Description

Technical Field

[0001] This application relates to the field of shipbuilding technology, and in particular to an assembly tooling and assembly method for a tapered outer plate. Background Technology

[0002] In the shipbuilding industry, a fairing is typically installed on the outer edge of the propeller at the stern to increase propeller thrust. This fairing effectively increases water velocity, thereby enhancing propeller efficiency and significantly impacting the overall performance of the ship. The main body plate of the fairing employs a conical structure, which requires extremely stringent design specifications regarding the roundness, taper, and concentricity of its ends during manufacturing. Due to the large size of the conical fairing's outer plate, it generally requires assembly from multiple thick plates. Only after meeting all high-precision requirements can subsequent welding processes be carried out to ensure the final quality of the fairing.

[0003] Currently, during the fairing manufacturing stage, the precision control tools used by construction workers are relatively rudimentary, mainly relying on measuring tapes and plumb bobs to measure and position the outer plates that make up the fairing. However, in actual operation, multiple people need to work together to complete the measurement of the fairing outer plates. This not only increases the input of human resources, but also easily leads to poor measurement accuracy due to coordination errors between different personnel. Furthermore, it is difficult to meet the high precision requirements in the complex splicing and assembly of fairing outer plates, making it difficult to effectively guarantee the construction precision of the entire fairing manufacturing process. This results in frequent product rework, which not only prolongs the shipbuilding cycle, but also increases production costs, and has a significant negative impact on the progress and economic benefits of the entire shipbuilding project.

[0064] As described above, compared with the prior art, the assembly fixture and assembly method for the tapered outer plate provided in this application have at least the following advantages:

[0065] When assembling tapered outer plates using a circular arc scribing fixture, a cutting blade is installed via a ruler sleeve assembly. A bearing assembly rotates the first scale, which in turn rotates the cutting blade to scribble a circular arc. The radius of the arc can be read using the first scale, and the ruler sleeve assembly is used to adjust the radius of the arc so that the scribed arc can accurately match the radius of the tapered outer plate. This effectively improves the assembly efficiency and accuracy of the tapered outer plates, ensuring that parameters such as roundness and concentricity of each tapered outer plate meet high-precision requirements and reducing product rework rates.

[0066] When assembling a tapered outer plate using an inclination measuring fixture, a second scale is installed on the tapered outer plate at a second preset position via a second fixing component. The distance between the first and second rotating rod components along the longitudinal direction of the second scale is measured using the second scale. Based on the vertical distance between the first and second rotating rod components, the current inclination of the tapered outer plate can be calculated. By adjusting the inclination of the tapered outer plate to meet the preset theoretical inclination, the inclination of the tapered outer plate can be quickly calibrated, effectively improving the assembly efficiency and accuracy of the tapered outer plate. This ensures that the inclination and other parameters of each tapered outer plate meet high-precision requirements, reducing product rework rate.

[0067] Therefore, the assembly tooling and assembly method of this application can quickly achieve precise positioning of the conical outer plate during the manufacturing process of the conical component, so that parameters such as roundness, taper, and concentricity can meet the requirements of various accuracy indicators. Moreover, the operation is simple, no special measuring tools are required, production costs are saved, work efficiency is improved, and the problem of poor construction accuracy in the existing fairing manufacturing process is effectively overcome, thus having high industrial application value.

[0096] Example 1

[0097] This embodiment provides an assembly fixture for a conical outer plate, used to assist in the fabrication of a conical component. The conical component can be, for example, the main body of a ship's fairing or other suitable parts. The fairing is located at the stern of the ship, and its main body has a conical structure. The conical component includes several conical outer plates 40. The assembly fixture assists in assembling the conical outer plates 40, such that the several conical outer plates 40 are arranged sequentially in a ring around the axis of the conical component to form the aforementioned conical component. (Refer to...) Figure 1 The assembly fixture in this embodiment includes an arc scribing fixture 10 and an inclination measuring fixture 20.

[0098] Reference Figure 2 The arc scribing fixture 10 includes a first scale 11, a first fixing component 12, a bearing component 13, and a ruler sleeve component 14. One end of the first scale 11 is provided with a first through hole 1121. The bearing component 13 is arranged in the first through hole 1121. The first scale 11 can rotate around the axis of the bearing component 13. The ruler sleeve component 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 component 12 is connected to the bearing component 13 and is used to install the arc scribing fixture 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 via the bearing assembly 13. The scale 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 mark the arc. The radius of the marked arc can be read using the first scale 11. The radius of the marked arc can be adjusted through the scale sleeve assembly 14, thereby realizing the marking of arcs of various sizes to match the radius of the lower end of the tapered outer plate. This can effectively improve the assembly accuracy and assembly speed of the tapered outer plate 40, greatly improve work efficiency, and enable the roundness, concentricity and other parameters of multiple tapered outer plates to meet the high-precision index requirements, effectively reducing the product rework rate.

[0100] Reference Figure 11 The tilt measuring fixture 20 includes a second scale 21, a first rotating rod assembly 22, a second rotating rod assembly 23, and a second fixing assembly 24. The second scale 21 has a second through hole 211 extending longitudinally. 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 and is used to install the tilt measuring fixture 20 to a second preset position.

[0101] Specifically, the second scale 21 is installed to the second preset position of the conical outer plate 40 using the second fixing component 24. The interval distance between the first rotating rod component 22 and the second rotating rod component 23 along the longitudinal direction of the second scale 21 can be obtained through the second scale 21. Based on the vertical distance between the first rotating rod component 22 and the second rotating rod component 23, the current tilt angle of the conical outer plate 40 can be calculated. By adjusting the tilt angle of the conical outer plate to meet the preset theoretical tilt angle, the tilt angle of the conical outer plate 40 can be quickly calibrated, which effectively improves the assembly efficiency and assembly accuracy of the conical outer plate 40. This allows the tilt angle and other parameters of multiple conical outer plates 40 to meet high-precision index requirements, effectively reducing the product rework rate.

[0102] In this embodiment, refer to Figure 2 and Figure 3The first scale 11 includes a main scale body 111 and an end head 112. The main scale body 111 has a first scale line for measuring distances along its longitudinal direction. The end head 112 is connected to one end of the main scale body 111 along its longitudinal direction. A first through hole 1121 is located inside the end head 112 and extends through it along its thickness direction. 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 line. A crosshair passing through the center of the first through hole 1121 is provided on the upper surface of the end head 112. The upper surface of the end head 112 is a surface along its thickness direction, through which the first scale line can be read. Optionally, the center intersection of the crosshairs on the end head is the center of the first through hole 1121, and one segment of the crosshairs is collinear with the first scale line, while the other segment is perpendicular to the first scale line.

[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 during use. By controlling the position of the cross line on the end head 112, it is helpful to achieve precise positioning of the bearing assembly 13 during the assembly process of the arc scribing fixture 10, thereby improving the measurement accuracy of the arc scribing fixture 10 and ensuring the construction accuracy of the assembly process of the tapered outer plate 40.

[0104] In an optional embodiment, the main scale body 111 is a long strip structure, and the end head 112 is a polygonal structure, a circular structure, or other suitable structure. Specifically, the end head 112 can be a polygonal structure, and the dimension of the end head 112 along the width direction of the main scale body 111 is greater than the width of the main scale body 111. 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 part 133, and several arc-shaped plates 132. The ball bearing 131 is disposed within and coaxially with the first through hole 1121. A crosshair is provided on the upper side of the ball bearing 131, passing through the center of the first through hole 1121. A third through hole 1311, coaxial with the first through hole, is also provided in the ball bearing 131. Optionally, the crosshair on the ball bearing 131 intersects with the center of the first through hole 1121 as its central point, and the crosshair on the ball bearing 131 is aligned with the crosshair on the end head 112. Preferably, the ball bearing 131 is a high-precision device to prevent internal / external wobbling during rotation. By setting the ball bearing 131, the first scale 11 can rotate around the axis of the first through hole, while keeping the overall relative position of the ball bearing 131 unchanged, thus improving construction accuracy.

[0106] Reference Figure 3 and Figure 4 Several arc-shaped 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 one side of the arc-shaped plate 132 along the thickness direction of the first scale, extending to the inner side of the arc-shaped plate 132, and the crosshair on the arc-shaped plate 132 is aligned with the crosshair on the ball bearing 131. By setting the arc-shaped plate 132 and providing the crosshair on it, the adjustment and installation of the bearing assembly 13 can be facilitated, and the installation and use of the entire arc scribing fixture 10 can also be convenient.
