Technical Field

[0001] The utility model relates to the technical field of engine bearing bush coating processing, in particular to a lubricating and wear-resistant coating processing device for an engine bearing bush. Background Art

[0002] The engine bearing is a key component inside the engine, mainly used to support and reduce the friction of the main journal and connecting rod journal. The bearing will be subjected to tremendous pressure and friction when it comes into direct contact with the high-speed rotating journal. Therefore, it is necessary to coat the bearing with a wear-resistant coating to reduce the friction coefficient between the bearing and the journal, reduce direct wear between metals, and protect the bearing itself from wear.

[0003] The coating on the bearing is wet right after it is applied. The wet coating is relatively soft, so it needs to be dried naturally to solidify before the bearing can be moved. However, the natural drying process usually takes longer, which will extend the entire production cycle. Utility Model Content

Passing through the second groove 14 and fixedly connected to the output end of the first motor 29, the first motor 29 is started, and the first motor 29 drives the threaded rod 22 to rotate, thereby driving the second support frame 24 to move along the threaded rod 22. At this time, the first support frame 23 slides along the slide rod 21, and the slide rod 21 plays a limiting role. The movement of the first support frame 23 and the second support frame 24 drives the first top plate 25 to move, thereby driving the hot air blower 26 to move, and move the hot air blower 26 to be directly above the bearing shell to facilitate drying of the bearing shell coating. The hot air blower 26 cooperates with the design of the ventilation pipe 27 and the wind collecting hood 28 to facilitate the concentration of hot air flow, so that it can directly act on the coating surface, accelerate the drying process, reduce the curing time compared to natural drying, and improve production efficiency.

[0028] The spraying assembly 3 includes a third support frame 31 slidably connected to the outer surface of the sliding rod 21, a fourth support frame 32 threadedly connected to the outer surface of the threaded rod 22, a second top plate 33 fixedly connected to the top of the third support frame 31 and the fourth support frame 32, a paint box 34 fixedly connected to the top of the second top plate 33, a drainage pipe 35 fixedly passed through the bottom end of the paint box 34, a shunt pipe 37 fixedly passed through the bottom end of the drainage pipe 35, a nozzle 38 fixedly passed through the outer surface of the shunt pipe 37, and a valve 36 fixedly connected to the outer surface of the drainage pipe 35. The drainage pipe 35 passes through the second top plate 33. The rotation of the threaded rod 22 drives the fourth support frame 32 to move. At this time, the third support frame 31 slides along the sliding rod 21 at the same time, thereby driving the second top plate 33 and the paint box 34 to move. The valve 36 is opened, and the paint inside the paint box 34 enters the shunt pipe 37 through the drainage pipe 35, and is finally sprayed out through the nozzle 38 to spray the bearing shell.

[0029] A second motor 341 is fixedly connected to one side of the paint box 34, a rotating rod 342 is fixedly connected to the output end of the second motor 341, a stirring blade 343 is fixedly connected to the outer surface of the rotating rod 342, the rotating rod 342 passes through the paint box 34, and the second motor 341 is started. The stirring blade 343 is driven by the rotating rod 342 and continuously rotates inside the paint box 34, so as to effectively prevent the paint from settling and stratifying and ensure that the paint is evenly mixed.

[0030] A first through hole 12 is provided on the upper surface of the workbench 1, a placement groove and a second through hole 41 are provided on the upper surface of the placement table 4, a collecting box 6 is movably provided at the bottom end of the workbench 1, the first through hole 12 and the second through hole 41 are provided correspondingly, the collecting box 6 is located directly below the first through hole 12, and the placement groove is used to place the bearing shell. During the coating process of the bearing shell, the corresponding setting of the first through hole 12 and the second through hole 41 forms a channel directly leading to the collecting box 6 below, so that the excess paint produced drips into the collecting box 6, thereby reducing the pollution of the workbench 1 surface and facilitating the unified cleaning and treatment at a later stage.

[0031] A fixing plate 5 is fixedly connected to the top of the placing table 4, a spring 51 is fixedly connected to the inner side of the fixing plate 5, and a clamping plate 511 is fixedly connected to one end of the spring 51. The use of the spring 51 provides elastic force for the clamping plate 511, which is convenient for automatically adjusting the clamping force to achieve adaptive clamping, thereby ensuring that the bearing shells are stably and safely fixed in the correct position to avoid displacement or slipping during processing.

[0032] A mounting plate 61 is fixedly connected to one side of the collection box 6, and a locking bolt 611 is threadedly connected between the mounting plate 61 and the workbench 1. The collection box 6 is fixed to the collection box 6 by the locking bolt 611. Removing the locking bolt 611 makes it easy to take out the collection box 6 and process the waste recovered inside the collection box 6.

[0033] When in use, place the bearing shell on the top of the placement groove, and then fix the bearing shell on the top of the placement table 4 through the spring 51 and the clamping plate 511, start the first motor 29, the first motor 29 drives the threaded rod 22 to rotate, and the rotation of the threaded rod 22 drives the fourth support frame 32 to move. At this time, the third support frame 31 slides along the slide rod 21, thereby driving the second top plate 33 and the paint box 34 to move, open the valve 36, and the paint inside the paint box 34 enters the diversion pipe 37 through the drain pipe 35, and finally is sprayed out through the nozzle 38 to spray the bearing shell. During the coating process of the bearing shell, the corresponding setting of the first through hole 12 and the second through hole 41 forms a channel directly leading to the collection box 6 below, so that the excess paint generated The paint drips into the collection box 6, reducing the pollution of the workbench 1 surface. The rotation of the threaded rod 22 drives the first support frame 23 and the second support frame 24 to move, thereby driving the first top plate 25 and the hot air blower 26 to move. There is a distance between the first top plate 25 and the second top plate 33. When the hot air blower 26 moves to just above the bearing, the paint box 34 is away from the bearing. The hot air blower 26 cooperates with the design of the ventilation pipe 27 and the wind collecting hood 28 to concentrate the hot air flow so that it directly acts on the coating surface, accelerating the drying process, reducing the curing time compared to natural drying, and improving production efficiency. After the processing is completed, remove the locking bolt 611 to facilitate taking out the collection box 6 and processing the waste recovered inside the collection box 6.
