Description

Technical Field

[0001] This invention relates to the field of spraying technology, and in particular to an adaptive painting device and painting method for blade tenons. Background Technology

[0002] With the development of aero-engine technology, the requirements for engine lifespan are becoming increasingly stringent. As a core component of the engine, the quality assurance of each process for the blades plays a crucial role in ensuring the quality of the finished product. Aero-engine rotor blade tenons are generally dovetail-shaped. Before the surface treatment, corrosion, and silver plating of the blade tenons or blade body, a protective paint is applied. Currently, this is mainly done manually. The painting tools used on-site are inefficient, and the painting quality varies from person to person, making it impossible to guarantee consistent quality. Furthermore, due to the very high viscosity of existing paints, it is not possible to use the currently mature automated painting equipment. Therefore, based on the blade painting process, this invention proposes an adaptive painting device for blade tenons to automate the blade painting process, ensuring the quality of the anti-corrosion paint coating, preventing missed areas and spots, improving on-site production efficiency, and shortening the cycle time. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides an adaptive painting device and method for blade tenons. By setting an adaptive moving component and an angle adjustment component, the direction of the felt wheel can be adaptively adjusted according to the shape of the blade tenon, ensuring close contact between the felt wheel and the blade tenon. This provides excellent adaptability to the blade tenon. The adaptive painting of the blade tenon is achieved by the felt wheel being driven by a painting motor, which facilitates the automation of the painting process and reduces the occurrence of missed areas and spots during the painting process, thereby improving painting production efficiency and painting quality.

[0004] The technical solution adopted in this invention is an adaptive painting device for blade tenons, which includes a paint storage unit and an adaptive painting unit. The paint storage unit includes a paint tank, a base, a paint can, and a touch-up pump. The paint tank is mounted on the base, and the paint can and touch-up pump are located in the base. The paint can is connected to the paint inlet of the touch-up pump via a pipeline, and the paint outlet of the touch-up pump is connected to the paint storage tank via a pipeline. The adaptive painting unit is symmetrically arranged on both sides of the paint storage tank, and includes an adaptive moving component, a tilt adjustment component, a painting motor, and a plush wheel. The adaptive moving component is fixed to the paint storage tank by a base plate, and includes a base plate, a guide column, a spring, a support plate, and a moving plate. The first ends of both sides of the base plate are symmetrically provided with guide supports, and the first ends of the guide columns are slidably positioned... On the guide support, the second end of the guide column is connected to the first end of the support plate, and the spring is provided on the guide column. The upper end face of the base plate is provided with a sliding guide rail, and the lower end face of the moving plate is provided with a slider. The moving plate is provided on the base plate, and the slider is slidably provided on the sliding guide rail. The tilt adjustment component is provided on the moving plate, and the painting motor is provided on the upper fixed plate of the tilt adjustment component. The output shaft of the painting motor is connected to the first end of the plush wheel shaft through a coupling, and the second end of the plush wheel shaft is provided with the plush wheel. A horizontal slide is provided above the paint storage unit. Multiple blades are sequentially installed on the blade clamp, and the blade clamp is provided on the horizontal slide. The horizontal slide moves vertically downward and immerses the blade tenon into the paint storage tank. The adaptive painting unit is activated to paint the blade tenon.

[0005] Furthermore, the tilt adjustment assembly includes a lower fixed plate, a rotary damper, and an upper fixed plate. The lower fixed plate is connected to the movable plate, and a lower limit seat is provided at the first end of the lower fixed plate. An upper limit seat is provided at the first end of the upper fixed plate, and a rotary joint is connected to the second end of the upper fixed plate. The rotary joint is provided with the rotary damper, the first end of which is connected to the lower limit seat, and the second end of which is connected to the upper limit seat.

[0006] Preferably, the paint storage tank is further equipped with a liquid level sensor, which can monitor the liquid level in the paint storage tank.

[0007] Furthermore, the paint storage unit is also equipped with a liquid level monitoring and control system. When the liquid level sensor detects that the liquid level in the paint storage tank is lower than the immersion height of the blade tenon, the liquid level sensor feeds back the liquid level information of the paint storage tank to the liquid level monitoring and control system. The liquid level monitoring and control system controls the touch-up pump to replenish paint to the paint storage tank through the paint tank. When the blade tenon is finished being painted, the liquid level monitoring and control system can control the touch-up pump to store the remaining paint in the paint storage tank into the paint tank.

[0008] Preferably, the rotation direction of the plush wheel is opposite to the movement direction of the horizontal slide.

[0009] Furthermore, when the felt wheel is not in contact with the blade tenon, the felt wheels on both sides of the paint storage tank are in a tensioned state. When the felt wheel contacts the blade tenon, the felt wheel can coat the end of the blade tenon. As the blade tenon continues to move forward, under the action of the adaptive moving component and the horizontal movement of the horizontal slide, the felt wheel opens to both sides, and the felt wheel can coat the side of the blade tenon. When the felt wheel disengages from the blade tenon, the felt wheel is automatically tensioned, and the felt wheel can coat the tail of the blade tenon, thereby completing the coating of each end face of the blade tenon.

[0010] In another aspect, the present invention provides a painting method for an adaptive painting device for blade tenons, comprising the following steps:

[0011] S1. Install multiple blades sequentially onto the blade clamp, and install the blade clamp onto the horizontal slide.

[0012] S2. Control the horizontal slide to move horizontally above the paint storage tank, and control the horizontal slide to move vertically downward to immerse the blade tenon into the paint storage tank;

[0013] S3. Control the painting motor to start rotating the plush wheel;

[0014] S4. Control the horizontal slide to move the blade tenon forward. When the plush wheel contacts the blade tenon, the plush wheel begins to brush the end of the blade tenon.

[0015] S5. The blade tenon continues to move forward. Under the action of the adaptive moving component and the horizontal movement of the horizontal slide, the plush wheel opens to both sides and begins to brush the side of the blade tenon.

[0016] S6. When the blade tenon is out of contact with the plush wheel, the plush wheel performs a brushing operation on the tail of the blade tenon.

[0017] S7. After the coating is completed, control the horizontal slide to move vertically upward to lift the blade tenon from the paint storage tank, and control the horizontal slide to move horizontally to send the blade tenon to the drying station.

[0018] S8. Dry the blade tenon. After drying, remove the dried blade from the blade fixture and complete the brushing of the blade.

[0019] The features and beneficial effects of this invention are:

[0020] 1. The adaptive painting device and painting method for blade tenons provided by the present invention, by setting an adaptive moving component and an tilting adjustment component, can adaptively adjust the direction of the velvet wheel according to the shape of the blade tenon, ensuring close contact between the velvet wheel and the blade tenon, and has good adaptability to the blade tenon, reducing the occurrence of missed coating and missed spots during the painting process.

[0031] An adaptive painting device for blade tenons according to the present invention, such as Figure 1 As shown, it includes a paint storage unit 1 and an adaptive paint coating unit 2.

[0032] like Figure 2 As shown, the paint storage unit 1 includes a paint storage tank 11, a base 12, a paint can 13, and a touch-up pump 14. The paint storage tank 11 is mounted on the base 12. The paint can 13 and the touch-up pump 14 are located in the base 12. The paint can 13 is connected to the paint inlet of the touch-up pump 14 through a pipe 15. The paint outlet of the touch-up pump 14 is connected to the paint storage tank 11 through a pipe 15. The paint storage tank 11 and its accessories are treated with anti-corrosion coating.

[0033] like Figure 3 and Figure 4As shown, the adaptive painting unit 2 is symmetrically arranged on both sides of the paint storage tank 1. The adaptive painting unit 2 includes an adaptive moving component, a tilt adjustment component, a painting motor 21, and a plush wheel 22. The adaptive moving component 21 is fixed to the paint storage tank 11 by a base plate. The adaptive moving component includes a base plate 23, a guide post 24, a spring 25, a support plate 26, and a moving plate 27. The first ends of both sides of the base plate 23 are symmetrically provided with guide supports 28. The first end of the guide post 24 is slidably provided on the guide support 28. The second end of the guide post 24 is connected to the first end of the support plate 26. The spring 25 is provided on the guide post 24. The upper end surface of the base plate 23 is provided with a sliding guide rail. The lower end surface of the moving plate 27 is provided with a slider. The moving plate 27 is located on the bottom plate 23. The paint storage unit 1 is mounted on a sliding plate 23, with the slider slidably mounted on the sliding guide rail. The tilt adjustment component is mounted on the moving plate 27, and the paint spraying motor 21 is mounted on the upper fixed plate 35 of the tilt adjustment component. The output shaft of the paint spraying motor 21 is connected to the first end of the plush wheel shaft 29 via a coupling, and the second end of the plush wheel shaft 29 is provided with a plush wheel 22. A horizontal slide table 3 is provided above the paint storage unit 1. The adaptive moving component and the tilt adjustment component can adaptively adjust the direction of the plush wheel 22 according to the shape of the blade tenon 6, ensuring close contact between the plush wheel 22 and the blade tenon 6. It has good adaptability to the blade tenon 6 and can ensure that there is no missed coating or missed spots. The plush wheel 22 achieves adaptive painting of the blade tenon 6 under the drive of the paint spraying motor 21. Multiple blades 4 are sequentially installed on the blade clamp 5, and the blade clamp 5 is mounted on the horizontal slide table 3. The horizontal slide table 3 moves vertically downward and immerses the blade tenon into the paint storage tank 11. The adaptive painting unit 2 is started to paint the blade tenon.

[0034] like Figure 4 As shown, the tilt adjustment assembly includes a lower fixed plate 32, a rotary damper 33, and an upper fixed plate 35. The lower fixed plate 32 is connected to the movable plate 27, and the first end of the lower fixed plate 32 is provided with a lower limit seat 31. The first end of the upper fixed plate 35 is provided with an upper limit seat 34, and the second end of the lower fixed plate 32 is connected to the second end of the upper fixed plate 35 via a rotating joint. A rotary damper 33 is provided at the rotating joint. The first end of the rotary damper 33 is connected to the lower limit seat 31, and the second end of the rotary damper 33 is connected to the upper limit seat 34.

[0035] In a preferred embodiment, the paint storage tank 11 is further equipped with a liquid level sensor 16, which monitors the liquid level in the paint storage tank 11. The paint storage unit 1 is also equipped with a liquid level monitoring and control system. When the liquid level sensor 16 detects that the liquid level in the paint storage tank 11 is lower than the immersion height of the blade tenon 6, the liquid level sensor 16 feeds back the liquid level information of the paint storage tank 11 to the liquid level monitoring and control system. The liquid level monitoring and control system controls the touch-up pump 14 to replenish paint to the paint storage tank 11 through the paint tank 13. When the blade tenon 6 is finished being painted, the liquid level monitoring and control system can control the touch-up pump 14 to store the remaining paint in the paint storage tank 11 into the paint tank 13.

[0036] Specifically, different models of blades correspond to different liquid levels in the paint storage tank 11 to ensure uniform paint application and accurate paint application position on the blade tenon 6.

[0037] Specifically, the rotation direction of the felt wheel 22 is opposite to the movement direction of the horizontal slide 3. When the felt wheel 22 is not in contact with the blade tenon 6, the felt wheels 22 on both sides of the paint storage tank 11 are in a tensioned state. When the felt wheel 22 contacts the blade tenon 6, the felt wheel 22 can paint the end of the blade tenon. As the blade tenon 6 continues to move forward, under the action of the adaptive moving component and the horizontal movement of the horizontal slide, the felt wheel 22 opens to both sides, and the felt wheel 22 can paint the side of the blade tenon 6. When the felt wheel 22 is out of contact with the blade tenon 6, the felt wheel 22 is automatically tensioned, and the felt wheel 22 can paint the tail of the blade tenon 6, thereby completing the painting of each end face of the blade tenon 6.

[0038] A second aspect of the present invention provides a painting method for an adaptive painting apparatus for blade tenons, comprising the following steps:

[0039] S1. Install multiple blades 4 sequentially onto the blade clamp 5, and install the blade clamp 5 onto the horizontal slide table 3.

[0040] S2. Control the horizontal slide 3 to move horizontally above the paint storage tank 11, and control the horizontal slide 3 to move vertically downward to immerse the blade tenon into the paint storage tank 11.

[0041] S3. Control the painting motor 21 to drive the plush wheel 22 to start rotating;

[0042] S4. Control the horizontal slide 3 to move the blade tenon 6 forward. When the plush wheel 22 contacts the blade tenon 6, the plush wheel 22 begins to brush the end of the blade tenon 6.

[0043] S5. The blade tenon 6 continues to move forward. Under the action of the adaptive moving component and the horizontal movement of the horizontal slide 3, the plush wheel 22 opens to both sides and begins to brush the side of the blade tenon 6.

[0044] S6. When the blade tenon 6 is out of contact with the tufting wheel 22, the tufting wheel 22 performs a brushing operation on the tail of the blade tenon 6.

[0045] S7. After the coating is completed, control the horizontal slide 3 to move vertically upward to lift the blade tenon from the paint storage tank 11, and control the horizontal slide 3 to move horizontally to send the blade tenon to the drying station.

[0046] S8. Dry the blade tenon. After drying, remove the dried blade from the blade fixture and complete the brushing of the blade.

[0047] The specific operation steps of this invention are as follows:

[0048] like Figures 1-5 As shown, the adaptive painting device and spraying method for blade tenons of the present invention have the following specific operation steps:

[0049] S1. Install multiple blades 4 sequentially onto the blade clamp 5, and install the blade clamp 5 onto the horizontal slide table 3.

[0050] S2. Control the horizontal slide 3 to move horizontally above the paint storage tank 11, and control the horizontal slide 3 to move vertically downward to immerse the blade tenon into the paint storage tank 11, so that most of the blade protection area is submerged.

[0051] S3. Control the painting motor 21 to drive the plush wheel 22 to start rotating;

[0052] S4. Control the horizontal slide 3 to drive the blade tenon 6 forward. When the plush wheel 22 contacts the blade tenon 6, the plush wheel 22 begins to approach various parts of the blade tenon 6, squeezing out the air bubbles around the blade tenon 6, achieving full paint coverage of the blade protection area. The plush wheel 22 begins to brush the end of the blade tenon 6.

[0053] S5. The blade tenon 6 continues to move forward. Under the action of the adaptive moving component and the horizontal movement of the horizontal slide 3, the plush wheel 22 opens to both sides and begins to brush the side of the blade tenon 6.

[0054] S6. When the blade tenon 6 is out of contact with the tufting wheel 22, the tufting wheel 22 performs a brushing operation on the tail of the blade tenon 6.

[0055] S7. After the coating is completed, control the horizontal slide 3 to move vertically upward to lift the blade tenon from the paint storage tank 11, and control the horizontal slide 3 to move horizontally to send the blade tenon to the drying station.

[0056] S8. Dry the blade tenon. After drying, remove the dried blade from the blade fixture and complete the brushing of the blade.

[0057] This invention, by incorporating an adaptive movement component and a tilt adjustment component, can adaptively adjust the direction of the felt wheel according to the shape of the blade tenon, ensuring close contact between the felt wheel and the blade tenon. This provides excellent adaptability to the blade tenon, preventing missed coating or areas of uneven application. Simultaneously, driven by a painting motor, the felt wheel achieves adaptive painting of the blade tenon, ensuring automation of the painting process, guaranteeing the quality of the anti-corrosion paint coating on parts, improving on-site production efficiency, and shortening the cycle time. Furthermore, the paint storage tank is equipped with a liquid level sensor and a liquid level monitoring and control system, which can automatically monitor the paint level and perform real-time fine-tuning and touch-up during production to maintain the paint level within the set range. This achieves the automatic touch-up function of the paint level detection machine, ensuring stable painting quality of the equipment.
