[0002] Marine diesel engine end cap components consist of end caps, connecting flanges, door frame flanges, shaft head connecting seats, connecting seat plates, and other parts. Different marine diesel engine models adopt different designs for end cap components, and their external dimensions, part composition, part assembly dimensions, and assembly position relationships often vary. Due to the production characteristics of small batches, multiple models, and centralized production of marine diesel engines, two assembly methods are currently commonly used: ① single model single tooling assembly method; ② platform scribing assembly method.

[0003] However, existing assembly methods all have their own insurmountable problems and shortcomings. Single-model single-tool assembly method: low tooling utilization rate and high space occupation rate, resulting in high overall production cost. Platform marking assembly method: in the case of small batch and centralized production, the work of marking, positioning and installation are repetitive, resulting in low production efficiency and high risk of assembly errors. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a template tooling positioning device for assembling marine diesel engine sealing plates. This device has the advantages of reducing tooling production costs, improving tooling utilization, increasing production efficiency, and reducing assembly dimensional defects, thus solving the problems mentioned in the background art.

[0006] Preferably, a cavity is provided on one side of the template platform, and a drawer is movably installed inside the cavity.

[0007] Preferably, the upper surface of the template platform is provided with millimeter scale lines, which are opened on two adjacent sides of the upper surface of the template platform.

[0008] Specifically, the star-shaped holes are star-shaped and are evenly and densely distributed on the upper surface of the template platform.

[0009] Preferably, the right-angle positioning block is L-shaped, and an adjustment groove is provided in the middle of the right-angle positioning block. The adjustment groove is a long strip through groove.

[0010] Preferably, the connecting seat is a rice-shaped column that matches the shape of the rice-shaped hole and is fitted into the rice-shaped hole.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The positioning device for the marine diesel engine sealing plate assembly uses a template platform, a star-shaped hole and positioning module, a right-angle positioning block and a conical top block to achieve the positioning and assembly of various models and specifications of marine diesel engine sealing plates. This improves production efficiency, installation quality, reduces production costs, increases tooling utilization, and reduces the problem of poor assembly dimensions. It fundamentally gets rid of the drawbacks of single model single tooling and platform marking assembly method.

[0013] 2. The successful development of the assembly process method for positioning and installing sealing plates of various marine diesel engine models using a template platform with positioning modules, right-angle positioning blocks, and conical top blocks has improved production efficiency, reduced the risk of dimensional deviations in assembly, improved product quality, increased tooling utilization, greatly reduced the number of tooling, improved site utilization, and reduced the overall production cost of assembly.

A cavity 13 is formed on one side of the template platform 1, and a drawer 14 is movably installed inside the cavity 13. The cavity 13 and the drawer 14 increase the device's storage capacity, facilitating the storage of small parts and tooling such as positioning modules 5, right-angle positioning blocks 9, and conical top blocks 11, preventing loss. Millimeter graduation lines 3 are provided on the upper surface of the template platform 1, located on adjacent sides. These graduation lines 3 are used for module positioning, installation, and dimensional inspection, and facilitate accurate positioning of the positioning modules 5. A star-shaped hole 2 is formed on the upper side of the template platform 1. The star-shaped holes 2 are evenly and densely distributed on the upper surface of the template platform 1, used for installing various functional positioning modules 5. The star-shaped holes 2 and the star-shaped connecting seats 4 ensure a more secure installation. To facilitate fixing the angle of the positioning module 5 and prevent it from rotating, a connecting seat 4 is fitted inside the star-shaped hole 2. The connecting seat 4 is a star-shaped column with the same shape as the star-shaped hole 2 and is fitted into the star-shaped hole 2. The connecting seat 4 is used in conjunction with the star-shaped shape of the template platform 1 to increase the positioning effect of the positioning module 5. The positioning module 5 is fixedly installed on the upper end of the connecting seat 4. A sliding groove 6 is opened above the positioning module 5. A bolt 7 is movably installed inside the sliding groove 6. A nut 8 is movably installed on the upper end of the bolt 7. A right-angle positioning block 9 is movably installed below the nut 8. The right-angle positioning block 9 is L-shaped. An adjustment groove 10 is opened in the middle of the right-angle positioning block 9. The adjustment groove 10 is a long strip through groove. The adjustment groove 10 facilitates the adjustment of the installation position of the right-angle positioning block 9 and the fine adjustment of the extension length of the right-angle positioning block 9. A conical top block mounting hole 12 is opened at the front end of the positioning module 5. A conical top block 11 is movably installed inside the conical top block mounting hole 12.

[0022] Working principle: When in use, the template platform 1 is designed according to the maximum external dimensions and weight of the diesel engine sealing plate of each model. The template platform 1 has a star-shaped hole 2 for installing positioning modules 5 for various functions. Millimeter scale lines 3 are distributed on the edge of the platform for positioning, installation and dimensional inspection of the positioning modules 5.

[0023] Design of positioning module 5, right-angle positioning block 9 and conical top block 11: Based on the structural and dimensional characteristics of the sealing plate components of various diesel engine models, a set of positioning modules 5 suitable for the installation of sealing plates of various diesel engines was designed. It is composed of positioning modules 5 of various specifications, right-angle positioning blocks 9 and conical top blocks 11, and is positioned and installed on the cross-shaped holes 2 in the template platform 1.
