Description

  The present invention relates to a processing apparatus and a processing method, and more particularly to a processing apparatus including an auto tool changer mechanism that automatically changes a processing tool attached to a spindle, and a processing method in the processing apparatus.

  Conventionally, it was isolated from the outside by a processing tool such as an end mill equipped with a cutting edge at the tip of the shank based on a processing program such as NC data (NC program) having a plurality of processing steps by numerical control using a microcomputer or the like. 2. Description of the Related Art A processing apparatus is known that cuts a workpiece in a three-dimensional manner within a processing space that is a sealed space in a state, and produces a three-dimensional structure having a desired shape from the workpiece.

  In such a processing apparatus, for example, a spindle on which a shank of a processing tool is attached and a table on which a workpiece is placed are arbitrary in the X axis direction, the Y axis direction, and the Z axis direction in the XYZ orthogonal coordinate system. The relative positional relationship between the cutting edge of the processing tool and the workpiece placed on the table is arbitrarily changed in three dimensions by moving in the direction.

  Then, according to each machining step of the machining program, the workpiece is moved to the desired shape by the cutting edge of the machining tool by moving the spindle and the table while bringing the cutting edge of the machining tool rotated by the spindle into contact with the workpiece. To make a three-dimensional structure.

  Further, in such a processing apparatus, it is common to use a plurality of processing tools having cutting edges having shapes corresponding to respective uses such as roughing and finishing as processing tools. Is placed in the machining space of the machining apparatus.

  Then, the machining device returns the machining tool for roughing or finishing, which holds the base end of the shank to the spindle chuck, to the magazine and holds it from the spindle chuck under the control of the microcomputer. The machining tool selected for the spindle by removing the machining tool and selecting one of the other machining tools contained in the magazine and holding the proximal end of the shank of the selected machining tool on the spindle chuck It has a mechanism that automatically performs the process of holding the.

  Such a mechanism is a well-known technique disclosed in, for example, JP-A-9-314435, JP-A-2002-345844, or JP-A-2015-62974, and is widely used as an auto tool changer mechanism. Generally known.

  Therefore, since a conventionally known technique can be applied to such an auto tool changer mechanism, a detailed description of its configuration and operation will be omitted as appropriate.

  Here, in the processing apparatus provided with the above-described auto tool changer mechanism, when the workpiece is cut by the processing tool, the cutting powder is accumulated on the upper surface portion of the magazine disposed in the processing space. It was.

  The accumulation of cutting powder on the upper surface of the magazine or the like causes a problem when the processing tool is replaced by the auto tool changer mechanism.

  For this reason, in a processing apparatus equipped with a conventional auto tool changer mechanism, for example, a compressor serving as an air source is provided outside the processing apparatus, and compressed air generated by the compressor is supplied into the processing space via a pipe. The air blow nozzle arranged in the above was introduced, and compressed air was jetted from the air blow nozzle toward the upper surface portion of the magazine.

  The cutting powder deposited on the upper surface of the magazine is blown away by the compressed air sprayed from the air blow nozzle, and this causes problems when replacing the machining tool due to the accumulation of cutting powder on the upper surface of the magazine. Was preventing.

  However, in the above-described conventional technology, it is necessary to prepare a compressor as an air source outside the processing apparatus, and it is necessary to provide piping for sending compressed air from the compressor to the processing space. However, a pressure adjusting mechanism such as a valve for adjusting the pressure of the compressed air delivered from the compressor was also necessary.

  For this reason, it has been pointed out that the entire system becomes large and expensive.

  Further, in the above-described conventional technology, it has been pointed out that the operator needs to adjust the pressure of the compressed air delivered from the compressor, which increases the burden on the operator.

  Hereinafter, an example of an embodiment of a processing apparatus and a processing method according to the present invention will be described in detail with reference to the accompanying drawings.

  First, the overall configuration of the processing apparatus 10 will be described with reference to FIG.

  The entire operation of the processing apparatus 10 is controlled by the microcomputer 32, and the workpiece 100 is cut based on the processing program.

  The processing apparatus 10 includes a fixed base member 12, side members 14 </ b> L and 14 </ b> R which are erected at right and left ends of the base member 12 and perpendicular to the base member 12, and a base member 12 at the rear end of the base member 12. In addition to standing upright and a rear member 16 that connects the left and right side members 14L and 14R, a processing space S for cutting the workpiece 100 is formed.

  The machining space S is separable from the outside by a cover member (not shown) detachably disposed on the front side (front side), and the machining space S is a sealed space in a state of being isolated from the outside. The workpiece 100 is machined inside.

  The guide rail 18 is disposed so that both ends thereof are supported by the side members 14L and 14R and extended in the X-axis direction in the XYZ orthogonal coordinate system.

  The support member 20 is mounted on the guide rail 18 so as to be slidable along the X-axis direction, and is supported movably on the left side and the right side along the X-axis direction.

  The head 22 is mounted on the support member 20 so as to be slidable along the Z-axis direction, and is disposed so as to be movable upward and downward along the Z-axis direction.

  The head 22 has a spindle 24 that holds various processing tools 110 having a cutting edge 110b having a shape corresponding to each application such as roughing and finishing at the tip of the shank 110a so as to be rotatable around the Z axis. It is arranged. The spindle 24 is disposed so as to protrude from the lower side of the head 22 toward the lower side in the Z-axis direction.

  A pair of guide rails 26 extending in the Y-axis direction are disposed on the base member 12 in parallel.

  The table 28 is mounted on the guide rail 26 so as to be slidable along the Y-axis direction, and is slidably disposed on the front side and the rear side along the Y-axis direction. A workpiece 100 made of a resin material such as a transparent acrylic plate is placed on the upper surface 28a of the table 28, for example. The workpiece 100 is not limited to the resin material such as the transparent acrylic plate described above, and other various materials are used. The workpiece 100 may be fixed to the upper surface 28a of the table 28 using, for example, a double-sided tape.

  Note that a motor serving as a drive source for moving the support member 20 supporting the head 22 in the X-axis direction, a motor serving as a drive source for moving the head 22 supported by the support member 20 in the Z-axis direction, and the table 28 as the Y-axis. A motor that is a driving source that moves in the direction and a motor that is a driving source that rotates the machining tool 110 held on the spindle 24 around the Z axis are not shown.

  Since the spindle 24 can move in the X-axis direction and the Z-axis direction via the head 22, the machining tool 110 held by the spindle 24 and the spindle 24 moves in the Z-axis direction in the head 22 and moves the head 22. To move in the X-axis direction. In the processing apparatus 10, the positional relationship between the table 28 that moves in the Y-axis direction and the spindle 24 that moves in the X-axis direction and the Z-axis direction can be relatively changed in three dimensions.

  In the processing apparatus 10, the microcomputer 32 controls the driving of each motor described above according to each processing step of the processing program, thereby bringing the cutting edge 110 b of the processing tool 110 rotated by the motor into contact with the workpiece 100. While moving the head 22 and the table 28, the workpiece 100 is cut into a desired shape by the cutting edge 110b of the processing tool 110 to produce a three-dimensional structure.

  On the upper surface 28a of the table 28, there is disposed a magazine 30 that accommodates various processing tools 110 each having a cutting edge 110b having a shape corresponding to each use such as roughing and finishing.

  In the processing apparatus 10 according to the present embodiment, the magazine 30 is disposed in the vicinity of the side member 14L, and the processing tool 110 held by the spindle 24 can be disposed on the upper surface 30a of the magazine 30 from above. Has been.

  The processing apparatus 10 includes a conventionally known auto tool changer mechanism. The processing tool 110 holding the base end portion of the shank 110a on the chuck 24a of the spindle 24 is returned to the magazine 30, and the chuck 24a of the spindle 24 is returned. The processing tool 110 held from the processing tool 110 is removed, and one of the other processing tools 110 accommodated in the magazine 30 is selected, and the base end portion of the shank 110a of the selected processing tool is used as the chuck of the spindle 24. By holding at 24a, a process of holding the selected processing tool 110 on the spindle 24 is automatically performed.

  Here, the processing apparatus 10 includes a blower mechanism unit 200 (see FIG. 2) described later on the head 22 as compared with a processing apparatus including a conventionally known auto tool changer mechanism, and also includes the magazine 30. The difference is that a concave groove structure portion 40 (see FIG. 3), which will be described later, is provided on the upper portion, and other configurations and functions are not different from those of conventionally known processing apparatuses.

  Therefore, in the following description, the configuration and operation of the blower mechanism 200 provided in the head 22 and the concave groove structure 40 formed in the upper part of the magazine 30 will be described in detail. A description of the configuration and operation is omitted.

  A detailed configuration of the blower mechanism 200 provided in the head 22 will be described with reference to FIG.

  The head 22 includes a blower mechanism 200 that extends along the Z-axis direction in the region of the right end portion in the direction of arrow A in FIG. In FIG. 2, in order to show the internal configuration of the blower mechanism unit 200 in detail, a state in which the region part of the blower mechanism unit 200 in the front cover 22a is removed is shown.

  The air blowing mechanism unit 200 includes an air inlet 202 formed in the upper surface cover 22 b of the head 22. The air inlet 202 is formed in a slit shape so that an operator will not be injured by directly touching the electric fan 214 (described later) with a finger.

  The air blowing mechanism 202 includes a duct 206 formed to communicate with the lower side along the Z-axis direction from the air inlet 202 to the air outlet 204 formed in the lower surface cover 22c of the head 22. The duct 206 is formed such that the lower side portion 206a is bent in the vicinity of the chuck 24a of the spindle 24, for example, in a direction slightly lower in the Z-axis direction from the chuck 24a.

  More specifically, the duct 206 includes a back surface portion 208 positioned along the XZ plane, and a front surface portion (not shown in FIG. 2) positioned along the XZ plane and disposed facing the back surface portion 208. And a portion corresponding to the inner wall portion of the area portion of the blower mechanism portion 200 in the front cover 22a), a right side portion 210 (located on the right end portion side of the head 20) located along the YZ plane, and It is composed of four surfaces including a left side 212 (positioned on the left end side of the head 20) that is positioned along the YZ plane and is opposed to the right side 210. The back portion 208, the front portion, the right portion 210, and the left portion 212 are formed such that the lower portions thereof are inclined in the direction of the chuck 24a of the spindle 24 and reach the exhaust port 204. A bent lower side portion 206a of 206 is formed.

  In the vicinity of the air inlet 202 in the duct 206, an electric fan 214 is disposed as a blowing means. Therefore, when the operation of the electric fan 214 is started, the electric fan 214 sucks air from the suction port 202, exhausts the sucked air from the exhaust port 204 through the duct 206, and directs it toward the vicinity of the chuck 24a. To blow air. That is, in the processing apparatus 10, air is blown toward the vicinity of the chuck 24 a from a direction different from the axial direction of the spindle 24.

  The positional relationship between the exhaust port 204 of the duct 206 and the chuck 24a of the spindle 24 is preferably arranged so that both are substantially coaxial on the X axis.

  Further, the lower side portion 206a of the duct 206 is formed to be bent in the vicinity of the chuck 24a of the spindle 24, for example, in a direction slightly lowered in the Z-axis direction from the chuck 24a, and in the vicinity of the chuck 24a by the electric fan 214. More specifically, the duct 206 and the exhaust port 204 are moved to a predetermined position above the processing tool 110 to be replaced by the auto tool changer mechanism. Sometimes, it is preferable to design so that the air blown from the exhaust port 204 by the electric fan 214 hits the shank 110a of the processing tool 110 to be replaced.

  A detailed configuration of the magazine 30 will be described with reference to FIG.

  The magazine 30 is different from the conventional magazine in that the groove structure portion 40 is formed on the upper surface portion 30a extending in the X-axis direction where the processing tool 110 is arranged, as compared with the conventional magazine.

  The concave groove structure portion 40 includes a front plate portion 42 made of a transparent plate disposed so as to extend from the front portion 30b of the magazine 30 along the ZX plane, and the rear surface portion 30c side of the magazine 30 along the ZX plane. And a back plate portion 44 formed so as to extend. That is, the front plate portion 42, the back plate portion 44, and the upper surface portion 30a are both the bottom surface (upper surface portion 30a) of the recessed groove structure portion 40 extending in the X-axis direction and both wall surfaces (front plate portion) formed upright from the bottom surface. 42 and back plate portion 44) are formed. Therefore, the upper surface portion 30 a of the magazine 30 where the processing tool 100 is located is located in the recessed groove structure portion 40.

  Here, the height in the Z-axis direction of the front plate portion 42 and the back plate portion 44 is not particularly limited, but from the viewpoint of improving the efficiency of removal of cutting powder, for example, the following It is preferable to make it high.

  That is, as shown in FIG. 7A, when the upper surface portion 30a of the magazine 30 is configured to be provided with a stocker 50 that attracts and holds the processing tool 110 by magnetic force, the front plate portion 42 is provided. The upper end portion 42a of the back plate 44 and the upper end portion 44a of the back plate portion 44 are formed such that the height in the Z-axis direction is located above the height H in the Z-axis direction of the stocker 50 constituting the upper surface portion 30a. . Further, as shown in FIG. 7B, when the upper surface portion 30 a of the magazine 30 is configured without the stocker 50, the upper end portion 42 a of the front plate portion 42 and the upper end portion of the rear plate portion 44. The height in the Z-axis direction with respect to 44 a is formed so as to be positioned above the height H in the Z-axis direction of the upper surface portion 30 a without the stocker 50.

  In the above configuration, the operation of the machining apparatus 10 will be described. The machining apparatus 10 controls the driving of each motor described above by the microcomputer 32 based on a machining program including tool path data and the like. By driving each motor, the spindle 24 is moved to an arbitrary position in the XYZ orthogonal coordinate system, and the processing tool 110 held by the spindle 24 is rotated around the Z axis. Thereby, in the processing apparatus 10, based on the processing program corresponding to the shape of the desired three-dimensional structure to be produced, the workpiece 100 placed on the upper surface 28a of the table 28 is cut by the processing tool 110. Processing is performed. In addition, about the cutting process in the above-mentioned processing apparatus 10, since a conventionally well-known technique can be applied, the detailed description is abbreviate | omitted.

  When the machining apparatus 10 is instructed to replace the machining tool 110 held on the spindle 24 by the machining program, the machining apparatus 10 performs an exchange process of the machining tool 110 by the auto tool changer mechanism.

  Here, in the processing apparatus 10, when the processing program instructs the replacement of the processing tool 110 by the auto tool changer mechanism, the electric fan 214 is started to operate, and the replacement of the processing tool 110 is completed and the spindle 24 is moved. It is assumed that the operation of the electric fan 214 is stopped when returning to the initial position when the workpiece 100 is processed. Further, in the machining apparatus 10, when the machining tool 110 is exchanged by the auto tool changer mechanism according to the machining program, the spindle 24 moves on the concave groove structure portion 40 along the X-axis direction, and the object to be exchanged. It is assumed that the processing tool 110 is set to be exchanged near the processing tool 110.

  Here, FIGS. 4 to 6 show the flow of air blown by the electric fan 214 of the blow mechanism 200 when the processing tool 110 is replaced.

  The processing apparatus 10 relatively moves the head 22 in the direction of the magazine 30 so that the spindle 24 faces the processing tool 110 to be replaced in the concave groove structure portion 40. Then, when the spindle 24 is positioned on the processing tool 110 to be replaced in the concave groove structure portion 40, the electric fan 214 of the blower mechanism portion 200 causes the inside of the concave groove structure portion 40 to extend along the extending direction of the concave groove structure portion 40. The wind is blown to blow the cutting powder accumulated on the upper surface 30a of the magazine 30 or the shank 110a of the processing tool 110 disposed on the upper surface 30a of the magazine 30.

  At this time, since the upper surface portion 30a of the magazine 30 constituting the concave groove structure portion 40 is surrounded by the front plate portion 42 and the rear plate portion 44, the wind blown from the blower mechanism portion 200 is the front plate portion 42. The back plate 44 receives the air blown from the blower mechanism 200 and is efficiently supplied into the recessed groove structure 40. As a result, cutting powder accumulated on the upper surface portion 30a of the magazine 30 and the shank 110a of the processing tool 110 disposed on the upper surface portion 30a of the magazine 30 is removed, and the processing tool 110 is replaced by the auto tool changer mechanism. Occurrence of defects due to cutting powder can be prevented.

  Further, in the processing apparatus 10 described above, since the spindle 24 moves along the X-axis direction on the concave groove structure portion 40, it is disposed on the upper surface portion 30a of the magazine 30 or the upper surface portion 30a of the magazine 30 for each replacement process. Further, the cutting powder accumulated on the shank 110a of the processing tool 110 is blown off, and the accumulation of cutting powder near the processing tool 110 other than the replacement target can also be suppressed.

  As described above, according to the processing apparatus 10, the air blower simply composed of the electric fan 214 and the duct 206 is provided in the processing apparatus 10 without providing a large facility outside the processing apparatus such as a compressor. By providing a simple structure in which the mechanism unit 200 is provided in the head 22 and the concave groove structure portion 40 including the front plate portion 42 and the back plate portion 44 is provided in the magazine 30, the upper surface portion 30 a of the magazine 30 accommodating the processing tool 110 is provided. The accumulated cutting powder can be efficiently removed.

  For this reason, the size of the entire system in the processing apparatus 10 is not increased, and the price is not increased.

  Further, according to the processing apparatus 10, since the generation of the air blow from the blow mechanism 200 and the control of the strength of the air blow are performed by the processing program that controls the processing apparatus 10, the processing tool 110 is used. There is no burden on the operator for removing the cutting powder accumulated on the upper surface portion 30a of the magazine 30 to be accommodated.

  Furthermore, according to the processing apparatus 10, since compressed air is not introduced from the outside into the processing space S, it is possible to prevent the cutting powder from leaking out of the processing space S. For this reason, in the processing apparatus 10 described above, a case has been described in which a cover member (not shown) that is detachably disposed to seal the processing space S is provided. For the purpose of only preventing leakage, it is not necessary to provide a cover member that seals the machining space S.

  The embodiment described above may be modified as shown in the following (1) to (6).

  (1) In the above-described embodiment, when the replacement of the processing tool 110 by the auto tool changer mechanism is instructed, the operation of the electric fan 214 is started, the replacement of the processing tool 110 is completed, and the spindle 24 is processed. When the electric fan 214 is returned to the initial position when the workpiece 100 is processed, the operation of the electric fan 214 is stopped, but it goes without saying that the operation start and stop timing of the electric fan 214 is not limited to this.

  That is, the position of the spindle 24 is detected, and the electric fan 214 is operated only when the spindle 24 is positioned on the concave groove structure portion 40, and the cutting powder existing in the concave groove structure portion 40 is blown by the electric fan 214. You may make it blow off.

  Alternatively, the electric fan 214 is operated only when the spindle 24 is moved to a predetermined position above the processing tool 110 to be held by the chuck 24a by the auto tool changer mechanism in the concave groove structure portion 40. The cutting powder existing in the concave groove structure portion 40 is blown off by the air blow by 214, and the operation of the electric fan 214 may be stopped when the spindle 24 moves from a predetermined position above.

  Furthermore, in synchronization with the start and stop of the operation of the processing apparatus 10, the electric fan 214 starts operating when the operation of the processing apparatus 10 is started, and the electric fan 214 also operates when the operation of the processing apparatus 10 is stopped. May be stopped.

  In short, the start and stop of the operation of the electric fan 214 may be appropriately set according to design conditions such as the processing apparatus 10 and the processing program.

  (2) In the above-described embodiment, when the machining tool 110 is replaced by the auto tool changer mechanism, the spindle 24 moves along the X-axis direction on the concave groove structure portion 40 while the machining tool 110 is moved. Although the replacement process is performed, it is needless to say that the present invention is not limited to this.

  That is, when the machining tool 110 is exchanged by the auto tool changer mechanism, the spindle 24 moves from the Y axis direction and approaches the machining tool 110 to be exchanged arranged in the concave groove structure 40. In this manner, the processing tool 110 may be replaced.

  (3) In the above-described embodiment, the air blowing mechanism unit 200 is provided in the region of the right end portion of the head 22. However, the place where the air blowing mechanism unit 200 is disposed in the head 22 is not limited thereto. Of course.

  In other words, the air blowing mechanism 200 may be provided in the region of the left end portion of the head 22. At this time, the inclination direction of the bent lower side portion 206a of the duct 206 in the blowing mechanism 200 is such that the lower side of the duct 206 in the blowing mechanism portion 200 provided in the region of the right end portion of the head 22 is bent. The inclination direction of the portion 206 a is mirror-arranged with respect to the spindle 24. That is, even when the blower mechanism 200 is provided in the region of the left end portion of the head 22, the lower side portion 206a of the duct 206 is formed to bend toward the chuck 24a of the spindle 24. .

  In addition, if the place where the air blowing mechanism 200 is disposed in the head 22 is not a region of the left end or the right end of the head 22 as described above, and is a place where the spindle 24 does not get in the way, the design conditions, etc. Depending on the situation, it may be arranged at an appropriate place.

  (4) In the above-described embodiment, the head 22 is provided with only one blowing mechanism 200. However, the head 22 may be provided with a plurality of two or more blowing mechanisms 200.

  (5) In the above-described embodiment, the lower side portion 206a of the duct 206 of the air blowing mechanism portion 200 is formed by bending toward the chuck 24a of the spindle 24, and the air blown from the air blowing mechanism portion 200 is formed. Although the direction is directed to the chuck 24a of the spindle 24, the present invention is not limited to this.

  That is, the duct 206 may be formed in a straight line without bending the lower side portion 206a of the duct 206 of the blower mechanism portion 200. In this case, since the air is not blown toward the chuck 24a of the spindle 24 from the blower mechanism unit 200, the blower position from the blower mechanism unit 200 is the replacement target before the machining tool 110 is replaced by the auto tool changer mechanism. After the head 22 is moved so as to be directed to the processing tool 110 and the cutting powder is blown away, the replacement work of the processing tool 110 is performed.

  (6) You may make it combine suitably the embodiment shown above and the modification shown in said (1) thru | or (5).

  The present invention is suitable for use in a processing apparatus that cuts a workpiece with a processing tool for cutting.
