A work holding unit 16 that holds a work, a sensor 34 that detects opening and closing of the cover 12a of the housing 12, and a display unit that can display various images and instructions to the operator. 22.

  Note that the machining space is a space in which the workpiece is cut by the machining tool 26 in the cutting unit 14, and is substantially a front side opened by the upper surface 30a, the right side surface 30b, the left side surface 30c, the back surface 30d, and the bottom surface 30e. It is formed in a box shape.

  In addition, the processing space is closed from the external space by closing the cover 12a of the housing 12, and is opened to communicate with the external space by opening the cover 12a. Then, the cutting process is performed with the machining space closed, and the maintenance in the machining space is performed with the machining space opened.

  The entire operation of the processing apparatus 10 is controlled by the microcomputer 18. Note that, for example, a personal computer (not shown) provided separately is connected to such a microcomputer 18, and processing data representing the shape of a processed product to be produced from the personal computer by an operator is provided. Various data such as these are input to the microcomputer 18.

  More specifically, in the cutting unit 14, the main shaft 20 is fixed to a moving member (not shown) that can move in the X-axis direction and the Z-axis direction of the XYZ orthogonal coordinate system on the upper surface 30a of the processing space. It is arranged.

Shaft 20 has a holding member 20-2 for holding a machining tool 26 in the housing 20-1, a pulley 20-3 provided at the upper portion of the holding member 20-2, the holding member 20-2 Z axis The bearing 20-4 is rotatably supported around the bearing 20-4. Note that the lower side of the holding member 20-2 is exposed to the outside of the housing 20-1.

  A motor 24 is provided in the vicinity of the main shaft 20, and a pulley 28 is provided at the tip of a rotating shaft 24-1 of the motor 24, and between the pulley 28 and the pulley 20-3 of the main shaft 20. The belt 32 is stretched endlessly.

  Accordingly, when the pulley 28 rotates together with the rotating shaft 24-1 of the motor 24, the pulley 20-3 rotates via the belt 32.

Thereby, the holding member 20 -2 pulley 20-3 is provided on an upper end portion also becomes possible to rotate about the Z-axis, rotating at even around the Z-axis machining tool 26 held by the holding member 20-2 by the rotation Will be.

  The spindle 20 has at least the holding member 20-2 exposed to the outside of the housing 20-1 positioned in the processing space so that the processing tool 26 held by the holding member 20-2 is positioned in the processing space. Is arranged.

  Thus, the operator holds the processing tool 26 on the holding member 20-2 of the main shaft 20 in the processing space with the cover 12a opened, or holds the holding member 20-2 of the main shaft 20 in the break-in process (described later). Can be rotated manually. When the operator manually rotates the holding member 20-2, the operator rotates the holding member 20-2 by picking a part of the holding member 20-2 exposed from the housing 20-1 with a finger.

  The work holding unit 16 is provided on a moving member (not shown) that moves in the Y-axis direction of the XYZ orthogonal coordinate system, and is configured to hold the work so as to be rotatable around the X-axis.

  The sensor 34 detects opening / closing of the cover 12a, and when the cover 12a is opened, a first signal indicating that the cover 12a has been opened is output to the determination unit 64 (described later) of the microcomputer 18. At the same time, when the cover 12a is closed, a second signal indicating that the cover 12a is closed is output to a determination unit 64 (described later) of the microcomputer 18.

  The microcomputer 18 performs a process for producing a processed product based on the processed data, a break-in process performed when the microcomputer is not used for a long time, and the like.

  Here, the functional configuration of the microcomputer 18 will be described with reference to FIG.

  The microcomputer 18 operates the spindle 20 and the work holding unit 16 based on the machining data to produce a machined product, a storage unit 52 for storing various data such as machining data, and a habituation. And a break-in processing unit 54 for performing processing.

  The break-in processing unit 54 includes a movement control unit 60 for moving the main shaft 20 to a predetermined position, and an information output unit that outputs information prompting the manual rotation of the holding member 20-2 of the main shaft 20 to the display unit 22. 62, a determination unit 64 that determines whether the cover 12a is opened or closed, and a rotation control unit 66 that drives the motor 24 to control the rotation of the holding member 20-2 of the main shaft 20.

  More specifically, the movement control unit 60 drives a moving member (not shown) to move the spindle 20 to a position where the operator can easily rotate the holding member 20-2 manually in the processing space. These positions are set in advance and stored in the storage unit 52.

  Further, the information output unit 62 outputs image information and character information that prompts the holding member 20-2 of the main shaft 20 to be manually rotated to the display unit 22.

Determine the constant unit 64 makes a determination of the opening and closing of the cover 12a on the basis of the result of the detection in the sensor 34.

  That is, when the first signal indicating that the cover 12a is opened is output from the sensor 34, the determination unit 64 determines that the cover 12a has been opened, and the sensor 34 has closed the cover 12a. Is output, it is determined that the cover 12a is closed.

  When the determination unit 64 determines that the cover 12a has been opened, the rotation control unit 66 determines that the holding member 20-2 has been manually rotated by the operator, and then the determination unit 64 has closed the cover 12a. If determined, the motor 24 is driven to start the rotation of the holding member 20-2.

  Then, when the rotation of the holding member 20-2 is started, the rotation control unit 66 controls the rotation number to be increased stepwise.

  In the above configuration, when the machining apparatus 10 according to the first embodiment of the present invention performs a cutting process on a workpiece, the worker holds the workpiece in the workpiece holding unit 16 and causes the microcomputer 18 to hold the workpiece. Enter machining data.

  Thereafter, in the processing apparatus 10, when the operator instructs the start of the cutting process by an operator (not shown), first, the spindle 20 is operated and stored in the magazine portion 58 provided in the processing space. The processed tool 26 is attached to the holding member 20-2 of the main shaft 20.

Then, while rotating the machining tool 26 around the Z axis on the spindle 20, based on the inputted machining data, the work holding unit 16 is moved in the Y axis direction, and the spindle 20 is moved in the X axis direction and the Z axis direction. Moving.

  Thereby, the relative positional relationship between the work held by the work holding unit 16 and the processing tool 26 attached to the holding member 20-2 of the spindle 20 is changed in three dimensions, and the work tool 26 applies the work to the work. Cutting is performed.

  Furthermore, at this time, based on the input machining data, the work held by the work holding unit 16 is rotated around the X axis.

  As a result, cutting is performed while the work tool 26 attached to the holding member 20-2 of the main shaft 20 is brought into contact with the work held by the work holding unit 16 at a predetermined angle.

  In this manner, in the processing apparatus 10, the relative positional relationship between the workpiece and the processing tool 26 is changed in three dimensions based on the processing data under the control of the production control unit 50 in the microcomputer 18. The workpiece is cut by the machining tool 26 while adjusting the angle at which the machining tool 26 abuts against the workpiece.

  Next, a break-in process performed at a predetermined timing such as when the processing apparatus 10 according to the first embodiment of the present invention is not used for a long period of time (for example, for one month) will be described.

  First, the operator confirms that the cover 12a is closed. At this time, if the cover 12a is open, the cover 12a is closed.

  After that, when the operator performs an operation of executing a break-in process using an operator (not shown), the break-in process is started by the microcomputer 18.

  Here, the flowchart of FIG. 4 shows the detailed processing contents of the break-in processing in the machining apparatus according to the first embodiment of the present invention.

  When the break-in process shown in FIG. 4 is started, first, the spindle 20 is moved to a predetermined position set in advance (step S402).

  That is, in the process of step S402, the movement control unit 60 moves the spindle 20 to a preset position, for example, a position where an operator can easily rotate the holding member 20-2 manually.

  Next, a display that prompts the user to manually rotate the spindle 20 a predetermined number of times is displayed on the display unit 22 (step S404).

  That is, in the process of step S404, image information and character information that prompts the information output unit 62 to manually rotate the holding member 20-2 of the spindle 20 a predetermined number of times (for example, 10 times) are displayed. It outputs to the display part 22, and the display based on the said image information and the said character information is performed on the display part 22 (refer FIG. 7).

  At this time, together with the image information and character information described above, character information that prompts the user to close the cover 12a after manually rotating the holding member 20-2 may be output.

  Thereafter, it is determined whether or not the cover 12a has been opened (step S406).

  If it is determined by the determination process in step S406 that the cover 12a is not opened, the operator determines that the holding member 20-2 has not been rotated, returns to the process in step S406, and again repeats step S406. Perform the process.

  That is, in the determination process of step S406, this determination process is repeated until it is determined that the cover 12a is opened.

  When the determination process of step S406 is started, the time is counted, and when the counted time reaches a predetermined time, the cover 12a is opened from the information output unit 62 and the holding member 20 of the spindle 20 is reached. -2 is output to the display unit 22 as image information or character information for prompting manual rotation, or character information indicating that the break-in processing is to be terminated, and based on the output image information or character information. Display may be performed.

  If it is determined by the determination processing in step S406 that the cover 12a has been opened, it is determined that the holding member 20-2 has been rotated by the operator, and it is determined whether or not the cover 12a has been closed. (Step S408).

  If it is determined by the determination process in step S408 that the cover 12a is not closed, the process returns to step S408, and the process in step S408 is performed again.

  That is, in the determination process of step S408, this determination process is repeated until it is determined that the cover 12a is closed.

  When the determination process of step S408 is started, the time is counted. When the counted time reaches a predetermined time, the spindle 20 is manually rotated from the information output unit 62, and then the cover 12a. Image information or character information prompting the user to close the image, or character information indicating that the break-in processing is to be terminated is output to the display unit 22, and the display unit 22 performs display based on the output image information or character information. Also good.

  If it is determined by the determination process in step S408 that the cover 12a is closed, the spindle 20 is rotated at 12000 rpm for 10 minutes (step S410), and then the process proceeds to step S412 (described later).

That is, in the process of step S410, the rotation control unit 6 6, to rotate the holding member 20-2 of the spindle 20 at a rotational speed 12000rpm drives the motor 24.

  Further, when the rotation of the holding member 20-2 at the rotation speed of 12000 rpm is started, time counting is started.

  Thereafter, when the counted time reaches 10 minutes, the process proceeds to step S412 (described later).

  In the process of step S412, the main shaft 20 is rotated at 30000 rpm for 2 minutes, and then the process proceeds to step S414 (described later).

That is, in the processing of this step S412 is the rotation control unit 6 6 controls the motor 24, increases the rotational speed of the holding member 20-2 of the spindle 20 that rotates at a rotational speed 12000rpm to 30000 rpm.

  Further, when the rotation speed of the holding member 20-2 is increased to 30000 rpm, time counting is newly started.

  After that, when the counted time reaches 2 minutes, the process proceeds to step S414 (described later).

  In the process of step S414, the spindle 20 is rotated at 48000 rpm for 2 minutes, and then the process proceeds to a process of step S416 (described later).

That is, in the processing of this step S414 is the rotation control unit 6 6 controls the motor 24, increases the rotational speed of the holding member 20-2 of the spindle 20 that rotates at a rotational speed 30000rpm to 48000rpm.

  Further, when the rotation speed of the holding member 20-2 is increased to 48000 rpm, time counting is newly started.

  After that, when the counted time reaches 2 minutes, the process proceeds to step S416 (described later).

  In the process of step S416, the spindle 20 is rotated at 60000 rpm for 5 minutes, and then the break-in process is terminated.

That is, in the processing of this step S416 is the rotation control unit 6 6 controls the motor 24, increases the rotational speed of the holding member 20-2 of the spindle 20 that rotates at a rotational speed 48000rpm to 60000 rpm.

  Further, when the rotation speed of the holding member 20-2 is increased to 60000 rpm, time counting is newly started.

  Thereafter, when the counted time reaches 5 minutes, the break-in processing is terminated.

  As described above, when performing the break-in process, the machining apparatus 10 according to the first embodiment of the present invention first rotates the holding member 20-2 of the spindle 20 with respect to the operator. When the cover 12a is closed after the cover 12a is opened, it is determined that the operator manually rotates the holding member 20-2 of the main shaft 20, and then the number of rotations of the holding member 20-2 of the main shaft 20 is determined. A break-in operation that rotates while raising the speed stepwise was performed.

  As a result, in the machining apparatus 10 according to the first embodiment of the present invention, even if the grease in the bearing 20-4 is hardened, the spindle 24 is manually rotated by the operator, so the motor 24 Therefore, an excessive current does not flow through.

  For this reason, according to the processing apparatus 10 according to the first embodiment of the present invention, an unnecessary load is not applied to the motor 24 in the break-in process.

  Next, a second embodiment of the processing apparatus according to the present invention will be described with reference to FIG.

  FIG. 5 is an explanatory diagram showing the configuration in the vicinity of the main shaft in the machining apparatus according to the second embodiment of the present invention.

  The processing apparatus according to the second embodiment of the present invention having the configuration shown in FIG. 5 is different from the above-described processing apparatus 10 according to the first embodiment of the present invention in the following three points.

  That is, the sensor 102 that detects the rotational speed of the main shaft 20 (that is, the rotational speed of the holding member 20-2) based on driving of the motor 24 is provided. In addition, as such a sensor 102, a Hall sensor and an encoder can be used, for example.

  The determination unit 64 determines whether the cover 12a is opened or closed based on the result detected by the sensor 34, and the holding member 20-2 of the spindle 20 is fixed based on the result detected by the sensor 102. Judgment is made as to whether or not it has rotated more than the number of times.

  Furthermore, when the determination unit 64 determines that the cover 12a is opened and the holding member 20-2 has rotated a predetermined number of times, the rotation control unit 66 manually rotates the holding member 20-2. If the determination unit 64 determines that the cover 12a is closed, the motor 24 is driven to start the rotation of the holding member 20-2. Then, when the rotation of the holding member 20-2 is started, the rotation control unit 66 controls the rotation number to be increased stepwise.

In the above construction, when performing a cutting process on the workpiece by the machining apparatus according to a second embodiment of the present invention, the procedure of the processing device 1 0 according to the first embodiment of the present invention described above Cutting processing is performed.

  Next, a break-in process performed at a predetermined timing such as when the processing apparatus according to the second embodiment of the present invention is not used for a long time (for example, one month) will be described.

  First, the operator confirms that the cover 12a is closed. At this time, if the cover 12a is open, the cover 12a is closed.

  After that, when the operator performs an operation of executing a break-in process using an operator (not shown), the break-in process is started by the microcomputer 18.

  Here, the flowchart of FIG. 6 shows detailed processing contents of the break-in processing in the machining apparatus according to the second embodiment of the present invention.

  When the break-in process shown in FIG. 6 is started, first, the spindle 20 is moved to a predetermined position set in advance (step S602).

  That is, in the process of step S602, the spindle 20 is moved by the movement control unit 60 to a preset position, for example, a position where the operator can easily rotate the holding member 20-2 manually.

  Further, when the rotation speed of the holding member 20-2 is increased to 48000 rpm, time counting is newly started.

  After that, when the counted time reaches 2 minutes, the process proceeds to step S616 (described later).

  In the process of step S616, the spindle 20 is rotated at 60000 rpm for 5 minutes, and then the break-in process is terminated.

That is, in the processing of this step S616 is the rotation control unit 6 6 controls the motor 24, increases the rotational speed of the holding member 20-2 of the spindle 20 that rotates at a rotational speed 48000rpm to 60000 rpm.

  Further, when the rotation speed of the holding member 20-2 is increased to 60000 rpm, time counting is newly started.

  Thereafter, when the counted time reaches 5 minutes, the break-in processing is terminated.

  As described above, when performing the break-in process, the machining apparatus according to the second embodiment of the present invention first rotates the holding member 20-2 of the spindle 20 a predetermined number of times with respect to the operator. When the sensor 102 detects that the rotation number of the holding member 20-2 of the main shaft 20 has rotated more than a certain number of times, the operator determines that the holding member 20-2 of the main shaft 20 has been manually rotated, Thereafter, a running-in operation is performed in which the rotation speed of the holding member 20-2 of the main shaft 20 is increased stepwise.

  As a result, in the machining apparatus according to the second embodiment of the present invention, even if the grease in the bearing 20-4 is hardened, the spindle 20 is manually rotated by the operator, so that the motor 24 is excessively large. Current does not flow.

  For this reason, according to the machining apparatus according to the second embodiment of the present invention, unnecessary load is not applied to the motor 24 in the break-in process.

  The embodiment described above may be modified as shown in the following (1) to (3).

  (1) In the above-described embodiment, in the processing apparatus, in the process of step S604, after displaying on the display unit 22 that prompts the spindle 20 to be manually rotated a predetermined number of times, the process of step S606 is performed. Although it is determined whether or not the spindle 20 has rotated a predetermined number of times or more, it is needless to say that the present invention is not limited to this.

  That is, after the process of step S604, after determining whether or not the cover 12a has been opened, the process may proceed to step S606.

  That is, when the process of step S604 is completed, it is next determined whether or not the cover 12a is opened. If it is determined that the cover 12a is not closed, it is determined whether or not the cover 12a is opened again. If the determination is made and it is determined that the cover 12a is closed, the process proceeds to step S606.

  (2) In the above-described embodiment, the processing devices 10 and 100 are provided with the display unit 22 to display the display for prompting the operator to rotate the spindle 20, but the present invention is not limited to this. (Not shown) may be provided to prompt the operator to manually rotate the spindle 20 by voice guidance.

  (3) You may make it combine the above-mentioned embodiment and the modification shown in above-mentioned (1) thru | or (2) suitably.

  The present invention is suitable for use as a processing apparatus that performs cutting on a workpiece.
