Description
Technical Field
The invention relates to the technical field of automobile part manufacturing, in particular to automatic equipment for oiling a crankshaft.
Background
Original bent axle fat liquoring adopts the manual mode, and in a confined space promptly, the operator takes gauze mask etc. to protect, adopts the air pump to atomize the special rust-resistant oil of bent axle in the watering can earlier, then handheld watering can sprays the bent axle on the whole work or material rest. And the other method is that the crankshaft is hung into a container containing rust-proof oil by using a lifting hook by an operator, and all the crankshaft is soaked in the rust-proof oil for rust-proof treatment. The oiling mode has a plurality of defects:
1. The crankshaft adopts the atomizing watering can to spray oil, the crankshaft is placed on the material rack, the watering can is adopted to spray oil to the crankshafts one by one, the crankshafts are very heavy, the overturning is impossible, the workload is large, oil spraying dead angles can occur frequently, the material racks are stacked layer by layer, the middle part of the crankshafts are shielded by the outer crankshafts, and dead angles can be caused.
2. The sanitary environment is poor. The operator is in airtight space, and the atomized rust preventive oil fills the whole space, and the operator is provided with protective articles, but still can have a great threat to physical and mental health. Especially in summer, operators are very stuffy in the closed space. Although the operators do enough protection work, after working, the operators are fully stained with rust preventive oil up and down, which brings a lot of inconvenience to the operators.
3. The crankshaft oiling process comprises the steps of cleaning a crankshaft, placing the crankshaft into a material rack, enabling a forklift fork to enter an oiling room, oiling by an operator, enabling the forklift fork to go out of the oiling room, packaging and warehousing, and is complex in working procedure, so that the production line production is hindered.
4. According to practical experience, the finished crankshaft must be guaranteed to be sent into an oiling room for oiling within four hours, otherwise, the surface of the crankshaft is at risk of rusting. However, sometimes the oil coating operator goes off duty, and the production line is still continued, so that the crankshaft cannot be coated with oil in time. The production connection is very troublesome, and the phenomenon of missing or delayed oiling occurs slightly.
5. The flash point of the rust preventive oil is more than 60 ℃, operators operate in a closed space with high oil mist density, and the fork lift truck goes in and out to and fro, so that the risk of fire is high.
6. There is also a need for a large enclosure that can accommodate both the forklift and the work stack, yet be equipped with an forklift.
7. The high requirement on the working quality of operators can cause incomplete oiling once the tiger. Sometimes it cannot be found that the corrosion of the crankshaft is finally caused, and even the crankshaft is scrapped due to serious corrosion. Once addressed to the user, would have unpredictable adverse consequences.
8. Uneven oiling can be generated, oiling is not performed on certain parts of the crankshaft, the surface color is grey and dull due to uneven appearance of the crankshaft, and the positions with and without oiling have little contrast and are difficult to check on site.
9. Because the crankshaft needs to be volatilized and dried for a certain time after being oiled, the crankshaft can possibly take a long time in the dark or winter, and in the process, the crankshaft can possibly absorb dust in the air to cause pollution, so that the cleanliness is influenced. Contamination is even more serious if packaging is urgent.
10. If the oil is coated in the container, the efficiency is too low; if the defects of dust, vapor and the like exist in the crankshaft, cross contamination can be caused; meanwhile, a lot of rust-proof oil can be stored in the oil hole, and the rust-proof oil can not flow out completely due to the angle problem when the crankshaft is lifted out, so that great waste is caused.
11. When the crankshaft is oiled, a lot of rust-proof oil is gathered on the material frame and the partition plate, and pollution is generated to the material frame. If too much oil is collected on the material rack, the forklift can pollute the whole production environment in the transportation process.
