Description

Technical Field

[0001] The utility model relates to the technical field of intermediate machine lubricating oil nozzle testing, in particular to a quick-detachable nozzle assembly. Background Art

[0002] The intermediate casing is located in the middle of the aircraft engine, between the fan casing and the high-pressure compressor. It is the connection and transition channel of the engine. It is the heart of the engine and the aircraft hoisting, and is the most important load-bearing structure of the engine. The thrust of the engine is mainly transmitted to the aircraft through the intermediate casing, the main thrust mounting section and the auxiliary thrust mounting section. Among them, the intermediate casing bears the overall weight of the engine, vibration, maneuvering overload, and complex forces of four degrees of freedom. Therefore, the intermediate casing needs to be closely integrated with the high-pressure compressor, low-pressure compressor, fulcrum bearing seat and other components, and the research and development requirements are very high.

[0003] The oil nozzle is an essential part in the transmission and lubrication system of aircraft engines. It is used to provide lubricating oil to bearings, gears and dynamic involute splines to achieve the design functions of lubrication and cooling. During the processing and assembly process, the flow rate and flow direction of the oil nozzle need to be checked to verify whether its injection direction, position and flow rate meet its design requirements.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. It should be noted that the threaded connection method is generally used in traditional nozzle assemblies, which is not only easy to cause jamming, but also troublesome during disassembly and installation; 2. When testing the lubricating oil nozzle, the nozzle needs to be replaced for testing. The current disassembly method used for the nozzle cannot complete the disassembly quickly, which will reduce the test efficiency. Utility Model Content

[0005] The purpose of the present utility model is to provide a quick-release nozzle assembly to solve the problem raised in the above background technology. It should be noted that the threaded connection method is generally used in traditional nozzle assemblies, which is not only easy to cause jamming, but also troublesome during disassembly and installation, and the nozzle needs to be replaced for testing when testing the lubricating oil nozzle. When the current disassembly method of the nozzle cannot quickly complete the disassembly, the test efficiency will be reduced. In order to achieve the above purpose, the present utility model provides the following technical solutions: a quick-release nozzle assembly, including a connecting pipe, a nozzle is inserted into the inner wall of the connecting pipe, an oil pipe is provided at the top of the nozzle, a back plate is provided at the bottom end of the oil pipe, four top limit mechanisms are provided on the outer wall of the oil pipe, an oil outlet nozzle is provided at the bottom end of the nozzle, and four plug plates are provided on the outer wall of the connecting pipe.

[0006] Further preferably, two slide grooves are provided on the inner walls on the left and right sides of the connecting pipe.

[0007] Further preferably, elastic clips are slidably connected inside the two slide grooves provided in the connecting pipe.

[0008] Further preferably, a sealing ring is bonded to the top of the abutment plate.

[0009] Further preferably, push rods are provided on both left and right sides of the top of the abutment plate.

[0010] Further preferably, the top limiting mechanism is composed of an L-shaped bottom plate, plug posts and elastic clips, wherein the L-shaped bottom plate is annularly distributed on the outer wall of the oil pipe body, and plug posts are also provided on the bottom wall of the L-shaped bottom plate, and an elastic clip runs horizontally through the top of the plug posts.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, in the traditional nozzle assembly, a threaded connection is generally adopted, which is not only easy to cause jamming, but also troublesome during disassembly and installation. The push rod is inserted into the insertion hole opened at the bottom of the slide groove, and continuously pushes the elastic clip to slide upward along the inner wall of the slide groove until the elastic clip also slides to the bayonet and pops out from the bayonet, thereby completing the installation of the nozzle. When the nozzle needs to be disassembled, the operator only needs to press the elastic clip back from the bayonet to the inside of the slide groove, and then pull out the oil pipe in the reverse direction, thereby driving the back plate and the push rod to slide downward along the slide groove until the entire oil pipe is pulled out from the connecting pipe. The process is convenient and quick, and there will be no jamming.

[0013] In the present invention, the plug post arranged at the bottom wall of the L-shaped base plate will pass through the plug hole opened in the plug plate directly above it. At this time, the elastic clip strip that runs horizontally through the top of the plug post will release the restriction and rebound to its original position, thereby locking the position between the top limit mechanism and the plug plate, and then completing the installation of the entire nozzle assembly. When disassembly is required, the operator only needs to manually press the elastic clip strip to retract it into the inside of the plug post, so that the plug post can be smoothly disengaged from the plug hole opened in the plug plate, and the position lock between the top limit mechanism and the plug plate can be released. At the same time, the elastic clip is also pressed back into the inside of the slide groove, so that the entire oil pipe and components such as the nozzle can be completely separated from the pipe, and the disassembly between the two can be quickly completed.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a quick-detachable nozzle assembly, including a connecting pipe 1, a nozzle 2 is inserted into the inner wall of the connecting pipe 1, an oil pipe 3 is provided at the top of the nozzle 2, a stop plate 4 is provided at the bottom end of the oil pipe 3, four top limit mechanisms 5 are provided on the outer wall of the oil pipe 3, an oil outlet nozzle 6 is provided at the bottom end of the nozzle 2, and four plug plates 7 are provided on the outer wall of the connecting pipe 1.

[0022] In this embodiment, Figure 1 and Figure 2 and Figure 5 As shown, two slide grooves 101 are provided on the inner walls on the left and right sides of the connecting pipe 1; it should be noted that the nozzle is needed when conducting the lubricating oil nozzle test, and the traditional nozzle is generally assembled in a screw connection manner, which is a relatively troublesome assembly method. In the utility model, two slide grooves 101 are provided on the inner walls on the left and right sides of the connecting pipe 1, and the two slide grooves 101 are used to enable the elastic clip 102 provided inside to slide smoothly to the slot provided at the top of the slide groove 101 to complete the snap connection. In this process, it is only necessary to insert the push rod 402 provided on the top of the abutment plate 4 vertically upward from the bottom of the slide groove 101, and the push rod 402 can be used to slide the elastic clip 102 along the inner wall of the slide groove 101 to the slot to complete the snap connection, which is convenient and quick.

[0023] In this embodiment, Figure 2 and Figure 5As shown, the two slide grooves 101 opened in the pipe 1 are slidably connected with elastic clamps 102; it should be noted that the elastic clamps 102 slidably connected in the slide grooves 101 can pop out from the bayonet opening at the top of the slide grooves 101 after the restriction is released. The specific operation is that the operator first inserts the entire nozzle 2 and the oil pipe 3 into the pipe 1. During this period, the abutment plate 4 set at the bottom end of the oil pipe 3 will also approach the bottom of the pipe 1, and the top rod 402 set on the top of the abutment plate 4 can just be inserted vertically upward from the bottom of the slide groove 101, and push the elastic clamps Part 102 slides along the inner wall of the slide groove 101 until the elastic clamp 102 slides to the bayonet. At this time, the top of the elastic clamp 102 is no longer squeezed by the inner wall of the slide groove 101, so it can pop out from the bayonet, and then the entire oil pipe 3 is fixedly clamped inside the connecting pipe 1. When disassembling, the operator only needs to manually press on the top of the elastic clamp 102, press it back from the bayonet to the inside of the slide groove 101, and then pull out the top rod 402 provided on the support plate 4 in the reverse direction, so that the entire oil pipe 3 together with the nozzle 2 can be quickly pulled out of the connecting pipe 1.

[0024] In this embodiment, Figure 3 As shown, a sealing ring 401 is bonded to the top of the plate 4; it should be noted that after the operator inserts the entire nozzle 2 and the oil pipe 3 into the interior of the connecting pipe 1, and pushes the elastic clamp 102 to pop out from the clamping position through the push rod 402 in turn, and locks the position of the entire oil pipe 3 and the connecting pipe 1 through the top limit mechanism 5, the nozzle 2, the oil pipe 3 and the connecting pipe 1 will be assembled into a whole, and then the lubricating oil nozzle test of the intermediate machine can be carried out. During this period, the oil will enter the oil pipe 3 connected to it from the connecting pipe 1, and be input into the nozzle 2 through the internal pipeline opened inside the oil pipe 3, and be sprayed out from the oil outlet 6 provided at the bottom of the nozzle 2. During this process, the oil will flow through the connection between each component and leakage may occur. To avoid this situation, a sealing ring 401 is bonded to the top of the plate 4. The sealing ring 401 just fills the connection gap between the plate 4 and the outlet of the connecting pipe 1, thereby increasing the sealing of the entire nozzle assembly and preventing oil leakage.

[0025] In this embodiment, Figure 3 and Figure 4As shown, both sides of the top of the plate 4 are provided with push rods 402; it should be noted that in the conventional nozzle assembly, a threaded connection is generally adopted, which is not only easy to cause jamming, but also troublesome during disassembly and installation. In the utility model, both sides of the top of the plate 4 are provided with push rods 402, and the push rods 402 can be inserted into the insertion holes opened at the bottom of the slide groove 101. As the plate 4 approaches the bottom of the pipe 1, the push rods 402 will continue to be inserted upwards into the slide groove 101, and during this period, the top of the push rod 402 will be connected to the slide groove 101 by sliding. The elastic clip 102 contacts and continuously pushes the elastic clip 102 to slide upward along the inner wall of the slide groove 101 until the top of the support plate 4 and the bottom of the connecting pipe 1 are tightly attached to each other, and the elastic clip 102 also slides to the bayonet and pops out from the bayonet, thereby completing the installation of the nozzle. When the nozzle needs to be removed, the operator only needs to press the elastic clip 102 back from the bayonet to the inside of the slide groove 101, and then pull out the oil pipe 3 in the reverse direction, thereby driving the support plate 4 and the push rod 402 to slide downward along the slide groove 101 until the entire oil pipe 3 is pulled out of the connecting pipe 1. The process is convenient and fast, and there will be no jamming.

[0026] In this embodiment, Figure 2 and Figure 4 As shown, the top limit mechanism 5 is composed of an L-shaped bottom plate 501, a plug column 502 and an elastic clip strip 503, wherein the L-shaped bottom plate 501 is annularly distributed on the outer wall of the oil pipe 3, and a plug column 502 is also provided on the bottom wall of the L-shaped bottom plate 501, and an elastic clip strip 503 is horizontally penetrated at the top of the plug column 502; it should be noted that when installing the entire nozzle, the operator needs to first insert the push rod 402 into the inside of the slide groove 101, and push the elastic clip 102 to slide upward along the inner wall of the slide groove 101. During this process, the L-shaped bottom plate 501 arranged on the outer wall of the oil pipe 3 will also rise toward the connecting pipe 1, and when the elastic clip 102 slides to the bayonet and pops out from it, the plug column 502 arranged at the bottom wall of the L-shaped bottom plate 501 02 will pass through the socket opened in the plug plate 7 directly above it. At this time, the elastic clip 503 that passes horizontally through the top of the plug column 502 will release the restriction and rebound to its original position, thereby locking the position between the top limit mechanism 5 and the plug plate 7, and then completing the installation of the entire nozzle assembly. When disassembly is required, the operator only needs to manually press the elastic clip 503 to retract it into the inside of the plug column 502, so that the plug column 502 can be smoothly disengaged from the socket opened in the plug plate 7, and the position lock between the top limit mechanism 5 and the plug plate 7 can be released. At the same time, the elastic clip 102 is also pressed back into the inside of the slide groove 101, so that the entire oil pipe 3 and the nozzle 2 and other components can be completely separated from the connecting pipe 1, and the disassembly between the two can be quickly completed.

[0027] The use method and advantages of the utility model: When the quick-release nozzle assembly is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when installing the entire nozzle, the operator first needs to vertically insert the push rod 402 provided on the top of the plate 4 from the bottom of the slide groove 101 upward, and push the elastic clamp 102 to slide upward along the inner wall of the slide groove 101. During this process, the L-shaped bottom plate 501 provided on the outer wall of the oil pipe 3 will also rise toward the connecting pipe 1, and when the elastic clamp 102 slides to the bayonet and pops out from it, the plug column 502 provided on the bottom wall of the L-shaped bottom plate 501 will also pass through the plug hole opened on the plug plate 7 directly above it. At this time, the elastic clip 503 rebounds to its original position, locking the position between the top limit mechanism 5 and the plug plate 7, thereby completing the installation of the entire nozzle assembly. When disassembly is required, the operator only needs to manually press the elastic clip 503 to retract it into the inside of the plug column 502, release the position lock between the top limit mechanism 5 and the plug plate 7, and press the elastic clip 102 back into the inside of the slide groove 101, completely separating the entire oil pipe 3 and the nozzle 2 and other components from the pipe 1, and quickly completing the disassembly between the two.
