Description

Technical Field

[0001] This utility model relates to the field of turbocharger mechanism technology, and in particular to a quick-disassembly and assembly structure for turbocharger mechanisms. Background Technology

[0002] The turbocharger core is the main component of a turbocharger, typically consisting of a turbine shaft, turbine impeller, compressor impeller, and bearing system. These components together form a high-speed rotating rotor system, which operates in extremely harsh environments, needing to withstand high temperatures, high pressures, and the enormous centrifugal forces generated by high-speed rotation.

[0003] In existing turbocharger mechanisms, the self-locking nut at the end of the turbine shaft needs to be removed during disassembly and assembly. However, if the turbocharger mechanism is exposed to a humid environment during operation, the self-locking nut and the threaded structure of the turbine shaft are prone to corrosion and are difficult to disassemble and assemble, thus affecting the quick disassembly and assembly of the turbocharger mechanism. To address this, we propose a quick disassembly and assembly structure for the turbocharger mechanism. Utility Model Content

[0004] The main objective of this invention is to provide a quick-disassembly and assembly structure for a turbocharger mechanism. By improving the turbine shaft used for mounting the mechanism body, a disassembly mechanism is designed for screwing in the self-locking nut. The threaded patch of the disassembly mechanism, in conjunction with an L-shaped guide and a fork filler plate, assembles into a detachable threaded head at the threaded notch. When the threaded head rusts, the fork filler plate can be removed, creating a gap between the threaded notch and the threaded patch. This facilitates quick disassembly of the self-locking nut of the mechanism body for rapid replacement of rusted components. This effectively solves the problem of difficult disassembly and assembly due to rust on existing self-locking nuts and turbine shaft thread structures, significantly improving the disassembly and assembly efficiency of the turbocharger mechanism in complex operating environments and effectively addressing the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A quick-release mechanism for a turbocharger core includes a core body, a turbine shaft, and a self-locking nut. The turbine shaft extends through the core body, which also includes a disassembly mechanism. The disassembly mechanism includes a threaded notch post, a threaded patch, a fork filler plate, a hole-aligning plate, a threaded bolt, a sealing ring, and a sealing swivel. A threaded notch post is integrally formed at the shaft end of the turbine shaft extending from the core body, and an L-shaped guide groove for engaging an L-shaped guide bar is provided at the notch post. The L-shaped guide bar is integrally formed on the lower surface of the threaded patch, and a self-locking nut is screwed onto the outer side of the threaded patch and the threaded notch post. A fork filler plate, which is sleeved on the outer side of the L-shaped guide bar, is embedded between the threaded patch and the threaded notch post. A hole-aligning plate is integrally formed on the outer side of the fork filler plate, and the hole-aligning plate is locked with the threaded notch post and the threaded patch by a threaded bolt.

[0007] Furthermore, the surface of the threaded patch has a through hole, and a threaded hole is provided at the threaded notch on one side of the through hole. A threaded bolt is screwed between the hole of the matching plate and the through hole and the threaded hole.

[0008] By adopting the above technical solution, the threaded plug can be screwed into the through hole of the threaded plate and the through hole of the threaded patch after passing through the plate hole and the through hole of the threaded patch, thereby locking the threaded patch at the threaded patch.

[0009] Furthermore, a bottom thread hole is provided at the threaded notch below the threaded patch, and a head thread bolt is screwed between the bottom thread hole and the hole of the matching plate.

[0010] By adopting the above technical solution, the threaded bolt can be screwed into the bottom thread hole of the threaded pin after passing through the hole of the disc.

[0011] Furthermore, the head of the bolt rod of the bolt is threaded, and grooves for securing the sealing ring and sealing strip are sequentially opened on the outer side of the bolt rod away from its own thread.

[0012] By adopting the above technical solution, the threaded head of the threaded bolt can be deeply screwed into the threaded structure of the threaded hole and the bottom threaded hole. Then, the bolt body of the threaded bolt can obtain a contact sealing position in the hole with the help of the sealing ring and sealing strip, so as to prevent the threaded structure of the threaded bolt from being affected by moisture and water and rusting.

[0013] Furthermore, the length of the L-shaped guide groove is greater than the length of the L-shaped guide bar, and the vertical strip of the L-shaped guide bar extends upwards out of the vertical groove opening of the L-shaped guide groove;

[0014] By adopting the above technical solution, the L-shaped guide bar can be smoothly installed in the L-shaped guide groove.

[0015] Furthermore, the vertical strip of the L-shaped guide bar is inserted into the fork groove opened on the surface of the fork filling plate, and the fork filling plate is assembled with the threaded notch post and the threaded patch to form a threaded post head;

[0016] By adopting the above technical solution, the fork filler plate can be clamped and positioned on the outside of the vertical strip of the L-shaped guide bar using the fork groove. Then, the fork filler plate is assembled with the threaded notch post and the threaded patch to form a threaded post head that can be screwed on with a self-locking nut.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention improves the turbine shaft used for mounting the turbocharger body by setting up a disassembly mechanism for screwing on the self-locking nut. The threaded patch of the disassembly mechanism, together with the L-shaped guide and the fork filler plate, is assembled into a detachable threaded head at the threaded notch post. When the threaded head is rusted, the fork filler plate can be removed, creating a gap between the threaded notch post and the threaded patch. This facilitates quick disassembly of the self-locking nut of the turbocharger body for rapid replacement and installation of rusted components. It effectively solves the problem of difficult disassembly and installation of existing self-locking nuts and turbine shaft thread structures due to rust, and significantly improves the disassembly and installation efficiency of the turbocharger body in complex operating environments.

[0019] Furthermore, the fork filler plate's hole plate, threaded missing column, and threaded patch are screwed and locked together using a threaded bolt. A sealing ring and sealing strip are also provided at the threaded bolt for waterproofing during screwing in, effectively ensuring the assembly firmness and disassembly reliability of the threaded column head, and ensuring the stability of the turbocharger mechanism during operation.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-3As shown, a quick-release structure for a turbocharger mechanism includes a mechanism body 1, a turbine shaft 2, and a self-locking nut 3. The turbine shaft 2 extends through the interior of the mechanism body 1. The mechanism also includes a disassembly mechanism 4, which comprises a threaded notch post 5, a threaded patch block 6, a fork filler plate 9, a hole-aligning disc 10, a threaded bolt 11, a sealing ring 12, and a sealing swivel strip 13. The turbine shaft 2 has a threaded notch post 5 integrally formed at the point where it extends through the mechanism body 1, and the notch post 5... An L-shaped guide groove 7 for mounting an L-shaped guide bar 8 is provided on the surface. The L-shaped guide bar 8 is integrally formed on the lower surface of the threaded patch 6. A self-locking nut 3 is screwed onto the outside of the threaded patch 6 and the threaded missing post 5. A fork-filling plate 9 is embedded between the threaded patch 6 and the threaded missing post 5 and is sleeved on the outside of the L-shaped guide bar 8. A hole-matching plate 10 is integrally formed on the outside of the fork-filling plate 9. The hole-matching plate 10 is locked to the threaded missing post 5 and the threaded patch 6 by a threaded bolt 11.

[0026] The threaded patch 6 has a through hole 14 on its surface and a threaded hole 16 is provided at the threaded notch post 5 on one side of the through hole 14. A threaded bolt 11 is screwed between the disc hole of the matching plate 10 and the through hole 14 and the threaded hole 16.

[0027] By adopting the above technical solution, the threaded bolt 11 can pass through the disc hole of the hole plate 10 and the through hole 14 of the threaded patch 6 and then be screwed into the through hole 14 of the threaded missing post 5 for installation, thereby locking the threaded patch 6 at the threaded missing post 5.

[0028] Among them, a bottom thread hole 15 is provided at the threaded missing surface post 5 below the threaded patch 6, and a head thread bolt 11 is screwed between the bottom thread hole 15 and the disc hole of the matching disc 10.

[0029] By adopting the above technical solution, the threaded bolt 11 can pass through the disc hole of the hole plate 10 and be screwed into the bottom thread hole 15 of the threaded pin 5 for spinning.

[0030] The bolt head of the bolt 11 is threaded, and grooves for mounting and bonding sealing ring 12 and sealing swivel strip 13 are sequentially opened on the outer side of the bolt head away from its own thread.

[0031] By adopting the above technical solution, the threaded head of the threaded bolt 11 can be deeply screwed into the threaded structure of the threaded hole 16 and the bottom threaded hole 15. Then, the bolt body of the threaded bolt 11 can obtain a contact sealing position in the hole with the help of the sealing ring 12 and the sealing strip 13, so as to prevent the threaded structure of the threaded bolt 11 from being affected by moisture and water and rusting.

[0032] Wherein, the length of the groove cavity of the L-shaped guide groove 7 is greater than the length of the strip of the L-shaped guide bar 8, and the vertical strip of the L-shaped guide bar 8 extends upward out of the vertical groove opening of the L-shaped guide groove 7;

[0033] By adopting the above technical solution, the L-shaped guide bar 8 can be smoothly installed in the L-shaped guide groove 7.

[0034] The vertical strip of the L-shaped guide bar 8 is inserted into the fork groove on the surface of the fork filling plate 9, and the fork filling plate 9 is assembled with the threaded notch post 5 and the threaded patch 6 to form a threaded post head.

[0035] By adopting the above technical solution, the fork filling plate 9 can be clamped and positioned on the outside of the vertical strip of the L-shaped guide bar 8 using the fork groove. Then, the fork filling plate 9 is assembled with the threaded notch post 5 and the threaded patch block 6 to form a threaded post head that can be screwed onto the self-locking nut 3.

[0036] It should be noted that this utility model is a quick-assembly and disassembly structure for a turbocharger mechanism. By modifying the turbine shaft 2 used for mounting the mechanism body 1, a disassembly mechanism 4 is installed. After the threaded notch 5 of the disassembly mechanism 4 is placed at the original threaded shaft of the turbine shaft 2, the threaded patch 6 is guided and secured at the L-shaped guide groove 7 at the notch 5 by an L-shaped guide bar 8. Then, a fork-type plate 9 is used to secure it to the outside of the L-shaped guide bar 8, allowing the fork-type plate 9, the threaded notch 5, and the threaded patch 6 to assemble into a threaded head that can be screwed onto a self-locking nut 3 for locking and installing the mechanism. Finally, the threaded head... The bolt 11 passes through the disc hole of the hole plate 10 and is screwed into the threaded hole 16 of the threaded pin 5 along the through hole 14 of the threaded patch 6. At the same time, another set of threaded bolts 11 are screwed into the bottom thread hole 15 of the threaded pin 5 to ensure the assembly of the threaded pin head. The threaded head of the threaded bolt 11 can be deeply screwed into the threaded structure of the threaded hole 16 and the bottom thread hole 15. Then the bolt body of the threaded bolt 11 can obtain the contact sealing position in the hole with the help of the sealing ring 12 and the sealing strip 13 to prevent the threaded structure of the threaded bolt 11 from being affected by moisture and water and rusting.

[0037] When the threaded post head is not rusted, the self-locking nut 3 can be rotated directly for quick disassembly and assembly. However, when the threaded post head is rusted due to a humid environment and wear, the threaded bolt 11 can be unscrewed and the fork filler plate 9 can be removed. At this time, the L-shaped guide bar 8 of the threaded patch 6 can descend to contact the bottom of the L-shaped guide groove 7, so that there is a loose position between the threaded patch 6 and the threaded missing post 5, which makes it convenient to unscrew the self-locking nut 3 to disassemble the movement body 1.

[0038] It should be noted that this utility model is a quick disassembly and assembly structure for a turbocharger mechanism. All components in this utility model are known to those skilled in the art, and their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
