Abstract

The invention provides a variable oil pump cover machining method. The variable oil pump cover machining method comprises the following steps: (A) a pump cover to be machined is positioned on a rotating support plate through a positioning fixture; and firstly, the support plate is in a horizontal state; (B) the frontal surface of the pump cover is roughly machined; and the machining contents comprise rough milling of a shaft side plane, milling of a shaft end surface and a cover plane and drilling of a shaft hole and a hole orifice chambering angle; (C) the frontal surface of the pump cover is finely machined; and the machining contents comprise coating and turning of the shaft side plane and finish boring of the shaft hole; (D) the support plate rotates to be positioned in a direction of 15 degrees; and (E) an inclined oil hole in the inclined surface of the pump cover is drilled. The method is high in machining precision and short in machining time.

Description

technical field [0001] The invention relates to the production field of a variable-variable oil pump, in particular to a method for processing a pump cover of a variable-variable oil pump. Background technique [0002] Due to the complex design and structure of the variable oil pump, there are multiple compound angles on the workpiece during processing, and the processing can only be completed after one clamping on the special machine tool for this product. The vertical machining center refers to the machining center with the main shaft in a vertical state. Its structure is mostly a fixed column. The workbench is rectangular and has no indexing and rotating function. It is suitable for processing discs, sleeves, and plate parts. It generally has three linear motions. Coordinate axis, and a turntable that rotates along the horizontal axis can be installed on the workbench to process helical parts. When machining the oil pump cover, it is necessary to process the cover plane ...
