Description

Technical Field

[0001] The present application relates to the technical field of shipbuilding, and in particular to an assembly tool and an assembly method for a tapered outer plate. Background Art

[0002] In the shipbuilding industry, a shroud is typically installed on the outer edge of the propeller at the stern of a ship to increase propeller thrust. This shroud effectively increases water velocity, thereby enhancing the propeller's propulsion efficiency, and is of great significance to the overall performance of the ship. The main outer plate of a ship's shroud adopts a conical structure. During the manufacturing process, this structure has extremely strict design requirements for precision indicators such as roundness, taper, and concentricity at both ends. Due to the large size of the outer plate of the conical shroud, it is generally assembled from multiple thick plates. Only after meeting these high-precision indicators can the subsequent welding process be carried out to ensure the final quality of the shroud.

[0003] At present, during the production stage of the fairing, the precision control tooling used by construction workers is relatively simple, mainly relying on tape measures and plumb bobs to measure and position the outer plates that make up the fairing. However, in actual operation, multiple people are required to work together to complete the measurement of the fairing outer plates, which not only increases the investment in human resources, but also easily leads to poor measurement accuracy due to coordination errors between different personnel. In addition, in the complex splicing and assembly scenarios of the fairing outer plates, it is difficult to meet the high-precision requirements, making it difficult to effectively guarantee the construction accuracy of the entire fairing production link, resulting in frequent product rework, which not only prolongs the construction period of the ship, but also increases production costs, and has a great negative impact on the progress and economic benefits of the entire ship construction project.

[0096] Example 1

[0097] This embodiment provides an assembly tool for conical outer plates, which is used to assist in the production of conical components. The conical structure can be, for example, the main body of a ship's fairing or other suitable components. The fairing is located at the stern of the ship and its main body is a conical structure. The conical component includes a plurality of conical outer plates 40. The assembly tool is used to assist in assembling the conical outer plates 40 so that the plurality of conical outer plates 40 are distributed in a circular manner around the axis of the conical component to form the above-mentioned conical component. Figure 1 The assembly tool of this embodiment includes an arc marking tool 10 and an inclination measuring tool 20.

[0098] Reference Figure 2 The arc marking tool 10 includes a first scale 11, a first fixing assembly 12, a bearing assembly 13 and a ruler sleeve assembly 14. A first through hole 1121 is provided at one end of the first scale 11. The bearing assembly 13 is arranged in the first through hole 1121. The first scale 11 can rotate around the axis of the bearing assembly 13. The ruler sleeve assembly 14 is sleeved on the outer circumference of the first scale 11 and can move along the longitudinal direction of the first scale 11. The first fixing assembly 12 is connected to the bearing assembly 13 for installing the arc marking tool 10 to a first preset position.

[0099] Among them, reference Figure 10The first scale 11 is rotated around the axis of the bearing assembly 13 through the bearing assembly 13, and the ruler sleeve assembly 14 is used to install the cutting blade. When the first scale 11 rotates, it can drive the cutting blade to rotate to depict a circular arc. The radius of the depicted circular arc is read using the first scale 11. The radius of the depicted circular arc can be adjusted through the ruler sleeve assembly 14, thereby realizing the depiction of circular arcs of various sizes to match the radius of the lower end of the conical outer plate, which can effectively improve the assembly accuracy and assembly speed of the conical outer plate 40, greatly improve work efficiency, and enable the parameters such as roundness and concentricity of multiple conical outer plates to meet high-precision index requirements, effectively reducing the product rework rate.

[0100] Reference Figure 11 The inclination measuring tool 20 includes a second scale 21, a first rotating rod assembly 22, a second rotating rod assembly 23 and a second fixing assembly 24. A second through hole 211 is provided in the second scale 21. The second through hole 211 extends along the longitudinal direction of the second scale 21. The first rotating rod assembly 22 and the second rotating rod assembly 23 are slidably connected to the second scale 21 through the second through hole 211. The second fixing assembly 24 is connected to the second scale 21 for installing the inclination measuring tool 20 to the second preset position.

[0101] Among them, the second fixing component 24 is used to install the second scale 21 to the second preset position of the conical outer plate 40. The second scale 21 can be used to obtain the longitudinal spacing distance between the first rotating rod component 22 and the second rotating rod component 23, and according to the vertical distance between the first rotating rod component 22 and the second rotating rod component 23, the current inclination of the conical outer plate 40 can be calculated. By adjusting the inclination of the conical outer plate to meet the preset theoretical inclination, the inclination of the conical outer plate 40 is quickly calibrated, which effectively improves the assembly efficiency and assembly accuracy of the conical outer plate 40, so that the parameters such as the inclination of multiple conical outer plates 40 can meet the high-precision index requirements, and effectively reduces the product rework rate.

[0102] In this embodiment, refer to Figure 2 and Figure 3The first scale 11 includes a main body 111 and a tip section 112. The main body 111 is provided with first scale lines for measuring distances along the longitudinal direction of the main body 111. The tip section 112 is connected to one longitudinal end of the main body 111. A first through hole 1121 is located within the tip section 112 and extends through the tip section 112 along its thickness. When viewed from above along the axial direction of the first through hole 1121, the center of the first through hole 1121 is the zero point of the first scale lines. The upper side of the tip section 112 is provided with a crosshair passing through the center of the first through hole 1121. The upper side of the tip section 112 is the surface of the tip section along one side of the thickness of the tip section, through which the first scale lines are read. Optionally, the center intersection of the crosshairs on the tip section is the center of the first through hole 1121, and one segment of the crosshairs is collinear with the first scale lines, while the other segment is perpendicular to the first scale lines.

[0103] By setting the center of the first through hole 1121 as the zero point of the first scale line, the reading of the first scale 11 can be matched with the radius of the arc line obtained during use. By controlling the position of the cross line on the end head 112, it is helpful to achieve accurate positioning of the bearing assembly 13 during the assembly process of the arc marking tool 10, thereby improving the measurement accuracy of the arc marking tool 10 and ensuring the construction accuracy of the assembly link of the conical outer plate 40.

[0104] In an optional embodiment, the main scale body 111 has an elongated structure, and the end portion 112 has a polygonal structure, a circular structure, or other suitable structure. Specifically, the end portion 112 can be, for example, a polygonal structure, and the dimension of the end portion 112 along the width direction of the main scale body 111 is greater than the width of the main scale body 111, and the width direction, thickness direction, and longitudinal direction of the main scale body 111 are perpendicular to each other.

[0105] In this embodiment, refer to Figures 3 to 6 The bearing assembly 13 includes a ball bearing 131, a first fastening portion 133, and a plurality of arc-shaped plates 132. The ball bearing 131 is disposed within the first through hole 1121 and is coaxial with the first through hole 1121. A crosshair is provided on the upper side of the ball bearing 131. The crosshair on the ball bearing 131 passes through the center of the first through hole 1121. The ball bearing 131 also includes a third through hole 1311 coaxial with the first through hole. Optionally, the crosshairs on the ball bearing 131 intersect with the center of the first through hole 1121, and the crosshairs on the ball bearing 131 are aligned with the crosshairs on the end portion 112. Preferably, the ball bearing 131 is a high-precision device that prevents it from shaking inward or outward during rotation. By providing the ball bearing 131, the first scale 11 can be rotated about the axis of the first through hole while maintaining the relative position of the ball bearing 131 as a whole, thereby improving construction accuracy.

[0106] Reference Figure 3 and Figure 4 Several curved plates 132 are sequentially arranged around the axis of the third through hole 1311 and connected to the ball bearing 131. A crosshair passing through the center of the first through hole 1121 is provided on the surface of the curved plates 132 along one side of the first scale in the thickness direction.
