Description

  The present invention relates to a cutting apparatus capable of performing cutting by simply tilting a base and a cutting blade in synchronization with the tilt of the workpiece when cutting a long workpiece.

A cutting device is known in which a support member serving as a fulcrum is provided under the base, the base is balanced in a seesaw shape, and when a long workpiece is placed on the base, the base is adjusted to the inclination of the workpiece. (For example, Patent Documents 1 and 2).
In addition, a frame body with a bar member in the shape of a U is attached under the base, and the attachment is pivotally supported on the right side of the base and the right side of the frame body so that the left side of the base can be moved up and down, and the base on the left side There is known a cutting device provided with a lock / release operation unit that can be fixed or released to be movable up and down (for example, Patent Document 3).
Japanese Unexamined Patent Publication No. 2000-354911 Japanese Patent Laid-Open No. 2005-224931 US Patent Application Publication No. 2003/0024364 nothing special

The techniques of Patent Documents 1 and 2 have a risk of the base moving during the cutting operation.
Moreover, the technique of patent document 3 was a troublesome apparatus which had to adjust the inclination of a base by manual operation for every cutting | disconnection.

  In view of the drawbacks of the prior art as described above, the present invention provides a cutting device that can easily adjust the tilt of the base to the tilt of the workpiece, and can easily lock and easily release the tilt of the base. The purpose is to do.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

In order to achieve the above object, the present invention is configured as follows.
<Invention of Claim 1>
The base is set from the left side of the base by a cutting device main body having a cutting blade provided on the base so as to be movable up and down , and a left hand of an operator facing the cutting device main body provided on the base. A workpiece mounting portion on which a workpiece to be cut is placed, an enclosure made of a flat plate member that surrounds the entire periphery of the base that floats and supports the base from an installation surface such as the ground or a floor, and the enclosure is housed in the enclosure The base is a part that realizes the floating of the base, and a base support part provided in the enclosure for supporting the base so as to move up and down in the form of a seesaw, and on the enclosure side that constitutes the base support part A hole penetrating to the front side of the enclosure that is a part, a hole penetrating to a rear side of the enclosure that is a part of the enclosure constituting the base support part, the enclosure and the base A lock composed of a screw, a cam lever, etc. that locks and locks the tilted state of the base and releases the linked locked state so that the base can move freely up and down and up and down in the right and left directions · together comprising a release operation portion, the position of the base support part, in the state where the releasing the lock releasing operation portion, wherein the base is a right inclined edge point is a right hand side of naturally worker It is the cutting device characterized.

As is clear from the above description, the present invention has the following effects.
<Effect of the Invention of Claim 1>
A base, a cutting device main body having a cutting blade provided on the base so as to be movable up and down, a workpiece mounting portion on which the workpiece to be cut provided on the base is placed, and the base such as a ground or a floor An enclosure made of a flat plate member that surrounds the entire periphery of the base that is floated and supported from the installation surface, and a part that realizes the floating of the base that is housed in the enclosure, and the base is horizontally moved in a seesaw form A base support portion provided in the enclosure to be supported so as to move up and down, a hole penetrating to the front side of the enclosure, which is a portion of the enclosure constituting the base support portion, and the base support portion A hole penetrating to the rear side of the enclosure, which is a part on the enclosure side, and connecting and fixing the enclosure and the base to lock the tilted state of the base and release the connection locked state The A cutting device comprising: a lock / release operation unit made up of a screw, a cam lever, etc., which can freely move left and right up and down and up and down in the seesaw form of the source. Because there is
(1) To adjust the tilt of the base with the workpiece placed on the base, the base of the workpiece and the base surface can be easily adjusted by simply pressing the workpiece against the base with the lock / release operation part released. It is possible to adjust the tilt of the base quickly and accurately, and to lock the base easily and quickly by operating the lock / release operation part in a locked state so that the cutting operation can be performed safely. There is an effect.
(2) Since the base is surrounded by the enclosure, the enclosure forms an integrated landscape with the base to realize a form without any sense of incongruity, and has the effect of reducing the lifting from the installation surface of the base. .
(3) When moving, placing, etc., the lock / release operation part is locked (always locked except during tilt adjustment), so that the enclosure can be moved and placed without shaking. There is an effect.
(4) The load of the workpiece positioned on the left side is more easily applied to the base than when the right side is raised, and it is easy to tilt quickly and the operability is good.

  Hereinafter, the present invention will be described in detail with reference to the best mode for carrying out the invention shown in the drawings.

  In the first preferred embodiment for carrying out the present invention shown in FIGS. 1 to 5, reference numeral 1 denotes a cutting device. The cutting device 1 is provided on the base 2 and the base 2 so as to be movable up and down. A cutting device main body 4 having a cutting blade 3 formed thereon, a workpiece mounting portion 6 on which a workpiece 5 to be cut provided on the base 2 is placed, and the base 2 is lifted and supported from an installation surface such as the ground or floor An enclosure 7 surrounding the periphery of the base 2, a base support portion 8 for supporting the base 2 housed in the enclosure 7 so as to move up and down in the form of a seesaw with the enclosure 7, and the enclosure 7 and the base 2 are connected and fixed to lock the tilted state of the base 2, and the lock is made up of a screw, a cam lever, etc. that allows the base 2 to move freely left and right and up and down by releasing the connected locked state. It consists of release operation part 9 There.

  The lock / release operation unit 9 includes an adjustment plate 21 made of a flat plate member that has an upper and lower adjustment hole 20 (extending to the enclosure 7) provided on the upper edge of the enclosure 7, and the adjustment plate 21.
