For example, the clamp position adjusting plate 14 can secure a cutting amount necessary for processing the slit 11c.

  The clamp position adjusting plate 14 is formed in a substantially U shape as a whole, and has a pair of upper and lower arm plates 14a and 14b. Further, as shown in FIG. 11, the clamp position adjusting plate 14 is fixed to the apparatus main body 12 by bolts 14 c.

Next, the usage method of the processing apparatus 10 is demonstrated with reference to FIGS. 1-3.
As a processing tool such as a horusaw 27 to be mounted on the processing apparatus 10, an appropriate specification is selected and mounted according to the specification of the boiler furnace wall panel 11 to be processed. That is, a machining tool having an appropriate specification is selected according to the dimensions of the heat transfer tubes 11a and the fins 11b.

  At that time, the drill 23 is fixedly mounted on the rotating body 21 via the drill fixing seat 24, and the horusoe 27 is fixedly mounted on the rotating body 21 via the horuseau fixing seat 28, and the cutting blade provided with the cutting blade 30.

The drill fixing seat 24, the hole saw fixing seat 28 and the cutting blade fixing seat 31 can be easily fixed to the rotating body 21 by the bolt 22, and can be easily removed by loosening the bolt 22.

  In addition, the arrangement positions of the clamp saddles 15 and 19 are set in accordance with the feed amount of the processing tool such as the hole saw 27. That is, when it is necessary to adjust the relative position of the clamp saddles 15 and 19 with respect to the apparatus main body 12, the clamp saddles 15 and 19 are disposed on the clamp position adjusting plate 14 that has been prepared in advance according to the processing specifications. Then, the clamp position adjusting plate 14 is fixed to the apparatus main body 12.

  The processing apparatus 10 is fixed to the heat transfer tube 11a to be processed by the clamp saddles 15 and 19. At this time, the heat transfer tube 11a is clamped from above and below by the engagement groove portion 15c of the clamp saddle 15 and the engagement groove portion 19a of the clamp saddle 19, so that there is no misalignment during processing.

  Next, the switch 12b of the apparatus main body 12 is turned on, the feed knob 13 is turned by a predetermined amount, and the above-described processing tool such as the horusaw 27 is fed forward, and the boiler furnace wall panel 11 is subjected to predetermined processing. The rotational speed of the processing tool is adjusted by turning the pneumatic control valve 12c.

  Specifically, as shown in FIG. 1, the rotating drill 23 is inserted into the opening of the heat transfer tube 11a, and the inner diameter in the vicinity of the opening is enlarged, so that the protrusion of the inner peripheral surface of the heat transfer tube 11a is increased. A strip (not shown) can be easily and quickly cut off. That is, if the apparatus main body 12 is clamped at a predetermined position of the boiler furnace wall panel 11, it is only necessary to insert the drill 23 into the opening of the heat transfer tube 11 a, so that a highly skilled technique is unnecessary.

  Further, as shown in FIG. 2, by sending the rotating forcible 27 toward the fins 11b and 11b (see FIGS. 15 and 16) located on both sides of the heat transfer tube 11a, both sides of the heat transfer tube 11a are sent. The predetermined slits 11c and 11c (see FIGS. 15 and 16) can be formed simultaneously.

  Therefore, if the apparatus main body 12 is clamped at a predetermined position of the boiler furnace wall panel 11, it is only necessary to send the hole saw 27 toward the fins 11b and 11b. The slits 11c and 11c can be provided in the fins 11b and 11b.

  Moreover, as shown in FIG. 3, the outer peripheral edge part of the opening part of the heat-transfer tube 11a can be grooved by sending the rotating cutting blade 30 toward the heat-transfer tube 11a. At this time, the shaft portion 31b is inserted into the opening of the heat transfer tube 11a and is regulated so as not to be misaligned during processing. In this way, if the apparatus main body 12 is clamped at a predetermined position of the boiler furnace wall panel 11, it is possible to perform groove processing only by sending the cutting blade 30 toward the heat transfer tube 11 a, so that a highly skilled technique is unnecessary. is there.

  That is, since three types of machining operations can be performed by one machining apparatus 10, an increase in the number of road tools can be suppressed, and a great deal of time and labor is spent on preparation and transportation of the road tools. Therefore, the work cost can be reduced and the construction period can be shortened. Further, unlike the prior art, since it is not necessary to use a plurality of processing machines, it is not necessary to get used to the handling of individual processing machines, and a high degree of skill is not required, so that it is easy to secure work personnel.

  In particular, in slit processing, the slits 11c and 11c can be simultaneously formed on both sides of the heat transfer tube 11a in one processing operation. For this reason, compared with the conventional manual processing using a disc grinder or the like, advanced skill is not required, the working speed can be significantly increased, and processing can be performed with high accuracy. .

  Moreover, since the processing apparatus 10 includes the clamp position adjusting plate 14 that adjusts the relative positions of the clamp saddles 15 and 19 with respect to the apparatus main body 12, the processing amount of the processing tool can be adjusted. That is, by providing the processing apparatus 10 with the clamp position adjusting plate 14, for example, it is possible to ensure a cutting amount necessary for processing the slit 11c.

Further, the guide support members 35 and 36 have locking portions 35 a and 36 a that can come into contact with one side surface of the apparatus main body 12. The locking portions 35 a and 36 a are fixed to one side surface of the apparatus main body 12 by a bolt 38.

  As described above, according to the processing apparatus 10 according to the second embodiment, the apparatus main body 12 is engaged so as to be sandwiched from above and below by the guide support members 35 and 36 of the clamp position adjusting plate 14. For this reason, when the clamp position adjusting plate 14 is fixed to the apparatus main body 12 by the bolt 38, the operator does not need to position the clamp position adjusting plate 14 while lifting it, and the clamp position adjusting plate engaged with the apparatus main body 12 is used. Positioning can be easily performed by sliding 14 forward and backward.

  In each of the above embodiments, the drilling process on the heat transfer tube 11a, the slit process on the fins 11b and 11b, and the groove process on the heat transfer tube 11a have been described as examples.
