernier that slides only on main scale, the terminal of moving bar and the top of another working beam are hinged, article two, the equal in length of working beam, their terminal is hinged with two two terminals at the interior working beam of the hinged equal in length of midpoint crossing respectively, two tops of these two interior working beams are hinged on respectively to be decided on bar and the moving bar, wherein, decide the distance of the hinged pin joint of bar and moving bar to the distance of deciding the bar terminal and this pin joint to the terminal of moving bar equal in the length of working beam, half of working beam length in the length of working beam equals.
The present invention is owing to the cone angle of directly indicating cone on main scale, and is therefore very easy to use, and has higher precision, both can measure independently cone, can measure the cone that is fixed on other objects again; Both Outer Taper can be measured, inner cone (taper hole) can be measured again.
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is a structural representation of the present invention.
As shown in Figure 1, at the fixedly connected top of deciding bar 2 of the starting point end of main scale 1, should decide the top of the terminal of bar 2 and working beam 5 hinged, the stage casing of deciding bar 2 stage casings and a moving bar 3 is hinged, pin joint is A, the top of moving bar 3 connects a vernier 4 that slides only on main scale 1, the terminal of moving bar 3 and the top of working beam 6 are hinged, working beam 5 and 6 terminal are hinged with the terminal of interior working beam 7 and 8 respectively, interior working beam 7 and 8 equal in length, their mid point is hinged, and their two tops are hinged on moving bar 3 respectively and decide on the bar 2, wherein, pin joint A equates to the distance of moving bar 3 terminals with pin joint A to the distance of deciding bar 2 terminals, and working beam 7 or 8 length in equaling, and the equal in length of working beam 5 and 6, and equal half of length of interior working beam 7 or 8, in the present embodiment, each lattice is represented 1 ° in the scale on the main scale 1, and the scale of vernier 4 has 60 little lattice, and each little lattice angle value is 59 '.During use,, can be close to interior working beam 7 and 8 two side bus of this cone if measured piece is Outer Taper, just can on main scale 1 and vernier 4, read and be accurate to 1 ' the cone angle number of degrees; If by part is inner cone (taper hole), then working beam 5 and 6 is close to the bus of inner cone, also can read the inner cone coning angle number of degrees.
