Description

Technical Field

[0001] This utility model relates to the field of clamp technology, and in particular to a V-type clamp for turbochargers. Background Technology

[0002] In automotive turbocharging systems, V-clamps play a crucial connecting role. Their primary applications include the turbocharger's turbine outlet, where they securely connect related pipes, and the compressor's inlet and outlet positions. The tightness of these connections is critical to the entire system's functionality. V-clamps are also found at the connections between exhaust manifold sections, helping to ensure stability. Furthermore, V-clamps are essential for the robust and reliable connections at exhaust manifold aftertreatment system joints. These different components all demand extremely high reliability and stability in their connections, ensuring the turbocharging system operates normally and stably, thus providing strong support for the vehicle's overall performance.

[0003] A search revealed Chinese Patent Publication No. CN201884837U, which discloses a V-shaped combination clamp. Its features include a flanged connecting ring with a V-shaped cross-section (smaller at the bottom, larger at the opening), with outward-facing wings on both sides of the V-shaped opening; an open bushing composed of at least two arc-shaped V-shaped groove plates with a smaller at the bottom and larger at the opening, with a gap between adjacent groove plates; a metal band fitted outside the bushing, with a buckle at each end of the metal band; and a "T"-shaped locking device that closes and tightens the two buckles of the metal band. The metal band tightly locks the inclination angle of the inner wall of the bushing to the flared angle of the connected pipe fitting, thereby ensuring a tight fit between the rigid pipe interface end face and the inclined surface of the inner wall of the bushing, achieving safe connection between the two pipe sections. The purpose of ground connection is mainly applicable to the connection of pipe fittings with two flared ends, especially for turbocharger systems, engine exhaust systems, automobile exhaust systems, and thin-walled pipe fittings with flared ends in filter frames. Most of the clamps currently used are fixed. Although this can meet the connection requirements of specific specifications, it lacks flexibility. Once the size or shape of the connector changes, the existing clamps cannot adapt to the new connection requirements. In this case, the corresponding clamps must be remanufactured according to the new connector parameters in order to complete the installation work smoothly.

[0004] Therefore, this utility model proposes a V-type clamp for turbochargers to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the technology of turbocharger V-type clamps, such as poor adaptability to connecting pipes of different sizes or tolerances, weak versatility, insufficient structural rigidity under high temperature and high pressure environments, easy deformation leading to decreased clamping force or sealing failure, this utility model aims to provide a turbocharger V-type clamp with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a V-type clamp for turbochargers, comprising: an outer ring of the clamp, and lugs respectively disposed at both ends of the outer ring of the clamp, wherein one lug is provided with a rotating post, and the lug is provided with a second round hole, and the lug is also provided with a first round hole, and the lug is provided with an external thread, for a bolt to pass through the first round hole and connect with the external thread; and an inner ring slidably connected to the inner wall of the outer ring of the clamp, having a square opening on the inner wall of the outer ring of the clamp, a concave fixing bracket fixedly connected to the bottom of the inner wall of the outer ring of the clamp, and an arc-shaped rod fixed in the concave fixing bracket.

[0007] The inner ring, as a radially movable component, has a protrusion on its outer peripheral wall that slides with the square opening, allowing it to move radially inward or outward when the clamp is tightened or loosened.

[0008] Furthermore, the inner ring forms a sliding connection with the square opening on the inner wall of the outer ring of the clamp through its protrusion, while the concave fixing frame and the arc-shaped rod together form a reinforcing rib structure. The structure is assembled at the bottom of the inner wall of the outer ring of the clamp through a fixed connection, which strengthens and supports the ring structure of the outer ring of the clamp from the inside.

[0009] Preferably, the inner ring structure consists of two circumferentially separated semi-circular inner ring segments, with the ends of the two inner ring segments adjacent to two lugs respectively. This split design allows the two inner ring segments to smoothly and synchronously converge towards the center when the clamp is tightened, so as to fit pipes of different diameters.

[0010] Preferably, in order to further enhance the stability of the structure, multiple concave fixing frames and arc-shaped bars are provided, and these concave fixing frames and arc-shaped bars are arranged at intervals along the circumference of the outer ring of the clamp to form a distributed support network, thereby more evenly dispersing and resisting external pressure and internal locking force, and preventing local deformation.

[0011] Preferably, the connection between the concave fixing frame and the arc-shaped rod is such that the opening of the concave fixing frame faces the radial center of the outer ring of the clamp, and the arc-shaped rod is clamped or welded into the groove of the concave fixing frame. This embedded fixing method has a stable structure and can effectively transfer the bending stiffness of the arc-shaped rod to the outer ring of the clamp.

[0012] Preferably, in order to achieve a good sealing fit with the pipe flange, the inner contact surface of the inner ring is designed as a V-groove structure. The structure can precisely engage with the standard V-shaped flange on the turbocharger pipe flange, generating a strong wedge locking effect to ensure airtightness.

[0013] Preferably, in the connection structure between the lugs, the cooperation between the rotating column and the second round hole constitutes a pivotal connection structure between the two lugs, ensuring the smooth opening and closing movement of the clamp during the locking process.

[0014] Preferably, the locking mechanism has the following structural details: the round hole is a through hole that passes through the lug, allowing the bolt shank to rotatably pass through and thus make threaded connection with the external thread, making operation convenient and reliable.

[0015] Preferably, the sliding fit structure between the inner ring and the outer ring of the clamp is specifically as follows: the square opening is a rectangular groove that penetrates the inner wall of the outer ring of the clamp, and the inner ring is provided with a protrusion that slides with the square opening. This fit between the protrusion and the groove precisely guides and restricts the inner ring to only perform radial reciprocating motion.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, when the clamp is used for connection, it is placed on the interface of two cylindrical components. The rotating pin of the left hanging ear is aligned with the round hole of the right hanging ear and inserted. Then, the bolt on the outer wall of the external thread is rotated and tightened to achieve a tight connection of the components and ensure the stability of the basic connection. The two square openings on the inner wall of its outer ring can flexibly accommodate cylindrical connectors of different sizes, greatly improving the compatibility range.

[0018] 2. In this utility model, multiple arc-shaped rods at the bottom of the inner wall, together with the concave fixing bracket on the outer wall, can effectively resist external pressure, avoid excessive deformation of the clamp, further ensure long-term fixing effect, and meet diverse usage needs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 5 This utility model provides a V-type clamp for turbochargers, which aims to solve the problems of poor adaptability of existing V-type clamps to connecting pipes of different sizes, and insufficient structural rigidity and easy deformation under high temperature and high pressure environments.

[0029] like Figures 1 to 5 As shown, the V-type clamp for turbochargers includes an outer ring 1, with a pair of lugs 2 at each end of the outer ring 1. One lug 2 has a rotating post 3 and a circular hole 7. The rotating post 3 and the circular hole 7 are rotatably connected to form a pivot connection structure between the two lugs 2. The locking structure includes a circular hole 6 on one lug 2 and an external thread 4 on the lug 2. A bolt 5 rotatably passes through the circular hole 6, which serves as a through hole for the lug 2, and is threadedly connected to the external thread 4 to tighten or loosen the two lugs 2. The clamp structure also includes an inner ring 8 that is slidably connected to the inner wall of the outer ring 1.

[0030] To guide and limit the radial sliding stroke of the inner ring 8, a square opening 9 is provided on the inner wall of the outer ring 1 of the clamp, which serves as a rectangular groove penetrating the inner wall of the outer ring 1 of the clamp. The inner ring 8 is provided with a protrusion that slides with the square opening 9. The inner ring 8 is composed of two semi-annular segments separated in the circumferential direction. The ends of the two semi-annular segments are adjacent to the two lugs 2 respectively, and the inner contact surface of the inner ring 8 is a V-groove structure. In order to further enhance the overall structural rigidity of the clamp.

[0031] Multiple concave fixing brackets 10 are fixedly connected to the bottom of the inner wall of the outer ring 1 of the clamp, and an arc-shaped rod 11 is fixed inside the concave fixing bracket 10. The multiple concave fixing brackets 10 and the multiple arc-shaped rods 11 are arranged at intervals along the circumference of the outer ring 1 of the clamp. The opening of the concave fixing bracket 10 faces the radial center of the outer ring 1 of the clamp. The two ends of the arc-shaped rod 11 are clamped or welded into the groove of the concave fixing bracket 10, and work together to resist the deformation of the outer ring 1 of the clamp.

[0032] The technical solution of this embodiment is that an inner ring 8 that can achieve size self-adaptation is provided on the inner wall of the outer ring 1 of the clamp, and a specific sliding connection and limiting fit relationship is formed between the inner ring 8 and the outer ring 1 of the clamp.

[0033] Please refer to Figure 2 The inner ring 8 is composed of two semi-circular segments separated along the circumference. The ends of the two semi-circular segments are adjacent to the two lugs 2, so that they can move towards the center synchronously when the clamp is tightened. The inner ring 8 has a V-shaped groove structure on the inner contact surface facing the pipe to be connected, which is used to cooperate with the V-shaped edge of the pipe flange. The outer peripheral wall of the inner ring 8 also has a protrusion integrally formed with the square opening 9 at the position corresponding to the square opening 9, which is slidably engaged with the square opening 9.

[0034] The inner ring 8 is mounted on the inner wall of the outer ring 1 of the clamp through the protrusion on its outer peripheral wall and is accommodated in the square opening 9, realizing the sliding connection between the inner ring 8 and the outer ring 1 of the clamp. Its function is to be able to shrink inward or expand outward synchronously in the radial direction when the outer ring 1 of the clamp is tightened or loosened.

[0035] Please refer to Figure 3 , Figure 4 and Figure 5 The inner wall of the outer ring 1 of the clamp is provided with a square opening 9, which serves as a rectangular groove penetrating the inner wall of the outer ring 1 of the clamp. In the assembled state, the protrusion of the inner ring 8 slides into the square opening 9 of the outer ring 1 of the clamp. This radial limiting sliding structure of protrusion and groove ensures that the inner ring 8 can only move in the radial direction of the clamp and will not be misaligned or fall off. This ensures that when the clamp is tightened to adapt to different pipe diameters, the two semi-annular segments can stably and synchronously close towards the center, ultimately achieving reliable clamping and sealing of pipes of different sizes.

[0036] Please refer to Figure 3 , Figure 4 and Figure 5The clamp also includes a reinforcing structure composed of concave fixing frames 10 and arc-shaped rods 11. Multiple concave fixing frames 10 and multiple arc-shaped rods 11 are arranged at intervals along the circumference of the outer ring 1 of the clamp. The concave fixing frames 10 are fixedly connected to the bottom of the inner wall of the outer ring 1 of the clamp by welding or integral molding, and the opening of the concave fixing frame 10 faces the radial center of the outer ring 1 of the clamp. The arc-shaped rods 11 are snapped or welded into the groove of the concave fixing frame 10, and their two ends are firmly fixed to the concave fixing frame 10, thereby forming a ring-shaped reinforcing rib skeleton structure on the inner wall of the outer ring 1 of the clamp.

[0037] As another preferred embodiment, in order to optimize the pipe diameter adaptability and sealing performance of the clamp, the inner ring 8 adopts a specific split structure and has a specific mating surface. Specifically, the inner ring 8 is composed of two circumferentially separated semi-annular segments, the ends of the two segments are adjacent to a pair of lugs 2 respectively. At the same time, the inner contact surface of the inner ring 8 is processed into a V-groove structure to fit tightly with the V-shaped section of the turbocharger pipe flange to achieve efficient sealing.

[0038] In another preferred embodiment, in order to ensure reliable pivot rotation and smooth locking operation between the two lugs 2, a rotating pin 3 provided on one lug 2 is rotatably inserted into a circular hole 7 opened on the lug 2 to form a pivot connection structure between the two. At the same time, the circular hole 6 for locking is set as a through hole penetrating the lug 2, allowing the shank of the bolt 5 to rotatably pass through and thus engage with the external thread 4 on the lug 2.

[0039] Working principle: The clamp is placed on the interface of two cylindrical parts that need to be connected. The rotating pin 3 in the left middle lug 2 is aligned with the round hole 7 in the right lug 2 and inserted. The bolt 5 on the outer wall of the external thread 4 is tightened by rotating it, so that the top can tightly connect the two cylinders together. The inner wall of the clamp outer ring 1 is provided with two square openings 9. When the cylindrical connecting body is smaller than the clamp, the bolt 5 is rotated to make the two lugs 2 move closer to the middle. The inner ring 8 of the clamp is attached to the cylindrical connecting body, and the gap between the two inner rings 8 gradually decreases, thereby reducing the wrapping range of the clamp outer ring 1. This allows it to fix different sizes of cylindrical connecting bodies, increasing adaptability. Multiple arc-shaped rods 11 are placed at the bottom of the inner wall of the clamp outer ring 1. The outer wall is fixed to the bottom of the inner wall of the clamp outer ring 1 by multiple concave fixing brackets 10. This can prevent excessive deformation under external pressure, thus preventing the fixing effect from being affected.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make substitutions for some of the technical features. Any modifications, substitutions, or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
