Description

Technical Field

[0001] The present invention relates to the technical field of new material surface treatment, in particular to a device and method for cleaning and maintaining the surface coating of a universal joint shaft made of a high-temperature resistant alloy. Background Art

[0002] With the rapid development of aerospace, high-end equipment manufacturing and new energy industries, high-temperature resistant rare metal universal joints (such as titanium alloy, tungsten-molybdenum alloy or nickel-based high-temperature alloy) are widely used in extreme working environments such as aircraft engines, gas turbines, and high-precision mechanical transmission systems due to their excellent strength, corrosion resistance and high-temperature stability.

[0003] However, such universal joints are susceptible to the formation of dense oxide layers, carbon deposits, or sintered contaminants on their surfaces when subjected to long-term exposure to high temperatures, high pressures, and corrosive media. For example, titanium alloy universal joints will develop a TiO2 oxide film when operating above 800°C, while nickel-based alloys are susceptible to carbon deposits in high-temperature gas environments. These coatings not only increase friction and wear on transmission components but also reduce heat transfer efficiency and even cause fatigue cracks, seriously impacting equipment life and operational safety.

[0004] The current cleaning method generally involves manual or robotic polishing, which can easily damage precision mating surfaces and makes it difficult to clean hidden areas such as grooves and hinges. Normal temperature water flow is ineffective in removing high-temperature sintering pollutants, and fixed nozzles cannot cover the multi-angle protrusions of the universal joint.

[0005] A search revealed a publication number CN220836886U that discloses a shaft processing cleaning device, comprising a pad, a table fixed to the top of which is a cleaning pipe slidably mounted via a double-arm support structure. The interior of the cleaning pipe is provided with a multi-point internal spray structure for spraying cleaning fluid, and a plurality of scrubbing members are evenly spaced within the cleaning pipe; a T-shaped seat and a right-angle assembly are fixed to one side of the top of the pad. This utility model employs an enclosed, enclosed spraying structure that effectively controls the spraying and wiping process of the cleaning fluid, preventing liquid from splashing onto the surrounding environment or onto the operator, thereby improving work safety. Furthermore, the enclosed structure ensures that the cleaning fluid or cleaning solvent remains on the shaft surface longer, allowing it to better dissolve, decompose, or flush dirt.

[0006] Currently, when cleaning the shaft, the nozzle is installed in a fixed manner, which makes it difficult to clean multiple joints and raised parts, especially some complex universal joint raised lateral positions, which often have notches located inside the side, making it difficult to quickly clean the direct injection nozzle. Summary of the Invention

[0016] Preferably, a sprocket is fixedly mounted on one end of the bidirectional screw, and the two sprockets are meshed with the same chain.

[0017] The present invention also provides a method for using a device for cleaning and maintaining the surface coating of a high-temperature resistant alloy universal joint shaft, which is used for the above-mentioned device for cleaning the surface coating of the universal joint shaft, comprising the following steps: S1: Place the universal joint to be cleaned between two annular gas injection boxes and start the high-pressure air pumps at both ends. The high-pressure air pumps inject high-pressure gas into the annular gas injection boxes through the connecting pipes, thereby pushing the piston ring to move. The piston ring squeezes the gas in the annular gas injection box and introduces it into the corresponding cylinder through the air pipe. The piston of the cylinder drives the clamping plate to move, thereby clamping and fixing the universal joint and ensuring that the universal joint is in the center of the annular gas injection box. S2: The water pump injects clean water into the annular water injection box through the water inlet pipe. The water in the annular water injection box is interconnected with the annular connecting hole through multiple water guide holes, so that it can be injected into the annular rotating box. The water flow in the annular rotating box is introduced into the water injection cylinder through the conduit and sprayed out through the water spray elbow, thereby acting on the universal shaft. At the same time, one end of the water spray elbow is offset by forty-five degrees from the plane of the annular rotating box, so that the water spray elbow pushes the annular rotating box to rotate under the reaction force when spraying water. The annular rotating box drives multiple water spray elbows to spray water uniformly and comprehensively to various positions of the universal shaft for cleaning. At the same time, the fan-shaped hole on the transmission gear is slidably connected with the driving screw, so that the transmission gear and the driving screw can form a limit, so that the annular rotating box can drive the driving screw to rotate when it rotates through the transmission gear. The driving screw is threadedly connected to the annular water injection box, thereby driving the annular water injection box to move; S3: When the annular water injection box moves, the annular water injection box drives the two gear rods to move. When the gear rod moves to the L-shaped push rod position, it pushes the gear rod in the opposite direction of the L-shaped push rod, thereby driving the gear rod to change its angle. The gear rod drives the L-shaped force rod and the water spray elbow to rotate. When the L-shaped force rod rotates to the other side of the top spring, the top spring pushes the L-shaped force rod, thereby acting on the water spray elbow, causing the water spray elbow to rotate ninety degrees, thereby changing the water spray direction, thereby driving the annular rotating box to rotate in the opposite direction, and then driving the screw rod to be threadedly connected to the annular water injection box, thereby driving the annular water injection box to move in the opposite direction; S4: When the arc pad touches the raised position on the universal joint, the raised position will push the arc pad and the support rod to form an angle change, and the support rod drives the hinge rod to change the angle. The hinge rod is connected to the center rod through rotation, thereby driving the other end of the hinge rod to change the angle in the opposite direction, and then pushing the water injection cylinder to rotate in the opposite direction, so that water can be sprayed on the side of the touched hinge. When the annular water injection box moves in the opposite direction, the water injection cylinder sprays water to clean the other side of the hinge under the action of the support rod. At the same time, the sliding connection between the connecting shaft and the slide rail can buffer the vertical displacement during the angle rotation of the hinge rod, and facilitate the hinge rod to drive the water injection cylinder to form a lateral angle change. The support spring is fixedly connected to the hinge rod and the center rod, thereby positioning the angle of the hinge rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. Dynamic rotary spray system Reaction force drives the circular rotation The water spray elbow is designed with a 45° offset angle and a 30° bend. It uses the reaction force of the water flow to drive the annular rotating box to rotate automatically, and can achieve all-round and dead-angle-free flushing of the universal joint without the need for an additional power device.

[0019] Two-way water spray direction switching Through the mechanical linkage of the L-shaped push rod and the gear lever, combined with the elastic force of the top spring, the water spray elbow can be quickly turned 90 degrees, causing the annular rotating box to rotate in the opposite direction, forming a reciprocating cleaning path and improving coverage uniformity.

[0020] 2. Adaptive raised cleaning mechanism Intelligent steering component When the arc-shaped pad contacts the protrusion of the universal joint, the spray angle of the water spray elbow is automatically adjusted through the linkage structure of the support rod-hinge rod-water injection cylinder to wash the side of the protrusion in a targeted manner.

[0021] Bidirectional cleaning compensation When the annular water injection box moves back and forth, the direction adjustment component dynamically adjusts the water spray direction to ensure that both sides of the protrusion are cleaned, solving the pain point that traditional fixed nozzles are difficult to cover complex structures.

[0022] 3. Integrated transmission and clamping design Gear-screw compound transmission The driving screw slides into engagement with the transmission gear through the sector hole, converting the rotational motion of the annular rotating box into linear movement of the annular water injection box, thereby realizing automatic expansion of the cleaning range with a compact structure and high synchronization.

[0023] Pneumatic adaptive clamping The high-pressure air pump drives the piston ring to uniformly control multiple cylinders, so that the clamping plates can synchronously clamp the universal joint and automatically align it to adapt to different shaft diameters, eliminating the need for manual adjustment.

[0024] 4. Modular water system Annular water distribution structure The coordinated design of the water guide hole and the annular connection hole ensures that the water path is continuously connected when the annular rotating box rotates, avoiding the problem of hose entanglement.

[0025] Pump-conduit graded water injection The graded water delivery path of water pump → annular water injection box → conduit → water injection cylinder, combined with the distributed layout of multiple water spray elbows, achieves efficient water pressure distribution.

[0026] 5. Bidirectional screw coordinated adjustment Sprocket-chain synchronization mechanism A single motor drives the bidirectional screw to rotate synchronously, precisely controlling the distance between the two mounting rings and enabling quick adaptation to universal joints of different lengths, reducing adjustment time.

[0027] 6. Method innovation: dynamic cleaning logic The synergistic effect of steps S3-S4 in switching the water spray direction and identifying and flushing the bumps forms a closed-loop feedback loop, which automatically responds to the surface topography of the universal joint through the mechanical structure, realizing an intelligent process of "identification-adjustment-cleaning" without the need for sensors or electronic control.

The piston ring (85) squeezes the gas in the annular gas injection box (82) and introduces it into the corresponding cylinder (81) through the air pipe (83). The piston of the cylinder (81) drives the clamping plate (84) to move, thereby clamping and fixing the universal joint and ensuring that the universal joint is in the center of the annular gas injection box (82); S2: The water pump (10) injects clean water into the annular water injection box (3) through the water inlet pipe (11). The water in the annular water injection box (3) is connected to the annular connecting hole (15) through a plurality of water guide holes (16), so that it can be injected into the annular rotating box (4). The water flow in the annular rotating box (4) is introduced into the water injection cylinder (51) through the conduit (53) and is sprayed out through the water spray elbow (52), thereby acting on the universal shaft. At the same time, one end of the water spray elbow (52) is offset from the plane of the annular rotating box (4) by 45 degrees, so that when the water spray elbow (52) sprays water, The annular rotating box (4) is driven to rotate under the reaction force, and the annular rotating box (4) drives the plurality of water spraying elbows (52) to evenly and comprehensively spray water to clean each position of the universal shaft.

The shift rod (54) drives the L-shaped force rod (55) and the water spraying elbow (52) to rotate. When the L-shaped force rod (55) rotates to the other side of the top spring (56), the top spring (56) pushes the L-shaped force rod (55) to act on the water spraying elbow (52), causing the water spraying elbow (52) to rotate ninety degrees, thereby being able to change the water spraying direction, thereby driving the annular rotating box (4) to rotate in the opposite direction, and then driving the screw rod (12) to be threadedly connected to the annular water injection box (3), thereby driving the annular water injection box (3) to move in the opposite direction. S4: When the arc pad (63) touches the raised position on the universal shaft, the raised position pushes the arc pad (63) and the support rod (62) to form an angle change, and the support rod (62) drives the hinge rod (65) to change the angle. The hinge rod (65) is connected to the central rod (64) by rotation, thereby driving the other end of the hinge rod (65) to change the angle in the opposite direction, thereby pushing the water injection cylinder (51) to rotate in the opposite direction, so that water can be sprayed sideways on the touched raised position. When the annular water injection box (3) When moving in the reverse direction, the water injection cylinder (51) sprays water to clean the other side of the protrusion under the action of the support rod (62). At the same time, the sliding connection between the connecting shaft and the slide rail can buffer the vertical displacement of the hinge rod (65) when the angle is rotated, and facilitate the hinge rod (65) to drive the water injection cylinder (51) to form a lateral angle change.
