[0003] [Patent Document 1] JP 2007-160461 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional two-spindle lathe, the opening door with a transparent window is located in the center of the machine, so the operation panel can be installed in that position for the worker to stand on. However, in a multi-tasking machine that includes other processing devices in addition to a pair of lathes, opening doors are provided on the left and right sides of the front of the machine, and devices such as an automatic tool changer are also added, making it difficult to find a place to install the operation panel. Even if the operation panel is installed on the front of the machine, if it is far away from the opening door and transparent window, it becomes difficult for the worker to operate the operation panel while checking the inside of the machine. Also, depending on the location of the operation panel, it is not possible to see the inside of the machine behind it from the front, making it difficult to work using the operation panel.

[0005] SUMMARY OF THE PRESENT EMBODIMENT In order to solve the above problems, an object of the present invention is to provide a multi-tasking machine having an operation panel that is easy to operate. [Means for solving the problem]

[0006] A multi-tasking machine in one embodiment of the present invention has a left front door and a right front door formed on the front of the body cover corresponding to the left and right machining chambers, a sight hole formed in the central cover of an automatic tool changer located between the left and right front doors, an operation panel arranged overlapping the sight hole, and a guide mechanism that supports the operation panel arranged facing forward so that it can be swingably turned sideways and moves the operation panel from the position overlapping the sight hole to any position on either the left or right side. Effect of the Invention

[0007] According to the above configuration, the guide mechanism allows the control panel to be moved left and right at any desired position and then swung sideways, so that the control panel can be operated at a position corresponding to the left or right front door. Furthermore, since a viewing window is formed in the central cover of the automatic tool changer, even if the control panel is stacked there, it can be moved to operate the control panel while checking the inside of the machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] An embodiment of the multi-tasking machine according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the main structure of the multi-tasking machine of this embodiment. The multi-tasking machine 1 is a machine tool having both the functions of an NC lathe and a machining center by having various processing devices. Specifically, a symmetrically arranged opposed two-axis lathe is constituted by a first work spindle device 3 and a second work spindle device 4 that grip a workpiece W, and a first turret device 5 and a second turret device 6 that have a plurality of tools, and a tool spindle device 2 is disposed at the center of the machine body.

[0010] The first and second work spindle devices 3 and 4 each have a spindle chuck 11 attached to a spindle of a headstock 12, and are rotated by the drive of a spindle motor 13, so that the gripped work W is phased during machining and rotated at a predetermined speed. The headstock 12 and the spindle motor 13 are mounted on a spindle slide 14, and are configured to move on the bed 7 in the Z-axis direction (the axial direction of the spindle of the headstock 12) in the machine body width direction. The first turret device 5 and the second turret device 6 are configured to perform turning indexing of a plurality of tools T (turret tools) attached to the turret 15 by the rotation control of an indexing servo motor 16. The first and second turret devices 5 and 6 are provided with a drive mechanism for moving the turret 15 in two directions, forward and backward, of the machine body at a predetermined inclination perpendicular to the Z-axis, in order to position the tool T at a machining position for the work W.

[0011] The tool spindle device 2 in the center of the machine body is installed 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 with a built-in spindle servo motor and a tool spindle, 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 front-rear direction of the machine body, and the spindle slide 18 is mounted on it. The spindle head 17 is capable of replacing a tool (spindle head tool) T depending on the processing content, and is configured to rotate around the B-axis parallel to the Y-axis. The movement direction of the turret 15 described above is inclined at 45 degrees with respect to the Y-axis and X-axis.

[0012] FIG. 2 is a perspective view of the multitasking machine 1 to which an automatic workpiece conveying device and an automatic tool changing device are added. The multitasking machine 1 is configured so that an automatic tool changing device 8 is provided at the front part of the machine body, and the tool T for the tool spindle device 2 is automatically changed. The automatic tool changing device 8 is arranged so that a tool magazine 21 storing a plurality of tools T (spindle head tools) is provided at the upper front part of the machine body, and is arranged so as not to occupy space inside the machine. Therefore, a mechanism for vertically conveying the tool is required between the tool magazine 21 and the tool changer that replaces the tool T of the spindle head 17. In this embodiment, an exchange device main body 22 that supports the tool magazine 21 is provided at the center of the front of the machine body, and a shift mechanism for vertically conveying the tool is configured therein.

[0013] The multitasking machine 1 is also provided with an automatic workpiece transport device 9 for transporting and transferring the workpiece W to the first and second workpiece spindle devices 3, 4 in the machining chamber. Stockers for storing the workpiece W are provided at the entrance and exit of the multitasking machine 1, and the automatic workpiece transport device 9 carries the unmachined workpiece W into the machining chamber and carries the machined workpiece W out. The multitasking machine 1 has a tower-shaped frame structure 10 assembled on the bed 7, and the automatic workpiece transport device 9 is a gantry-type transport device mounted on the frame structure 10.

[0014] Fig. 3 is an external perspective view of the multi-tasking machine 1. In the multi-tasking machine 1, various machining devices such as the tool spindle device 2 and the first workpiece spindle device 3 shown in Fig. 1 are covered by a machine body cover 25, and a magazine cover 26 and a central cover 27 that cover the automatic tool changer 8 protrude from the front of the machine body. An operation panel 28 is provided on the central cover 27 in the center of the machine body at the front 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 the left and right sides of the central cover 27. In the description of this embodiment, the left and right specifications refer to the directions when viewed from the front of the machine body.

[0015] Behind the left front door 31 is a first machining chamber in which the workpiece W held by the first workpiece spindle device 3 is machined, and behind the right front door 32 is a second machining chamber in which the workpiece W held by the second workpiece spindle device 4 is machined. By opening the left front door 31 or the right front door 32, and because a transparent window with glass fitted in it is formed in the first machining chamber or the second machining chamber, the operator can directly see inside the machine from the front. Therefore, the operator can operate the operation panel 28 while directly checking the movement and movement position of each driving part regarding machine adjustments associated with automatic control, such as adjustment of the movement position of the spindle chuck 11.

[0016] On the other hand, the tool spindle unit 2 is disposed in the center of the machine body, but there is an operation panel 28 at the front of the machine body, and behind that, the exchange unit main body 22 is covered by a center cover 27. Therefore, in this state, the operator cannot directly see the movement or moving position of the spindle head 17 from the front. Also, in the multi-tasking machine 1, the workpiece W is handed over between the spindle chucks 11 between the first workpiece spindle unit 3 and the second workpiece spindle unit 4, and this accurate handover enables high machining accuracy of the workpiece W. Therefore, although mechanical adjustment between the spindle chucks 11 is extremely important, the handover position of the workpiece W is in the center of the machine body, so the operator cannot directly see it from the front.

[0017] The multi-tasking machine 1 of this embodiment has been improved so that an operator standing at the center of the machine can directly check the inside of the machine from the front. Fig. 4 is a diagram showing the configuration, 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. The operation panel 28 is assembled so as to be swung by a vertical shaft, and the drawing shows its back surface after it has been swung. As shown in Fig. 3, the operation panel 28 is normally arranged with its back surface overlapping the central cover 27 and facing the front, but by swinging it, it can be removed from the line of sight of the operator who looks straight into the interior of the machine.

[0018] The central cover 27 is box-shaped, and has a space for moving the tool T up and down by the shift mechanism. Therefore, a sight window 33 (transparent window) with glass fitted therein is formed in the front surface 271 of the central cover 27. Since a tool exchange window 34 for transferring the tool T between the inside of the machine and the rear surface 272 is formed, the sight window 33 is formed at a position overlapping the tool exchange window 34 when viewed in the front-rear direction. Therefore, in the normal state shown in Fig. 3, the sight window 33 is blocked by the operation panel 28, but by swinging the operation panel 28 as shown in Fig. 4, the operator can see inside the machine through the sight window 33 and the tool exchange window 34.

[0019] Although it is now possible for an operator standing in the center of the machine to see inside the machine, it is difficult to operate the operation panel 28 if it faces the opposite direction as shown in Fig. 4. The same can be said about the operation of the operation panel 28 while looking inside the first machining chamber or the second machining chamber. That is, depending on the direction or distance of the operation panel 36, it becomes difficult for the operator to operate the operation panel 28 while standing to check the inside of the machine, resulting in a significant decrease in work efficiency. Therefore, the operation panel 28 of the multi-function machining center 1 is configured with a guide mechanism 50 that makes it easy for the operator to operate the operation panel 28 regardless of the standing position relative to the left front door 31, the right front door 32, and the observation window 33.

[0020] FIG. 5 is a perspective view showing a guide mechanism 50 for the operation panel 28, and FIG. 6 is a plan view showing the guide mechanism 50. The operation panel 28 is supported on a base 51 so as to be pivoted about a vertical shaft 54 ​​on the left side. The operation panel 28 is provided with a handle 29 on the right side opposite the vertical shaft 54, and the operator can easily pivot the operation panel 28 by grasping the handle 29 and pulling it toward himself, thereby changing the operation panel 28 from a normal state facing forward to a horizontal state facing left. In the horizontal state, the operation panel 28 needs to be located on the right side of the operator checking the inside of the machine. Therefore, the guide mechanism 50 has a structure that moves the operation panel 28 from the center of the multi-tasking machine 1 to the right side.

[0021] The base 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 form a single unit. The bracket 52 protrudes forward from the slide member 53, and the base 51, which is separated forward from the machine body cover 25, is located in front of the central cover 27. The linear guide is such that the slide member 53 slides on a guide rail 55, and the guide rail 55 is fixed horizontally below the right front door 32 as shown in FIG. 3. Therefore, the operation panel 28 supported by the slide member 53 is configured to move along the right side of the multi-purpose machine 1.

[0022] The guide mechanism 50 can move the slide member 53 from a normal position shown by a dashed line in Fig. 6 to a right end position shown by a solid line, and can stop the slide member 53 at any position therebetween to operate the operation panel 28. Figs. 7, 8, and 9 are diagrams showing situations in which an operator operates the operation panel 28 while checking the inside of the machine at different positions. First, Fig. 7 shows a case in which an operator stands in front of the left front door 31 to check the inside of the first machining chamber. At this time, the operation panel 28 is rotated by 90 degrees by the operator from a state facing forward in the center as shown in Fig. 3, so that the operation panel 28 faces the operator and is located to the right of the operator.

[0023] Next, Fig. 8 shows a case where an operator stands in front of the sight hole 33 to check the central part of the interior of the machine behind the central cover 27. At this time, the operator grasps the handle 29 and pulls the operation panel 28 to the right from the state facing forward in the center as shown in Fig. 3, causing the slide member 53 to slide and move on the guide rail 55. The slider 53 is stopped at a position near the center of the guide rail 55, and the operation panel 28 is rotated 90 degrees at this point, so that the operation panel 28 located to the right of the operator is faced toward the operator.

[0024] 9 shows the case where an operator stands in front of the right front door 31 to check the inside of the second machining chamber. In this case, the operator also grasps the handle 29 and pulls the operation panel 28 to the right, causing the slide member 53 to slide and move on the guide rail 55. The slider 53 is stopped at the position where it has moved to the right end of the guide rail 55, and the operator turns the operation panel 28 by 90 degrees, so that the operation panel 28 located to the operator's right is faced toward the operator.

[0025] Therefore, according to this embodiment, the operation panel 28 can be placed on the right side facing the operator in any of the first processing chamber, the second processing chamber, and the center of the machine body. Therefore, the operator can operate the operation panel 28 on the spot while looking inside the machine without moving. The guide mechanism 50 is easy to handle because the operator can position the operation panel 28 in the states shown in Figures 7 to 9 by gripping the handle 29 and sliding or swinging it.

[0026] Although the multi-tasking machine 1 has a compact overall structure due to the tool magazine 21 being provided at the top front of the machine body, the center of the front of the machine body is obstructed. In this embodiment, however, a viewing window 33 is formed in the center cover 27, so that it is possible to work while looking inside the machine from the front, just like the left front door 31 and the right front door 32.

[0027] Although one embodiment of the present invention has been described, the present invention is not limited to this embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, the guide mechanism 50 in the above embodiment is configured so that the operation panel 28 is located to the right of the operator, but this is because it takes into consideration that the majority of people are right-handed; for other reasons, it may be configured so that the operation panel 28 is located on the left side of the machine body so as to be positioned to the left of the operator.
