Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to an angle measuring tool for shipbuilding. Background Art

[0002] During the shipbuilding process, it is necessary to weld the ship's welded components, and during welding, there are requirements for the angle between the component body and the welded part. Therefore, it is necessary to use an angle measuring device to measure the angle of the ship component. The angle measuring device is generally composed of a semicircular ruler plate and an indicator plate. The semicircular ruler plate contacts the upper end surface of the ship component, and the indicator plate coincides with the angle surface on the ship component. The indicator plate points out the corresponding scale on the semicircular ruler plate. However, the light at the location where some ship components are placed is dim. After the indicator plate points out the corresponding scale on the semicircular ruler plate, the scale value cannot be seen clearly. Therefore, the semicircular ruler plate needs to be moved to a bright place. When moving the semicircular ruler plate, the indicator plate is easy to rotate relative to the semicircular ruler plate, thereby changing the scale indicated on the semicircular ruler plate, resulting in errors in the read scale and reducing the measurement accuracy. Utility Model Content

[0003] The utility model aims to solve the problem in the prior art that when the semicircular ruler plate is moved, the indicating plate is prone to relative rotation with the semicircular ruler plate, thereby changing the scale indicated on the semicircular ruler plate, resulting in errors in the read scale and reducing the measurement accuracy, and proposes an angle measuring tool for shipbuilding.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An angle measuring tool for ship construction is designed, including a semicircular ruler plate, a scale is opened on the semicircular ruler plate along the arc direction, a connecting shaft is rotatably connected to the semicircular ruler plate, an indicator plate is fixedly connected to the connecting shaft, the indicator plate is in contact with the semicircular ruler plate, one end of the connecting shaft is fixedly connected to a mounting plate, and an anti-slip mechanism for fixing the indicator plate is connected to the mounting plate.

[0006] Preferably, an arc-shaped hole is provided on the semicircular ruler plate.

[0007] Preferably, the semicircular ruler plate is provided with an anti-skid rubber layer, and the anti-skid rubber layer is in contact with the indicator plate.

[0008] Preferably, the anti-slip mechanism comprises a threaded rod, a threaded hole is formed on the mounting plate, the threaded rod cooperates with the threaded hole, one end of the threaded rod is rotatably connected to a pressure block, and the pressure block can contact the indicator plate.

[0009] Preferably, the other end of the threaded rod is fixedly connected to a rotating block.

[0010] Preferably, the rotating block is connected with anti-slip grooves.

[0011] Preferably, both sides of the indicator plate are connected to a limiting mechanism, and the limiting mechanism includes a guide column, the guide column is fixedly connected to the indicator plate, a limiting plate is slidably inserted on the guide column, the limiting plate passes through the side of the indicator plate, a spring is fixedly connected to the indicator plate, and one end of the spring is fixedly connected to the limiting plate.

[0012] The utility model provides an angle measuring tool for shipbuilding, which has the following beneficial effects:

[0013] The threaded rod is driven to rotate by the rotating block, and the threaded rod drives the pressing block to move toward the indicating plate after the rotation. After the pressing block moves a certain distance, it contacts the indicating plate and squeezes and fixes it. The anti-skid rubber layer increases the friction between the indicating plates. When the pressing block squeezes and fixes the indicating plate, the indicating plate will not slide.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The anti-skid mechanism 8 includes a threaded rod 81, a threaded hole is opened on the mounting plate 7, the threaded rod 81 cooperates with the threaded hole, one end of the threaded rod 81 is rotatably connected to a pressure block 82, the pressure block 82 can contact the indicator plate 5, and the other end of the threaded rod 81 is fixedly connected to a rotating block 83, and the rotating block 83 is connected with anti-skid patterns.

[0023] Working process:

[0024] When measuring the angle of a ship component, the bottom end of the semicircular ruler 1 contacts the end face of the ship component, and the indicating plate 5 is rotated so that the indicating plate 5 coincides with the angle surface on the ship component. The indicating plate 5 indicates the corresponding scale on the semicircular ruler 1, and then the rotating block 83 is rotated. The rotating block 83 drives the threaded rod 81 to rotate, and the threaded rod 81 drives the pressing block 82 to move toward the indicating plate 5 after rotating. After the pressing block 82 moves a certain distance, it contacts the indicating plate 5 and squeezes and fixes it. One side of the indicating plate 5 contacts the anti-slip rubber layer 6, and the anti-slip rubber layer 6 increases the friction between the indicating plates 5 and the indicating plates 5. When the pressing block 82 squeezes and fixes the indicating plate 5, the indicating plate 5 will not slide. When the semicircular ruler 1 is moved, the indicating plate 5 will not slide on the semicircular ruler 1, thereby not changing the scale value indicated by the indicating plate 5, thereby improving the accuracy of the angle measurement.

[0025] Example 2: In Example 1, when measuring the angle, it is necessary to move the indicator plate 5 to coincide with the angle surface on the ship component. Due to the dim light, it is impossible to determine whether the indicator plate 5 coincides with the angle surface on the ship component. Figure 5As another preferred embodiment of the present invention, the difference from embodiment 1 is that both sides of the indicator plate 5 are connected to a limiting mechanism 9, the limiting mechanism 9 includes a guide column 91, the guide column 91 is fixedly connected to the indicator plate 5, a limiting plate 92 is slidably inserted on the guide column 91, the limiting plate 92 passes through the side of the indicator plate 5, a spring 93 is fixedly connected to the indicator plate 5, one end of the spring 93 is fixedly connected to the limiting plate 92, when the indicator plate 5 is rotated, the limiting plate 92 is pressed downward, and the limiting plate 92 moves smoothly under the guidance of the guide column 91, the limiting plate 92 extends from the side of the indicator plate 5, and the limiting plate 92 squeezes the spring 93 after moving downward, and the spring 93 generates elastic force after being compressed. During the rotation of the indicator plate 5, after the limiting plate 92 contacts the angle surface on the ship component, it is ensured that the indicating plate 5 coincides with the angle surface on the ship component, which is convenient for determining that the indicating plate 5 coincides with the angle surface on the ship component, and after the pressure is removed, the limiting plate 92 is driven to move and reset under the elastic force of the spring 93.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
