Description
Известен способ вычерчивани предметов в аксонометрических проекци х, например изометрических, по двум ортогональным проекци м и чертежный прибор дл осуществлени этого способа, включающий две соединенные под углом линейки, одна из которых укреплена подвижно по отнощению к другой с возможностью установки под требуемым углом, отсчитываемым по градусной щкале с нониусом.There is a known method of drawing objects in axonometric projections, for example isometric, along two orthogonal projections and a drawing device for carrying out this method, including two angled rulers, one of which is fixedly movable relative to the other and can be installed at the required angle, measured by degree scale with nonius.
Предлагаемый способ позвол ет ускорить, в сравнении с известным , процесс вычерчивани предметов в аксонометрических проекци х, дл чего чертежи ортогональных проекций предмета прикрепл ют под углом к горизонту, а именно: чертеж главного вида под углом в 45°, а чертеж вида сверху под углом в 105°. Линейки чертежного прибора устанавливают под углом в 120°, смещают прибор параллельно самому себе так, чтобы кромки соответствующих линеек последовательно совпадали с проекци ми точек пред.мета на прикрепленных чертежах. После этого в верщине угла, образованного линейками прибора, отмечают изометрическую проекцию точки.The proposed method allows speeding up, in comparison with the known, the process of drawing objects in axonometric projections, for which the drawings of the orthogonal projections of the object are attached at an angle to the horizon, namely: the main view drawing at an angle of 45 ° and the top view drawing at an angle at 105 °. The drawing device rulers are set at an angle of 120 °; the device is displaced parallel to itself so that the edges of the respective rulers consistently coincide with the projections of the grid points on the attached drawings. After that, in the vertex of the angle formed by the instrument lines, an isometric projection of a point is noted.
Предлагаемое устройство можно применить на чертежном комбайне , дл чего оно снабжено фигурным рычагом, а его линейки выполнены раздвижными. При это.м шкала нанесена на фигурном рычаге, один конец которого прикреплен к неподвижной линейке, а другой - к чертежному комбайну.The proposed device can be used on a drawing combine, for which it is equipped with a figured lever, and its rulers are made sliding. With this, the scale is applied on a figured lever, one end of which is attached to a fixed ruler, and the other to a drawing combine.
Па фиг. 1 схематически изображен предлагаемый чертежный прибор; на фиг. 2 и 3 - примеры построени аксонометрических проекций.Pa figs. 1 schematically shows the proposed drawing device; in fig. 2 and 3 are examples of the construction of axonometric projections.
Прибор состоит из двух раздвижных линеек 1 2, которые посредством фигурного рычага 5 с нанесенной на него щкалой креп тс кThe device consists of two sliding rulers 1 2, which are fastened to the
№ 144605- 2 головке чертежного комбайна. Линейка / неподвижна и на доске занимает вертикальное положение, а подвижна линейка 2 поворачиваетс под требуемым углом к линейке 1, определ емом по шкале на фигурном .рычаге 3.No. 144605- 2 to the head of the drawing combine. The ruler / is stationary and on the board occupies a vertical position, and the movable ruler 2 rotates at the required angle to ruler 1, which is determined on a scale on the figured lever 3.
Длина линеек может измен тьс в зависимости от размеров аксонометрического изображени .The length of the rulers may vary depending on the size of the axonometric image.
Прибор работает следующим образом.The device works as follows.
Чертежи главного вида и вида в плане предмета, аксонометрическую проекцию которого надо изобразить, креп тс к чертежной доске под соответствующим углом к горизонту, а линейка 2 устанавливаетс по щкале рычага 3 под требуемым углом к линейке 1.The drawings of the main view and the plan view of the object, the axonometric projection of which is to be drawn, are attached to the drawing board at a corresponding angle to the horizon, and the ruler 2 is installed on the slider of the lever 3 at the required angle to the ruler 1.
Кромка линейки / подводитс к горизонтальной Л, а кромка линейки 2 к вертикальной А проекци м точки Л, затем смещают прибор при помощи трансл тора комбайна параллельно самому себе так, чтобы кромки линеек прибора подощли к проекци м BI и BZ следующей точки В оп ть-таки в верщине угла, образованного линейками (см. фиг. 2 и 3) и т. д. Полученные проекции точек попутно соедин ют пр мыми лини ми и получают контур предмета.The edge of the ruler / goes to the horizontal L, and the edge of the ruler 2 to the vertical A projections of the point L, then displace the device using a combine translator parallel to itself so that the edges of the ruler lines of the device support the projection BI and BZ of the next point B again- however, in the vertex of the angle formed by the rulers (see Figs. 2 and 3), etc. The resulting projections of the points are simultaneously connected by straight lines and get the outline of the object.
Если на ортогональных проекци х нанесены разрезы, то они автоматически перенос тс на аксонометрическое изображение в процессе построени последнего.If cuts are made on orthogonal projections, they are automatically transferred to the axonometric image during the construction of the latter.
Прибор отличаетс простотой конструкции и при серийном изготовлении будет стоить дещево.The device is distinguished by its simplicity of design, and during mass production it will cost too much.
Построенные при помощи прибора аксонометрические изображени отличаютс точностью, а его применение на чертежном комбайне расшир ет область применени последнего.The axonometric images constructed with the help of the device differ in accuracy, and its use on a drawing combine expands the field of application of the latter.
