Description

Technical Field

[0001] The utility model relates to the technical field of engine cylinder sleeves, in particular to an engine cylinder sleeve removal device. Background Art

[0002] The engine cylinder liner is an important component in the internal combustion engine, used to contain the high temperature and high pressure gas formed by the reciprocating motion of the piston. It is usually made of wear-resistant alloy cast iron or aluminum alloy, with good thermal conductivity and wear resistance. The design and material selection of the engine cylinder liner have a great influence on the engine performance and life. They are usually designed according to the engine type and purpose, and play a vital role in engine maintenance and care.

[0003] The conventional method for disassembling the cylinder liner of an engine is that a worker manually hits the cylinder liner from four directions with a crowbar to loosen the edge of the cylinder liner and then remove the cylinder liner. This manual disassembly method may fail to lift the cylinder liner at best, or directly damage the cylinder liner at worst. The worker will consume too much physical strength during long-term work, and may easily hurt his fingers, thus causing safety accidents and low work efficiency. Utility Model Content

[0023] Specifically, the fixing cylinder 10 is placed into the cylinder sleeve by holding the handle 3, and the turntable 12 is driven to rotate by the output end of the motor 11. The turntable 12 is then pushed by the connecting plate 13 to push the clamping plate 14, so that the clamping plate 14 is completely close to the inner wall of the cylinder sleeve, thereby firmly fixing the fixing cylinder 10 on the cylinder sleeve. At the same time, the output end of the hydraulic cylinder 4 pushes the push plate 5, and then drives the connecting cylinder 6 to push the fixing cylinder 10, which enables the first plug ring 7 and the slider 8 to slide inside the mounting cylinder 1, and limits the position of the connecting cylinder 6 and the fixing cylinder 10. This can quickly and easily remove the engine cylinder sleeve without the need for cumbersome disassembly steps. At the same time, it not only improves the convenience of operation, but also greatly saves time and energy for disassembling the engine cylinder sleeve, thereby improving work efficiency.

[0024] Reference Figure 1 and Figure 3 The mounting assembly includes a mounting ring 16, the interior of the mounting ring 16 is fixedly connected to the outer wall of the fixed cylinder 10, and the outer wall of the connecting cylinder 6 is slidably connected to the interior of the mounting ring 16; the interior of the mounting ring 16 is fixedly connected to a connecting frame 17, and the outer wall of the connecting frame 17 is rotatably connected to a rotating shaft 18; the outer wall of the rotating shaft 18 is fixedly connected to a top plate 20, and a spring 21 is arranged inside the mounting ring 16; one end of the spring 21 is fixedly connected to the interior of the mounting ring 16, and the other end of the spring 21 is fixedly connected to the outer wall of the top plate 20; the outer wall of the top plate 20 is fixedly connected to a button 22, and the outer wall of the button 22 is slidably connected to the interior of the mounting ring 16; the outer wall of the rotating shaft 18 is fixedly connected to an insert plate 19; the outer wall of the insert plate 19 penetrates into the interior of the mounting ring 16, and the outer wall of the insert plate 19 is slidably connected to the interior of the connecting cylinder 6;

[0025] Specifically, when the device needs to be disassembled, by pressing the button 22, the top plate 20 compresses the spring 21, and at the same time the top plate 20 drives the rotating shaft 18 to rotate, thereby pushing the plug plate 19 to tilt up, which makes the plug plate 19 slide out of the connecting tube 6, and the connecting tube 6 slides out of the mounting ring 16, so that the connecting tube 6 and the fixed tube 10 can be disassembled, and necessary repairs and maintenance can be carried out, thereby improving the maintenance convenience of the device, extending its service life, and ensuring the stability and reliability of the device during long-term use.

[0026] Working principle: When the cylinder sleeve needs to be disassembled, the fixing cylinder 10 is placed into the cylinder sleeve by holding the handle 3, and then the output end of the motor 11 can drive the turntable 12 to rotate, so that the turntable 12 can push the clamping plate 14 through the connecting plate 13 until the clamping plate 14 is completely close to the inner wall of the cylinder sleeve, thereby fixing the fixing cylinder 10 and the cylinder sleeve. At the same time, the output end of the hydraulic cylinder 4 pushes the push plate 5 and then drives the connecting cylinder 6 to push the fixing cylinder 10, so that the first plug ring 7 and the slider 8 can slide inside the installation cylinder 1, thereby connecting the connecting cylinder 6 and the fixing cylinder. The position of 10 is limited, so that the engine cylinder liner can be quickly taken out, which improves the practicability of the device. When the device needs to be disassembled, the top plate 20 is driven to compress the spring 21 by pressing the button 22. At the same time, the top plate 20 can also drive the rotating shaft 18 to rotate, thereby driving the plug plate 19 to tilt up, until the plug plate 19 slides out of the inside of the connecting tube 6, and then the connecting tube 6 slides out of the mounting ring 16, so as to achieve the effect of disassembling and repairing the connecting tube 6 and the fixing tube 10, which improves the convenience of the device and prolongs the service life of the device.
