Description

Technical Field

[0001] This utility model relates to the technical field of gear chamber processing, specifically to an automatic spray painting line for gear chambers and covers. Background Technology

[0002] The gear chamber is a core component of an engine or transmission, typically made of cast iron or aluminum alloy. To withstand the oil, high temperatures, vibration, and corrosive media encountered in its service environment, the gear chamber and its cover must be coated with a high-performance protective coating. This coating must not only be uniform and leak-free to ensure long-term corrosion resistance, but also possess good adhesion, oil resistance, and stone chip resistance, while not affecting subsequent sealing of mating surfaces and assembly precision. Currently, the coating of such workpieces is mostly done using traditional manual spray painting or general-purpose automated spray painting lines.

[0003] Existing automatic spray painting lines for gear chambers and covers are typically used to spray paint workpieces to improve their corrosion resistance. However, the spray painting process generates irritating or toxic gases, and the existing lines lack filtration and treatment to remove these gases, which can harm the health of workers and result in poor performance.

[0004] Therefore, we propose an automatic painting line for the gear chamber and cover to solve the problems mentioned above. Utility Model Content

A delivery pipe is fixedly installed through the top of the purification box 82 near the left front side, and the right end of the delivery pipe is connected to a suction pipe 83. Several suction pipes are fixedly installed at equal intervals on the right side of the suction pipe 83, and the right ends of all suction pipes extend through the inner cavity of the spray booth 2. Several activated carbon filter plates 84 are evenly fitted into the inner cavity of the purification box 82. A partition is attached to the front side of the bottom of each activated carbon filter plate 84, and the front side of each partition is fixedly installed on the inner wall of the inner cavity of the purification box 82, providing support for the activated carbon filter plates 84. An installation port is provided on the right side of the rear side of the 2. A sealing plate 85 is slidably inserted into the inner cavity of the installation port. Several T-shaped grooves are equally spaced on the front side of the sealing plate 85. A T-shaped slider is slidably installed in the middle of the inner cavity of each T-shaped groove. The front side of the T-shaped slider is fixedly installed on the adjacent activated carbon filter plate 84, which can be used to disassemble and replace the activated carbon filter plate 84. An L-shaped plate 86 is fixedly installed on the left side of the purification box 82 near the rear side. A threaded sleeve 87 is movably installed through the L-shaped plate 86 near the middle. A threaded rod 88 is threadedly installed in the inner cavity of the threaded sleeve 87, with one end extending to the outside. A movable plate 89 is fixedly installed on the right end of the threaded rod 88, which can be used to draw in the gas generated during painting, purify it, and then discharge it. At the same time, it can also disassemble and replace the activated carbon filter plate 84 to avoid poor purification effect after long-term use and to avoid harm to the health of the staff.

[0031] A pull handle 851 is fixedly installed at the middle of the rear side of the sealing plate 85, and several snap-fit ​​grooves 852 are equally spaced on the left side of the sealing plate 85 near the rear side.

[0032] A driven gear 871 is fixedly sleeved on the outer side of the threaded sleeve 87 near the right end, and a driving gear 872 meshes with the top of the driven gear 871. A transmission rod is fixedly installed through the middle of the driving gear 872. The right end of the transmission rod is movably installed on the purification box 82, and a hand crank 873 is fixedly installed on the left end of the transmission rod.

[0034] In this embodiment: When painting the workpiece, irritating and toxic gases are generated. At this time, the suction pump 81 can be activated. When the suction pump 81 is running, it draws the gases generated in the paint booth 2 through the suction pipe 83 and the air intake pipe, and delivers them to the inner cavity of the purification chamber 82. The gases are then purified and filtered by the activated carbon filter plate 84 before being discharged, preventing the irritating and toxic gases from harming the health of the workers. Furthermore, the activated carbon filter plate 84 can be disassembled and replaced afterwards. By rotating the handwheel 873, the handwheel 873 drives the drive gear 872 through the transmission rod. The drive gear 872, in turn, drives the driven gear 871. When the threaded sleeve 87 rotates, it drives the movable plate 89 to move to the left via the threaded rod 88. As the movable plate 89 moves to the left, it drives several square locking rods 891 to move to the left simultaneously, thus slowly moving away from the inner cavity of the adjacent locking groove 852. At this point, the sealing plate 85 can be locked. Then, pulling the pull handle 851 backward will stretch the sealing plate 85 to move backward. When the sealing plate 85 moves backward, it will also drive several activated carbon filter plates 84 to move backward to the outside of the purification box 82 via the T-shaped slider and T-shaped groove. Then, the activated carbon filter plates 84 can be disassembled, removed, and replaced to avoid affecting the filtration and purification effect after long-term use.
