Description

Technical Field

[0001] The utility model relates to a connection structure of a turbocharger, in particular to a connection structure of an air intake shell of a turbocharger, and belongs to the technical field of turbochargers. Background Art

[0002] As a key component of modern engines, turbochargers utilize the inertial momentum of exhaust gas to propel the turbine wheel within the turbine chamber, which in turn drives the compressor wheel, compressing the air entering the engine and increasing the engine's air intake and power. The intake housing, a key component of a turbocharger, has a direct impact on its performance and reliability due to its connection structure.

[0003] The existing turbocharger intake housing connection structure is relatively simple, usually using flanges and bolts and other fasteners to fix the intake housing and the connecting housing. Although this connection method has high connection strength for the intake housing, the disassembly and installation require the use of special tools, which makes the operation of personnel have certain limitations. In addition, the bolts will rust due to long-term use under the influence of humid air, and the rusted bolts will cause great trouble to the disassembly work. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a turbocharger intake housing connection structure with high connection strength and easy disassembly and assembly.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A turbocharger intake casing connection structure includes a turbocharger body, an intake casing body and an exhaust casing body are provided on the turbocharger body, the intake casing body and the exhaust casing body are respectively connected to a connecting casing body and an exhaust pipe, the connecting casing body is provided with a tool-free disassembly structure, the tool-free disassembly structure includes a connecting head fixedly mounted on one end of the connecting casing body, a groove adapted to the connecting head is provided on the intake casing body, a plurality of mounting holes are provided on the connecting head, a spring is fixedly mounted inside the mounting hole, a clamping block is fixedly mounted on the top of the spring, a plurality of clamping holes for use with the clamping block are provided at one end of the intake casing body, and the shape of the clamping block is set to be a trapezoid with an inclined surface at one end.

[0007] Furthermore, a plurality of fixing brackets are fixedly mounted on the air intake housing body, a push block is movably mounted on the fixing bracket, a limit block is fixedly mounted on the top of the push block, and a limit hole adapted to the limit block is opened on one side of the block.

[0008] Furthermore, threaded holes are provided on the fixing frame and the pushing block, and a bolt body is movably installed inside the threaded hole.

[0009] Furthermore, a wear-resistant coating is provided on the surface of the threaded hole and the inner side of the groove.

[0010] Furthermore, a dust cover is provided on one side of the turbocharger body, a first magnetic ring is fixedly mounted on one side of the dust cover, and a second magnetic ring magnetically connected to the first magnetic ring is fixedly mounted on the turbocharger body.

[0011] Furthermore, a flange body is fixedly mounted on the exhaust shell body and the exhaust pipe, a plurality of connection holes are opened on the flange body, an insertion rod is movably mounted inside the connection hole, and a fixing block is fixedly mounted on one end of the insertion rod.

[0012] Furthermore, a plurality of grip rods are fixedly mounted on the other end of the insertion rod.

[0013] The beneficial effects of the present invention are:

[0014] The present application changes the traditional method of fixing the air intake shell and the connecting shell with fasteners such as flanges and bolts by setting a tool-free disassembly structure, so that the connection between the air intake shell body and the connecting shell body not only has high connection strength, but also can be disassembled and installed without tools, making operation simpler and more efficient for personnel; during operation, the connecting head at one end of the connecting shell body is first aligned with the groove opened on the air intake shell body and inserted. During the insertion process of the connecting head, the clamping block will touch one end of the air intake shell body. Therefore, when the connecting head is pushed into the groove again, the clamping block will be squeezed and contracted into the inside of the mounting hole. When the clamping block moves to the position of the clamping hole, the clamping block pops out and engages with the inside of the clamping hole under the elastic action of the spring, so that the connecting shell body and the air intake shell body can be connected without tools; due to the trapezoidal shape of the clamping block, the clamping block can only be squeezed and contracted when it is inserted into the groove. When the connecting head is pulled out, the personnel must manually press the clamping block to contract, thereby avoiding the situation where the connecting head is loosened due to external vibration, and preventing the bolts from rusting when using bolts to connect, which makes disassembly cumbersome for personnel.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be described clearly and completely below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-6The shown structure is a turbocharger intake casing connection structure, which includes a turbocharger body 1, an intake casing body 2 and an exhaust casing body 3 are provided on the turbocharger body 1, the intake casing body 2 and the exhaust casing body 3 are respectively connected to a connecting casing body 4 and an exhaust pipe 5, and a tool-free disassembly structure 6 is provided on the connecting casing body 4; the tool-free disassembly structure 6 includes a connecting head 7 fixedly installed at one end of the connecting casing body 4, a groove 8 adapted to the connecting head 7 is provided on the intake casing body 2, a plurality of mounting holes 9 are provided on the connecting head 7, a spring 10 is fixedly installed inside the mounting hole 9, a clamping block 11 is fixedly installed on the top of the spring 10, a plurality of clamping holes 12 for use with the clamping block 11 are provided at one end of the intake casing body 2, and the shape of the clamping block 11 is set to a trapezoid with an inclined surface at one end. By setting the tool-free disassembly structure 6, the traditional method of fixing the air intake shell and the connecting shell with fasteners such as flanges and bolts is changed, so that the connection between the air intake shell body 2 and the connecting shell body 4 is not only strong in connection strength, but also can be disassembled and assembled without tools, making the operation simple and efficient. During the operation, the connecting head 7 at one end of the connecting shell body 4 is first aligned with the groove 8 opened on the air intake shell body 2 and inserted. During the insertion process, the block 11 of the connecting head 7 will touch one end of the air intake shell body 2, so the connecting head 7 is stuck in the groove 8 when it is pushed into the groove again. The block 11 will be squeezed and shrunk into the inside of the mounting hole 9. When the block 11 moves to the position of the clamping hole 12, the block 11 pops out under the elastic action of the spring 10 and is clamped into the inside of the clamping hole 12. Therefore, the connecting shell body 4 and the air intake shell body 2 can be connected without tools. Due to the trapezoidal shape of the block 11, the block 11 can only be squeezed and shrunk when it is inserted into the groove 8. When the connector 7 is pulled out, the person must manually press the block 11 to shrink it, thereby avoiding the situation where the connector 7 is loosened due to external vibration.

[0024] like Figure 3 As shown, a plurality of fixing frames 13 are fixedly installed on the air intake housing body 2, and a push block 14 is movably installed on the fixing frame 13. A limit block 15 is fixedly installed on the top of the push block 14, and a limit hole 16 adapted to the limit block 15 is opened on one side of the clamping block 11; when the clamping block 11 is engaged in the inside of the clamping hole 12, the push block 14 is pushed to drive the limit block 15 to move so that the limit block 15 is inserted into the inside of the limit hole 16, which can fix the clamping block 11 and prevent the clamping block 11 from being accidentally hit and contracted into the inside of the mounting hole 9, causing the connector 7 to fall off from the inside of the groove 8.

[0025] like Figure 3 As shown, threaded holes 17 are provided on the fixing frame 13 and the push block 14, and a bolt body 18 is movably installed inside the threaded hole 17; the bolt body 18 is inserted into the threaded hole 17 to fix the push block 14 on the fixing frame 13, which can prevent the push block 14 from sliding during use of the limit block 15 and affecting the fixation of the clamping block 11.

[0026] like Figure 1 and Figure 4 As shown, the surface of the threaded hole 17 and the inner side of the groove 8 are both provided with a wear-resistant coating 19. The provision of the wear-resistant coating 19 can improve the wear resistance of the connector 7 and the air intake shell body 2, and avoid friction damage to the connector 7 and the air intake shell body 2 caused by multiple disassembly.

[0027] like Figure 5 As shown, a dust cover 20 is provided on one side of the turbocharger body 1, and a first magnetic ring 21 is fixedly mounted on one side of the dust cover 20, and a second magnetic ring 22 is fixedly mounted on the turbocharger body 1 and is magnetically connected to the first magnetic ring 21; after the first magnetic ring 21 and the second magnetic ring 22 are attracted to each other, the dust cover 20 can be fixed on the turbocharger body 1, and the dust cover 20 can prevent dust from entering the interior of the turbocharger body 1 and causing it to malfunction. Due to the characteristics of the first magnetic ring 21 and the second magnetic ring 22, the dust cover 20 can be disassembled without tools, which facilitates the disassembly and replacement of the dust cover 20.

[0028] like Figure 6 As shown, the exhaust shell body 3 and the exhaust pipe 5 are fixedly installed with a flange body 23, and a plurality of connecting holes 24 are opened on the flange body 23. The interior of the connecting hole 24 is movably installed with an insert rod 25, and one end of the insert rod 25 is fixedly installed with a fixing block 26; the insert rod 25 is inserted into the interior of the connecting hole 24 to connect the two flange bodies 23, and the insert rod 25 is rotated so that the angle of the fixing block 26 is perpendicular to the connecting hole 24, so that the exhaust pipe 5 can be fixed on the exhaust shell body 3, and the insert rod 25 is rotated so that the angle of the fixing block 26 is consistent with the connecting hole 24, and the insert rod 25 can be removed, which is convenient for disassembling the exhaust pipe 5 and cleaning the interior of the exhaust shell body 3.

[0029] like Figure 6 As shown, a plurality of grips 27 are fixedly installed at the other end of the insertion rod 25. The setting of the grips 27 can increase the friction force at the other end of the insertion rod 25, so that the hands of the personnel are not likely to slip when rotating the insertion rod 25, thereby facilitating the installation and disassembly of the insertion rod 25.

[0030] The working process of the turbocharger intake housing connection structure provided in this embodiment is as follows:

[0031] First, align the connecting head 7 at one end of the connecting shell body 4 with the groove 8 provided on the air intake shell body 2 and insert it. During the insertion process of the connecting head 7, the clamping block 11 will touch one end of the air intake shell body 2. Therefore, when the connecting head 7 is pushed into the groove 8 again, the clamping block 11 will be squeezed and shrunk into the inside of the mounting hole 9. When the clamping block 11 moves to the position of the clamping hole 12, the clamping block 11 pops out and engages with the inside of the clamping hole 12 under the elastic action of the spring 10. Therefore, the connecting shell body 4 and the air intake shell body 2 can be connected without tools; due to the trapezoidal shape of the clamping block 11, the clamping block 11 can only be squeezed and shrunk when it is inserted into the groove 8. When the connecting head 7 is pulled out, the clamping block 11 must be manually pressed to shrink, thereby avoiding the situation where the connecting head 7 is loosened due to external vibration.
