Abstract

PROBLEM TO BE SOLVED: To quickly determine a cutting position by providing a guide plate of a regular size stopper with a mechanism capable of reversing on a support shaft. SOLUTION: This auxiliary cutting tool is mounted on a high-speed cutter, a regular size stopper is fixed by a positioning knob 4 on an arbitrary position of a slide rail graduated by the measuring of the regular size stopper, a material to be cut is pressed to a guide plate 1, and fastened by a stock vice of the high-speed cutter, then the guide plate 1 is reversed, and the material is cut by switching-on of the cutter. When the reversing of the guide plate 1 is forgotten, the cutting operation is not started even though the cutter is switched on, and a matter to be cut is held between the gudie plate 1 and a cutting grinder, which prevents the scattering of the material. By using the guide plate 1, the dispersion in dimension of the cutted matters can be prevented, which dispenses with the measurement in every cutting, the cutter is switched off by returning a reversing lever 2 after the cutting, and the next measurement can be easily executed. The auxiliary cutting tool can be efficiently used when the material is cut into many pieces of the same dimension, and the cutting size can be easily changed.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conventional high-speed cutting machine equipped with a cutting aid to improve cutting accuracy and work efficiency and prevent harm.

[0001]

2. Description of the Related Art General-purpose high-speed cutting machines are often used in factories and on-site workplaces, but are generally used to measure the size of a cutting material using a measure, a writing brush, a sword, etc. However, the cutting position is determined by eye measurement, but it causes irregularities in both dimensioning and cutting, and the dimensioning must be repeated for each cutting. When many cuttings are performed, the work efficiency is poor.

[0002] In order to save dimensions for each cut, a tape measure or straight measure attached to an H-section steel or the like is set in a high-speed cutting machine. There is also a cutting work that is fixed and made into a guide plate. But,
When the object to be cut is short, thin, soft, etc., the object to be cut sandwiched between the guide plate and the high-speed rotating cutting wheel is
They lose their escape and get caught up in the rotation of the cutting wheel after cutting, causing them to scatter and damage the cutting wheel. Attachment and removal of the fixed guide plate every time it is cut is effective when the number of cuts is small. However, if the guide plate is forgotten to be removed, the above situation will occur.

[0003]

Various dedicated cutting machines have been developed to cut materials of various shapes. However, there are restrictions on the shapes and materials of the cut materials, and the machinery and equipment are large and expensive. Or it is inconvenient to carry on site work.

[0004] High-speed cutting machines are widely used in industry, regardless of the shape or material of the cutting material, because they are easy to carry and operate and are inexpensive. A cutting aid with a simple mechanism aimed at improving the cutting accuracy and working performance of this cutting machine and preventing harm.

[0005]

SUMMARY OF THE INVENTION A cutting aid is attached to a conventional high-speed cutting machine in the direction of the rotation axis by a fixed-size stopper inserted in a slide rail. The fixed-size stopper has a mechanism in which a movable guide plate is inverted around a support shaft.

A high-speed cutting machine incorporates a cutting machine switch, an electromagnetic switch, a female side of a switching plug, and a limit switch (1), and a fixed-size stopper incorporates a male side of the switching plug and a limit switch (2). Control of turning on and off.

According to the present invention, by inverting the movable guide plate of the fixed-size stopper and operating the limit switch (2), the high-speed cutting machine can be started, and the object to be cut is placed between the guide plate and the cutting wheel. Prevent it from being caught and scattered.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, a cutting aid is attached to a high-speed cutting machine, and a fixed-size stopper is fixed with a positioning knob on an arbitrary position of a slide rail whose dimensions are cut by taking the dimensions of the fixed-size stopper. Then, the material to be cut is pressed against the guide plate and tightened by a vise of a high-speed cutting machine. Then, the guide plate is turned over, and the cutting machine is turned on and cut.

If the guide plate is not turned over, the cutting machine does not start even if the switch is turned on, so that the object to be cut is caught between the guide plate and the cutting wheel and is prevented from being scattered.

[0010] Since the guide plate is used, there is no variation in the dimensions of the cut object, and it is not necessary to take the dimensions for each cut. By returning the reversing lever after cutting, the cutting machine switch is turned off, and the next dimensions can be easily taken. It is efficient when cutting a large number of the same dimensions, and the cutting dimensions can be easily changed.

This cutting aid can be easily attached and detached, and the cutting operation can be performed only by the high-speed cutting machine itself.
After that, to perform cutting using the cutting aid, attach the slide rail and turn on the cutting machine switch to enable cutting even if the guide plate is not turned over. Happens.

In order to solve the above-mentioned problem, an interlock circuit is provided in order to avoid a mistake due to a difference in procedure between the case of using only a high-speed cutting machine main body and the case of using a cutting aid. The limit switch (1) is incorporated in the main body of the high-speed cutting machine, and when the slide rail is mounted, it is operated to prohibit the cutting work, and the cutting prohibition is released when the switching plug of the fixed size stopper is set. .

In the actual cutting operation, it is rare to invert the guide plate or forget to set the switching plug. Therefore, an interlock circuit is provided, and starting of the high-speed cutting machine is prohibited.

In the embodiment, the slide rail is 1000 mm
And two sets for cutting up to 1500 mm were manufactured, and the shortest cutting length was 10 mm.

[0015]

According to the present invention, since the cutting dimensions are determined using the guide plate, the dimensions are simple, there is no variation in the dimensions of the material to be cut, and fine adjustment to the left and right is required for positioning a long and heavy material to be cut. The positioning of cutting can be done quickly just by pressing against the guide plate.

Conventionally, the cutting position is determined by measuring the size using a measure, a stone brush, a sword, etc., but by using this cutting aid, cutting accuracy and working efficiency can be reduced.
Improved.

[0017] This cutting aid can be attached and detached, facilitating storage of a high-speed cutting machine and portability for on-site work, improving cutting work at a construction site, etc. Up to a high-speed cutting machine, it can be manufactured and installed relatively easily, so the range of use is wide.

When the guide plate is turned over or the slide rail is mounted, the switch of the cutting machine will not be turned on unless the changeover plug is set. Therefore, between the cutting wheel that rotates at a high speed and the guide plate,
Workpieces are prevented from being harmed due to human error, because the cut object is pinched and scattered and damage to the cutting wheel is prevented.
