Regulation and detection tracing instrument for double-layered copper brazed steel tube production machine

The utility model relates to a shunting inspection tracker used for double-layer copper soldering steel pipe maker, belonging to the detection device field for the angle deviation of rolling pipe of the double-layer pipe maker. The utility model consists of a bearing external sleeve, a bearing, a bearing internal sleeve, a core rod connecting plate, a calibration plate and a pointer. The bearing is arranged between the bearing internal sleeve and the bearing external sleeve; the external side of the bearing internal sleeve is provided with a core rod connecting plate. The bearing external sleeve is provided with the calibration plate. During running, the pointer of the bearing internal sleeve does not produce the rotation displacement relevant to the calibration plate, which means the shunting is qualified and the production can be normally carried out, otherwise the shunting is unqualified. The utility model can be directly utilized to check and track the shunting of the pipe maker to see whether the shunting is in place and whether the production is normal. By the display of the pointer, non-visible, non-touchable, no-detection and experience which is adopted for trying to adjust in the past are changed into macro controllable and correction in time, thus the quality of double-layer pipe is fully improved and the utility model is suitable for the shunting of the double-layer pipe maker with all specifications.
