Abstract
Description
Technical Field
[0001] This application relates to the field of painting technology, and more particularly to a painting apparatus for engine cylinder head processing. Background Technology
[0002] Painting is a crucial step in the manufacturing process of engine cylinder heads. It not only protects the cylinder head surface from rust and corrosion but also enhances its appearance. However, traditional engine cylinder head painting equipment has several drawbacks.
[0003] Early painting equipment mostly used fixed nozzles, which could only paint specific surfaces of the engine cylinder head, making it difficult to achieve full coverage. This resulted in many corners and edges of the engine cylinder head not being adequately painted. During subsequent use, these unprotected areas were prone to corrosion and damage, seriously affecting the service life and performance of the engine cylinder head. Therefore, this patent requires an upgrade and modification based on existing technology. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a painting apparatus for engine cylinder head processing, overcoming the deficiencies of the prior art. It aims to solve the problem that painting specific surfaces of the engine cylinder head is difficult to achieve comprehensive coverage. This results in many corners and edges of the engine cylinder head not being adequately painted.
[0005] To achieve the above objectives, this application provides the following technical solution: a painting device for engine cylinder head processing, comprising an operating table, characterized in that a support rod is fixedly connected to the top of the operating table, a top rod is fixedly connected to one end of the top of the support rod, a top spray head is fixedly connected to the bottom of the top rod, a fixed inclined rod is fixedly connected to one end of the top rod, a side spray head is fixedly connected to the lower end of the fixed inclined rod, a movable table is fixedly connected to the outer side of the operating table, a lead screw is rotatably connected inside the movable table, a sliding block is threadedly connected to the outer side of the lead screw, a rotating shaft is rotatably connected to the top of the sliding block, and a loading plate is fixedly connected to the top of the rotating shaft.
[0006] By adopting the above technical solution, the engine cylinder head is placed on top of the carrier plate during use. Then, the side nozzles and top nozzles are turned on to spray the engine cylinder head. By rotating the carrier plate, the side nozzles and top nozzles can spray the engine cylinder head from all directions. By rotating the lead screw, the outer sliding block moves back and forth with the lead screw. Due to the rectangular structure of the engine cylinder head, the spray thickness will be different at the positions of the engine cylinder head that are farther from the spring and those that are closer to the spring during the spraying process. At this time, when the carrier plate is rotated to the position of the engine cylinder head that is farther from the spring, the rotation of the lead screw will move the carrier plate closer to the side nozzle, thereby ensuring that each surface of the engine cylinder head is sprayed evenly.
[0007] As a preferred technical solution of this application, the operating table has a cavity inside, and a partition plate is fixedly connected to the middle of the operating table. The partition plate divides the internal cavity of the operating table into an upper cavity and a lower cavity. The upper cavity of the operating table has a relaxation shaft at both ends. The upper cavity of the operating table has a partition opening through the middle. A second motor is fixedly connected to the outer side of the operating table. The drive end of the second motor is fitted with a transmission belt, which is fitted on the outer side of the relaxation shaft and the rotation shaft.
[0008] By adopting the above technical solution, the second motor is started, which drives the transmission belt sleeved on the outside of the second motor drive end to rotate along the rotation direction of the second motor. During the movement, the transmission belt will drive the tension shaft and the rotation shaft to rotate. In this way, the rotation of the rotation shaft will drive the top loading plate to rotate, and then drive the engine cylinder head on the top of the loading plate to rotate, thereby achieving all-round painting of the engine cylinder head.
[0009] As a preferred technical solution of this application, a first slide rod is fixedly connected inside the lower cavity of the operating table, and a moving block is slidably connected to both sides of the first slide rod. The moving block is slidably connected inside the lower cavity of the operating table, and the first slide rod is fixedly connected to the inner side of the moving block at the outer side of the first slide rod. A sliding groove is provided in the middle of the partition plate, and one end of the bottom of the relaxation shaft passes through the sliding groove and is fixedly connected to the moving block.
[0010] By adopting the above technical solution, the moving block can be stably slid inside the operating table through the setting of the first slide rod, and then the top tension shaft can be driven to slide along the sliding groove track. Under the rotation of the lead screw, the sliding block will move back and forth inside the moving table. At this time, the bottom loading plate will move back and forth. When the loading plate moves away from the operating table, the transmission belt will drive the tension shaft to move to the middle of the operating table. When the transmission belt moves towards the operating table, the tension shaft will move to both ends of the operating table under the action of the spring, so as to ensure that the transmission belt is always taut and thus ensure the stability of the transmission.
[0011] As a preferred technical solution of this application, the cavity on the operating table is rotatably connected to a limiting shaft at the partition position, and the transmission belt slides against the outside of the limiting shaft.
[0012] By adopting the above technical solution, the transmission belt can be limited by the setting of the limiting shaft, preventing the transmission belt from rubbing against the separation position during the movement process.
[0013] As a preferred technical solution of this application, a second slide rod is fixedly connected inside the moving stage at both sides of the lead screw, the sliding block is slidably connected to the outside of the second slide rod, and a first motor is fixedly connected to the outside of the moving stage. The drive end of the first motor passes through the moving stage and is fixedly connected to the lead screw.
[0014] By adopting the above technical solution, the setting of the second slide bar ensures the stability of the sliding block during the movement process. By starting the first motor, the lead screw is driven to rotate, which in turn drives the sliding block connected by the outer thread to move back and forth along the direction of the lead screw, thereby realizing the movement of the loading tray along the moving platform.
[0015] As a preferred technical solution of this application, a baffle is fixedly connected inside the moving platform at the top position of the second slide rod and the lead rod, and the baffle slides through the sliding block.
[0016] By adopting the above technical solution, the baffle can effectively protect the lead screw. When the side nozzles and top nozzles are used to paint the engine cylinder head on the top of the cargo tray, the paint can be effectively prevented from contaminating the lead screw.
[0017] As a preferred technical solution of this application, a control button is fixedly provided on the outer side of the support rod, and the control button is electrically connected to the first motor and the second motor.
[0018] By adopting the above technical solution, the position of the engine cylinder head can be adjusted by controlling the button, thereby achieving all-round painting of the engine cylinder head.
[0019] As a preferred technical solution of this application, an observation window is fixedly connected to the top of the operating table on both sides of the support rod, and the observation window is made of transparent tempered glass.
[0020] By adopting the above technical solution, staff can observe the painting process of the engine cylinder head in real time through the observation window and make real-time adjustments to the position as needed.
[0021] The beneficial effects of this application are:
[0022] 1. In this utility model, the painting device drives the engine cylinder head to rotate in all directions by rotating the carrier plate. The side spray nozzles and the top spray nozzles work together to ensure that all angles are covered. At the same time, in response to the problem of different side spraying distances caused by the rectangular structure of the engine cylinder head, the lead screw drives the carrier plate to move back and forth for precise adjustment, which effectively avoids the phenomenon of uneven spraying thickness caused by changes in distance and greatly improves the painting quality.
[0023] 2. In this utility model, the first slide bar and the moving block of the lower cavity cooperate with each other. When the loading plate moves, the transmission belt is kept taut by the action of the spring, which ensures the stability of the transmission. In addition, the second slide bars on both sides of the lead screw in the moving table effectively ensure the smooth movement of the sliding block, providing strong support for the stable operation of the equipment.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] Reference Figure 1-4A painting device for engine cylinder head processing includes an operating table 1. The operating table 1 is characterized by a support rod 3 fixedly connected to its top, a top rod 5 fixedly connected to one end of the top of the support rod 3, a top spray nozzle 7 fixedly connected to the bottom of the top rod 5, a fixed inclined rod 6 fixedly connected to one end of the top rod 5, a side spray nozzle 12 fixedly connected to the lower end of the fixed inclined rod 6, a movable table 2 fixedly connected to the outer side of the operating table 1, a lead screw 23 rotatably connected inside the movable table 2, a sliding block 9 threadedly connected to the outer side of the lead screw 23, a rotating shaft 10 rotatably connected to the top of the sliding block 9, and a loading tray 11 fixedly connected to the top of the rotating shaft 10. In use, the engine cylinder head is placed on top of the loading tray 11, and then the side spray nozzle 12 and the top spray nozzle 7 are turned on. The top nozzle 7 sprays the engine cylinder head. By rotating the carrier plate 11, the side nozzles 12 and the top nozzle 7 can spray the engine cylinder head from all directions. By rotating the lead screw 23, the outer sliding block 9 moves back and forth with the lead screw 23. Due to the rectangular structure of the engine cylinder head, the spray thickness will be different at the position of the side of the engine cylinder head farther from the spring 21 and the position of the side of the engine cylinder head closer to the spring 21 during the spraying process. At this time, when the carrier plate 11 is rotated to the position of the side of the engine cylinder head farther from the spring 21, the lead screw 23 rotates and moves the carrier plate 11 closer to the side nozzle 12, so as to ensure that each surface of the engine cylinder head can be sprayed evenly.
[0031] In this embodiment, as Figure 1 - Figure 4 As shown, the operating table 1 has an internal cavity. A partition plate 13 is fixedly connected to the middle of the operating table 1, dividing the internal cavity of the operating table 1 into an upper cavity and a lower cavity. The upper cavity of the operating table 1 has a tension shaft 18 at both ends, and a partition opening 16 is provided through the middle of the upper cavity of the operating table 1. A second motor 25 is fixedly connected to the outside of the operating table 1. A transmission belt 17 is sleeved on the drive end of the second motor 25. The transmission belt 17 is sleeved on the outside of the tension shaft 18 and the rotating shaft 10. By starting the second motor 25, the transmission belt 17 on the outside of the drive end of the second motor 25 is driven to rotate along the rotation direction of the second motor 25. During the movement, the transmission belt 17 drives the tension shaft 18 and the rotating shaft 10 to rotate. In turn, the rotation of the rotating shaft 10 drives the top loading tray 11 to rotate, and then drives the engine cylinder head on the top of the loading tray 11 to rotate, thereby realizing the all-round painting of the engine cylinder head.
[0032] In this embodiment, as Figure 1 - Figure 4As shown, a first slide rod 19 is fixedly connected inside the lower cavity of the operating table 1. Moving blocks 20 are slidably connected to both sides of the first slide rod 19. The moving blocks 20 are slidably connected inside the lower cavity of the operating table 1. The inner side of the moving blocks 20 is fixedly connected to the first slide rod 19 at a position outside the first slide rod 19. A sliding groove 14 is provided in the middle of the partition plate 13. One end of the bottom of the relaxation shaft 18 passes through the sliding groove 14 and is fixedly connected to the moving block 20. The first slide rod 19 enables the moving block 20 to slide stably inside the operating table 1, thereby driving the top relaxation shaft 1... 8 slides along the track of sliding groove 14. Driven by the rotation of lead screw 23, sliding block 9 will move back and forth inside moving platform 2. At this time, it will drive the bottom loading plate 11 to move back and forth. When the loading plate 11 moves away from the operating platform 1, the transmission belt 17 will drive the tension shaft 18 to move towards the middle of the operating platform 1. When the transmission belt 17 moves towards the operating platform 1, the tension shaft 18 will move towards both ends of the operating platform 1 under the action of spring 21, so as to ensure that the transmission belt 17 is always in a taut state, thereby ensuring the stability of transmission.
[0033] In this embodiment, as Figure 1 - Figure 4 As shown, the upper cavity of the operating table 1 is rotatably connected to the limiting shaft 15 at the position of the partition 16. The transmission belt 17 slides against the outside of the limiting shaft 15. The limiting shaft 15 can limit the transmission belt 17 to prevent the transmission belt 17 from scratching the partition 16 during the movement.
[0034] In this embodiment, as Figure 1 - Figure 4 As shown, a second slide bar 22 is fixedly connected to both sides of the lead screw 23 inside the moving platform 2. A sliding block 9 is slidably connected to the outside of the second slide bar 22. A first motor 24 is fixedly connected to the outside of the moving platform 2. The drive end of the first motor 24 passes through the moving platform 2 and is fixedly connected to the lead screw 23. The setting of the second slide bar 22 ensures the stability of the sliding block 9 during the movement. By starting the first motor 24, the lead screw 23 is driven to rotate, thereby driving the sliding block 9 with the outer thread connection to move back and forth along the direction of the lead screw 23, so as to realize the movement of the loading tray 11 along the moving platform 2.
[0035] In this embodiment, as Figure 1 -Place Figure 4 As shown, a baffle 8 is fixedly connected inside the moving platform 2 at the top position of the second slide bar 22 and the lead screw 23. The baffle 8 slides through the sliding block 9. The baffle 8 can effectively protect the lead screw 23. When the side spray nozzle 12 and the top spray nozzle 7 spray paint the engine cylinder head on the top of the cargo tray 11, it can effectively prevent the paint from contaminating the lead screw 23.
[0036] In this embodiment, as Figure 1 - Figure 4 As shown, a control button is fixedly installed on the outer side of the support rod 3. The control button is electrically connected to the first motor 24 and the second motor 25. The control button can be used to adjust the position of the engine cylinder head for painting, thereby achieving all-round painting of the engine cylinder head.
[0037] In this embodiment, as Figure 1 - Figure 4 As shown, observation windows 4 are fixedly connected to the top of the control panel 1 on both sides of the support rod 3. The observation windows 4 are made of transparent tempered glass. Through the observation windows 4, the staff can observe the painting of the engine cylinder head in real time and make real-time adjustments to the position as needed.
[0038] Working principle: The engine cylinder head is placed on the carrier tray 11, the side spray nozzle 12 and the top spray nozzle 7 are turned on, and the second motor 25 is started. The transmission belt 17 at its drive end drives the tension shaft 18 and the rotating shaft 10 to rotate, thereby causing the carrier tray 11 to rotate the engine cylinder head, achieving all-round painting. The first motor 24 is started to drive the lead screw 23 to rotate, causing the sliding block 9 to move back and forth along the direction of the lead screw 23, which in turn drives the carrier tray 11 and the engine cylinder head to move back and forth. Since the engine cylinder head is rectangular, when the carrier tray 11 moves the side of the engine cylinder head to a position far away from the spring 21, the rotation of the lead screw 23 drives the carrier tray 11 to move closer to the side spray nozzle 12 to ensure uniform spraying. When the carrier tray 11 moves, the transmission belt 17 drives the tension shaft 18 to move. The spring 21 ensures that the transmission belt 17 is always taut, ensuring stable transmission. At the same time, the limiting shaft 15 limits the transmission belt 17 to prevent it from scratching the separator 16.
[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
