The position adjustment device of ccd used to detect the shape of the external wall of the tubular body

Abstract

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 guaranteeing that a detected outer wall is always located within the effective focal length of the CCD lens, and guaranteeing that the tubular body is located at the center of an image captured by the CCD.

Description

technical field [0001] The invention relates to the technical field of CCD position adjustment, in particular to a CCD position adjustment device for detecting the shape of the outer wall of a tubular body. Background technique [0002] In the production workshop, there will be a shape of the outer wall of the tubular body that needs to be inspected, such as the external thread at the joint of the oil pipeline, or the outer diameter and surface quality of the steel pipe. The traditional inspection method is that the worker holds the inspection tool to measure, which has low efficiency and poor accuracy. . With the development of CCD technology, optical detection gradually replaces manual detection and becomes an important support for production automation. However, due to the large mass of this type of tubular body, it is difficult to ensure the relative position of the object to be detected and the CCD camera by moving the tubular body, so a device for automatically adjust...

Problems solved by technology

However, due to the large mass of this type of tubular body, it is difficult to ensure the relative position of the object to be detected and the CCD camera by moving the tubular body, so a device for automatically adjusting the position of the CCD is needed to adapt to the offset of the position of the tubular body
