Description

  The present invention relates to the position (installation position) of an apparatus (hereinafter referred to as “installation machine processing apparatus”) for processing a machine (hereinafter referred to as “installation machine”) fixed at the installation location. It relates to the technology to adjust.

  When performing processing such as grinding the surface of the bed for an installation machine such as a lathe, an installation machine processing device is installed on or near the installation site of the installation machine, and the installation machine is processed by that. Convenient. When installing such an installation machine processing device at the installation location (site) of the installation machine, the installation machine processing device should be placed in an appropriate horizontal and vertical position (position in the xyz direction) in relation to the installation machine to be processed. The position adjustment for arranging the machine tool and the posture adjustment for setting the installed machining apparatus to an appropriate posture (tilt around three axes) at that position are required. Hereinafter, the position adjustment and the posture adjustment are collectively referred to as “position adjustment”.

  Position adjustment in the height direction (so-called level adjustment) is often particularly important for proper operation of the apparatus. This level adjustment is generally performed by an operator appropriately adjusting a leveling block provided between the apparatus and a floor on which the apparatus is installed. At this time, if the level value of one leveling block is changed, the level values of other leveling blocks need to be readjusted accordingly. Therefore, each leveling block must be finely adjusted repeatedly. Therefore, when the operator manually changes the level value of each leveling block and adjusts the level of the apparatus, it takes time and effort even if it is a skilled worker. In particular, when level adjustment of a large apparatus is performed, since many leveling blocks are used, level adjustment takes a lot of time and labor.

  Therefore, in Patent Document 1, a motor (small high speed reducer built-in type motor) for changing the level value is provided in each leveling block, and a controller for controlling the motor is connected to the motor. There has been proposed a technique of automatically changing the level value of each leveling block by giving an instruction and rotating the motor. By applying this technique, it is possible to change the level value of each leveling block more accurately in a shorter time than when the operator manually changes the level value of each leveling block.

Japanese Patent Laid-Open No. 10-36087

  By the way, in order to appropriately adjust the position, the target level value of each leveling block needs to be set appropriately. In particular, in the case of an installation machine processing device that processes the installation machine to be processed at the place where it is installed, if the relative positional relationship between itself and the installation machine deviates from the specified value, the deviation amount is processed. It is directly related to the error. Therefore, when installing this machine, it is necessary to perform precise position adjustments that take into account the position of the machine to be machined, and set the target level value for each leveling block particularly carefully. There must be.

  In Patent Document 1, the target level value of each leveling block is determined from the difference between the measurement values at a plurality of level measurement points and the design data. However, this method can be used only when the level of a device whose design data is already known is adjusted. In addition, this method cannot be used when precise and flexible position adjustment that takes into account the relative positional relationship between the machine itself and the machine to be machined is required, such as an machine machine.

<1. Installation machining device 8>
The position adjustment system 100 according to the embodiment is a system used for position adjustment of the installation machining apparatus 8. Before describing the position adjustment system 100, the installed machining apparatus 8 will be described with reference to FIG. FIG. 1 is a perspective view of the installation machining apparatus 8. In the drawing, for convenience of explanation, an XYZ orthogonal coordinate system is described in which an extension direction of a rail 91 described later is an X-axis direction and a vertical direction is a Z-axis direction.

  The installation machine processing device 8 is a device that processes the installation machine at a place (site) where the installation machine is installed. Here, as an example, it is assumed that the installation machine that the installation machining apparatus 8 is to process is a lathe 9.

  The lathe 9 includes a long bed 90. Further, the lathe 9 includes a headstock (a base that supports the main shaft) disposed at one end of the bed 90 and a tailstock disposed on the bed so as to face the headstock (both not shown). ), The workpiece is supported between the main shaft and the tailstock so that it can rotate around the main shaft. A rail 91 is laid on the upper surface of the bed 90, and on the rail 91, a tool post for holding a cutting tool (or grinding) and a drive mechanism for moving the tool post on the rail are further provided. Provided (both not shown). The workpiece is cut (by moving between the headstock and the tailstock along the rail while contacting the workpiece supported while being rotated between the spindle and the tailstock. Alternatively, it will be ground). The lathe 9 assumed here is, for example, a large lathe used for surface processing of a huge object having a length exceeding 10 meters such as a rolling roll used for processing steel products. Therefore, the length of the bed 90 and the rail 91 is also more than 10 meters.

  When the lathe 9 is used for a long period of time, the rail 91 formed on the sliding surface is unevenly worn, and the processing accuracy is lowered. For this reason, periodic maintenance is required to keep the rail 91 in an appropriate state. The installation machining apparatus 8 is an apparatus for performing this maintenance at a place (local site) where the lathe 9 is installed. In other words, the installed machining apparatus 8 performs grinding and cutting to make the rail 91 of the lathe 9 that is unevenly worn due to aging and the like horizontal and straight. As described above, according to the aspect in which the lathe 9 is maintained locally, the labor, time, and cost required for maintenance can be greatly reduced as compared with an aspect in which the lathe 9 is maintained by so-called overhaul.

  The installation machining apparatus 8 includes a pair of side frames 81 and 81 laid on the floor 7 on which the bed 90 of the lathe 9 is installed. The pair of side frames 81, 81 are laid on both sides of the bed 90 on the floor 7 on which the bed 90 of the lathe 9 is installed so that each side frame 81 extends along the extending direction of the rail 91 (X-axis direction). Is done. However, each side frame 81 is provided separately from the bed 90 (that is, not in contact with the bed 90). A plurality of position adjusting members 1 are arranged between each side frame 81 and the floor 7 on which it is laid. As will become apparent later, the position of each side frame 81 is precisely adjusted by using the position adjusting member 1 so that the parallelism, the horizontality, etc. with respect to the rail 91 are within a predetermined allowable range.

  A frame rail 811 is formed on the upper surface of each side frame 81. A carriage 82 is placed on the pair of frame rails 811 so as to straddle the frame rails 811. A bearing is disposed between the carriage 82 and the frame rail 811 so that the carriage 82 can move smoothly along the frame rail 811.

  A cart driving mechanism 83 that moves the cart 82 along the frame rail 811 is connected to the cart 82. The cart drive mechanism 83 includes, for example, a motor that is a drive source and a feed mechanism (for example, a rack and pinion mechanism) that converts the rotational motion into a linear motion along the frame rail 811. The cart drive mechanism 83 is electrically connected to a control unit (not shown) of the installation machining apparatus 8, and the control unit gives an instruction to the cart drive mechanism 83, thereby moving the carriage 82 (movement start timing). , Movement end timing, movement speed, etc.).

  The carriage 82 is equipped with a blade 84 and a blade rotation drive mechanism (not shown) that rotates the blade 84 around an axis orthogonal to the tip surface (cutting surface / grinding surface). The blade rotation drive mechanism is electrically connected to the control unit, and the control unit gives an instruction to the blade rotation drive mechanism to thereby rotate the blade 84 (rotation start timing, rotation end timing, rotation speed, etc.). ) To control.

  The carriage 82 is equipped with a blade position changing mechanism 85 that changes the positional relationship between the blade 84 and the rail 91. The cutter position changing mechanism 85 is, for example, a mechanism for changing the Y position of the cutter 84, a mechanism for changing the Z position of the cutter 84, and the posture of the cutter 84 (for example, centering on the rotation axis on the shaft portion of the cutter 84). And a mechanism for changing the rotational position. The blade position changing mechanism 85 is electrically connected to the control unit, and the control unit controls the position of the blade 84 by giving an instruction to the blade position changing mechanism 85.

  As described above, the installed machining apparatus 8 performs grinding / cutting to make the rail 91 of the lathe 9 that is unevenly worn due to aging and the like horizontal and straight. For example, the flow of processing in which the installed machining apparatus 8 performs the processing is as follows.

  That is, first, the control unit of the installed machining apparatus 8 adjusts the position of the blade 84 relative to the rail 91 by giving an instruction to the blade position changing mechanism 85. Specifically, the blade 84 is arranged in a state where the tip thereof is in contact with the surface of the rail 91. That is, the blade 84 has a height such that the tip thereof is parallel to the surface of the rail 91, the Y position coincides with the Y position of the rail 91, and the tip contacts the surface of the rail 91. ,Deploy.

  Thereafter, when an input of a machining start instruction from the operator is received, the control unit controls the carriage driving mechanism 83 to start the movement of the carriage 82 (reciprocating movement along the frame rail 811), and the blade rotation driving mechanism. Is controlled to start the rotation of the blade 84. Thereby, the processing of the surface of the rail 91 by the blade 84 proceeds. As will become apparent later, the frame rail 811 is strictly aligned so as to extend parallel and straight to the rail 91. Therefore, by machining the surface of the rail 91 with the blade 84 that reciprocates while being guided by the frame rail 811, the surface of the rail 91 is flattened, and the extending direction of the rail 91 is horizontal and straight. Thus, it can be processed with high accuracy. When the preset machining time has elapsed, the control unit stops the carriage 82 at a predetermined position. This completes the processing process.

<2. Configuration of Position Adjustment System 100>
The configuration of the position adjustment system 100 will be described with reference to FIG. FIG. 2 is a diagram illustrating a configuration of the position adjustment system 100.

  The position adjustment system 100 includes a plurality of position adjustment members 1, a position measurement device 2, and a control device 3.

<Position adjustment member 1>
The position adjustment member 1 is a member that adjusts the position (specifically, the Y position and the Z position) of the installation machining device 8 (specifically, the side frame 81 that is a member included in the installation machining device 8). A plurality of the frames are disposed between the side frame 81 and the floor 7 on which the side frame 81 is installed. However, each of the plurality of position adjusting members 1 is disposed at a different location.

  As described above, the side frame 81 is a long member, and its extending direction is indicated by the X axis in the drawing. The plurality of position adjusting members 1 are arranged at intervals along the extending direction (X direction) of the side frame 81. However, here, two position adjusting members 1 are paired, and two paired position adjusting members 1 (hereinafter also referred to as “position adjusting member pair 10”) are arranged at the same X position. The Further, in the position adjustment member pair 10, the pair of position adjustment members 1 are disposed to face each other so that inclined surfaces 120 (described later) of the inclined blocks 12 face each other with the side frame 81 interposed therebetween.

  Here, the configuration of the position adjusting member 1 and the mode of adjusting the position of the side frame 81 using the position adjusting member pair 10 will be specifically described with reference to FIGS. 3 and 4. FIG. 3 is a diagram for explaining a mode in which the position adjustment of the side frame 81 in the Z direction is performed using the position adjustment member pair 10. FIG. 4 is a diagram for explaining a mode in which the position adjustment of the side frame 81 in the Y direction is performed using the position adjustment member pair 10.

  The position adjusting member 1 includes an inclined block 12 disposed on a base 11 disposed on the floor 7 and a fixed block 13 disposed thereon. The fixed block 13 is fixed to the side frame 81 via the support plate 14. The upper surface of the inclined block 12 is an inclined surface (inclined surface) 120. The lower surface of the fixed block 13 is a surface 130 that is inclined at the same angle as the inclined surface 120. And these surfaces 120 and 130 contact | abut so that sliding is possible along an inclination direction.

  The inclined block 12 is connected to a drive unit 15 that moves the inclined block 12 along a horizontal axis located in the same vertical plane as the axis (inclined axis) along the inclined direction of the inclined surface 120. The drive unit 15 includes, for example, a motor and a ball screw mechanism for converting the rotational force of the motor into a linear motion along the horizontal axis.

  In each position adjusting member 1, a horizontal axis (hereinafter also referred to as “movable axis”) located in the same vertical plane as the tilt axis of the tilted surface 120 is a direction perpendicular to the extending direction of the side frame 81. ). As shown in FIG. 3, in the position adjustment member pair 10 arranged at a certain X position, the pair of inclined blocks 12 opposed to each other by each drive unit 15 are opposite to each other (that is, the other inclined block). 12), the Z position h of the portion of the X position in the side frame 81 is changed (moved) by a change amount ΔZ corresponding to the movement amount (Z direction adjustment). . That is, when the pair of inclined blocks 12 move in a direction approaching each other as shown in the drawing (that is, when each inclined block 12 moves in the direction from the higher side of the inclined surface 120 toward the lower side). The Z position becomes higher. Conversely, when the pair of inclined blocks 12 move away from each other (that is, when each inclined block 12 moves in the direction from the lower side of the inclined surface 120 toward the higher side), the Z The position is lowered.

  As shown in FIG. 4, in the position adjustment member pair 10 arranged at a certain X position, when the pair of inclined blocks 12 arranged opposite to each other are moved in the same direction by each drive unit 15, The Y position of the portion of the X position in the side frame 81 is changed (moved) by the same change amount ΔY as the movement amount (Y direction adjustment). That is, as shown in the figure, when the pair of inclined blocks 12 moves in the −Y direction, the Y position of the side frame 81 shifts in the −Y direction. Conversely, when the pair of inclined blocks 12 moves in the + Y direction, the Y position of the side frame 81 shifts in the + Y direction.

  Thus, the side frame 81 can change the Z position and the Y position at the X position where the position adjustment member pair 10 is disposed. The X position at which the position adjustment member pair 10 in the side frame 81 is disposed is hereinafter also referred to as “change point”. The smaller the interval between the change points (that is, the greater the number of position adjustment member pairs 10), the higher the accuracy of position adjustment of the side frame 81. For example, when the entire length of the side frame 81 is about 14 m, the interval between the change points is preferably about 1 m.

<Position measuring device 2>
Refer to FIG. 2 again. The position measurement device 2 is a device that measures the position of a measurement object and acquires position information (one-dimensional, two-dimensional, or three-dimensional coordinate information) of each of a plurality of points in the measurement object. Preferably, the position measurement device 2 is configured by a three-dimensional measurement device (particularly preferably, a laser-type three-dimensional measurement device) that acquires three-dimensional position information of each point. The position measuring device 2 is connected to the control device 3, performs three-dimensional measurement on the measurement object in accordance with an instruction from the control device 3, and transmits the obtained position measurement information to the control device 3.

<Control device 3>
As described above, the control device 3 is connected to the position measurement device 2, and the position measurement information acquired by the position measurement device 2 by measuring the position of the measurement object (for example, three-dimensional measurement) is used as the position measurement device 2. Get from. The control device 3 is connected to the drive unit 15 of each position adjusting member 1 via a PLC 30 (also called a programmable logic controller, also called a sequencer), and controls each drive unit 15.

  The actual state of the control device 3 is, for example, a computer. Specifically, as shown in FIG. 5, the control device 3 includes a central processing unit (CPU) 31, a memory 32, a monitor 33 including an LCD (Liquid Crystal Display), a keyboard, a mouse, and the like. An input unit 34, a storage unit 35, and an interface (I / F) 36 for managing connection with a network such as a LAN (Local Area Network) with an external device are connected to each other. Yes. The memory 32 is configured by a volatile storage device such as a RAM (Random Access Memory), for example. The storage unit 35 includes, for example, ROM (Read only Memory), flash memory, EPROM (Erasable Programmable ROM), EEPROM (registered trademark) (Electrically EPROM), HDD (Hard Disc Drive), SSD (Solid State Drive), and the like. The non-volatile storage device. In addition to an OS (Operating System) that controls the overall operation of the control device 3, the storage unit 35 stores a program 300 for causing the control device 3 to function as a control device of the position adjustment system 100.

  The program 300 includes a preliminary adjustment unit 301, a measurement instruction unit 302, a determination unit 303, a change amount calculation unit 304, and an adjustment instruction unit 305. Each of these is a functional unit realized by software by the CPU 31 reading the program 300 into the memory 32 and executing it. These functional units 301 to 305 may be realized by using dedicated hardware, but may be realized by using a general-purpose computer as a hardware resource and executing dedicated processing software installed in the computer. Is common.

<3. Operation of Position Adjustment System 100>
A mode in which the position adjustment system 100 adjusts the position of the installed machining apparatus 8 will be described with reference to FIG. 6 in addition to FIGS. FIG. 6 is a diagram illustrating a flow of processing performed by the position adjustment system 100.

  Step S1: First, a pair of side frames 81, 81 are temporarily placed on both sides of the bed 90 on the floor 7 on which the lathe 9 (specifically, the bed 90 of the lathe 9) is installed. At this time, a plurality of position adjusting members 1 are arranged with a space between the floor 7 and each side frame 81. However, as described above, two position adjusting members 1 are paired, and two paired position adjusting members 1 (position adjusting member pair 10) are arranged opposite to each other with the side frame 81 interposed therebetween at the same X position. .

  Step S2: Next, preliminary adjustment of the lathe 9 is performed. Specifically, for example, the preliminary adjustment unit 301 includes a center (center viewed from the horizontal direction) of a spindle (not shown) disposed on the bed 90 and a center (horizontal view) of a tailstock (not shown). The position measuring device 2 is measured to determine the position of an imaginary line (axial line) connecting the centers. Then, the height of the bed 90 is adjusted so that the axial center line is orthogonal to the vertical axis (that is, extends in a horizontal plane). This adjustment can be performed, for example, by adjusting a plurality of leveling blocks (not shown) provided at intervals on the legs of the bed 90. In some cases, the step S2 may be omitted.

  Step S3: Subsequently, the measurement instruction unit 302 causes the position measuring device 2 to measure the position of the lathe 9 (specifically, the rail 91 of the lathe 9). Specifically, for example, position measurement information (here, three-dimensional coordinate information) of a plurality of points on the rail 91 is acquired. The acquired position measurement information is transmitted from the position measurement device 2 to the control device 3 and written in a file stored in the storage unit 35 of the control device 3.

  Step S4: Subsequently, the measurement instruction unit 302 causes the position measurement device 2 to measure the position of each side frame 81. Specifically, for example, position measurement information (here, three-dimensional coordinate information) of a plurality of points on each side frame 81 is acquired. The acquired position measurement information is transmitted from the position measurement device 2 to the control device 3 and written in a file stored in the storage unit 35 of the control device 3.

  Step S5: Subsequently, the determination unit 303 determines the Y direction of each side frame 81 based on the position measurement information of the rail 91 obtained in Step S3 and the position measurement information of each side frame 81 obtained in Step S4. It is determined whether or not position adjustment is necessary. Specifically, the determination unit 303 calculates, for example, the parallelism in the Y direction between the rail 91 and each side frame 81 based on the position measurement information of the rail 91 and the position measurement information of each side frame 81, If the calculated parallelism exceeds a predetermined allowable range, it is determined that position adjustment in the Y direction is necessary (YES in step S5).

Step S6: When it is determined that the position adjustment of the side frame 81 in the Y direction is necessary, the change amount calculation unit 304 calculates the change amount in the Y direction to be changed by each position adjustment member pair 10.
Specifically, for example, the change amount calculation unit 304 first determines an ideal side that extends straight in parallel along the Y direction based on the position measurement information of the rail 91 obtained in step S3. A frame 81 is defined. However, when the rail 91 is unevenly worn, the ideal position of the rail 91 without uneven wear is calculated based on the position measurement information of the rail 91 in consideration of this, and the ideal rail An ideal side frame 81 that extends straight along the Y direction with respect to 91 is defined. When the ideal side frame 81 is defined, the Y position (target Y position) of each change point in the ideal side frame 81 is specified. Then, the deviation amount from the target Y position of the Y position of each change point in the actual side frame 81 (that is, the Y position of each change point specified from the position measurement information obtained in step S4) is calculated, The shift amount is set as a change amount in the Y direction of the change point.

  Step S7: Subsequently, the adjustment instruction unit 305 sends the Y of the side frame 81 at each change point to each position adjustment member pair 10 (specifically, the drive unit 15 of each position adjustment member 1) via the PLC 30. An instruction is given to change the position by the change amount calculated in step S6. When receiving the instruction, the position adjusting member pairs 10 change the Y position by the instructed change amount all at once (or sequentially). As a result, the position of the side frame 81 in the Y direction is adjusted.

  When the process of step S7 is completed, the process returns to step S3 again. That is, the measurement instruction unit 302 causes the position measurement device 2 to measure the position of the rail 91 (step S3) and measure the position of each side frame 81 (step S4). Then, the determination unit 303 adjusts the position of each side frame 81 in the Y direction based on the position measurement information on the rail 91 obtained in step S3 and the position measurement information on each side frame 81 obtained in step S4. The necessity is determined (step S5). If the process of step S7 is appropriately performed, the parallelism in the Y direction between the rail 91 and each side frame 81 is within a predetermined allowable range. In this case, it is determined that position adjustment in the Y direction is unnecessary (NO in step S5).

  Step S8: If it is determined that the position adjustment of the side frame 81 in the Y direction is not necessary, the determination unit 303 continues with the position measurement information of the rail 91 obtained in step S3 and each of the pieces obtained in step S4. Based on the position measurement information of the side frames 81, it is determined whether or not it is necessary to adjust the position of each side frame 81 in the Z direction. Specifically, the determination unit 303 calculates, for example, the parallelism in the Z direction between the rail 91 and each side frame 81 based on the position measurement information of the rail 91 and the position measurement information of each side frame 81, If the calculated parallelism exceeds a predetermined allowable range, it is determined that position adjustment in the Z direction is necessary (YES in step S8).

Step S9: When it is determined that the position adjustment of the side frame 81 in the Z direction is necessary, the change amount calculation unit 304 calculates the change amount in the Z direction to be changed by each position adjustment member pair 10.
Specifically, for example, similarly to step S6 described above, the change amount calculation unit 304 first extends straight in parallel with the Z direction in accordance with the position measurement information of the rail 91 obtained in step S3. Such an ideal side frame 81 is defined, and the Z position (target Z position) of each change point in the ideal side frame 81 is specified. Then, the deviation amount from the target Z position of the Z position of each change point in the actual side frame 81 (that is, the Z position of each change point specified from the position measurement information obtained in step S4) is calculated, The shift amount is set as the change amount in the Z direction of the change point.

  Step S10: Subsequently, the adjustment instruction unit 305 changes the Z position of the side frame 81 at each change point by the change amount calculated in Step S9 to each position adjustment member pair 10 via the PLC 30. Give instructions. When receiving the instruction, the position adjustment member pairs 10 change the Z position by the instructed change amount all at once (or sequentially). As a result, the position of the side frame 81 in the Z direction is adjusted.

  When the process of step S10 is completed, the process returns to step S3 again. That is, the measurement instruction unit 302 causes the position measurement device 2 to measure the position of the rail 91 (step S3) and measure the position of each side frame 81 (step S4). Then, the determination unit 303 adjusts the position of each side frame 81 in the Y direction based on the position measurement information on the rail 91 obtained in step S3 and the position measurement information on each side frame 81 obtained in step S4. Necessity is determined (step S5), and if a negative determination is obtained, it is further determined whether it is necessary to adjust the position of each side frame 81 in the Z direction (step S8). If the process of step S9 is appropriately performed, the parallelism in the Z direction between the rail 91 and each side frame 81 is within a predetermined allowable range. In this case, it is determined that position adjustment in the Z direction is unnecessary (NO in step S8).

  Step S11: When it is determined that the position adjustment in the Z direction of each side frame 81 is unnecessary (that is, when it is determined that neither the position adjustment in the Y direction nor the Z direction is required), each side frame 81 is fixed to the floor 7 with a bolt or the like so as not to move (main fixing). Thus, a series of processes related to the position adjustment of the installed machining apparatus 8 is completed.

<4. First Modification>
In the above embodiment, two position adjusting members 1 are paired, and two paired position adjusting members 1 (position adjusting member pair 10) are at the same X position (each change point). Although it has been arranged, as shown in FIG. 7, there may be one position adjusting member 1 arranged at each change point. That is, the plurality of position adjusting members 1 are arranged at intervals on one side of each side frame 81 (for example, the -Y side of the -Y side frame 81 and the + Y side of the + Y side frame 81). May be.

  Also in this modified example, each position adjusting member 1 is arranged such that the movable shaft is along the Y-axis (that is, the direction orthogonal to the extending direction of the side frame 81). As shown in FIG. 7, in the position adjustment member 1 arranged at a certain X position, when the tilt block 12 is moved by the drive unit 15, the change in the side frame 81 by the change amount ΔZ corresponding to the movement amount. The Z position h at the X position is changed (moved) (Z direction adjustment). That is, when the inclined block 12 moves in the direction from the higher side of the inclined surface 120 toward the lower side as shown in the drawing, the Z position becomes higher. Conversely, when the inclined block 12 moves in the direction from the lower side of the inclined surface 120 toward the higher side, the Z position becomes lower.

<5. Second Modification>
In the above embodiment, the position adjustment member pair 10 is disposed at each change point, but the position adjustment unit 10a may be disposed at each change point. That is, the plurality of position adjustment units 10a are arranged on one side of each side frame 81 (for example, on the −Y side of the −Y side frame 81 and the + Y side of the + Y side frame 81), or on each side You may arrange | position at intervals along the centerline of the flame | frame 81. FIG. The configuration of the position adjustment unit 10a according to this modification will be described with reference to FIGS. FIG. 8 is a diagram for explaining an aspect in which the position adjustment of the side frame 81 in the Z direction is performed using the position adjustment unit 10a. FIG. 9 is a diagram for describing a mode in which the position adjustment of the side frame 81 in the Y direction is performed using the position adjustment unit 10a. In the following description, the same elements as those in the above embodiment are denoted by the same reference numerals and the description thereof is omitted.

  The position adjustment unit 10 a includes a movable box 16 disposed on the base 11 disposed on the floor 7. The position adjusting member 1 described above is disposed in the movable box 16. However, the movable box 16 has a size sufficiently larger than the movable range along the movable axis of the inclined block 12 of the position adjusting member 1, and the inclined block 12 is located at an arbitrary position within the movable range within the movable box 16. Can be moved to.

  The movable box drive unit for moving the movable box 16 forward and backward in a horizontal direction orthogonal to the movable axis of the inclined block 12 disposed thereon (that is, a horizontal direction orthogonal to the inclined direction of the inclined surface 120). 17 are connected. The movable box drive unit 17 includes, for example, a motor and a ball screw mechanism for converting the rotational force of the motor into a linear motion along a horizontal direction orthogonal to the movable shaft. That is, here, a mechanism for moving the position adjusting member 1 in the horizontal direction perpendicular to the movable axis is realized by the cooperation of the movable box 16 and the movable box drive unit 17.

  In this modification, each position adjustment unit 10a is arranged such that the movable shaft of the position adjustment member 1 provided in the position adjustment unit 10a is along the X axis (that is, the extending direction of the side frame 81). In other words, in each position adjustment unit 10a, the moving direction of the movable box 16 included in the position adjustment unit 10a (that is, the horizontal direction perpendicular to the inclination direction of the inclined surface 120 of each position adjustment member 1) is the Y axis (that is, the extension of the side frame 81). It is arrange | positioned along the direction orthogonal to a present direction.

  As shown in FIG. 8, in the position adjustment unit 10a arranged at a certain X position, when the inclined block 12 of the position adjustment member 1 is moved by the drive unit 15, only the change amount ΔZ corresponding to the movement amount is obtained. The Z position h at the X position in the side frame 81 is changed (moved) (Z direction adjustment). That is, as shown in the drawing, when the inclined block 12 moves in the direction from the higher side of the inclined surface 120 toward the lower side, the Z position becomes higher. Conversely, when the inclined block 12 moves in the direction from the lower side of the inclined surface 120 toward the higher side, the Z position becomes lower.

  As shown in FIG. 9, in the position adjustment unit 10a arranged at a certain X position, when the movable box 16 is moved by the movable box drive unit 17, the position adjustment member is changed by the same change amount as the movement amount. 1 is changed, whereby the Y position of the side frame 81 supported by the position adjustment member 1 (that is, the portion of the X position in the side frame 81) is changed (moved) (Y direction). Adjustment). That is, as illustrated, when the movable box 16 moves in the −Y direction, the Y position of the side frame 81 shifts in the −Y direction. Conversely, when the movable box 16 moves in the + Y direction, the Y position of the side frame 81 shifts in the + Y direction.

  In this way, the position adjustment unit 10a can change the Z position and the Y position of the side frame 81 at the X position where it is disposed.
