Abstract

The invention relates to a machining method for a lower cylinder body single body of a three-cylinder engine. The machining method comprises the steps that a lower cylinder body to be machined is clamped on a clamp; a cylinder body connecting face is pre-milled; a second-order positioning hole is finely drilled; bolt running holes and oil duct holes in the periphery are finely drilled; a lower oilpan mounting face is milled, and threaded holes are drilled; a liquid level sensor mounting hole and a liquid level oil filter mounting hole are finely machined; a filter mounting face and threaded holes are finely machined; a third-order positioning hole is finely drilled; the cylinder body connecting face is finely milled; a fourth-order positioning hole is finely drilled; an oil seal mountinghole is finely milled; a balance shaft mounting face is finely milled, and threaded holes are drilled; a chain cover mounting face and a gearbox mounting face are pre-milled, and drilling threaded holes are drilled; oil duct hole sealing grooves and end faces are milled; oil duct holes and threaded holes are drilled in the end faces of the oil duct holes; and the chain cover mounting face, a starter mounting face and the gearbox mounting face are finely milled. The machining method is used for machining the lower cylinder body of the novel three-cylinder engine, the high-precision requirementand high stability of products are achieved through a more optimized process, and stable mass production and high machining precision of the products are guaranteed.

Description

technical field [0001] The invention relates to a processing method for a single lower cylinder body of a three-cylinder engine. Background technique [0002] With people's concerns about energy depletion and the reality of increasingly serious environmental pollution, countries around the world have strictly controlled vehicle energy consumption and exhaust emission standards. Based on the pressure of energy saving and emission reduction, the development direction of traditional energy vehicles mainly includes light weight and improvement of fuel and drive efficiency. The emergence of three-cylinder engines is the small displacement and highly integrated lightweight engines developed by automobile manufacturers in response to increasingly stringent emission standards. [0003] The lower block is the lower half of the engine block, also known as the lower crankcase. The function integrates a closed cylinder, stores lubricating oil, filters and cools lubricating oil, and in...
