Description

Technical Field

[0001] The invention relates to the technical field of equipment, in particular to a detachable impeller of a turbocharger. Background Art

[0002] In the patent application with application announcement number CN218717118U, it includes: a main body module, the main body module includes a base, an annular member fixed at the top of the base, an impeller assembly slidably mounted on the base in an annular array, a rotating member rotatably mounted at the top of the base, a limit block movably arranged in the inner cavity of the rotating member and extending out of the rotating member, a moving member fixed at the top of the limit block and extending out of the rotating member, and a spring connecting the limit block and the inner wall of the rotating member. The advantages are: the impeller assembly is slidably mounted on the base, and the rotating member is rotatably mounted at the top of the base, and a single second oblique groove is opened on the rotating member. When one or more impeller assemblies need to be replaced, the rotating member is rotated, the second oblique groove on the rotating member is rotated to the first oblique groove corresponding to the impeller assembly, and the impeller assembly is slid out through the second oblique groove and slid into a new impeller assembly, so that a single blade can be replaced, thereby avoiding the problem of replacing the entire impeller when a single or multiple blades are damaged, and there is no need to disassemble the impeller, which increases convenience and practical performance.

[0003] In the prior art including the above-mentioned patents, while the impeller blades can be disassembled and assembled, sliding disassembly is the main disassembly and assembly method, or there are other methods such as plug-in. These disassembly and assembly methods all have a problem, that is, gaps are left at the plug-in locations. When the turbine rotates at high speed, these gaps will generate vibrations. Long-term operation vibrations will cause great harm to the impeller blades, and long-term use will also affect the service life of the impeller. Although the effect of being able to replace the blades individually is achieved, the problem of vibrations generated by the gaps is not solved. Summary of the invention

[0004] The problem to be solved by the present invention is that there will be gaps when the detachably assembled impeller blades are fitted in the slide grooves, which will cause the blades to vibrate during use, thus affecting the service life of the blades and causing them to be easily damaged.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a detachable impeller of a turbocharger, comprising a main body, a through groove is provided at the center of the main body, a plurality of slide grooves are provided in a circular array inside the main body, movable grooves are provided inside the main body and on both sides of the slide groove, an auxiliary structure is provided on the outer wall of the main body, and a locking structure is provided inside the main body; The locking structure comprises an arc-shaped plate, telescopic plates are arranged on both sides of the top of the arc-shaped plate, a counterweight block is arranged on the top of the telescopic plate, and both the counterweight block and the telescopic plate are adapted to the movable groove.

[0006] Preferably, limit springs are provided on both sides of the top of the arc-shaped plate, the top of the limit spring is fixedly connected to the inner wall of the main body, and a pull ring is provided at the bottom of the arc-shaped plate.

[0007] Preferably, a limit block is provided on one side of the telescopic plate, the limit block is made of rubber, and one side of the limit block penetrates the groove wall of the movable groove and extends to the interior of the sliding groove.

[0008] Preferably, a slider is slidably provided inside the slide groove, a fan blade is provided on the top of the slider, a cover plate is provided on the front of the main body, and a back plate is provided on the back of the main body.

[0009] Preferably, the front sides of the cover plate and the back plate are penetrated by a plurality of fixing screws in a circular array, the opposite sides of the cover plate and the back plate are provided with protrusions, and the back side of the back plate is provided with a connecting shaft.

[0010] Preferably, an inner cylinder is slidably provided at the center of the main body, and the inner cylinder is used to reinforce the interior of the main body. Grooves are provided on the front and back sides of the inner cylinder, and the grooves are matched with the protrusions.

[0011] Preferably, the auxiliary structure comprises a fixing block, the fixing block is L-shaped, the bottom of the fixing block is in contact with the arc-shaped outer wall of the main body, and a movable plate passes through one side of the fixing block.

[0012] Preferably, the front and back sides of the movable plate are rotatably connected to the fixed block, a pressing plate is fixedly provided on one side of the movable plate, and a buffer spring is fixedly provided on one side of the bottom of the movable plate.

[0013] Preferably, a rotating shaft is provided on the other side of the movable plate, and a rubber pad is rotatably provided on one side of the rotating shaft.

[0014] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) The interior of the main body is provided with a locking structure and a movable groove. The telescopic plate in the locking structure can cooperate with the counterweight block. After the impeller rotates, the counterweight block is driven outward by centrifugal force. The counterweight block will drive the telescopic plate to move and move the limit block on its surface upward to squeeze the slider at the bottom of the blade. The limit block itself is made of rubber material. After being compressed, it can better fit the gap to avoid the gap between the slide rail and the slide groove, which causes the impeller to shake when rotating at high speed and affects its service life. In addition to limiting and reinforcing the blade slider through centrifugal force, the locking structure can also release the lock of the limit block by pulling the pull ring when the blade is damaged in the later stage. The damaged blade can be replaced separately, so that the entire turbine does not need to be replaced after the blade is damaged; (2) An auxiliary structure is also provided on the main body. The auxiliary structure can make the rubber pad firmly clamp the root of the blade through the cooperation between the buffer spring and the movable plate, thereby improving the metal fatigue resistance of the blade and reducing the vibration of the root of the blade. The fixing of the slider can make the two cooperate with each other to improve the stability of the blade as a whole, reduce the metal fatigue caused by vibration, and further extend the service life of the blade. When removing the rubber pad, you only need to press the pressing plate to make the rubber pad detach from the side of the blade, which is simple and convenient. (3) An inner cylinder is also provided inside the main body, and the inner cylinder can be slid and removed. Since the interior of the impeller is hollow, the inner cylinder can not only increase the overall resistance of the main body but also make it more stable during operation. After installation, the pull ring can be further limited to prevent the pull ring from loosening and causing the limit block to move down and affect the blades. The subsequent disassembly will not affect the replacement and maintenance of the blades. The disassembly method is simple and convenient, which is more time-saving and efficient.

[0028] The working principle and use process of the present invention are as follows: when in use, align the blade 2 and the slider 7 at the bottom thereof with the slide groove 11 provided on the main body 3, and after alignment, slide the slider 7 into the slide groove 11. While the slider 7 is slidingly inserted, the pressing plate 404 needs to be pressed. After the pressing plate 404 is subjected to force, the movable plate 403 is driven to rotate with the rotation connection with the fixed block 401 as the center of the circle and stretch the buffer spring 405. At this time, the rubber pad 402 will also move upward and separate from the surface of the blade 2. After the blade 2 is fully inserted, release the pressing plate. The pressure plate 404 and the buffer spring 405 drive the rubber pad 402 to return to the initial position to clamp the bottom of the blade 2 to form an antagonistic force, so that the rubber pad 402 can reduce the vibration generated by the subsequent high-speed rotation of the blade 2.

After all are installed, the cover plate 5 can be fixed to the main body 3 by the fixing screws 6. The convex The blocks can fix the inner cylinder 8. When the main body 3 rotates at a high speed, a large centrifugal force will be generated. The centrifugal force will drive the counterweight block 1002 to move outward, and the counterweight block 1002 drives the telescopic plate 1001 to move outward. The telescopic plate 1001 drives the limit block 1003 to move upward. The limit block 1003 is driven by the centrifugal force to squeeze and fill the gap between the slide groove 11 and the slider 7, so that the connection between the two is tighter, avoiding the generation of gaps that cause the blade 2 to generate greater vibration during rotation. When the blade 2 is released When it is damaged and needs to be replaced, the cover plate 5 can be removed and the inner tube 8 can be slid out. After taking it out, leave a cavity and pull the pull ring 1006 downward. After the pull ring 1006 is subjected to force, it drives the arc plate 1005 to move downward and stretch the limit spring 1004. The arc plate 1005 will drive the telescopic plate 1001 and the limit block 1003 to move downward. After the slider 7 loses the extrusion limit, it can be easily slid out. The user can take out the damaged blade and install a new one and continue to use it without replacing the pig's trotter as a whole.
