Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts pretreatment, in particular to a mechanical parts production pretreatment device. Background Art

[0002] Pretreatment of mechanical parts production refers to the process of optimizing and improving workpieces, equipment and processing by a series of technical means in order to improve product quality, precision and processing efficiency during the production of mechanical parts. This process includes multiple steps, among which pickling is one of the important links, which plays a key role in removing surface contaminants and providing a clean and activated surface.

[0003] In the existing pretreatment process of mechanical parts production, although pickling treatment has a significant effect on removing oil, burrs and oxides on the surface of mechanical parts, the subsequent manual operation has many inconveniences and efficiency problems. In particular, after the pickling operation, the mechanical parts need to be taken out and dried one by one manually. This step not only increases the labor cost, but also reduces the automation and efficiency of the entire production line. Manual removal of mechanical parts is not only time-consuming and labor-intensive, but also easily affected by human factors, such as the operator's proficiency and work attitude, which may affect the removal process and further affect the subsequent production process. At the same time, manual operation also has certain safety risks, such as the splash of pickling liquid may cause harm to the operator. Therefore, we propose a pretreatment device for mechanical parts production. Utility Model Content

[0021] Working principle: First, the operator puts the mechanical parts to be processed into the placement screen frame 17, and locks the frame door with a lock to ensure safety during the processing, and then fills the pickling tank 2 with pickling liquid. At the beginning of pretreatment, the first motor 5 starts, and drives the rotating column 4 to rotate through the first drive shaft at its top. Since the rotating column 4 is connected to the placement screen frame 17, the placement screen frame 17 can rotate to the top of the pickling tank 2. Then, the second motor 10 starts working, and the second drive shaft at its top drives the threaded column 11 to rotate. Since the nut sleeve 12 is connected to the threaded column 11 through a threaded connection, the nut sleeve 12 will move up and down along the threaded column 11. At the same time, the nut sleeve 12 is connected to the cross plate 16 through the connecting block 15, so the cross plate 16 and the placement screen frame 17 will be immersed in the pickling tank 2 or lifted to the outside of the pickling tank 2 as the nut sleeve 12 rises and falls. During the pickling process, the mechanical parts are evenly treated in the pickling liquid to remove surface oil, burrs and oxides. During the pickling process, the second motor 10 drives the placement frame 17 to rotate inside the pickling tank 2, so that the pickling liquid is evenly in contact with the mechanical parts. After the pickling is completed, the second motor 10 is controlled to move the placement frame 17 upward, move it out of the pickling tank 2, and then let it stand to drain. Then, the first motor 5 is controlled to rotate the rotating column 4 again to move the placement frame 17 above the flushing tank 3, and then the second motor 10 is controlled to move the placement frame 17 down to the inside of the flushing tank 3. The external water source enters the flushing tank 3 through the water inlet pipe 8, and the mechanical parts are flushed through the nozzle 7 to remove the residual pickling liquid. The waste water after flushing is discharged through the drain pipe 9. After flushing is completed, the second motor 10 is controlled to move the screen frame 17 to a suitable height, and the fan 21 and the heating tube 22 in the chassis 19 start working, sucking air through the air inlet, and after being heated by the heating tube 22, it is blown to the rotating mechanical parts through the blowing port to achieve drying treatment. Finally, the dried mechanical parts can be easily taken out by unlocking the frame door, completing the entire pretreatment process.

After pickling and flushing, the third The motor 20 drives the fan 21 and the heating tube 22 to work, and the hot air generated is used to dry the mechanical parts. The whole process does not require human intervention, which not only avoids the risk of manual contact with the pickling solution, but also improves work efficiency and product quality. The device has a reasonable structural design and a high degree of automation, and has significant production advantages. At the same time, the third motor 20 is controlled to drive the placement frame 17 to rotate during the pickling immersion process, so that the mechanical parts can be evenly pickled in the pickling solution, which can ensure that the pickling solution is in full contact with the surface of the mechanical parts, thereby improving the pickling effect and ensuring that the oil, burrs and oxides on the surface of the mechanical parts are completely removed.
