Abstract
An inspection tool for inspection of a hole of a metallic lug, including, a first arm, a second arm, a third arm, and a housing element, wherein the first arm, the third arm and the housing element may vary their position independently of each other in relation to the second arm. Also, the present invention discloses an inspection device for inspection of a metallic lug that comprises an inspection tool and a probe housed in the housing element, and a method for detecting cracks around metallic lug.
Claims16
An inspection tool for inspection of a hole of a metallic lug, comprising,
- a first arm comprising:
- a first lateral part with a first lateral part end, the first lateral part end being configured to be in contact with the hole of the metallic lug,
- a central part, and
- a second lateral part with a second lateral part end, the second lateral part end being configured to be in contact with the hole of the metallic lug,
- the first lateral part and the central part forming a first angle,
- the second lateral part and the central part forming a second angle, and said central part comprising a first guiding cavity,
- a second arm comprising:
- a second guiding cavity, and
- two ends, wherein each of the two ends comprise respective first and second guiding projections,
- a third arm comprising:
- a third guiding cavity,
- a first end, and
- a second end,
- wherein the first end and the second end are configured to be in contact with the hole of the metallic lug, and
- a housing element comprising:
- a first housing part,
- a second housing part, and
- a third guiding projection,
- wherein the first arm, the third arm and the housing element vary their position independently of each other in relation to the second arm.
A method for detecting cracks at an edge of a hole in a metallic lug comprising:
- measuring the diameter of the hole of the metallic lug,
- providing an inspection device in a housing element of an inspection tool, wherein the inspection tool includes a first arm configured to contact the edge of the hole, a second arm slidably connected to the first arm and supporting the housing element, and a third arm slidably connected to the second arm and configured to contact the edge of the hole,
- positioning the inspection device on surface of the metallic lug around the hole of the metallic lug,
- sliding the inspection tool around the hole of the lug, and
- detecting cracks in the metallic lug at the edge of the hole.
An inspection tool and inspection device assembly configured for inspection of a hole of a metallic lug, the inspection tool and inspection device assembly comprising,
- a first arm including a central part having a first guiding cavity, a first lateral part extending at a first angle that is an acute angle from a first end of the central part and a second lateral part extending from and at a second angle that is an acute angle from a second end of the central part, opposite to the first end, wherein the first and second lateral parts are configured to abut the hole;
- a second arm having a first end slidably engaging the first guiding cavity of the first arm and a second end;
- a housing element slidably engaged in a second guiding cavity in the second arm, wherein the housing element includes arms each configured to grasp the inspection device;
- and
- a third arm having a third cavity configured to slidably engage the housing element, wherein the third arm has an end configured to abut the hole,
- wherein a distance between the hole and the inspection device is adjustably set based on the slidable engagement between the second arm and each of the first arm and the third arm.
