Problems solved by technology

[0002] During aircraft assembly or other assembly, sometimes the holes in the drawings are specified as multiple equidistant holes instead of specific sizes. At this time, workers need to measure the total length during operation, and then calculate the distance between every two holes. Then draw the line, and finally carry out the drilling operation according to the line. In this way, a lot of time is delayed when drawing the line, and the error is large, which is not conducive to improving production efficiency and is not conducive to the improvement of product quality.

Embodiment Construction

[0009] Such as figure 1 As shown, a kind of equidistant marking ruler is provided with elongated holes in the length direction of the ruler body 6 with scale, and the two ends of several movable rods 3 are respectively provided with positioning holes, and the movable rods 3 end and end pass through the hollow rotating shaft 2 Flexible connection, the center of each movable rod is provided with distance-adjusting rotating shaft 1, and each distance-adjusting rotating shaft 1 is positioned in the elongate hole of ruler body 6 successively.

[0010] Another group of end-to-end movable rods 3 is movably connected through the hollow rotating shaft 2, and the center of each movable rod 3 is alternately and symmetrically stacked with another group of corresponding movable rods 3, and they are jointly passed through the length of the distance adjusting rotating shaft 1 and the ruler body 6. Bar hole sliding connection.

[0011] The first distance-adjusting shaft 1 is connected to the...

Abstract

The invention relates to an equidistant scribing ruler. An elongated hole is formed in a ruler body provided with scales in the length direction. A positioning hole is formed at each end of each of a plurality of movable rods, heads and tails of the movable rods are movably connected through hollow rotary shafts, a distance-adjusting rotary shaft is arranged in the middle of each of the movable rods, and the distance-adjusting rotary shafts are disposed in the elongated hole successively. By means of the equidistant scribing ruler, the scribing time is shortened, the scribing quality of a product is improved, and drilling can be completed efficiently and accurately.

Description

technical field [0001] The invention relates to an equidistant line marking ruler, which is used as an auxiliary tool for line drawing work in the early stage of mechanical processing. Background technique [0002] During aircraft assembly or other assembly, sometimes the holes in the drawings are specified as multiple equidistant holes instead of specific sizes. At this time, workers need to measure the total length during operation, and then calculate the distance between every two holes. Then carry out scribing and drawing, and finally carry out the drilling operation according to the scribing, so that a lot of time is delayed when drawing the line, and the error is large, which is not conducive to improving production efficiency and is not conducive to the improvement of product quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an equidistant marking ruler, which not only shortens the drawing time, but...
