Description

[Technical Field]

[0001] The present invention relates to a machine tool and an index member. [Background technology]

[0002] There is known a machine tool in which two processing devices for processing a workpiece are installed side by side in the left-right direction (see, for example, Patent Document 1). In this machine tool, the two processing devices are installed separately on the floor of a building, so that vibrations generated by one processing device are prevented from being transmitted to the other processing device, and the processing accuracy of the workpiece can be improved by each of the two processing devices.

[0004] When installing the above-mentioned machine tools on the floor of a building or the like, it is necessary to precisely align the two processing devices. For example, even if the two processing devices are precisely aligned and connected with a connecting plate or the like at the time of product shipment, removing the connecting plate after installation can cause relative misalignment between the two processing devices, which may exceed the tolerance. If the relative misalignment between the two processing devices exceeds the tolerance, it can cause, for example, misalignment of the workpiece during transport in a loader device that transports workpieces between the two processing devices, which is undesirable. Furthermore, the relative misalignment between the two processing devices can occur not only in the left-right direction but also in the up-down and front-back directions. Of these directions, it is required that the relative misalignment in at least the left-right and up-down directions can be easily confirmed after the two processing devices are installed.

[0005] An object of the present invention is to provide a machine tool and an index member that make it possible to easily check the relative positional deviations in the vertical and horizontal directions between two processing devices in the machine tool. [Means for solving the problem]

The indicator member further includes a connection piece that connects the first member and the second member and is detachable from each of the first member and the second member. [Effects of the Invention]

[0008] According to the machine tool and index member of the above aspect, when two processing devices are installed side by side in the left-right direction, the first member and the second member are arranged side by side. Therefore, by checking the first vertical index portion of the first member and the second vertical index portion of the second member, the relative positions of the two processing devices in the up-down direction can be easily confirmed. Furthermore, by checking the first horizontal index portion of the first member and the second horizontal index portion of the second member, the relative positions of the two processing devices in the left-right direction can be easily confirmed. In other words, by looking at the first member and the second member, the worker can easily confirm the deviations in the relative positions of the two processing devices in the up-down direction and the left-right direction.

[0009] In the machine tool of the above aspect, the first and second vertical indicator portions may each be provided extending in the left-right direction, and the two processing devices may be positioned relative to each other in the vertical direction by aligning the first and second vertical indicator portions in a straight line or nearly in a straight line in the left-right direction. The first and second horizontal indicator portions may each be provided extending in the vertical direction, and the two processing devices may be positioned relative to each other in the vertical direction by aligning the first and second horizontal indicator portions in a straight line or nearly in a straight line. With this configuration, by checking the degree of deviation from a straight line or nearly in a straight line between the first and second vertical indicator portions, it is possible to easily check the vertical deviation of the two processing devices from the intended relative position. Furthermore, by checking the degree of deviation from a straight line or nearly in a straight line between the first and second horizontal indicator portions, it is possible to easily check the horizontal deviation of the two processing devices from the intended relative position.

[0010] In the machine tool of the above aspect, at least one of the first vertical indicator and the second vertical indicator may be provided to include a vertical deviation tolerance of the relative positions of the two processing devices in the vertical direction, and at least one of the first left-right indicator and the second left-right indicator may be provided to include a horizontal deviation tolerance of the relative positions of the two processing devices in the horizontal direction. With this configuration, it can be easily determined whether the deviations of the relative positions of the two processing devices in the vertical direction and the horizontal direction are within the tolerance ranges.

[0011] In the machine tool of the above aspect, at least one of the first vertical indicator portion and the second vertical indicator portion may be a vertical slit cut out in the vertical direction, the width of the vertical slit indicating the vertical misalignment tolerance, and at least one of the first left-right indicator portion and the second left-right indicator portion may be a left-right slit cut out in the left-right direction, the width of the left-right slit indicating the left-right misalignment tolerance. With this configuration, the misalignment tolerance can be determined using the slit width, thereby simplifying the configurations of the first vertical indicator portion and the second vertical indicator portion, and the first left-right indicator portion and the second left-right indicator portion.

[0012] Furthermore, in the machine tool of the above aspect, the first member may include a first extending portion extending in a front-to-rear direction perpendicular to the left-to-right direction in a horizontal plane, and a first front-to-rear indicator portion on the first extending portion that indicates a predetermined position in the front-to-rear direction, and the second member may include a second extending portion extending in the front-to-rear direction alongside the first extending portion, and a second front-to-rear indicator portion on the second extending portion that indicates the predetermined position in the front-to-rear direction, and the relative positions of the first front-to-rear indicator portion and the second front-to-rear indicator portion indicate the relative positions of the two processing devices in the front-to-rear direction. With this configuration, it is possible to easily check the relative positional deviations of the two processing devices in the front-to-rear direction in addition to the deviations in the relative positions in the up-and-down and left-to-right directions.

[0013] Furthermore, in the machine tool of the above aspect, the first and second longitudinal indicators may be provided so as to extend in the longitudinal direction, and the two processing devices may be positioned in a desired relative position in the longitudinal direction by aligning the first and second longitudinal indicators in a straight line or nearly in a straight line in the longitudinal direction. With this configuration, by checking the degree of deviation from a state in which the first and second longitudinal indicators are aligned in a straight line or nearly in a straight line, it is possible to easily check the longitudinal deviation of the two processing devices from the desired relative position.

[0014] Furthermore, in the machine tool of the above aspect, at least one of the first longitudinal indicator and the second longitudinal indicator may be provided to include a longitudinal deviation tolerance of the relative positions of the two processing devices in the longitudinal direction. With this configuration, it is possible to easily determine whether the deviation of the relative positions of the processing devices in the longitudinal direction is within a tolerable range. Furthermore, in the machine tool of the above aspect, at least one of the first longitudinal indicator and the second longitudinal indicator may be a longitudinal slit cut out in the longitudinal direction, and the width of the longitudinal slit may indicate the longitudinal deviation tolerance. With this configuration, the slit width can be used to determine the deviation tolerance in the longitudinal direction, thereby simplifying the configuration of the first longitudinal indicator and the second longitudinal indicator.

[0015] Furthermore, the index member of the above aspect may further include a connecting piece that connects the first member and the second member and is detachable from each of the first member and the second member. With this configuration, by attaching the index member to the machine tool after determining the relative positions of the two processing devices in advance, the intended relative positions of the two processing devices can be easily set with respect to the first member and the second member, which contributes to improving the efficiency of the index member attachment work.

[0017] The present invention will be described below through embodiments, but the following embodiments do not limit the scope of the invention claimed. Furthermore, not all combinations of features described in the embodiments are necessarily essential to the solution of the invention. In the drawings, identical or similar parts may be denoted by the same reference numerals, and redundant description may be omitted. The shapes and sizes of elements in the drawings may be exaggerated for clarity, and may differ from the shapes and dimensions of the actual product. In the drawings, directions may be described using an XYZ coordinate system. In the XYZ coordinate system, a plane parallel to the horizontal plane is the XZ plane. One direction in this XZ plane is referred to as the X direction, and the direction perpendicular to the X direction is referred to as the Z direction. The direction perpendicular to the XZ plane is referred to as the Y direction. The X, Y, and Z directions are described by assuming that the direction indicated by the arrow in the drawing is the + direction, and the direction opposite to the arrow is the - direction.

[0018] [First embodiment] FIG. 1 is a diagram showing an example of an index member 20 and a machine tool 1 according to the first embodiment. As shown in FIG. 1, the machine tool 1 includes two processing devices 10A and 10B and an index member 20. In the machine tool 1, the two processing devices 10A and 10B are installed separately on the floor of a building. The machine tool 1 is, for example, a parallel twin-axis lathe. However, the machine tool 1 is not limited to a parallel twin-axis lathe and includes other configurations in which the two processing devices 10A and 10B that machine a workpiece W are installed separately. In FIG. 1, the Z direction is the front-to-rear direction of the machine tool 1, the -Z side of the machine tool 1 is the front, and the +Z side is the back. Furthermore, the ±X sides of the machine tool 1 are the sides, and the X direction is the left-to-right direction of the machine tool 1. The Y direction is the up-and-down direction of the machine tool 1.

[0019] The two processing devices 10A and 10B each have the same configuration. The two processing devices 10A and 10B are installed side by side in the left-right direction. Of the two processing devices 10, the left side (+X side) of the two processing devices 10, as viewed from the front (as viewed from the -Z side), is referred to as processing device 10A, and the right side (-X side) of the two processing devices 10, as viewed from the front (as viewed from the -Z side), is referred to as processing device 10B. In addition, components of the processing device 10A are designated with the suffix "A," and components of the processing device 10B are designated with the suffix "B," so that multiple components of the same type can be distinguished from one another. Each processing device 10A and 10B includes a bed 11A, 11B, a level adjustment unit 12A, 12B, a spindle 13A, 13B, and a tool post 14A, 14B, respectively.

[0020] The bed 11A has a base 110A and a support portion 111A. The base 110A is placed on the floor surface by a level adjustment portion 12A. The support portion 111A is fixed onto the base 110A. The base 110A and the support portion 111A may be formed integrally. The support portion 111A supports the spindle 13A and the tool rest 14A. The bed 11B has a base 110B and a support portion 111B. The base 110B is placed on the floor surface by a level adjustment portion 12B. The base 110B and the support portion 111B have the same configuration as the base 110A and the support portion 111A of the bed 11A. The support portion 111B supports the spindle 13B and the tool rest 14B. The bed 11A and the bed 11B are arranged side by side in the left-right direction, and are spaced apart so as to leave a predetermined gap between them.

[0021] The level adjustment unit 12A is capable of leveling the bed 11A, for example, to adjust it so that it is horizontal. In this embodiment, leveling is used to adjust the posture of the bed 11A, including the vertical position of the bed 11A, the tilt around the X-axis, and the tilt around the Z-axis. The level adjustment units 12A are provided near each of the four corners on the underside of the bed 11A. The level adjustment unit 12A uses, for example, a leveling bolt, and by rotating the leveling bolt around the vertical axis, the position of the lower end is raised or lowered to adjust the posture of the bed 11A. The level adjustment unit 12B is capable of leveling the bed 11B, for example, to adjust it so that it is horizontal. Note that the level adjustment unit 12B is similar to the level adjustment unit 12A, and therefore a description thereof will be omitted. Here, leveling is performed for both the bed 11A and the bed 11B. For example, when leveling, a user places a spirit level on each of base 15A fixed to bed 11A shown in FIG. 1 and base 15B fixed to bed 11B, and uses level adjustment unit 12A and level adjustment unit 12B, respectively, to adjust bed 11A and bed 11B so that they are level.

[0022] The spindle 13A of the processing device 10A is rotatable about the axis of a rotation axis AX by a drive source such as a motor (not shown). The rotation axis AX of the spindle 13A is parallel to the Z direction. The end of the spindle 13A on the -Z side is provided with multiple gripping jaws 131A called a chuck for gripping the workpiece W. The gripping jaws 131A are arranged at predetermined intervals around the rotation axis AX of the spindle 13A. The gripping jaws 131A can grip or release the workpiece W by moving in the radial direction of the spindle 13A. The spindle 13B and gripping jaws 131B of the processing device 10B have the same configuration as the spindle 13A and gripping jaws 131A described above, so their description will be omitted.

[0023] Tool rests 14A and 14B are installed alongside spindles 13A and 13B in the X direction. In the example shown in FIG. 1, tool rest 14A is located on the +X side of spindle 13A, and tool rest 14B is located on the -X side of spindle 13B. Tool rests 14A and 14B can each rotate around an axis parallel to the Z direction by a rotation drive device (not shown), such as a motor. Tool rests 14A and 14B can also each move in the X and Z directions by a drive device (not shown).

[0024] One or more holders 141A for holding cutting tools are provided on the peripheral surface of the tool rest 14A. Cutting tools 142A are held in all or some of these holders 141A. A desired cutting tool 142A is selected by rotating the tool rest 14A. The cutting tool 142A is exchangeable with respect to the holder 141A. As the cutting tool 142A, a turning tool such as a cutting tool for cutting the workpiece W, or a rotary tool such as a drill or an end mill may be used. The cutting tool 142A of the tool rest 14A moves in the X and Z directions together with the tool rest 14A as the tool rest 14A moves in the X and Z directions. Note that the holder 141B and cutting tool 142B of the tool rest 14B are similar to the holder 141A and cutting tool 142A described above, and therefore description thereof will be omitted.

[0025] The processing device 10A performs cutting on the workpiece W held and rotating by the spindle 13A while moving the cutting tool 142A on the tool rest 14A. The processing device 10B performs cutting on the workpiece W held and rotating by the spindle 13B while moving the cutting tool 142B on the tool rest 14B.

[0026] The index member 20 is attached to a machine tool 1 in which two processing devices 10A and 10B are installed side by side in the left-right direction. The index member 20 has a shape that allows it to identify deviations in the relative positions of the two processing devices 10A and 10B in the up-down and left-right directions. FIG. 2 is a diagram showing an example of the index member 20. As shown in FIG. 2, the index member 20 includes a first member 21A and a second member 21B. The index member 20 may also be referred to as a plate member, a marker, or an index plate, for example. The index member 20 is formed from a material such as metal, resin, wood, or paper. The first member 21A is a plate-shaped member attached to one of the two processing devices 10A and 10B. In this embodiment, the first member 21A is attached to the processing device 10A. The first member 21A is fixed to the bed 11A by a bolt BL. However, the first member 21A may be fixed to the bed 11A by a method other than fixing with the bolt BL (for example, double-sided tape, etc.).

[0027] The first member 21A includes a first vertical indicator portion 30A and a first left-right indicator portion 40A. The first vertical indicator portion 30A indicates a predetermined position in the vertical direction of the processing device 10A. In this embodiment, the first vertical indicator portion 30A is a slit (hereinafter referred to as a "first vertical slit") that extends in the left-right direction and is cut out in the left-right direction. The width ΔY1 of this first vertical slit indicates the allowable amount of deviation in the relative positions of the two processing devices 10A and 10B in the vertical direction (hereinafter referred to as the "allowable vertical deviation amount"). The first left-right indicator portion 40A indicates a predetermined position in the left-right direction of the processing device 10A. The first left-right indicator portion 40A is a slit (hereinafter referred to as a "first left-right slit") that extends in the left-right direction and is cut out in the up-down direction. The width ΔX1 of the first left-right slit indicates the tolerance for deviation of the relative positions of the two processing devices 10A and 10B in the left-right direction (hereinafter referred to as "left-right deviation tolerance").

[0028] The second member 21B is a plate-shaped member attached to the other of the two processing devices 10A, 10B. In this embodiment, the second member 21B is attached to the processing device 10B. The second member 21B is provided next to the first member 21A in the left-right direction and is attached to the processing device 10B so as to be spaced apart from the first member 21A. The second member 21B is fixed to the bed 11B with bolts BL. However, the second member 21B may be fixed to the bed 11B by a method other than fixing with bolts BL (for example, double-sided tape, etc.).

[0029] The second member 21B includes a second vertical indicator portion 30B and a second left-right indicator portion 40B. The second vertical indicator portion 30B indicates a predetermined position in the vertical direction of the processing device 10B. The second vertical indicator portion 30B is a slit (hereinafter referred to as a "second vertical slit") that extends in the left-right direction and is cut out in the left-right direction. The width ΔY2 of this second vertical slit indicates the allowable vertical deviation of the relative positions of the two processing devices 10A, 10B in the vertical direction. In this embodiment, the width ΔY1 of the first vertical slit and the width ΔY2 of the second vertical slit are the same, but this is not limited to this embodiment and the width ΔY1 and the width ΔY2 may be different.

[0030] The second left / right indicator portion 40B indicates a predetermined position in the left / right direction of the processing device 10B. The second left / right indicator portion 40B is a slit (hereinafter referred to as the "second left / right slit") that extends in the vertical direction and is cut out in the vertical direction. The width ΔX2 of the second left / right slit indicates the left / right misalignment tolerance, which is the tolerance for misalignment of the relative positions of the two processing devices 10A, 10B in the left / right direction. In this embodiment, the width ΔX1 of the first left / right slit and the width ΔX2 of the second left / right slit are the same, but the width ΔX1 and the width ΔX2 may be different.

[0031] Next, a method for checking the vertical positional deviation of the processing devices 10A and 10B relative to each other using the indicator member 20 will be described. Fig. 3 is a diagram for explaining a method for checking the vertical positional deviation of the processing devices 10A and 10B relative to each other. The first vertical indicator part 30A and the second vertical indicator part 30B form a pair as means for indicating the vertical relative positions of the processing devices 10A and 10B.

[0032] When there is no misalignment in the relative positions of the processing apparatus 10A and the processing apparatus 10B in the vertical direction, the first member 21A and the second member 21B are fixed so that the first vertical indicator portion 30A and the second vertical indicator portion 30B are aligned in a straight line or approximately aligned in a straight line in the left-right direction (see FIG. 2). This state is the intended relative position (or desired relative position, or appropriate relative position) of the processing apparatus 10A and the processing apparatus 10B in the vertical direction. Therefore, if there is a misalignment in the vertical direction between the first vertical indicator portion 30A and the second vertical indicator portion 30B, that misalignment indicates a misalignment in the relative positions of the processing apparatus 10A and the processing apparatus 10B in the vertical direction.

[0033] Here, at least one of the first vertical indicator portion 30A and the second vertical indicator portion 30B includes a vertical misalignment tolerance. Therefore, if the vertical misalignment between the first vertical indicator portion 30A and the second vertical indicator portion 30B exceeds the vertical misalignment tolerance, it indicates that the vertical misalignment between the processing apparatus 10A and the processing apparatus 10B exceeds the tolerance. On the other hand, if the vertical misalignment between the first vertical indicator portion 30A and the second vertical indicator portion 30B does not exceed the vertical misalignment tolerance, it indicates that the vertical misalignment between the processing apparatus 10A and the processing apparatus 10B is within the tolerance.

[0034] For example, as shown in FIG. 3A, even if a vertical misalignment occurs between the first and second indicator portions 30A and 30B, as long as portions of the first and second indicator portions 30A and 30B face each other in the left-right direction, the vertical misalignment between the first and second indicator portions 30A and 30B does not exceed the allowable vertical misalignment amount. In other words, as long as the upper portion (30AH or 30BH) of one of the first and second indicator portions 30A and 30B does not exceed the lower portion (30AL or 30BL) of the other, the vertical misalignment between the first and second indicator portions 30A and 30B does not exceed the allowable vertical misalignment amount. Therefore, the state shown in FIG. 3A indicates that the vertical misalignment between the processing apparatus 10A and 10B is within the allowable range.

[0035] On the other hand, as shown in FIG. 3(B), when the first and second indicator portions 30A and 30B are not all facing each other in the left-right direction, the vertical misalignment between the first and second indicator portions 30A and 30B exceeds the allowable vertical misalignment amount. In other words, the upper portions (30AH and 30BH) of the first and second indicator portions 30A and 30B exceed the lower portions (30AL and 30BL), which indicates that the vertical misalignment between the first and second indicator portions 30A and 30B exceeds the allowable vertical misalignment amount. Therefore, the state shown in FIG. 3(B) indicates that the vertical misalignment between the processing apparatus 10A and 10B exceeds the allowable range.

[0036] Next, a method for checking the deviation in the relative position of the processing devices 10A and 10B in the left-right direction using the indicator member 20 will be described. Fig. 4 is a diagram for explaining a method for checking the deviation in the relative position of the processing devices 10A and 10B in the left-right direction. The first left-right indicator portion 40A and the second left-right indicator portion 40B form a pair as means for indicating the relative position of the processing devices 10A and 10B in the left-right direction.

[0037] When there is no misalignment in the relative positions of the processing apparatus 10A and the processing apparatus 10B in the left-right direction, the first member 21A and the second member 21B are fixed so that the first left-right indicator portion 40A and the second left-right indicator portion 40B are aligned in a straight line or approximately aligned in a straight line in the up-down direction (see FIG. 2). This state is the intended relative positions of the processing apparatus 10A and the processing apparatus 10B in the left-right direction. Therefore, if there is a misalignment in the left-right direction between the first left-right indicator portion 40A and the second left-right indicator portion 40B, that misalignment indicates a misalignment in the relative positions of the processing apparatus 10A and the processing apparatus 10B in the left-right direction.

[0038] Here, at least one of the first left-right indicator portion 40A and the second left-right indicator portion 40B includes a left-right misalignment tolerance. Therefore, if the left-right misalignment between the first left-right indicator portion 40A and the second left-right indicator portion 40B exceeds the left-right misalignment tolerance, it indicates that the misalignment in the relative left-right position between the processing device 10A and the processing device 10B exceeds the tolerance. On the other hand, if the left-right misalignment between the first left-right indicator portion 40A and the second left-right indicator portion 40B does not exceed the left-right misalignment tolerance, it indicates that the misalignment in the relative left-right position between the processing device 10A and the processing device 10B is within the tolerance.

[0039] For example, as shown in FIG. 4A, even if a misalignment occurs between the first and second left and right indicators 40A and 40B in the left-right direction, as long as portions of the first and second left and right indicators 40A and 40B face each other in the up-down direction, the misalignment between the first and second left and right indicators 40A and 40B does not exceed the allowable misalignment amount. In other words, as long as the left side portion (40AL or 40BL) of one of the first and second left and right indicators 40A and 40B does not exceed the right side portion (40AR or 40BR) of the other, the misalignment between the first and second left and right indicators 40A and 40B does not exceed the allowable misalignment amount. Therefore, the state shown in FIG. 4A indicates that the misalignment between the processing apparatus 10A and 10B in the left-right direction is within the allowable range.

[0040] On the other hand, as shown in FIG. 4(B), when the first and second left and right indicator portions 40A and 40B are not all facing each other in the up-down direction, the left-right misalignment between the first and second left and right indicator portions 40A and 40B exceeds the allowable left-right misalignment amount. In other words, the left portions (40AL and 40BL) of the first and second left and right indicator portions 40A and 40B exceed the right portions (40AR and 40BR), indicating that the left-right misalignment between the first and second left and right indicator portions 40A and 40B exceeds the allowable left-right misalignment amount. Therefore, the state shown in FIG. 4(B) indicates that the misalignment in the relative left-right position between the processing device 10A and the processing device 10B exceeds the allowable range.

[0041] If the relative positions of the processing apparatus 10A and the processing apparatus 10B in the vertical and horizontal directions exceed the allowable vertical and horizontal misalignment limits, an adjustment by the operator is required. The operator adjusts the vertical relative position by, for example, operating the level adjustment units 12A and 12B of the processing apparatus 10A or the processing apparatus 10B. The horizontal adjustment is performed by moving the processing apparatus 10A or the processing apparatus 10B. During such adjustments, the operator can easily adjust the vertical relative position by looking at the first vertical indicator unit 30A and the second vertical indicator unit 30B. Similarly, the operator can easily adjust the horizontal relative position by looking at the first horizontal indicator unit 40A and the second horizontal indicator unit 40B.

[0042] As described above, the index member 20 must be fixed to the processing apparatus 10A and the processing apparatus 10B without any misalignment in the vertical and horizontal directions relative to each other. For example, when shipping a product, the processing apparatus 10A and the processing apparatus 10B are accurately positioned and fixed with a connecting plate or the like. The index member 20 is then attached in this state, but if the first member 21A and the second member 21B are separate, there is a risk that the index member 20 may be fixed in a position that is different from the intended relative position described above, depending on the skill level of the worker who attaches the index member 20. Therefore, it is preferable that the first member 21A and the second member 21B are connected when attaching the index member 20.

[0043] FIG. 5 is a diagram showing an example of an index member 20 having a connecting piece 22. The index member 20 shown in FIG. 5 has a first member 21A, a second member 21B, and a connecting piece 22. The index member 20 may be formed by integrally forming the first member 21A, the second member 21B, and the connecting piece 22 by laser processing or the like. The connecting piece 22 connects the first member 21A and the second member 21B so that the first member 21A and the second member 21B maintain a desired relative position. The connecting piece 22 is connected to the first member 21A and the second member 21B by a plurality of joint portions 23, and can be separated from the first member 21A and the second member 21B by cutting these joint portions 23.

[0044] For example, the index member 20 shown in Fig. 5 is attached to the machine tool 1 in a state where there is no misalignment in the relative positions of the processing devices 10A and 10B in the up-down and left-right directions. Thereafter, the connecting piece 22 is manually or otherwise separated, so that the index member 20 becomes the separated first member 21A and second member 21B as shown in Fig. 2, and it becomes possible to identify any misalignment in the relative positions of the two processing devices 10A and 10B.

[0045] Next, a method for installing the machine tool 1 using the index member 20 according to this embodiment will be described. FIG. 6 is a flowchart showing an example of the method for installing the machine tool 1. As shown in FIG. 6, first, when the machine tool 1 is transported to the destination (customer), pre-shipment work of steps S101 to S104 shown below is performed at the shipper. In the pre-shipment work, the processing apparatus 10A and the processing apparatus 10B are leveled while adjusting any deviation in their relative positions (step S101). In step S101, an operator at the shipper uses predetermined adjustment tools and devices to adjust the relative positions of the processing apparatus 10A and the processing apparatus 10B in the vertical and horizontal directions so that there is no deviation. In addition, the operator uses level adjustment units 12A and 12B to level the beds 11A and 11B while checking a spirit level or the like.

[0046] Next, the worker performs leveling and positioning, and then attaches the connecting plate 100 (step S102). In step S102, as shown in FIG. 7, the bed 11A and the bed 11B are connected by the connecting plate 100. The connecting plate 100 is fixed to the bed 11A and the bed 11B with bolts BL, thereby connecting the bed 11A and the bed 11B. Next, after connecting the bed 11A and the bed 11B with the connecting plate 100, the worker attaches the index member 20 to the machine tool 1 (step S103). As a result, the index member 20 is attached to the machine tool 1 with the two processing devices 10A and 10B positioned relative to each other in the vertical and horizontal directions. Next, the worker cuts the joint portion 23 to separate the connecting piece 22 from the index member 20 (step S104). In step S104, the worker can easily separate the connection piece 22 by, for example, bending the connection piece 22 to break the joint portion 23. By step S104, the index member 20 is in a state in which the first member 21A and the second member 21B are separated, as shown in Fig. 8. Note that the separation of the connection piece 22 in step S104 described above may be performed at the shipping destination.

[0047] Next, machine tool 1 is shipped to the destination (step S105). In step S105, machine tool 1 is transported with bed 11A and bed 11B connected by connecting plate 100. Note that before shipping, machine tool 1 may be started up (for test machining, etc.) at the shipping source. In this case, connecting plate 100 is temporarily removed, but after start-up, connecting plate 100 is reattached to machine tool 1, and machine tool 1 is shipped to the destination. Next, when machine tool 1 is carried to the destination, machine tool 1 is installed at a predetermined position at the destination (step S106). In step S106, machine tool 1 is still in a state where bed 11A and bed 11B are connected by connecting plate 100.

[0048] Next, the worker removes the connecting plate 100 (step S107). As shown in FIG. 9, removing the connecting plate 100 from the machine tool 1 separates the beds 11A and 11B. That is, the processing apparatuses 10A and 10B are separated. If the installation surface of the machine tool 1 is uneven or inclined, a deviation in the relative positions of the processing apparatuses 10A and 10B may occur. Therefore, the worker adjusts the deviation in the relative positions of the processing apparatuses 10A and 10B while watching the indicator member 20, and also levels the beds 11A and 11B while watching the spirit level (step S108). In step S108, at the shipping destination, the worker checks the deviation in the relative positions by watching the first vertical indicator portion 30A and the second vertical indicator portion 30B and the first left-right indicator portion 40A and the second left-right indicator portion 40B of the indicator member 20, and adjusts them to eliminate the deviation in the relative positions. For example, to eliminate the misalignment, the worker adjusts one or both of the two processing devices 10A, 10B in the vertical direction using the level adjustment units 12A, 12B and adjusts by moving them in the horizontal direction. When making these adjustments, the worker can easily check whether the adjustments are within the range of the vertical misalignment allowance and the horizontal misalignment allowance by appropriately looking at the index member 20.

[0049] In step S108, the worker uses a spirit level to level the beds 11A and 11B at the shipping destination. In step S108, the worker adjusts the relative position of the processing apparatus 10A and 10B and levels the beds 11A and 11B as a series of tasks. Note that because the leveling is performed for each of the beds 11A and 11B, a misalignment may occur between the beds 11A and 11B, i.e., the relative position between the processing apparatus 10A and 10B. Next, the worker determines whether the misalignment between the relative positions of the processing apparatus 10A and 10B is within the allowable range (step S109). In step S109, the worker looks at the first vertical indicator 30A and the second vertical indicator 30B to determine whether the misalignment is within the allowable vertical misalignment range. The worker also looks at the first horizontal indicator 40A and the second horizontal indicator 40B to determine whether the misalignment is within the allowable horizontal misalignment range.

[0050] In step S109, the worker looks at the first vertical indicator 30A and the second vertical indicator 30B and determines that the vertical positional deviation between the processing apparatus 10A and the processing apparatus 10B is within the allowable range if the vertical deviation is within the allowable range as shown in FIG. 3(A). Furthermore, if the first vertical indicator 30A and the second vertical indicator 30B are outside the allowable range as shown in FIG. 3(B), the worker determines that the vertical positional deviation between the processing apparatus 10A and the processing apparatus 10B is outside the allowable range. In this way, the worker can easily confirm the vertical relative positions of the two processing apparatuses 10A and 10B based on the first vertical indicator 30A and the second vertical indicator 30B.

[0051] In step S109, the worker looks at the first left-right indicator 40A and the second left-right indicator 40B and determines that the misalignment of the relative left-right positions of the processing apparatus 10A and the processing apparatus 10B is within the allowable range if the misalignment is within the allowable range as shown in FIG. 4A. Furthermore, the worker determines that the misalignment of the relative left-right positions of the processing apparatus 10A and the processing apparatus 10B is outside the allowable range if the first left-right indicator 40A and the second left-right indicator 40B are outside the allowable range as shown in FIG. 4B. In this way, the worker can easily confirm the relative left-right positions of the two processing apparatuses 10A and 10B based on the first left-right indicator 40A and the second left-right indicator 40B.

[0052] If the relative position between the processing device 10A and the processing device 10B deviates from one or both of the vertical and horizontal deviation tolerances (NO in step S109), the process returns to step S108, and the worker adjusts the deviation in the relative position between the processing device 10A and the processing device 10B while looking at the indicator member 20, and levels the bed 11A and the bed 11B while looking at the spirit level.

[0053] Furthermore, if the deviation in the relative position between processing apparatus 10A and processing apparatus 10B is within the allowable range (YES in step S109), processing apparatus 10A and processing apparatus 10B are restored to their pre-shipment states on the installation surface of the shipping destination (step S110). That is, as shown in step S101 above, the arrangement of processing apparatus 10A and processing apparatus 10B set at the shipping source is restored (reproduced) on the installation surface (floor) of the shipping destination. In step S110, the pre-shipment states of processing apparatus 10A and processing apparatus 10B are restored on the installation surface of the shipping destination, thereby completing the installation of machine tool 1.

[0054] After the machine tool 1 is installed, the operator may check at regular intervals (or during maintenance of the machine tool 1) whether or not there is any misalignment between the two processing devices 10A and 10B by looking at the index member 20.

[0055] As described above, according to this embodiment, it is possible to easily check the misalignment of the relative positions of the two processing devices 10A, 10B in the vertical and horizontal directions by using the first vertical indicator portion 30A and the second vertical indicator portion 30B and the first left-right indicator portion 40A and the second left-right indicator portion 40B of the indicator member 20. Furthermore, when adjusting the misalignment, it is possible to easily check whether the misalignment has fallen within the allowable range by using the first vertical indicator portion 30A and the second vertical indicator portion 30B and the first left-right indicator portion 40A and the second left-right indicator portion 40B.

[0056] [Second embodiment] An index member 200 according to the second embodiment will be described. FIG. 10 is a diagram showing an example of the index member 200 according to the second embodiment. FIG. 11 is a diagram showing the index member 200 as viewed from the Y direction. In this embodiment, the same components as those in the above-described embodiment are denoted by the same reference numerals, and their description will be omitted or simplified. As shown in FIGS. 10 and 11, the index member 200 is attached to two processing devices 10A and 10B. The index member 200 includes a first member 210A and a second member 210B.

[0057] The first member 210A is attached to one of the two processing apparatuses 10A, 10B. In the example shown in FIGS. 10 and 11, the first member 210A is fixed to the bed 11A of the processing apparatus 10A with a bolt BL. The second member 210B is attached to the other of the two processing apparatuses 10A, 10B. In the example shown in FIGS. 10 and 11, the second member 210B is fixed to the bed 11B of the processing apparatus 10B with a bolt BL. The first member 210A and the second member 210B may be fixed by, for example, double-sided tape or the like, in addition to being fixed by the bolt BL.

[0058] The first member 210A includes a first vertical indicator 30A, a first left-right indicator 40A, a first extending portion 50A, and a first front-rear indicator 60A. The first extending portion 50A is provided extending in the front-rear direction perpendicular to the left-right direction in a horizontal plane. The first extending portion 50A is provided extending in the -Z direction from the lower end 51A of the first member 210A. As shown in FIG. 11 , the first front-rear indicator 60A is provided extending in the left-right direction on the first extending portion 50A. The first front-rear indicator 60A indicates a predetermined position in the front-rear direction on the processing device 10A. The first front-rear indicator 60A is a slit (hereinafter referred to as the "first front-rear slit") provided by cutting out a portion of the first extending portion 50A in the left-right direction. The width ΔZ1 of the first front-rear slit indicates the allowable amount of deviation in the relative positions of the two processing devices 10A and 10B in the front-rear direction (hereinafter referred to as "fore-and-aft deviation allowance").

[0059] The second member 210B is arranged next to the first member 21A in the left-right direction and is attached to the processing device 10B so as to be spaced apart from the first member 210A. The second member 21B includes a second up-down indicator 30B, a second left-right indicator 40B, a second extending portion 50B, and a second front-rear indicator 60B. The second extending portion 50B is arranged to extend in the front-rear direction perpendicular to the left-right direction in a horizontal plane. The second extending portion 50B is arranged to extend in the -Z direction from the lower end 51B of the second member 210B. As shown in FIG. 11 , the second left-right indicator 40B is arranged to extend in the left-right direction on the second extending portion 50B. The second left-right indicator 40B indicates a predetermined position in the front-rear direction on the processing device 10B. The second front-rear indicator 60B is a slit (hereinafter referred to as the "second front-rear slit") formed by cutting out the second extending portion 50B in the left-right direction. The width ΔZ2 of the second longitudinal slit indicates the longitudinal misalignment tolerance, which is the tolerance for misalignment of the relative positions of the two processing devices 10A and 10B in the longitudinal direction. Note that, although the width ΔZ1 and the width ΔZ2 are the same, this is not limitative and the width ΔZ1 and the width ΔZ2 may be different.

[0060] Next, a method for checking the relative positional deviation in the front-to-rear direction of the processing devices 10A, 10B using the indicator member 200 will be described. Note that the method for checking the vertical and horizontal deviation of the processing devices 10A, 10B is the same as that for the indicator member 20 of the first embodiment described above, and therefore the description will be omitted. Figure 12 is a diagram for explaining the method for checking the relative positional deviation in the front-to-rear direction of the processing devices 10A, 10B. The first front-to-rear indicator portion 60A and the second front-to-rear indicator portion 60B form a pair as means for indicating the relative position of the processing device 10A and the processing device 10B in the front-to-rear direction.

[0061] When there is no misalignment in the relative positions of the processing apparatus 10A and the processing apparatus 10B in the front-to-rear direction, the first member 210A and the second member 210B are fixed so that the first front-to-rear indicator 60A and the second front-to-rear indicator 60B are aligned in a straight line or approximately in a straight line in the left-to-right direction (see FIG. 11). This state is the intended relative positions of the processing apparatus 10A and the processing apparatus 10B in the front-to-rear direction. Therefore, if there is a misalignment in the front-to-rear direction between the first front-to-rear indicator 60A and the second front-to-rear indicator 60B, that misalignment indicates a misalignment in the relative positions of the processing apparatus 10A and the processing apparatus 10B in the front-to-rear direction.

[0062] Here, at least one of the first longitudinal indicator 60A and the second longitudinal indicator 60B includes a left-right misalignment tolerance. Therefore, if the longitudinal misalignment between the first longitudinal indicator 60A and the second longitudinal indicator 60B exceeds the longitudinal misalignment tolerance, it indicates that the misalignment in the relative position between the processing device 10A and the processing device 10B in the longitudinal direction exceeds the tolerance. On the other hand, if the longitudinal misalignment between the first longitudinal indicator 60A and the second longitudinal indicator 60B does not exceed the longitudinal misalignment tolerance, it indicates that the misalignment in the relative position between the processing device 10A and the processing device 10B in the longitudinal direction is within the tolerance.

[0063] For example, as shown in FIG. 12(A), even if the relative positions of the first and second longitudinal indicators 60A and 60B are misaligned in the front-to-rear direction, as long as portions of the first and second longitudinal indicators 60A and 60B face each other in the left-to-right direction, the misalignment between the first and second longitudinal indicators 60A and 60B does not exceed the allowable misalignment amount. In other words, as long as the front portion (60AL or 60BL) of one of the first and second longitudinal indicators 60A and 60B does not exceed the rear portion (60AH or 60BH) of the other, the misalignment between the first and second longitudinal indicators 60A and 60B does not exceed the allowable misalignment amount. Therefore, the state shown in FIG. 12(A) indicates that the misalignment between the relative positions of the processing apparatus 10A and 10B in the front-to-rear direction is within the allowable range.

[0064] On the other hand, as shown in FIG. 12(B), when the first and second longitudinal indicators 60A and 60B are not all facing each other in the left-right direction, the misalignment between the first and second longitudinal indicators 60A and 60B exceeds the allowable misalignment amount. In other words, the front portions (60AL and 60BL) of the first and second longitudinal indicators 60A and 60B extend beyond the rear portions (60AH and 60BH) of the first and second longitudinal indicators 60A and 60B, respectively, and therefore the misalignment between the first and second longitudinal indicators 60A and 60B exceeds the allowable misalignment amount. Therefore, the state shown in FIG. 12(B) indicates that the misalignment between the relative positions of the processing apparatus 10A and 10B in the front-rear direction exceeds the allowable range.

[0065] If the relative position in the front-to-rear direction between the processing device 10A and the processing device 10B exceeds the allowable amount of front-to-rear misalignment, an adjustment by an operator is required. The operator adjusts the relative position in the front-to-rear direction, for example, by moving the processing device 10A or the processing device 10B. During this adjustment, the operator can easily adjust the relative position in the front-to-rear direction by working while looking at the first front-to-rear indicator 60A and the second front-to-rear indicator 60B.

[0066] The index member 200 may have a connecting piece 22 as shown in FIG. 13 . The connecting piece 22 connects the first member 210A and the second member 210B via a joint portion 23. The connecting piece 22 can be separated from each of the first member 210A and the second member 210B by breaking the joint portion 23. The index member 200 having the connecting piece 22 is attached to a machine tool 1, for example, in pre-shipment work, similar to the index member 20 of the first embodiment. Thereafter, by separating the connecting piece 22, the index member 200 becomes capable of identifying deviations in the relative positions of the two processing apparatuses 10A, 10B in the up-down direction, left-right direction, and front-rear direction, as shown in FIGS. 11 and 12 .

[0067] Thus, according to this embodiment, as in the first embodiment described above, in addition to being able to easily check for any misalignment in the vertical and horizontal directions between the two processing devices 10A and 10B, by providing the first front-to-rear indicator portion 60A and the second front-to-rear indicator portion 60B, the worker can easily check the relative positions of the two processing devices 10A and 10B in the front-to-rear direction.

[0068] In the first and second embodiments described above, the first vertical indicator portion 30A, the second vertical indicator portion 30B, the first left-right indicator portion 40A, the second left-right indicator portion 40B, the first front-rear indicator portion 60A, and the second front-rear indicator portion 60B are slits as indicator portions. However, this is not a limitation. FIG. 14(A) illustrates a diagram using straight lines as indicator portions, and FIG. 14(B) illustrates a diagram using marks as indicator portions. As shown in FIG. 14(A), the indicator portion may be a straight line 300. In this case, the line width ΔL of the straight line 300 indicates the allowable amount of vertical, left-right, or front-rear misalignment. The straight line 300 may be formed by laser processing or may be painted with paint. The straight line 300 may also be an adhesive sticker. It is noted that one of the two indicator portions may be a straight line 300, and the other may be a slit or the like other than the straight line 300.

[0069] 14(B), the indicator portion may be a mark 400 using various shapes or symbols such as a circle or a triangle. In this case, the mark 400 may include a shape indicating the tolerance for misalignment, and as shown in FIG. 14(B), the width ΔL of two shapes (dot-like marks) may indicate the tolerance for misalignment in the up / down, left / right, or front / back directions. Note that one of the two indicator portions may be the mark 400, and the other may be a line 300, a slit, or the like other than the mark 400.

[0070] Although the embodiments have been described above, the technical scope of the present invention is not limited to the above-described embodiments. Furthermore, it will be apparent to those skilled in the art that various modifications and improvements can be made to the above-described embodiments. It is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention. Furthermore, one or more of the requirements described in the above-described embodiments may be omitted. Furthermore, the requirements described in the above-described embodiments may be combined as appropriate. Furthermore, the order in which each step is performed in the embodiments can be arbitrarily determined, as long as the results of a previous step are not used in a subsequent step. Furthermore, even if the operations in the above-described embodiments are described using terms such as "first," "next," and "followed" for convenience, it is not essential that they be performed in this order.

[0071] In the above embodiment, the processing apparatus 10A and the processing apparatus 10B have the same configuration, but the present invention is not limited to this. The processing apparatus 10A and the processing apparatus 10B may have different configurations. [Explanation of symbols]
