Description

Technical Field

[0001] This invention relates to the field of turbocharger technology, and more particularly to a gripping 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, after the connecting rods are connected, they are limited by a positioning ring. In order to compensate for the assembly gap during the connecting rod mating process and reduce the noise of the connecting rod during movement, a positioning ring is added between the tie rod and the rocker arm. This positioning ring is a simple steel wire shape with elastic tension. It needs to be manually opened during installation, which makes installation difficult.

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

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

[0006] The present invention achieves the above objectives through the following technical solutions: This invention provides a gripping positioning ring mounting mechanism, comprising: The upper rocker arm includes an upper arm body and an upper sliding groove hole. One end of the upper arm body is an upper connecting end and the other end is an upper gripping end. The upper sliding groove hole is inclinedly opened on the upper connecting end. The lower rocker arm includes a lower arm body and a lower sliding groove. One end of the lower arm body is a lower connecting end and the other end is a lower gripping end. The upper connecting end is located above the lower connecting end and is rotatably connected to the lower connecting end. The lower sliding groove is inclinedly opened on the lower connecting end. The upper sliding groove and the lower sliding groove are arranged in an inverted "V" shape. The upper pull rod includes an upper rod body and an upper top rod. One end of the upper rod body is rotatably connected to the top surface of the upper arm body. The upper top rod is vertically downwardly disposed at the other end of the upper rod body, and the bottom end of the upper top rod passes through the sliding groove hole. A pull rod, comprising a lower rod body and a lower push rod, wherein one end of the lower rod body is rotatably connected to the top surface of the lower arm body, and the lower push rod is vertically downwardly disposed at the other end of the lower rod body, and the bottom end of the lower push rod passes through the upper sliding groove hole and the lower arm body in sequence; When the upper and lower gripping ends are subjected to external gripping force, the lower push rod can slide towards the top of the upper sliding groove hole, and the upper push rod can slide towards the top of the lower sliding groove hole.

[0007] Specifically, the upper rocker arm further includes a mounting hole located at the upper connecting end, and the lower rocker arm further includes a mounting shaft located on the top surface of the lower connecting end, the mounting shaft being rotatably connected to the mounting hole.

[0008] Specifically, an upper pin is vertically provided on the inner side of the top surface of the upper arm body, and an upper pin hole is provided at one end of the upper rod body. The upper pin is rotatably connected to the upper pin hole. A lower pin is vertically provided on the top surface of the outer side of the lower arm body, and a lower pin hole is provided at one end of the pull rod. The lower pin is rotatably connected to the lower pin hole.

[0009] Furthermore, an upper groove is provided on the inner side of the upper connecting end. When the upper gripping end and the lower gripping end are subjected to external gripping pressure, the lower pin can enter the upper groove and slide within the upper groove.

[0010] Furthermore, the inner side of the upper connecting end is provided with a relief groove, which is a concave structure provided on the inner side of the upper connecting end.

[0011] Furthermore, the lower connecting end is provided with a lower groove hole, and the bottom end of the lower push rod passes through the upper sliding groove hole and the lower groove hole in sequence.

[0012] Preferably, both the upper rocker arm and the lower rocker arm are plate structures with one end larger than the other.

[0013] Furthermore, a positioning ring is provided on the bottom surface of the lower rocker arm, and the bottom end of the lower sliding groove and the lower push rod are both located within the positioning ring.

[0014] Furthermore, in its natural state, the lower push rod is located at the bottom end of the upper sliding groove hole, and the upper push rod is located at the bottom end of the lower sliding groove hole. When the upper gripping end and the lower gripping end are subjected to external gripping pressure, the lower push rod can slide in the upper sliding groove hole until the top end of the upper sliding groove hole, and the upper push rod can slide in the lower sliding groove hole until the top end of the lower sliding groove hole.

[0015] Furthermore, when the lower push rod slides to the top of the upper sliding groove hole and the upper push rod slides to the top of the lower sliding groove hole, the upper push rod and the lower push rod just push the outer side of the positioning ring to contact the inner surface of the positioning ring enclosure.

[0016] The beneficial effects of this invention are as follows: The grip-type positioning ring installation mechanism proposed in this invention solves the problem of difficult positioning ring installation in the prior art. Operators no longer need to tension the positioning ring by hand. The structure is simple and the installation process is simple, making the positioning ring installation faster and more convenient.

[0024] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, a gripping positioning ring mounting mechanism includes an upper rocker arm 1, a lower rocker arm 2, an upper pull rod 3, and a lower pull rod 4.

[0026] like Figure 1-3 As shown, the upper rocker arm 1 includes an upper arm body 1-0 and an upper sliding groove hole 1-2. One end of the upper arm body 1-0 is an upper connecting end and the other end is an upper gripping end. The upper sliding groove hole 1-2 is inclinedly opened on the upper connecting end. In some embodiments, the upper rocker arm 1 further includes a mounting hole 1-1, which is disposed at the upper connecting end, and the lower rocker arm 2 further includes a mounting shaft 2-1, which is disposed on the top surface of the lower connecting end. The mounting shaft 2-1 is rotatably connected to the mounting hole 1-1, thereby forming a hinge.

[0027] In some embodiments, an upper pin 1-4 is vertically provided on the inner side of the top surface of the upper arm body 1-0, and an upper pin hole 3-2 is provided at one end of the upper rod body 3-0. The upper pin 1-4 is rotatably connected to the upper pin hole 3-2. A lower pin 2-4 is vertically provided on the top surface of the outer side of the lower arm body 2-0, and a lower pin hole 4-2 is provided at one end of the pull rod 4. The lower pin 2-4 is rotatably connected to the lower pin hole 4-2.

[0028] like Figure 1-4 as well as Figure 7 As shown, the lower rocker arm 2 includes a lower arm body 2-0 and a lower sliding groove 2-2. One end of the lower arm body 2-0 is a lower connecting end and the other end is a lower gripping end. The upper connecting end is located above the lower connecting end and is rotatably connected to the lower connecting end. The lower sliding groove 2-2 is inclinedly opened on the lower connecting end. The upper sliding groove 1-2 and the lower sliding groove 2-2 are arranged in an inverted "V" shape. like Figure 1-5 As shown, the upper pull rod 3 includes an upper rod body 3-0 and an upper push rod 3-1. One end of the upper rod body 3-0 is rotatably connected to the top surface of the upper arm body 1-0. The upper push rod 3-1 is vertically downwardly disposed at the other end of the upper rod body 3-0. The bottom end of the upper push rod 3-1 passes through the sliding groove hole 2-2. like Figure 1-6 As shown, the pull rod 4 includes a lower rod body 4-0 and a lower push rod 4-1. One end of the lower rod body 4-0 is rotatably connected to the top surface of the lower arm body 2-0. The lower push rod 4-1 is vertically downwardly disposed at the other end of the lower rod body 4-0. The bottom end of the lower push rod 4-1 passes through the upper sliding groove hole 1-2 and the lower arm body 2-0 in sequence. like Figure 1 as well as Figure 8As shown, in its natural state, the lower push rod 4-1 is located at the bottom end of the upper sliding groove hole 1-2, and the upper push rod 3-1 is located at the bottom end of the lower sliding groove hole 2-2. When the upper and lower gripping ends are subjected to external gripping pressure, the lower push rod 4-1 can slide towards the top end of the upper sliding groove hole 1-2, and the upper push rod 3-1 can slide towards the top end of the lower sliding groove hole 2-2. Preferably, when the lower push rod 4-1 slides to the top end of the upper sliding groove hole 1-2, and the upper push rod 3-1 slides to the top end of the lower sliding groove hole 2-2, the upper push rod 3-1 and the lower push rod 4-1 just push the outer side of the positioning ring to contact the inner surface of the positioning ring enclosure. When the upper gripping end and the lower gripping end are subjected to external gripping force, the lower push rod 4-1 can slide in the upper sliding groove hole 1-2 until the top of the upper sliding groove hole 1-2, and the upper push rod 3-1 can slide in the lower sliding groove hole 2-2 until the top of the lower sliding groove hole 2-2.

[0029] like Figure 1-4 As shown, in some embodiments, the inner side of the upper connecting end is provided with an upper groove 1-3. When the upper gripping end and the lower gripping end are subjected to external gripping pressure, the lower pin 2-4 can enter the upper groove 1-3 and slide within the upper groove 1-3.

[0030] like Figure 3 As shown, in some embodiments, the inner side of the upper connecting end is provided with a relief groove 1-5, and the relief groove 1-5 is a concave structure provided on the inner side of the upper connecting end.

[0031] like Figure 4 and Figure 6 As shown, in some embodiments, the lower connecting end is provided with a lower slot hole 2-3, and the bottom end of the lower push rod 4-1 passes through the upper sliding slot hole 1-2 and the lower slot hole 2-3 in sequence.

[0032] like Figure 3 and Figure 4 As shown, in some embodiments, both the upper rocker arm 1 and the lower rocker arm 2 are plate structures with one end larger than the other.

[0033] like Figure 2 as well as Figure 6-7 As shown, a positioning ring is provided on the bottom surface of the lower rocker arm 2, and the bottom ends of the lower sliding groove 2-2 and the lower top rod 4-1 are both located within the positioning ring.

[0034] In some embodiments, a return spring may be provided between the upper rocker arm 1 and the lower rocker arm 2, thereby allowing the rocker arm to return to the open state.

[0035] When external gripping pressure is received, causing the upper and lower rocker arms to rotate relative to each other, the upper pull rod 3 rotates on the upper rocker arm 1 and slides on the lower rocker arm 2 at the same time; the lower pull rod 4 rotates on the lower rocker arm 2 and slides on the upper rocker arm 1 at the same time.

[0036] like Figure 8 In Figure 8 a, Figure 8 b and Figure 8 As shown in Figure c, during the installation of the positioning ring, first place the free-state positioning ring into the installation mechanism. The two sides of the positioning ring's opening contact the pins of the upper and lower pull rods respectively. When the upper and lower rocker arms are closed, the pins of the upper and lower pull rods expand outwards, increasing the opening of the positioning ring. Then, place the positioning ring in the installation position, and then release the upper and lower rocker arms to complete the positioning ring installation. The process for disassembling the positioning ring is the same as described above.

[0037] This invention employs an upper rocker arm 1, a lower rocker arm 2, an upper pull rod 3, and a lower pull rod 4 to achieve the expansion and installation of the positioning ring. The structure is simple and the operation is convenient. This invention can simultaneously expand both sides of the opening, avoiding deformation of the positioning ring due to force on one side. The mechanism is stable and reliable, achieving a closed expansion action to complete the installation of the positioning ring.

[0038] like Figure 9 In Figure 9 a, Figure 9 b and Figure 9 As shown in Figure c, the mounting ring is first expanded by the present invention and aligned with the connecting rod of the actuator. After the upper and lower rocker arms are released, the mounting ring returns to its original shape, thus realizing the quick installation of the mounting ring onto the connecting rod.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
