Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically to a surface treatment device for 3D metal printed parts. Background Technology

[0002] With the rapid development of metal additive manufacturing (3D printing) technology, its application in aerospace, medical devices, industrial molds and other fields is becoming increasingly widespread. 3D metal printing technology can manufacture complex geometries and lightweight structural parts that are difficult to achieve with traditional processing methods, such as metal tubes with conformal cooling channels, lattice cores or integrated functions.

[0003] However, 3D printed metal parts typically have high surface roughness, with defects such as unfused particles, oxide layers, and support residues, which severely affect their fatigue performance, corrosion resistance, and assembly accuracy. Therefore, surface treatment technologies (such as spraying) must be used to improve their surface quality, impart specific functions (such as wear resistance, corrosion resistance, and heat insulation), and meet the requirements of final use. Surface spraying has become one of the key steps in the post-processing of 3D metal printing.

[0004] Currently, the spraying of tubular or rod-shaped 3D printed metal parts often borrows from traditional pipe spraying methods, such as the device with conveyor rollers disclosed in Chinese Patent No. CN219463801U. This type of device supports and conveys the workpiece using rollers, but it has some problems: the freshly sprayed portion comes into contact with the surface of the conveyor roller, causing the coating to adhere to the roller's surface, resulting in uneven coating on the metal part and affecting the spraying effect.

[0005] To address this, a surface treatment device for 3D metal printed parts is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a surface treatment device for 3D metal printed parts in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution: A surface treatment device for 3D metal printed parts includes a base, a tilt control component on the top of the base, a fixing plate on the top of the tilt control component, an internal expansion positioning mechanism for limiting the movement of metal pipes on the right side of the fixing plate, a rotation adjustment mechanism for controlling the rotation of the internal expansion positioning mechanism on the left side of the fixing plate, a mounting frame fixedly connected to the center of the top surface of the base, and an automatic spraying mechanism on the surface of the mounting frame.

[0008] Furthermore, the tilt control assembly includes a mounting base, which is fixedly connected to the top surface of the base. A support column is rotatably connected to the inner wall of the mounting base, and the top of the support column is fixedly connected to a fixing plate. An electric push rod is rotatably connected to the inner wall of the mounting base, and a hinge seat is rotatably connected to the telescopic end of the electric push rod, and the hinge seat is fixedly connected to the support column.

[0009] Furthermore, the rotation adjustment mechanism includes a first motor, which is fixedly mounted on the right side of the fixed plate. The output end of the first motor is fixedly connected to a first rotating shaft. A drive sprocket is fixedly sleeved on the surface of the first rotating shaft. A chain is meshed on the surface of the drive sprocket. A second rotating shaft is rotatably connected to the surface of the fixed plate. A driven sprocket is fixedly connected to the left end of the second rotating shaft, and the driven sprocket meshes with the chain.

[0010] Furthermore, the internal expansion positioning mechanism includes a support frame, and the support frame is fixedly connected to the right end of the second rotating shaft. A second motor is fixedly mounted on the surface of the support frame, and a double-ended screw is fixedly connected to the output end of the second motor. A support rod is threadedly connected to the surface of the double-ended screw. A sliding column is fixedly connected to the surface of the support frame, and the support rod is slidably connected to the sliding column. A support bar is fixedly connected to the right end of the support rod.

[0011] Furthermore, the automatic spraying mechanism includes an automatic spray gun, which is fixedly mounted on the top of the mounting frame. The output end of the automatic spray gun is fixedly connected to a conveying pipe, and a nozzle is provided at the bottom of the conveying pipe.

[0012] Furthermore, the number of tilt control components is two sets, and the two sets of tilt control components are symmetrically arranged on the bottom front side and bottom rear side of the fixed plate, and the number of internal expansion positioning mechanisms is multiple sets.

[0013] The beneficial effects of this utility model are as follows: The metal pipe fitting is fitted onto the surface of the internal expansion positioning mechanism, which tensions and limits its position. Then, an automatic spraying mechanism sprays the surface of the metal pipe fitting. Simultaneously, a rotation adjustment mechanism controls the internal expansion positioning mechanism to rotate, causing the metal pipe fitting to rotate and be fully sprayed. After spraying, a tilt control component tilts the fixing plate to the right, releasing the internal expansion positioning mechanism's limiting effect. Under gravity, the metal pipe fitting slides to the right, thus achieving unloading. This system facilitates rapid spraying of metal pipe fitting surfaces, resulting in more uniform spraying compared to existing technologies. The coating on the metal pipe fitting surface does not come into contact with other parts of the device, ensuring optimal spraying results. Attached Figure Description

[0018] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0019] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use.

Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1 , Figure 3 As shown, a surface treatment device for 3D metal printed parts includes a base 1, a tilt control component 2 on the top of the base 1, a fixing plate 3 on the top of the tilt control component 2, an inner expansion positioning mechanism 5 for limiting the metal tube on the right side of the fixing plate 3, and a rotation adjustment mechanism 4 for controlling the rotation of the inner expansion positioning mechanism 5 on the left side of the fixing plate 3. A mounting frame 6 is fixedly connected to the center of the top surface of the base 1, and an automatic spraying mechanism 7 is provided on the surface of the mounting frame 6. More specifically, the metal tube is placed on the surface of the inner expansion positioning mechanism 5, and the inner expansion positioning mechanism 5 is used to tension and limit the metal tube. Then, the automatic spraying mechanism 7 is used to spray the surface of the metal tube. At the same time, the rotation adjustment mechanism 4 controls the inner expansion positioning mechanism 5 to rotate, thereby driving the metal tube to rotate and fully spraying the metal tube. After the spraying is completed, the tilt control component 2 is used to tilt the fixing plate 3 to the right. At this time, the limiting effect of the inner expansion positioning mechanism 5 is released, and the metal tube will slide to the right under the action of gravity, thereby realizing the unloading.

[0021] like Figure 1 , Figure 4 As shown, the tilt control component 2 includes a mounting base 201, which is fixedly connected to the top surface of the base 1. A support column 202 is rotatably connected to the inner wall of the mounting base 201, and the top of the support column 202 is fixedly connected to the fixing plate 3. An electric push rod 203 is rotatably connected to the inner wall of the mounting base 201. A hinge seat 204 is rotatably connected to the telescopic end of the electric push rod 203, and the hinge seat 204 is fixedly connected to the support column 202. It should be noted that by operating the electric push rod 203, its telescopic end is shortened, thereby pulling the support column 202 to rotate, which in turn drives the fixing plate 3, the rotation adjustment mechanism 4, and the internal expansion positioning mechanism 5 to rotate, thereby causing the metal pipe to tilt to the right.

[0022] like Figure 2 , Figure 3As shown, the rotation adjustment mechanism 4 includes a first motor 401, which is fixedly mounted on the right side of the fixed plate 3. The output end of the first motor 401 is fixedly connected to a first rotating shaft 402. A drive sprocket 406 is fixedly sleeved on the surface of the first rotating shaft 402. A chain 403 is meshed on the surface of the drive sprocket 406. A second rotating shaft 405 is rotatably connected to the surface of the fixed plate 3. A driven sprocket 404 is fixedly connected to the left end of the second rotating shaft 405. The driven sprocket 404 meshes with the chain 403. More specifically, by operating the first motor 401, the first rotating shaft 402 is driven to rotate, which in turn drives the drive sprocket 406 to rotate. Then, through the transmission action of the chain 403, multiple driven sprockets 404 are simultaneously driven to rotate, which in turn drives the second rotating shaft 405 to rotate. This controls the rotation of the internal expansion positioning mechanism 5 and the metal pipe.

[0023] like Figure 1 , Figure 2 As shown, the internal expansion positioning mechanism 5 includes a support frame 501, which is fixedly connected to the right end of the second rotating shaft 405. A second motor 502 is fixedly mounted on the surface of the support frame 501. A double-ended screw 503 is fixedly connected to the output end of the second motor 502. A support rod 504 is threadedly connected to the surface of the double-ended screw 503. A sliding column 505 is fixedly connected to the surface of the support frame 501, and the support rod 504 is slidably connected to the sliding column 505. A support bar 506 is fixedly connected to the right end of the support rod 504. It should be noted that the operation of the second motor 502 drives the double-ended screw 503 to rotate. Under the action of the thread, the support rod 504 slides along the surface of the sliding column 505, thereby driving the support bar 506 to move toward the inner wall of the metal pipe. The two support bars 506 tension and limit the inner wall of the metal pipe.

[0024] like Figure 1 As shown, the automatic spraying mechanism 7 includes an automatic spray gun 701, which is fixedly installed on the top of the mounting frame 6. The output end of the automatic spray gun 701 is fixedly connected to a conveying pipe 702, and a nozzle 703 is provided at the bottom of the conveying pipe 702. More specifically, the paint is output through the automatic spray gun 701, and the paint flows through the inside of the conveying pipe 702 and is sprayed onto the surface of the metal pipe from the nozzle 703.

[0025] like Figure 1 As shown, there are two sets of tilt control components 2, and the two sets of tilt control components 2 are symmetrically arranged on the front and rear sides of the bottom of the fixed plate 3. There are multiple sets of internal expansion positioning mechanisms 5. It should be noted that by symmetrically arranging two sets of tilt control components 2, the fixed plate 3 is balanced and stable. By setting multiple sets of internal expansion positioning mechanisms 5, multiple sets of metal pipes can be limited at the same time, thereby allowing multiple metal pipes to be sprayed simultaneously.

[0026] In summary: The metal pipe fitting is fitted onto the surface of the internal expansion positioning mechanism 5, which tensions and limits its position. The automatic spraying mechanism 7 then sprays the surface of the metal pipe fitting. Simultaneously, the rotation adjustment mechanism 4 controls the internal expansion positioning mechanism 5 to rotate, causing the metal pipe fitting to rotate and thus achieving full spraying. After spraying, the tilt control component 2 tilts the fixing plate 3 to the right, releasing the limiting effect of the internal expansion positioning mechanism 5. Under gravity, the metal pipe fitting slides to the right, achieving unloading. This method facilitates rapid spraying of the metal pipe fitting surface, resulting in more uniform spraying compared to existing technologies. The coating on the metal pipe fitting surface does not come into contact with other parts of the device, ensuring a superior spraying effect.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
