Description

  The present invention relates to a technique for scuffing a machine (hereinafter, referred to as “installation machine”) fixed at an installation location.

  In general, in a sliding surface such as a bed surface of a lathe, if the flatness is increased, the lubricating oil does not enter between the sliding surfaces, and there arises a problem of sticking or seizing. Therefore, it is necessary to perform a process (so-called “scraping process”) for providing a minute recess that becomes an oil reservoir on such a sliding surface.

  Conventionally, scraping is often performed manually by an operator (that is, when the worker cuts a target surface to be scraped with a scraping tool). However, this is a task that requires skill, and was a heavy labor.

  Therefore, an apparatus that automatically performs scraping has been proposed. For example, Patent Literatures 1 to 3 include a base, a slide rail laid on the side of the base, a moving device movably disposed along the slide rail, and a cutting tool mounted thereon. A scraped surface forming apparatus is disclosed. In this apparatus, an object (work) to be scraped is placed on a base, and the workpiece is scraped while the moving device reciprocates along the slide rail. However, this apparatus cannot cope with scraping of a large object (for example, a large lathe) that cannot be placed on the base.

  On the other hand, in Patent Document 4, a carriage on which an electromotion caulking tool is installed is placed on a surface to be scraped (specifically, a bed of a machine tool), and the carriage is placed on the bed. A technique has been proposed in which the sliding surface of the bed is scraped by an electromotion beveling tool while reciprocating along the longitudinal direction. According to this technology, since the object can be scraped at the place where the object is installed, the size of the object is not limited, and the large object as described above can be used. Can also be used for saddle processing.

JP-A-8-187620 Japanese Patent Laid-Open No. 7-246515 Japanese Unexamined Patent Publication No. 7-246516 Japanese Patent Laid-Open No. 10-151522

  However, in Patent Document 4, since the carriage on which the electric motion pegging tool is installed is placed on the bed that is the object to be processed, when the upper surface of the bed has inclination or undulation, There is a possibility that inconveniences such that the recesses formed by the saddle processing become locally deep (or shallow) and the interval between the recesses becomes locally long (or short) may occur. In addition, if the upper surface of the bed has an inclination or undulation, the carriage cannot smoothly move back and forth, and there is a possibility that the time required to complete the scraping process may be increased. Thus, with the configuration of Patent Document 4, it has been difficult to perform screeding with sufficient accuracy and speed.

  The problem to be solved by the present invention is to provide a technique that enables the installation machine to perform the bending process with sufficient accuracy and speed when the installation machine is installed at the place (site) where the installation machine is installed. .

The present invention made to solve the above problems
A scraping device for scraping a target surface in an installation machine,

A scraping portion mounted on the carriage,
A control unit that causes the scraping processing unit to perform scoring of the target surface while moving the carriage along the pair of side rails;
Is provided.

  In this configuration, the control unit causes the scoring unit mounted on the cart to perform scoring of the target surface while moving the cart along the pair of side rails. Here, the pair of side rails is not laid on the installation machine, but is laid on the floor where the installation machine is placed. Regardless of the car, you can drive straight. Accordingly, the scraping portion can accurately form the concave portions at the predetermined positions at the predetermined intervals. Moreover, since the carriage is secured so that it can move smoothly, the speed of the carriage can be set to a relatively high speed, and the time required for scraping can be reduced. Thus, according to this configuration, scoring of the target surface in the installation machine can be performed with sufficient accuracy and speed.

The present invention is also directed to a method for scraping a target surface in an installation machine. This scraping method is
Laying a pair of side rails at positions on both sides of the installation machine on the floor where the installation machine is disposed;
A step of installing a carriage equipped with a scraping portion on the pair of side rails so as to straddle the installation machine;
Causing the scraping portion to scrape the target surface while moving the carriage along the pair of side rails on the pair of side rails;
Is provided.

  According to the present invention, the pair of side rails causes the scraping unit to perform scoring of the target surface in the installation machine while moving the carriage mounted with the scraping unit along the pair of side rails. However, it is not laid on the installation machine, but is laid on the floor on which the installation machine is arranged, so that the target surface can be scraped with sufficient accuracy and speed.

The overall configuration of the scoring apparatus 100 will be described with reference to FIGS. FIG. 1 is a perspective view showing the overall configuration of the scoring apparatus 100. FIG. 2 is a front view of the scraping apparatus 100. FIG. 3 is a cross-sectional view of the scraping device 100 as viewed from the direction of the arrow AA in FIG. In FIG. 1 to FIG. 3, each element is schematically shown for convenience of explanation, and some elements are not shown for easy understanding of the drawings.

The scraping device 100 is a device that scrapes and processes the installation machine at a place (site) where the installation machine to be processed is installed. Here, as an example, it is assumed that the installation machine is a lathe 9, and the scraping device 100 performs scraping of the rail 91 of the lathe 9 (that is, the rail 91 formed on the upper surface of the bed 90 of the lathe 9). The case where it performs is demonstrated.
In the figure, for convenience of explanation, an XYZ orthogonal coordinate system in which the extending direction of the rail 91 is the X-axis direction and the vertical direction is the Z-axis direction is shown.

  The dressing apparatus 100 includes a pair of side rails 1a and 1b laid on a floor 101 on which a bed 90 of a lathe 9 is installed. Further, the scraping device 100 includes a carriage 2 installed on a pair of side rails 1a and 1b so as to straddle a bed 90, and a carriage drive mechanism 3 that moves the carriage 2 along the pair of side rails 1a and 1b. And comprising. Further, the scraping device 100 includes a scraping unit 4 mounted on the carriage 2 and a position changing mechanism 5 that changes the positional relationship between the scraping unit 4 and the rail 91. Moreover, the scraping apparatus 100 includes a control unit 6 that is electrically connected to each unit included in the scraping processing apparatus 100 and controls each unit. Hereinafter, each element with which the scraping apparatus 100 is provided is demonstrated concretely.

<I. Side rail 1a, 1b>
The pair of side rails 1a and 1b are arranged on both sides of the bed 90 on the floor 101 on which the bed 90 of the lathe 9 is installed so that the side rails 1a and 1b are along the extending direction (X-axis direction) of the rail 91. Laid. However, the side rails 1a and 1b are provided separately from the bed 90 (that is, not in contact with the bed 90).
Of the pair of side rails 1 a and 1 b, the one laid on the side of the bed 90 on the −Y side is also referred to as “first side rail 1 a” hereinafter. Further, what is laid on the opposite side to the first side rail 1a (that is, the side on the + Y side of the bed 90) across the bed 90 is hereinafter also referred to as “second side rail 1b”.
As will become apparent later, the first side rail 1a and the second side rail 1b are precisely adjusted so that their parallelism, parallelism with respect to the rail 91, and horizontality are within predetermined tolerances. The position is adjusted.

Rail portions 11 are formed on the upper surfaces of the side rails 1a and 1b. The carriage 2 is placed on the pair of rail portions 11 so as to straddle the rail portions 11. A bearing 12 is arranged between the carriage 2 and the rail portion 11 so that the carriage 2 can move smoothly along the rail portion 11.
In addition, since the carriage drive mechanism 3 is placed on one side (−Y side in the illustrated example) of the carriage 2, a side rail that supports the one side of the carriage 2 (in the illustrated example, the first side rail). 1a) is subjected to a larger load than the side rail supporting the other side (second side rail 1b in the illustrated example). That is, the first side rail 1a needs higher rigidity than the second side rail 1b. For this reason, the 1st side rail 1a is formed thicker than the 2nd side rail 1b.

  One end of the regulating member 13 is fixed to the side surface (side surface facing the bed 90) of each side rail 1a, 1b. The regulating member 13 extends substantially horizontally, and the other end abuts on the side surface of the bed 90. Thereby, the bed 90 and the side rails 1a and 1b are relatively fixed. That is, the restricting member 13 is a member for restricting the relative positional relationship between the side rails 1 a and 1 b and the bed 90. By providing the restricting member 13, side shake of the side rails 1 a and 1 b caused by vibration of the bed 90 during processing is suppressed.

  A member (height adjusting member) 14 for adjusting the height of the side rails 1a and 1b is disposed between the side rails 1a and 1b and the floor 101 on which the side rails 1a and 1b are laid. The height adjusting member 14 is constituted by, for example, a leveling block. A plurality of height adjusting members 14 are arranged at intervals along the extending direction (X direction) of the side rails 1a and 1b. Therefore, even when the floor 101 on which the side rails 1a and 1b are installed has an inclination or the like, the rail portion 11 formed on the upper surface of the side rails 1a and 1b by individually adjusting the height adjusting members 14. Can be placed in a horizontal plane.

  As shown in FIG. 1, each side rail 1a, 1b is connected to a plurality of frame pieces 15, 15,... Arranged in a line along the extending direction (X direction in the figure). It consists of. Each frame piece 15 has flanges formed at both ends thereof, and is connected and fixed using a connecting member while being positioned with the flanges of adjacent frame pieces 15 in contact with each other. The connecting member is preferably a member that can adjust the relative position of each frame piece 15. Specifically, the connecting member can be composed of, for example, a key, a positioning bolt, and the like.

<Ii. Dolly 2 and Dolly Drive Mechanism 3>
The carriage 2 is installed on the side rails 1 a and 1 b (specifically, the rail portion 11) so as to straddle the bed 90 of the lathe 9. As described above, the bearing 12 is sandwiched between each rail portion 11 and the carriage 2 so that the carriage 2 can move smoothly along the side rails 1a and 1b.
Further, the carriage 2 is moved on the side rails 1a and 1b (specifically, the rail portion 11) along the side rails 1a and 1b (along the X axis). Is installed. The cart drive mechanism 3 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 rail portion 11.
The cart drive mechanism 3 is electrically connected to the control unit 6, and the control unit 6 gives an instruction to the cart drive mechanism 3 to move the cart 2 in the movement mode (movement start timing, movement end timing, movement speed, Etc.).

<Iii. Kisage processing part 4>
The carriage 2 is equipped with a scraping portion 4 for scraping. Specifically, the scraping portion 4 includes a support body 41, a support plate 42 disposed at the lower end thereof, and another support plate 43 connected to the support plate 42 via a hinge portion 44. . A cutting tool (generally also referred to as a scraper) 40 is indirectly supported by the lower support plate 43.

  Each of the pair of support plates 42 and 43 is a long flat plate extending in the Y direction, and is connected to one end in the long direction via a hinge portion 44 and the other end via an adjustment rod 45. It is connected. One end of the adjusting rod 45 is connected to one support plate 43 via a hinge portion, and the other end is inserted through a through hole formed in the other support plate 42. The adjustment rod 45 is connected to a drive portion 46 that moves the adjustment rod 45 forward and backward along the extending direction thereof, and the drive portion 46 moves the adjustment rod 45 forward and backward to move the lower support plate 43 (and thus, The blade 40) swings around the hinge portion 44.

  A guide rail 431 extending along the Y direction is laid on the lower surface of the lower support plate 43, and a moving body 47 that reciprocates along the guide rail 431 is placed on the guide rail 431. It is arranged. The cutter 40 is connected to the moving body 47, and the cutter 40 reciprocates along the guide rail 431 when the movable body 47 reciprocates along the guide rail 431.

  In the scoring unit 4 having such a configuration, the blade 40 is driven by the driving unit 46 in a state of being in contact with a target surface (here, the surface of the rail 91) to be scoring. A concave portion is formed on the target surface by being moved along the guide rail 431 while being swung and being driven by the moving body 47. However, the drive unit 46 and the moving body 47 are electrically connected to the control unit 6, and the control unit 6 cuts the blade 40 by giving an instruction to the drive unit 46 and the moving body 47. Aspects (size, depth of recessed portions to be formed, formation interval of recessed portions, pushing amount of the blade 40, etc.) are controlled.

<Iv. Position change mechanism 5>
The carriage 2 is equipped with a position changing mechanism 5 that changes the position of the scraping portion 4 (that is, changes the positional relationship between the scraping portion 4 and the rail 91). That is, a guide rail (Y guide rail) 51 extending along a direction (Y direction) orthogonal to the side rails 1 a and 1 b is laid on the front surface (the surface on the −X side) of the carriage 2. A first base plate 52 is arranged on the Y guide rail 51 so as to be movable along the Y guide rail 51. The carriage 2 is connected to a Y drive mechanism 53 that moves the first base plate 52 along the Y guide rail 51 (along the Y axis). The scraping portion 4 is indirectly supported by the first base plate 52, and the Y position of the scraping portion 4 can be changed by changing the Y position of the first base plate 52.

  A guide rail (Z guide rail) 54 extending along the vertical direction (Z direction) is laid on the front surface (the −X side surface) of the first base plate 52. A second base plate 55 is disposed on the Z guide rail 54 so as to be movable along the Z guide rail 54. The second base plate 55 is connected to a Z drive mechanism 56 that moves the second base plate 55 along the Z guide rail 54 (along the Z axis). The scraping portion 4 is indirectly supported by the second base plate 55, and the height of the scraping portion 4 is changed by changing the height (Z position) of the second base plate 55. it can.

  On the front surface (+ X side surface) of the second base plate 55, a ring-shaped guide rail (R guide rail) 57 is laid. A rotation shaft portion 58 is disposed at the center of the R guide rail 57 in the second base plate 55, and the support body 41 of the scraping processing portion 4 is supported on the rotation shaft portion 58. In addition, an R drive mechanism (not shown) for rotating the rotation shaft portion 58 is connected to the rotation shaft portion 58. When the R drive mechanism rotates the rotation shaft portion 58, the support body 41 rotates around the rotation shaft portion 58 while being guided by the R guide rail 57. By changing the posture (rotation position) of the support body 41, the posture of the scraping processing unit 4 can be changed.

  The Y drive mechanism 53, the Z drive mechanism 56, the R drive mechanism, and the drive unit 46 are electrically connected to the control unit 6. The control unit 6 controls the position and posture of the scraping processing unit 4 by giving instructions to the Y drive mechanism 53, the Z drive mechanism 56, and the R drive mechanism.

<2. Installation of Kisage Processing Device 100>
A mode in which the scraping device 100 is installed at a place (local site) where the lathe 9 is installed will be described with reference to FIG. 4 in addition to FIGS. FIG. 4 is a diagram showing a flow of work for installing the scraping device 100 on site.

  Step S1: First, a pair of side rails 1a and 1b is temporarily placed on both sides of the bed 90 on the floor 101 on which the lathe 9 (specifically, the bed 90 of the lathe 9) is installed. Specifically, a plurality of frame pieces 15, 15,... For constituting the first side rail 1 a are arranged on one side of the bed 90 and combined (specifically, adjacent frame pieces 15. , 15 are brought into close contact with each other and connected with a connecting member). Further, a plurality of frame pieces 15, 15,... For constituting the second side rail 1 b are arranged on the other side of the bed 90 and combined.

  Step S2: Next, the state of a reference surface (for example, the upper surface of the bed 90) for leveling the bed 90 is measured using a three-dimensional laser measuring device (not shown). When the wear of the reference surface is severe, the accuracy cannot be ensured even if the bed 90 is leveled based on the reference surface. Therefore, first, based on the state of the reference surface measured here, it is determined whether or not the bed 90 can be leveled based on the reference surface. Specifically, for example, it is determined whether or not the measured flatness of the reference surface is within a predetermined allowable range. If the flatness is not within the allowable range, the bed 90 based on the reference surface is determined. Judge that leveling is not possible. This determination may be performed by the control unit 6 of the scoring apparatus 100 or by an operator.

  Step S3: If it is determined in step S2 that the bed 90 can be leveled based on the reference plane, the bed 90 is leveled based on the reference plane. Specifically, for example, the height of the bed 90 is adjusted so that the reference surface extends in the horizontal plane based on the measurement value obtained in step S2. This adjustment can be performed, for example, by adjusting a plurality of leveling blocks provided at intervals on the legs of the bed 90.

  Step S4: If it is determined in step S2 that the bed 90 cannot be leveled based on the reference plane, the bed 90 is leveled without using the reference plane. Specifically, for example, the center (not shown) of the spindle (not shown) disposed on the bed 90 and the center of the tailstock (not shown) (the center seen from the horizontal) Is measured using the above-described three-dimensional laser measuring instrument. And the height of the bed 90 is adjusted so that this axial center line may extend in a horizontal plane.

Step S5: When the bed 90 is leveled in step S3 or step S4, the surface state of the rail 91 is subsequently measured using the above three-dimensional laser measuring instrument. From this measured value, the state (the degree of wear, etc.) of the rail 91 before processing is determined. The measurement information obtained here is held in the scraping apparatus 100 by being input to the scraping apparatus 100 by an operator, for example.
If it is determined in step S2 that the reference plane is sufficiently horizontal (for example, if the deviation between the reference plane and the horizontal plane is within an allowable range), step S3 to step S4 are skipped, and step S5 is performed. Processing can be performed.

  Step S6: Subsequently, the position adjustment of the side rails 1a and 1b temporarily placed in Step S1 is performed. Specifically, using the above-described three-dimensional laser measuring instrument, the installation level of the rail portion 11 is measured, and based on the measurement result, the operator can make the rail portion 11 extend in the horizontal plane. Each height adjusting member 14 is adjusted (leveling of the rail portion 11). Further, the straightness of each rail portion 11 and the distance between the pair of rail portions 11 using the above-described three-dimensional laser measuring instrument and jigs (jigs for bringing parallelism) provided on the side rails 1a and 1b. Measure the parallelism, the parallelism between each rail portion 11 and the rail 91 of the lathe 9, etc., and based on the measurement results, each rail portion 11 and the rail 91 extend straight in parallel with each other, An operator adjusts the connecting members and the like of the frame pieces 15 (parallelism of the rail portion 11). When the position adjustment of the side rails 1a and 1b is completed, the side rails 1a and 1b are fixed (main fixing).

Step S7: Subsequently, the carriage 2 is installed on the pair of side rails 1a and 1b so as to be movable along the pair of side rails 1a and 1b so as to straddle the bed 90 of the lathe 9.
Thus, the installation of the scraping apparatus 100 is completed.

<3. Operation of Kisage Processing Device 100>
Next, the operation of the scraping apparatus 100 will be described with reference to FIG. 5 in addition to FIGS. FIG. 5 is a diagram showing a flow of operation of the scraping apparatus 100. A series of processing described below is performed under the control of the control unit 6.

  Step S <b> 11: The control unit 6 accepts an operator's input, thereby setting various processing parameters (such as the size and depth of the recesses to be formed, the interval between formations of the recesses, the pushing amount of the blade 40, and the like) related to scraping. decide. In determining the processing parameters, it is also preferable to consider the measurement information on the surface state of the rail 91 before processing, which is obtained in step S5. Specifically, for example, the amount of wear of the rail 91, the presence or absence of a flaw, and the position and depth of a flaw if there is a flaw are specified from the measurement information, and the parameters related to scuffing are adjusted based on this May be.

  Step S12: Subsequently, the control unit 6 adjusts the position of the scraping processing unit 4 with respect to the rail 91. Specifically, the control unit 6 controls the R drive mechanism to adjust the posture of the support body 41, whereby the tip of the blade 40 is determined at a predetermined angle with the surface of the rail 91 (for example, in step S11). In such a manner that the angle is an angle defined by the processed parameters). Then, the control unit 6 controls the Y drive mechanism 53 to adjust the Y position of the first base plate 52, thereby matching the Y position of the blade 40 with the Y position of the rail 91. Then, the control unit 6 controls the Z drive mechanism 56 to adjust the height of the second base plate 55, thereby arranging the blade 40 at a height such that the tip of the blade 40 comes into contact with the surface of the rail 91. . In step S12, the control unit 6 uses the above-described three-dimensional laser measuring device to measure the positional relationship between the blade 40 and the rail 91 (an angle formed by the blade 40 and the rail 91, a separation distance, etc.). Based on the measurement result, it is preferable to adjust the position of the scraping portion 4 so that the angle and the separation distance are within a predetermined allowable range.

Step S13, Step S14: When the input of the machining start instruction from the operator is received, the control unit 6 controls the carriage drive mechanism 3 to start the movement of the carriage 2 (movement along the side rails 1a and 1b). At the same time, the scraping processing unit 4 starts scraping processing (specifically, the driving unit 46 and the moving body 47 are controlled to start the cutting operation of the blade 40). That is, the scraping portion 4 is scraped on the surface of the rail 91 while moving the carriage 2 along the pair of side rails 1a and 1b.
As described above, the positions of the rail portions 11 of the side rails 1a and 1b are strictly adjusted so as to extend horizontally and straight. Therefore, the surface of the rail 91 is scraped with the scraping portion 4 mounted on the carriage 2 that is guided while being guided by the rail portion 11, so that the surface of the rail 91 is accurately scraped. Can do.

  When the carriage 2 moves along the side rails 1a and 1b and reaches from one end of the rail 91 to the other end, scoring is performed on a belt-like region extending along the X direction on the surface of the rail 91. Ends. Thereafter, if necessary, the scraping portion 4 is moved by a minute distance in the Y direction (specifically, the distance corresponding to the width of the belt-like region of the first base plate 52 along the Y guide rail 51). The carriage 2 moves along the side rails 1a and 1b in the direction opposite to the previous movement direction after the height position and angle of the scraping portion 4 with respect to the rail 91 are readjusted. Is done. As a result, scoring is performed on the band-shaped region adjacent to the band-shaped region that has been scuffed first. In this way, the surface on which the scraping process is to be performed on the surface of the rail 91 by the carriage 2 being reciprocated along the side rails 1a and 1b while sandwiching the slight movement of the scraping processing part 4 in the Y direction. The entire region can be scraped.

  Step S15, Step S16: The control unit 6 stops the carriage 2 at a predetermined position when the entire scoring process of the surface area to be scored on the surface of the rail 91 is completed (YES in Step S15) (Step S15). Step S16).

<5. Effect>
According to the above-described embodiment, the control unit 6 moves the carriage 2 along the pair of side rails 1a and 1b, while the rail 91 as a target surface is applied to the scraping processing section 4 mounted on the carriage 2. The surface is scraped. Here, the pair of side rails 1a and 1b is not laid on the installation machine (the lathe 9 in the above example), but is laid on the floor 101 on which the installation machine is arranged. The carriage 2 on which the part 4 is mounted can travel straight regardless of the state of the upper surface of the installation machine. Therefore, the scraping portion 4 can accurately form the concave portions at the predetermined positions and at the predetermined intervals. Further, since the carriage 2 is secured so that it can move smoothly, the speed of the carriage 2 can be set to a relatively high speed, and the time required for scraping can be shortened. As described above, according to the above-described embodiment, it is possible to scrape the target surface (the lathe rail 91 in the above example) in the installation machine with sufficient accuracy and speed.

  In addition, according to the above embodiment, since the pair of side rails 1a and 1b are laid on the floor 101, position adjustment of the side rails 1a and 1b (for example, leveling and paralleling of the side rails 1a and 1b) Regardless of the state of the installation machine, it can be performed with high accuracy. By scoring the target surface of the installation machine with the scoring processing unit 4 mounted on the carriage 2 that moves along the side rails 1a and 1b adjusted with high precision, the target surface can be scored with particularly high accuracy. Can be processed.

  Moreover, according to said embodiment, since the scraping process part 4 mounted in the trolley | bogie 2 can be made into arbitrary positional relations with respect to an installation machine with the position change mechanism 5, it is on various surfaces of an installation machine. On the other hand, it is possible to perform free scoring. For example, it is possible to perform scoring of a surface whose normal direction is vertically upward, or scoring of a surface whose normal direction is horizontal.

  Further, according to the above embodiment, a wide range of processing can be performed by the scraping processing unit 4. In other words, a large installation machine can be scraped. That is, the processing range in the X direction by the scraping portion 4 is defined by the lengths of the side rails 1a and 1b. In the above embodiment, the side rails 1a and 1b having an arbitrary length can be laid. That is, the processing range in the X direction by the scraping processing unit 4 can be set to an arbitrary length. Further, the machining range in the Y direction by the scraping portion 4 is defined by the interval between the pair of side rails 1a and 1b. In the above embodiment, the pair of side rails 1a and 1b can be laid at an arbitrary interval. . That is, the processing range in the Y direction by the scraping processing unit 4 can be set to an arbitrary length. Further, the machining range in the Z direction by the scraping portion 4 is defined by the length of the Z guide rail 54. In the above embodiment, the Z guide rail 54 is placed on the pair of side rails 1a and 1b. Since it is laid indirectly on the carriage 2, even if the Z guide rail 54 becomes heavy, no load is applied to the installation machine. Therefore, the length of the Z guide rail 54 can be set arbitrarily. That is, the machining range in the Z direction by the scraping processing unit 4 can be set to an arbitrary length.

  Further, according to the above-described embodiment, the side rails 1a and 1b are formed by connecting a plurality of frame pieces 15, 15,. Therefore, the length of the side rails 1a and 1b (length along the extending direction) can be easily changed in accordance with the size of the installation machine, and it can easily cope with a large installation machine. Moreover, since the side rails 1a and 1b can be disassembled and transferred into a plurality of frame pieces 15, 15,..., The side rails 1a and 1b can be easily transferred.

  Moreover, according to said embodiment, the some height adjustment member 14 is arranged at intervals along the extension direction of the side rails 1a and 1b. Therefore, for example, the side rails 1a and 1b can be leveled with high accuracy by adjusting the height of each part of the side rails 1a and 1b.

  Further, according to the above-described embodiment, the tip of the regulating member 13 extending from the side surfaces of the side rails 1a and 1b abuts the side surface of the installation machine, so that the side rails 1a and 1b generated due to vibration during processing or the like. Side shake can be suppressed.

<6. Modification>
In the above-described embodiment, the case where the scraping device 100 performs scraping of the rail 91 of the lathe 9 has been illustrated. However, the scraping device 100 may be a variety of devices and equipment other than the lathe 9 (for example, various types of machine tools). Scraping of machines (roll lathes, roll grinders, planars), press bolster surfaces of forging machines, rolling mill stands of iron making facilities, etc. can be performed.

  In the above embodiment, each side rail 1a, 1b is configured to be disassembled into a plurality of frame pieces 15, 15,..., But each side rail 1a, 1b is not necessarily a plurality of frame pieces 15. .., 15,... Are not required to be disassembled, and may be formed as a single piece.

  In the above embodiment, scoring is performed in the vicinity of the scoring unit 4 (specifically, for example, on both sides of the scoring unit 4 along the X direction and / or the Y direction). A sensor (for example, a laser sensor) for observing the state of the power surface may be mounted, and various parameters related to the scraping process may be adjusted based on detection information of the sensor.

  In the above embodiment, the scraping portion 4 is scraped on the surface of the rail 91 while moving the carriage 2 along the pair of side rails 1a and 1b. The scraping portion 4 may be scraped on the surface of the rail 91 while moving the base plate 2 along the carriage 2 (that is, while moving the first base plate 52 along the Y guide rail 51). . Further, the surface of the rail 91 is scraped on the scraping portion 4 while the carriage 2 is moved along the pair of side rails 1 a and 1 b and the scraping portion 4 is moved along the carriage 2. It may be done.
