[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3 , a powder metallurgy part cleaning and oil immersion device, including a pool body 1. A thin partition 2 is arranged in the middle of the pool body 1, and the thin partition 2 divides the pool body 1 into a cleaning area 3 and an oil immersion area 4. Cylinders 5 are connected to the inner bottom walls of both the cleaning area 3 and the oil immersion area 4. The telescopic ends of the cylinders 5 are fixedly connected with a conveying device 6 for transporting powder metallurgy parts, and two adjacent conveying devices 6 can be connected to each other so that the powder metallurgy parts above the cleaning area 3 can be transported above the oil immersion area 4 through the conveying device 6.

[0018] The conveying device 6 includes a frame 61 fixedly connected to the telescopic end of the cylinder 5. A conveyor belt 62 is installed in the frame 61. The conveyor belt 62 is driven by a driving module, and water filtering holes 63 are arranged on the conveyor belt 62. The water filtering holes 63 are used to drain the excess liquid on the powder metallurgy workpieces soaked in the cleaning liquid or lubricating liquid into the pool.

[0019] Specifically, the driving module includes a roller body for driving the movement of the conveyor belt 62. One end of the outer side of one roller is fixedly connected with a turntable 64. Above the thin partition 2, there are two driving wheels 7 for driving the rotation of the turntable 64. The two driving wheels 7 are fixed on the pool body 1 and driven by a motor. The driving wheels 7 drive the rotation of the turntable 64, thereby driving the operation of the conveyor belt 62 to realize the conveyance of powder metallurgy parts, and transferring them from above the cleaning area 3 to above the oil immersion area 4.

[0020] Furthermore, the two frame bodies 61 are respectively in contact with the inner walls of the cleaning area 3 and the oil immersion area 4. The gap between the frame body 61 and the conveyor belt 62 is less than 5 mm to prevent the powder metallurgy parts from falling from the conveyor belt 62 into the pool body 1.

[0021] Among them, the cleaning area 3 is filled with a cleaning liquid, and an ultrasonic cleaning structure for ultrasonic cleaning is arranged in the cleaning area 3. The oil immersion area 4 is filled with lubricating oil. Since the cleaning effect of the cleaning liquid is better than that of the lubricating oil, it is necessary to perform strong cleaning on the powder metallurgy parts before oil immersion. Using ultrasonic waves in cooperation with the cleaning liquid can achieve a good cleaning effect.

[0022] Working principle: For a powder metallurgy part cleaning and oil immersion device of the present utility model, during use, first place the powder metallurgy parts in the cleaning area 3 for cleaning. After the cleaning is completed, the air cylinder pushes the frame body 61 to rise until the turntable 64 is in contact with the driving wheel 7. After waiting for the powder metallurgy parts on the conveyor belt 62 to dry, the driving wheel 7 drives the rotation of the turntable 64, thereby driving the operation of the conveyor belt 62. The conveyor belt 62 conveys the powder metallurgy parts located above the cleaning area 3 to above the oil immersion area 4. Then the air cylinder 5 descends, and the powder metallurgy parts enter for internal oil immersion. After the oil immersion is completed, the conveyor belt 62 is lifted, and the powder metallurgy parts are sent away from above the oil immersion area 4.

[0023] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
