Description

Technical Field

[0001] This utility model belongs to the technical field of metal liner surface treatment equipment, specifically relating to a nano-coating treatment equipment for a pure titanium liner surface. Background Technology

[0002] The surface treatment of pure titanium inner liner mainly adopts nano-titanium plating technology, which forms a nano-scale titanium metal film on the surface through physical vapor deposition, significantly improving wear resistance and corrosion resistance; it is mainly used in high-precision components such as medical devices and precision instruments, such as implants and molds.

[0003] Problems with existing technology: The existing nano-coating equipment for pure titanium inner liner surfaces has the following shortcomings during use: First, the loading and unloading of the inner liner mostly rely on manual handling and positioning, which is cumbersome and inefficient, and difficult to adapt to batch processing needs; Second, the inner liner fixing mechanism has poor stability and is prone to displacement during the spraying process, resulting in uneven coating thickness and affecting coating quality. Utility Model Content

[0004] The purpose of this invention is to provide a nano-coating treatment device for the surface of a pure titanium inner liner, which can effectively avoid the displacement and shaking of the inner liner during the spraying process, ensure the uniform thickness of the nano-coating on the surface of the liner, and fundamentally solve the coating quality problem caused by the poor stability of traditional fixing mechanisms.

[0005] The specific technical solution adopted by this utility model is as follows: A nano-coating treatment device for the surface of a pure titanium inner liner includes a treatment box, a movable plate slidably disposed at the bottom of the treatment box, and a fixing mechanism for clamping the inner liner disposed on the top of the movable plate. A partition is fixed inside the processing box and above the fixing mechanism, and a spraying mechanism for spraying the inner liner surface is provided on the partition.

[0006] Both sides of the bottom of the processing box are equipped with electric slide rails, and the bottom of the moving plate is equipped with an electric slider that cooperates with the electric slide rails, which is used to drive the fixing mechanism on the moving plate to move into or out of the processing box.

[0007] The fixing mechanism includes a support cylinder located at the center of the top of the movable plate. A suction cup is provided on the top of the support cylinder, and an air hole communicating with the support cylinder is opened at the center of the top of the suction cup.

[0008] The support cylinder has a sealed sliding piston disc inside, and a piston rod is provided at the bottom of the piston disc. The bottom end of the piston rod extends to the bottom of the moving plate and is fixed with a limit slider.

[0009] The bottom of the processing box, located on both sides of the piston rod, is provided with a limiting slide bar that slides in contact with the limiting slider.

[0010] The limiting slide bar includes a vertical part, a horizontal part perpendicular to the vertical part, and an inclined part integrally formed with the horizontal part. The inner bottom of the processing box is fixed with a support plate fixed to the inclined part.

[0011] The bottom of the piston disc is provided with a plurality of telescopic guide rods connected to the moving plate along the circumferential direction. A first spring is sleeved on the telescopic guide rod, and the two ends of the first spring are respectively connected to the piston disc and the moving plate.

[0012] The outer surface of the support cylinder is provided with multiple telescopic elastic rods at equal intervals along the circumference, and a clamping plate is fixed between the upper and lower telescopic elastic rods.

[0013] The spraying mechanism includes a paint tank mounted on a partition, and a conveying shaft is rotatably mounted through the top center of the partition. The paint tank is rotatably and sealed to the top of the conveying shaft via a feeding pipe on a feeding pump.

[0014] An L-shaped nozzle is provided at the bottom end of the conveying shaft tube, and a motor is provided at the top of the partition. The output shaft of the motor is connected to the conveying shaft tube through a bevel gear set.

[0015] The technical effects achieved by this utility model are as follows: This invention utilizes a combination of an electric slide rail and an electric slider to drive a moving plate, which in turn moves the fixing mechanism into or out of the processing box, eliminating the need for manual handling of the inner liner for positioning or unloading. Compared to the cumbersome process of traditional equipment relying on manual operation, this not only reduces labor costs and operational intensity but also avoids the time-consuming problem of manual positioning. It is suitable for the continuous processing needs of batches of inner liners, significantly improving the overall working efficiency of the equipment.

[0016] The fixing mechanism of this utility model adopts a dual fixing method of "negative pressure adsorption + elastic auxiliary support": on the one hand, through the linkage between the limiting slide rod and the piston plate, a negative pressure is automatically formed inside the support cylinder when the moving plate moves into the processing box, and the suction cup tightly adsorbs the inner wall of the inner liner to achieve the main fixing; on the other hand, the telescopic elastic rod and the arc-shaped clamp on the outside of the support cylinder can tightly abut against the inner wall of the inner liner through the elastic force of the second spring to form a reverse auxiliary support; the dual fixing structure effectively avoids the displacement and shaking of the inner liner during the spraying process, ensuring that the thickness of the nano coating on the surface of the liner is uniform, and fundamentally solving the coating quality problem caused by the poor stability of traditional fixing mechanisms.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figures 1-4 As shown, a nano-coating treatment device for the surface of a pure titanium inner liner includes a treatment box 1, a movable plate 6 is slidably arranged at the bottom of the treatment box 1, and a fixing mechanism for clamping the inner liner is arranged on the top of the movable plate 6. Inside the processing box 1 and above the fixing mechanism, there is a partition 2, on which a spraying mechanism for spraying the inner liner surface is provided.

[0021] like Figure 2 As shown, electric slide rails 4 are provided on both sides of the bottom of the processing box 1, and electric sliders 5 that cooperate with the electric slide rails 4 are provided on the bottom of the moving plate 6, which are used to drive the fixing mechanism on the moving plate 6 to move into or out of the processing box 1.

[0022] According to the above structure, the electric slide rail 4 and the electric slider 5 work together to drive the fixed mechanism on the moving plate 6 to move into or out of the processing box 1, thereby facilitating the loading and unloading of the inner liner, improving the working efficiency of the equipment, and also improving the practicality of the equipment.

[0023] like Figures 2-4 As shown, the fixing mechanism includes a support cylinder 7 located at the top center of the movable plate 6, a suction cup 8 located at the top of the support cylinder 7, and an air hole 9 communicating with the support cylinder 7 located at the top center of the suction cup 8. The support cylinder 7 has a piston disc 10 that slides inside a sealed environment. A piston rod 13 is provided at the bottom of the piston disc 10. The bottom end of the piston rod 13 extends to the bottom of the moving plate 6 and is fixed with a limit slider 14. Limiting slide rods 15 are provided at the bottom of the processing box 1 and on both sides of the piston rod 13, which slide in contact with the limit sliders 14. The limiting slide bar 15 includes a vertical part, a horizontal part perpendicular to the vertical part, and an inclined part integrally formed with the horizontal part. A support plate 16 fixed to the inclined part is fixed to the bottom of the processing box 1. The bottom of the piston disc 10 is provided with a plurality of telescopic guide rods 11 connected to the movable plate 6 along the circumferential direction. A first spring 12 is sleeved on the telescopic guide rod 11, and the two ends of the first spring 12 are respectively connected to the piston disc 10 and the movable plate 6.

[0024] According to the above structure, the telescopic guide rod 11 includes a first mounting tube and a first insertion rod inserted into the first mounting tube. One end of the first insertion rod is slidably connected to the inside of the first mounting tube. In use, the inner liner is inverted and placed on the support cylinder 7, so that the inner wall of the inner liner rests on the suction cup 8. The moving plate 6 is moved into the processing box 1 by the electric slide rail 4 and the electric slider 5. During the movement, the limiting slider 14 slides in contact with the inclined part on the limiting slide rod 15, and the limiting slider 14 pulls the piston rod 13 down. The piston rod 13 drives the piston plate 10 down, changing the position of the piston plate 10 inside the support cylinder 7. Air pressure, through the air hole 9 and in conjunction with the suction cup 8, suctions the inner liner, stabilizing and fixing it. The vertical part on the limiting slide rod 15 is used to limit the movement of the limiting slider 14, allowing the inner liner to move accurately to the spraying work area. The cooperation of the telescopic guide rod 11 and the first spring 12 allows the limiting slide rod 15 to release the limiting slider 14 when the inner liner is moved out of the processing box 1. Then, the elastic force of the first spring 12 pushes the piston plate 10 upward, contacting the suction force of the suction cup 8 on the inner liner, thereby releasing the fixation of the inner liner, facilitating the disassembly of the inner liner, and increasing the practicality of the equipment.

[0025] like Figures 3-4 As shown, multiple telescopic elastic rods 17 are equidistantly arranged on the outer surface of the support cylinder 7 along the circumferential direction, and a clamping plate 18 is fixed between the upper and lower telescopic elastic rods 17.

[0026] According to the above structure, the telescopic elastic rod 17 includes a second mounting tube and a second plug rod inserted into the second mounting tube. One end of the second plug rod is slidably connected to the inside of the second mounting tube. The inside of the second mounting tube is provided with a second spring connected to the second plug rod. The multiple clamps 18 can provide reverse support to the inner wall of the inner liner, further improving the stability of fixing the inner liner.

[0027] like Figures 1-3As shown, the spraying mechanism includes a paint tank 3 disposed on a partition 2. A conveying shaft tube 19 is rotatably installed through the top center of the partition 2. The paint tank 3 is rotatably connected to the top of the conveying shaft tube 19 through a conveying pipe on a feeding pump. An L-shaped nozzle 21 is provided at the bottom of the conveying shaft tube 19, and a motor 20 is provided at the top of the partition plate 2. The output shaft of the motor 20 is connected to the conveying shaft tube 19 through a bevel gear set.

[0028] According to the above structure, during use, the paint is conveyed to the L-shaped nozzle 21 by the feed pump on the paint tank 3 along the feed pipe and the conveying shaft pipe 19, and sprayed onto the inner surface of the inner liner from the L-shaped nozzle 21. The motor 20, in conjunction with the bevel gear set, drives the conveying shaft pipe 19 to rotate, and the conveying shaft pipe 19 drives the L-shaped nozzle 21 to rotate, thereby spraying the inner liner completely.

[0029] The working principle of this utility model is as follows: the electric slide rail 4 is started, the electric slider 5 drives the moving plate 6 to move out of the processing box 1; the staff puts the pure titanium inner liner to be processed upside down on the support cylinder 7, so that the bottom of the inner wall of the inner liner is in contact with the suction cup 8; at this time, the second spring in the telescopic elastic rod 17 releases the elastic force, pushing the clamping plate 18 to abut against the inner side wall of the inner liner, realizing the initial support and positioning of the inner liner. Reactivate the electric slide rail 4, and the electric slider 5 will move the moving plate 6 and the inner liner into the treatment box 1. During the movement, the limiting slider 14 will gradually contact the inclined part of the limiting rod 15 and slide along the inclined part. The limiting slider 14 will drive the piston rod 13 to move downward. The piston rod 13 will push the piston disc 10 to move downward in the support cylinder 7. The space inside the support cylinder 7 will increase and the air pressure will decrease. Through the air hole 9, a negative pressure will be formed between the suction cup 8 and the inner wall of the inner liner. The suction cup 8 will firmly adhere to the inner liner, thus completing the stable fixation of the inner liner. When the moving plate 6 moves to the designated position inside the treatment box 1, the limiting slider 14 will slide to the vertical part of the limiting rod 15 to achieve precise positioning of the moving plate 6. The inner liner will be located exactly below the L-shaped nozzle 21 in the spraying work area. Start the feed pump and motor 20 that are equipped with the paint tank 3; the feed pump delivers the nano paint in the paint tank 3 to the feed shaft tube 19 through the feed pipe, and the paint flows along the feed shaft tube 19 to the L-shaped nozzle 21 and is sprayed onto the outer surface of the inner tank; at the same time, the output shaft of the motor 20 drives the feed shaft tube 19 to rotate around its own axis through the bevel gear set, and the feed shaft tube 19 drives the L-shaped nozzle 21 to rotate synchronously, so as to achieve comprehensive and uniform spraying of the outer surface of the inner tank; After the spraying is completed, the feed pump and motor 20 are turned off; the electric slide rail 4 is started, and the electric slider 5 drives the moving plate 6 and the sprayed inner liner to move out of the processing box 1; during the removal process, the limiting slider 14 gradually disengages from the vertical and horizontal parts of the limiting slide rod 15, the first spring 12 is no longer under the pressure of the piston plate 10, and the released elastic force pushes the piston plate 10 to move upward in the support cylinder 7, the air pressure in the support cylinder 7 returns to normal pressure, and the suction force of the suction cup 8 on the inner liner is released; the staff can directly remove the inner liner to complete the unloading; then, the moving plate 6 can be moved back into the processing box 1 to carry out the processing operation of the next inner liner.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
