Description

  The present invention relates to a general-purpose tool that divides a workpiece at an arbitrary angle around a reference point by using line light.

  Conventionally, in order to divide a workpiece at an arbitrary angle around one point, it is necessary to measure the angle from the center using a ruler, a compass or the like, and then perform marking and division work. In particular, dividing the work piece into arbitrary odd numbers such as 5 or 7 is accompanied by the above-mentioned work or requires a dedicated tool on which a required number of divisions are marked in advance.

    The problem to be solved is that the process of measuring and determining the angle is complicated when the work piece is divided at an arbitrary angle around a single point as a reference. It is an object to provide a tool that can be easily obtained.

  The present invention uses a line laser and a mirror to irradiate a workpiece with line light that intersects at an arbitrary angle, and uses the irradiated line light as a mark so that the workpiece is used as a reference. The main feature is to facilitate the work of dividing into an arbitrary angle.

  The present invention can be visually observed by irradiating line light without being restricted by the shape, color, material, and state of the workpiece to be divided, and the conditions such as the presence of environmental light and air. And always provide accurate guidelines.

In the present invention, the angle of the mirror for turning back the line light is made variable and simple angle setting means is provided, so that it is possible to easily set an arbitrary division angle and an arbitrary number of divisions.

Since the present invention can attach any tool such as a pointed or rotating blade or a tool or pen having a blade or a needle, or a needle to the line light generator and the holder, such as cutting, marking, or engraving, A wide range of machining operations can be handled.

  The objective of being able to divide the workpiece easily with any number of divisions and any angle has been realized.

  FIG. 13 shows an embodiment of the tool of the present invention, which is an instrument having a mirror fixed to a line laser and a rotating mirror holder, a holder, and a rotary blade.

  4, 5, 6, 7, 8, 9, 10, and 11, the process of equally dividing the workpiece 12 into an arbitrary number around a single point will be described.

  First, the number to be divided is determined, the mirror holder 8 is rotated, and the scale 9 and the dial 11 are adjusted to the number to be divided. FIG. 4 shows the state of the dial and the scale when dividing into 5 parts, and an arbitrary reflection angle 7 is held at 72 degrees by the latch 10.

Next, according to FIG. 5, the rotary blade 16 is pressed against the division center point 20 of the circular workpiece. Next, according to FIG. 6, the rotary blade is pushed all the way to the outer periphery to generate the first dividing line 21 from the center point.

  Next, according to FIG. 7, the line laser 1 is caused to emit light, and the perpendicular line 13 of the line light is aligned with the division center point 20 of the workpiece. Then, near the rotary blade, the line light 4 parallel to the traveling direction of the rotary blade and the folded line light 5 having the set arbitrary reflection angle 7 are irradiated to the workpiece. The direction of the holder 14 is adjusted so that the folded line light 5 overlaps the first dividing line 21. Thereafter, as shown in FIG. 8, the second dividing line 22 is generated by pushing the rotary blade in the outer peripheral direction of the workpiece.

  Further, referring to FIG. 9 and FIG. 10, the third dividing line 23 is obtained by performing the same operation, and the same operation is repeated thereafter. FIG. 11 shows a state where the five divisions are completed.

  In this way, the workpiece can be easily divided at an equal angle by simply combining the line light 5 that is turned back with respect to the previous dividing line and processing in the direction indicated by the line light 4. This is particularly effective when it is desired to obtain an odd number of equal divisions such as five divisions and seven divisions.

  Since it is not restricted by the work piece or the environment, it can be used for division of circular foods such as pizza and cake, drafting and work, or work in outer space.
