Abstract

The invention provides a high-pressure common rail shaft fixture and an application method thereof. The high-pressure common rail shaft fixture comprises a support mechanism and a clamping mechanism;the support mechanism comprises oil nozzle V-shaped frames and rail body V-shaped frames; two sets of the oil nozzle V-shaped frames are provided, and are separately arranged on two sides of the railbody V-shaped frames; the centers of arc walls of two sets of the rail body V-shaped frames are coaxially arranged; the oil nozzle V-shaped frames are positioned below axle wires of the rail body V-shaped frames; and tightening mechanisms comprise center clamps arranged corresponding to the oil nozzle V-shaped frames, and clamping clamps separately arranged on two sides of the center clamps. The high-pressure common rail shaft fixture achieves the effects of stable clamping of circular rail bodies, simple fixation and quick disassembly.

Description

technical field [0001] The invention belongs to the field of high-pressure common-rail shaft production, and in particular relates to a fixture for a high-pressure common-rail shaft milling program. Background technique [0002] In the application of high-pressure common rail shaft and common rail technology, that is, in the closed-loop system composed of high-pressure oil pump, pressure sensor and ECU, a fuel supply method that completely separates the generation of injection pressure and the injection process from each other. The volume of the common rail shaft is to reduce the oil supply pressure fluctuation of the high-pressure oil pump and the pressure oscillation caused by the fuel injection process of each injector, so that the pressure fluctuation in the high-pressure oil rail is controlled below 5MPa. [0003] The structure of the high-pressure common rail shaft includes a circular rail body, two flanges are arranged side by side on the same side of the same plane o...
