Description

  The present invention relates to a slide type cutting machine that linearly moves a cutting portion in parallel to a base.

  2. Description of the Related Art Conventionally, a cutting machine that cuts wood by rotating a blade such as a circular saw blade is known. Some of these include a slide mechanism that slides a blade parallel to a base on which wood or the like is placed so that even wood having a long cutting length can be cut.

  The slide-type cutting machine described in Patent Document 1 has a first link in which one end is connected to a cutting portion having a cutter, the other end is connected to a movable portion, one end is a first link, and the other end is a straight line. Linking means comprising second links respectively connected to the guide devices is provided.

  The sliding-type cutting machine described in Patent Document 1 configured as described above is a linear guide device including a movable unit that moves in one direction a cutting unit including a cutter in a direction orthogonal to the one direction. Therefore, the guide device is prevented from projecting in the moving direction of the blade and is suitable for work in a narrow place.

  The sliding-type cutting machine described in Patent Document 2 includes a support member provided to be tiltable with respect to the base portion, a shaft inserted through the base portion and the support member, and a hole formed in the shaft.

  However, according to the configuration of the above-described conventional slide-type cutting machine, the slide-type cutting machine described in Patent Document 1 has a linear guide device and linkage means located behind the blade, so that the cutting portion is When the linear guide device is close to the linear guide device, the linear guide device protrudes upward and overlaps, so that it is difficult to dispose the dust collecting device. Moreover, since the sliding-type cutting machine of patent document 1 has fixed the inclination angle of a cutting part, it cannot tilt a cutter with respect to the mounting surface which mounts a workpiece, A workpiece There is a problem in that it cannot be cut at a desired angle. Further, in the slide type cutting machine described in Patent Document 2, since the shape of the support member on which the tilt position adjusting mechanism and the tilt stopper are formed is substantially circular, and the installation space for the tilt mechanism is required, the slide type cutting machine is required. There was a problem that the cutting machine could not be miniaturized.

  Therefore, the present invention has been made in view of the above problems, and can efficiently collect dust generated by processing a workpiece, and the dust collector can be used in a straight line in a sliding operation of a cutting unit. It is a main object to provide a slide type cutting machine that is arranged so as not to interfere with the guide device and the linking means and can cut a workpiece at a desired cutting angle without increasing the size of the slide type cutting machine. .

If the linear guide device 3 and the linking means 5 are arranged so as to be offset in the vertical direction from the plane including the blade surface 41e in this way, the slide-type cutting machine 1 can be reduced in size, and almost the same as the plane including the blade surface 41e. The dust collection bag attached to the open end of the dust collection tube 44 moves the straight line guide without linearly intersecting the central axis of the dust collection tube 44 and the linear guide device 3 or the linking means 5 on the same plane. The cutting part 4 can be moved smoothly without hindering the operation of the device 3 and the linking means 5. Further, the dust collecting tube 44 is provided on the rear side surface of the blade portion 41 and offset to a position where it does not interfere with the linking means 5 and the holding portion 42, so that the sliding cutter can be reduced in size particularly in the front-rear direction. Can be achieved. In the present embodiment, the linear guide device 3 and the linking means 5 are arranged with an offset β in the vertical direction from the plane including the blade surface 41e, which is the surface on which the blade 41a rotates, Either one of the linking means 5 may be arranged so as to be offset in the vertical direction from a plane including the blade surface 41e that is a surface on which the blade 41a rotates.

  The present application is not limited to the above embodiment, and can be implemented in various forms. In the present embodiment, the example in which the auxiliary link is provided below the first link has been described. The link may be provided above the first link. Moreover, although the fixing of the holding portion has been described with respect to the example in which the holding portion and the first slide holder are locked, the slide shaft and the first slide holder may be fixed. Furthermore, you may comprise so that the rapid movement of a cutting part may be prevented because the link which comprises the connection means 5 is provided with a damper function.
