でき々いので前記不合格品の発生割合いが高い。When welding the butt joints of electric resistance welded steel pipes, weld beads that occur on the outer and inner surfaces are cut off, and then the weld beads are inspected for the presence or absence of remaining weld beads. Products with residual weld beads are considered to be rejected, and a considerable number of rejected products occur in thin tubes, and the reality is that there are no measures to prevent the occurrence of rejected products. (Cutting) This occurs due to wear and tear of the metal parts, or deviation of the metal parts during cutting, etc. In the case of the inner surface of a thin tube, it is difficult to cut while visual inspection, so the incidence of rejected products is high.

０とを設けた。As is clear from the embodiment shown in the drawings, the polishing device of the present invention has a cylindrical grindstone 1 fixed concentrically at one end, and is connected to an electric motor 80 rotating shaft 8' via a flexible shaft 4 at the other end. The grinding wheel rotating shaft 3 is rotatably supported inside one end 5' via a bearing 6, 6', and the other end 5 is a support 9 that is erected on the mount 15 of the electric motor 8. A support tube 5 is rotatably supported on the support tube 5 and has a rectangular notch 14 formed on the outer surface of one end 5' of the support tube 5, and has a rectangular notch 14 forming two parallel surfaces. 7), the legs 7' straddling the frame 7 have an arc shape with a smaller diameter than the inner diameter of the steel pipe 12 to be polished.
It is equipped with. In this embodiment, in order to rotate the support tube by a desired angle, as shown in FIG. ] #2
0 was set.
又、円筒形砥石１はナラ） ２ 、２’で挾持して回転

板上に砥石を載置する。First, as shown in FIG. 1, the support pipe 5 is placed parallel to the axis of the steel pipe 12 on the steel pipe 12, which is fixed with the remaining parts 18 and 18' of the welding bead 13 positioned directly below. A grindstone is placed on the receiving plate of the guide device 22 so that its height matches the inner surface of the steel pipe 12.
次いで、架台１５を鋼管に向ってさらに進め、砥石を鋼

部を研摩できるところまで移動できた。By swinging this reno-10, the support tube 5 repeatedly rotates from side to side, and due to this rotation, the rectangular portion 14 (Fig. 7) of the support tube 5 tilts from side to side. The contact position between the inner surface of the steel pipe 12 changes as shown in FIG. 10(A)t(B). The support tube 5' tends to run out to the left and right due to the cutting resistance caused by the rotation of the grindstone 1, but in this embodiment, the diameter of the leg of the top is 48 mm, which is two orders of magnitude smaller than the inner diameter of the steel tube. The arcuate portions of the legs contact the inner surface of the steel pipe to be polished, thereby limiting the deflection of the support tube that attempts to escape to the left and right during polishing, and the position of the grindstone can be moved to a point where the remaining portions on both sides of the weld bead can be polished. Ta.

4 and the ceiling 16' of the groove 16.
A gap C (FIGS. 3 and 5) is defined to exist, so that even if the grindstone is on the weld bead, the piece can enter and the progress of the grindstone will not be hindered.

より所望個所を研摩できる。The steel pipe to be polished may be as long as GtIL, and the support pipe is longer than the steel pipe to be polished, and therefore run-out occurs due to the cutting resistance due to the rotation of the grinding wheel. Since the rectangular notch surface formed on the 5' side of one end of the tube] 4 enters while maintaining its perpendicularity to the horizontal line, the range of deflection in the left and right direction can be limited to the difference between the outer diameter of the piece 7 and the inner diameter of the steel pipe. Bead remaining 1.8, 1
Even when polishing a case where it remains on both sides like 8',
The desired location is polished by swinging the other end 5 of the support tube with the lever 10 so that the rectangular notch surface 14 formed on the one end 5 side of the support tube is perpendicular to the respective peed remaining portions 18, 18'. can.

In the polishing device of the present invention, a rectangular notch formed near one end of a support tube has two parallel surfaces that straddle the rectangular notch portion of the support tube, and the outer surface of the leg that straddles is arc-shaped. can be,
The diameter of the circular arc is smaller than the inner diameter of the steel pipe to be polished, and the two inner surfaces of the legs of the piece receive the run-out of the support tube caused by the rotational cutting resistance of the grindstone during polishing. Since it is equipped with a piece that restricts the circular arc-shaped outer surface of the piece by receiving it on the inner surface of the steel pipe to be polished, thereby making it possible to polish a desired area, and a device that rotates the support tube, it is possible to polish the grindstone while the grindstone is being polished. It is possible to reduce the run-out of the weld bead, limit the run-out to the width of the remaining weld bead, and polish the remaining part in the shortest possible time. The grinding wheel can be positioned at the top, and the effect of grinding the remaining part of the pead accurately and quickly can be enjoyed.

果をもつ。A cylindrical grindstone is fixed concentrically at one end, and a grindstone rotating shaft is connected to the rotating shaft of an electric motor via a flexible shaft at the other end. Since it is equipped with a support tube whose end is rotatably supported on the mount side of the electric motor, the grindstone can be rotated even if the support tube is bent, and the support tube can be supported without interfering with the rotation of the grindstone. This has the effect of allowing the tube to rotate freely.
