Abstract
A kind of conical section divider calipers, compasses device mainly comprises bearing, dynamic x-axis, determines x-axis, slide rail, moves some box and rope, a dynamic some box device mainly comprise upper driving wheel, friction pulley, drive link and under pass, move x-axis, determine x-axis, slide rail, be arranged on bearing, dynamic some box is arranged in dynamic x-axis, determine x-axis to be connected by rope with dynamic some box, friction pulley is arranged on drive link, and upper driving wheel lower driving wheel is connected with drive link by friction pulley.The utility model has: the advantages such as structure is convenient, simple to operate, and mapping is accurate, with low cost.
Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of conical section divider calipers.
Background technology
Draw with rope as everyone knows that oval traditional method can easily the ellipse that draws of movement be inaccurate due to rope two ends, end positions also not easily draws, and the ellipse drawn by ruler method is also accurate not; And for hyperbola and parabola, the teaching aid also lacking a kind of specification can draw figure exactly, in study, bring a lot of inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of conical section divider calipers.
The utility model compasses device mainly comprises bearing, dynamic x-axis, determines x-axis, slide rail, moves some box and rope, a dynamic some box device mainly comprise upper driving wheel, friction pulley, drive link and under pass, move x-axis, determine x-axis, slide rail, be arranged on bearing, dynamic some box is arranged in dynamic x-axis, determine x-axis to be connected by rope with dynamic some box, friction pulley is arranged on drive link, and upper driving wheel, lower driving wheel are connected with drive link by friction pulley.
Be fixed on blackboard by four pin of bearing during use, determine the position of focus and the length of semi-major axis, dynamic some box regulates the position of friction pulley to determine the size of eccentricity, mobile dynamic some box just can draw required conic section.The movement locus of dynamic some etui is that some boxes move along rope and along the resultant motion moving x-axis, there is stepless speed change device the inside, realizes infinitely variable speeds with friction pulley.This teaching aid should make some boxes along the speed of dynamic x-axis and move the ratio continuously adjustabe of some box along the speed of rope, and this ratio is realized by friction pulley.When friction pulley is at corresponding gear, i.e. eccentricity e=1, now the angular speed of friction pulley is certain, then the linear velocity contacted with upper and lower two-wheeled is identical, can obtain dynamic some box along the speed of speed=dynamic some box along rope moving x-axis; In like manner can obtain different eccentricity e by friction pulley.
Compared with the prior art, the beneficial effects of the utility model are: structure is convenient, simple to operate, and mapping is accurately, with low cost.
accompanying drawing explanationfig. 1 is stereochemical structure sketch of the present utility model.Fig. 2 is dynamic some cassette interior schematic diagram.
detailed description of the inventionin the stereochemical structure sketch of the present utility model shown in Fig. 1, mainly comprise bearing 1.1, dynamic x-axis 1.2, determine x-axis 1.3, slide rail 1.4, dynamic some box 1.5, rope 1.6, move x-axis 1.2, determine x-axis 1.3, slide rail 1.4, be arranged on bearing 1.1, a dynamic some box 1.5 is arranged in dynamic x-axis 1.2, determines x-axis 1.3 and is connected by rope 1.6 with a dynamic some box 1.5.
In the dynamic some cassette interior schematic diagram that Fig. 2 looks, mainly comprise upper driving wheel 2.1, friction pulley 2.2, drive link 2.3 lower driving wheel 2.4, friction pulley 2.2 is arranged on drive link 2.3, and upper driving wheel 2.1, lower driving wheel 2.4 are connected with drive link 2.3 by friction pulley 2.2.
