Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts processing, in particular to an engine connecting rod oil immersion device. Background Art

[0002] As a key component of the crank-connecting rod mechanism of internal combustion engines (such as automobiles, ships, and aircraft engines, etc.), the engine connecting rod undertakes the important task of converting the reciprocating linear motion of the piston into the rotational motion of the crankshaft. In the production and processing of the engine connecting rod, it is necessary to use an engine connecting rod oiling device to immerse the engine connecting rod in oil so that the surface of the engine connecting rod is covered with a uniform layer of anti-rust oil.

[0003] The existing engine connecting rod oil immersion device pours an appropriate amount of anti-rust oil into the oil immersion tank of the oil immersion device, then fixes the material box containing the appropriate amount of engine connecting rods on a steel cable through a hook, and drives the material box down by a winch so that the material box containing the appropriate amount of engine connecting rods is immersed in the anti-rust oil to achieve oil immersion of the engine connecting rods. However, during the oil immersion process, since a large number of engine connecting rods need to be immersed in oil at one time, it takes a certain amount of time for the surface of the engine connecting rod to be evenly covered with a layer of anti-rust oil when the material box is immersed in the anti-rust oil, and the oil immersion efficiency is not good.
