The present invention relates to a multipurpose cutter table, and more particularly, to a multipurpose cutter table in which legs and materials supporting the table can be placed on a shelf and the shelf can be freely folded or unfolded.
In general, a wood cutting device is a device for cutting wood using a circular saw rotated by power. When wood or plywood is pushed into the rotating circular saw, it can be cut to a desired length and size as needed. That is, the cutting device for cutting wood or plywood to a desired size refers to a machine tool capable of cutting a workpiece while a circular saw is usually rotated.
This conventional wood cutting device is supported by a plurality of support parts configured in the lower portion and is configured to include a workbench having a slit hole and a rotating circular saw a portion of which is protruded toward the upper portion of the slit hole of the workbench. The wood, such as lumber or plywood, passing through the workbench is cut by the portion of the circular saw protruding from the upper portion of the slit hole.
In addition, since it is difficult to carry a bulky workbench and cannot be used at a work site, a portable cutter that can be easily carried by a worker is being used. This portable cutting machine is configured with a handle that can be gripped by a worker on one side of the circular saw, and it can cut wood by pressing the handle and lowering the circular saw in a state where the wood is close to the lower portion of the circular saw.
These conventional wood cutting devices do not have much difficulty in cutting wood vertically. However, if a cutting angle of wood is inclined instead of a vertical direction, a workbench is needed to be installed in an inclined direction, or a separate cutting device capable of inclined cutting is needed.
In order to cut a processing object such as wood at an arbitrary angle, a multifunctional cutting machine is known, which includes a body having a base with a fence on which a workpiece is placed and a turn table that is rotatable to the base; and a cutting portion supported by the turn table and having a saw blade rotating according to a motor.
In order to set the saw blade to an arbitrary cutting angle of this multifunctional cutting machine, the first step is to rotate a car steering wheel installed in the front of the turntable with respect to the base to move the turntable to a desired angle position.
Then, by rotating the car steering wheel to a fixed position, so that the front end of a shaft connected to one end thereof is in contact with the base. Since the turntable is fixed with respect to the base, unexpected movement of the turntable is prevented.
However, if the car steering wheel is excessively tightened to ensure the turntable to be fixed to the base, the shaft excessively hits the base, thereby leading to deformation or damage of the base.
For example, the following Patent Document 1 discloses ‘Wood Cutting Device Capable of Adjusting Cutting Angle.’
The wood cutting device capable of adjusting a cutting angle according to the following Patent Document 1 is configured to comprise: a base frame supported by a support frame configured on the lower portion and having a saw blade guide groove recessed along the inner surface in a horizontal direction; a support bracket configured on the top surface of the base frame in a vertical direction; two horizontal support rods each extended from one side toward the horizontal direction of the base frame; a moving bracket that is axially installed on the two horizontal support rods and moves in a left or right direction on the two horizontal support rods; a circular saw bracket coupled to the front surface of the moving bracket; and a circular saw having a rotating shaft that is axially installed and fixed to the circular saw bracket formed at the upper portion and positioned on the saw blade guide groove of the base frame.

Next, a method of operating the multipurpose cutter table according to a preferred embodiment of the present invention will be described with reference to
As shown in
In addition, when the length of a cutting object is long, the side supporting members 300 respectively installed on both sides of the table member 100 are drawn outwardly. Accordingly, the cutting object longer than the length of the table member 100 can be stably placed on the table member 100.
Furthermore, since the vertical moving frame 330 of the side supporting member 300 is installed to be adjustable in height on the horizontal moving frame 320, the height of the horizontal fixed frame 340 can be freely adjusted according to the cutting object.
The upper surface supporting member 400 enables the cutting object to be stably placed thereon. Accordingly, it is possible to put the cutting object before and after cutting during the cutting operation.
Therefore, an additional workspace can be obtained other than the table member 100.
Meanwhile, since the leg member 200 and the upper surface supporting member 400 can be folded or unfolded with respect to the fixed frame 240 and the hinge member 430, the cutter table can be stored easily when not in use.
In addition, since the side supporting member 300 can be pushed toward a center of the table member 100, the cutter table can be further easily stored.
Although the invention made by the present inventor has been described in detail according to the above embodiments, the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the gist of the present invention.
