Description

  The present invention relates to a dustproof cover mainly used for a high-speed moving type machine tool, and more particularly to dustproofing in a 5-axis laser processing apparatus that is optimal for an apparatus that processes a large number of holes of different directions at high speed by a laser apparatus. Regarding the cover.

  When drilling with a machine tool, a processing tool such as a drill or a bite is usually used. However, in the processing of a workpiece made of a difficult-to-cut material, for example, Inconel material (Inconel is a trademark of Inco Corporation), if the above processing tool is used, it is difficult to perform hole processing. It is worn out and cannot be used in a single hour, and the processing efficiency is extremely low. For this reason, a laser is used for drilling such difficult-to-cut workpieces.

  On the other hand, even with laser drilling, in drilling where there are many holes to be processed and the processing directions are different, it is impossible to move the workpiece only in the X and Y axis directions. A five-axis laser processing apparatus that irradiates laser light from the Z-axis direction by an X-, Y-, C-, and A-axis movement type processing apparatus using a tilting mechanism is optimal. This device has been developed by the applicant.

In order to perform laser processing efficiently while changing the processing direction of a large number of holes, the moving speed of each part of the processing apparatus becomes extremely high. In the case of laser processing, fine dust-like chips are generated, so that it is necessary to prevent the chips from adhering to the moving surface of the moving mechanism section.
2. Description of the Related Art Conventionally, various covers are provided on a sliding surface and a rotating surface of a machine tool or the like to prevent adhesion of chips and the like. An example of this is “Patent Document 1”.
JP-A-11-125208 (FIG. 1)

  As shown in FIG. 1, the “linear actuator” of “JP-A-11-125208” of “Patent Document 1” covers the cover members (128a) and (128b) that protect the piston rods (68a) and (68b). , (130a), (130b), etc. are provided. This cover member is disposed with its inner surface in contact with the piston rods (68a) and (68b), and protects the piston rods (68a) and (68b). Resistance is generated.

  As described above, in the case of high-speed machining using laser light, the occurrence of frictional resistance becomes a major defect because each part moves at a very high speed. Therefore, a cover that does not contact the moving surface or the like and protects the moving surface or the like from dust is required.

  The present invention has been invented in view of the above circumstances, and is applied to a 5-axis laser processing apparatus to prevent dust from adhering to the moving surfaces and moving members of each part and to prevent resistance due to sliding. An object of the present invention is to provide a dustproof cover in the 5-axis laser processing apparatus. In addition, in the case of the cutting process which applies a coolant, although it is undesirable on a structure, of course, it is not limited to this.

  In order to achieve the above object, according to the present invention, the invention of claim 1 is mounted on a base table that moves in a direction (X axis and Y axis) perpendicular to each other along a horizontal plane. A support table mounted on the support table and rotating along the (C axis) around the vertical axis (Z axis), and a rising portion rotating the table in the tilt direction (A axis). A dustproof cover provided in a 5-axis laser processing apparatus having a tilting mechanism having a laser apparatus movably disposed along the Z-axis direction so as to laser process a workpiece mounted on the table; The dust-proof cover is fixed to the support base and covers the upper surface of the 5-axis laser processing apparatus, and forms a space portion that does not interfere with the tilting mechanism portion and the rotation region. Features.

  The invention according to claim 2 is the dustproof cover in the 5-axis laser processing apparatus according to claim 1, wherein the dustproof cover is formed with an inclined surface for assisting falling of the falling dustproof downward. It is characterized by.

  According to the dust-proof cover of the 5-axis laser processing apparatus of claim 1 of the present invention, the dust-proof cover is disposed so as to cover the upper part of the processing apparatus, so that the adhesion of dust to the moving part or the like is effectively prevented. At the same time, the cover other than the part that interferes with the tilting mechanism part is composed of a cover that moves together with the moving part and the like, and the generation of friction is completely prevented.

  Moreover, according to the dustproof cover in the 5-axis laser processing apparatus of claim 2 of the present invention, by forming the inclined surface, the dust can smoothly fall along the inclined surface, and the dust can be treated more efficiently. The effect is improved.

Hereinafter, embodiments of a dustproof cover in the 5-axis laser processing apparatus of the present invention will be described in detail with reference to the drawings.
1 and 2 show a schematic structure of a 5-axis laser processing apparatus 100 provided with a dustproof cover 1 of the present invention. First, the third base table 2 is placed on the base 9, and the second base table 4 is mounted so as to be movable in the Y-axis direction via the linear motor mechanism 3. A support base 6 that is movable in the X-axis direction (a direction perpendicular to the Y-axis) is provided on the second base base 4 via a linear motor mechanism 5. A tilting mechanism portion 7 formed to be movable in the C-axis and A-axis directions is disposed on the support base 6, and a laser device 8 is disposed on the upper surface so as to be movable along the Z-axis direction.

The tilting mechanism portion 7 includes left and right brackets 10 and 11 fixed to the upper surface of the support base 6, a rising portion 12 that is pivotally supported by the left and right rotation shafts (not shown), and the center of the rising portion 12. And the table 13 and the like arranged in the table. The rising portion 12 is configured to rotate in the A-axis direction by a drive unit (not shown) provided in the brackets 10 and 11, and the table 13 rotates along the C-axis around the Z-axis (vertical axis). It consists of what to do. The workpiece is mounted on the table 13.
The laser device 8 includes a laser light nozzle 8a and a laser oscillator 8b arranged in the Z-axis direction, but the detailed contents thereof are omitted.

  With the above structure, the support base 6 and the tilting mechanism section 7 move together in the X-axis and Y-axis directions, and the tilting mechanism section 7 rotates around the A-axis and the C-axis on the support base 6. It consists of something that moves (rotates). Due to the synchronous movement in the X-axis, Y-axis, C-axis, and A-axis directions, the workpiece on the table 13 can be turned in multiple directions, and the laser device 8 can perform hole machining in different directions. . Due to the laser processing by the laser device, more dust rises than the work piece, and it falls toward the lower side of the device. Therefore, if there is no dust-proof cover, dust will adhere to the linear motor mechanism parts 3, 5, etc. Therefore, there arises a problem that the lifetime of the apparatus is reduced.

The dustproof cover 1 includes a cover 1a that is fixed to the support base 6 and covers the upper surface thereof, a cover 1b that is fixed to the cover 1a and covers the encoders 18 and 18 at the left and right ends of the tilting mechanism 7, and a left cover 1a. , 1b and the right cover 1a, 1b and a cover plate 1c that forms a bottom surface, and the left and right are substantially symmetrical. The cover 1b has inclined surfaces 16 and 17 that are inclined downward.
Further, as shown in FIG. 3, the dust cover 1 is formed with a space A (14) and a space B (15) that do not interfere with the tilting mechanism 7.

  The dust-proof cover 1 has the above-described structure, has no portion that makes frictional contact with the apparatus side, eliminates the generation of frictional resistance, covers the upper surface of the apparatus substantially, and forms the inclined surfaces 16 and 17 so that dust is smoothly formed. Nothing is sent down and collected in each part of the device. In addition, there is no limitation of the material, plate thickness, etc., it is determined practically, and the structure is not limited to the above-mentioned content, and it is needless to say that the same technical category is applied. .
