Description

Technical Field

[0001] This utility model relates to the field of metal pipe manufacturing technology, specifically to a metal pipe spraying device. Background Technology

[0002] During the manufacturing, assembly, and maintenance of metal pipe fittings, specific areas often need to be ground, such as to remove welding marks, correct dimensional deviations, improve surface roughness, or prepare for surface pretreatment before coating. After grinding, the ground area needs to be sprayed.

[0003] Currently, when spraying the outer surface of metal pipe fittings, manual hand-held spray guns are usually used. However, this method is prone to uneven paint spraying on the outer surface of the metal pipe fittings, resulting in poor spraying effect. At the same time, manual spraying is slow, especially time-consuming for spraying batches of pipes, and the quality is greatly affected by the operator's skill, making it difficult to guarantee consistency. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a metal pipe spraying device, comprising an operating table and a turntable, a transfer device, and a spraying assembly mounted on the operating table, as well as a rotating assembly located below the turntable and opposite to the spraying assembly and the transfer device. The operating table is also equipped with a correction assembly located below the transfer device, and multiple workstations are mounted on the turntable.

[0005] The spraying assembly includes a vertical plate fixed to the operating table. A downward-pushing cylinder is installed on the top of the vertical plate and a push plate connected to the downward-pushing cylinder slides on the side. A sleeve that can cover the product inside is fixed on the push plate, and a spray pipe is installed on the sleeve.

[0006] Furthermore, the workstation includes multiple bearing seats fixed on the turntable, and a through pipe that can be opposite to the rotating component is fixed on the inner side of the bearing seat. The inner wall of the through pipe is provided with a protruding edge and three strips.

[0007] Furthermore, multiple supports are fixed on the operating platform, and a support plate that slides on the turntable surface is fixed between the multiple supports.

[0008] Furthermore, a sensing sensor is installed on the top of the support plate, and the opening of the through pipe has a groove on the same vertical line as the convex edge.

[0009] Furthermore, the rotating assembly includes a base plate fixed to the bottom of the operating table. An upward-pushing cylinder is installed at the bottom of the base plate, and a sliding plate connected to the upward-pushing cylinder is slidably installed on the side. Two support seats and a drive motor are installed on one side of the sliding plate. The drive shaft of the drive motor is rotatably connected to the support seats and passes through the base plate. A rotating block that is perpendicular and symmetrical to the through pipe is fixed at the top of the drive shaft.

[0010] Furthermore, the calibration assembly includes an upper plate fixed to the operating table, a rotating motor installed at the bottom of the inner plate of the upper plate, and a shaft seat fixed at the top. A suction block fixed to the drive end of the rotating motor is fixed inside the shaft seat, and an outer cylinder surrounding the suction block is fixed at the top. A second sensing sensor is installed on the outside of the outer cylinder.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The metal pipe spraying device uses a transfer device to sequentially place the product into the calibration component and the work station, which can adjust the product to the appropriate direction and place it into the work station for a precise positioning. The device then moves to the bottom of the spraying component via a rotating table. In conjunction with the rotating component, it can automatically complete the spraying of the polished area around the pipe. Therefore, it is suitable for mass production and can improve the spraying speed and consistency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 The metal pipe spraying device in this embodiment includes an operating table 1 and a turntable 12 installed at the center of the operating table 1. It also includes a transplanting device 11 and a spraying assembly 2 distributed around the turntable 12, as well as a rotating assembly 4 that is perpendicularly symmetrical to the spraying assembly 2 and the transplanting device 11 below the turntable 12. The operating table 1 is also equipped with a correction assembly 3 located below the transplanting device 11. Multiple workstations are rotatably installed on the turntable 12, and the rotating assembly 4 is located below the workstations.

[0022] In the above structure, the product is transferred to the calibration component by the transfer device and adjusted to the appropriate direction. Then, it is picked up and placed in the workstation. With the help of the turntable rotation, the product is placed under the spraying component. At this time, the rotating component moves up to position the workstation, and the spraying component moves to the appropriate position to spray. Then, the rotating component drives the workstation to rotate, and the product follows the rotation, thereby completing the spraying of paint on the polished end of the product, thus realizing automation.

[0023] like Figure 3 and 6 As shown in the diagram, the correction assembly 3 includes an upper plate 301 fixed on the operating table 1. The upper plate 301 is divided into a middle plate and a top plate. A rotary motor 302 is installed at the bottom of the middle plate of the upper plate 301, and a bearing 303 is fixed at the top of the top plate. A suction block 304, which is fixed to the drive end of the rotary motor 302, is fixed inside the bearing 303. The suction block 304 can be a magnet. An outer cylinder 305, which surrounds the suction block 304, is fixed at the top of the bearing 303. A second sensing sensor 306 is installed on the outer side of the outer cylinder 305 near the workstation. When the transfer device places the product onto the suction block, the suction block adsorbs and positions the pipe. Then, the rotary motor drives the suction block to rotate until the cut surface of the product coincides with the second sensing sensor, thereby adjusting the product to a suitable orientation. The pipe is then transferred to the workstation by the transfer device.

[0024] like Figure 2 and 6As shown in the diagram, the workstation includes multiple bearing seats 5 fixed on the turntable 12. A through-tube 6, which is opposite to the rotating assembly 4, is fixed to the inner side of each bearing seat 5. The rotational connection between the through-tube 6 and the bearing seat 5 encounters a certain resistance. The inner wall of the through-tube 6 has a raised edge 7 and three equally spaced strips 8, with the top of each strip 8 located in the middle of the raised edge 7. The strips provide support for the product, and the raised edge aligns with the cut surface of the product, thus limiting the product's position and preventing it from shifting during turntable rotation.

[0025] like Figure 1 and 2 Four supports 13 are fixed on the operating table 1, and a support plate 14 that slides on the surface of the turntable 12 is fixed between the four supports 13. A sensor 10 is installed on the top of the support plate 14 near the moving device 11. The opening of the tube 6 has a groove 9 that is on the same vertical line as the protruding edge 7. The supports and the support plate can support the turntable, and then the rotating component drives the tube to rotate until the groove coincides with the sensor 1, thereby ensuring that the direction of the tube movement is adapted to the direction of the product after correction, which can facilitate the transfer device to put the product into the tube.

[0026] like Figure 4 As shown in the diagram, the rotating assembly 4 includes a base plate 401 fixed to the bottom of the operating table 1. An upward-pushing cylinder 402 is mounted on the bottom of the base plate 401, and a sliding plate 403, fixed to the ejector end of the upward-pushing cylinder 402, is slidably mounted on the right side. Two support seats 405 and a drive motor 404 are mounted on the right side of the sliding plate 403. The drive shaft of the drive motor 404 is rotatably connected to the support seats 405 and passes through the top of the base plate 401. A rotating block 406, perpendicularly symmetrical to one of the through pipes 6, is fixed to the top of the drive shaft. By pushing the sliding plate upward with the upward-pushing cylinder, the rotating block can be brought into close contact with the bottom of the through pipe. In conjunction with the drive motor, the rotating block can rotate, thus rotating the through pipe and simultaneously rotating the product inside the through pipe.

[0027] like Figure 5 As shown in the diagram, the spraying assembly 2 includes a vertical plate 201 fixed on the operating table 1. A downward-pushing cylinder 202 is mounted on the top of the vertical plate 201, and a push plate 203, which slides on the left side and is fixed to the ejector end of the downward-pushing cylinder 202, is mounted on the push plate 203. A sleeve 204, which can cover the product inside, is fixed on the push plate 203. A spray pipe 205 is mounted on the sleeve 204 and is connected to an external spraying machine. The diameter of the sleeve 204 is equal to the diameter of the through pipe 6, and the inner diameter of the sleeve 204 is larger than the inner diameter of the through pipe 6. By rotating the assembly upwards to position the through pipe, and then the downward-pushing cylinder drives the sleeve to cover the product until the spray pipe is located at the polished area of ​​the product. By rotating the assembly, the outer side of the product can be sprayed evenly.

[0028] The working principle of the above embodiments is as follows:

[0029] The product is first gripped and placed into the outer cylinder by the transfer device, and positioned by the suction block. Then, the motor rotates, causing the product to rotate through the suction block. The device stops when the second sensor aligns with the cut surface of the product. During the product calibration process, the turntable rotates, aligning the workstation with the calibration component. At this time, the upward-pushing cylinder moves the rotating block to fit tightly against the bottom of the tube via the moving plate. Then, the drive motor rotates the rotating block, causing the tube to move with the bearing seat until the concave surface of the tube aligns with the first sensor. This allows the transfer device to clamp the calibrated product into the tube. The strip supports the product, and the convex edge extends into the cut surface of the product, thus providing a limiting function. The turntable then moves the product to the bottom of the spraying component. The rotating component first lifts and positions the tube, and then the downward-pushing cylinder moves the sleeve via the push plate to cover the product, aligning the spray nozzle with the polished end of the product to complete the spraying. During the spraying process, the rotating component drives the tube to rotate, thus completing the spraying of the outer perimeter of the tube. The above operation is then repeated to achieve cyclic spraying.

[0030] In summary, it can achieve automated spraying, is suitable for mass production, and can also effectively improve production efficiency and maintain consistent spraying thickness.
