Description

Technical Field

[0001] This invention relates to the field of turbocharger technology, and more particularly to a rotary positioning ring mounting mechanism. Background Technology

[0002] As a crucial component of high-end automotive engines, the turbocharger's primary function is to increase the intake air density, resulting in more complete fuel combustion and increased engine power. A common type of turbocharger is the exhaust gas bypass turbocharger, which uses the high-temperature exhaust gases from the engine to drive the turbocharger's turbine, which in turn powers the compressor. Because the amount of exhaust gas emitted by a car engine varies at different engine speeds, the required intake air volume also varies. This type of turbocharger typically incorporates an actuator in the turbine housing to control the exhaust gas bypass valve, thus regulating the amount of exhaust gas entering the turbine.

[0003] In common actuator structures, the connecting rods are connected and then positioned by a locating ring. To compensate for the assembly gaps during the connecting rod assembly process and to reduce noise during the connecting rod's movement, a locating ring is added between the tie rod and the rocker arm. This locating ring is a simple steel wire shape with elastic tension. However, this locating ring needs to be manually opened during installation, which is difficult.

[0004] Therefore, a rotary positioning ring installation mechanism was developed to solve the above problems. Summary of the Invention

[0005] This invention proposes a rotary positioning ring installation mechanism to solve the problem of inconvenient positioning ring installation in the prior art.

The second sliding shaft and the second working shaft are perpendicularly connected to the middle part and the other end of the second rod body, respectively. The second sliding shaft is slidably connected to the second sliding groove. The second working shaft passes through the central through hole of the fixed ring.

[0007] Furthermore, a first rotating shaft is vertically connected to the middle of the first rod, and a first pin hole is provided on the fixing ring. The first rotating shaft is rotatably connected to the first pin hole.

[0008] Furthermore, one end of the second rod is vertically connected to a second rotating shaft, and a second pin hole is provided on the rotating ring, wherein the second rotating shaft is rotatably connected to the second pin hole.

[0024] like Figure 1 and Figure 2 As shown, a rotary positioning ring mounting mechanism includes a rotating frame 1, a fixed base 2, a first pull rod 3, and a second pull rod 4.

[0025] like Figure 3 As shown, the rotating frame 1 includes a rotating ring 1-1 and a first sliding groove 1-2, the first sliding groove 1-2 being laterally formed on the rotating ring 1-1; like Figure 4 As shown, the fixed base 2 includes a fixed ring 2-1 and a second sliding groove 2-4. The rotating ring 1-1 is nested just outside the fixed ring 2-1, and the second sliding groove 2-4 is opened laterally on the fixed ring 2-1. like Figure 5 As shown, the first pull rod 3 includes a first rod body 3-1, a first working shaft 3-4, and a first sliding shaft 3-2. The middle part of the first rod body 3-1 is rotatably connected to the fixed ring 2-1. The first sliding shaft 3-2 and the first working shaft 3-4 are respectively perpendicularly connected to the two ends of the first rod body 3-1. The first sliding shaft 3-2 is slidably connected to the first sliding groove 1-2. The first working shaft 3-4 passes through the central through hole of the fixed ring 2-1. like Figure 6 As shown, the second pull rod 4 includes a second rod body 4-1, a second working shaft 4-4, and a second sliding shaft 4-3. One end of the second rod body 4-1 is rotatably connected to the rotating ring 1-1. The second sliding shaft 4-3 and the second working shaft 4-4 are perpendicularly connected to the middle and the other end of the second rod body 4-1, respectively. The second sliding shaft 4-3 is slidably connected to the second sliding groove 2-4. The second working shaft 4-4 passes through the central through hole of the fixed ring 2-1.

[0026] like Figure 1 and Figure 5 As shown, in some implementations, a first rotating shaft 3-3 is vertically connected to the middle of the first rod 3-1, and a first pin hole 2-3 is provided on the fixing ring 2-1. The first rotating shaft 3-3 is rotatably connected to the first pin hole 2-3.

[0027] like Figure 2 and Figure 6 As shown, in some implementations, one end of the second rod 4-1 is vertically connected to a second rotating shaft 4-2, and a second pin hole 1-3 is provided on the rotating ring 1-1. The second rotating shaft 4-2 and the second pin hole 1-3 are rotatably connected.

[0028] like Figure 2 As shown, in some implementations, the fixing base 2 is provided with a fixing connector, which is used to fix the fixing ring 2-1 to the external structure.

[0029] like Figure 5 and Figure 6 As shown, in some implementations, the first working shaft 3-4 and the second working shaft 4-4 both pass through the top surface of the fixed ring 2-1 from the bottom surface of the fixed ring 2-1, and the fixed connecting member includes a fixing rod 2-2 vertically disposed on the bottom surfaces of both sides of the fixed ring 2-1.

[0033] like Figure 7As shown in (a), (b), and (c), the fixed base 2 is first fixed. When the rotating frame 1 rotates around the fixed base 2, the first pull rod 3 rotates on the fixed base 2 and slides on the rotating frame 1; the second pull rod 4 rotates on the rotating frame 1 and slides on the fixed base 2. When installing the positioning ring 5, the free-state positioning ring 5 is first placed in a rotary positioning ring installation mechanism. The two sides of the opening of the positioning ring 5 contact the first working shaft 3-4 and the second working shaft 4-4 respectively. When the rotating frame 1 rotates, the first working shaft 3-4 and the second working shaft 4-4 expand outwards, increasing the opening of the positioning ring 5. Then, the positioning ring 5 is placed in the installation position, and the rotating frame 1 is released to complete the installation of the positioning ring 5.

[0034] like Figure 8 As shown in (d), (e), and (f), the positioning ring 5 is gradually installed between the pull rod and the rocker arm. The removal of the positioning ring 5 follows the same procedure as described above.
