Abstract

PURPOSE:To facilitate the lower limit positioning and adjustment work of a circular saw in use by having a stopper abutted on a protruded part when the circular saw is vibrated downward, and by regulating the vibration lower limit position of the circular saw at the time of using a saw blade or thin cutter. CONSTITUTION:When a material to be cut 17 is cut by a saw blade 15, a circular saw part 9 is first slid forward, and then the circular saw part 9 is vibrated downward, and notching work is continued until a stopper 10 is abutted on a protruded part 6 of a hinge 5, and the circular saw part 9 is slid backward while the notching is still continued, and after finishing the cutting of the material to be cut 17, the circular saw part is returned to the upper limit, so as to finish the cutting work. When the grooving work is carried out by the saw blade 15, the stopper 10 fitted by a screw to a stopper holder 11 is wound according to the degree of notching applied to the material to be cut 17, and the stopper 10 is lowered thereby, and is abutted on the protruded part 6 of the hinge 5, so as to regulate the vibration lower limit of the circular saw part 9, and the grooving work is thus finished by the same operation as the cutting work by the saw blade 15.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a sliding bench cutter having a plurality of lower limit position stopper devices to which a saw blade and a grooving cutter can be attached.

[Background of the invention]

The conventional lower limit position stopper device is
No. 393 and Utility Model Application No. 164390/1983.

These are lower limit position stopper devices when using a single saw blade, and there are multiple tools to be installed on the circular saw, especially when tools with a smaller diameter than the saw blade can be installed, such as a groove cutter. However, there was a problem in that it was necessary to reset the lowest swing position of the optical saw when the saw blade was used. This problem will be explained with reference to FIG. 7. Normally, the stopper 10 is threadedly fitted to the circular saw part 9, the fixation of the stopper 10 is released by the butterfly nut 14, and the stopper 10 is moved up and down. The lower limit of swing of the section 9 is set and a cut is made into the workpiece 17. Due to the high frequency of cutting work with the saw blade 15, the stopper 1
0 by tightening lock nuts 13 (two pieces) to each other, and the lock nuts 13 regulate the upper limit position of the stopper 10, that is, the lowest swing limit position of the circular saw part 9, and the saw blade 15 is fixed by tightening the lock nuts 13 (two pieces) to each other. Care is taken to prevent the saw blade 15 from coming into contact with the cutting edge groove 18. Saw blade 1
In the case of grooving work according to No. 5, loosen the cutter/socket 14, move the stopper 10 downward, and bring the stopper 10 into contact with the protruding portion 6 of the hinge 5 to regulate the lower limit position of swing of the circular saw portion 9. .

During normal cutting work, the lock nut 13 fixed to the stopper 10 can be returned to its upper limit until it comes into contact with the circular saw part 9. However, when grooving is performed using the grooving cutter 16 having a smaller diameter than the saw blade 15,
From the lowest swing position of the circular saw part 9 when the saw blade 15 is installed,
It may be necessary to swing further downward. In this case, the lock nut 13 (
2) and move the stopper 10 upward, and when reinstalling the saw blade 15 after cutting the groove, the saw blade 15 will come into contact with the blade groove 18, as described above.
It was necessary to readjust lock nut 13. As described above, each time the saw blade 15 and the groove cutter 16 are attached, there is the inconvenience that the lowest swing position of the circular saw portion 9 must be adjusted.

[Purpose of the invention]

The present invention eliminates the above-mentioned drawbacks of the prior art, and improves the lower eye position of the circular saw when using the saw blade and groove cutter in a sliding tabletop cutting machine! III! The goal is to make work easier.

[Summary of the invention]

The present invention provides a method for moving a stopper above the stopper position 1 (the upper limit position of the stopper regulated by two lock nuts) that regulates the lowest swing position of the circular saw when the saw blade is attached. , when installing a groove cutting cutter with a diameter smaller than the saw blade diameter, in order to be able to move further down than the lowest swing position of the circular saw when the saw blade is installed, it is necessary to We focused on the point that it would be possible if we could change the position of the saw blade or groove cutter by making the protruding part of the hinge that comes into contact with the stopper into a multi-step shape, and by moving the stopper or the protruding part, the swinging when the saw blade or grooving cutter is attached. The relationship between the circular saw part, the saw blade, the groove cutter, the stopper, and the protruding part of the hinge has been devised so that regulation can be performed independently.

[Embodiments of the invention]

Embodiments of the present invention will be described with reference to FIGS. 1 to 5.

In the figure, a workpiece 17 is supported on the upper surface of a base 1, a turntable 2 is embedded approximately in the center of the base 1 so as to be freely rotatable in the horizontal direction, and a holder 3 is held behind the turntable 2. A sliding holding member (not shown) is provided on the upper part of the holder 3, and a hinge 5 is connected to the sliding holding member via a guide bar 4 so as to be slidable back and forth, and the front end of the hinge 5 has a plurality of arcuate steps. A protrusion 6.7 is formed.

Above the hinge 5 is a base 1 with the hinge shaft 8 as a fulcrum.
A circular saw portion 9 is pivotally supported so as to be vertically swingable. A stopper holder 11 into which a stopper 10 is screw-fitted is rotatably supported on the circular saw part 9 with a shaft 12 as a fulcrum, and either a saw blade 15 or a grooving cutter 16 is rotatably supported by a mold. One side is retained. In addition, the stopper 1o can be fixed to the stopper 10 by tightening the lock nuts 13 (two pieces) together.
The upper part and the lower end of the stopper holder 11 come into contact with each other, and upward movement of the stopper 10 is inhibited. Further, by tightening a butterfly nut 14 screwed into the stopper 1o, the amount of downward movement of the stopper 10 can be set at any position.

In the above configuration, when cutting the workpiece 17 with the saw blade 15, the circular saw part 9 is first slid forward, then the circular saw part 9 is swung downward, and the stopper 10 is connected to the hinge 5. Make a cut until it comes into contact with the protruding part 6, and then slide the circular saw part 9 backward while making a further cut, and after cutting the workpiece 17, return the circular saw part to the upper limit and complete the cutting work. let

When grooving with the saw blade 15, the stopper 10 screwed into the stopper holder 11 is rotated according to the amount of cut to be made into the workpiece 17, and the stopper 10 is lowered to allow the hinge 5 to protrude. The circular saw part 9 is brought into contact with the part 6 to regulate the lower limit of swing of the circular saw part 9, and the grooving work is completed by the same operation as the cutting with the saw blade 15 described above.・Furthermore, as shown in FIG. 2, when performing grooving work using the grooving cutter 16, the stopper holder 11 is attached to the protrusion 7 because the grooving cutter 16 has a smaller diameter than the outer diameter of the normal saw blade 15. The stopper 10 is rotated to the contact position, the stopper 10 is lowered and brought into contact, and the lower limit of the swing is regulated so that a predetermined depth of cut is given to the workpiece 17, similar to the cutting with the saw blade 15 described above. The grooving work is completed by this operation.

As shown in FIGS. 6 to 8, a stopper 10 is screwed directly onto the side surface of the circular saw part 9 so as to be movable up and down, and a protrusion 6.7 is attached to the hinge 5 perpendicularly to the surface of the saw blade 15. If provided movably, the protrusion 6 can be brought into contact with the saw blade 15 when the saw blade 15 is used, and the protrusion 7 can be brought into contact with the groove cutter 16 when the groove cutter 16 is used.

〔Effect of the invention〕

According to the present invention, even when the outer diameter of a tool such as a saw blade or a grooving cutter changes, the stopper is provided at the abutting part, that is, at the hinge, to regulate the lower limit swing position of the circular saw corresponding to the specifications. By providing multiple stages of protruding parts, the protruding part that the stopper contacts can be replaced without changing the upper position IF of the stopper (the lowest swinging position M of the circular saw part) when the saw blade is attached. When installing a grooving cutter with a small tool outside diameter, the circular saw part can be lowered further than the lowest swing position of the circular saw part when the saw blade is installed, so it will not be necessary to restart the saw part again. When using this blade, it is easier to use by replacing the protruding part that the stopper contacts, improving operability.
