It is in contact with both ends in the hand direction. The stopper S may be slidable along the short direction of the outer plate 2 on the connecting portion 22b or the connecting portion 24b, for example. In this case, the position of the stopper S can be adjusted according to the dimension of the outer plate 2. A plurality of pairs of stoppers S may be provided along the longitudinal direction of the outer plate 2.

  As shown in FIG. 1, the rotation mechanism 30 has a pair of support portions 31 and 31 that rotatably support the frame body 10 around a horizontal rotation axis X, and the frame body is driven by a driving force of a motor (not shown). 10 is rotated around the rotation axis X. For example, the rotation axis X coincides with the center line of the frame 10 when viewed from the longitudinal direction of the frame 10. The support portions 31 are arranged on one side and the other side in the longitudinal direction of the frame body 10 so as to face each other across the rotation axis X.

Each elevating part 41 includes a fixed part 42 fixed to the support part 31 of the rotation mechanism 30, and a pair of movable parts 43 and 43 that move the fixed part 42 in the vertical direction with respect to the installation surface of the outer plate holding device 1. And a pair of guide portions 44 and 44 for guiding the movement of the fixed portion 42 by the movable portion 43.

  For example, the fixing portion 42 has a bar shape and extends in the horizontal direction, and is fixed to the support portion 31 of the rotation mechanism 30 at an intermediate portion. The movable portion 43 has, for example, a rod shape and extends in the vertical direction, and supports the fixed portion 42 with respect to the pedestal portion 45. The movable portion 43 is, for example, a pneumatic telescopic pole that expands and contracts by air from a tank (not shown). Operation | movement of the movable part 43 is controlled by the control apparatus mentioned above. The guide portion 44 has, for example, a rod shape, extends in the vertical direction from the pedestal portion 45, and is inserted through the fixed portion 42.

  The elevating mechanism 40 elevates and lowers the frame body 10 between, for example, a lower position (FIG. 1) where the welding operation of the welded portion W is performed and an upper position (FIG. 4) above the lower position. The lower position is set to a position where the frame body 10 is not in contact with the installation surface. The upper position is set to a position where the frame 10 is not in contact with the installation surface even if the frame 10 is rotated by the rotation mechanism 30.

  In addition, the outer plate holding device 1 includes a plurality of (four in this example) stoppers 5 that come into contact with the lower surface of the frame body 10 when the outer plate 2 is horizontal and the frame body 10 is positioned at the lower position. Is provided. Each stopper 5 is erected on the installation surface. The outer plate holding device 1 has a backing device (not shown) that supports the lower surface of the welded portion W of the outer plate 2 when the outer plate 2 is horizontal and the frame body 10 is positioned at the lower position. Is provided. For example, the backing device is installed on a rail (not shown) so that the position relative to the welded portion W can be adjusted, and is movable in the horizontal direction.

  Then, the processing method of the outer plate | board 2 using the outer plate holding | maintenance apparatus 1 is demonstrated, referring FIGS. 3-8. First, as shown in FIG. 4, both the first clamping members 21 and 22 and the second clamping members 23 and 24 are opened, the one surface 2a of the outer plate 2 faces upward, and the other surface 2b is downward. The outer plate 2 is arranged in the frame of the frame body 10 so as to face. At this time, the frame body 10 is positioned at the lower position by the elevating mechanism 40. Further, at this time, the outer plate 2 is positioned with respect to the frame body 10 by arranging the outer plate 2 between the stoppers S. The arrangement of the outer plate 2 in the frame of the frame body 10 may be performed by, for example, human power or using an apparatus.

  Subsequently, as shown in FIG. 1, both the first clamping members 21 and 22 and the second clamping members 23 and 24 are closed, and the outer plate 2 is held in the frame of the frame body 10 by the holding mechanism 20. (Step S1, holding step). Subsequently, as shown in FIG. 5, the frame body 10 is raised from the lower position to the upper position by the elevating mechanism 40 (step S2). Subsequently, as shown in FIGS. 5 and 6, the frame 10 is rotated around the rotation axis X by the rotation mechanism 30 so that the one surface 2 a of the outer plate 2 faces downward and the other surface 2 b faces upward. (Step S3, rotation step). In FIG. 5, the rotating frame body 10 is indicated by a two-dot chain line. Subsequently, as shown in FIG. 7, the frame body 10 is lowered from the upper position to the lower position by the elevating mechanism 40 (step S4).

  Subsequently, as shown in FIG. 8, the other surface 2b of the outer plate 2 is processed (step S5, processing step). For example, a polishing operation is performed on the welded portion W on the other surface 2 b of the outer plate 2. This polishing operation is performed by an operator using a polishing machine, for example. The other surface 2b of the outer plate 2 is, for example, a surface constituting the outer surface of the vehicle body, and a polishing operation for the welded portion W is performed to improve the appearance. FIG. 8 shows the weld W after the polishing operation is completed.

  After the polishing operation is completed, the frame body 10 is raised from the lower position to the upper position by the lifting mechanism 40 (step S6). Subsequently, the frame body 10 is rotated around the rotation axis X by the rotation mechanism 30 so that the one surface 2a of the outer plate 2 faces upward and the other surface 2b faces downward (step S7). Subsequently, the frame body 10 is lowered from the upper position to the lower position by the elevating mechanism 40 (step S8). Subsequently, both the first clamping members 21 and 22 and the second clamping members 23 and 24 are opened, and the outer plate 2 is taken out from the frame body 10. The extraction of the outer plate 2 from the frame body 10 may be performed by, for example, human power or using an apparatus.

  Subsequently, the one surface 2a of the outer plate 2 is processed. For example, a bone member for improving the strength is attached to the one surface 2 a of the outer plate 2. More specifically, for example, the outer plate 2 taken out from the frame body 10 is moved to the place where the bone member is attached while the one surface 2a faces upward and the other surface 2b faces downward. It conveys and attaches a bone member to the one surface 2a of the outer plate 2 by welding.

  In the outer plate holding device 1 described above, by rotating the frame body 10 around the horizontal rotation axis X by the rotation mechanism 30 in a state where the outer plate 2 is held in the frame of the frame body 10 by the holding mechanism 20, The direction of the outer plate 2 can be reversed up and down. Thereby, since the direction of the outer plate 2 can be reversed while the outer plate 2 is stably held, the reversing operation can be facilitated, and the workability of processing on the outer plate 2 for a railway vehicle can be improved.

  The outer plate holding device 1 further includes an elevating mechanism 40 that elevates and lowers the frame body 10 in the vertical direction. Accordingly, the frame body 10 can be disposed at the upper position so that the frame body 10 is not in contact with the installation surface of the outer plate holding device 1 during rotation by the rotation mechanism 30, and the work is performed at the time of working on the outer plate 2. The frame body 10 can be arranged at a lower position below the upper position so as to facilitate.

  The holding mechanism 20 includes a pair of first clamping members 21 and 22 that support one side of the outer plate 2 and a pair of second clamping members 23 and 24 that support the other side of the outer plate 2. ing. Thereby, the outer plate | board 2 can be hold | maintained more stably.

  The first clamping members 21 and 22 include rod-shaped clamping parts 21 a and 22 a extending along the longitudinal direction of the outer plate 2, and a plurality of connection parts 21 b and 22 b that connect the clamping parts 21 a and 22 a to the frame body 10. The second holding members 23 and 24 have rod-like holding portions 23a and 24a extending along the longitudinal direction of the outer plate 2, and a plurality of connecting portions 23b for connecting the holding portions 23a and 24a to the frame body 10. , 24b. Thereby, the 1st clamping members 21 and 22 and the 2nd clamping members 23 and 24 can be simplified and reduced in weight. In addition, the work surface of the outer plate 2 can be widely exposed in a state of being sandwiched between the first sandwiching members 21 and 22 and the second sandwiching members 23 and 24.

  In addition, a buffer material 29 is provided at a portion of the first clamping members 21 and 22 and the second clamping members 23 and 24 that are in contact with the outer plate 2. Thereby, abrasion, damage, and the like of the outer plate 2 due to contact with the first clamping members 21 and 22 and the second clamping members 23 and 24 can be suppressed.

  Further, the second holding member 23 has a holding position of the outer plate 2 by the second holding members 23 and 24 in a thickness direction of the frame body 10 with respect to a holding position of the outer plate 2 by the first holding members 21 and 22. An offset member 28 to be offset is detachable. Thus, by changing the shape of the offset member 28, the outer plate 2 having a partially curved shape can be handled by the outer plate holding device 1.

  For example, an offset member 28A as shown in FIG. 9 may be used. In this modification, the other end side in the short direction of the outer plate 2 is curved toward the second clamping member 23 side. The offset member 28A is detachably attached to each of the second holding members 23 and 24, and holds the other end side of the outer plate 2 in the short direction. Each of the pair of offset members 28 </ b> A has a shape corresponding to the curved shape on the other end side in the short direction of the outer plate 2. A stopper S is provided on the offset member 28A on the second clamping member 24 side. In this modification, the outer plate 2 formed by the first holding members 21 and 22 is positioned at the position where the outer plate 2 is held by the second holding members 23 and 24 so as to correspond to the curved shape on the other side in the short direction of the outer plate 2. Can be offset in the thickness direction of the frame 10 with respect to the sandwiching position.

  In addition, a pair of stoppers S that come into contact with both ends of the outer plate 2 in the direction orthogonal to the rotation axis X are provided on the connecting portion 22b of the first holding member 22 and the connecting portion 24b of the second holding member 24. . Thereby, when the outer plate 2 is inclined by the rotation of the frame body 10, it is possible to suppress the position of the outer plate 2 from being displaced due to gravity. Further, when the outer plate 2 is arranged in the frame of the frame body 10, the outer plate 2 can be easily positioned with respect to the frame body 10 by arranging the outer plate 2 between the stoppers S.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, in the above-described embodiment, the polishing of the welded portion W is exemplified as an example of the processing to be performed on the other surface 2b of the outer plate 2 in step S5. However, instead of or in addition to this, an electrolytic operation of spot welding marks is performed. Alternatively, other processing may be performed. Moreover, although attachment of the bone member was illustrated as an example of the process performed to the one surface 2a of the outer plate 2, other processes may be performed instead of or in addition to this. Further, only the processing of the other surface 2b may be performed without processing the one surface 2a of the outer plate 2. Further, the outer plate 2 may be constituted by a single plate member that is integrally formed in advance.

  Moreover, in the said embodiment, the 1st clamping member 22 and the 2nd clamping member 24 may turn freely similarly to the 1st clamping member 21 and the 2nd clamping member 23. FIG. For example, each connecting portion 22b of the first holding member 22 and each connecting portion 24b of the second holding member 24 are pivotally supported by the long side portion 11 of the frame 10, and the first holding member 22 and the second holding member 24 are long. It may be rotatable around an axis along the side portion 11. In this case, for example, after polishing the other surface 2b of the outer plate 2 in step S5, the first clamping member 22 and the second clamping member 24 are rotated to open the other surface 2b side of the outer plate 2. Thus, an operation of peeling off the protective film that is attached to the other surface 2b for surface protection can be performed. After the operation of peeling off the protective film is completed, the first clamping member 22 and the second clamping member 24 are rotated to close the other surface 2b side of the outer plate 2, and the lifting mechanism is the same as in the above embodiment. The frame 10 may be raised from the lower position to the upper position by 40 (step S6).

  Further, the outer plate 2 only needs to be positioned in the frame of the frame 10 when viewed from the thickness direction of the frame 10, and is not necessarily when viewed from the direction along the in-plane direction of the frame 10. It does not have to be located within the frame of the frame body 10. That is, a part of the outer plate 2 may be located outside the frame 10 when viewed from the direction along the in-plane direction of the frame 10. The first clamping member 21 and the second clamping member 23 may be rotated by driving means other than the air cylinder 25, and the rotation mechanism 30 may rotate the frame body 10 by driving means other than the motor. . Further, the movable portion 43 of the elevating mechanism 40 may move the fixed portion 42 by driving means other than the pneumatic telescopic pole.

  Moreover, the buffer material 29 should just be provided in at least one part of the contact part with the outer plate 2 in the 1st clamping members 21 and 22 and the 2nd clamping members 23 and 24, and a contact part like the said embodiment. May be provided on a part of the contact part, or may be provided over the entire contact part. Further, the offset member 28 may be detachable from the second clamping member 23 by means other than bolt fastening such as temporary fixing welding. Temporary fixing welding means temporarily fixing members by spot welding or the like so that they can be removed by applying a load of a predetermined amount or more. Further, the offset member 28 does not necessarily have to be detachable from the second holding member 23. In this case, for example, in the closed state, the second sandwiching member 23 is positioned in the same horizontal plane as the first sandwiching member 21, and the second sandwiching members 23, 24 attach the outer plate 2 in the same manner as the first sandwiching members 21, 22. Hold directly. Further, the stopper S may be provided on the connecting portion 21 b of the first holding member 21 or the connecting portion 23 b of the second holding member 23.
