A mechanical arm type precision circle drawing device

Abstract

The invention discloses a mechanical arm type precise circle-drawing device. The mechanical arm type precise circle-drawing device comprises a drawing board, a precise circle-drawing mechanism, an orienting mechanism, a foldable baffle mechanism and a retractable mechanism arm, wherein the orienting mechanism is arranged at the top corner of the upper portion of the drawing board; the retractable mechanical arm is disposed on the orienting mechanism; the precise circle-drawing mechanism is mounted at the end of the retractable mechanical arm; the foldable baffle mechanism is disposed at the bottom of the drawing board. By means of the mechanical arm type precise circle-drawing device, any circle and any circular arc can be drawn precisely in any position of the drawing board, and various tools required for drawing can be omitted; the mechanical arm type precise circle-drawing device is light and exquisite in design, convenient to carry and use and precise in structure; the drawing precision and the drawing efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a circle drawing device which reduces the carrying of multiple circle drawing tools, is simple to operate, and can realize fast and accurate circle drawing. Background technique [0002] At present, with the increasing abundance of computer graphics software, a large number of two-dimensional and three-dimensional graphics software has been popularized. However, in engineering colleges or industrial enterprises, the drawing tablet is still an important tool for basic manual drawing, and it is even more indispensable for mechanical students. Due to the simple structure of the traditional drawing device, the functions that can be realized are relatively single, and there are many problems in the drawing process. At present, the drawing board is made of wooden material. Considering its production cost, the wood is generally soft. During use, due to the friction between the T-square and the side or the collision between the side a...

Problems solved by technology

Due to the simple structure of the traditional drawing device, the functions that can be realized are relatively simple, and there are many problems in the drawing process.

At present, the drawing board is made of wooden material. Considering its production cost, the wood is generally soft. During use, due to the friction between the T-square and the side or the collision between the side and a hard object, the reference side of the drawing board is easily fluffed or damaged, and it is not easy to With scales, it affects normal use. When drawing a circle, you need to use compasses, pencils, scotch tape, etc. The placement and carrying of these tools has become a problem

Of course, there are also some drawing devices, which also have various problems in the use of functions, such as: they cannot draw circles with arbitrary diameters, circles with arbitrary reference positions, and they are bulky and not easy to carry.
