Japanese Patent Application Laid-Open No. 2007-160461

In the conventional two-spindle lathe described above, the opening and closing door with a transparent window is arranged in the center of the machine body, so the operation panel can be installed for the operator standing at that position. However, in a multi-tasking machine that includes other processing equipment in addition to a pair of lathes, in addition to the opening and closing doors provided on the front of the machine body in two locations on the left and right, equipment such as an automatic tool changer is added, and an operation panel is installed. You will have to worry about the location. This is because even if the operation panel is attached to the front surface of the machine body, it becomes difficult for the operator to operate the operation panel while checking the inside of the machine if it is far from the position of the opening/closing door or the transparent window. In addition, depending on the installation location of the operation panel, the inside of the machine cannot be seen from the front, making it difficult to work using the operation panel.

Therefore, in order to solve such problems, an object of the present invention is to provide a multi-tasking machine with excellent operability of the operation panel.

A multi-tasking machine according to one aspect of the present invention includes a left front door and a right front door formed on the front surface of a body cover corresponding to left and right processing chambers, and a position between the left front door and the right front door. A peephole formed in a central cover of an automatic tool changer, an operation panel superimposed on the peephole, and the operation panel facing forward can be swung sideways. and a guide mechanism for supporting and moving the operation panel overlaid on the viewing window to any one of left and right positions.

According to the above configuration, the operation panel can be stopped at an arbitrary position moved in the left-right direction by the guide mechanism, and can be swung sideways, so that the operation panel can be moved at a position corresponding to the left front door or the right front door. The operation panel can be operated, and since the central cover of the automatic tool changer has a viewing window, even if the operation panel is placed on top of it, you can check the inside of the machine by moving it. You can operate the control panel while

The headstock 12 and the spindle motor 13 are mounted on the main slide 14 and configured to move on the bed 7 in the Z-axis direction (the axial direction of the spindle of the headstock 12) in the width direction of the machine body. In the first turret device 5 and the second turret device 6, rotation indexing of a plurality of tools T (turret tools) mounted on the turret 15 is performed by rotation control of the indexing servomotor 16. ing. The first and

second turret devices

5 and 6 each move the turret 15 in two directions, forward and backward, with a predetermined inclination perpendicular to the Z-axis in order to position the tool T at the machining position for the workpiece W. A drive mechanism is provided to allow the

The tool spindle device 2 in the center of the fuselage is installed so as to be sandwiched between the first turret device 5 and the second turret device 6. The tool spindle device 2 has a built-in type spindle head 17 in which a spindle servomotor and a tool spindle are built, and the spindle head 17 is mounted on a spindle slide 18 that can move in the vertical X-axis direction. Furthermore, a base slide 19 is configured to move on the bed 7 in the horizontal Y-axis direction, which is the longitudinal direction of the machine body, and a main shaft slide 18 is mounted thereon. The spindle head 17 is configured so that the tool (spindle head tool) T can be replaced according to the machining content, and it rotates about the B-axis parallel to the Y-axis. Note that the moving direction of the turret 15 described above is a direction inclined 45 degrees with respect to the Y-axis and the X-axis.

FIG. 2 is a perspective view of the multi-tasking machine 1 to which an automatic work transfer device and an automatic tool changer are added. The multi-tasking machine 1 is provided with an automatic tool changer 8 in the front part of the machine body, and is configured to automatically change the tool T with respect to the tool spindle device 2 . In the automatic tool changer 8, a tool magazine 21 containing a plurality of tools T (spindle head tools) is provided on the front upper part of the machine body, and the arrangement is devised so as not to occupy space inside the machine. Therefore, between the tool magazine 21 and the tool changer for exchanging the tools T of the spindle head 17, a mechanism for vertically conveying the tools is required. In this embodiment, a changer main body 22 for supporting a tool magazine 21 is provided at the center of the front face of the machine body, and a shift mechanism for vertically transporting tools is configured therein.

The multi-tasking machine 1 is also provided with an automatic work transfer device 9 for transferring and delivering the work W to the first and second

work spindle devices

3 and 4 in the machining chamber. Stockers for storing works W are provided at the entrance and exit of the multitasking machine 1 , and an automatic work transfer device 9 carries in unprocessed works W into the processing chamber and unprocessed works W out. The multitasking machine 1 has a turret-shaped frame structure 10 mounted on a bed 7 , and an automatic work transfer device 9 is a gantry-type transfer device mounted on the frame structure 10 .

FIG. 3 is an external perspective view of the multi-tasking machine 1. FIG. In the multitasking machine 1, various processing devices such as the tool spindle device 2 and the first work spindle device 3 shown in FIG. A part cover 27 is configured to protrude. An operation panel 28 is provided on a center cover 27 at the center of the machine body, and a left front door 31 and a right front door 32 are formed on the machine body cover 25 on both left and right sides thereof. In addition, in the description of the present embodiment, the specification of left and right indicates the direction when viewed from the front of the aircraft.

Behind the left front door 31 is a first machining chamber for processing the work W gripped by the first work spindle device 3 , and behind the right front door 32 is the work W gripped by the second work spindle device 4 . There is a second processing chamber for processing the By opening the left front door 31 and the right front door 32, the first processing chamber and the second processing chamber can be directly accessed by the operator from the front because transparent windows with glass are formed therein. You can see inside the plane. Therefore, the operator can operate the operation panel 28 while directly confirming the movement and movement position of each drive part regarding mechanical adjustment associated with automatic control such as movement position adjustment of the spindle chuck 11 .

On the other hand, the tool spindle device 2 is arranged in the central part of the machine body, but there is an operation panel 28 on the front face of the machine body, and the changer main body 22 is covered by the central cover 27 behind it. Therefore, in this state, the operator cannot directly see the movement and movement position of the spindle head 17 from the front. In addition, in the multi-tasking machine 1, the workpiece W is transferred between the spindle chucks 11 between the first workpiece spindle device 3 and the second workpiece spindle device 4, and the accurate transfer of the workpiece W results in high machining accuracy of the workpiece W. making it possible. Therefore, mechanical adjustment of the spindle chucks 11 is extremely important, but since the transfer position of the work W is the central portion of the machine body, the operator cannot directly see it from the front.

The multi-tasking machine 1 of this embodiment has been improved so that a worker standing in the center of the machine can directly check the inside of the machine from the front. FIG. 4 is a diagram showing the configuration thereof, and is a cross-sectional perspective view showing the left half of the magazine cover 26 and the central cover 27 of the automatic tool changer 8. As shown in FIG. The control panel 28 is assembled to swing about a vertical axis, and the drawing shows the rear surface after the swing. Normally, the operation panel 28 is arranged with the rear side overlapping the central cover 27 and facing the front as shown in FIG. can be removed from the

The central cover 27 is box-shaped and has a space for vertically moving the tool T by the shift mechanism. Therefore, a viewing window 33 (transparent window) fitted with glass is formed in the front surface 271 of the central cover 27 . Since the rear surface 272 is formed with a tool change window 34 for transferring the tool T to and from the inside of the machine, the observation window 33 is formed at a position overlapping the tool change window 34 when viewed in the front-rear direction. Therefore, in the normal state shown in FIG. 3, the observation window 33 is closed by the operation panel 28, but by swinging the operation panel 28 as shown in FIG. The inside of the machine can be seen through the tool change window 34. - 特許庁

By the way, although the worker standing in the center of the machine can see the inside of the machine in this way, it is difficult to operate it if the operation panel 28 faces the opposite direction as shown in FIG. The same can be said for the operation of the operation panel 28 performed while looking at the first processing chamber and the second processing chamber. That is, depending on the direction and distance of the operation panel 36, it becomes difficult for the operator to operate the operation panel 28 in a standing position to check the inside of the machine, resulting in a significant reduction in work efficiency. Therefore, the operation panel 28 of the multitasking machine 1 has a guide mechanism 50 that makes it easy for the operator to operate the operation panel 28 in any standing position relative to the left front door 31, the right front door 32, and the viewing window 33. It is configured.

5 is a perspective view showing the guide mechanism 50 of the operation panel 28, and FIG. 6 is a plan view showing the guide mechanism 50. FIG. The operation panel 28 is pivotally supported on the pedestal 51 so as to swing around a vertical shaft 54 on the left side. The operation panel 28 is provided with a handle 29 on the right side surface opposite to the vertical shaft 54, and can be easily swung by the operator by gripping the handle 29 and pulling it toward the operator, so that the operation panel 28 can be moved from the normal state facing the front. It can be in a horizontal state facing left. The sideways control panel 28 must be positioned on the right side of the operator who checks the inside of the machine. Therefore, the guide mechanism 50 has a structure for moving the operation panel 28 from the center of the multitasking machine 1 to the right side.

A pedestal 51 that supports the operation panel 28 is supported by a bracket 52 fixed to the right end, and the bracket 52 is further fixed to a slide member 53 to be integrated. The bracket 52 protrudes forward from the slide member 53 , and the pedestal 51 separated forward from the body cover 25 is positioned in front of the central cover 27 . In the linear guide, a slide member 53 slides along a guide rail 55. The guide rail 55 is horizontally fixed under the right front door 32 as shown in FIG. Therefore, the operation panel 28 supported by the slide member 53 is configured to move on the right side of the multitasking machine 1 .

The guide mechanism 50 can move the slide member 53 from the normal position indicated by the one-dot chain line in FIG. . 7, 8 and 9 are diagrams showing situations in which the operator operates the control panel 28 while checking the inside of the machine at different locations. First, FIG. 7 shows a case where an operator stands in front of the left front door 31 to check the inside of the first processing chamber. At this time, as shown in FIG. 3, the operation panel 28 is turned 90 degrees by the operator from the state in which it faces forward at the center, so that it faces the operator and is positioned to the right of the operator. placed.

Next, FIG. 8 shows a case where the operator stands in front of the viewing window 33 to check the central part of the machine behind the central cover 27 . At this time, when the operator grips the handle 29 and pulls the operation panel 28 to the right from the state in which the operation panel 28 faces forward at the center as shown in FIG. do. The slider 53 is stopped at a position near the center of the guide rail 55, and the operation panel 28 is turned 90 degrees there, so that the operation panel 28 located on the right side of the operator faces the operator.

FIG. 9 shows the case where the worker stands in front of the right front door 31 to check the inside of the second processing chamber. At this time as well, the operator grips the handle 29 and pulls the operation panel 28 to the right, so that the slide member 53 slides along the guide rail 55 . When the slider 53 moves to the right end of the guide rail 55 and is stopped, the operator turns the operation panel 28 by 90 degrees, so that the operation panel 28 located on the right side of the operator faces the operator.

Therefore, according to this embodiment, the operation panel 28 can be arranged on the right side facing the operator in any of the first processing chamber, the second processing chamber, and the central portion of the machine body. Therefore, the operator can operate the operation panel 28 on the spot without moving while watching the inside of the machine. The guide mechanism 50 is easy to handle because the operation panel 28 can be arranged in the states shown in FIGS.

The multi-tasking machine 1 has a tool magazine 21 at the upper part of the front face of the machine body, so that the entire structure is compact, but on the other hand, the central part of the front face of the machine body is blocked. In this respect, in the present embodiment, the center cover 27 is provided with the viewing window 33, so that the inside of the machine can be seen from the front as with the left front door 31 and the right front door 32 during work.

Although one embodiment of the present invention has been described, the present invention is not limited to this, and various modifications can be made without departing from the scope of the invention.
For example, the guide mechanism 50 of the above embodiment is configured so that the operation panel 28 is positioned on the right side of the operator. It may be configured on the left side of the machine body so as to be positioned on the left side with respect to the operator.
