Description

  The present invention relates to a dust collection adapter in an engraving apparatus, and more particularly to a dust collection adapter in an engraving apparatus that can be attached adjacent to a cutting tool such as a cutter for cutting an object to be engraved.

  Conventionally, a microcomputer, a cutting tool such as a cutter having a blade for cutting an object to be engraved such as a thermoplastic resin material or a light metal material, and the above-described cutting tool by the above-described microcomputer control And a driving device such as a motor that can move in a three-dimensional direction relative to the movement of the cutting tool by using the driving device under the control of a microcomputer according to a predetermined program. An engraving apparatus that can engrave an arbitrary character or figure on an object to be engraved is known.

  More specifically, in the engraving apparatus described above, a cutting tool such as a cutter is appropriately referred to as a cutting tool mounting member (hereinafter, “spindle head”) held by a tool head that is movably disposed by a driving device. ) It is supported inside via a bearing.

  When the object to be engraved is cut by a cutting tool such as this cutter, a cutting piece is generated from the cut object to be engraved. In order to collect such a cutting piece, a spindle having a cutting tool is used. In the vicinity of the cutting tool blade portion on the outer peripheral surface of the head, a dust collecting adapter is attached adjacently.

By the way, the conventional dust collection adapter has a substantially ring-like shape as a whole, and a suction port connected to a suction device is provided on a side surface thereof.

  To attach such a conventional dust collection adapter to the spindle head, first fit the dust collection adapter into the lower end of the spindle head that supports the cutting tool from directly below the spindle head, and screw it onto the lower end of the spindle head. It was fixed.

  That is, the conventional dust collecting adapter is generally ring-shaped, and thus cannot be attached from the side face direction of the spindle head, but can be attached only from directly below the spindle head.

However, when installing such a dust collecting adapter, the gap between the cutting tool blade located at the lower end of the spindle head and the work table or the object to be engraved on the work table was negligible. In this case, there is a problem in that it is difficult to fit the dust collection adapter into the gap, and it is difficult to fit the dust collection adapter into the spindle head from directly below the spindle head.

  More specifically, for example, the user needs to determine the cutting depth with the surface of the object to be engraved as a reference plane. In this case, first, the object to be engraved is placed on the work table, and the spindle The length of the blade of a cutting tool such as a cutter protruding from the lower end of the head is adjusted using a micrometer dial arranged on the spindle head, and the amount of protrusion of the blade of the cutting tool is set.

  However, if the dust collection adapter is attached after setting the projection amount of the blade part of the cutting tool in this way, it may be difficult to attach the dust collection adapter due to the positional relationship between the spindle head and the object to be engraved. .

  Contrary to the above case, when setting the protruding amount of the cutting tool blade after attaching the dust collecting adapter to the spindle head, make sure that the dust collecting adapter covers a part of the micrometer dial. Therefore, it is difficult to turn the micrometer dial, and it may be difficult to set the protruding amount of the cutting tool blade.

  Therefore, according to the conventional dust collecting adapter, because of the difficulty in installing the dust collecting adapter as described above, the user inserts the cutting tool blade protruding from the lower part of the spindle head in order to install the dust collecting adapter. It is necessary to make fine adjustments while taking into account the protruding amount of the part and the height of the object to be engraved, which makes it difficult to install the dust collection adapter, such as having to remove the dust collection adapter and then remove it again.

  Then, the engaging portion 40a-1 and the engaging portion 40b-1 are pressed against each other by the urging force of the winding spring 44 to form and hold a substantially circumferential shape. Can be easily attached to 30 without falling off.

  Further, a suction hose 46 is attached to the suction port 40ba of the dust collecting adapter 40, and the other end of the suction hose 46 is connected to the suction device.

  Finally, processing conditions such as the rotational speed and moving speed of the cutter 32 are set appropriately, and then cutting is started.

During the cutting of the object to be engraved 50 by the engraving apparatus 10, the object to be engraved 50 is cut by the rotation of the blade portion 32 a of the cutter 32, and a cutting piece is generated from the object to be engraved 50. By operating, the cutting piece is sucked through the gap between the spindle head 30 and the dust collecting adapter 40 and sucked into the suction device through the suction port 40ba.

As described above, since the dust collection adapter 40 in the engraving apparatus according to the present invention has a clip configuration different from that of the conventional ring-shaped body, the position of the spindle head 30 in the height direction is any position. Can also be attached.

  For this reason, it is of course possible to mount the spindle head 30 from directly below as in the case of the conventional dust collecting adapter. For example, the blade 32a of the cutter 32 below the spindle head 30 and the object to be engraved 50 Even when it is impossible to mount from directly below, such as when it is in contact, it can be mounted from the side of the spindle head 30, so it is easy even in situations where it is impossible to mount with a conventional dust collecting adapter Can be attached to.

Further, since the dust collecting adapter 40 is fixed not by a screw but by the biasing force of the winding spring 44, the user can easily attach or remove the dust collecting adapter 40 to or from the spindle head 30. Is possible.

Further, the spindle head 30 is constantly moving during cutting, but the dust collecting adapter 40 of the engraving apparatus according to the present invention has two rotation stoppers 40aa and 40bb. Even if a force that rotates the spindle head 30 about the axis acts on the adapter 40, the rotation stoppers 40aa and 40bb collide with the protrusions 26 of the spindle head 30. It does not rotate around the axis center.

  Accordingly, fluctuations in the position of the suction hose 46 connected to the dust collecting adapter 40 are suppressed, so that troubles such as the suction hose 46 being caught between the spindle holder 22 and the head portion 20 during operation of the engraving apparatus 10 can be avoided. It will be possible to avoid.

The embodiment described above can be modified as shown in the following (1) to (5).
