Position adjustment device for CCD for detecting shape of outer wall of tubular body

The invention provides a position adjustment device for a CCD for detecting the shape of the outer wall of a tubular body, and the device comprises a support assembly (100), a CCD camera assembly (200), and an extending arm assembly (16). The support assembly (100) comprises a Y-direction guide rail (19) and a Z-direction guide rail (26), wherein the Y-direction guide rail (19) and the Z-directionguide rail (26) are slidingly connected through a Z-direction sliding block (27). The CCD camera assembly (200) and the extending arm assembly (16) are slidingly connected to the Y-direction guide rail (19) through a CCD sliding block (20) and an extending arm sliding block (28). The CCD sliding block (20) is connected with the extending arm sliding block (28) through a fixed connection plate (21), or the CCD sliding block (20) is separated from the extending arm sliding block (28). The device can achieve a purpose that a CCD automatically moves with the deviation of the position of the tubular body, thereby guarante
