An equal ruler for log processing

Abstract

The invention discloses a uniform scale used for log processing. The uniform scale comprises an equalizer, a spring nail, a thread rope and a pen wire box. A shape of the equalizer is the same with a shape of a protractor and a center is provided with a hollow screw. A surface and an outer edge of the equalizer are provided with uniform scale lines. A cut-off point of the uniform scale lines of the surface is provided with a dot hole. The spring nail and the hollow screw are assembled in a matching mode. The spring nail and the pen wire box are connected through the thread rope. The uniform scale of the invention has advantages that equalizer scales are converted into equalization scales from an angle; a center position is fixed through the spring nail; usage is rapid and accurate; through application of the pen wire box, the uniform scale can be suitable for a large log size; the pen wire box can uniformly and accurately dots when an angle of the pen wire box and the thread rope is within 90 degree; and each main component of the uniform scale can be dismounted and installed at any time so that replacement is convenient.

Description

technical field [0001] The invention relates to a measuring tool, in particular to an aliquot used for log processing, which is suitable for processing circular components such as cylinders in wooden tenon structures. Background technique [0002] At present, in the processing of logs of components such as columns in the tenon structure, the selected round logs are mainly selected according to the type of the column, and according to the upper and lower ends of the growth of the wood, the column head and the foot of the column are determined to be padded with wooden pads, and separated on the diameter surfaces of both ends. At the midpoint, hang the center line and divide it on this line, draw the cross center line with a square ruler, on this basis, place the eighth equal line at the base of the column according to the designed column diameter, and place the column head at 7 / 1000 or 7 / 1000 of the designed column height 10 / 1000 points and puts the eighth equal line, accordin...

Problems solved by technology

Among them, the depiction of the equisector relies on the current protractor on the market, and its scales are all in degrees. When positioning, the angle needs to be calculated. The calculated angles are not all integers. The positioning of the sub-line is not only troublesome and time-consuming, but also has low accuracy
