Problems solved by technology

The processing technology of the traditional automobile engine oil pan is special machine processing, and the processing method is relatively single. It can only be processed one by one. Not only is the dimensional stability poor, but the rhythm between each process is not balanced, which is easy to cause waste of production capacity.

Abstract

The invention discloses an oil pan and a processing method thereof. The oil pan processing method comprises a first processing procedure, a second processing procedure and a third processing procedure; the first processing procedure comprises the following steps: clamping a to-be-processed oil pan body onto a first processing center, and utilizing a positioning hole in the oil pan body and the endface of the oil pan body for positioning; milling a cylinder block connecting surface; and drilling and reaming a first reference hole and a second reference hole; the second processing procedure comprises the following steps: clamping the oil pan body after being processed through the first processing procedure onto a second processing center, and utilizing the cylinder block connecting surface,the first reference hole and the second reference hole for positioning; and milling a belt mounting surface; and the third processing procedure comprises the following steps: clamping the oil pan body after being processed through the second processing procedure onto a third processing center, and utilizing the cylinder block connecting surface, the first reference hole and the second reference hole for positioning; milling a lower oil pan mounting surface; and tapping the internal thread of the positioning hole. The oil pan processing method can ensure product size stability and the pace balance among all procedures.

Description

technical field [0001] The invention belongs to the technical field of automobile parts manufacturing, and in particular relates to an oil pan and a processing method thereof. Background technique [0002] The oil pan is the lower half of the crankcase, also known as the lower crankcase. Its function is to close the crankcase as the shell of the oil storage tank, prevent impurities from entering, and collect and store the lubricating oil that flows back from the friction surfaces of the engine. Remove part of the heat to prevent oxidation of the lubricating oil. The processing technology of traditional automobile engine oil pan is special machine processing, and the processing method is relatively single. It can only be processed one by one. Not only is the dimensional stability poor, but the rhythm between each process is not balanced, which is easy to cause waste of production capacity. Contents of the invention [0003] In order to overcome the above-mentioned shortcom...
