Abstract

PROBLEM TO BE SOLVED: To provide a sawing apparatus wherein operation can be exactly, quickly and safely carried out along a cutting mark applied to a part to be cut by sawing in technical fields such as not only lumber processing for building but also cutting various materials by sawing. SOLUTION: A laser beam oscillator 1 for positioning which is fixed to a part just above and opposed to a part 7 to be cut by sawing by putting saw blade 6 between them and a rod lens 2 are provided. By radiating laser beams 3 as linear beams 4 with the rod lens 2, the part 7 to be cut by sawing is projected as two lines 5 and 5 on the part 7 to be cut by sawing. The sawing apparatus is adjusted while this line is adjusted to the cutting mark and saw-cutting operation is carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sawing machine for building timber processing, and more particularly, to aligning a beam line of this machine with a cutting ink provided in various directions and angles at a part to be sawed in a working process. By setting, the cutting operation can be performed accurately, quickly and safely, and the cutting position and direction are always indicated, so that the device can be cut smoothly. It can be used in the technical field of sawing equipment for various steel materials and plastics, including the construction field of sawing wood.

[0002]

2. Description of the Related Art When cutting wood or the like with a conventional wood processing sawing device, the direction and angle of the saw blade are set, and then the saw blade is directly applied to the cutting ink applied to the cut portion. And positioning and cutting. In addition, there were sawing machines and cutting machines equipped with a dimension positioning device that adjusts the laser beam to the cutting dimension line, but the beam was projected only in a point shape, making it difficult to set various cutting directions and cutting angles for the saw blade. was there.

[0003]

The problem with these methods is that the beam to be cut is generally only applied to the cut portion in a point-like manner. In other words, conventional cutting machines require a high level of technical skill and labor to perform cutting work accurately and quickly and safely along cutting ink in various directions and angles attached by craftsmen. There were many cutting failures and waste of cutting materials.

[0004] An object of the present invention is to solve the above problem by projecting a cutting progress line of a saw blade to a cut portion by a linear beam, so that a saw blade is attached to the cut portion. Is to provide a device that cuts accurately, is safe in operation, and can easily set the direction and angle of the cutting machine.

[0005]

Means for Solving the Problems In order to achieve the above-mentioned object, as a means for obtaining a linear beam, a round lot lens is set at the tip of a laser beam emitted from a laser oscillator. At the time of transmission, a linear beam perpendicular to the long axis of this lens is obtained

[0006] A laser irradiation type apparatus that solves the problems of the conventional cutting apparatus by utilizing such features of the present laser beam and the lot lens. A laser beam oscillator directly above and a lot lens that converts a beam emitted from the laser beam into a linear beam.The width of the linear beam can be adjusted by adjusting the diameter of the beam emitted from the oscillator. It is characterized by.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, with reference to the drawings, a specific description will be given of an example of a tabletop circular saw equipped with a saw blade positioning device using a linear beam for wood processing according to the present invention.
The cutting device itself in the drawing is a schematic view of a tabletop circular saw that has been conventionally used by carpenters and craftsmen. A hood for protecting the safety from the blade, 7 is a square material to be cut.

FIG. 1 shows a configuration diagram of the present invention, wherein 1 is a red laser oscillator, and 2 is a lot lens.
The laser beam 3 emitted from the laser oscillator becomes a linear beam as shown in the figure while passing through the lot lens 2, making the diameter of the beam 3 larger than the thickness of the saw blade and in a direction parallel to the side surface of the saw blade. By irradiating from above, the irradiated beam is cut in half by the just circular saw blade, and is radiated to the cut portion as two lines 5, 5 '.

[0009] The lines projected as the two parallel lines of the material to be cut are matched with the cutting ink. In addition, the width of the two lines and the width of the line are just the cutting margin of the saw blade.

[0010] As described above, when the laser oscillator and the lot lens are fixed to the hood or fixture just above the saw blade of the tabletop circular saw and the laser beam is irradiated on the square material to be cut, Even in the case of an angle or a direction, the beam proceeds in the direction of the line projected by the beam.

The present invention has the above characteristics,
When this is used for wood processing, a laser beam is applied to the cutting ink attached to it, and the saw blade is adjusted so that the line projected on the square wood matches, so that the tabletop circular saw can be attached without error The square wood can be processed on the cut black ink.

As described above, the method of combining a laser oscillator and a lot lens with a saw blade and irradiating a linear beam can use any material as the material to be cut, and can use a saw other than a circular saw. Available.

[0013]

As described above in detail, according to the present invention, even when various materials are cut, the laser beam line applied to the marking such as blackening is cut and aligned. Fine adjustment of the blade is also easy, and the work can be performed accurately and quickly, and the work efficiency is increased. Also, since there is a beam line projected at the time of work, care is taken not to place it on the tip of a saw blade such as an operator's hand or finger, so that safety is improved, and work can be easily performed by beginners as well as professionals.
