Description

Technical Field

[0001] This utility model relates to the technical field of spraying devices, and more particularly to a spraying device for a chassis shell. Background Technology

[0002] As a protective outer layer for assembled components and electrical elements, the chassis not only protects these components from external corrosion and damage and provides stable support, but also plays a crucial role in enhancing the overall aesthetic value of the equipment and user satisfaction. After the chassis is shaped, it needs to undergo a painting process. This step not only beautifies the appearance of the chassis, but also enhances its corrosion resistance, wear resistance, and aging resistance.

[0003] Given that the chassis shell has multiple painting surfaces, the current main method of operation is manual spraying. The chassis shell is placed on a rotating platform, and workers use spray guns to spray each surface one by one. After each surface is completed, the platform is rotated to the next surface to continue the work.

[0004] However, workers' hands are easily contaminated when adjusting the turntable, and holding the spray gun again may contaminate it. At the same time, the entire spraying device is directly exposed to the air, which not only pollutes the workshop environment but may also pose a potential threat to the physical and mental health of workers. Utility Model Content

[0024] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0025] The coating device for the chassis shell of this utility model is described below with reference to the accompanying drawings.

[0026] like Figures 1 to 6 As shown, the spraying device for the chassis shell of this utility model embodiment may include a housing 1, a turntable 2, an adjustment component 3, a limiting component 4, a stepping component 5, a transmission component 6, and a spray gun 7.

[0027] The box 1 has a partition 12 inside, which divides the box 1 into a first cavity 10 and a second cavity 11. The first cavity 10 is connected to a first sealing door 8 by a hinge. The first sealing door 8 has two operating holes 80. The second cavity 11 is provided with a second sealing door 9, which has a through groove 90.

[0028] It should be noted that the first sealing door 8 described in this embodiment can seal the first cavity 10 to prevent the gas inside the first cavity 10 from leaking out. In order to better purify the air inside the first cavity 10, a purifier (not shown in the figure) can be installed on the box 1. In addition, for ease of operation, the first sealing door 8 is made of transparent material.

[0029] Furthermore, the operating hole 80 is connected to the opening of a rubber glove (not shown in the figure). The rubber glove is placed inside the housing 1. When the housing needs to be sprayed, the worker can simply put his hand into the rubber glove through the operating hole 80, thereby preventing the gas in the first cavity 10 from escaping through the operating hole 80.

[0030] In the embodiments of this application, the second sealing door 9 can be fixed to the housing 1 by bolts.

[0031] The adjustment component 3 is installed on the lower inner wall of the housing 1 and passes through the partition 12. The turntable 2 is installed on the top of the adjustment component 3 and the upper surface of the turntable 2 is provided with a first groove 20. The limiting component 4 is installed in the first groove 20.

[0032] It should be noted that the adjustment component 3 can adjust the height of the turntable 2, thereby making it convenient to adjust the height of the turntable 2 according to the height of the spraying personnel, making the spraying operation more comfortable.

[0033] Furthermore, the limiting component 4 can limit the chassis from inside the housing to prevent the housing from shifting when the turntable 2 is rotated.

[0034] The pedal assembly 5 is located inside the second cavity 11 and is provided through the through groove 90. The transmission assembly 6 is installed inside the second cavity 11 and is connected to the adjustment assembly 3 and the pedal assembly 5 respectively. The spray gun 7 is located inside the first cavity 10.

[0035] In the embodiments of this application, the foot pedal component 5 and the transmission component 6 work together to drive the adjustment component 3 and the turntable 2 to rotate, eliminating the need for direct hand contact and thus preventing contamination of the hands and the spray gun 7.

[0036] Furthermore, the first cavity 10 is equipped with a bracket, on which the spray gun 7 can be suspended for easy access.

[0037] In one embodiment of this utility model, such as Figure 1 As shown, the adjustment assembly 3 may include a rod sleeve 30 and a telescopic rod 31. One end of the rod sleeve 30 is rotatably connected to the lower inner wall of the housing 1, and the other end of the rod sleeve 30 extends through the partition 12 into the interior of the first cavity 10. One end of the telescopic rod 31 is placed inside the rod sleeve 30, and the other end of the telescopic rod 31 is connected to the turntable 2.

[0038] In the embodiments of this utility model, the telescopic rod 31 is slidably connected to the rod sleeve 30, and the telescopic rod 31 and the rod sleeve 30 can be fixed by bolts or screws.

[0039] In one embodiment of this utility model, such as Figure 3As shown, the limiting assembly 4 may include a driving member 40, two connecting rods 41, two guide rails 42, two sliding plates 43, and two limiting plates 44. The driving member 40 is installed in the first groove 20, the two guide rails 42 are arranged opposite to each other in the first groove 20, the two sliding plates 43 are slidably connected to the corresponding limiting plates 44, the two ends of the connecting rods 41 are hinged to the output end of the driving member 40 and the corresponding sliding plate 43, and the two limiting plates 44 are connected to the corresponding sliding plates 43.

[0040] It should be noted that the driving component 40 described in this embodiment can be an electric push rod or a pneumatic rod. One end of the limiting plate 44 is higher than the table surface of the turntable 2. Through the cooperation of the driving component 40, the connecting rod 41 and the guide rail 42, the distance between the two limiting plates 44 can be adjusted, thereby facilitating the limiting of chassis shells of different sizes.

[0041] Furthermore, such as Figure 4 As shown, the transmission assembly 6 may include a first transmission shaft 60, a first gear 61, a second gear 62, a second transmission shaft 63, and two bevel gears 64. The first transmission shaft 60 is rotatably mounted on the lower inner wall of the housing 1. The first gear 61 is mounted on the first transmission shaft 60. A support sleeve 13 is fixedly connected to the rod sleeve 30. The second gear 62 is rotatably mounted on the support sleeve 13 and meshes with the first gear 61. The second transmission shaft 63 is rotatably mounted inside the second cavity 11 via a support plate 14. The two bevel gears 64 are respectively mounted on the first transmission shaft 60 and the second transmission shaft 63 and mesh with each other.

[0042] In the embodiments of this application, when the second drive shaft 63 is driven to rotate, the first drive shaft 60, the first gear 61 and the second gear 62 are driven to rotate through the cooperation between the two bevel gears 64. At the same time, the rotation direction of the second gear 62 can control the rod sleeve 30 to rotate or remain stationary.

[0043] Furthermore, such as Figure 5 and Figure 6 As shown, the inner wall of the second gear 62 is provided with a ratchet 16, and the support sleeve 13 is provided with a second groove 130. A pawl 15 is rotatably connected in the second groove 130, and the pawl 15 is connected to the inner wall of the second groove 130 through a first spring 17.

[0044] In the embodiments of this application, the inner wall of the ratchet 16 is provided with teeth, and one end of the pawl 15 is positioned between two adjacent teeth. See [link to relevant documentation]. Figure 6 When the second gear 62 drives the ratchet 16 to rotate clockwise, the pawl 15 cannot play a limiting role, and the lever sleeve 30 cannot rotate at this time. When the second gear 62 drives the ratchet 16 to rotate counterclockwise, one end of the pawl 15 is stuck between two adjacent teeth, thereby enabling the lever sleeve 30 to rotate.

[0045] Specifically, such as Figure 1 and Figure 4 As shown, the pedal assembly 5 may include a connecting plate 50, a pedal 51, and a second spring 52. One end of the connecting plate 50 is connected to the second drive shaft 63, and the other end of the connecting plate 50 is connected to the pedal 51 through the through groove 90. The two ends of the second spring 52 are connected to the connecting plate 50 and the inner lower wall of the housing 1, respectively.

[0046] In the embodiments of this application, when it is necessary to rotate the turntable 2, the relevant personnel press down on the pedal 51, which, through the cooperation of the connecting plate 50, drives the second transmission shaft 63 to rotate clockwise. With the cooperation of the two bevel gears 64 and the first gear 61, the second gear 62 is driven to rotate counterclockwise. At the same time, with the cooperation of the pawl 15 and the ratchet 16, the adjustment component 3 and the turntable 2 are driven to rotate, thereby realizing the rotation of the chassis housing.

[0047] Specifically, when the chassis is being painted, the relevant personnel open the first sealing door 8, place the chassis on the turntable 2, and then start the drive unit 40. The telescopic rod of the drive unit 40 extends and, through the cooperation of the connecting rod 41 and the guide rail 42, drives the two sliding plates 43 to move away from each other, so that the two limiting plates 44 abut against the inner wall of the chassis.

[0048] Then the first sealing door 8 can be closed. The relevant personnel put their hands into rubber gloves through the operating hole 80 and use the spray gun 7 to spray the front of the chassis. After spraying, the relevant personnel press down on the foot pedal 51. With the cooperation of the connecting plate 50, the second drive shaft 63 is driven to rotate clockwise. With the cooperation of the two bevel gears 64 and the first gear 61, the second gear 62 is driven to rotate counterclockwise. Due to the cooperation of the pawl 15 and the ratchet 16, the adjusting component 3 and the turntable 2 are driven to rotate counterclockwise by a certain angle, so that the other side of the chassis rotates to the position facing the first sealing door 8. In this way, the other side can be sprayed. The operation is convenient and will not cause pollution to the hands and the spray gun 7. It can also seal harmful gases inside the first cavity 10, thereby reducing the threat to the health of workers.

[0049] In summary, the spraying device for the chassis shell of this utility model uses a foot pedal control method to drive the turntable to rotate, which not only effectively prevents the hands and spray gun from being contaminated, but also seals the chassis shell inside the first cavity during the spraying process, effectively preventing the leakage of harmful gases and greatly reducing the potential threat to workers' health.
