Description

Technical Field

[0001] This utility model relates to the field of engine tooling technology, specifically to a cylinder liner spinning tool. Background Technology

[0002] During the operation of large-bore high-speed diesel engines, the engine block requires forced water cooling. To ensure effective and reliable sealing of the engine block's water cooling chamber during operation and leak testing, diesel engine cylinder liners typically employ a double rectangular sealing ring along the lower edge of the outer circle, plus a straight outer circle sealing ring at the upper end. Currently, cylinder liner assembly often uses manual assembly. However, the outer diameter of the cylinder liner is large, and the compression of the rectangular sealing ring is significant. This makes cylinder liner installation difficult, resulting in low assembly efficiency, and the sealing effect of the outer circle sealing ring cannot be guaranteed. Utility Model Content

[0003] To address the shortcomings of difficult cylinder liner assembly, low assembly efficiency, and inability to guarantee sealing performance, this utility model provides a cylinder liner spinning tool, which simplifies cylinder liner assembly, increases assembly efficiency, and ensures sealing performance.

[0004] This utility model provides the following technical solution:

[0005] It includes a bracket, and a pressure block is provided inside the bracket. After the screw passes through the bracket, it can push the pressure block through the bearing positioning structure. The bearing positioning structure includes a bearing seat and a bearing. The bearing is arranged in layers inside the bearing seat. One end of the screw is equipped with a hand-tightening rod, and the other end is inserted into the bearing from the outside of the bearing seat and connected to the bearing through a connecting fixing plate and bolts. The top of the bearing seat is provided with a bearing fixing plate.

[0006] Its further features are:

[0007] The base of the bracket is provided with a threaded channel that allows the positioning screw to pass through.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] By setting up the positioning structure, the bearing housing can be used as a connecting screw and as a push block to push the pressure block. By turning the screw, the pressure block is connected to the cylinder liner and pressed into the machine body, making the cylinder liner assembly simpler, improving assembly efficiency, and ensuring the sealing effect of the cylinder liner.

[0015] This utility model provides, for example Figure 1 A cylinder liner spinning tool is shown, which includes a bracket 1. The bracket 1 is U-shaped when viewed from the front. A pressure block 6 is provided inside the U-shaped bracket 1. A screw 2 passes through the bracket 1 and pushes the pressure block 6 through a bearing positioning structure. The pressure block 6 can be made of PE material. The bearing positioning structure includes a bearing seat 5 and a bearing 3. The bearing 3 is located in the bearing seat 5 and arranged in layers. One end of the screw 2 is equipped with a hand-tightening rod, and the other end is inserted into the bearing 3 from the outside of the bearing seat 5 and connected to the bearing 3 through a connecting fixing plate 8 and bolts. The top of the bearing seat 5 is provided with a bearing fixing plate 4, which is used to limit the bearing 3.

[0016] The base of bracket 1 has a threaded channel that allows the positioning screw 7 to pass through.

[0017] Working principle of this utility model:

[0018] First, the cylinder liner is inserted into the cylinder liner hole of the engine block. The pressure block 6 is placed on the end face of the cylinder liner. The bracket 1 is fixed by inserting the positioning screw 7 into the cylinder head bolt hole of the engine block. Then, the bearing seat 5 is turned by turning the screw 2 to push the pressure block 6 as a pusher. The bearing seat 5 presses the pressure block 6 and the cylinder liner together and slowly presses it into the engine block. The assembly is simple and efficient.
