Embodiment Construction

[0020] Provide specific embodiments below in conjunction with accompanying drawings. One embodiment of the present invention is to draw an ellipse in a vertical plane, as shown in the figure, the large suction cup (14) is tightly adsorbed on the vertical plane, the whole device is placed stably, and the threaded sleeve (5) is adjusted Combine the length with the adjustable screw rod (6) to reach the required size, switch on the power supply of the motor (8), and make it start running, so that the horizontal axis slide block (17) and the vertical axis slide block (19) are in the maximum Slide in the chute (16), and then draw the curve with the animation pen (3). When the vertical axis slider moves to the cross center of the large chute (16), the electromagnet along the positive or negative direction of the vertical chute (11) electrify, make it produce magnetism, thereby produce a force along vertical groove positive direction or negative direction to the small iron block (12) ...

Abstract

The invention relates to an ellipse drawing device, and belongs to the field of mechanical engineering. In order to overcome the defects of a traditional ellipse drawing device, the invention discloses a lead screw type ellipse drawing device. The lead screw type ellipse drawing device is characterized in that a ball screw mechanism is used for driving slide blocks to move in a cross chute, so that a drawing pen connected to the tail ends of extension arms on two slide blocks is driven to draw an ellipse. The lead screw type ellipse drawing device has the following advantages: (1) the lead screw structure is used for driving the slide blocks, so that the drawing process is stable, and drawn patterns are more smooth and beautiful; (2) a screw rod cooperates with a thread sleeve, so that theextension arms are adjusted more conveniently; and the screw rod is provided with scales for precisely adjusting the size of the ellipse; and (3) the structure is simple; the drawing speed is controllable; and actual operation and teaching demonstration are convenient.

Description

technical field [0001] The invention relates to an ellipse drawing device, which belongs to the field of mechanical engineering, in particular to a plane ellipse drawing method and equipment thereof. Background technique [0002] At present, most of the drawing tools can only draw straight lines and circles. The drawing of ellipses has always been one of the focuses of research and is often used in engineering surveying and daily teaching. Most of the existing ellipse drawing instruments stay at the level of simple manual drawing tools, and most of them have defects such as complicated drawing process, small drawing size, slow drawing speed, and inconvenient teaching and demonstration. [0003] In order to overcome the inconveniences of existing ellipse drawing devices, the invention discloses a plane ellipse drawing instrument and drawing method which are simple and easy to implement, convenient to demonstrate, stable and reliable to draw, fast to draw, and have a large adj...
