Description
Известны приборы дл вычерчивани эллипсов, выполненные в виде плоской коробки, снабженной кривошипным механизмом, взаимодействующим с ползунком, несущим пишущее острие.Instruments for drawing ellipses are known, made in the form of a flat box equipped with a crank mechanism interacting with a slider that carries a writing point.
Недостатком этих приборов вл етс невозможность получени точных очертаний эллипса.The disadvantage of these devices is the impossibility of obtaining accurate outlines of the ellipse.
В предлагаемом приборе этого недостатка нет. Это достигаетс применением коромысла, несущего по концам две кулисы, взаимодействующие: одна с пальцем кривошипа, а друга - с ползунком пишущего остри .In the proposed device this lack is not. This is achieved by using a rocker arm carrying two wings at the ends, interacting: one with the finger of the crank, and the other with the slider of the writing point.
Дл осуществлени переменной установки оси коромысла на различиый эксцентрицитет эллипса в приборе может быть применена перемещающа с в направл ющих пазах коробки пластина. Последн имеет продольные прорези дл укреплени оси коромысла и две поперечные прорези дл взаимодействи с пальцем кривошипа и ползупком пищущего остри .To implement a variable setting of the axis of the rocker on the different eccentricity of the ellipse in the device, a plate moving in the guide slots of the box can be used. The latter has longitudinal slits for reinforcing the axis of the rocker and two transverse slots for interacting with the crank pin and the snapping point of the squeegee.
На фиг. 1 и 2 изображен в двух проекци х предлагаемый прибор дл вычерчивани эллипсов; на фиг. 3 -устройство коробки прибора; на фиг. 4 - пластина прибора.FIG. 1 and 2 are shown in two projections of the proposed device for drawing ellipses; in fig. 3-device device box; in fig. 4 - plate device.
Предлагаемый прибор дл вычерчивани эллипсов выполнен в виде плоской коробки 1, снабженной кривошипным механизмом 2, взаимодействующим с ползунком 3, несущим пишущее острие 4. Коромысло 5 несет по концам две кулисы (5 и 7, взаимодействующие: перва с ползунком 3 пищущего остри 4, а втора -с пальцем 8 кривощипа 9. Пластина 10, перемещающа с в направл ющих пазах 11 коробки, снабжена продольными прорез ми 12 и 13 дл укреплени оси 14 коромысла и двум поперечными прорез ми 15 и 16 дл взаимодействи с пальцем 8 и ползунком 3.The proposed device for drawing ellipses is made in the form of a flat box 1, equipped with a crank mechanism 2, which interacts with a slider 3, carrying a writing tip 4. The beam 5 carries two wings at the ends (5 and 7, interacting: the first with a slider 3 of the food tip 4, and the second with the finger 8 is crank 9. The plate 10 moving in the box guide grooves 11 is provided with longitudinal slots 12 and 13 for reinforcing the axis 14 of the rocker arm and two transverse slots 15 and 16 for engaging with the finger 8 and the slider 3.
№ 147323-2Вычерчивание эллипса производитс следующим образом.No. 147323-2 The ellipse traversing is done as follows.
Пластина 10 вынимаетс из пазов // и палец 8 устанавливаетс на кривошипе в положении, соответствующем величине большой полуоси эллипса. Затем ось коромысла 5 устанавливаетс на пластине 10 по шкале 17 в положение.соответствующее эксцентрицитету вычерчиваемого эллипса. Затем пластина 10 вставл етс в пазы // коробки / и прибор подготовлен к вычерчиванию эллипса. Далее прибор накладываетс на чертеж так, чтобы .перекрытие штрихов визирной планки 18 совпало с центром вычерчиваемого эллипса, а сами щтрихи совпали с направл ющими большой и малой осей эллипса. После этого визирна планка вынимаетс , а кривошип 9 поворачиваетс на 360°. Пишущее острие 4 при этом вычертит эллипс.The plate 10 is removed from the grooves // and the finger 8 is mounted on the crank in a position corresponding to the magnitude of the major semi-axis of the ellipse. Then, the axis of the rocker arm 5 is set on the plate 10 on a scale of 17 to a position corresponding to the eccentricity of the ellipse being drawn. Then, the plate 10 is inserted into the grooves / boxes / and the device is prepared to draw an ellipse. Further, the device is superimposed on the drawing so that the overlap of the strokes of the reticle 18 coincides with the center of the ellipse being drawn, and the lines themselves coincide with the guides of the major and minor axes of the ellipse. Thereafter, the target plate is removed, and the crank 9 rotates 360 °. The writing tip 4 at the same time draws an ellipse.
Промышленна полезность предложени подтверждена луганским горно-металлургическим институтом, где прибор испытан -с положительными результатами.The industrial utility of the proposal was confirmed by the Lugansk Institute of Mining and Metallurgy, where the device was tested with positive results.
