Description

Technical Field

[0001] This utility model relates to the field of shipbuilding engineering technology, and in particular to an assembly tooling. Background Technology

[0002] During the installation of the ship's main engine, when installing the main lubricating oil pipe, the rocker arm lubricating oil branch pipe needs to be installed on the upper part of the rocker arm support. Using the flange face of the other end of the branch pipe as a reference, the distance and angle of the main pipe flange are continuously adjusted to locate the main lubricating oil pipe. This method relies on on-site personnel for continuous adjustment and positioning, and has the following problems:

[0003] Low positioning accuracy: Manual operation can easily lead to deviations between the main pipe and branch pipe interfaces, causing flange eye offset.

[0004] Inefficiency: Multiple lubrication systems require frequent tooling changes, extending the assembly cycle.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] like Figures 1 to 3As shown, this embodiment provides an assembly fixture, including a fixture body 1, a first positioning mechanism 21, a second positioning mechanism 31, and a locking device (not shown in the figure).

[0040] The tooling body 1 includes a first positioning section 2 and a second positioning section 3.

[0041] The first positioning mechanism 21 is located in the first positioning section 2 and is used to adjust and position the lubricating oil main pipe in the vertical direction.

[0042] The second positioning mechanism 31 is located in the second positioning section 3 and is used to adjust and position the lubricating oil manifold in the horizontal direction.

[0043] Both the first positioning mechanism 21 and the second positioning mechanism 31 are equipped with locking devices, which are used to quickly fix and release the lubricating oil manifold.

[0044] For example, in this embodiment, the locking device is an M24 bolt. Of course, in some other embodiments, the locking device can be other forms, as long as it can be fixed to the oil manifold.

[0045] It is understood that the assembly fixture provided in this embodiment, by setting a fixture body 1 with a first positioning section 2 and a second positioning section 3, a first positioning mechanism 21 is provided on the first positioning section 2 and a second positioning mechanism 31 is provided on the second positioning section 3, can adjust and position the lubricating oil main pipe in the horizontal and vertical directions respectively, and fix the lubricating oil main pipe by locking device, effectively improving the accuracy of the connection between the lubricating oil main pipe and the lubricating oil branch pipe, and improving the assembly efficiency.

[0046] Specifically, such as Figure 1 As shown, in this embodiment, the first positioning segment 2 and the second positioning segment 3 are hinged. It is understood that, to enhance the adaptability of the tooling to different assembly angle requirements, the first positioning segment 2 and the second positioning segment 3 are not fixedly welded, but are hinged together using components such as hinges. This allows the included angle between the first positioning segment 2 and the second positioning segment 3 to be adjusted according to actual working conditions, no longer limited to a fixed 90 degrees, greatly improving the flexibility of the tooling.

[0047] Furthermore, such as Figure 3 As shown, in this embodiment, an anti-loosening structure 5 is provided at the hinge joint between the first positioning segment 2 and the second positioning segment 3. It can be understood that, in order to ensure that the hinge structure remains stable and does not loosen during assembly after the angle is adjusted, an anti-loosening structure 5 is provided at the hinge joint between the first positioning segment 2 and the second positioning segment 3 to fix the angle between them. The anti-loosening structure 5 can be an anti-loosening nut, a locking pin, or a ratchet mechanism, etc., used to firmly lock the hinge shaft after the angle adjustment is completed.

[0048] Furthermore, in some embodiments, the first positioning mechanism 21 includes a first body 211 and a first positioning plate 212, the first positioning plate 212 being movable along the first body 211, and a locking device disposed on the first positioning plate 212. It is understood that by configuring the first positioning plate 212 to be movable on the first body 211, the locking device on the first positioning plate 212 can move with the first positioning plate 212, thereby enabling the first positioning plate 212 to adapt to lubricating manifolds of different sizes.

[0049] For example, one end of the first body 211 is retractable, and the first positioning plate 212 is disposed at the end of the first body 211 away from the second body 311.

[0050] Of course, in some other embodiments, the first body 211 is provided with a slide rail, and the first positioning plate 212 can move on the slide rail.

[0051] Furthermore, in some embodiments, the second positioning mechanism 31 includes a second body 311 and a second positioning plate 312. The second positioning plate 312 is movable along the second body 311, and a locking device is disposed on the second positioning plate 312. It is understood that the second positioning plate 312 is also movable relative to the second body 311, further improving the applicability of the assembly tooling.

[0052] Since the connecting flanges of some lubricating oil manifolds are not in the same plane, in order to quickly fix such lubricating oil manifolds, in some embodiments, the plane where the first positioning plate 212 is located is perpendicular to the plane where the second positioning plate 312 is located.

[0053] Specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, the end of the second body 311 furthest from the first body 211 is bent at 90 degrees, and the second positioning plate 312 is connected to the end of the second body 311 furthest from the first body 211. It can be understood that this arrangement, by perpendicularly connecting the second positioning plate 312 to the second body 311, allows for the positioning and fixing of the oil manifold on two mutually perpendicular planes, further improving the accuracy of the oil manifold positioning and facilitating the improvement of the accuracy of the connection between the oil manifold and the oil branch pipes.

[0054] Furthermore, in some embodiments, an arc-shaped transition surface 4 is provided at the connection between the first positioning plate 212 and the first main body 211. In some other embodiments, an arc-shaped transition surface 4 is provided at the connection between the second positioning plate 312 and the second main body 311.

[0055] In this embodiment, both the connection between the first positioning plate 212 and the first main body 211, and the connection between the second positioning plate 312 and the second main body 311, are provided with an arc-shaped transition surface 4 with a radius of 40mm. It can be understood that by providing the arc-shaped transition surface 4, stress concentration at the connection between the first positioning plate 212 and the first main body 211, and at the connection between the second positioning plate 312 and the second main body 311, can be reduced. Furthermore, by dispersing stress, structural strength can be improved. Simultaneously, the connection between the first positioning plate 212 and the first main body 211, and the connection between the second positioning plate 312 and the second main body 311, becomes smoother, improving both appearance and feel, and facilitating use by operators.

[0056] Furthermore, in some embodiments, both the first positioning mechanism 21 and the second positioning mechanism 31 are provided with threaded interfaces 6.

[0057] For example, in this embodiment, the first positioning plate 212 and the second positioning plate 312 are provided with M24 threaded interfaces 6. This is a standard thread size, which has sufficient connection strength and can directly cooperate with the M24 bolt of the locking device to achieve quick fixing and release.

[0058] In this embodiment, a metal protective layer is provided on the tooling body 1. It is understood that, in order to improve the corrosion resistance and wear resistance of the tooling in harsh industrial environments (such as the high humidity and high salt spray environment of a ship's engine room) and extend its service life, a metal protective layer is provided on the surface of the tooling body 1. This protective layer is preferably a hard chrome layer formed by an electroplating process.

[0059] Furthermore, in this embodiment, the first positioning segment 2 and the second positioning segment 3 are detachably connected. It is understood that, for ease of transportation, storage, and modular assembly and maintenance of the tooling, the first positioning segment 2 and the second positioning segment 3 are detachably connected.

[0060] For example, in this embodiment, the reliable connection and quick disassembly of the first positioning segment 2 and the second positioning segment 3 are achieved by means of positioning pins and fastening bolts.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
