Description

I

Coordinate drawing machines are known which contain a fixed horizontal rail with a sliding, mounted in the upper part of the drawing board, a vertical rail, a supporting carriage, and a turntable drawing ruler.

The purpose of the invention is to expand the range of tasks.

This is achieved by the fact that the proposed coordinate drawing on the machine is provided with a second horizontal guide with a slider fixed in the lower part of the board, a second vertical guide with a carriage and a rotary disk mounted on the carriages of the vertical guides, while both vertical guides are rigid. horizontal guide guides, and the drawing ruler is attached to the turntable and carries a slide with the drawing tool.

The drawing schematically shows the proposed coordinate drawing machine.

The drawing maple consists of horizontal guides 1 and 2 with sliders 3 and 4 which cannot move along them, to which vertical guides 5 and 6 are rigidly attached. Between the carriages 7 and 8, which move along the vertical guides, the fixed disk 9 is divided with divisions . Inside the non-moving disk, there is a rotating disk 10 with a drawing ruler and a slider 12 on which the drawing tool 13 is fixed. For ease of movement, the balls 14 are placed between the fixed and rotating disks. The drawing drawing board is punctured onto the board 15.

By moving the slider 12, with the help of the tool, the lines (risks) are drawn in the plane of the outline, and the length of the line is maintained along the ruler. The angle of inclination is discolored by means of a rotary disk mounted relative to a movable disk on which divisions are applied. Dugi Okrul posts are traced with a disk 10 turn.

The value of the radius depends on the displacement of the slider with the drawing tool relative to the rotating disk, the movement of which with a ruler along the guides 1, 2, 5 and 6 ensures the construction of direct and arcs

anywhere on the drawing board.

Subject invention

A coordinate drawing machine containing a stationary horizontal nanowire with a slide, mounted in the upper part of the drawing board, a vertical guide, a carrier carriage, and a rotary drawing ruler, characterized in that, in order to expand the range of tasks to be solved, it is equipped with a second horizontal guide with a slider fixed in the lower part of the mowing, a second vertical guide with a carriage and a rotatable bottom of the board, a second vertical guide, with both verticals4

The guide rails are rigidly attached to the sliders of the horizontal guides, and the drawing ruler is fixed in the turntable and carries the slide with the drawing tool.
