Description

Technical Field

[0001] The utility model relates to the technical field of engine assembly, and more specifically to a split tooling ring for engine hoisting. Background Art

[0002] During engine assembly on a suspended engine pulsation device, the device must be able to rotate around itself. A tooling ring is designed to connect the engine to the device. The suspended pulsation device drives the rolling mechanism on the device, driving the rotation of the tooling and the attached engine. Three key features must be met: 1. The tooling ring must not deform while the engine is suspended; 2. It must be easy to assemble and disassemble, with a well-defined positioning and locking mechanism; and 3. It must be able to support the rolling drive of the clamped engine, featuring a flanged design that allows for roller guidance and tooling ring gripping.

[0003] Existing engine clamping fixtures fall into two categories: 1. Fixed engine fixtures, mounted directly on a multi-degree-of-freedom flip car for engine assembly. These fixtures utilize a notched design for engine mounting and do not support 360-degree rotation of the engine around its axis. 2. Integrated annular fixture rings, while integral and capable of 360-degree rotation, are not easily mounted in the central area of a barrel-shaped engine. Furthermore, if the rings rely solely on their inherent structure for support, they will deform when the engine is suspended, resulting in poor rotation. Utility Model Content

[0004] The purpose of the utility model is to provide a split tooling ring for engine hoisting, which is suitable for installation in the middle area of a barrel-shaped engine, improves work efficiency, effectively prevents the tooling ring from deforming when hanging the engine, and ensures the smoothness of the engine rotation.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A split tooling ring for engine hoisting comprises an upper tooling ring and a lower tooling ring, an upper engine hoist is provided on the inner side of the upper tooling ring, and a lower engine hoist is provided on the inner side of the lower tooling ring, first outer connecting blocks are fixedly connected at both ends of the outer edge of the upper tooling ring, second outer connecting blocks are fixedly connected at both ends of the outer edge of the lower tooling ring, the first outer connecting block and the second outer connecting block are matched with an engaging structure, the first outer connecting block and the second outer connecting block are connected by bolts, the first inner connecting block is fixedly connected to the side surface of the upper tooling ring, the second inner connecting block is fixedly connected to the side surface of the lower tooling ring, and the first inner connecting block and the second inner connecting block are connected by bolts.

[0007] Furthermore, the first external connecting block is provided with a first clamping portion and a first clamping slot, the second external connecting block is provided with a second clamping slot corresponding to the first clamping portion, and a second clamping portion corresponding to the first clamping slot, and the first external connecting block and the second external connecting block are engaged with each other through the first clamping portion, the second clamping slot, the first clamping slot and the second clamping portion.

[0008] Furthermore, the upper engine hanger is connected to the upper tooling ring through threads, and the lower engine hanger is connected to the lower tooling ring through threads.

[0009] Furthermore, the upper engine hanger and the lower engine hanger are both provided with multiple groups.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The utility model adopts a split design, consisting of an upper tool ring and a lower tool ring, which is convenient for installation in the middle area of the engine with a barrel structure, solving the problem that the integrated annular tool ring is inconvenient to install; through the meshing structure of the first outer connecting block and the second outer connecting block, and the bolt connection of the first inner connecting block and the second inner connecting block, the precise positioning and firm locking of the tool ring during the installation process are ensured, and the dual fixing method of the meshing structure and the bolt connection is adopted to ensure that the tool ring does not deform under the load-bearing condition, thereby ensuring the smoothness and stability of the rotation.

[0020] Working principle:

[0021] First, separate the upper ring 1 and the lower ring 2 of the tooling ring and put them on the outside of the engine: splice the upper ring 1 and the lower ring 2 of the tooling ring together through the meshing structure of the first outer connecting block 5 and the second outer connecting block 6. Specifically, the first clamping portion 51 on the first outer connecting block 5 cooperates with the second clamping groove 61 on the second outer connecting block 6, and the first clamping groove 52 on the first outer connecting block 5 cooperates with the second clamping portion 62 on the second outer connecting block 6 to form a stable interlocking structure; the connection between the upper ring 1 and the lower ring 2 of the tooling ring is further strengthened through the bolt connection of the first inner connecting block 7 and the second inner connecting block 8 to ensure the stability of the overall structure; the upper engine hoist 3 and the lower engine hoist 4 are connected to the connection points of the upper and lower parts of the engine respectively to form a complete tooling ring that can be used for engine hoisting and rotation operations.
