Japanese Patent Laid-Open No. 11-170214

  In the conventional tabletop cutting machine, when the processing member is rotated at a desired angle on the upper surface of the base portion with respect to the side surface of the circular saw blade to cut the processing member, the turntable is rotated. This rotation was performed. For this reason, together with the turntable, the holder and the cutting part supported by the holder and having a circular saw blade are rotated together, and the operator who performs the cutting work of the processing member can rotate the turntable and the cutting part. Accordingly, it has been necessary to move to the position of the substantially virtual extension surface of the side surface of the circular saw blade after rotation.

  Moreover, since it was necessary to make it the structure which rotates a holder and the cutting part which is supported by the holder and has a circular saw blade together with a turntable, there are many parts that rotate integrally, and the structure of a tabletop cutting machine Was complicated.

  Therefore, an object of the present invention is to provide a tabletop cutting machine in which the operator does not have to change the work position and the configuration of the tabletop cutting machine is simple.

In order to achieve the above object, the present invention provides a base portion on which a processing member is placed, a cutting portion that rotatably supports a cutting blade, and a rear portion of the base portion. A holder that is supported so as to be swingable in the direction of approaching and separating from the upper surface of the part, and one base side and the other side face of the cutting blade are erected on the base part, A fence having a moving shaft, supported on the base portion so as to be rotatable along the upper surface of the base portion around the rotation shaft, and capable of supporting a side surface of the processing member; and the fence and the base portion And a positioning mechanism that can position a rotation angle of the fence at a desired angle, the base portion includes a base and a turntable, and the turntable is supported on the base.

The rotation angle of the processing member with respect to the side surface of the cutting blade can be changed. For this reason, the side of the cutting part can be configured to swing in a direction approaching and separating from the upper surface of the base part on a predetermined virtual plane, and an operator who operates by operating the tabletop cutting machine The cutting work of the workpiece can be performed without changing the work position.

Compared with the conventional tabletop cutting machine in which the base part has a base and a turntable and the cutting part rotates integrally with the turntable, the rotating part can be only a fence, It is not necessary to provide the base part, and it is not necessary to have a structure in which the cutting part can be rotated integrally with the turntable, and the structure of the tabletop cutting machine can be simplified. The base portion includes a base and a turntable. The turntable is supported on the base and supports the processing member together with the base. The turntable is rotatable with respect to the base, and the fence is rotatable with respect to the base. Therefore, by using both the turning of the turntable and the turning of the fence, the range of the rotatable angle of the processing member with respect to the side surface of the cutting blade can be widened. For example, when the maximum rotation angle of the turntable is 45 degrees and the maximum rotation angle of the fence is 30 degrees, the processing member can be rotated up to 75 degrees with respect to the side surface of the cutting blade. become able to.

  Here, the holder is preferably supported by the base portion so as to be tiltable in a direction perpendicular to the side surface of the cutting blade. Since the holder is supported by the base portion so as to be tiltable in a direction perpendicular to the side surface of the cutting blade, so-called inclined cutting can be performed in which the workpiece is cut while the cutting blade is inclined.

  The holder is supported by the base portion at one end side, and a cutting portion support portion that supports the cutting portion at the other end side so as to move the cutting portion in a direction along the side surface of the cutting blade. Is preferably provided.

  The holder is supported by the base portion at one end side, and the other end side is provided with a cutting portion support portion that supports the cutting portion so as to move the cutting portion in the direction along the side surface of the cutting blade. By moving the cutting portion in the direction along the side surface of the cutting blade, it is possible to cut the processing member having a relatively long width in the direction of the side surface of the cutting blade.

  Moreover, it is preferable that a fine adjustment mechanism for finely adjusting the rotation angle of the fence is provided between the fence and the base portion.

  Since a fine adjustment mechanism for finely adjusting the rotation angle of the fence is provided between the fence and the base portion, the rotation angle of the processing member with respect to the side surface of the cutting blade is set to a desired angle with high accuracy. Can do.
