Description

Length detection tool for thin tube hole or thin shaft hole

Technical Field

The invention relates to the field of ship construction or design, in particular to a detection tool for electronically detecting the length of a ship stern shaft section or other steel straight pipes, which is used for accurately detecting the distance between two parallel end surfaces of a pipeline or a shaft hole under the condition that a length pull rule of a stern shaft section stern shaft hole is inconvenient to detect or the distance pull rule of other axial pipelines (round pipes or square pipes) is inconvenient to detect (the pipe diameter is too thin).

Background

After the stern shaft section of the ship body is manufactured completely, the length of a stern shaft hole is required to be detected (as shown in figure 6), because the section outer plate is a hyperbolic plate type, the distance between the end faces of head and tail castings can be detected only by a measuring tape detection mode through the stern shaft hole when the castings are detected, the detection data is used as section completion data, shafting installation can be carried out only when the data reaches a tolerance, and the shafting installation precision is determined by the detection precision of the length of the stern shaft tube; the traditional measurement mode is that 2-3 individuals come the joint measurement and just can accomplish, it is alone on the tail casting terminal surface to detect, confirm zero point, and fix the chi strip, the chi strip passes through the stern shaft hole, the first foundry goods is detected by one individual slide bar down, and with the help of straight plate chi extension first foundry goods terminal surface, the length of stern shaft pipe is regarded as with the crossing point reading of chi strip, the slide bar in-process, certain deviation can appear when the slide bar elasticity and measurement person see the chi reading, cause the length measurement value of stern shaft pipe to have the deviation, influence shafting installation accuracy, so the shafting need take more accurate measurement mode to detect, the shafting installation accuracy standard is very high, only take accurate measurement mode can guarantee the axle installation accuracy.

Above-mentioned tubule hole or thin axle hole length detection frock, further, range finding bottom plate lower surface center department is provided with first strengthening purlin, first strengthening purlin center is fixed with horizontal bubble. And judging whether the distance measuring device is flatly placed when placed on the bow casting through the horizontal bubbles.

Above-mentioned tubule hole or thin axle hole length detection frock, further, reflection bottom plate lower surface center department is provided with the second and strengthens the purlin, second is strengthened purlin center department and is fixed with horizontal bubble. And judging whether the reflecting device is placed on the stern casting or not through the horizontal bubbles.

According to the length detection tool for the thin tube hole or the thin shaft hole, furthermore, the distance measuring device is fixed on a bow casting, and the reflecting device is fixed on a stern casting.

In the tool for detecting the length of the thin tube hole or the thin shaft hole, further, the first magnet is perpendicular to the first vertical plate, and the second magnet is perpendicular to the second vertical plate.

Above-mentioned tubule hole or thin axle hole length detection frock, further, the number of first button magnet with second button magnet is two or more.

The invention has simple structure, and can quickly and accurately measure the distance of a thinner shaft hole or hole by matching the distance measuring device with the reflecting device.
